background: sheep are a form of investment and a quickly liquidatable resource, particularly in traditional and low income production systems. tropical and long warm-season regions always affect sheep production negatively. methods: in this experiment 15 female and 7 male sheep were chosen and their body temperature, heart rate, respiration rate measurements and blood sample for biochemical par...

Background and Aims: Prevention of Lumpy skin disease (LSD) in cattle is heavily dependent on vaccination. Since the genetic structure of LSD virus has the close relatedness with other Capri-pox virus (CaPV). Therefore, the use of vaccine strains of CaPV derived from sheep and goat would be useful to protect cattle against LSD. Materials and Methods: The susceptible calves of dairy farms were ...

Pedigree MatchMaker is an RFID panel reader system that collects sheep movements to and from watering points over a 2 week period to identify pedigree. While this system was primarily developed to identify the pedigree of lambs, it may also provide information relating to lamb and ewe behaviour traits which influence sheep performance. Traits were calculated from the Pedigree MatchMaker data to...

By studying carcass quality, expressed as affection, pathological findings, slaughter-weight and evaluation, a picture of an animal's health and potential as high quality food is achieved. This study compares the carcass quality in Swedish certified organic meat production with that of conventional meat production slaughtered during 1997. The study involves 3.9 million pigs, about 570,000 cattl...

In this paper we consider different models that assess eco-efficiency with production frontier estimation when both desirable outputs and undesirable outputs (or residuals) are considered. These models are confronted to livestock farm data (sheep meat farms) and greenhouse gas (GHG) emissions, to discuss their suitability in ecoefficiency measurement. The application is to French sheep meat far...

Methionine synthase (MTR) plays a crucial role in maintaining homeostasis of intracellular methionine, folate, and homocysteine, and its activity correlates with DNA methylation in many mammalian tissues. Our previous genomewide association study identified that 1 SNP located in the gene was associated with several wool production and quality traits in Chinese Merino. To confirm the potential i...

We examined the role of metabolic CO2 production in the hyperpnea of muscular exercise by comparing the response of alveolar ventilation to moderate levels of exercise with the response to venous infusion of CO2 at rest. Studies were performed in four awake sheep that were trained to run on a treadmill. The sheep had been cannulated for veno-venous extracorporeal perfusion so that CO2 could be ...

This study investigated the hormonal regulation of lactate production and the lactate production/glucose utilization ratio in sheep and cow adipose tissue (AT) explants. The effects of insulin (2 mU/mL) and/or dexamethasone (DEX, 100 nM) were measured in perirenal AT of adult non-lactating non-pregnant cows (n = 5) or ewes (n = 5) given a restricted diet followed by overfeeding. The AT explants...

Karakul sheep breed has a lot to offer to livestock production in many parts of Botswana. This breed of sheep is acclimatised to desert conditions, which prevail in most parts of Botswana. This breed produces a range of products viz meat, milk, fur/pelt and wool, allowing for diversification of farm produce hence reduced risks attached to the production of a single product. The Karakul breed ha...
