The aims of this study were to identify the morphometric measurements and body weights Thin-tailed ewe, examine qualitative characteristics ewe close relationship between weight other measurements. This used 40 female Ewe aged under 1 year. method was purposive sampling. Parameters observed face length, ear chest circumference, width, depth, shoulder height, hip front leg hind tail length weigh...

Data were recorded for annual reproduction, wool traits and pre-joining live weight of between 992 (for staple strength) to approximately 1200 production records of Merino ewes over the period from 1997 to 2002. The resource population has been divergently selected from the same base since 1986, either for (H line) or against (L line) maternal multiple rearing ability. When expressed relative t...

O NE hundred seventy-nine ewe lambs from a three-breed polyallel cross involving the Willamette, Suffolk and Hampshire breeds were used to study the genetic aspects of fertility. Ewe birth weight, ewe weight at mating and fertility were analyzed in relation to heterosis, general combining ability, maternal effect, reciprocal differences, and the effects of a hormone treatment. Treatment consist...

The effect of level of dietary energy and protein intake on reproductive performance was studied in 110 Finn-cross ewe lambs and in 404 Finn-cross yearling ewes during late gestation. Nitrogen metabolism was studied in 26 ewe lambs and 23 yearling ewes. Increasing digestible energy and crude protein intake for ewe lambs and yearling ewes during late gestation increased (P<.05) ewe average daily...

Lifetime (5 yr) lamb production and wool production from 207 straightbred Targhee (T) and 474 1/4 Finn-1/4 Dorset-1/2 Targhee (FDT) crossbred ewes managed in a range or farm flock system were evaluated for ewe fertility, prolificacy, ewe fleece weight, and total lamb weight weaned per ewe exposed. Data included 2,620 ewe exposures, 2,384 parturitions, 4,638 lambs born, and 3,498 lambs weaned. E...

History: The ewe was a homebred breeding ewe on a farm in the Scottish Borders. The flock was composed of 530 ewes and 150 ewe hoggs which were housed from January to April. The ewes had been dosed for liver fluke in the previous autumn but not treated for worms, and had no worm treatment at lambing. Nematode parasites were effectively controlled by integrated evasive/anthelmintic strategies an...

The objective of the current study was to determine the effects of maternal MP intake in isocaloric diets during late gestation on female offspring growth from birth to breeding and measure reproductive performance of those offspring in their first breeding season. In yr 1, maternal dietary treatments were applied at d 100 of gestation, were similar in total energy, and contained 60MP1, 60% of ...
