چکیده
Introduction Among the different factors accounting for the better utilization of poor forages by goats, compared with sheep, urea recycling and better mastication during ingestion have been reported (Masson et al, 1986; Morand-Fehr et al, 1987). Our purpose was to measure the particle size in the alimentary bolus and to indirectly assess urea recycling, by chemical analysis of alimentary bolus.

Evaluation of the nutritive value of wild almond seed (Amygdalus scoparia) and its effect on performance, milk fatty acid composition and antioxidant activity in lactating goats
A total of 21 dairy goats in mid lactation were randomly assigned to three experimental diets in a completely randomized design. The diets contained 0, 3, or 6% WAS, and consisted of 45% forage and 55% concentrates. Milk fat and the ratio of milk fat to milk protein were significantly lower in goats fed diets containing 6% WAS (P≤0.01). Digestibility of crude fat was higher, and that of neutral...
متن کاملThe impact of a bacterial inoculant on chemical composition, aerobic stability and in sacco degradability of corn silage and the subsequent performance of dairy cows
The aim of this study was to investigate the effect of bacterial inoculation on the fermentation and aerobic stability of corn silage and on the dry matter degradability and milk composition when fed to sheep or cows. Four male sheep were selected to measure dry matter degradability of uninoculated (UCS) and inoculated (ICS) corn silage. Milk composition was measured for 22 Holstein cows, separ...

The aim of this study was to evaluate the effect of fat supplementation for enhancing milk conjugated linoleic acid (CLA) in early lactation without affecting ruminal fermentation. 24 Holstein dairy cows were assigned to a completely randomized design employing a 2 × 4 factorial arrangement. Factors were particle size (15 and 25 mm) and two different sources of alfalfa supplemented with and wit...

The experiment was carried out using 200 Ross 308 broiler chickens in a completely randomized design with 5 treatment and 4 replicates. The experimental diets were consisted of a control free hulls diet and four diets containing 0.75 or 1.5 percent rice hulls with particle sizes of less than 1 mm or between 1-2 mm. The performance traits were determined through 42 d experimental period and car...
متن کاملComparison of Leptospira interrogans infection in the goats and sheep
Background: Most leptospiral infections in sheep and goat are asymptomatic but may result in high fever, abortion, stillbirth, agalactiae. There is a different foraging behavior between sheep and goat that may cause the different prevalence of Leptospira interrogans infection in sheep and goats. OBJECTIVES: The purpose of the present study was to compare the prevalence of L. interrogans antibod...
