The 2009 issue of the Sheep and Goat Research Journal is complete with the addition of the following two articles.
- Post-weaning Management of Lambs Alters Subsequent Feedlot Performance and Tissue Deposition written by R. R. Redden, R. W. Kott, L.M.M. Surber, J. A. Boles, A. W. Layton and P. G. Hatfield. Backgrounding lambs on forage-based diets after weaning may provide producers with alternatives to traditional marketing of lambs directly to feedlots. The objective of the paper was to evaluate feedlot performance of lambs from different backgrounding treatments. Seventy-two crossbred lambs were randomly assigned to one of four backgrounding treatments: 1) drylot ad libitum access to 80:20 alfalfa:barley pellets; 2) cool-season, grass-paddock grazing; 3) unweaned, dormant-range grazing; and 4) weaned, dormant-range grazing.
- Substituting Distillers Dried Grains for Cottonseed Meal in Lamb-Finishing Diets: Growth, Wool Characteristics, and Serum NEFA, Urea N, and IGF-1 Concentrations written by J. K. McEachern, T. R. Whitney, C. B. Scott, C. J. Lupton and M. W. Salisbury. This paper looked at the effects of replacing cottonseed meal (CSM) with corn distillers dried grains (DDG) on growth, wool and serum NEFA, urea N and IGF-1 concentrations. The results indicated that DDG can replace all the CSM in lambfinishing diets without negatively affecting growth, efficiency of gain or wool characteristics and can potentially reduce cost of feedokg-1 gain.
