A total of 200, day-old commercial Arbor Acres chicks were reared for 42 days. The chicks were weighed individually and randomly assigned into equally 4 treatment groups having 5 replicates. Chicks of control group T0 were raised on a basal diet with no supplement. The chicks of group T1, T2 and T3 were supplemented with curcumin 300 mg/kg, lutein 300 mg/kg, and curcumin plus lutein 150 mg each with per kg of feed, respectively. On day 21 all the chicks were challenged with Eimeria maxima. The findings of this study revealed that among all the groups feed intake, body weight gain and feed efficiency remained statistically unchanged (P>0.05). A significantly higher (P<0.05) liver and spleen weights were observed in the T0 group as compared to the birds fed lutein supplemented diets whilst the bursa and thymus remained statistically alike and the same trend was observed for bloody diarrhea, intestinal lesion scores except for the oocyte count which was significantly lower in the T3 group. On day 20, T3 dietary groups exhibited numerically increased antibody titers against Newcastle disease virus (NDV) and Avian infl uenza virus (AIV), additionally T3 also exhibited the same trend on day 30. The serum malondialdehyde (MDA) and aspartate aminotransferase (AST) levels were at a lower rate in the T3 group while the liver MDA was statistically lower in the T1 (P<0.05) group as compared to other groups. The alanine aminotransferase (ALT) remained unchanged within the groups. Compared to T0 (control), all the carotenoid supplemented groups exhibited increased (P>0.05) shank color and skin b* value (yellowness). Our conclusion showed that application of curcumin single or in combination with lutein may promote skin pigmentation, lowered liver injury, and exhibit a better anti-coccidial impact.

There are several evidences have been reported by different scientists on influence of antimicrobial drugs on the unlike herbal extorts in various parts of world (Rajput et al., 2012; Jarić et al., 2015; Alabi et al., 2017). Medicinal herbs and their extracts are among the alternative sources of allopathic growth enhancers are already being in use (Jarić et al., 2015). The medicinal herbs could be an excellent alternative source of allopathic growth promoters, with lower expenditure of manufacturing, and abridged danger of toxicity, least hazards for health and friendly environment, since the physical condition of intestinal gut plays vital role in the continuance of better development with most important function of absorption Abstract | The present study was designed to evaluate the effect of herbs on the performance of broiler chickens challenged with coccidiosis. A total of 450 broiler chickens were allotted into 6 groups (n = 75/group). Group A controlled without supplementation, Group B, C and D were supplemented with Aloe barbadensis (5ml/L), Ferulafoetida regal (500mg/L), Tamarindus indica (50mg/L), respectively. Group E and F were supplemented with a mixture of all 3 herbs/plants at 2ml/L; mixed with distilled water and another with citric acid. The dressing percentage was observed significantly (P < 0.05) higher in compound II supplementary group F and lowest in control group A. Whereas, the fat pad percentage recorded significantly (P < 0.05) lowest in the compound II supplementary group F and highest in control group A. The relative weight of organs; liver, pancreas, spleen, heart, duodenum, jejunum, ileum, thymus and ceaca was observed significant (P < 0.05) in the herbs supplementary groups as compared to control group. The compound-II supplementary group F significantly (P < 0.05) increased the percentage of crude protein and fat contents as compared to control and other groups. Histomorphological examination of liver of broiler chicken supplemented with Compound-I and Compound-II in the coccidiosis challenged broiler chickens showed few pathological changes as compared to control (coccidiosis induced and without supplementation) group. In conclusion, supplementation of herbs mixture (Group E and F) at the dose 2ml/L to the coccidiosis challenged broiler chickens improve the overall performance and liver function.

Recently, interest in using carotenoids as feed ingredients has increased markedly owing to their bioactive and health‐promoting properties. In terms of applications, carotenoid‐rich products are widely available in the form of food and feed additive, supplements and natural colourants. Carotenoids play a versatile biological role that contributes to therapeutic effects, including anticancer, immunomodulators, anti‐inflammatory, antibacterial, antidiabetic and neuroprotective. Dietary supplementation of carotenoids not only improves the production performance and health of poultry birds, but also enhances the quality of egg and meat. Several studies have suggested that the supplementation of plant derived carotenoids revealed numerous health‐promoting activities in poultry birds. Carotenoids re...

