Coagulase-negative staphylococci (CNS) are among the major causes of subclinical mastitis in dairy ewe flocks. This has a financially significant impact on sector and consumer health. The determination bacterial count, particularly CNS, is critical terms quantity quality ovine milk. Thus, purpose this study was to quantify CNS count udder surface raw milk samples ewe, addition identifying strai...

Abstract Rendering male lambs short-scrotum interferes with testicular development and thermoregulation, has been proposed as a management tool to control reproduction. This study evaluated at the effect of timing procedure (birth or weaning) on growth rate, testis size, libido, ejaculate characteristics carcass traits in landrace hair sheep lambs. April- (n = 31) August-born 23) Barbados Black...

this study was evaluated some strategies and determined the suitable selection index for afshari sheep using simulated data. the relative importance of traits was determined based on the estimated economic values and consequently, the most benefit traits were applied to selection indexes construction. the interest indexes were different combination of traits including ewe body weight (ebw), ann...

In this study 71 head of conceiving ewe and their progeny (91 head) from the flock of Lori-Bakhtiari sheep (360 head), in Sholi Station were randomly selected to determine the relationship between the immunoglobulin (IgG) concentration in the ewe's serum and colostrum, and lamb's serum. Ewe blood sample, colostrum of ewe and blood of the lamb was taken 2 weeks before parturition, 1 to 8 hours a...

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...

The objective of the current pilot study was to evaluate the reproductive performance and health indicators in Dorper, White Dorper, and Tsigai breed ewes managed semi-intensively under European temperate conditions. A total of 544 ewe-year units were observed, with ewes (ranging from 1.5 to 8 years of age) managed under identical rearing conditions for a period of two consecutive production cy...
