Online published on 11 January, 2012. Abstract An experiment was conducted on 18 crossbred heifers, which were divided into 3 groups of 6 animals each and allotted to three dietary treatments. All the animals were provided wheat straw ad lib. + 5 kg green berseem. During treatment, T1 animals were given untreated GNC, whereas T2 and T3 FA were treated at 0.5 g FA/100 g CP and at 1.0 g FA/100 g CP, respectively, as a source of protein in the concentrate mixture was given. Effects of different dietary treatment groups on average daily DM, CP, DCP and TDN intake were found to be non-significant. The over-all maximum temperature in routine managements treatments was 34.88°C, which was recorded during the experimental period and the minimum temperature recorded was 17.14 oC. The average weekly relative humidity in the morning and evening ranged from 33.0 to 90.0% and 10.0 to 54.0%, respectively and the overall values ranged from 21.5 to 63.5%. The average RH was 30.77% higher in the morning as compared to the evening. Protected protein did not influence the morning and evening rectal temperature. The respiration rate of heifers was significantly (P<0.05) higher in T3 as compared to T1. There was a non-significant difference between T2 and T3 on one hand and T2 and T1 on the other. The morning pulse rate was significantly (P<0.05) influenced by the treatments. It may be inferred that feeding of formaldehyde -treated GNC increases the supply of essential amino acids without any adverse effect on rumen function, causing significant increase in the growth rate in crossbred heifers.
