early weanling and rearing of lambs on milk replacer is an important act to increasing flock productivity. two experiments were carried out to compare the voluntary intake and nutrients digestibility ewe milk and commercial milk replacer and their feeding effects on the growth rate, feed intake and feed efficiency of suckling lambs. in experiment 1, eight lambs (two 4-lamb groups) at 31 to 34 d...

Individual growth and feed intake of 36 Angus, 27 Polled Hereford and 30 Holstein steers were determined from 365 to 560 kg live weight. One-half of the cattle in each breed were fed a diet based on high-moisture ear corn and the other one-half were fed a diet based on corn silage. Within each breed X diet group, half of the cattle were implanted with zeranol. Cattle fed the high-moisture ear c...

this experiment was designed to evaluate the effect of phenolic components of scrophularia striata powder on feed intake, digestion and fermentation, rumination kinetic and rumen ecosystem in lori-bakhtiari sheep. in this experiment, 12 six months old lambs and average weight 30±1.5 kg were fed with 0 (control), 3 and 6 percent scrophularia striata for one month. feed intake, digestibility, rum...

Four breed types with 12 cows/breed-type (Hereford x Angus, AHx; Charolais and Angus and Charolais x Hereford, Cx; Jersey x Angus, Jersey x Hereford, Jx and Simmental x Angus, Simmental x Hereford, Sx) were used to estimate nutrient requirements for zero daily weight change. Four nonpregnant, nonlactating cows of each breed type were assigned to one of three feeding levels [90 kcal metabolizabl...

this experiment was conducted to evaluate the effect of camelthorn (alhagi sp.) as a foraghe in the diet of balouchi sheep (during the last two months of gestation and two months of lactation) where 72 ewes in a completely randomized design with three treatments (diets) and four replications were used. experimental diets were : 1) wheat straw 50%, alfalfa hay 30% and barley grain 20%, as contro...

The objective was to evaluate different levels of crambe cake (CC) protein (0, 250, 500, 750 and 1000 g/kg DM) as a replacement for soybean meal in diets lambs their effect on performance, carcass traits meat quality. Forty not castrated crossbred male lambs, weighing 20 ± 3.45 kg, were settled completely randomized design with eight replicates per treatment. Final body weight (BW), dry matter ...

the effect of ephedrine at 0 (e0c0, n = 10), 8 (e8c0, n = 10) and 10 (e10c0, n = 10) mg per kg metabolic body weight or mixture of ephedrine/caffeine, at doses of 8 mg ephedrine/80 mg caffeine (e8c80, n = 10), or 10 mg ephedrine/100 mg caffeine (e10c100, n = 7), per kg metabolic body weight on body composition of feedlot mehraban ram lambs (8-month-old) was studied. the lambs were fed for 95 da...

Background: Fat supplementation in ruminants ration often adversely affect dry matter intake (DMI), rumen fermentation and nutrients digestion. Basal diet ingredients is an undeniable determinant of ruminants responses including performance, chewing behaviour and nutrient digestibility to fat supplementation. Objective: Current study was conducted to evaluate the effect of Fish oil (FO) supplem...
