Goats (Capra hircus) are one of the oldest species of domesticated animals. Native Korean goats are a particularly interesting group, as they are indigenous to the area and were raised in the Korean peninsula almost 2,000 years ago. Although they have a small body size and produce low volumes of milk and meat, they are quite resistant to lumbar paralysis. Our study aimed to reveal the distinct ...

Genetic correlations between purebred Duroc (DU), Large White (LW) and Landrace (LR) pigs and their crossbreds LW×LR, LR×LW, DU×(LW×LR) and DU×(LR×LW) were estimated for production and reproduction traits. Performance test and litter records from Government pig breeding stations in Thailand were used. REML bivariate animal models were used to estimate genetic correlations for each trait measure...

This study evaluates the nutrients digestibility and energy metabolism of crossbred cattle and buffaloes fed different ratio of concentrate and roughage based ration. 12 adult animals were used of three groups of cattle and buffalo, the following: cattle (Bos taurus × Bos indicus) (n=6) and buffalo (Bubalus bubalis) (n=6). Three groups of animals, each consisting two crossbred cattle, and two b...

INTRODUCTION Mastitis is a multifaceted disease with varied etiology, damaging the dairy economy, worldwide. Hence, the importance of timely diagnosis of this disease is represented well in saying, "A day lost is quarter lost"! Focus was to investigate the etioprevalence of sub clinical mastitis (SCM) in Holstein x Haryana crossbred cattle. The relationship between somatic cell count (SCC) and ...

this was a study to investigate quantitative and qualitative characteristics of fiber extracted from crossbred goats derived from female hair goats indigenous of qom and male cashmere goats of south of khorasan. from a total of 75 indigenous and cross goats aged 1-3, qualities such as the percentage of cashmere in fleece, percentage of hair in fleece, hair staple length, cashmere staple length,...

Mechanisms of testicular thermoregulation, the relationship of scrotal, testicular vascular cone (TVC), and testicular morphology with thermoregulatory capability, and their effects on semen quality and sperm production were studied in 20 Bos indicus, 28 crossbred, and 26 Bos taurus bulls. The ratio of testicular artery length and volume to testicular volume were larger (P<0.05) in B. indicus a...

The aim of this study was to estimate genetic parameters for longevity from Swedish crossbred sows to investigate the possibilities of selecting for this trait. Data were collected from 16 commercial piglet-producing herds, on crossbred (Landrace × Yorkshire) sows farrowing in the period 1 January 2001 to 31 December 2004. The data set with records on 10 373 sows was split into two sets accordi...

the effect of daily oral administration of ephedrine (0, 1, 2, 4 or 8 mg kg-1 w0.75) on carcasscharacteristics of forty-four 2 yr old crossbred (mehraban x ghezel) fat-tailed ewes was studied. theewes were fed a fattening ration, and received ephedrine by using a drenching gun for either 50 or 70days. there was a significant interaction (p
