Vitamin A (retinoic acid) is known to be an adipogenic factor influencing both in vitro and in vivo cell development. This study aimed to determine its effect on lamb adipose tissue development during the early phase of postnatal development until 100 d of age. Male lambs (n = 24) of the Rasa Aragonesa breed were used. At birth, lambs were assigned to 1 of 2 experimental groups: 1) the control ...

Formulated zinc methionyl bST (sometribove, 50, 100, or 150 mg) was administered as a single treatment once every 2 wk or as two equal treatments once/week to evaluate the efficacy of prolonged release delivery of bovine somatotropin (bST) in finishing lambs. Feed conversion during the 6-wk treatment period was improved 9 and 19% in lambs that received treatments once and twice/2 wk, respective...

The study was conducted on 20 Polish Merino ram-lambs divided into two groups: experimental (E) and control (C), each of 10 animals. From birth all the lambs were maintained with their dams and then weaned at the age of 8 weeks, placed in individual straw-bedded pens and fattened individually with a granulated concentrate mixture until reaching a mean body weight of 31.8 kg. During fattening ea...

introduction: excessive olivo-cerebellar burst-firing occurs during harmaline-induced tremor. we hypothesized that antiglutamatergic agents would suppress harmaline tremor. from this point of view, the aim of current study was to investigate the effects of riluzole on harmaline-induced tremor in rat. material and methods: four groups of wistar rats weighing 80–100 g were injected with harmaline...

The current study was carried out to investigate the effect of Long-term betaine supplementation on performance Saidi lambs during growing period. Twenty-four local Egyptian (Saidi) with 7 months age and average body weight 25 ±1.36 kg were used. Lambs allocated one three experimental treatments eight replicates (control group, low (LBS); supplemented 1500 mg /kg concentrate mixture or high (HB...

An experiment was conducted to determine the effects of unsaturated fatty acids supplementation on growth performance and carcass characteristics of finishing lambs. Thirty-two finishing Afshari lambs (initial weigh 58 ± 5 kg and 8 mo age) were used in a completely randomized design with 4 treatments (slaughtered in time series) and 8 lambs/treatment for the final 30 d before slaughter. The sla...
