The sources of variation of health claimable omega-3 polyunsaturated fatty acids (eicosapentaenoic acid, EPA+docosahexaenoic acid, DHA) in 2000 Australian lambs were investigated using 98 sires (Merino, maternal or terminal breeds) that were mated to about 5000 Merino or crossbred (Border Leicester×Merino) ewes. Pasture was supplemented with feedlot pellets, grains or hay as necessary, when the...

The aim of this study was to evaluate and compare the quality characteristics, chemical composition lipid profile lamb meat from Italian (Biellese Sambucana) German (Texel-Merino-Blackhead-Charollais [TMBC]) breeds reared in extensive semi-extensive production systems. Meat samples 89 animals were analysed. lambs semi-intensively Biellese, extensively Sambucana TMBC produced lean meat, with sli...

The main objective of this study was to evaluate the effects of supplementing lactating ewe diets with extruded linseed on the fatty acid (FA) composition of intramuscular and subcutaneous fat depots of suckling lambs. Twenty-four pregnant Churra ewes were divided into two groups based on the milk production, age, body weight and parity, and assigned to one of two treatments. Each ewe of the Co...

In Southern Patagonia, grasslands are the principal food resource for sheep reared meat and wool as main provisioning ecosystem services (ES). The objective of this study was to model lamb production ES at a regional scale using climatic, topographic, vegetation variables from farms across Santa Cruz province. At level, animal yield ranged 0.25 0.69 g lamb/m2/yr 0.10 0.19 greasy wool/m2/yr. We ...

Possible correlated or pleiotropic effects on food intake, growth rate and carcass traits (meat quality and carcass composition traits) were investigated for the prolificacy related Booroola gene (FecB). This gene was introgressed in a Texel sheep population by systematic backcrossing with sires carrying the Booroola gene. In a 3-year experiment 273 spring-born male lambs were offered concentra...

In the present paper, it is studied the price relations and how price is transmitted between the producer level and the consumer level for lamb meat. Data used in the research include consumer price index and producer price index for lamb meat covering monthly periods of 91 months since March 2001 through September 2008. Johansen's and Juselius's cointegration method and Granger causality test ...

A negative correlation exists between calpastatin activity and meat tenderness. Therefore, it is important to determine the mechanism of calpastatin inactivation in postmortem skeletal muscle. Western immunoblot analysis was performed to determine the protease(s) responsible for degradation of muscle calpastatin during postmortem storage. To accomplish this, purified calpastatin was digested wi...

During July 1995, an outbreak of Salmonella typhimurium definitive type (DT) 170, an unusual strain, occurred in South Wales. A case-control study found that illness was associated with eating kebabs (odds ratio undefined, P = 0.002), doner kebabs (odds ratio 7.9, 95 % confidence interval 1.5-20.5, P = 0.02) and kebabs with yoghurt based relish (odds ratio undefined, P = 0.009) but not with eat...

Inspired by the health conscious consumer, several studies in meat producing domesticated animals have been completed that have aimed at increasing the polyunsaturated fatty acid content, and in particular the n-3 or -3 long chain fatty acids, as well as the conjugated linoleic acid (CLA) content in intramuscular fat of beef, lamb and pork meat. Increasing the n-3 content in animal meats can be...
