The genotypes for calpastatin (CAST) and calpain (CAPN) loci were determined by PCR-RFLP and PCRSSCPmethods. Blood samples were collected from 200 pure-bred Zel sheep from Shirang’s Zel sheep Breeding Station located in south-west of Golestan, Iran. Extraction of genomic DNA was performed based on the modified salting out method. Based on results, two investigated loci were polymorphic an...

Continuous exposure to an aversive mixture was investigated as a means of maintaining aversion to vermeerbos in sheep subjected to the social influence of non-averted sheep. The use of an aversive mixture was based on a hypothesis that continuous exposure to an acceptable aversive mixture (containing both the aversive substance and the identification factors of vermeerbos mixed with maize meal)...

1. Photomicrographs of crystals of pure carbonmonoxide hemoglobin of the following species are presented; ox, sheep, hog, dog, turkey, rat, horse, chicken and guinea pig. Photomicrographs of the oxyhemoglobin crystals of the following species are also shown: ox, sheep, hog, dog, rat, horse and guinea pig. The crystals were formed from the pure protein by adding a suitable amount of ethyl alcoho...

Experiments have been performed on rabbits and sheep which demonstrate that pure carbon, in a flexible and filamentous form of great strength, can be used successfully to induce the formation of new tendons. A concept fundamentally different from that underlying the use of other artificial tendon replacements is involved, in which rapidly developing tendon-like tissue is induced to form around ...

Oxidized and reduced proteins were prepared from the ocular lenses of sheep, swine, chicken and fish (pike). The proteins were prepared under conditions designed to avoid denaturation and to produce relatively pure compounds. Serologic studies revealed that species specificity is demonstrable in the proteins from chicken and fish lenses, but in the more closely related species (swine and sheep)...

Australia's wild dogs include dingoes, introduced around 4000 years ago, feral domestic dogs and hybrids between the two. They are widely distributed throughout Australia. Predation and harassment of stock by wild dogs causes millions of dollars worth of losses to Australian sheep, cattle and goat producers each year. There are also opportunity costs in areas where sheep are not grazed because ...

Purpose – evaluate protective properties fleece depending on rank breeding differentiation sheep. determination ranks based regularities normal distribution animals in population herd repr...

Northrop and coworkers (1-3) believe that solubility studies constitute the most sensitive and reliable test for determining the homogeneity of proteins and have used them successfully as a test for purity of their crystalline enzyme preparations. Herriott, Desreux, and Northrop (4) were able to show that a number of pepsin solutions that appeared to be homogeneous in electrophoresis experiment...

A quantitative method of analysis for 2-aminoethylphosphonic acid (AEP) was developed using reverse-phase HPLC. The detection limit for AEP was 15 nM, and the detector response (peak area) was linear from AEP levels up to 100 microM (R = .99). Mean recovery of AEP added to strained ruminal fluid from faunated sheep was 98.2%. When AEP was added to a fermentation mixture at a concentration of 22...

ewe abortion and neonatal mortality are serious problems to sheep farmer. the objective of this paper was to report isolation of erysipelothrix rhusiopathiae from aborted fetuses in a flock in tehran, iran. abortion occurred in 10% of ewes in the flock. the fetuses were well developed and pinpoint, necrotic-like lesions were recorded on the placental cotyledons, whilst the inter -cotyledonary a...
