We accept that we are responsible for the quality of life of animals in our care. We accept that the activities of man affect all the living things with which we share this planet. But we are slow to realize that as a result we have a duty of care for all living things. That duty extends to the breeding of animals for which we are responsible. When animals are bred by man for a purpose, the aim should be to meet certain goals: to improve the precision with which breeding outcomes can be predicted; to avoid the introduction and advance of characteristics deleterious to well-being; and to manage

Ten breeds of meat and combined productivity are bred in Ukraine, of which six are crossborder breeds and four are Ukrainian breeds developed through combination crossbreeding of local breeds with cross-border breeds. These breeds are located in different natural and climatic and agricultural zones, so it is important to investigate the indicators of meat productivity of breeds and the factors that influence them. The purpose of the study was to determine the influence of the breed, agricultural climate zone (zone) and calendar year (year) on the studied characteristics of meat cattle and to e

Two of the major steps in animal breeding programmes are (i) estimation of breeding values for a defined selection objective (such as milk production or carcass lean content), and (ii) design of optimum breeding programmes, including proportion of animals selected as parents, population size etc. Advances in electronics, and particularly in computer technology, have had a major Impact on these procedures in a number of ways. In this paper we aim to highlight four of these.The preferred method of estimating breeding values is universally recognised to be BLUP (Best Linear Unbiased Prediction).

The interaction effects of genotype and nutrition on the performance of sows during lactation is still poorly understood; this series of experiments explored the factors contributing to breed differences in lactational performance and the development of appropriate feeding strategies. Two extreme types of sow were used in these experiments; lean pure-bred White sows (W: Large White and Landrace) and a prolific but fatter Meishan synthetic damline (M: 50% Meishan genes).

Hair sheep are gaining popularity in lamb-only production systems as they are more adapted to hot climates and eliminate shearing costs.

Group treatment was staggered over the year in an attempt to dissociate breeding season advance from advanced coat growth.

Animal breeding relies on two processes to achieve its objectives: the selection and the mating systems. Mating systems devise a particular plan to perform one or more breeding goals, which often encompass improving the herd's health and maximising financial gains in animal production systems. Compensatory mating is a strategy to produce animals with more homogeneous selection trait characteristics, discarding the production of exceptional animals in favour of a more balanced herd.

Selection programs aiming at improving health and survival in cattle are complicated by low heritability estimates, the fact that true herd life and carcass quality is not known until the end of an animal's life, and that many health conditions manifest late in life. Young animals are now heavily favored in breeding programs because low generation intervals accelerate the rate of genetic progress, which means selection decisions must be made before phenotypic observation of health and survival is feasible. Moreover, profitability is compromised when livestock producers raise animals that fail

With roots as far as the Bronze age, equines have played an invaluable role in history, both with regards to agriculture and forestry, warfare, transportation and leisure, and therefore hold important cultural significance in the Nordics. The link between horses and the welfare benefits of their caregivers makes the species an important part of society as well. Since the agricultural and industrial revolution, the equine sector has been influenced by a range of challenges due to the dramatic change in the role of horses in society, especially for the Nordic native breeds. However, as society a

Improving plant cell wall (fiber) degradation remains one of the highest priority research goals for all ruminant enterprises dependent on forages, hay, silage, or other fibrous byproducts as energy sources, because it governs the provision of energy-yielding nutrients to the host animal. Although the predominant species of microbes responsible for ruminal fiber degradation are culturable, the enzymology and genetics underpinning the process are poorly defined. In that context, there were two broad objectives for this proposal. The first objective was to identify the key cellulosomal component

The main objectives of this research was to detect the specific polymorphisms responsible for observed quantitative trait loci and develop optimal strategies for genomic evaluations and selection for moderate (Israel) and large (US) dairy cattle populations. A joint evaluation using all phenotypic, pedigree, and genomic data is the optimal strategy. The specific objectives were: 1) to apply strategies for determination of the causative polymorphisms based on the “a posteriori granddaughter design” (APGD), 2) to develop methods to derive unbiased estimates of gene effects derived from SNP chips
