Abstract:
... Branched chain fatty acids (BCFAs) are associated with ‘mutton flavour’ found in cooked sheep meat aroma. Three BCFAs, 4-methyloctanoic (MOA), 4-ethyloctanoic (EOA) and 4-methylnonanoic (MNA) acids, have been implicated as the main compounds responsible for ‘mutton flavour’. Animal age can also contribute to increasing BCFA concentration. Heptadecanoic acid (C17:0 FA) also increases with animal ag ...

Abstract:
... Vaccines and genetic resistance offer potential future alternatives to the exclusive use of anthelmintics to control gastrointestinal nematodes (GIN). Here, a Teladorsagia circumcincta prototype vaccine was administered to two sheep breeds which differ in their relative levels of resistance to infection with GIN. Vaccination of the more susceptible Canaria Sheep (CS) breed induced significant redu ...

This study explored the regenerative osteogenic response in the distal femur of sheep using scaffolds having stiffness values within, and above and below, the range of trabecular bone apparent modulus. Scaffolds 3D-printed from stiff titanium and compliant polyamide were implanted into a cylindrical metaphyseal defect 15 × 15 mm. After six weeks, bone ingrowth varied between 7 and 21% of the scaff ...

Abstract:
... Improving the survival of twin-born lambs is a high priority for the Australian sheep industry. Higher mob sizes at lambing have been suggested to decrease the survival of twin-born lambs. However, our recent work indicated that this effect may not occur when feed-on-offer (FOO) exceeds 2400 kg DM/ha during the lambing period. Increasing mob size at lambing when FOO is limited may exacerbate the r ...

The molecular and population genetic status of Mongolian native sheep (MNS) is not well understood mostly due to a lack of material and trained personnel. In this study, we initially examined the genetic diversity, populati ...
