One hundred and eighty 1-day-old Abor acre broiler chicks were used for the experiment that lasted 42 days. Birds were randomly allotted to 5 treatments of 6 replicates with 6 birds each. Frog meal was used to replace fish meal at a level of 0%, 25%, 50%, 75% and 100%, respectively. Results showed there were no significant differences observed in the total serum protein and globulin of birds on the experimental diets. However, the albumin and albumin/ globulin ratio of birds on 50% and 100% frog meal level respectively compared with birds on the control diet. The urea level of birds on 100% fish meal and 100% frog meal was similar. There were no significant differences observed in the packed cell volume, mean corpuscular haemoglobin concentration, lymphocyte and hetero...

Supplementation of such diets with NSP degrading enzyme helps to improve digestibility of the nutrients entrapped in the wheat cell wall thereby improving performance and carcass quality of broiler chickens. The effect of Roxazyme G2G (a cocktail of carbohydrase enzymes) supplementation on growth performance and carcass characteristics was investigated in a 42-day experiment using 120 one-day-old unsexed broiler chickens (Arbor acre strain) fed wheat-based diets without or with enzyme supplementation. The birds were randomly allotted to 3 dietary treatments. Each diet had 4 replicates of 10 birds each in a completely randomised design. Performance indices measured were the body weight gain, feed intake, feed conversion ratio and feed efficiency ratio. At day 42, birds were weighed and slaugh...

Thus, humans have been paying more attention to health, thereby reducing consumption of cholesterol enriched food. Egg is considered as one of the major sources of human dietary cholesterol. However, an alternative way to reduce the potential cholesterolemic effect of eggs is to modify the fatty acid composition of the yolk. The effect of palm oil (PO), soybean oil (SO), sesame seed oil (SSO) and fish oil (FO) supplementation in the diets of layers on egg yolk fatty acid, cholesterol, egg production and egg quality parameters were evaluated in a 42-day feeding trial. One hundred and five Isa Brown laying hens of 34 weeks of age were randomly distributed into seven groups of five replicates and three birds per replicate in a completely randomized design. Seven corn-soybean basal diets (BD) were formulated: BD+No oil (T1), BD+1.5% PO (T2), BD+1.5% SO (T3), BD+1.5% SSO (T4), BD+1.5% FO ...

In a 42-day study, 200 one-day old Arbor Acre broilers were weighed and randomly allotted to 5 dietary treatments with 5 replicates having 8 birds in each group. The treatments were basal diet (negative control, NC), NC + 0.05% antibiotics (positive control, PC), NC + 3% CP, NC + 3% CO and NC + 1.5% CP + 1.5% CO in a completely randomised design. The growth performance indices were measured. On day 42, blood samples were collected, gut microbial population and histopathology were assayed following standard procedure. Results showed that average daily weight gain (g/bird/day) of birds on NC, PC and combination of 1.5% CP + 1.5% CO leaf meals were significantly similar at the finisher phase. The feed intake of birds on NC and PC was higher than those on 3% CO and combination of 1.5% CP + 1.5% CO leaf meals. The ...

The experimental design was a Randomised Complete Block Design. Poults were brooded for 7 days, after which they were allotted to 4 dietary treatments with 4 replicates of 8 birds per replicate. Treatment 1 was the basal diet with no supplements while treatments 2, 3, and 4 were supplemented with antibiotics, probiotics and synbiotics respectively. On day 56, birds were slaughtered and digesta samples from the ileum were collected for microbial load count and intestinal pH. After flushing out the digesta samples, sections of the ileum (5cm posterior to Meckel’s diverticulum) were removed for ileal morphological measurements. Probiotic and synbiotic supplementation significantly (P<0.05) reduced the total colifo...

One hundred and twenty layers aged 34 weeks old were allocated to five dietary treatments with eight replicates and three birds per each replicate. The birds were fed diets supplemented with graded levels of L-Dopa (0, 0.1, 0.2, 0.3 and 0.4%) in a completely randomized design. Performance parameters were monitored. On the day 42, egg, meat and blood samples were obtained to determine total cholesterol and lipoproteins using standard procedures. The ileal digesta was collected for microbial analysis. The results indicated that inclusion of L-Dopa in the diet did not affect the performance parameters and egg cholesterol profile. Serum cholesterol levels of birds fed the control diet and those on 0.1% and 0.2% L-Dopa supplemented diets were similar, but significantly higher than those fed 0.3% and 0.4% L-Dopa.

