We evaluated the profitability of anthelmintic treatment and nutritional supplements using partial budget analysis on 108 weaned Menz (n=39), 50% Awassi-Menz (n=38) and 75% Awassi-Menz (n=31) crossbred sheep genotypes kept on-station under subclinical helminthosis at Debre Berhan, Ethiopia. Data were collected on feed intake, live weight, eggs per gram of faeces (EPG), packed cell volume (PCV),...

Although a lower transfusion trigger is generally recommended, little evidence is available about the physiological mechanisms of mild anemia in diseases with an imbalance between O2supply and O2 demand such as sepsis. This study was undertaken to describe the systemic and coronary metabolic O2 reserve in an awake sheep model of hyperdynamic sepsis comparing two different hemoglobin levels. Twe...

One of the most important human social skills is the ability to recognize faces. Humans recognize familiar faces easily, and can learn to identify unfamiliar faces from repeatedly presented images. Sheep are social animals that can recognize other sheep as well as familiar humans. Little is known, however, about their holistic face-processing abilities. In this study, we trained eight sheep (Ov...

Examination of the lungs of adult sheep with chronic respiratory diseases was readily achieved using both 5 MHz linear and sector scanners. Superficial lung abscesses in eight sheep appeared as anechoic areas containing multiple hyperechoic dots bordered distally by a broad hyperechoic capsule. Unilateral fibrinous pleurisy (2 sheep) appeared as an anechoic area containing a hyperechoic lattice...

1. Carnitine acetyltransferase (EC 2.3.1.7) activity in sheep liver mitochondria was 76nmol/min per mg of protein, in contrast with 1.7 for rat liver mitochondria. The activity in bovine liver mitochondria was comparable with that of sheep liver mitochondria. Carnitine palmitoyltransferase activity was the same in both sheep and rat liver mitochondria. 2. The [free carnitine]/[acetylcarnitine] ...

Objective: Cystic echinococcosis (CE) is an important parasitic infection caused by Echinococcus granulosus (E. granulosus) larvae, adults of which live in Canidae. Although CE observed all over the world, it more prevalent developing and underdeveloped nations.
 Material Method: This study was conducted on a total 60 cyst samples, including 20 sheep cattle slaughtered abattoir patients op...

1. A group of normal and congenitally goitrous Merino sheep were investigated to identify the metabolic defect present in the abnormal animals. 2. Protein-bound iodine concentrations of serum from goitrous animals (average 5.7mug./100ml.) were higher than normal (average 4.2mug./100ml.; P 0.001), but the hormonal iodine measured as butanol-extractable (131)I was low in the serum of goitrous (av...

This study was done from September 2006 to May 2007. A total of 105 Menz breed sheep from Yemenze Gera Midir district in the Amhara National Regional State, Ethiopia. The spatial distribution of sheep keds (Melophagus ovinus) and chewing lice (Bovicola ovis) on Menz breed sheep were examined which were naturally infested. The densities if sheep keds and lice were determined through counting aft...

BACKGROUND Sheep (Ovis aries) were domesticated in the Fertile Crescent region about 9,000-8,000 years ago. Currently, few mitochondrial (mt) DNA studies are available on archaeological sheep. In particular, no data on archaeological European sheep are available. METHODOLOGY/PRINCIPAL FINDINGS Here we describe the first portion of mtDNA sequence of a Copper Age European sheep. DNA was extract...

Lameness in sheep continues to be a global health, welfare and economic concern. Damaged, misshapen or overgrown feet have the potential cause lameness either directly, indirectly. There is lack of understanding predisposing factors for different hoof conformation traits sheep. Our exploratory study aimed investigate prevalence of, risk for, three distinct relating sole heel, wall, wall overgro...
