The study was aimed to provide baseline data regarding haemato-biochemical and endocrine profiling of Gaddi sheep found in north western Himalayan region of Himachal Pradesh, India. Each random sample was collected from 45 Gaddi sheep reared in government sheep breeding farm Tal, Hamirpur, India, during various reproductive phases viz. anestrus, breeding season and post partum period. Haematolo...

The aim of this study was to describe inbreeding and population structure in Sangsari sheep breeding station. For this reason, data from 7028 Sangsari sheep which were collected during 1987-2014 in Sangsari sheep breeding station located near to Damghan city, Semnan province were used. Lambs born during 2010-2014 were considered as reference population. The genetic structure analysis of the pop...

Through the use of assisted reproductive technology (ART), we will be able to extend the use of genetically superior animals, and perhaps increase the number of offspring. These technologies include such procedures as estrus synchronization, superovulation, artificial insemination, embryo transfer, in vitro fertilization (IVF), and cloning. Because they exhibit seasonal breeding and multiple ov...

Unlike most domestic livestock species, sheep are widely known as an animal with marked seasonality of breeding activity. The annual cycle of daily photoperiod has been identified as the determinant factor of this phenomenon, while environmental temperature, nutritional status, social interactions, lambing date and lactation period are considered to modulate it. The aim of this paper is to revi...

Local sheep breeders and scientists in Italy cooperate and conduct research on the genetic improvement of autochthonous genetic types (AGTs) by various approaches, including a cytogenetic breeding selection since 2011. The Laticauda sheep (Ovis aries, 2n = 54) breed is one of the AGTs reared in the Campania region (southern Italy). Performing cytogenetic analyses, we have detected and described...

the kermani sheep is an important meat producing an animal in iran and its economic efficiency is mainly dependent on its growth and reproduction ability. inter-simple sequence repeat (issr) is the genome region between microsatellite loci. the aim of this study was to evaluate the association of two different issr markers with predicted breeding values (pbv) of body weight trait in kermani she...

Market failures are the main cause of poor acknowledgement of the true impact of functional sheep traits on the management and economic performance of farms, which results in their omission from the breeding goal or the estimation of non-representative economic weights in the breeding goal. Consequently, stated-preference non-market valuation techniques, which recently emerged to mitigate these...
