Abstract
The study was carried out at the Livestock Farm, Rajasthan College of Agriculture, MPUA&T, Udaipur (Rajasthan) in two experiments to effect of feeding formaldehyde treated til cake on the performance of lactating crossbred cows and heifers.
EXPERIMENT I :
Fifteen lactating crossbred cows in early stage of lactation were divided into three groups of five animals each and randomly allotted to three dietary treatments as follows :
All the animals were offered sorghum stover ad lib. + 10 kg green berseem. In treatment T1 animals were given untreated til cake, while in treatment T2 and T3 FA treated @ 1.0 g FA/100 g CP and FA treated @ 1.5 g FA/100 g CP respectively as a source of protein in the concentrate mixture was given. The daily DMI, DMI/100 kg body weight and per kg W0.75 were significantly (P<0.01) higher in T3 as compared T2 and T1 groups, however, no-significant difference between T2 and T1 groups.
The average daily CPI, CPI/100 kg body weight and CPI per kg W0.75 were significantly (P<0.01) higher in T3 groups as compared T2 and T1 groups however, non-significant difference between T2 and T1 groups. A similar trend were also observed in daily DCPI, DCPI per 100 kg body weight and DCPI per kg W0.75. A same trend also observed in daily TDNI, TDNI per 100 kg body weight and TDNI per kg metabolic body size. The VWI was significantly (P<0.01) higher in T3 and T2 groups than T1 groups, however, non-significant difference in T2 and T3 groups. The VWI/kg DMI and TWI/kg DMI was significantly (P<0.01) higher in T3 than T2 and T1 groups. No significant difference in VWI/kg milk yield and TWI/kg milk yield among the treatment groups.
The digestibility coefficient of all nutrients except CF and EE had non-significant difference between the all treatments. However, CF and EE was significantly (P<0.01) higher in T3 as compared to T2 and T1 groups, respectively. The daily milk yield was 8.73, 9.80 and 10.21 kg in T1, T2 and T3 groups, respectively. The daily milk yield was significantly (P<0.01) higher in T3 as compared T2 and T1 groups, but non-significant difference between T2 and T3 groups. The fat per cent, was significantly (P<0.05) higher in T3 group as compared to T2 and T1 groups, however similar in T2 and T1 groups. The feed conversion efficiency was not influenced by formaldehyde treated til cake in the ration. The feed cost per kg milk yield was Rs. 6.33, 5.92 and 6.15 in T1, T2 and T3 treatments, respectively.
EXPERIMENT II:
Fifteen crossbred heifers were divided into three groups of five animals each and randomly allotted. In three dietary treatments as follows :
All the animals were offered sorghum stover ad lib. + 2 kg green berseem. In treatment T1 animals were given untreated til cake, while in treatment T2 and T3 FA treated @ 1.0 g FA/100 g CP and FA treated @ 1.5 g FA/100 g CP respectively as a source of protein in the concentrate mixture was given. The daily DM intake, CP intake, DCP intake and TDN intake were non-significant among all dietary treatments. A similar trend were also observed in DM intake per 100 kg body weight, CPI /100 kg body weight, DCP intake / 100 kg body weight and TDN intake / 100 kg body weight. The VWI and TWI were significantly (P<0.05) higher in T3 treatment than T2 and T1. However, non-significant differences were found between T1 and T2 groups. The differences in digestibility coefficient for DM, OM, CP and NFE except CF and EE were non-significant among the different treatments. However, CF and EE digestibility was significantly (P<0.05) higher in T3 than T1 groups. But non-significant differences were found in T3 and T2 one hand and T2 and T1 other hand. Average body weight gain was significantly (P<0.05) higher in T3 compared to T2 and T1 groups, however T2 group significantly (P<0.05) body weight gain than T1 groups. The feed conversion efficiency of DMI and TDNI and CPI per kg body weight gain were non-significant among the dietary treatments. The cost of feeding per kg live weight gain was lowest in T3 group (27.79) followed by T2 (30.85) and T1 (32.70) groups.
Based on the results found it is concluded that formaldehyde treatment @ 1.5 (FA/100 g CP) of til cake should be taken up by the feed industry on a commercial scale for manufacturing bypass protein, as the feeding of treated til cake proved beneficial in improving milk yield and total fat in lactating crossbred cows and growth rate in heifers.
