Global competition for high standard feed-food resources between man and livestock, such as industrial broilers, is a concerning problem. In addition, the low productivity of scavenger chickens in developing countries leaves much to be desired. Changing the ingredients, and therefore, the nutrient composition of feed intake by commercial fed as well as scavenger chickens seems like an obvious s...

Indigenous (native) breeds of livestock have higher disease resistance and adaptation to the environment due to high genetic diversity. Even though their extinction rate is accelerated due to the increase of commercial breeds, natural disaster, and civil war, there is a lack of well-established databases for the native breeds. Thus, we constructed the native pig and chicken breed database (NPCD...

Numerous factors affect livestock production and productivity. In this chapter we will address those that are of paramount importance: climate, nutrition, and health aspects. In initial section we will review the effects of climate on livestock productivity and provide examples of livestock adaptation to climate constraints such as the Bos indicus cattle breeds adapted to hot weather and the fa...

Merauke is one of seventeen districts selected for strengthening beef cattle breeding activities to provide livestock germs, especially local livestock, through domestic procurement. The sustainability production supplies must be supported by the availability quality breeds. Superior are determining factors and have a strategic value in effort develop cattle. Criteria evaluating breeds, includi...

C ROSSBREEDING involves the mating of two or more breeds. In most species of domestic livestock, crossbreeding has some desirable consequences, especially in the production of market stock. These consequences are the production of heterosis, the opportunity to incorporate desirable genetic material quickly, and the chance to combine several desirable traits into a market animal. The consequence...

The recent release of the Bovine HapMap dataset represents the most detailed survey of bovine genetic diversity to date, providing an important resource for the design and development of livestock production. We studied this dataset, comprising more than 30,000 Single Nucleotide Polymorphisms (SNPs) for 19 breeds (13 taurine, three zebu, and three hybrid breeds), seeking to identify small panel...

ICAR Technical Series No 3 Animal breeding aims for genetic improvement of livestock by utilising the genetic variation available, both within breeds and between breeds. The animal genetic variation can be used to accommodate interests and farmers’ wishes to make livestock more efficient in using available resources to produce human food and other agricultural products. In general, improved per...

This study characterized autochthonous pig breeds of Vietnam and compared them with breeds from other regions. A total of 343 animals were considered from 5 indigenous pig breeds of Vietnam (Muong Khuong, Co, Meo, Tap Na, and Mong Cai), 2 exotic breeds kept in Vietnam (Landrace and Yorkshire), 3 European commercial breeds (German Land-race, Piétrain, and Large White), the Chinese breed Meishan,...

In the recent years, the number of endangered animals, both referred to livestock and wild species, has grown enormously. The “livestock” term refers to animals domesticated for producing commodities for man such as food, fiber and draught. Livestock biodiversity is integral to our culture, history, environment, and economy. Thousands of livestock breeds have evolved over time to suit particula...

The management of livestock breeds and threatened natural population share common challenges, including small effective population sizes, high risk of inbreeding, and the potential benefits and costs associated with mixing disparate gene pools. Here, we consider what has been learnt about these issues, the ways in which the knowledge gained from one area might be applied to the other, and the p...
