To study the calcium sensitivity of sheep hair follicle transglutaminase, which was reportedly calcium-independent [H. W. Harding and G.E. Rogers, Biochemistry, 11, 2858-2863 (1972)], the enzyme was purified from a homogenate of merino sheep hair follicles and its calcium dependence was examined. As a result of purification, two types of transglutaminases (DEAE-unabsorbed and absorbed transglutaminase, DU-TG and DA-TG, respectively) were obtained. The molecular mass of DU-TG was 77 and 82 kDa by SDS-PAGE and gel filtration, respectively, while that of DA-TG was 40 and 80 kDa. Each enzyme was obviously calcium dependent and contained (a) cysteine residue(s) in the active site, like other known mammalian transglutaminases. Maximum activation of DU-TG and DA-TG was observed at 1 and 0.1 mM CaCl2, respectively.

Ghrelin (GhRL) is an orexigenic hormone influenced by nutritional state. It plays a role in skin repair and diseases, though little information exists regarding its function in this organ. GhRL and its receptor were investigated in the skin of sheep under different feeding conditions to explore GhRL system presence and possible modifications due to diet.

Understanding species' dietary ecology and interspecific interactions is crucial for multi-species conservation planning. In Central Asia and the Himalayas, wolves have recolonized snow leopard habitats, raising considerable concern about resource competition between these apex predators. Using micro-histological analysis of prey species remains (e.

CRISPR/Cas9 technology has been widely utilized to enhance productive performance, increase disease resistance and generate medical models in livestock. The FecB allele in sheep is a mutation in the BMPRIB gene, recognized as the first major gene responsible for the high fecundity trait in sheep, leading to an increased ovulation rate in ewe. In this study, we employed CRISPR/Cas9-mediated homologous-directed repair (HDR) to introduce a defined point mutation (c.

This study aimed to evaluate the effects of sunflower cake (SFC) levels (0, 7, 14, 21, and 28% dry matter) in the diet for feedlot lambs on meat quality and its fatty acid profile. Forty crossbreed non castrated hair lambs were fed with experimental diets through 70 days when they were slaughtered and a Longissimus lumborum section were evaluated for physicochemical quality and fatty acid profile. There were no effects of SFC levels (P > 0.
