Abstract
The negative energy balance (NEB) is a common issue for dairy buffalo cows during the transition period which is the time around three weeks before and after parturition. The effect of rumen protected glucose (RPG) on metabolic attributes as well as milk production was studied using sixteen clinically healthy buffalo cows with average body weight of 450-
550 kg at third parity selected from Mehallet Moussa Experimental Station (Kafr El-Sheikh, North Delta), which belongs to the Animal Production Research Institute, Ministry of agriculture, Egypt. The buffalo cows were divided randomly into two groups (n=8 per group).The first group fed the basal diets without supplementation and served as a control, while the second group was received the same diet supplemented with 250g RPG/ head/ day for 42 days started at three weeks pre-partum and lasted three weeks postpartum. The metabolic profiles of buffalo cows were affected by the dietary treatment. The concentrations of serum TG (triglycerides), TC (total cholesterol), glucose, insulin, and IGF-1 (insulin like growth factor-1) were higher in RPG-treated group than the control group (p<0.05), however GGT (Gamma-glutamyl transferase), AST (aspartate transaminase), ALT (alanine transaminase), NEFAs (non-esterified fatty acids) and BHBA (β-hydroxyl butyric acid) were significantly (p<0.0001) shrunk in RPG-treated groups in relative to the control group. Milk traits including total milk yield, daily milk yield, and lactation period were significantly improved (p<0.05) in RPG-treated group compared to the control, the significant differences were calculated to be +470.25, kg, +1.78 kg, and +28.86 days, respectively. Finally, during the transition period, RPG supplementation increased the concentration of serum TG and TC which were sufficiently used as energy yielding nutrients for improving milk yield and protecting against ketosis.
