ABSTRACT
The aim of this study was carried out to investigate the effect of using bee bread extract (BBE) as feed additive on productive a performance as milk yield and its composition of maternal goats during suckling period. As well as the growth performance of suckling kids and immunity status were studied. Eighteen Zaraibi goats averaged post–partum live body weight (LBW) 38.73 kg and aged 3-4 years as well as a number of born kids (twin) were divided randomly into three similar groups, where each one was allocated on the following dietary treatments. The control ration (T1) consisted of concentrate feed mixture (CFM) 70% + roughage 30% were the roughage portion was consisted of 25% berseem hay (BH) + 5% rice straw (RS), according to NRC (2007), with 5.0 ml of distilled water / head / daily throughout 90 -d. trial period. While the second and third groups (T2 and T3) were received the same control ration plus orally a dose of BBE 2.5 and 5.0 ml / head / daily throughout the trial period days, respectively. Results showed that the all digestibility coefficients and nutritive value as TDN and DCP for T3 or T2 were significant (P < 0.05) improved as compared with the T1 (control ration). Also, animals received BBE (T3 or T2) recorded higher (P < 0.05) average changes of body weight, BCS of maternal goats and enhance (P < 0.05) fed conversion and daily gain of their kids, milk yield and its components, classification of immunoglobulins in suckling milk, some blood serum parameters and economic efficiency than those the control ration (T1). However, differences were not significant (P>0.05) for both T3 and T2 among them. The present study indicate that the animals fed BBE as fed additives (T3 or T2) at concentrations of 2.5 and 5.0 ml / daily during critical period of suckling months could be caused positively effect on productive performance, suckling milk yield and it quality which reflected on health and growth rate of kids.
