Breeding tolerant pigs for health and productivity
نویسندگان
چکیده
The majority of Australian piggeries rely on antibiotics classified as ‘low' importance in human medicine (Jordan et al., 2009). However, there is evidence of antimicrobial resistance to pathogens sampled in pig carcases that are of significant importance to human health, such as Escherichia coli (Smith et al., 2010). With increasing consumer awareness of medicine use and pressure for more welfare-friendly approaches in agriculture, pig breeders are faced with finding alternative strategies for production.

Evaluation of Drought Tolerance in Safflower (Carthamus tinctorius L.) Under Water Deficit Stress Conditions
Drought is a threaded factor in the world production and application of breeding methods could improve the tolerant and adapted cultivators under drought stress condition. In order to evaluate and determine the stress tolerance indices and identifion of tolerant genotypes to drought stress, 15 safflower genotypes were evaluated in a randomized complete block design with three replications in tw...
متن کاملTowards healthy, productive genotypes
Selection for high productivity has been the long term focus of pig breeding programs worldwide, however, Rauw et al. (1998) highlighted that selection for productivity alone has unfavourable consequences for a number of metabolic, reproduction and health traits across species. More recently, Prunier et al. (2010) reviewed relationships between high physiological demands and the health and welf...
متن کاملSelection for productivity and robustness traits in pigs
Pig breeding programs worldwide continue to focus on both productivity and robustness. This selection emphasis has to be accompanied by provision of better-quality environments to pigs to improve performance and to enhance health and welfare of pigs. Definition of broader breeding objectives that include robustness traits in addition to production traits is the first step in the development of ...

Breeding for environmental stress is one of the most important goals in plant breeding. Among stresses, drought stress has high influencing on limitation of maize production. Therefore, in order to find the best drought tolerant hybrids, 38 maize hybrids were planted in two separate experiments: one with optimum irrigation (control) and another with water stress at grain-filling stage in Moghan...
متن کاملFactors for improving reproductive performance of sows and herd productivity in commercial breeding herds
We review critical factors associated with reproductive performance of female breeding pigs, their lifetime performance and herd productivity in commercial herds. The factors include both sow-level and herd-level factors. High risk sow-level groups for decreasing reproductive performance of female pigs are low or high parity, increased outdoor temperature, decreased lactation feed intake, singl...
