متن کاملResponses of Dairy Cows to Supplemental Highly Digestible Rumen Undegradable Protein and Rumen-protected Forms of Methionine*
Metabolizable protein (MP) supply and amino acid balance in the intestine were manipulated through selection of highly digestible rumen-undegradable protein (RUP) sources and protected methionine (Met) supplementation. Four ruminallycannulated, multiparous Holstein cows averaging 193±13 days in milk were used in a 4×4 Latin square design to assess N utilization and milk production responses to ...
متن کاملeffects of varying crude protein and rumen undegradable protein on performance of holstein fresh cows
thirty multiparous holstein dairy cows with average body weights of 687±15 kg and body condition scores of 3.25±0.15 were allocated to 1 out of each 3 groups, immediately after parturition (dim=11) and in a completely randomized design. the first group was fed diet low in rumen undegradable protein (rup; 5.1% of dry matter), the second group fed with medium rup (7.2% of dry matter) while the th...
متن کاملEffects of Rumen Undegradable Protein on Productive Performance and N Balance of Holstein Cows in Early Post-Partum Period
Metabolizable protein (MP) supply and amino acid balance were manipulated through selection of highly digestible rumen-undegradable protein (RUP) sources. Effects on production efficiency and N utilization of early post-partum dairy cows were determined. Forty-two multiparous and 16 primiparous Holstein cows were assigned to the diets in a randomized complete block design immediately after part...
متن کاملBovine somatotropin and rumen-undegradable protein effects on skeletal growth in prepubertal dairy heifers.
The objectives of this study were to determine the effects of dietary rumen-undegradable protein (RUP) and bovine somatotropin (bST) during the period from weaning until puberty on body weight (BW) and skeletal growth rates and age at puberty. Fifty-one Holstein heifers at 90 d of age were randomly assigned to 4 treatment groups consisting of 0.1 mg/kg BW per day of bST and 2% added dietary RUP...
