Although host-encoded prion protein (PrP(C)) expression in ovine PBMCs and prion infectivity in scrapie-infected sheep blood have been demonstrated, such studies have not been reported in goats. Therefore, this study characterized cell-surface expression of PrP(C) on PBMC subsets derived from normal goats and sheep, by flow cytometry, and determined prion infectivity in blood from a scrapie-inf...
palatability includes plants physical and chemical property that encourages an animal selecta plant for grazing. this study is an attempt for intruducing an indicator for determining thepalatability of rangeland plants. to do this, the relationship between palatability and foragequality of rangeland plants in karsanak rangelands of the chaharmahal-va-bakhtiari provincewas studied. first, plant ...
We attempted an oral rush desensitization with mixed cow and sheep milk in a 6-year-old boy who had had adverse reactions to cow and goat milks. Skin prick tests and specific immunoglobulin (Ig) E to cow, sheep and goat milks were positive. The double-blind, placebo-controlled food challenge with cow milk was positive too. He underwent a 12-day sublingual-oral desensitization treatment with mix...
UNLABELLED Antigenic and genetic typing of pestiviruses isolated from Indian sheep and goats was carried out. Testing of 1777 sheep and 1026 goat blood samples collected between 2004 and 2008 resulted in isolation of twelve pestiviruses, seven from sheep and five from goats. All of them were antigenically typed as bovine viral diarrhea virus 1 (BVDV-1). Both the partial 5ʹ-UTR and entire non-st...
A medium-density linkage map of the ovine genome has been developed. Marker data for 550 new loci were generated and merged with the previous sheep linkage map. The new map comprises 1093 markers representing 1062 unique loci (941 anonymous loci, 121 genes) and spans 3500 cM (sex-averaged) for the autosomes and 132 cM (female) on the X chromosome. There is an average spacing of 3.4 cM between a...
The intraperitoneal route was explored both as an alternative to the intravenous route for the vaccination of sheep and goat kids against heartwater and for the administration of an antibiotic to animals suffering from the disease. Only 8 (57%) of the 14 adult sheep, and none of the 7 goat kids, were found to be immune after intraperitoneal vaccination with infective blood. However, this route ...
ICAR Technical Series No 3 The development of the Dorper sheep and the Improved Boer Goat are undoubtedly two of the most successful long-term livestock programmes in South Africa. The Dorper is a composite mutton sheep breed developed through crossing an indigenous breed with a British mutton breed and the Improved Boer Goat was developed using a breeding strategy based largely on selection fo...
Counts were made of the numbers of spermatozoa in the Fallopian tubes of ewes 24 hr after mating or after insemination with either sheep or goat semen. Spermatozoa were recovered from all five mated ewes (10/10 tubes), from all eight ewes inseminated with sheep semen (13/15 tubes) and from four of eight ewes inseminated with goat semen (7/16 tubes). The calculated mean numbers of spermatozoa pe...
To investigate Brucella infection in cattle, sheep, goat, reindeer and yak in Mongolia, serological reactions of Brucella-infected and -vaccinated domestic animals were compared by the agar gel immunodiffusion (AGID) test with a polysaccharide (poly-B) of the B. Abortus strain S-19. The sensitivity and specificity were compared with conventional serological tests that are commonly used in Mongo...
The origin of horse, dog, cat, bovine, sheep, porcine, and goat meat was determined by the polymerase chain reaction (PCR) technique, using species-specific primers. Test mixtures of meat were prepared by adding 5%, 2.5%, 1%, 0.5%, and 0.1% levels of pork, horse, cat, or dog meat to beef, sheep, and goat meat. Samples taken from those combinations were analyzed by PCR for species determination....