Two hundred and forty one-day-old Arbor Acre broiler chicks were randomly assigned to five dietary treatments with six replicates, each with eight birds. The treatments were basal diet (negative control, NC), basal diet + antibiotic (positive control (PC)), NC + 0.4% organic acid (OA), NC + 0.3% probiotic (PB) and NC + 0.4% OA and 0.3% PB. Reduced body weight gain (BWG) was recorded for birds on the NC diet at the starter phase and over the total period. The addition of OA significantly increased BWG compared to values obtained in birds on the NC and other diets. Diet had no effect on BWG at the grower phase or on feed intake, dry matter intake and feed conversion ratio in any growth phase. Gain : feed ratio was lowered in the NC diet, but improved significantly by OA and PB in the starter phase. Organic acid supplementation reduced the weight of the bursa of Fabricius. The weight of pancreas, height of villi and crypt depth were reduced in birds on the NC diet compared with those on OA, PB and a combination of these. Diet had no effects on the weights of the lungs, heart, spleen, kidneys, liver, villus width, villus height : crypt depth ratio, lactic acid bacteria, coliform bacteria and total bacterial count in any gut section. In conclusion, supplementation of broiler diets with OA and PB could improve their growth and gut morphology better than antibiotics would, with a greater positive effect in the starter phase.

Diet 1 was the basal diet with no supplement while diets 2, 3, 4 and 5 were supplemented with antibiotic, probiotic, carbohydrase and combination of probiotic and carbohydrase, respectively in a randomized complete block design. The experiment was carried out at the Poultry Unit of the Teaching and Research Farm, University of Ibadan, Nigeria between March and April, 2013. 240 one-day-old broiler chickens were allotted to 5 diets with 6 replicates of 8 birds each in a 35-day experiment. On day 35, birds were sacrificed and digesta samples from the duodenum, ileum, caecum and colon were collected for microbial load count. Digesta viscosity and pH from the ileum were also determined. Sections of the ileum were obtained for morphological measurements. Result showed that diet had no effect on the feed intake, dry matter intake and feed conversion ratio of birds at starter (d 0-21), grower phases (d 22-35) and overall period (d 0-35). Body weight gain was significantly (P = .05) improved at d 0-21 and 22-35 with the addition of probiotic and/or carbohydrase but not at d 0-35. Diet had no effect on the microbiota in the various segments of the GIT of birds. Coliform counts of birds fed diet supplemented with carbohydrase were significantly (P = .05) higher (5.64 x 106 cfu/ml) than the values in other diets. The crypt depth, villus height, villus width and villus height:crypt depth ratio were not affected by diet. Highest digesta viscosity (1072mPa) was recorded in birds on the negative control while the least digesta viscosity (529mPa) was observed in birds on diet supplemented with carbohydrase enzyme. It is concluded that probiotic and/or carbohydrase are viable feed supplements in wheat-based diets for broilers.

They were randomly assigned to 5 dietary treatments with 6 replicate groups of 8 birds each. A corn-soyabean-based diet was formulated to serve as the basal diet (negative control, NC) at both starter and grower phases. The basal diet+antibiotic was the positive control (PC). The other test diets were basal diet+1.0% probiotics (PB), basal diet+0.05% mycotoxin binder (MB), and basal diet+1.0% PB and 0.05% MB. Body weight gain (BWG), feed and dry matter intake were significantly (P<0.05) improved in birds fed the PB and MB diets over the NC diet but not up to the PC diet at starter phase only. The Feed Conversion Ratio (FCR) was not influenced by dietary treatments at both starter and grower phases but gain: feed (G: F) was significantly (P<0.05) influenced by dietary treatments at 0 to 35 d, with improved G: F observed in birds fed NC+MB and NC+PB+MB diets. Weight of pancreas was remarkably (P<0.05) higher in birds fed diets supplemented with MB, PB and PB+MB over the controls. The villus height of birds fed NC+PB was significantly (P<0.05) improved than other dietary treatments, while the crypt depth of birds fed NC+PB and NC+MB was significantly (P<0.05) improved over the controls and NC+PB+MB diets. Microflora count in the gut sections showed significant (P<0.05) increase in coliform load in the duodenum, ileum and caecum in birds fed NC diet. However, in the ileum, there was a significant (P<0.05) increase in LAB in birds on NC+PB diet.

