	abstract = { A multi-year grazing study was undertaken on three commercial properties in the southern South Island to compare the performance
of lambs grazing high-sugar ryegrass/white clover (HSG) with lambs grazing a standard ryegrass/white clover pasture (SRG).
Cultivars were established in late spring 2012; approximately 400 lambs in each treatment group per property grazed the swards in
autumn 2013 and summer/autumn 2014 at a density of 30 to 35 lambs per hectare. Lambs were weighed regularly throughout the
season; those that reached the desired weight were sent for slaughter. Across both years and properties, lambs grazing the HSG
pasture grew 31 grams per day faster (17\%) on average than those grazing SRG (P<0.001). These lambs were an average of 0.4 kg
heavier in terms of carcase weight at slaughter (P<0.001) yielding 0.2 kg more meat per carcase based on VIAScan yield. These
results suggest that lambs grazing HSG outperform those grazing SRG.},

	abstract = { A study was undertaken on three properties throughout New Zealand to determine the impact of shearing on lamb performance
and whether this offered any economic benefit to farmers as a farm-management tool. A total of 1,183 lambs were randomly
allocated to one of four treatments, shorn fasted, bellied fasted, woolly fasted and woolly not fasted. Shorn fasted lambs grew
12 g/d faster than woolly fasted lambs (P<0.05), but at similar rates to bellied lambs and woolly not fasted lambs. There were no
differences among treatments for carcase weight, meat yield or proportion of lambs killed at slaughter. The difference observed in
average daily gain between the shorn fasted and the woolly fasted lambs, and the lack of difference observed between shorn fasted
and woolly not fasted lambs, indicated that while shearing improved lamb growth rates, the weight loss due to fasting overnight
was not overcome by the increased growth rate associated with shearing. While there was no economic benefit associated with
lamb carcase weight or time to slaughter, at a wool price of $5.40 per kg clean, shorn lambs were still of a greater value to farmers
compared to lambs from all other treatments.},
