Growth Intensity of Lambs during Artificial Milk Rearing Depending on Chosen Non Genetic Factors

The aim of the research was to evaluate the influence of sex, breeding group, litter size and age of lambs when placed in lambing pens for their growth rate during rearing. The average daily gain of lambs was evaluated based on their weighing data each week after their placement into lambing pens. Lambs of Improved Valachian, Tsigai and Lacaune breed (n=26) had been gradually integrated to the ...

Lactation curves of commercial ewes rearing lambs.

Three-hour milk production measurements determined by machine milking at 3-d intervals throughout a 63-d lactation period were used to describe lactation curves for crossbred ewes lambing at 1 and 2 yr of age and rearing single and twin lambs. Age of ewe, type of rearing, and day of lactation affected (P < 0.05) milk production. Over the 63-d lactation, average daily milk production was 2.56 an...

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...
