(1) Background. Merino is a worldwide sheep breed well known for the quality and quantity of its wool. If there no doubt that it originates from Mediterranean Basin human selection took place in southern Spain, populations potentially contributed to building this are matter debate. Here, we tested whether Moroccan settled on North Atlantic coast, Beni Ahsen, could be good candidate, given thick...

20 Presence of Neospora caninum DNA was detected in the brain and spinal cord of an adult 21 Merino sheep suspected of dying with non-suppurative meningoencephalitis due to 22 neosporosis. As this was the first known occurrence of disease in sheep in Australia caused 23

The heritability of carcass quality traits and the genetic correlations between wool production and these carcass quality traits were estimated on 1216 Merino rams. The results showed that carcass quality traits are moderately heritable but pH appears to be lowly heritable. Yellowness and redness of L. dorsi had very low heritability estimate. Moderate negative genetic relationships were found ...

The evaluation of sheep feed intake (FI) in efficiency tests is expensive. Decreasing the test period could be a resource-saving tool by reducing cost evaluating each animal and allowing to greater number animals per year. For this reason, objective research was explore residual (RFI) models decreasing duration. Data collected from 286 Australian Merino three performed trials, consisted 56 days...

The primary selection objective in the South African Mutton Merino is meat production, while wool plays a secondary role. The Merino, on the other hand is selected for wool production. Respectively 20 and 23 of each genetic different type of ewes were used in a 15-week indoor study to quantify the influence of nutrient intake on certain production traits when fed at different levels of their re...

Context Internal parasites are estimated to cost the Australian sheep industry AUD436 million per annum (p.a.). Aims To assess effects of parasitism in flocks producing prime lambs 500–700 mm p.a rainfall. area Victoria. Methods Ewes on two farms that followed ‘best practice’ gastrointestinal parasite control programs (BP) and did not (regionally typical, TYP) were compared. Separate cohorts ew...

The allele frequencies of 10 microsatellite loci previously described for sheep as BM1314, BM6526, OarFCB128, OarHH64, OarCP20, OarHH47, OarFCB48, OarHH35, OarHH72 and BM2508 were estimated for the Uruguayan flocks. A representative sample of 101 individuals composed by the two predominant breeds (76% Corriedale and 24% Australian Merino) was used. The sample did not show a significant tendency...

This study investigated the impact of variation in Australian sheep breeding values (ASBVs) for yearling eye muscle depth (YEMD) within Merino and Poll Dorset sires on intermediary metabolism of progeny. Specifically, the change in the blood concentrations of lactate, non-esterified fatty acids (NEFA) and glucose in response to administration of an exogenous dose of adrenaline was studied. The ...
