Effect of supplemental rumen-protected methionine on reproduction and production of Awassi ewes

نویسندگان

چکیده

The effect of rumen-protected methionine (RPM) was investigated in Awassi ewes (0, 3 or 5 g/head/d, n = 20) on reproductive and productive performance (initial body weight [BW] 70.9 − 71.8 kg, years). Supplementation started with the flushing feeding regime (at breeding time) lasted for 42 d. RPM reused during last 60 d pregnancy first lactation. increased (p < .05) progesterone concentration a higher lambing rate at 5RPM level. number lambs born each ewe exposed to ram also 3RPM 5RPM. Methionine levels plasma were greater mainly Birth weights regardless Contrary this, weaning gain reduced addition. did not affect milk production lactation energy corrected feed ratio. However, protein content level while fat decreased. Regardless addition, casein .05). At all levels, fatty acid profile minor. It can be concluded that supplementing might valuable tool enhance their season.

Effect 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...

Effect 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 ...
