Abstract:
The present experiment was carried out to assess the effect of mineral mixture supplementation on productive and reproductive performance of dairy animals in Chittorgarh district of Rajasthan. The data was collected through personal interviews conducted using a pre-tested, well-structured interview schedule, from 180 dairy farmers. Dairy farmers were divided into two groups viz., beneficiary respondents (n=90) and non-beneficiary respondents (n=90). Animals from beneficiary respondents group were supplemented with the mineral mixture, while animal from non-beneficiary respondents group were not supplemented with the mineral mixture. The study revealed that mean value of productive traits of beneficiary respondents dairy cattle viz., lactation length (279.69 days), total lactation milk yield (1542.26 lit.) and average milk yield/day (5.52 lit.) were found significantly (p≤0.01) higher than non-beneficiary respondents dairy cattle and no significant differences in milk fat and milk SNF % between the beneficiary and non-beneficiary respondents dairy cattle. Similarly mean value of productive traits of beneficiary respondents dairy buffaloes viz., lactation length (289.85 days), total lactation milk yield (2087.39 lit.) and average milk yield/day (7.20 lit.), peak yield (8.17 lit.) were also found significantly higher (p≤0.01) as compared to non-beneficiary respondents dairy buffaloes. Reproductive traits of beneficiary respondents dairy cattle viz., service period (113.87 days), dry period (124.92 days) and postpartum estrus days (95.15 days) were found significantly (p≤0.01) lower and conception rate (66.34%), heat period (23.39 Hrs.) higher than the non-beneficiary respondents dairy cattle. Mean value of reproductive measures of beneficiary respondents dairy buffaloes viz., service period (125.95 days), dry period (128.17 days) and postpartum estrus days (97.56 days) were also found significantly (p≤0.01) lower and conception rate (61.88%), heat period (21.09 Hrs.) higher as compared to non-beneficiary respondents dairy buffaloes.
