	abstract = {Two hundred 2-tooth (2T) and mixed age (MA) cashmere does were   randomly allocated to one of 4 feeding levels to evaluate the effect of   pasture allowance on liveweight change and reproductive performance.   Pasture allowances of 0.8 (L), 1.2 (M), 2.5 (M+) and 5.0+ (H) kgGM/hd/d   were imposed for 8 weeks prior to mating. Does were weighed fortnightly   and laparoscroped at 10 (CL10) and 20 (CL20) days post buck   introduction.     Weight change over 8 weeks was -2.2kg (L), 0.1kg (M), 0.3kg (M+) and   1.8kg (H) and was significant (P<0.01) for L, M+ and H treatments.   Pasture allowance had no effect on proportion of does ovulating (CL10   and CL20) but does on the L and M allowance averaged fewer multiple   ovulations than does on the M+ and H allowances (14\% vs 23\%) at day 10   after mating.     A high proportion (P,0.01) of MA does were ovulating 10 days after   mating (78.7\% vs 58.2\%) and MA does had more multiple ovulations at 10   (52.1\% vs 11.3\%) and 20 (40.2\% vs 13.5\%) days after mating than 2T does.   There were more (P<0.01) MA does pregnant (76.3\% vs 57.1\%) and more   multiple pregnancies in MA does (44.6\% vs 17.3\%) than 2T does.     This trial showed that age is a major factor in determining proportion   of multiple ovulations and multiple pregnancies in cashmere goats. It   highlighted the confounding effect of age on liveweight and the   difficulty in separating the effects of pasture allowance from the   effects of liveweight, on reproductive performance.    },
