in order to identify the segre qtl affecting growth traits on the end region of chromosome 18 in a lori-bakhtiari sheep population, 162 animals from 5 paternal half-sib families were taken to be studied. phenotypic data included records of birth weight (bwt), weight at one month of age (w1), weaning weight (wwt), weight at six months of age (w6), chest circumference (gi6), body length (lg6), wi...

Astrocytoma as one of the most common central nervous system (CNS) tumors is rarely reported in veterinary literature. A 7-year-old Persian Lori-Bakhtiari ewe was presented to the clinic with a two months history of progressive blindness, nystagmus to the right, bilaterally decreased pupillary reflexes, head pressing and paddling. At necropsy, a whitish well-circumscribed mass with dimensions o...

ninety six pairs of adrenal glands from lori – bakhtiari sheep and goat, aged 6 month to 1 year and 1 – 1.5 year from borujen abattoir were collected. after collecting the glands and weighting them, some parameters such as: length, wide and thickness of left and right side by caliper device were measured. in histological studies, after tissue preparation and staining with h&e;, cortical zones a...

BACKGROUND: Fat-tailed sheep breeds have a  unique  ability  to  tolerate  periods  of  negative  energy  balance  due to seasonal changes in feed availability. This ability is attributed to presence  of  fat-tail  as  a  body  energy  reserve, however the exact underlying  mechanisms  controlling  the  response  of adipose  tissue  depots  to variations in energy balance in fat-tailed breeds a...

The aim of this study was to perform molecular and bioinformatics analysis of IGFBP2 gene promoter in association with some economic traits in indigenous Makuee (MS) and Lori-Bakhtiari (LB) breeds. DNA was extracted from blood samples of 120 MS and 200 LB and a 297 bp fragment from the upstream sequences of studied gene was amplified and genotyped by single-strand conformational polymo...

Background: Fatty acid mobilization and inflammatory response of adipose tissues vary in various depots, hence the response of fat-tailed and thin-tailed sheep breeds to different energy balances was hypothesized to be different due to differences in proportion and metabolism of various adipose depots in these breeds which may affect whole body insulin sensitivity. Objective: Current study aime...

this study was carried out to investigate the effect of selection on the reduction of fat-tail size in lori-bakhtiari lambs. the study lasted for five years at the development and breeding center of lori-bakhtiari sheep station. estimation of fat-tail weight, using external fat-tail dimensions was obtained from regression procedure at 6 month age. soft tissue depth at the point 12 cm from the m...

the data set employed in this study was comprised of a number of 6,800 records of lamb’s longevity and their survival rate, collected from 1989 through 2009, from the lori-bakhtiari experimental flock at the shooli station in shahrekord, iran. the data were analyzed using linear models and proportional hazard models with weibull function. these models included fixed factors and direct additive ...
