Sixty Ghezel ewes (age 3.5 years) were used to study the effect of different nitrogenous supplements in flushing ration on reproductive performance. Experimental treatments were divided in five groups: group A: urea; group B: soybean meal (SBM); group C: corn gluten meal (CGM); group D: barley grain and group E: control or basal diet (no flushing). The four flushing rations had nearly the same ...
data on 361 lambs of mehraban (n=90), ghezel (n=92), ghezel × mehraban (n=87), and mehraban × ghezel (n=92, sire breed listed first) were used to estimate individual heterosisfor lamb growth. the obtained results demonstrated that lambs of purebreds of ghezel and mehraban showed the highest and the lowest birth weight, respectively (p
Extended Abstract Introduction and Objective: The advantages of using milk replacer include proper growth of lambs, prevention of consumption of bodily reserves of mother ewes, preparation of ewes for the next calving period, reduction of calving distance, increase of twinning and reduction of costs. The aim of this study was to investigate the effect of milk replacer on Performance, blood par...
the effect of crossbreeding between ghezel and mehraban on growth performance and carcass characteristics was studied for two consecutive years using 162 purebred and crossbred lambs. the four groups of lambs involved in the study were purebred mehraban (mm), purebred ghezel (gg), crossbred ghezel ram×mehraban ewe (gm) and crossbred mehraban ram×ghezel ewe (mg). the lambs were fed with grazing ...
The aim of this study was investigation of various levels of vitamin E in Tris extender on semen characteristics of Ghezel rams in pre and post freezing conditions. Semen was collected from six healthy and mature rams with average 55±5 Kg body weight by electro ejaculator. High quality samples were mixed and diluted in Tris extender after apply different concentration of vitamin E. Treatments w...

Two groups of 24 Hampshire and 26 Suffolk purebred ewes each were used to study effects of cohabitation with cyclic white-faced (WF) ewes on estrous activity in June. Ewes lambed in January, February and March and had been isolated from mature rams since the previous fall breeding. From June 1 to July 2, treated (T) ewes were exposed to vasectomized rams and to 65 WF ewes; control (C) ewes were...
In late pregnancy, energy deficits in ewes can induce a metabolic imbalance, which often results in pregnancy toxaemia. This metabolic disorder is characterised by hypoglycaemia, hyperketonaemia, an increase in plasma concentrations of free fatty acids and by fatty infiltration in the liver. The purpose of the present study was to identify alterations in lipid and triglyceride-rich lipoprotein ...
AntunoviC, Z., J. novoSELEC, H. SAuERWEin, M. SpERAndA, M. vEGARA and v. pAviC, 2011. Blood metabolic profile and some of hormones concentration in ewes during different physiological status. Bulg. J. Agric. Sci., 17: 687-695 The aim of this paper is to determine the influence of physiological status on blood metabolic profile and some of hormones concentration in the blood of ewes. Investigati...
The objective of this study was to compare weight and quality of fleeces of different F1 ewe types produced from breeds with a broad range of fleece types. Weights of 629 fleeces produced during 1988 through 1991 from F1 ewes that were daughters of Suffolk and Targhee dams and Finnsheep, Combo-6, Booroola Merino, St. Croix, and Barbados sires were recorded. Staple length was measured on the mid...
