The present study aimed to estimate heritability, genetic and phenotypic correlations between body weight and body measurement traits in Iranian Makuei sheep. The used data were collected from 1989 to 2012 at Makuei Sheep Breeding Station in Maku (West Azarbayjan province). The data included body weight and five body measurement traits (body length (BL), heart girth (HG), withers height (WH), r...

Abstract Background In the present study, detection, characterization and virulence analysis of a field collected nucleopolyhedrovirus isolated from cotton leafworm, Spodoptera littoralis (Boisd.) (Lepidoptera: Noctuidae) was carried out. The obtained isolate, named SpliNPV-YW, diseased S. larvae in El-Menoufia governorate, Egypt. Results Transmission electron microscopy showed presence typical...

We estimated the genetic parameters related to feed intake (FI), feed efficiency traits (including feed conversion ratio (FCR) and residual feed intake (RFI) of digestible crude protein (DCP) and total digestible nutrients (TDN)), beef marbling score (BMS), melting point of fat (MP) and fatty acid composition. Fat and meat (Musculus trapezius) samples were taken from the carcasses of 863 Japane...

The purpose of this study was to evaluate the effect of adjusting for heterogeneous variances across breed groups on prediction of breeding values (PBV) of selected sires and on breed of sire effects. Data on weights at birth (BWT), 200 d (WW), and 365 d (YW) of purebred and crossbred calves from matings of Angus (A), Hereford (H), Polled Hereford, Charolais, Shorthorn, Simmental, Limousin, Mai...

The genetic diversity of cultivated crops has decreased continuously since the beginning 20th century, because gradual replacement genetically heterogeneous traditional varieties by new homogenous varieties, grown in monospecific stands. resulting agro-ecosystems are now considered as unsustainable. Increasing within-field crop using a mixture could increase sustainability these agro-ecosystems...

Data from 3,593 beef heifers and 4,079 of their steer paternal half-sibs were used to estimate genetic parameters of and among female growth and reproductive traits and male carcass traits. Estimates of heritability for adjusted 205-d weight, adjusted 365-d weight, age at puberty, calving rate, and calving difficulty measured on females were .16, .38, .47, .19, and .18, respectively; estimates ...

Pharmacokinetic and biodistribution studies were conducted in rats on a novel serine protease inhibitor, LEX 032, that was radiolabeled with 131I by the Bolton-Hunter reagent. LEX 032, a genetically engineered recombinant human nonglycosylated serpin, has been shown to have antiinflammatory properties in a number of animal models of inflammation and reperfusion injury. When 131I-LEX 032 was inj...

the objective of the current study was to estimate the genetic parameters for body weight traits at different ages in iran-black sheep. data collected during a 24-year period (1984-2008) on body weight were used to model the growth trajectory and estimate genetic parameters. studied traits were birth weight (bw), weaning weight at 3 months of age (ww), 6 months weight (6mw), 9 months weight (9m...
