This experiment was conducted to investigate the effects of various starvation and refeeding periods on growth, feed utilization and body composition in Asian sea bass (Lates calcarifer) with an average initial weight of 30.26±1.4 g (mean±SE). The fish were exposed to three different regimes: the control group fed twice daily to apparent satiation throughout the experiment (C), th...

BACKGROUND/AIMS The objective of this study was to examine the responses of p53 promoter methylation involved in kidney structure and function of early weaning intrauterine growth retarded (IUGR) rats to dietary folic acid supplementation. METHOD Sprague-Dawley rats were fed isocaloric diets containing either 21% protein diet (normal feed) or 10% protein diet throughout pregnancy and normal f...

Some persons argue that the routine addition of antibiotics to animal feed will help alleviate protein undernutrition in developing countries by increasing meat production. In contrast, we estimate that, if all routine antibiotic use in animal feed were ceased, there would be negligible effects in these countries. Poultry and pork production are unlikely to decrease by more than 2%. Average dai...

sesame oil cake (ssc) was bio-processed through solid state fermentation (ssf) under optimized conditions by a phytase-producing fish gut bacterium, bacillus subtilis subsp. subtilis (jx292128). ssf significantly reduced anti-nutritional factors (e.g., phytic acid, tannins and trypsin inhibitor) and crude fibre, while enhanced free amino acids, fatty acids and different minerals. phytase product...

the possibility of manufacturing and effects of a slow release non-protein nitrogen product on ruminant nutrition were evaluated in two separate experiments. in first experiment, making of slow release component was followed by connecting branched carbon chain to the molecule of urea to reduce the degree of solubility. then, the sample product was analyzed to assess its chemical structure, and ...

The study was conducted to determine optimum dietary inclusion level of Glyricidia leaf protein concentrate (GLPC), for growing rabbits. Thirty five weaned rabbits of mixed sexes were weighed and randomly allocated to five dietary treatments which contained 0, 5, 10, 15 and 20% GLPC for diets 1 to 5, respectively in a completely randomized design. Diet 1 served as the control diet.Each treatmen...

Two trials were conducted to determine the influence of realimentation diet energy, protein, B-vitamin (BV) and Lactobacillus acidophilus (LAC) content on recovery of rumen activity and feed consumption in beef steers. In trial 1, ruminal-fistulated steers were fasted and refed 1) prairie hay, 2) 10% protein (LCP), 3) 12.5% protein (MCP), 4) LCP + BV or 5) LCP + LAC. In trial 2, calves were fas...

The objective of this study was to measure the effect of substituting different levels of shrimp meal (SM) for soybean meal (SBM) in broiler diets. In Experiment 1, 0, 10, 20, 30, and 40% of the crude protein contributed by the SBM in broiler diets was substituted by crude protein from SM. In Experiment 2, 0, 60, 80, and 100% of the crude protein contributed by SBM in broiler diets was replaced...
