the objective of this study was to evaluate the effects of supplementation of different level protein diets with rumen protected methionine and lysine on performance and ruminal parameters in holstein dairy cows when in their early lactation. twenty one dairy cows in their early lactations were assigned to three treatments in a randomized block design experiment of a 35-d duration period. diets...

  Shirbot (Barbus grypus) as a species with high potential for aquaculture development recently propagated artificially in South Iran Aquaculture Research Center to extend the species diversity in polyculture system. To provide an effective economic diet for this species 9 experimental diets containing three crude protein levels (250, 300, and 350 g kg -1) and three metabolizable energy levels ...

the aim of this study was to compare the effects of two levels of crude protein using poultry by-product meals (pbpm) fed during late gestation on the performance, blood metabolites, and colostrum composition of holstein dairy cows. sixteen multiparous cows 26±6 d before expected calving were assigned randomly to two treatments containing 1) 14% and 2) 16% crude protein. the cow’s bcs was 3.56 ...

1. An experiment was conducted to test the independent and combined effects of high dietary calcium and protein concentrations on the induction of visceral gout in growing birds of a layer strain. 2. One hundred and sixty healthy birds were randomly divided into 4 groups at 35 d of age. The different groups were given 4 diets containing normal or high concentrations of dietary calcium or crude ...

An experiment was conducted to determine apparent ileal digestibility of crude protein (CP) and amino acids (AA) and digestible CP and AA of fish meal (FM) in 21-d-old broiler chickens using the regression technique. Four diets containing 0, 1, 2, and 3% FM in place of cornstarch were formulated with FM as the sole contributor of CP and AAs in the sequential diets. Eighty 14-d-old broiler chick...

Two experiments were conducted to evaluate the effect of betaine supplementation of finishing diets on growth performance and carcass characteristics of swine. Experiment 1 included 288 pigs in a 2 x 2 x 3 factorial arrangement of treatments consisting of barrows and gilts of two genetic populations fed diets with 1.25 g/kg supplemental betaine from either 83 or 104 kg to 116 kg and control pig...
