Abstract
A study was carried out to find the effect of feeding probiotics and synbiotics on milk yield, milk constituents, haematological, serum biochemical parameters and cost per kg milk production in lactating Murrah buffaloes at Buffalo Research Station, Venkataramannagudem
Eighteen Murrah buffaloes in their early lactation were assigned into three groups of each six buffaloes on basis of average daily milk yield in a completely randomised design (CRD). Group-I was control, Group-II was supplemented with probiotics @ 30 gm/animal/day and Group-III was supplemented with synbiotics @ 20 gm/animal/day for a period of 3 months. The milk yield, milk constituents, haematological, serum biochemical parameters and cost per kg milk production were recorded during the experiment.The average daily milk yield was significantly higher (p<0.05) in probiotic and synbiotic supplemented groups (9.45 kg/day in probiotic and 11.17 kg/day in synbiotic against 8.97 kg/day in the control group). Significantly (p<0.05) higher milk fat percentage values were recorded in probiotic and synbiotic supplemented group (9.1% in probiotic and 9.42% in synbiotic against 8.26% in control groups). Total solids (%) was significantly (p<0.05) higher in probiotic and synbiotic supplemented groups (19.54±0.19 in probiotic and 19.95±0.24 in synbiotic against 18.69±0.05 in the control group). No significant effect of probiotic and synbiotic supplementation was evident on milk SNF, milk protein, and milk lactose percent throughout the experimental period.
No significant effect of probiotic and synbiotic supplementation was evident on different haematological parameters viz., total leucocyte count (x103 /μL), total erythrocyte count (x106 /μL), haemoglobin (g/dL), packed cell volume (PCV %), mean corpuscular hemoglobin (fL), mean corpuscular volume (pg). There was no statistically significant difference on serum biochemical parameters like serum cholesterol, serum glucose, serum calcium and serum phosphorous.
The cost per kg milk production is Rs. 22.85, Rs. 22.84 and Rs. 20.47 in control, probiotic and synbiotic groups respectively, which saves Rs. 2.38 per day for one kg milk production in synbiotic supplemented group.
The present research concluded that probiotic supplementation @ 30 gm/animal/day and synbiotic @20 gm/animal/day increased milk yield and milk fat. Supplementation of synbiotic decreased the cost of milk production in Murrah buffaloes.
