Effect of feed restriction with or without garlic supplementation on growth performance, blood biochemical profile and carcass characteristics in male broilers

ABSTRACT: This study identified the effects of dietary supplementation with ractopamine, chromium picolinate, chromium yeast, or an energetic feed restriction on the growth performance and lipid profile of subcutaneous fat, in late finishing gilts. Twenty genetically similar gilts with initial body weight of 105.35 ± 4.77 kg and a final body weight of 131.37 ± 5.58 kg were distributed in a completely randomized block design with five treatments (control; ractopamine: 20 ppm; chromium picolinate: 0.48 ppm; chromium yeast: 0.80 ppm; and energetic feed restriction: -150 kcal kg-1 of metabolizable energy), with four replicates of one animal each. The experimental diets were isonutritives, except for the metabolizable energy level of the diet fed to the group subjected to energy restriction. There were no effects on the growth performance and carcass characteristics. Ractopamine and organic chromium (picolinate and yeast) supplementation increased the concentration of total polyunsaturated fatty acid. The proportion of α-linolenic fatty acids were higher when the diets were supplemented with ractopamine or chromium yeast. The energy restriction increased the n-6:n-3 ratio and reduced α-linolenic acid concentration. Therefore, ractopamine, chromium picolinate, chromium yeast supplementation, and energetic feed restriction did not affect the growth performance or carcass characteristics but altered the lipid profile of subcutaneous fat in finishing gilts. Ractopamine and organic chromium supplementation increased PUFA in the fat of finishing female pigs.

Background: Earlier antibiotics were used for growth promotion and prophylactics against gastrointestinal diseases but the injudicious use of antibiotics could lead to bacterial resistance and certain amount of residues in animal products. Therefore, maintenance of intestinal microflora balance through a non-antibiotic approach is urgently needed and for that probiotics is now preferred over antibiotics. The application of probiotics had gained significant attention in developing suitable alternatives of antibiotics in the swine industry.Methods: The experiment was conducted by considering n=27 number female post weaned piglet which were distributed into three groups (3 replicates of 3 each) and supplemented with basal diet either without probiotics (C) or with a probiotic of dairy-based (Lactobacillus acidophilus NCDC-15) or swine based (Pediococccus. acidilactici FT28) to evaluate the effect of probiotics on growth performance, nutrient digestibility, blood biochemical profile, immune status and faecal microbial count in growing pigs.Conclusion: Improvement in terms of growth performance, digestibility of CP, N retention found. The serum A: G ratio, triglyceride, glucose and cholesterol level lower (p less than 0.05) in TPedic group compared to other treatment groups. The cell-mediated and humoral immune response was significantly higher (P less than 0.001) in probiotics supplemented animals, nonetheless, swine based probiotic had better (P less than 0.001) response as compared to dairy based probiotics.
