This paper presents a first genetic linkage map of the goat genome. Primers derived from the flanking sequences of 612 bovine, ovine and goat microsatellite markers were gathered and tested for amplification with goat DNA under standardized PCR conditions. This screen made it possible to choose a set of 55 polymorphic markers that can be used in the three species and to define a panel of 223 mi...

BACKGROUND Liaoning cashmere goat is a famous goat breed for cashmere wool. In order to increase the transcriptome data and accelerate genetic improvement for this breed, we performed de novo transcriptome sequencing to generate the first expressed sequence tag dataset for the Liaoning cashmere goat, using next-generation sequencing technology. RESULTS Transcriptome sequencing of Liaoning cas...

Ghrelin acts as an endocrine link connecting physiological processes regulating food intake, body composition, growth, and energy balance. Ghrelin is the only peptide known to undergo octanoylation. The enzyme mediating this process, ghrelin O-acyltransferase (GOAT), is expressed in the gastrointestinal tract (GI; primary source of circulating ghrelin) as well as other tissues. The present stud...

Taste perception plays an important role in regulating food preference, eating behavior and energy homeostasis. Taste perception is modulated by a variety of factors, including gastric hormones such as ghrelin. Ghrelin can regulate growth hormone release, food intake, adiposity, and energy metabolism. Octanoylation of ghrelin by ghrelin O-acyltransferase (GOAT) is a specific post-translational ...

In Oklahoma, goat producers are blessed with climatic conditions conducive to viable goat production. However, they also are burdened with the eastward expansion of predator populations that constantly are increasing. Predator control within a goat herd is probably one of the single most important factors in maintaining profitable returns from a goat operation. In 2004, U.S. losses of goats and...

Behavioural plasticity allows animals to adjust rapidly to local environmental conditions, but at the risk of erroneously changing behaviour in response to irrelevant events. Adaptive biases or predispositions constrain learning and reduce such potential costs. Preferential learning about complex biologicallymeaningful stimuli, such as predators, has been investigated in only a few systems and ...

background: cross-contamination between cells is a usual mistake at cell culture laboratories and cell banks worldwide. mrc5 diploid cell and rk-13, vero and hela continuous cell lines are used in different stages of human viral vaccines propagation at razi vaccine and serum research institute of iran. however diploid and continuous cells are propagated at separated cell culture laboratory and ...

The relationships between goat κ-casein (CSN3) variants and milk composition were studied in 1143 goats from 4 breeds (Camosciata, Frisa, Orobica, Verzasca). Individual milk samples were analysed by isoelectrofocusing. The effect of CSN3 type on protein and casein content was evident, B variant being associated to higher levels of both traits. Since the B variant is mainly present in local capr...

Bovine viral diarrhoea virus (BVDV) is an economically important pathogen of cattle worldwide. Infection of a pregnant animal may lead to persistent infection of the foetus and birth of a persistently infected (PI) calf that sheds the virus throughout its life. However, BVD viruses are not strictly species specific. BVDV has been isolated from many domesticated and wild ruminants. This is of pr...
