Measure of energy related biochemical metabolites changes during peri-partum period in Makouei breed sheep.

Makouei sheep is one of the famous breeds in Iran which is reared in Azerbaijan province for their meat, milk and wool. Fifty clinically healthy Makouei ewes were selected to study the variations in energy-related blood metabolites during peri-partum period. Blood was collected from Jugular vein from each sheep on day 7 before the expected lambing time, day of parturition and also day 7 postpartum to determine total protein, albumin, urea, cholesterol, glucose, triglyceride, β-hydroxybutyrate (BHB) and non- esterified fatty acid (NEFA) levels.

Genetic analysis and the estimates of genetic and phenotypic correlation of growth rates, Kleiber ratios, and fat-tail dimensions with birth to yearling live body weight traits in Makuie sheep.

Genetic parameter estimates of growth rates, Kleiber ratios, and fat-tail dimensions were aimed using 22, 253 records at the present study. The studied traits were average daily gain from birth to weaning, average daily gain from 9 months of age to yearling, Kleiber ratio from birth to weaning, Kleiber ratio from 9 months of age to yearling, fat-tail length, fat-tail width, and fat-tail thickness. Each trait was fitted by four different animal models, which are differentiated by including or excluding maternal effects.

The relationship of GH and LEP gene polymorphisms with fat-tail measurements (fat-tail dimensions) in fat-tailed Makooei breed of Iranian sheep.

Background: The present study was designed to investigate the association of GH and LEP genes' single-nucleotide polymorphisms with fat-tail measurements (fat-tail dimensions) in Makooei sheep.

Materials And Methods: DNA was extracted from whole blood samples collected from 100 sheep. Polymerase chain reaction (PCR) products were subjected to single-strand conformation polymorphism (SSCP) denaturation and polyacrylamide gel electrophoresis.
