the objective of this study was to determine the relationship between body weight (bw) and heart girth (hg) in sardi and timahdite sheep in order to develop a prediction equation of bw from hg. the data used for this study included 476 records on bw and hg (227 in sardi and 249 in timahdite) collected on males and females of different ages in 33 private farms. the bw and the hg averaged 34.8 ± ...

BACKGROUND The variability in the clinical or pathological presentation of transmissible spongiform encephalopathies (TSEs) in sheep, such as scrapie and bovine spongiform encephalopathy (BSE), has been attributed to prion protein genotype, strain, breed, clinical duration, dose, route and type of inoculum and the age at infection. The study aimed to describe the clinical signs in sheep infecte...

Santa Inês is the most common hair sheep breed in Brazil and probably has the highest genetic diversity among sheep breeds in this country. Successful breeding programs for Brazilian sheep breeds are not common for various reasons, including a lack of control of parentage in the flocks. We developed an allele frequency database for 23 STR loci for the Santa Inês breed based on 285 animals ...

background: the extensive consumption of milk anddairy products makes these foodstuffs targets for potentialadulteration with financial gains for unscrupulous producers.objectives: the aim of this study was using pcr assay todetect cow milk in labeled sheep milk, sheep yoghurt, andlighvan cheese (a traditional ripened cheese produced fromsheep's milk). methods: the assay utilized primers target...

Thirty-two groups of six sheep, classified into three breed categories according to their weight class (L: light, one breed (n=7); M: medium light, two breeds (n=10); H: heavy, three breeds (n=15)) were tested for antipredatory behaviour towards seven stimulus regimes. Tests were performed on 2-5-years-old ewes with lambs inside standardised and fenced home pastures. Stimulus regimes were: man ...

BACKGROUND The objective of this proteomics study was to identify proteins that changed expression as a result of copper challenge in the uniquely copper sensitive North Ronaldsay sheep and further, to compare those changes in expression with the more copper tolerant Cambridge breed. Such data gives us a proteome-centered perspective of the pathogenesis of copper-induced oxidative stress in thi...

This paper presents a new system architecture and test bed application implementation called Sheep Manager. Sheep Manager system uses NFC technology for the identification of sheep inside a flock as well as sensors for the real-time measurements and recording of raw milk extraction per ewe. All recorded information are then stored into the cloud. Authors also propose an algorithm for sheep bree...

Relevance. The article provides a justification for the use of sheep selection taking into account intra-breed type Prekos ewes in purebred breeding and crossing with producers semi-fine wool breeds Romney-Marsh Kuibyshevskaya to improve biological usefulness meat offspring. Methods : scientific economic experiment different options, productive Precos breed. Results. presents results study on i...

The melanocortin 1 receptor (MC1R) gene has been described as responsible for the black color in some breeds of sheep, but little is known about its function in many colored breeds, particularly those with a wide range of pigmentation phenotypes. The Brazilian Creole is a local breed of sheep from southern Brazil that has a wide variety of wool colors. We examined the MC1R gene (Extension locus...

background and aims: akabane disease causes epidemics of abortions, stillbirths and congenital malformations manifested as arthrogryposis and hydranencephaly or microanencephaly in sheep, goats and cattle. akabane virus replicates in arthropods and is transmitted by either mosquitoes or midges. outbreaks of the akabane virus have been reported from many countries in southeast asia, middle east,...
