this experiment was carried out to compare the effects of treated and untreated wheat straw with pleurotus florida on ewe feed intake, nutrient digestibility, and ewe body condition score (bcs) after parturition. thirty kermani ewes with an average weight of 48 ± 3.05 kg and about four years old were used in this experiment. synchronization of estrus in sheep has been achieved with the use of i...

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 ...

Late gestation supplementation of feed additives, such as rumen undegradable intake protein (RUIP), vitamin E, Zn, and chlortetracycline, has inconsistently improved ewe/lamb productivity. In 3 experiments, Western white-faced ewes were supplemented for at least 30 d during late gestation with 204 g/(ewe.d) on a DM basis of high (HS; 12.5% RUIP, 880 IU/kg of vitamin E, 176 mg/kg of Zn supplied ...

Reproductive performance of four, five and six-year old crossbred ewes representing six combinations ofFinnsheep (F), Dorset (D), Rambouillet (R), and White Face Western (WFW) breeding were evaluated when lambing in the winter (February-March, 1977) and in the fall (October-November, 1977). The six breed combinations represented were 3fsF, 5fsWFW; %F, 1f2D, %R; %F, %D, 1f2R; %F, %R; 1f2D, 1f2R;...

Ovine lymphosarcoma was diagnosed clinically in a 5-year-old Blackhead sheep in Kenya, and confirmed on blood smear, leukocyte count and macroscopic pathology. Four progeny of the ewe were examined. They were normal haematologically but 2 revealed bilaterally enlarged lymph nodes.

Reproductive performance and body weights of four and five-year old crossbred ewes representing five combinations of Finnsheep (F), Dorset (D) and Rambouillet (R) breeding were evaluated when lambing in the summer Oune-July, 1976). The five breed combinations represented were 1f2D, 1f2R; %D, %R; %F, 1f2D, %R; %F, %D, 1f2Rand %F, 3f4R. Breeding effectiveness of purebred and crossbred rams of Ham...
