abstract

published data on the effects of essential oils (eo) on in vivo nutrient digestibility in sheep are contradictory. in 2 experiments, the effect of thymol and carvacrol on nutrient digestibility was studied in sheep fed with high (70%) or low (52%) concentrate diets, using incomplete latin square designs. the essential oils were mixed with the concentrate portion of the diet at the rate of 0.0, 0.3, or 0.6 g per kg dry matter (dm) diet. supplementation of thymol had no significant effect on digestibility of dry matter (dm), organic matter (om), crude protein (cp) and acid detergent fiber (adf). the main effect of thymol on neutral detergent fiber  (ndf) and ether extract (ee) digestibility and on nitrogen balance (nb) was significant (p

Effects of fiber source on apparent digestibility and ruminal fermentation parameters in sheep fed high-concentrate diets

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...

Effect of Dietary Crude Protein Level on UT-B Expression and Nitrogen Efficiency in Growing Baluchi Male Lambs Fed Low or High Concentrate Diets

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...

Effects of supplemental phytase on nutrient digestibility and performance of sows fed diets with high or low native phytase activity

Two experiments were conducted to examine the influence of addition of microbial phytase to diets differing in native phytase content, on the performance of sows and digestibility of nutrients. Barley and wheat grains relatively poor in native phytase used in Experiment 1 mixtures were replaced by triticale and rye (rich in this enzyme) in Experiment 2 diets. There were 3 groups in each experim...

effect of neutral detergent soluble carbohydrate source and addition roasted canola seed on growth performance and nutrient digestibility of lambs fed high concentrate diets

in order to investigate the effect of partial replacement of barley starch with beet pulp soluble fiber with or without roasted canola seed on apparent nutrient digestibility, dry matter intake, daily weight gain, feed conversion ratio and rumenal ph 24 arabian male lambs were used for 84 days in a completely randomized design with a 2×2 factorial arrangement. treatments had no significant effe...
