(Co)variance components and genetic parameters for test day ewe body weight of Lori-Bakhtiari sheep were estimated using a random regression model (RRM). The data consisted of 22153 individual body weight records, obtained from 1994 ewes (progeny of 205 sires and 1010 dams) between 371 and 3416 days of age, collected from the flock stud of Lori-Bakhtiari Sheep Breeding Station in Shahrekord, Ir...

Tkáãiková a. , M. R. , Bhide I . Mikula: Asymmetric PCR-SSCP: a Useful Tool for Detection of OLA-DRB1(MHC class II) Gene Polymorphism in Slovak Improved Valachian Sheep. Acta Vet. Brno 2005, 74: 275-278. Detection of OLA-DBR1 (exon 2) gene polymorphism is presented in the paper. Rapid and inexpensive polymorphism detection method, namely, single stranded conformation polymorphism (SSCP) was ass...

the poly morphism of 4 micro satellite loci (bms1350, lgb, ilsts45, bms1915) associated with functional traits were evaluated for detecting the diversity level in baluchi breed of sheep. one hundred eighty five blood samples were collected from sheep herd in abbas-abad breeding station. dna extraction was performed using guanidinethiocyanate silica gel method. gene fragments of micro satellites...

The fecundity in sheep has been much interested for producers due to its economical importance. Growth differentiation factor 9 (GDF9) is an autosomal gene with over dominance effect for twosingle nucleotide polymorphisms(SNPs), which resulted in sterility in homozygote mutant ewes and additive effect for three SNPs, without showing sterility event. In the present study, DNA was extracted from ...

BACKGROUND It has been questioned if the old native Norwegian sheep breed, Old Norse Sheep (also called Norwegian Feral Sheep), normally distributed on coastal areas where ticks are abundant, is more protected against tick-borne infections than other Norwegian breeds due to a continuously high selection pressure on pasture. The aim of the present study was to test this hypothesis in an experime...

An unknown disease outbreak was reported in four villages of Salem district viz., Aranganoor, Athigaripatty, Avadathur and Amanikondalanpatty in Tamil Nadu State and subsequent mortality among the Mecheri breed of sheep and Tellichery breed of goat was investigated .The clinical signs observed among the animals were high fever, anorexia, profuse diarrhoea with bilateral mucopurulent oculonasal ...

Species-specific differences in genes encoding type II GnRH receptor indicate that a functional hepta-helical receptor is produced in monkeys but not in rodents, cows, chimpanzees, or humans. To further investigate the extent of evolutionary differences, we sequenced the type II GnRH receptor gene from wild-type Soay sheep. The gene was isolated by long-distance PCR using primers to PEX11beta a...