One hundred and eighty seven-day-old Arbor acre broiler chicks were randomly allotted to 5 dietary treatments in a completely randomised design. Each diet had 6 replicates with 6 birds each. At week 5, two birds per replicate were placed in metabolic cages for a 3-day excreta collection for digestibility determination. At week 6, same sets of birds from each replicate were sacrificed, the digestive tract excised and digesta samples were collected at the terminal ileum. Also, two birds from each replicate were slaughtered by cutting through the jugular vein for carcass characteristics and organs were harvested and weighed. Results showed that there were no significant differences in the final weight, weight gain and feed conversion ratio recorded for birds among the treatments. However, the feed intake, protein intake (PI), protein efficiency ratio (PER), ileal and excreta crude protein digestibility of birds were significantly (P<0.05) influenced by the dietary treatments. Highest feed intake was recorded for birds on 50% Frog Meal (FRM) and 50% Fish Meal (FM), though similar to what was obtained in birds fed other levels of FRM inclusion. Identical PI was recorded for birds on the control diet, 25 and 50% FRM diets and were considerably higher (P<0.05) than PI observed in birds on 75 and 100% FRM. Highest PER (2.21) was observed in birds on 100% FRM diet which was similar to those on 75% FRM inclusion level but least PER (1.99) was recorded for birds on the control diet. Ileal and excreta CP digestibility coefficients of birds on the experimental diets varied significantly (P<0.05). Highest ileal CP digestibility coefficient (0.75) was recorded in birds fed 50% FRM and 50% FM while the least (0.65) value was observed in birds fed 100% FRM. There were no significant differences recorded in the primal cuts and organ weights of birds except for head, drumstick, thighs and shanks. It is concluded that frog meal can replace fish meal up to 100% in broiler diets without adverse effect on performance.

Two hundred one-day old broiler chicks were randomly allotted to 4 treatments with 5 replicates of 10 birds each in a completely randomized design. Diet 1: basal diet without feed additives. Diet 2: basal + coccidiostat (0.06%), Diet 3: basal + 2.5% fish oil and Diet 4: basal + 5% fish oil. Performance indices were measured. On day 56, distal ileum of two birds per replicate were severed for gut morphological measurements and digesta samples were collected for protozoan load counts. About 5cm of the jejunum, ileum and caeca were excised for histological examinations. The results showed that dietary fish oil supplementation did not have significant effect on the performance of broiler chickens at the starter phase. However, there was a negative effect of the fish oil in the final weight and feed conversion ratio of birds at the finisher phase. Final weights of birds that ...

Three hundred and sixty 35-day old Arbor Acre broiler chicks were randomly allotted to a Nitrogen-Free Diet (NFD) and five semi-purified diets containing each of the test feedstuffs (maize, wheat, SM, GC and RB) as the sole source of protein. Diets were fed to ten birds of six replicates up to day-42 in a randomised complete block design. Chromic oxide (5 g/kg) was added to the feed as an indigestible dietary marker. Six birds per replicate were asphyxiated with CO2 and digesta samples were collected from terminal ileum on day 42. The endogenous amino acid losses (EAAL), apparent ileal amino acid digestibility (AIAAD) and SIAAD were estimated. Highest EAAL concentration was found in threonine (0.29g/kg), while glutamic acid and alanine (0.03g/kg) had the least. Total AIAAD were 69.47, 59.49, 70.48, 73.04 and 62.21%...

Two hundred and forty one-day-old Arbor Acre broiler chicks were randomly assigned to five dietary treatments with six replicates, each with eight birds. The treatments were basal diet (negative control, NC), basal diet + antibiotic (positive control (PC)), NC + 0.4% organic acid (OA), NC + 0.3% probiotic (PB) and NC + 0.4% OA and 0.3% PB. Reduced body weight gain (BWG) was recorded for birds on the NC diet at the starter phase and over the total period. The addition of OA significantly increased BWG compared to values obtained in birds on the NC and other diets. Diet had no effect on BWG at the grower phase or on feed intake, dry matter intake and feed conversion ratio in any growth phase. Gain : feed ratio was lowered in the NC diet, but improved significantly by OA and PB in the starter phase. Organic acid supplementation reduced the weight of the bursa of Fabricius. The weight of pancreas, height of villi and crypt depth were reduced in birds on the NC diet compared with those on OA, PB and a combination of these. Diet had no effects on the weights of the lungs, heart, spleen, kidneys, liver, villus width, villus height : crypt depth ratio, lactic acid bacteria, coliform bacteria and total bacterial count in any gut section. In conclusion, supplementation of broiler diets with OA and PB could improve their growth and gut morphology better than antibiotics would, with a greater positive effect in the starter phase.

