Growth Performance of Crossbred Calves Fed a Conventional and Total Mixed Ration with Varying Concentrate Level

Aim: The experiment was planned to investigate the effect of different concentrate roughage ratios and conventional feeding systems in total mixed ration on nutrient intake, water growth, feed conversion, cost crossbred dairy calves.
 Place Duration Study: present study carried out at Livestock Research Station, Anand Agricultural University, Anand, Gujarat for a period 84 days.
 Methodology: A 24 healthy (8 days old) preweaned (HF×Kankrej) calves were distributed randomly into four experimental treatments. T1 (control) group fed with system T2, T3, T4 groups TMR ratio 85:15, 75:25, 65:35, respectively. recorded.
 Results: daily, percent, metabolic body weight basis intake dry matter (DM), digestible nutrients (TDN), significantly (p<0.05) lower than calves. initial final (kg), height withers, heart girth, length (cm) did not differ among Total daily gain higher (65:35 ratio) compared feeding. requirement each kilogram live 65:35 (T4) control (T1). showed 21.81% (Rs 73.55/kg gain) as group.
 Conclusion: resulted reduced matter, TDN, better conversion convention (T1) 21.81 percent reduction cost.
