Using Unmarketable Egg Powder as Protein Supplement in Pre Ruminant Lamb Milk Replacer

Abstract

The present study was carried out to assess whether the powder from eggs unfit for human consumption can be recovered as a protein supplement in milk replacer of pre ruminant lamb. A total of 96 lambs were divided into 2 groups and received 2 diets based on milk: a control and an experimental milk containing 20 % of egg powder, from 24 h after birth to 4 weeks of life. Both diets are repeated 5 times, 10 batches using each 9 or 10 lambs per repetition. The hematocrit of lambs is measured at the second and fourth postnatal week. It is stand out from this study, a considerable gap between the 2 diets for lambs for all Zoo technique measured parameters: body weight, weight gain, consumption of milk powder, feed efficiency and hematocrit. This difference is at the expense of the experimental group for which it can be concluded that the unfit egg powder is not suitable for pre ruminant lambs, given various digestive disorders observed during the experiment.
