the present study was performed to evaluate the on-station growth performance of local and dorper × local crossbred sheep in eastern amhara region, ethiopia. data on 302 lambs collected over a 4-year period (2009 to 2012) on local and dorper × local crossbred sheep at sirinka breeding, evaluation and distribution site were used in this study. fixed effects considered were breed, lamb sex, birth...

Recombination is a complex biological process that results from a cascade of multiple events during meiosis. Understanding the genetic determinism of recombination can help to understand if and how these events are interacting. To tackle this question, we studied the patterns of recombination in sheep, using multiple approaches and data sets. We constructed male recombination maps in a dairy br...

This study aimed to evaluate the influence of concentrate supplementation on the ingestive behaviour of grazing ewes. Twelve pregnant pluriparous sheep were used, six of the Santa Inês breed and six of the Morada Nova breed. The supplement was formulated to supply the animals with two feed levels (0.5% and 1.5% of body weight) of nutrition. The experimental design was a randomized 2 x 2 x 2 fac...

The aim of this study was to investigate the influence of the MyoD1 gene polymorphisms on some body parameters in sheep. MyoD1 polymorphisms were detected using NimbleGen sequencing technology (Roche, USA). The effect of polymorphisms identified was investigated in Stavropol sheep breed rams (n=30). In coding and regulatory parts of gene 26, single nucleotide polymorphisms (SNP) were detected. ...

Introduction: The aim of the present study was to evaluate the morphometric differences of the skull in male and female Zell sheep. Methods: For this purpose, 30 heads (15 adult males and 15 adult female) of Zell sheep breed were collected from the local slaughter-house. The skulls were prepared using the boiling maceration according to the usual techniques, and the mandible was dissociated fr...

Albania is a Mediterranean country, located in West of Balkan Peninsula. Albanian farmers have a long tradition in sheep breeding. Sheep comprise one of the most important domestic livestock species in Albania and play an important role in the livelihood of local community since they are a good source of meat, milk and coarse wool (Dobi et al., 2006; Porcu and Markovic, 2005). There are three i...

A suspended-net technique was used to capture blackflies attracted to and engorging on Dorper and Merino sheep on irrigated pastures. Two bait animals of each breed were restrained individually in wire-mesh enclosures located within four larger pens, each containing nine more animals of the same breed. Nets were suspended partly over the restrained animals and blackflies were collected at the e...

The article presents the dynamics of changes in live weight for a year, measurements, body build indices and productivity one-year-old pure-bred Kazakh fine-wool female lambs crossbreeds different bloods with German meat merino, when creating sheep breed south-east Kazakhstan - “Etti merino”. resulting crossbred offspring are characterized as large animals, high good forms.

Immunoblotting of Cowdria ruminantium proteins with sheep or bovine antiserum identified 2 antigenically conserved proteins, one being an immunodominant 31 kDa and the other a minor 27 kDa protein. These proteins are present in the electrophoretic profiles of the Welgevonden, Ball 3 and Kwanyanga stocks and are recognized by sheep antiserum to the Welgevonden, Ball 3, Kwanyanga, Mali, Comoro, B...
