sixteen rams (mean age: 13 mo; mean live weight: 40.0 ± 2.4 kg) were randomly allotted to four dietary treatments in a completely randomized design (4 rams per treatment). diets (dry matter basis) contained 65% concentrate and 35% alfalfa hay (control diet, t1), 35% wheat straw (t2), 35% barley straw (t3) or 35% maize straw (t4). total-tract apparent digestibility for dry matter, organic matter...

this experiment was carried out to study the effects of sainfoin (onobrychis viciifolia) as tannin source and different level of forage: concentrate ratio on digestibility, blood parameters, ruminal fermentation, milk yield and milk composition in milking ewes. therefore, eight lori milking ewes were alocated to factorial experiment base on the 4×4 replicated latin square design. four total mix...

an experiment was carried out to evaluate how interactions between forage to concentrate ratio and dietary crude protein level may alter nitrogen efficiency and ut-b expression in growing baluchi male lambs. four baluchi male lambs [30 ± 2 kg bw] were used in a 4 × 4 latin square design with 28-d periods and a 2 × 2 factorial arrangement of dietary treatments. the treatments fed forage: concent...

Four Baluchi male lambs [30 ± 2 kg BW] were used in a 4 × 4 latin square design with 28-d periods and a 2 × 2 factorial arrangement of dietary treatments. The treatments fed forage: concent...

This study evaluated the effects of dilution rate and forage-to-concentrate ratio on gas production by rumen microbes. Continuous cultures were used to monitor methane production at three liquid dilution rates (3.2, 6.3, or 12.5%/h) and three forage-to-concentrate ratios (70:30, 50:50, or 30:70). Filtered ruminal contents were allowed 6 d of adaptation to diets followed by 7 d of data collectio...

The objective was to establish effects of feed presentation time and dietary forage to concentrate ratio on circadian postprandial rhythms of feed intake in lactating cows. Four multiparous and four primiparous Holstein cows were fed in a 4 × 4 Latin square design (with a 2 × 2 factorial arrangement of treatments) a higher (HC, forage to concentrate ratio = 38.5:61.5) or a lower (LC, forage to ...

We conducted two experiments to evaluate the effects of corn supplementation, source of corn, and corn particle size on performance and nutrient utilization of lactating dairy cows. In experiment 1, treatments were 1) direct-cut grass-legume forage without supplement, 2) direct-cut forage plus 10 kg DM of ground dry shelled corn-based concentrate, and 3) direct-cut forage plus 10 kg DM of coars...

The objective of this study was to determine the effect of different forage to concentrate ratios for fattening of Lohi lambs. For this purpose, 75 lambs were randomly divided into 3 groups A, B and C, with 25 lambs in each group. Berseem fodder was supplemented with concentrate at different ratios (forage to concentrate) as 75:25, 50:50 and 25:75 and fed to groups A, B and C, respectively for ...
