the current experiment was carried out to investigate the possible effects of replacing alfalfa by dried de-oiled savory (satureja khuzistanica; dds) at the levels of 0, 25, 50, 75 and 100 percent in finishing diets of mehraban lambs on kinetics of gas production in vitro. the experimental diets contained 20% alfalfa and 80% of concentrate on dry matter basis. replacing alfalfa by dds had no si...

The reproductive factor (R = final egg density at 55 days / 5,000, initial egg density) of Meloidogyne chitwoodi race 2 (alfalfa race) on 46 crop cultivars ranged from 0 to 130. The reproductive efficiency of M. chitwoodi race 1 (non-alfalfa race) and M. chitwoodi race 2 was compared on selected crop cultivars. The basic difference between the two races lay in their differential reproduction on...

Alfalfa (Medicago sativa L.) is an important legume forage crop with great economic value. However, as the growth of alfalfa is seriously affected by an inadequate supply of water, drought is probably the major abiotic environmental factor that most severely affects alfalfa production worldwide. In an effort to enhance alfalfa drought tolerance, we transformed the Arabidopsis Enhanced Drought T...

Twenty-four multiparous dairy cows (eight with ruminal cannulae) were blocked by days in milk and assigned to six balanced 4 x 4 Latin squares with 21-d periods. The four diets, formulated from alfalfa silage plus a concentrate mix based on ground high moisture ear corn, contained (dry matter basis): 1) 20% concentrate, 80% alfalfa silage (24% nonfiber carbohydrate; NFC), 2) 35% concentrate, 65...

. eight holstein cows in early lactating stage were used in a 4×4 change-over design within 4 periods of 21-d to determine the effects of alfalfa hay particle size and soybean oil supplementation on intake, digestibility, ruminal and blood metabolites, chewing activity, milk yield and compositions. four total mixed rations containing 20, 20 and 60% corn silage, alfalfa hay and concentrate respe...

The objective of this study was to determine the effects of a homolactic acid inoculant on ensiling characteristics and nutritive value of high dry matter (DM) alfalfa. The ensiling characteristics were determined by ensiling inoculated and untreated alfalfa haylage in mini-silos for 0, 2, 4, 8, 16 and 45 days. Two lactating cows fitted with ruminal fistulas were used to determine ruminal degra...

We evaluated the effect of forage quality on response of cattle to supplementation with cooked molasses blocks. In Exp. 1, 175 heifers had ad libitum access to prairie hay (5.2% CP, DM basis). Treatments were a 2 x 3 factorial: supplementation with 0 or 1.96 kg/d of alfalfa DM, and supplementation with no cooked molasses block or with a low-protein or a high-protein cooked molasses block (14.4 ...

Objective: Evaluate the productive performance of rabbits fed alfalfa- and white clover-based diets.Design/ methodology/ approach: Rabbits can consume high-fiber diets. Therefore,this study evaluated a diet (Diet 1) an alfalfa-based 2).The experiment was carried out during Fall-Winter season 2018. This used111 (males females), weaned at 31 days age. Diets were randomlyassigned to 20 cages, four...

The increased production and use of nanoparticles (NPs) has generated concerns about their impact on living organisms. In this study, nCu, bulk Cu, nCuO, bulk CuO, Cu(OH)2 (CuPRO 2005, Kocide 3000), and CuCl2 were exposed for 15 days to 10 days-old hydroponically grown lettuce (Lactuca sativa) and alfalfa (Medicago sativa). Each compound was applied at 0, 5, 10, and 20 mg L(-1). At harvest, we ...

abstract in this study 36 holstein bulls (initial bw of 345±61 kg) were randomly assigned to 6 dietary treatments, following a 3×2 factorial arrangement, with 3 concentrate level of fish oil (0, 1 and 2.1% of dm) and 2 levels of alfalfa hay versus corn silage (10 and 20 % of alfalfa hay forage) to investigate the effects of fish oil supplementation and ratio of alfalfa hay and corn silage in di...
