Theexperiment was conducted to investigate the growth performance and feed conversion efficiency of crossbred heifer at different age level in Government Dairy Farm in Bogra, Bangladesh. Twelve female crossbred heifers were equally distributed (n=3) into four groups [Group A: (7±2 months), B: (12±2 months), C: (15±2 months) and D: (20±2 months)] according to age and fed concentrate mix, rice st...

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...

the aim of this study was to investigate the effect of feeding of  steeped barley grain with lactic acid (la) and citric acid (ca) on dry matter intake, feeding behavior, apparent nutrients digestibility, rumen ph and milk production. eight early lactating holstein cows in the second parities were used in 4×4 latin square change- over design. treatments  consisted of basis diet containing 1) dr...

Perennial ryegrass is the most abundant grass species in temperate climates. An increased herbage intake of dairy cows by breeding new cultivars could have a large potential impact on agriculture. The effects of cultivars on sward structure, nutritive value, physical characteristics and disease resistance of perennial ryegrass are discussed. Cultivar differences were found in several studies fo...

Intake and digestibility trials were conducted with sheep to evaluate the effect of adding various levels of a typical fibrous grass forage (neutral detergent fiber, NDF = 68%) to a high quality, low fiber (NDF = 22%) brassica forage. Four forage rape:orchardgrass hay diets (0, 40, 70, 100% rape content on a dry matter basis) were fed to groups of six Polled-Dorset crossbred growing wether lamb...

TWO methods of estimating pasture intake from total faecal output are discussed. Dry matter indigestibility co-efficients (apparent) are useful where the range of inter-species digestibility is relatively narrow in any one seasonal period. A relationship between total faecal nitrogen excretion and dry matter intake is illustrated and the biological principles upon which this type of relationshi...

the aim followed in the present study was to investigate the effects of different metabolizable protein (mp) levels on holstein cows, milk yield and composition, and as well on concentration of plasma metabolites in the cow,s early lactation. twenty - four holstein cows(bw 580±23, dim 30±7, parity 2.4±0.5) were randomly assigned to each one of the 4 dietary treatments containing 1) 10.60% (diet...

Sixteen steers (650 Ib) were used to determine the effects of corn moisture, protein concentration and monensin (Rumensin) on ration digestibility and nitrogen retention. The steers were placed in metabolism stalls and fed rations of high moisture corn (HMC) or dry rolled corn at two protein levels (9.3 and 12.3 percent) with two monensin levels (0 and 30 g per ton of feed). Monensin addition d...

Supplementation increased the total dry matter intake by 18.2-36.8 %. Supplements given alone or in combination had no effect on dry matter and organic matter digestibility of the diet. Crude protein digestibility was decreased with molasses supplementation. Crude fiber digestibility was not affected by baker’s yeast supplementation but decreased with other supplements. The digestibility of nit...

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...
