abstract
A study was conducted on 24 Murrah buffalo calves of either sex between 6 to 9 months of age at animal Farm, LUVAS, Hisar during the summer season from july 15, 2015 to october 15, 2015 (90Days). Experimental calves were divided into four treatments having six animals in each treatment viz. Loose housing system + 100% feeding level (T1), Loose housing system + 120% feeding level (T2), Conventional barn housing system + 100% feeding level (T3) and Conventional barn housing system + 120% feeding level (T4). There was significantly higher (p<0.05) temprature and temprature humidity index in conventional house than loose house. The analysis of variance revealed that there was no significance difference in increase in body measurement viz. body length, height, heart girth, abdominal girth due to housing system and feeding levels. However there was an increasing trend in body measurements in each group during the experimental period.
