performance of broiler chicks fed cottonseed and soybean meal based diets and determination of the optimum supplemental lysine in starts period
an experiment was conducted to determine the optimal level of supplemental lysine in a corn-soybean mealcottonseed meal starter diet. three hundred and sixty day-old male chicks (ross 308) were used in a completely randomized design (15 birds per each pen). a basal diet was formulated to meet or exceed nrc (1994) recommendations except for lysine. graded levels of supplemental lysine (0, 0.1, 0...
متن کاملdetermination of maximal singularity free zones in the workspace of parallel manipulator
due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...
15 صفحه اولThe Effect of Formulation Diets Based on Digestible Amino Acids and Lysine Levels on Carcass and Chemical Composition of Broiler
This study was conducted to evaluate the carcass yield, abdominal fat deposition and chemical compositions of thigh and breast muscles of male Arian broilers fed three different lysine levels of 1) high lysine (110% NRC), 2) standard level suggested by National Research Council (NRC) and 3) low lysine (90% NRC) based on two expression ways of amino acid contents of feedstuffs, as total amino ac...
متن کاملInteractions Between Levels of Methionine and Lysine in Broiler Diets Changed at Typical Industry Intervals
This study was conducted to evaluate the use of Met and Lys levels in excess of NRC (1994) recommendations adapted to feeding periods more consistent with current industry applications. Diets were formulated to provide a minimum of 110% of NRC recommended levels for amino acids other than Met and Lys. Aliquots of the diets were fortified with DL-methionine and Lysine HCl to provide three levels...
متن کاملEffect of betaine and arginine in lysine-deficient diets on growth, carcass traits, and pork quality.
Forty entire male pigs from a commercial crossbreed (Duroc × Large White × Landrace) were used to investigate the individual or combined effects of betaine and Arg supplementation in Lys-deficient diets on growth performance, carcass traits, and pork quality. Pigs with 59.9 ± 1.65 kg BW were randomly assigned to 1 of 5 dietary treatments ( = 8). The 5 dietary treatments were normal Lys and CP d...
