Between the mid 1970s and the end of the 1980s a research programme evaluated hybridisation of red deer, initially with wapiti‐type captured animals and then with purebred wapiti imported from Canada. The cost of the research programme in 2001 doll

SUMMARYForty-eight cross-bred wether lambs were used to measure the effects of severe feed restriction and realimentation on the body and carcass composition of immature sheep. Ten of the total number of sheep were used as an initial slaughter group,

SUMMARYExperimental conditions and design were described in part I. Separable lean and fat were highly correlated with the carcass and whole body components of protein and ether extract. The carcasses of refed sheep at 45 kg empty body weight (EBW) h

SUMMARYExperimental conditions and design were described in Part I. When compared with continuous growth, there was a 46% increase in rate of gain following refeeding, but no increase in intake per kg0·734 (MBS) per day. Part of the reason for this

Intraperitoneal (IpMe) and oral (OrMe) supplements of DL-methionine were given to 9-month-old Romney sheep grazing swedes, turnips, or kale for two consecutive 3-week periods. Both OrMe and IpMe increased total live-weight gain of the sheep grazing k

In a trial on winter feeding of hoggets, soil in faeces of animals grazing swedes reached a weekly mean of 61% of faeces D.M. Soil ingested reached a weekly mean of 1 kg. Soil in faeces increased progressively as swedes were eaten down to ground leve

When Romney ewe hoggets were fed at three levels of winter nutrition and subsequently fed at two levels during spring-summer, between 60 and 133% of the winter weight differences were recovered during spring-summer. Regression analysis showed that 83

The comparative nutritive value of five winter forage crops was studied over a 42-day period using Romney hoggets. The apparent digestibility coefficients for energy were swedes 90.8%, turnips 90.1%, chou moellier 83.0%, mangolds 86.4%, and fodder be
