Economic assessment of potential efficiency gains in typical lamb production systems in the alpine region by using local resources
Publication date: Available online 13 February 2020Source: Small Ruminant ResearchAuthor(s): C. Gazzarin, N. El BenniAbstractThe alpine region is very suitable for sheep farming, which keeps the landscape open and produces meat by using local resources. However, the market has more potential than currently realised, but the profitability of lamb production needs to be improved. Management changes would allow efficiency gains and could be implemented on farms in the short or medium term. Thus, based on traditional high-quality forage management in the Swiss alpine region, we analysed the profitability of lamb production sys...

Comparative performance of Dorper and Rambouillet ewes on West Texas range
The objective of this experiment was to compare overall productivity between Dorper (n = 96) and Rambouillet (n = 100) ewes in West Texas commercial production conditions. Ewes originated from private flocks and were mated to produce terminal cross or purebred lambs, depending upon the year. These ewes generated 1,091 records of reproductive performance and lamb weights. Ewe traits included weight at the beginning of the fall breeding season, fertility (ewes that gave birth per ewe exposed), condition score, lambing interval, and stayability to 9 yr of age. Mixed linear models included flock of ...
