Indigenous sheep of Kenya are very important to resource-poor farmers and pastoralists. They have over time adapted to the harsh environmental conditions of the arid and semi-arid lands where they are faced with challenges of persistent droughts, diseases, conflicts and poor nutrition, yet show resistance to gastrointestinal nematodes. In recent years, these indigenous sheep populations have be...

Heterosis Heterosis, or hybrid vigor, refers to the increased vitality or “doing ability” of the crossbreds as compared to the average of the parental breeds. The only way to get heterosis is through crossbreeding. Heterosis is expressed by the crossbred lamb (individual) and by the crossbred ewe (maternal). Crossbred lambs, on the average, are more vigorous and have a higher survivability than...

The identification of meat quality characteristics from selected breeds grazing in specific regions is particularly relevant to achieve a marketing advantage. Longisimus thoracis at lumborum (LTL) from the indigenous Western Balkan (WB) sheep VlašićkaPramenka (VP) sheep and lambs, and Pivska Pramenka (PP) sheep grazing in Bosnia & Herzegovina (B&H) and Montenegro (MN), respectively, was compare...

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.

ABST RACT The objective of this immunohistochemical study was to examine the expression of caspase-3,-5,-7, and -9 in sheep pox lesions in 15 naturally infected crossbred merino lambs. Sheep pox was diagnosed based on typical gross and histopathological lesions in the skin and visceral organs that were evaluated pathologically and immunohistochemically. Macroscopically, lesions were observed in...

Background: With the increasing concern for health and nutrition, dietary fat has attracted considerable attention. The composition of fatty acids in the diet is important because they are associated with major diseases including cancers, diabetes, and cardiovascular disease. The fatty acid synthase (FASN) and stearoyl-CoA desaturase (delta-9-desaturase) (SCD) genes affect fatty acid compositio...
