This study was designed to identify genetically resistant animals to gastrointestinal nematode (GIN) infections using microsatellite polymorphisms of Ovar-DRB1 gene in Iranian Ghezel sheep breed lambs. In the present study 120 male Ghezel lambs were at 4 to 6 months of age randomly selected from six different sheep flocks in East Azerbaijan province (n=20 per flock). These lambs were naturally ...

Low birth weight (LBW) is associated with increased risk of adult cardiovascular disease and this association may be partly a consequence of early programming of the renin-angiotensin system (RAS). We investigated the effects of LBW on expression of molecules in the RAS and cardiac tissue remodeling. Left ventricular samples were collected from the hearts of 21 days old lambs that were born ave...

the objective of this study was to determine the effects of supplemented selenium (se) on plasma cortisol, red blood cell glutathione peroxidase activity (rbc gsh-px-1), concentration of immunoglobulin g (igg) and body weight in pneumonic suckling calves. ten holstein suckling male calves were randomly allocated to two groups and fed either unsupplemented milk (control) or with milk supplemente...

Neonatal changes in plasma free and total iodothyronines, cortisol, glucose and urea levels have been studied in 8 control (birthweight greater than or equal to 2.5 kg) and 16 hypotrophic lambs (birthweight less than 2.5 kg) receiving limited amounts of colostrum during the first 36 h of life and then fed ad libitum. During the period of colostrum feeding, plasma glucose levels were low in both...

The present study aimed to compare the expression levels of excitatory amino acid transporters (EAATs) and growth status of piglets weaned at 10‑20 days after birth with suckling piglets. A total of 40 hybrid piglets (Landrace x Large White x Duroc) born to 40 different sows, with similar body weight were selected for the present study. They were randomly divided into two groups (n=20 per group...

To examine the effect of diet on luteinizing hormone (LH) secretion, basal and luteinizing hormone releasing hormone (LHRH)-induced LH release was compared in intact or castrated-estradiol-17 beta implanted Finn-Dorset lambs. Ten to 12 wk old ram (n = 20) and ewe lambs (n = 20) were maintained under a 8L:16D photoperiod and fed for high (HG, 163 to 168 g/d) or low (LG, 76 to 103 g/d) rates of g...
