Effective nutritional management during gestation has long been recognized as an important component of sound livestock production practices (Bull and Carroll, 1937; Barcroft, 1946; Morrison, 1949; Maynard and Loosli, 1956; Crampton and Lloyd, 1959; NRC, 1970). Recent observation in the area of developmental programming (Barker et al., 1992; Barker et al., 1993; Godfrey and Barker, 2000; Barker...

Concerns over the increasing emergence of antibiotic-resistant pathogenic microorganisms due to the overuse of antibiotics and the lack of effective antibiotics for livestock have prompted efforts to develop alternatives to conventional antibiotics. Antimicrobial peptides (AMPs) with a broad-spectrum activity and rapid killing, along with little opportunity for the development of resistance, re...

Introduction In developing countries, livestock can be an important pathway out of poverty (FAO 2009; McDermott et al. 2010a; Rich et al. 2011). Over one billion people depend on livestock, which provide power and manure for crop production, contribute to food and nutritional security, and are a form of savings for many poor people. Livestock also make major contributions to the agricultural GD...

The objective of this work was to quantify the country’s NH3 emissions from livestock production. This calculation was based on the mass flow of total ammoniacal nitrogen (TAN). The analysis was performed for all 15 geographical regions in Chile. The definition of livestock subcategories was based on data from the Chilean Agriculture and Forestry Census as well as technical reports published by...

BACKGROUND Greenhouse gas (GHG) production, as a cause of climate change, is considered as one of the biggest problems society is currently facing. The livestock sector is one of the large contributors of anthropogenic GHG emissions. Also, large amounts of ammonia (NH(3)), leading to soil nitrification and acidification, are produced by livestock. Therefore other sources of animal protein, like...

This paper examines the vulnerabilities of major livestock species raised in Australia to climate change using the regional livestock profile of Australia of around 1,400 regions. The number of each species owned, the number of each species sold, and the aggregate livestock revenue across all species are examined. The four major species analyzed are sheep, beef cattle, dairy cattle, and pigs. T...

the conservation of gene-function and physiology between people and livestock species advocates for their utility in modeling human disease. Furthermore, agricultural animal production will play a pivotal role in providing high-quality protein to advance human health in the face of a burgeoning global population. Both the development of animal models and the improvement of livestock for food ca...
