domestication of animals has had some important effects on physiology, morphology, behavior and well-being of domesticated animals. conscious or goal directed selections on animals for increasing their productions has accelerated the rate of the changes, leading to some well-being defections. this paper notes some aspects of animal domestication in context of genetic science. then explains how ...

Fourteen Boer (75%) x Spanish wether goats (51 ± 1.8 kg BW and 23 mo of age) were used to determine effects of a moderate degree of nutrient restriction on heat production (HP). The experiment consisted of a 26-d period (P1) followed by one of 46 d (P2). Wethers were fasted on the final 4 d of each period, with gas exchange measured on the last 2 d. Fasting was preceded by collection of feces a...

A high rate of gain in dairy heifers for #8805 3 mo is detrimental to prepubertal mammary growth and subsequent milk yield. However, the effects of a high rate of gain for shorter periods have not been reported. Our objective was to compare effects of high (1200 g/d) and low (600 g/d) rates of gain over different lengths of time (0, 3, 6, 12 wk) on body and mammary growth. Heifers (age = 11 wk,...

Infectious diseases of both humans and farm animals are re-emerging as significant problems, because our arsenal of effective anti-infective tools is not expanding proportionally. Thus, there is an urgent need for new approaches to the treatment of infectious disease, especially in cases of drug-resistant microbes, microbes for which therapy is not available, or in cases of host immune impairme...

Adopting the concept of One Welfare could help to improve animal welfare and human wellbeing worldwide, argue Rebeca García Pinillos, Michael Appleby, Xavier Manteca, Freda Scott-Park, Charles Smith and Antonio Velarde.

This paper reviews the possibilities of adapting laying hens to cages by means of genetic selection. By selecting separately for rate of lay and longevity using a kin selection method, a strain of laying hen has been developed that shows much less feather pecking and cannibalism than a control strain, and with no decrease in productivity. This experimental strain enjoys a higher level of welfar...
