Female reproductive trait were studied in four pure breeds (the Finnsheep, Suffolk, Targhee and Minnesota 100), the F1 crosses between Finnsheep rams and females of the other three breeds and F2 and backcross ewes. Precocity of sexual development, defined as the percentage of ewe lambs lambing at 12 months of age, was measured in 709 ewe lambs in 4 years. Lambing and weaning rates were measured...
A diallel cross involving three Moroccan breeds of sheep (Sardi, Beni Guil, and D'man) was analyzed by least squares procedures. A total of 456 ewes were mated to 22 rams and this resulted in 528 lambs born from 412 ewes. D'man ewes had by far the highest general performance as measured by total weight of lamb weaned, even though the average live weight per lamb was the lowest for the three bre...
The effects of melengestrol acetate (MGA) and P.G. 600 on ewe fertility outside the natural breeding season were evaluated. Rambouillet ewes were assigned to one of four groups: (1) control (C; n=92); (2) PG600 (n=86); (3) MGA (n=99); and (4) MGA+PG600 (n=92). A pellet with or without MGA (0.3mg/ewe/d) was fed at 0.15kg/ewe/d for 7d. On the last day of pellet feeding, ewes were given either sal...
This study approaches the interrelation patterns between composition of milk and whey, curd yield, chromaticity, syneresis, technological quality Manchega sheep using multivariate factor analysis. In addition, effect main husbandry components (flock, prolificacy, season year, stage lactation, parity) on common latent factors that define pattern variation was assessed. For this purpose, 1,200 in...
evaluation of gastric emptying rate using nuclear scintigraphy as the gold standard method has been studied in various animals, but there is no report in suckling lambs. the aim of this study was to develop a nuclear scintigraphic method to visualize and measure abomasal emptying rate by estimation of scintigraphic half emptying time (t1/2) in the live neonatal lamb. five healthy, female irania...
Nutritional and metabolic parameters of ewe lambs fed yeast in the diet containing fibrolytic enzyme
This study aimed to evaluate the dry matter digestibility, intake and metabolic profile of ewe lambs fed active or inactive yeasts in diet containing fibrolytic enzyme. Twenty crossbred animals with an average weight 33.4kg age six months were distributed a completely randomized design. The treatments consisted yeasts: Control (no yeast), Milk Sacc X® (active Active Flora® yeast + yeast) Rumen ...
In many sheep production operations in the Midwestern and Eastern U.S., lambs are managed for maximum body weight gain and fed high-energy diets continuously from shortly after birth until they are marketed as slaughter lambs. Flock owners will replace 20 to 25% of the ewes in their flock each year with ewe lambs raised in their flock or purchased from other producers. Since all lambs in a floc...
