Background and Aim: Dietary supplementation with green tea by-product shows special effects on animal parameters. This study aimed to assess the effects of green tea by-products (GTBP) in the diet on some blood parameters, growth performance, and carcass characteristics of finishing pigs and on meat quality, and nutritional composition of pork. Materials and Methods: One hundred and sixty crossbred pigs with an initial body weight of 65.15 ± 0.38 kg, were distributed into four dietary treatments, with four replicates of 10 pigs each. The dietary treatments were a basal diet (control diet, CON), and three experimental diets (GTBP8, GTBP16, and GTBP24) based on the CON diet supplemented with GTBP at 8, 16, and 24 g/kg of feed. The studied parameters were examined during the experimental period of 10 weeks. Results: No statistical differences in average daily feed intake, average daily gain, and feed conversion ratio were observed between the diet treatments (p > 0.05). Backfat thickness decreased (linear, p < 0.05) according to the GTBP levels but no other carcass parameters. Meat quality was not influenced by the GTBP levels (p > 0.05). However, pigs fed with GTBP had a decrease in cholesterol content and an increase in crude protein and total omega-3 content of pork compared to the CON diet (p < 0.05). Moreover, dietary supplementation with GTBP significantly decreased plasma cholesterol (p < 0.05), and trends for the decrease in low-density lipoprotein cholesterol and urea nitrogen were observed (linear, p = 0.08). Conclusion: Up to 24 g/kg GTBP in the diet for finishing pigs does not impair animal performance and makes carcass leaner with softer meat as well as positive effects on cholesterol and fatty acid metabolism. Further experiments are needed to determine the optimal levels of GTBP addition in finishing pig diet to produce higher meat quality.
Effects of dietary phytogenic product on the performance and immune response of pigs
Bulletin of the Veterinary Institute in Pulawy, 2013
The aim of the study was to determine the effects of supplementation of sows’ and weaners’ diet with Stresomix, preparation containing extracts from Magnifera indica, Withania somnifera, Phyllanthus emblica, and Ocimum sanctum, on pig performance and immunity under field condition. The hypothesis was that anti-inflammatory, antistress, and immunomodulatory properties of the herbs would enhance production parameters and immune response, according to the manufacturer's claim. The study was performed on 16 sows and 160 piglets. The following parameters were recorded: concentration and proportion of white blood cells and their populations, concentration of serum immunoglobulins, specific humoral postvaccinal response after vaccination against swine influenza and swine erysipelas, and main production parameters. No significant differences among treatment groups were found with regard to concentrations of leukocyte subpopulations and immunoglobulins, as well as all investigated produc...

This study was carried out to investigate the hematological and serum biochemical parameters of weaned pigs fed maize cob-cassava peel mixture as partial replacement for maize. A total of36crossbreed male piglets with initial body weight (6.07±0.02 kg) of about 7-8 weeks’ old were randomly distributed into four groups of nine animals per treatment. Each treatment was further divided into three replicates consisting of three pigs in a completely randomized design. Pigs in treatment 1 were fed 0 % maize cob-cassava peel mixture (CPMCM) while CPMCM was used to replace maize at 10 % (T2), 20 % (T3) and 30 % (T3). Phytochemical evaluation of CPMCM revealed the presence of alkaloids (19.10 mg/kg), tannins (8.17 mg/kg), saponins (9.11 mg/kg), cyanide (16.50 mg/kg), flavonoids (12.86 mg/kg) and phenol (7.72 mg/kg). All the hematological parameters: red blood cell, pack cell volume, haemoglobin, mean corpuscular haemoglobin, mean corpuscular volume, mean corpuscular haemoglobin concentration, white blood cell, monocytes, basophils and lymphocytes were significantly (P<0.05) influenced by the treatment except for platelet values (P>0.05). Similarly, total protein, total bilirubin and gluscose levels were significantly different (P<0.05) among the treatments except for cholesterol, urea, creatinine, activities of alkaline phosphatase, alanine transaminase and aspartate transaminase were not influenced by the treatment (P>0.05). However, values were within the normal range for heathy weaner pigs. It was concluded that CPMCM can be used to partially replace maize up to 30 % without having any negative effect on the health status of pigs.
Protein quality evaluation and hematological parameters of rats fed complementary diets
The protein quality of cassava-based complementary diets was assessed by feeding albino rats. Hematological parameters were also evaluated. A basal diet (nitrogen-free) was formulated along with four different 10% protein diets and a casein diet as reference. The 48 weanling rats used in the experiment were divided into 6 groups of 8 rats each, and each group was allotted to the different diets. The rats were housed individually. In general, the protein quality indices of the diets showed some variations and the hematological parameters obtained for animals fed casein (reference) diet being significantly higher (P < 0.05) than the corresponding values for test diets. The protein efficiency ratio (2.37-2.45), biological value (90.12-93.52%), true digestibility (76.50-84.68%), net protein utilization (71.77-83.13%) and net protein ratio (3.53-3.67) of the diets indicated good growth promoting quality of the proteins. Hematological parameters of the rats fed the test diets were with...
Blood Profile of Growing Rabbits Fed Pro-Vitamin A Fortified Cassava Peel Meal Based Diets
Agricultura, 2021
The effect of feeding pro-vitamin A cassava peel meal (PCPM) based diets to growing rabbits (n=48) for 61 days on their haematology and serum biochemical parameters was investigated. T1, T2, T3, and T4 diets were formulated with inclusion levels of 0, 15, 30, and 45%, respectively. In a completely randomized design, the rabbits were randomly allocated to four experimental groups of twelve animals each, with four rabbits constituting a replicate. On the last day of the study, blood samples were taken from each animal and analyzed for haematological and serum biochemical indices. The results of the proximate composition of experimental diets revealed that T2, T3, and T4 had high (p<0.05) ash values. T1 diet had higher (p<0.05) metabolizable energy (ME) in comparison with T3, and T4 diets. Red blood cells (RBC) and white blood cells (WBC) were improved (p<0.05) significantly in 15, 30, and 45% PCPM inclusions. T3 and T4 had better (p<0.05) packed cell volume (PCV) values, h...
Thirty-six growing pigs (Large white x Landrace x Duroc) weighing 27.56±0.51kg were allocated to three groups of Avizyme® 1300 inclusion (100g/100kg diet and 200g/100kg diet) in a 45% Cassava peel meal (CPM) based diet and a control (no enzyme inclusion). The diet with no enzyme inclusion resulted in the least performance, while the pigs on diet supplemented with 100g/100kg diet had the best result in terms of daily weight gains, protein efficiency and feed conversion ratios. The enzyme inclusions had no significant (P>0.05) effect on the serum metabolites, hematological parameters and serum electrolytes but for slight variations (P<0.05) observed in the values of MCHC andPO4 2-. The result suggests 100g Avizyme® 1300 inclusion in 100kg of 45%-CPM based diet as ideal for growing pigs.

