This study was conducted on a commercial New Zealand sheep farm in order to compare the cure rates of merino sheep infected with footrot. Infected sheep were treated with either lincomycin/spectinomycin combination (Linco-Spectin soluble powder, Pfizer Animal Health) or tilmicosin (Micotil 300 Injection, ELANCO) antibiotics. A flock of 3000 mixed age merino ewes had their feet inspected by the ...

x The problem received the title of 'Buridan's sheep.' The biological code was taken from a young merino sheep, by the Casparo-Karpov method, at a moment when the sheep was between two feeding troughs full of mixed fodder. This code, along with additional data about sheep in general, was fed into CODD. The machine was required: a) to predict which trough the merino would choose, and b) to give ...

Chlamydia pecorum is a significant pathogen of domestic livestock and wildlife. We have developed a C. pecorum-specific multilocus sequence analysis (MLSA) scheme to examine the genetic diversity of and relationships between Australian sheep, cattle, and koala isolates. An MLSA of seven concatenated housekeeping gene fragments was performed using 35 isolates, including 18 livestock isolates (11...

The relationships between testis size, hormone secretion and sperm production were studied during the spring (December) and autumn (May) in rams of two breeds with different breeding seasons and body weights (Corriedale and Australian Merino) maintained on native pastures and under natural photoperiods in Uruguay. Blood samples were collected at 20-min intervals during a 260-360-min period in 1...

The Small Tailed Han is a prolific local sheep breed in China. The bone morphogenetic protein receptor IB (BMPR-IB) gene, which affects the fecundity of Booroola Merino sheep, and the bone morphogenetic protein 15 (BMP-15) gene, which affects the fecundity of Inverdale, Hanna, Belclare, Cambridge, and Lacaune sheep, were studied as candidate genes associated with the prolificacy of Small Tailed...

THE AIM OF THIS STUDY WAS TO INVESTIGATE THE GENETIC DIVERSITY WITHIN AND AMONG THREE BREEDS OF SHEEP: Corriedale, Merino and Creole. Sheep from the three breeds (Merino n = 110, Corriedale n = 108 and Creole n = 10) were genotyped using the Illumina Ovine SNP50 beadchip(®). Genetic diversity was evaluated by comparing the minor allele frequency (MAF) among breeds. Population structure and gene...

Sheep farmers are actively seeking unbiased information on the performance of sheep breeds and bloodlines within breeds to help improve their overall profitability. To help answer this question the Elmore Field Days Inc ran a comparison to determine the merit of five ewe genotypes for prime lamb and wool production from 2009 to 2014. Each of the five genotypes were represented by 42 ewes random...

In Italy, the crisis of the wool industry triggered the necessity to reconvert the two traditional Merino-derived breeds, Gentile di Puglia and Sopravissana, to meat production, by creating the Merinizzata Italiana. The aim of the present study was to assess the genetic diversity of these three Italian Merino-derived (IMd) breeds by examining the molecular information encoded in the maternally-...
