In this article, live weight and body size parameters of hybrid lambs obtained from inbreeding F2 sheep with Hisar native breed genotypes were higher than those pure lambs. These results showed that improvement selection traits using rams is great scientific practical value. The the was 5.62 kg at birth, females 5.17 kg, respectively. group I, 0.45 or 8.7%, 0.34 7.2% purebred heifers. However, ...

BACKGROUND The demand for healthy, lean and consistent meat products containing low saturated fatty acid content and high quality polyunsaturated fatty acids (PUFA), especially long-chain (≥C20) omega-3 PUFA, has increased in recent times. Fat deposition is altered by both the genetic background and dietary supplements, and this study aimed to assess the effect of dietary Spirulina supplementat...

The main purpose of this study was to evaluate the influence of the photoperiod on the seminal traits of crossbreed wool-producing rams throughout on year period. For the effect of photoperiod two periods were considered: decreasing daylight length (summer and autumn) and increasing daylight length (winter and spring). For the study 5 Baluchi × Moghani (BL×MG) and 5 Arkharmerino × Moghani (AM×M...

Image processing technique was used to compare udder morphological characteristics in two Iranian crossbred sheep populations including Ghezel-Arkhamerino, Moghani-Arkharmerino and a pure one that was Ghezel ewes. In addition, the resulted measurements were applied as independent variables for estimation of daily milk yield by regression models. Udder height of Ghezel was higher than Ghezel-Ark...

The objective was to evaluate the performance and ingestive behavior of grazing sheep in finishing stage, with supplementation period water restriction. Fifteen male crossbred were used continuous pasture Massai grass supplied supplement formulated 18% crude protein three levels (0.0; 0.3 0.6% body weight), individually. Bromatological fodder production analyses performed, as well foliar mass p...

The objective of this work was to evaluate the performance, carcass traits and economic indicators Santa Inês lambs their crossings finished in feedlot. Thirty whole (10 Inês, 10 ½ Dorper + ¾ ¼ Inês) were used, with 115 days age initial live weight 20.07 kg. kept for 60 receiving sorghum silage concentrate, after which they slaughtered. showed higher dry matter intake water intake, greater dail...

Background: The winter chill in temperate zones of the country affects animal production. It is understood that during cold animals have to maintain their body temperature through increased heat production, thus energy partitioning towards production compromised. Since sheep has a thick wooly coat insulates from harsh ambient temperatures, hence present study was undertaken assess impact housin...

The present study was conducted to compare sperm motion characteristics of adult Malpura and Bharat Merino rams by the computer-aided sperm analysis (CASA) technique. Malpura is a hardy native sheep breed of the semi-arid tropical environment and Bharat Merino is a crossbred evolved in the same environment by crossing native sheep with exotic rams. Semen was collected from 8 donor rams of each ...
