Twelve crossbred does (New Zealand White x California) were offered a diet of high protein and metabolizable energy content (249 g/kg dry matter (DM) and 13.6 MJ/kg DM respectively) throughout a 32 d lactation at one of four feeding levels (240, 280, 320 or 360 g/d). Each feeding level was replicated three times. Milk output was measured by weighing the(More)
1. Measurements were made of energy balance by direct calorimetry, and of nitrogen balance in groups of lean and congenitally obese ('fatty') Zucker rats at body-weights of 200 and 350 g given a highly digestible semisynthetic diet at 14-0 or 18-4 g/rat per 24 h. 2. Losses of food energy and N in faeces were very small. The fatty rats lost much more N in(More)
I. Heat losses associated with the utilization of metabolizable energy for synthesis of protein and of fat during growth mere studied in Zuekcr rats selected for normal leanncss or congenital obesity. z. Measurements of energy and nitrogen balance were made on groups of four lean and four fat rats offered food ad lib. and kept at zzo. Balance trials were(More)
