To assess influence of feeding milk replacer alone and with probiotic (Lactobacillus acidophillus) supplementation on pre-weaning growth performance and nutrient utilization, 48 Malpura lambs of 7d of age were distributed randomly into three equal groups. Lambs were maintained individually under feeding regimens of ad libitum creep mixture along with green and dry roughage (C-0; Control), and the same supplemented with milk replacer alone (C-MR), or milk replacer in combination with live probiotic culture (C-MRP). Lambs were allowed to suckle their respective dams in the morning and evening till 91d of age, and fed ad libitum green leaves of Prosopis cinereria and dry cowpea hay. Pre-weaning performance of lambs in terms of weaning weight (20.7 kg, P=0.009), average daily gain (ADG; 183.1g, P=0.003) and feed conversion ratio was higher (P=0.019) in C-MRP lambs as compared to control (C0). The DM intake was significantly (P=0.026) higher in C-MR and C-MRP lambs due to higher plane of nutrition. Rumen pH was lowest (P=0.023) in C-MR lambs. Ammonia concentration decreased and total VFAs increased with milk replacer feeding in both C-MR and C-MRP groups. Level of propionic acid increased and acetic acid decreased in C-MR and C-MRP lambs. Rumen ciliate protozoa population (x10 ⁴ /ml) decreased (P=0.022) in C-MR (91.3) and C-MRP (95.4) group lambs than in C-0 lambs (122.8). Milk replacer feeding in C-MR and C-MRP lamb improved (P < 0.05) the nutrient digestibility. Thus, milk replacer feeding during pre-weaning has significant influence on weight gain, feed efficiency and nutrient utilization; however, the influence of probiotic feeding on lamb growth needs further studies.