Diet 1 was the basal diet with no supplement while diets 2, 3, 4 and 5 were supplemented with antibiotic, probiotic, carbohydrase and combination of probiotic and carbohydrase, respectively in a randomized complete block design. The experiment was carried out at the Poultry Unit of the Teaching and Research Farm, University of Ibadan, Nigeria between March and April, 2013. 240 one-day-old broiler chickens were allotted to 5 diets with 6 replicates of 8 birds each in a 35-day experiment. On day 35, birds were sacrificed and digesta samples from the duodenum, ileum, caecum and colon were collected for microbial load count. Digesta viscosity and pH from the ileum were also determined. Sections of the ileum were obtained for morphological measurements. Result showed that diet had no effect on the feed intake, dry matter intake and feed conversion ratio of birds at starter (d 0-21), grower phases (d 22-35) and overall period (d 0-35). Body weight gain was significantly (P = .05) improved at d 0-21 and 22-35 with the addition of probiotic and/or carbohydrase but not at d 0-35. Diet had no effect on the microbiota in the various segments of the GIT of birds. Coliform counts of birds fed diet supplemented with carbohydrase were significantly (P = .05) higher (5.64 x 106 cfu/ml) than the values in other diets. The crypt depth, villus height, villus width and villus height:crypt depth ratio were not affected by diet. Highest digesta viscosity (1072mPa) was recorded in birds on the negative control while the least digesta viscosity (529mPa) was observed in birds on diet supplemented with carbohydrase enzyme. It is concluded that probiotic and/or carbohydrase are viable feed supplements in wheat-based diets for broilers.

They were randomly assigned to 5 dietary treatments with 6 replicate groups of 8 birds each. A corn-soyabean-based diet was formulated to serve as the basal diet (negative control, NC) at both starter and grower phases. The basal diet+antibiotic was the positive control (PC). The other test diets were basal diet+1.0% probiotics (PB), basal diet+0.05% mycotoxin binder (MB), and basal diet+1.0% PB and 0.05% MB. Body weight gain (BWG), feed and dry matter intake were significantly (P<0.05) improved in birds fed the PB and MB diets over the NC diet but not up to the PC diet at starter phase only. The Feed Conversion Ratio (FCR) was not influenced by dietary treatments at both starter and grower phases but gain: feed (G: F) was significantly (P<0.05) influenced by dietary treatments at 0 to 35 d, with improved G: F observed in birds fed NC+MB and NC+PB+MB diets. Weight of pancreas was remarkably (P<0.05) higher in birds fed diets supplemented with MB, PB and PB+MB over the controls. The villus height of birds fed NC+PB was significantly (P<0.05) improved than other dietary treatments, while the crypt depth of birds fed NC+PB and NC+MB was significantly (P<0.05) improved over the controls and NC+PB+MB diets. Microflora count in the gut sections showed significant (P<0.05) increase in coliform load in the duodenum, ileum and caecum in birds fed NC diet. However, in the ileum, there was a significant (P<0.05) increase in LAB in birds on NC+PB diet.

One hundred and eighty seven-day-old Arbor acre broiler chicks were randomly allotted to 5 dietary treatments in a completely randomised design. Each diet had 6 replicates with 6 birds each. At week 5, two birds per replicate were placed in metabolic cages for a 3-day excreta collection for digestibility determination. At week 6, same sets of birds from each replicate were sacrificed, the digestive tract excised and digesta samples were collected at the terminal ileum. Also, two birds from each replicate were slaughtered by cutting through the jugular vein for carcass characteristics and organs were harvested and weighed. Results showed that there were no significant differences in the final weight, weight gain and feed conversion ratio recorded for birds among the treatments. However, the feed intake, protein intake (PI), protein efficiency ratio (PER), ileal and excreta crude protein digestibility of birds were significantly (P<0.05) influenced by the dietary treatments. Highest feed intake was recorded for birds on 50% Frog Meal (FRM) and 50% Fish Meal (FM), though similar to what was obtained in birds fed other levels of FRM inclusion. Identical PI was recorded for birds on the control diet, 25 and 50% FRM diets and were considerably higher (P<0.05) than PI observed in birds on 75 and 100% FRM. Highest PER (2.21) was observed in birds on 100% FRM diet which was similar to those on 75% FRM inclusion level but least PER (1.99) was recorded for birds on the control diet. Ileal and excreta CP digestibility coefficients of birds on the experimental diets varied significantly (P<0.05). Highest ileal CP digestibility coefficient (0.75) was recorded in birds fed 50% FRM and 50% FM while the least (0.65) value was observed in birds fed 100% FRM. There were no significant differences recorded in the primal cuts and organ weights of birds except for head, drumstick, thighs and shanks. It is concluded that frog meal can replace fish meal up to 100% in broiler diets without adverse effect on performance.

