The aim of this study was to observe the dynamic expression of osteopontin, type I collagen, and osteocalcin genes during the differentiation of bone marrow mesenchymal stem cells (BMSCs) into osteoblasts and confirm whether BMSCs can differentiate and mature into osteoblasts. A healthy, 2-month-old Altay tailed sheep was obtained, and 10 mL bone marrow was extracted from the posterior superior...

Background and Aim: Healthy meat production is an important aspect of increasing sheep productivity. This study aimed to examine the influence protected kapok seed oil (KSO) in combination with choline chloride (CC) on feed utilization, lipid status, performance thin-tailed sheep. Materials Methods: Thirty male (approximately 6 months old, average body weight 12.59 ± 1.48 kg) were divided into ...

The Nordic and Baltic countries and North-western Russia have >20 old native sheep breeds. These together with recently synthesized breeds and local populations of international breeds make up the northern European sheep diversity. Changes in agriculture threaten to erode genetic diversity in sheep. Molecular genetic variation was assessed to understand genetic diversity in northern European sh...

The accurate identification of sheep is crucial for breeding, behavioral research, food quality tracking, and disease prevention on modern farms. As a result the time-consuming, expensive, unreliable problems traditional sheep-identification methods, relevant studies have built face recognition models to recognize through facial images. However, existing such as high computational costs, large ...

BACKGROUND: Fat-tailed sheep breeds have a  unique  ability  to  tolerate  periods  of  negative  energy  balance  due to seasonal changes in feed availability. This ability is attributed to presence  of  fat-tail  as  a  body  energy  reserve, however the exact underlying  mechanisms  controlling  the  response  of adipose  tissue  depots  to variations in energy balance in fat-tailed breeds a...

Three bald eagles (Haliaeetus leucocephalus), a red-tailed hawk (Buteo jamaicensis), and two coyotes (Canis latrans) found in a field in north-central Kansas (USA) in December 1992 were poisoned by flowable carbofuran (Furadan 4F) placed on sheep (Ovis aries) carcasses to kill coyotes. The carbofuran was placed on the carcasses in October 1992, but the coyotes and raptors apparently were killed...

Development of mice expressing either ovine (Tg338) or cervid (TgElk) prion protein (PrP) have aided in characterization of scrapie and chronic wasting disease (CWD), respectively. Experimental inoculation of sheep with CWD prions has demonstrated the potential for interspecies transmission but, infection with CWD versus classical scrapie prions may be difficult to differentiate using validated...
