the aim of the current study was the screening the activity of 23 medicinal plants for decreasing the in vitro ruminal methane production, as well to and assess sheep ruminal in vitro fermentation parameters. 57.3 mg of each medicinal plants along with 142.7 mg control diet were weighted in 120 ml wheatons in 4 replicates. the samples were incubated using ruminal fluid obtained from 3 castrated...

Minerals and vitamins play an important role in animal nutrition with beneficial effects on animal reproductive performance. To investigate this issue, 44 Ghezel ewes weighing 55±  2 kg (Mean±SD) and 2-3 years old were randomly divided into groups (n=11), to investigate the effect of the selenium and vitamin E supplementation on blood hormones and metabolites and possible reproductive performan...

despite a shortage of animal feed in iran, cereal stubble is often underutilized due to agro-economic reasons. on the other hand, lambs fed with a conventional fattening ration deposit a considerable amount of fat; therefore, this experiment was conducted aimed at better utilization of cereal stubble and reducing the fat content of lamb carcasses. fat-tailed mehraban and ghezel ram lambs were p...

This study aims at investigating the effectiveness of utilizing barley as a Flushing ration with an energizing source and soybean meal-based diets as a Flushing ration with a protein source the sexual and breeding behaviors in Ghezel sheep. To this end, 36 three and half-year old ewes (51±1.5 kilograms) with the record of giving birth to two lambs and 6 three-year old (89±2.5 kilograms) rams we...

Castration of male animal's leads to a reduction in aggressive behavior, which animals will avoid wasting energy resulting to economic production of the animal, grows. It also reduces damage and bruising animals and increases normed meat producing at slaughter. In this study, 20 lambs Ghezel breed in four age groups, group 1: one month (n = 4), group 2: two months (n = 4) Group 3: three months ...

Evaluation of gastric emptying rate using nuclear scintigraphy as the gold standard method has been studied in various animals, but there is no report in suckling lambs. The aim of this study was to develop a nuclear scintigraphic method to visualize and measure abomasal emptying rate by estimation of scintigraphic half emptying time (T1/2) in the live neonatal lamb. Five healthy, female Irania...

Salicylic acid (SA) plays an important role in the regulation of plant ripening and responses to abiotic stresses. In this study, the protective effect of SA on cold stress-caused oxidative damage in grape (Vitis vinifera L.) bunches was investigated during cold storage.  Grape bunches treated with 2 mM SA and  stored at 0°C with 85-90% RH for 30 days. Samples were selected from each treatment ...