Broiler chickens are sensitive to heat stress mainly due to not having sweat glands. The current study was conducted to observe the effect of heat stress on performance of Ross-308 broiler chickens. 1600 Ross-308 broiler day old chicks were obtained from local hatchery and randomly divided into two groups, the heat stress group A (n=800) and heat free group B (n=800). Group A was reared in high temperature (101 0 F) whereas group B was reared in ideal temperature. To evaluate the physiological stress indicators blood glucose levels and total blood cell count were checked on day 21 and 28. The parameters observed were; feed intake, body weight gain, feed conversion ratio, water intake and carcass yield. The results indicated that feed intake, weight gain, water intake, feed conversion ratio and carcass yield were significantly higher in group B compared to group A. It was concluded that heat stress has deleterious effect over the performance of broiler Ross-308 chicken.

Two hundred and forty 1-day-old Arbor Acres broiler chicks were randomly distributed into four treatment groups with six replicates in a randomized block design. Birds were fed basal diet for 42 d with or without supplementation of marigold flower extract at various concentrations, i.e., 0 (MG0, control), 100 (MG100), 150 (MG150) and 200 (MG200) mg/kg of feed, respectively. Feed intake and live body weight were weekly recorded. Carcass and shank color, and antibody titers against Newcastle and Influenza viruses were measured. Results showed that marigold flower extract significantly (p<0.05) improved live body weight and relative thymus weight. However, feed intake, feed conversion ratio (FCR), and spleen and bursa weights were not significantly affected. Yellowness (b*) of breast and thigh muscles increased by the dietary supplementation of marigold flower extract compared with the control diet. However, lightness (L*), redness (a*) and redness to yellowness ratio (a/b) were not influenced by the treatments. Moreover, Roche color fan scores of the shank skin were increased at market age (d 42). The results revealed that marigold extract enhanced antibody titers against Newcastle and influenza viruses. It was possible to conclude that the dietary supplementation with marigold flower extract at the rate of 200 mg/kg of feed enhanced carcass and shank color, antibody titers against ND and AI, and growth performance of broiler chickens.

Nine replicates of chicken breast meat samples were used for each cycle. Lipid oxidation was determined by measuring peroxide value, and malondialdehyde (MDA) concentrations, which reflect thiobarbituric acid reactive substance (TBARS). Color was determined with a digital colorimeter. Muscle moisture contents were determined by drip loss and thawing loss, water holding capacity, and nuclear magnetic resonance (NMR). The results showed that, as the number of freeze-thaw cycles increased, meat redness decreased and MDA and peroxide values increased. Drip loss and thawing loss tended to decreasing as the number of freeze-thaw cycles increased. Water holding capacity also decreased as a function of increasing freeze-thaw cycles. NMR relaxometry profile showed freeze-thaw cycles change the water distribution of meat subjected to multiple freeze-thaw cycles. In conclusion, multiple freezing and thawing rate (6 cycles) increased lipid oxidation, decreased myowater, and impaired the color of chicken meat.

Four hundred eighty, 1-day-old Arbor Acre broiler chicks were allocated into four groups with 6 replicates of 20 birds per cage. Birds were fed a corn-soybean basal diet supplemented with curcumin at 0 (control, CRM0), 100 (CRM100), 150 (CRM150) and 200 mg/kg (CRM200) levels for 42 days. All birds were kept in wire floor triple deck battery cages under semi-intensive housing management. The results revealed that dietary supplementation of curcumin at 200 mg/kg significantly improved live body weight and feed efficiency at marketing age (42 d); while, there was no significant difference on feed intake as compared to control. Curcumin significantly improved utilization of apparent metabolizable energy and decreased abdominal fat at 42 d in CRM150 and CRM200 broilers, respectively. Plasma T4 hormone level and fat utilization were significantly increased; while plasma cholesterol level was significantly reduced in dose dependent manner for CRM200 broilers. The results showed that dietary supplementation of curcumin influenced the histomorphological measurements of small intestinal villi. The villus height was significantly increased in duodenum, jejunum and ileum in curcumin supplemented broilers. Villus width was also significantly increased in duodenum and jejunum (42 d). While, there was no significant difference in ileum villus width. Furthermore, villus height to crypt depth ratio was significantly increased in all segments (except jejunum 42 d) of small intestine in CRM200 group; however, the intestinal crypt depth was lowered in curcumin supplemented broilers. In conclusion, supplementation of curcumin at 200 mg/kg feed enhanced the growth performance and fat metabolism, and increased villus absorptive area of small intestine, resulting in improved nutrients absorption in CRM200 group.