Two hundred one-day old broiler chicks were randomly allotted to 4 treatments with 5 replicates of 10 birds each in a completely randomized design. Diet 1: basal diet without feed additives. Diet 2: basal + coccidiostat (0.06%), Diet 3: basal + 2.5% fish oil and Diet 4: basal + 5% fish oil. Performance indices were measured. On day 56, distal ileum of two birds per replicate were severed for gut morphological measurements and digesta samples were collected for protozoan load counts. About 5cm of the jejunum, ileum and caeca were excised for histological examinations. The results showed that dietary fish oil supplementation did not have significant effect on the performance of broiler chickens at the starter phase. However, there was a negative effect of the fish oil in the final weight and feed conversion ratio of birds at the finisher phase. Final weights of birds that ...

Three hundred and sixty 35-day old Arbor Acre broiler chicks were randomly allotted to a Nitrogen-Free Diet (NFD) and five semi-purified diets containing each of the test feedstuffs (maize, wheat, SM, GC and RB) as the sole source of protein. Diets were fed to ten birds of six replicates up to day-42 in a randomised complete block design. Chromic oxide (5 g/kg) was added to the feed as an indigestible dietary marker. Six birds per replicate were asphyxiated with CO2 and digesta samples were collected from terminal ileum on day 42. The endogenous amino acid losses (EAAL), apparent ileal amino acid digestibility (AIAAD) and SIAAD were estimated. Highest EAAL concentration was found in threonine (0.29g/kg), while glutamic acid and alanine (0.03g/kg) had the least. Total AIAAD were 69.47, 59.49, 70.48, 73.04 and 62.21%...

One hundred and twenty layers aged 34 weeks old were allocated to five dietary treatments with eight replicates and three birds per each replicate. The birds were fed diets supplemented with graded levels of L-Dopa (0, 0.1, 0.2, 0.3 and 0.4%) in a completely randomized design. Performance parameters were monitored. On the day 42, egg, meat and blood samples were obtained to determine total cholesterol and lipoproteins using standard procedures. The ileal digesta was collected for microbial analysis. The results indicated that inclusion of L-Dopa in the diet did not affect the performance parameters and egg cholesterol profile. Serum cholesterol levels of birds fed the control diet and those on 0.1% and 0.2% L-Dopa supplemented diets were similar, but significantly higher than those fed 0.3% and 0.4% L-Dopa. The levels of cholesterol an...

Two hundred and forty 21-day-old Abor Acre plus chicks were randomly allotted to six diets with varying levels of RB (100, 200 and 300 g/kg) without (0g/kg) or with Ronozyme® WX (25g/kg) supplementation in a 2x3 factorial arrangement using a randomized complete block design. Each treatment had 5 replicates with 8 birds each. The birds were fed for 5 days (d 22–26). On d 26, digesta was sampled from distal ileum. Data were analyzed using general linear model at α0.05. Lysine had the highest concentration among the essential amino acids (AAs) while the lowest concentration was observed for threonine. Rice bran at 10% for the essential amino acids with enzyme was significantly higher but compared with concentrations of RB at 10% and 20% without enzyme. There were no significant diffe...

Digesta viscosity, which is partly correlated with the modulation of gut can be reduced when wheat-based diets is supplemented with NSP degrading enzyme. In a 42-day trial, an experiment was conducted to evaluate the effect of Roxazyme G2G supplementation on digesta viscosity, gut microbial load, gut pH, and length between October and November 2012 using 120 day-old broiler chickens fed wheat-based diets with or without enzyme supplementation. Brooding of birds was for 7 days after which they were randomly allotted into 3 dietary treatments in a completely randomized design. The diet consisted 4 replicates of 10 birds each. Body weight gain, feed intake, feed conversion ratio and feed efficiency ratio were the growth performance indices measured. On day 42, birds were slaughtered and digesta samples from the Original Research Article
