The effect of rumen protected methionine (RPMet) on milk composition of lactating Cashmere Rayeni goat
نویسندگان
چکیده مقاله:
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 to 4 years of age, at the first day oflactation, were randomly divided into 2 equal control andexperimental groups. The experimental group was supplementedwith 5 gr/day RPMet for 60 days. Milk samples of 2 groups weretaken on 30th and 60th days of the study. Milk protein, milk fat, milklactose, and milk Solids-not-Fat (SNF) were determined usingautomatic analyzer. The results were statistically evaluated withSPSS. RESULTS: The supplementation with RPMet did not effectall of the above mentioned parameters during the 60 days of theexperiment (p>0.05), except for the milk fat percentage of theexperimental group which showed significant increase after 60days (p

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...
متن کاملEffect of feeding different sources of rumen-protected methionine on milk production and N-utilization in lactating dairy cows.
Objectives of this study were to quantify production responses of lactating dairy cows to supplying absorbable Met as isopropyl-2-hydroxy-4-(methylthio)-butanoic acid (HMBi), or rumen-protected Met (RPM, Smartamine M; Adisseo, Alpharetta, GA) fed with or without 2-hydroxy-4-(methylthio)-butanoic acid (HMB), and to determine whether Met supplementation will allow the feeding of reduced dietary c...
متن کاملEffect of supplementing rumen-protected methionine on production and nitrogen excretion in lactating dairy cows.
Two 4 x 4 Latin square trials (4-wk periods; 16 wk total) were conducted to see whether supplementing rumen-protected Met (RPM; fed as Mepron) would allow feeding less crude protein (CP), thereby reducing urinary N excretion, but without losing production. In trial 1, 24 Holsteins were fed 4 diets as total mixed rations containing [dry matter (DM) basis]: 18.6% CP and 0 g of RPM/d; 17.3% CP and...
متن کاملEffect of alfalfa silage storage structure and rumen-protected methionine on production in lactating dairy cows.
The objective of this study was to determine whether production and nutrient utilization differed when lactating cows were fed diets based on 1 of 3 sources of alfalfa silage (AS) and whether performance was altered by feeding rumen-protected Met (RPM; fed as Mepron). Thirty-six lactating Holstein cows were blocked by parity and days in milk, then assigned to a randomized complete block design ...
