The aim of this study is to estimate body weight from withers height, body length, and chest girth measurements by using Regression Tree (RT) Method. For this purpose, data were collected from 239 male sheep at yearling age (11-13 months) of five indigenous sheep breeds (Mengali (48), Balochi (48), Harnai (48), Beverigh (47) and Rakhshani (48)) reared in Balochistan, Pakistan. Bivariate relatio...

Chilota sheep is a typical animal population from Chiloé Archipelago in the south of Chile. First sheep were introduced in Chiloé in 1568 with Spanish conquerors. In 2010 Chilota sheep was recognized as the first original breed of Chile. Blood samples were obtained from 40 Chilota individuals from 40 flocks spread throughout Chiloé Archipelago. A maximum of one individual per flock were sampled...

Twelve Red Masai and 12 Dorper sheep aged between 6 and 9 months, were acquired from a fluke-free area and sheep of each breed divided into two equal groups of six. Each animal in one group of each breed was experimentally infected with 400 viable metacercariae of Fasciola gigantica. The other groups acted as uninfected controls. Blood samples were taken at weekly intervals for the determinatio...

AIM To study the major histocompatibility complex (MHC) Class II DRB1 gene polymorphism in Rohilkhandi goat using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and nucleotide sequencing techniques. MATERIALS AND METHODS DNA was isolated from 127 Rohilkhandi goats maintained at sheep and goat farm, Indian Veterinary Research Institute, Izatnagar, Bareilly. A 284...

litter size is one of the most important economical traits in sheep breeding industry. in addition to minor genes, litter size is under the influence of major genes. bone morphogenetic protein 15 (bmp-15), a member of the transforming growth factor beta (tgf-ß) superfamily, which is specifically expressed in oocytes, plays a dramatic role in sheep prolificacy. reported mutations in this gene ca...

Tibetan sheep, an indigenous breed, have a wide variety of phenotypes and a colorful coat, which make this breed an interesting model for evaluating the effects of coat-color gene mutations on this phenotypic trait. The agouti signaling protein (ASIP) gene is a positional candidate gene, as was inferred based on previous study. In our research, ASIP gene copy numbers in genomic DNA were detecte...

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 ± ...

Mycoplasma ovipneumoniae is an important respiratory pathogen of sheep across the world. In the present study nasal swab samples (n=778) were processed and 51isolates of M. ovipneumoniae were identified through biochemical tests and PCR. Difference in the isolation rate among districts (n=12), age groups (n=3), breads (n=6) was assessed. Similarly the isolate rate among healthy (n=513) and resp...
