The energy requirement of ewes increases during pregnancy. In late pregnancy, approximately 40% of the increase in heat production can be attributed to increases in heat production by nonreproductive tissues. The objective of this study was to determine the pattern of oxygen consumption by the portal-drained viscera (PDV) and liver during pregnancy to allow for an estimation of the extent to wh...
Long non-coding RNAs (lncRNAs) play important roles in almost all biological processes. However, there is little information on the effects of lncRNAs on ovulation and lambing rates. In the present study, we used high-throughput RNA sequencing to identify differentially expressed lncRNAs between the ovaries of multiparous (Mul) and uniparous (Uni) Anhui White goats. Among the 107,255,422 clean ...
An investigation on the occurrence of peri-parturient rise in trichostrongylid nematode egg output in breeding ewes was carried out on a Ranch in the semi-arid area of Kajiado District in Kenya during the period May 1999-April 2000. During the study, 20 ewes randomly selected from the breeding stock and 20 un-mated female yearlings were monitored for faecal strongyle egg output every 3 weeks. A...
characteristic of the udder, milk traits and their relationship were investigated in 32 awassi ewes raised in a commercial flock. commencing one month after lambing milk yield was recorded at monthly intervals until the ewes were dried. also, the udder traits were measured, including udder width, udder circumference, udder length, distance between teats and length and diameter of both teats. re...
Objective. The study aimed to characterize the reproductive performances and physical characteristics of Blackhead Somali indigenous sheep breeds. Methods. data from 460 were used for determination morphometric characterization while 110 male 150 females performance Results. Accordingly, about 86% have a white body with blackhead as dominant coat color 81% straight facial head profile. Dewlap w...
Estrus synchronization is a valuable management tool that has been employed in enhancing reproductive efficiency in ewes. This study was conducted to investigate the reproductive performance of ewes with short and long-term estrous synchronization programs accompanied by eCG or GnRH during the non-breeding season. A total of 48 Afshari ewes were randomly selected and divided into two groups. In...
Context Lamb loss and dyctocia are two major challenges in extensive farming systems. While visual observation can be impractical due to the large sizes of paddocks, number animals high labour cost, wearable sensors used monitor behaviour ewes as there might changes their activities prior lambing. This provides sufficient time for farm manager nurse those that at risk dyctocia. Aim The objectiv...
