The effect of rumen protected methionine (RPMet) on milk composition of lactating Cashmere Rayeni goat
BACKGROUND: Methionine has been suggested as the firstlimitingamino acid for milk production in ruminants. It is importanthow to increase milk protein yield and milk fat in dairy ruminants.OBJECTIVES: This study was set to investigate the effect of rumenprotected methionine (RPMet) on milk composition of lactatingCashmere Rayeni goats. METHODS: 40 healthy singletonCashmere Rayeni goats about 3 ...
متن کاملeffect of reducing metabolizable protein with added rumen-protected lysine and methionine on the performance of the pregnant afshari ewes
the aim of this study was to investigate the effect of reducing metabolizable protein with rumen-protected lysine and methionine in diet during the last 5 weeks of gestation on performance and blood parameters of afshari ewes and lambs. twenty five mature (once lambing) ewes in a unbalanced complete randomized design fed with diets containing low metabolizable protein but containing rumen-prote...
متن کاملEffect of feeding rumen-protected methionine on productive and reproductive performance of dairy cows
The objectives of this study were to evaluate the effects of daily top-dressing (individually feeding on the top of the total mixed ration) with rumen-protected methionine (RPM) from 30 ± 3 until 126 ± 3 Days in milk on productive and reproductive performance in lactating dairy cows. A total of 309 lactating dairy Holstein cows (138 primiparous and 171 multiparous) were randomly assigned to tre...
متن کاملEffect of rumen-protected methionine, lysine or both on milk production and plasma amino acids of high-yielding dairy cows
The objective of this study was to determine the effect of supplemental lysine (Lys), methionine (Met) or both amino acids added in the form of rumen-protected (RP) tablets with copolymer coating to a diet of dairy cows on yield and composition of milk and concentration of plasma amino acids (AA). The experiment was carried out on four high-yielding lactating Holstein cows with average milk pro...
متن کاملEffect of Supplementing Rumen-protected Methionine on Serum Biochemistry of Iranian Rayeni Cashmere Goat
Objective: This study was set to investigate whether the administration of ruminally protected methionine as a supplement on lactating goats could have been some toxic effects on serum biochemistry. Methods: Thirty adult (3-4 years old) female Rayeni goats were randomly divided into two groups as follow: control and treatment groups each contain thirty goats. Goats in both groups were fed on th...
