Isolated Rearing at Lactation Increases Gut Microbial Diversity and Post-weaning Performance in Pigs

Effect of rearing system on pre-weaning growth, rumen development and its influence on post-weaning performance of lambs

Twenty-four 21-day-old Balouchi male lambs were equally divided into two groups. Twelve subjects were artificially reared (AR), twelve others were ewe reared (ER) and used as control. AR in comparison of ER lambs maintained higher concentrations of blood betaHydroxybutyric acid (BHBA); however glucose concentration was not affected by rearing system. Unlike the DNA content and cell size, the RN...

Nutritional management of gut health in pigs around weaning.

Early weaning of piglets is often accompanied by a severe growth check and diarrhoea. It is well established that this process is multi-factorial and that post-weaning anorexia and undernutrition are major aetiological factors. Gastrointestinal disturbances include alterations in small intestine architecture and enzyme activities. Recent data indicate transiently-increased mucosal permeability,...

Artificial rearing of pigs

I . Baby pigs were removed from the sow 36-48 h after birth and reared on a diet of reconstituted whole-milk powder until 28 d of age. The whole milk was either mildly or severely heated before spray-drying ; the severe heating completely denatured the whey proteins. 2. When the two milks were given at a high level of intake, either at hourly intervals or twice daily, severe scouring and some d...

Artificial rearing of pigs

I. Diets containing different proportions of skim milk and fat, either beef tallow or soyabean oil, supplemented with fat-soluble vitamins were given to 2-d-old pigs. Each fat source was used in three diets containing approximately 280, 350 and 420 g fat, and 260, 235 and 210 g protein/kg dry matter respectively. 2. The diets were given as a milk containing zoo g solids/l during a 26 d experime...
