Summary

Studies were conducted on two calves and a pregnant female captured from the forest to assess the feed utilization, growth pattern and milk composition in Mithun (Bos frontalis), a rare bovine species of north-eastern India. The DMI, kg/100 kg body weight was 0.05 with DM and OM digestibility of 56.95 ± 3.68 and 58.46 ± 3.51 percents, respectively, in calves. The growth was more during the May to October months, however, the average growth of 181.26 ± 23.51 g day-1 was obtained during the year on grazing. The Mithun was not a milk yielder, but became accustomed to milking. Fat content in milk varied from 6.8 to 7.8%. The total solids, protein, lactose, ash and solid not fat (SNF) were estimated at 18.0, 4.9, 5.0, 0.8 and 10.7% respectively with COB negative at 4°C. The birth weight of the male calf was estimated at 22.0 kg, and an average growth of 325.14 g day-1 was determined in 214 days with maximum weight gain during the first two months of age.

Résumé

Des études ont été réalisées sur deux génisses et une femelle gravide capturées dans la forêt, pour évaluer l'efficacité de leur alimentation, le rythme de croissance et la composition du lait de Mithun (Bos frontalis), qui est une rare espèce bovine du nord-est de l'Inde. Le DMI, kg/100 kg de poids corporel chez les génisses, était de 0,5 avec une digestibilité de DM et OM égale à 56,95,±3,68 et 56,46 ± 3,51%, respectivement. La croissance était supérieure pendant la période de mai à octobre; cependant, la moyenne de croissance de 181,26 ± 23,51 g jour-1 a été obtenue pendant l'année au pâturage. Le Mithun n'est pas un animal à lait, bien que habitué à la traite, et la teneur en gras du lait varie de 6,8 à 7,8%. On a estimé les résidus totaux solides en protéine, lactose, cendre et solide non gras (SNG) à des niveaux de 18,0; 4,9; 5,0; 0,8 et 10,7%, respectivement, avec un COB négatif à 4°C. Le poids à la naissance du mâle a été estimé à 22,0 kg, et une croissance moyenne de 325,14 g jour-1 a été déterminée pour une période de 214 jours avec un maximum de gain de poids pendant les deux premiers mois de vie.
