Effect of dietary methionine to crude protein ratio on performance of Ross 308 broiler chickens aged 22 to 42 days.

An experiment was conducted to determine the effect of dietary methionine to crude protein (CP) ratio on the performance of male Ross 308 broiler chickens aged 22 to 42 days. The diets were isocaloric and isonitrogenous but with different methionine-to-CP ratios. The diets, based on methionine to crude protein ratios, were M (0.

Effects of bee pollen inclusion on performance and carcass characteristics of broiler chickens.

This study was conducted to determine the effect of bee pollen (BP) inclusion on performance and carcass characteristics in broiler chickens. A total of 240 Ross 308 broiler chicks were allocated to 4 treatments (BP inclusion levels of 0, 4, 8, or 12 g/kg DM feed) in a randomized complete block design with sex as a block having 3 replicates with 10 chickens per replicate. After 21 d, the chickens remained in their treatment groups and fed standard grower diet.

The Influence of Different Amaranth Leaf Meal Inclusion Levels on Performance, Blood Profiles, and Gut Organ Characteristics of Ross 308 Broiler Chickens.

This study aimed to determine the effect of varying inclusion levels of amaranth leaf meal on the performance, blood profiles, and gut organ characteristics of Ross 308 broiler chickens. A total of 200, day-old, Ross 308 broiler chicks were randomly allocated to five dietary treatments in a complete randomized design, with each group having four replicates with ten chicks. Amaranth leaf meal (ALM) inclusion levels used in this study were 0, 5, 10, 15, and 20%.

Chemical Composition and Metabolomic Analysis of Grains Harvested at Different Stages.

This study aimed at investigating the impact of early versus normal grain harvesting on the chemical composition and secondary metabolites of species grown in South Africa. Mature harvested grain had higher ( < 0.05) DM, CF, NDF and ADF content compared to prematurely harvested grain.

Effect of dietary ascorbic acid supplementation level on productivity, mortality, and carcass characteristics of Venda chickens.

Two experiments were carried out to determine the effect of dietary ascorbic acid supplementation levels on productivity, carcass characteristics, and mortality of indigenous Venda chickens. The first experiment determined the effect of dietary ascorbic acid supplementation levels on productivity and mortality rate of 175 unsexed Venda chickens between 1 and 6 weeks old. The second experiment determined the effect of dietary ascorbic acid supplementation levels on productivity, carcass characteristics, and mortality rate of 140 female Venda chickens between 8 and 13 weeks old.
