investigation of the grazing behavior of grazing animals on the rangeland is one of the basic necessities of grazing management in different climatic regions. the current study with the aim of exploring the grazing behavior of makuyi sheep breed was conducted in the mountainous rangelands of kelid daghi of jolfa as representative rangelands for makuyi sheep breed dispersion in east azerbayjan p...

This study estimated the magnitude of sexual dimorphism in a relict sheep from Catalunya (NE Spain), called Fardasca,using geometric morphometric techniques. For these analyses, a total of 18 skull specimens (2 adult males and 16 females) were studied. Our results suggest that the breed is not cranially dimorphic, so sex determination using landmarks described here as criteria is likely to yiel...

the archaeological evidence suggests that iran has been one of the first origins of sheep domestication in the world. this study aims to investigate the genetic diversity of indigenous iranian sheep breeds using mitochondrial dna (mtdna) and to explore the evolutionary history of sheep domestication in iran. single nucleotide polymorphism (snp) markers in the control region of mtdna were used t...

The apolipoprotein A-V (APOA5) gene is a candidate that plays an important role in carcass characteristics and lamb quality. This study aimed to association polymorphism of the APOA5 with quality sheep. breed sheep were used 100 consisting Thin Tailed Sheep (TTS) (n=55), Compass Agrinac (CAS) (n=10), Garut (GS) (n=18), Composite (GCS) (n=8), Barbados cross (BCS) (n=9). Identification was perfor...

With this investigation, the anatomy of bulbus oculi was studied in 12 Akkaraman sheep. The oculi’s specific morphological features breed were introduced study. In border cornea and scle-ra, limbus ended at point where it entered under sclera. eyes examined, existence rima cornealis sclera not observed. Based on observations made, center thinner com-parison with its periphery. sheep, determined...

Objective: The aim of this study was ultrasonographic findings and technique ofthe liver in the Lori breed sheep.Design: Descriptive study.Animals: 10 clinically healthy, female sheep.Procedures: Ultrasound examination of liver performed from the caudal aspect of13th rib to the 7th intercostals spaces (ICS). The possibility of liver imaging fromeach ICS, distance between the position of liver i...

The milk somatic cell count (MSCC) forms the basis of abnormal milk control programs world wide for goats, cows and sheep. To better understand factors that contribute to elevations in MSCC, the effects of stage of lactation, parity, breed and state/area in the United States (US) on MSCC were examined. Least squares means were calculated on composite milk somatic cell scores from 26,607 goats, ...

The objective of this cross-sectional study was to detect the presence maedi visna virus (MVV) infections in sheep three counties southwestern Croatia: Istria County, Primorje-Gorski Kotar County and Lika-Senj estimate influence geographical location, breed, age gender as risk factors on prevalence rate. A total 460 randomly selected were tested using a commercially available ID Screen® MVV/CAE...

in this study genetic diversity of eight iranian sheep breeds including; lori bakhtiari, makuei, moghani, taleshi, shal, zandi, naeini and kalakui was studied by using aflp method. a total of 309 individuals were analysed that produced 121 clear polymorphic bands. the average of heterozygosity within breed (hs) was high and equal to 0.2795± 0.0255. also, the average heterozygosity between breed...

Toxicity studies of 0,0-diethyl-0-(2- isoprophyl-6-methyl-4-pyrimidinyl) phosphorothioate (DiazinonR) was carried out in the Balami breed sheep. The agent administered orally daily for one week at rate 20, 25 and 30mg/kg body weight to groups dose produced transient clinical signs Diazinon inhibited plasma red blood cell cholinesterase activity. intensity inhibition more with occurred as from d...
