In this study, effects of bovine somatotropin on libido, serum testosterone, hematological indices and certain serum biochemical metabolites in Sahiwal bulls were investigated. Six adult Sahiwal bulls with clinically normal reproductive tract and kept at the Semen Production Unit, Qadirabad, Sahiwal, Pakistan were used. These bulls were divided into two equal groups, i.e. treatment and control. Bulls of the treatment group were given bovine somatotropin (bST) at of 500 mg week...

Teddy is a highly proliferative goat breed, as females of this breed are famous for high twinning rates. Feed supplementation of olive oil has been shown to improve semen quality of goat bucks. In this study, the effects of feed supplementation with olive oil on serum testosterone, triiodothyronine (T3), thyroxine (T4) and some biochemical metabolites in Teddy goat bucks were investigated. For this purpose, 9 adult male goats, with clinically normal reproduc...

Medicago sativa plants are commonly used as green fodder. In this study, estrogen-like activity of ethanolic extract of Medicago sativa plants and its possible effects on serum biochemical metabolites in immature female rats were investigated. Crude extract of dried Medicago sativa plants was prepared in 90% ethanol using Soxhlet’s apparatus. Fifteen immature female rats were divided into 3 equal groups. Rats of groups A and B were given the extract at the dose of 250 (lo...

Buffalo is a major dairy animal in many countries of the world, including Pakistan. However, the productive and reproductive performance of this species is affected by many physiological problems such as anestrous. Therefore, this study was conducted to compare serum total cholesterol, thyroid hormone concentrations and haematological variables in cyclic and acyclic Nili-Ravi buffaloes. For this purpose, 60 adult Nili-Ravi buffaloes were divided into two equal groups i.e. cycl...
