Effect of feed restriction on compensatory growth and body dimensions in Ujumuqin lambs
Livestock production in northeast mixed cropping and animal husbandry of China depends on natural pasture and crop residues.It is largely influenced by availability that fluctuates.Without influencing the early growth of pasture but maintaining the compensatory growth ability of animals,it is feasible to feed the animals restrictedly in early spring in order to take full advantage of pasture and exploit the growth potential of animals One of the objectives of this experiment was to determine the effects of different levels of feed restriction on growth rate and body dimensions of re‐fed lambs in spring.Another objective was to investigate if there is certain difference of grazing behavior between the restricted groups and control group and which affect the intake.
