Growth And Development Of Two Broiler Strains With Low Protein And Crystalline Amino Acid Supplemented Diets, Chaoyang Li
Growth And Development Of Two Broiler Strains With Low Protein And Crystalline Amino Acid Supplemented Diets, Chaoyang Li
LSU Master's Theses
The objective of this research was to compare the growth performance of broilers from two commercial breeds with control, low protein and low protein supplemented with crystalline amino acids diets. This was a randomized block design, and identical experiments were conducted on successively in two years. In each experiment, day-old chicks, Ross 708 broilers and Cobb 405 broilers, were randomly assigned into three dietary treatments: 1) positive control, 2) low crude protein (LP), and 3) LP + crystalline amino acids (CAA). A three phase feeding program was used. Feed and water were provided ad-libitum. On d 12, 19, 26, 33, …

The objective of this study was to evaluate Bacillus megaterium, Bacillus licheniformis, and Bacillus subtilis, as probiotic strains compared to Bacitracin Methylene Disalicylate (BMD) 50 as the antibiotic growth promotor, supplemented in commercial broiler rations and their influences on performance, yield, and intestinal microbiota. This trial was completed as a randomized-block design with 4,800 birds split into 96, 5’x10’ pens, and randomly assigned to one of eight treatment groups. The birds were placed at a stocking density of 1.00 ft2/bird, (50 birds/pen), and reared on used pine shaving for 55 days. Throughout the study, bird …
