hepatic and renal contents of essential trace elements provide good clues to monitor the nutritional status of grazing animals. liver and kidney samples were collected from 60 sheep and 60 goats slaughtered in zarrinshahr abattoirs and analyzed for essential trace elements. hepatic fe concentrations were significantly higher in sheep than goats. there were also higher renal and hepatic fe conce...

Agricultural sector accounts for about 1/3 of the Iranian GDP and 1/4 of the country workforce. More than 90% of the Iranian food requirements are produced in the country. Animal agriculture covers over 40% of the agricultural activities. More than 57% of the available animal units in the country are sheep and goats. Desertification, deforestation, water shortage, erosion, low efficiency and ou...

Studies on daily rhythmicity in livestock under natural conditions are limited, and there is mounting evidence that rhythm patterns differ between chronobiological studies conducted in the laboratory and studies conducted under pronounced natural seasonality. Here, we investigated the influence of cold-dry (harmattan) and hot-dry seasons on daily rhythmicity of rectal (RT) and body surface temp...

Scrapie is a fatal, neurodegenerative disease of sheep and goats. It is also the earliest known member in the family of diseases classified as transmissible spongiform encephalopathies (TSE) or prion diseases, which includes Creutzfeldt-Jakob disease in humans, bovine spongiform encephalopathy (BSE), and chronic wasting disease in cervids. The recent revelation of naturally occurring BSE in a g...

Profitable sheep and goat production in the USA is severely limited by gastrointestinal nematode (GIN) parasitism, particularly by Haemonchus contortus. Copper oxide wire particles (COWP) have anti-parasitic properties in the diet of small ruminants, but efficacy of COWP may differ between sheep and goats. In a study with weaned kids (Kiko x Spanish cross, 6 months old) and lambs (Katahdin or D...

Sheep and goats are the earliest ruminants to be domesticated. They can withstand a period of draught better than any other livestock and they can use those pastures, which cannot be used by other livestock. Sheep and goat rearing plays an important role in the livelihood of poor, small and marginal farmers and provides a major source of income especially through self-employment and guaranteed ...

A study was conducted to evaluate serum and tissue micro-mineral concentrations of sheep and goats at the end of the dry and wet seasons in Trinidad. Tissue Samples for analysis were taken from the same liver lobe, the kidney cortex mainly (and outer medulla) and the cerebral hemispheres. Tissue sample trace concentrations were for Cu, Zn, Fe and Mn were determined by Atomic absorption spectros...
