Sunflower Meal and Enzyme Supplementation in Diets of Broilers from 21 to 42 Days of Age
The objective of this study was to evaluate the performance of male broiler chickens in the period from 21 to 42 days of age fed diets with increasing levels of sunflower meal (SM) supplemented with an enzyme complex (EC). A total of 1920 animals of the Cobb strain were distributed in a randomized block design in a 4 × 3 factorial arrangement (four SM levels and three enzymes utilization types)...
متن کاملBioavailability of different dietary supplemental methionine sources in animals.
Dietary methionine is indispensable for animal maintenance, growth and development. L-methionine (L-Met), and its synthetic forms DL-methionine (DL-Met) and 2-hydroxy-4 (methylthio) butanoic acid (HMTBA) are common supplemental methionine sources in animal diets. There are different characteristics for cellular absorption, transport, metabolism and bio-efficiency between these three dietary met...

متن کاملUse of chemical characteristics to predict the relative bioavailability of supplemental organic manganese sources for broilers.
Twelve organic Mn sources and MnSO4 were evaluated by polarographic analysis and via solubility in buffers (pH 5 and 2) and deionized water. Fractions from solubility tests were evaluated by gel filtration chromatography for structural integrity. Organic Mn sources included five Mn methionine complexes (Mn Met A to Mn Met E), two Mn proteinates (Mn Pro A and Mn Pro B), and five Mn amino acids (...
متن کاملDigestible lysine requirements of male broilers from 1 to 42 days of age reassessed
Three experiments were conducted separately to estimate the digestible Lys (dig. Lys) requirements of Cobb × Cobb 500 male broilers using different statistical models. For each experiment, 1,200 chicks were housed in 48 floor pens in a completely randomized design with 6 treatments and 8 replicates. Broilers were fed diets with increasing dig. Lys levels from 1 to 12 d (Exp. 1), from 12 to 28 d...
