BACKGROUND: Pre-pubertal nutrition managements are considered essential for animal health, optimizing production and reproductive performance in livestock. OBJECTIVES: In this study, the effects of dietary low and high energy and protein provisions on body growth, blood metabolites and inherent safety index were investigated in pre-pubertal Kurdish female lambs. METHODS: We fed 40 healthy Kurdish female lambs (30±8.6 days old and weighing 10.2±3.4 kg) were randomly divided into one of two experimental diets in pre-weaning period: high energy and protein (HEP, 2.50 Mcal ME/kg dry matter (DM) and 148 g CP/kg DM) or low energy and protein (LEP, 2.02 Mcal ME/kg DM and 87 g CP/kg DM). At the time of weaning, one half of lambs from each group was randomly separated and assigned to HEP or LEP. So there were four treatment groups in post-weaning period: H-H (HEP pre- and post-weaning); H-L (HEP pre-weaning and LEP post-weaning); L-H (LEP pre-weaning and HEP post-weaning) and L-L (LEP pre and post-weaning, control group). Treatment effects on dry matter intake, milk intake, serum metabolite profiles, inherent safety index and growth were examined. RESULTS: Pre-pubertal plane were significantly affected above mention parameters at post- weaning period (P

Objective: To investigate the reproductive performance and milk quality to nutrition pre-pubertal plane in Kurdish female kids.Methods: Forty Kurdish female kids [aged (28.0±6.6) d and weighted (7.56±1.10) kg] were assigned randomly in pre-weaning period to one of two practical diets: low quality diet (LQD) [87 g CP/kg dray matter (DM) and 2.02 Mcal ME/kg DM], and high quality diet (HQD), (148 g CP/kg DM and 2.50 Mcal ME/kg DM). At weaning, from each group, one half of kids was separated randomly and allocated to LQD or HQD. Consequently, in post-weaning period, there were four treatment groups including: LQD pre and post-weaning (L-L), control group and LQD pre-weaning and HQD post-weaning (L-H); HQD pre-weaning and LQD post-weaning (H-L), HQD pre- and post-weanin (H-H). From 30 to 180 d of age, body weight and DM intake were determined every 2 wk.Results: Results showed that the HQD treatment enhanced body weight and DM intake during pre-weaning period, in comparison with the LQD treatment (P