Green tea has a long-standing reputation for its health-promoting properties. It has a useful content of amino acids, proteins, vitamins, tannins and polyphenols, such as epicatechin, epigallocatechin, epigallocatechin gallate and gallocatechin. This study evaluated the potential use of green tea byproducts in finishing pig diet. A total of 100 finishing pigs were assigned to 5 dietary treatments with 4 replications for 6 weeks in a completely randomized design. The treatments were as follows: control (basal diet), antibiotic (basal diet with 0.003% chlortetracycline), and basal diet with 0.5, 1 or 2% green tea by-products (GTB). In this experiment, a poor weight gain and feed conversion ratio was observed for the GTB-2% group when compared with the antibiotic group. Both crude protein and crude fat contents of the meat were inversely proportional to each other in the GTB groups and 0.5 to 1% level differed with the antibiotic group. The slaughter weight and shear value were higher in GTB-1 and 0.5%, group respectively, while a lower heating loss and higher tenderness were observed in the GTB-2% group. Supplementation of the pig diet with GTB reduced the thiobarbituric acid reactive substances values of the meat, and increased white blood cells (WBC) and red blood cells (RBC) content compare to others. Although, spleen weight was decreased in the GTB-1 and 2% groups, spleen cells growth and, IL-6 and TNF-α production were improved by the addition of GTB to the feed. These combined results indicated that 0.5 to 1% GTB hold great promise to use as feed additive for finishing pigs.
Effect of various dietaryprotein levels on haematology and
2016
Protein is very crucial for growth of birds.Blood parameters are used as indicator for diagnosis of diseases. Haematological values also reflect the levels of stresses due to nutritional and environmental factors. The present study was conducted to evaluate the effect of various dietary protein levels on haematological and blood biochemistry values in different close bred flocks of Japanese quail. One thousand and eighty, day-old chicks from four different close bred flocks comprising 270 chicks having 135 of each separate sex (♂ and ♀) were divided into 3 subgroups assigning 3 different protein levels (21, 23, 25%) having 3 replicates comprising 15 birds each. From 4th week onward 72 birds (randomly picking one bird from each replicate) were slaughtered at the end of each week. The blood samples were collected in the tubes from the jugler vein by slaughtering the birds. The blood was analysed following standard procedure to study the haematological and blood biochemistry. The results showed that strains of Japanese quail did not differ significantly in haematological parameters andblood cholesterol level from 4 th to 6 th week in both sexes. However, strains differ in total protein, albumin and globulin content in blood. Dietary protein level significantly affected most of haematological and biochemical parameters of blood. Highest protein level (25%) showed best performance in all the parameters except hemoglobin and cholesterol level. It is concluded that 25% protein level in feed is best for rearing of Japanese quail for meat purpose in tropics.

To determine the effects of inclusion, at different levels of Moringa oleifera leaf meal (MOLM) in growing pig diets on pig’s daily feed intakes (DFI), growth performance, feed conversion efficiency (FCE), haematology and plasma lipid indices, a total 24 pigs aged 2.5 months old were selected and assigned to 4 treatment diets (T) containing: 0% (T1), 3% (T2), 6% (T3) and 12% (T4) MOLM concentrations, each with 2 replications of 3 pigs. The DFI and weekly pig weights were monitored for 7 weeks, after which 2 sets of blood samples were drawn from 2 pigs per replication for haematology and serum lipid determination. The DFI for the T4 (3.16 kg) was significantly higher than T1 (2.90 kg), T2 (2.61 kg) and T3 (2.54 kg). Pigs in T2 had significantly higher daily weight gains (0.836 kg) compared to T1 (0.807 kg), T3 (0.810 kg) and T4 (0.810 kg) groups. Furthermore, pigs in T2 and T3 had significantly higher FCE (31.57 and 31.23% respectively) compared to T4 (28.05%) and T1 (30.31%). Inclus...
