DOI: 10.1080/00288233.2020.1840399
Abstract: ABSTRACT Ewe lamb live weight at first mating (7 months of age) is positively associated with reproductive performance and led to the recommendation of a minimum mating live weight of 40 kg. This experiment examined the… read more here.

DOI: 10.1080/1828051x.2018.1431964
Abstract: Abstract A comparative slaughter trial was conducted to estimate the net trace element requirements of Dorper × Hu ewe lambs. Thirty-five ewe lambs with an initial body weight of 33.52 ± 0.56 kg, were used. Seven ewe lambs were randomly… read more here.

DOI: 10.1093/tas/txz156
Abstract: Abstract The decision on which ewe lamb to retain versus which to sell is likely to vary by producer based on personal preference. What is not known, however, is if any commonality exists among producers… read more here.

DOI: 10.3168/jds.2018-14648
Abstract: Nutritional programming caused by feed restriction during the early life may counteract the profitability of the dairy sheep farm. However, most studies have been focused exclusively on the prenatal period, and scarce information regarding the… read more here.
