Abstract
Forty female Zaraibi goats (during the last month of pregnancy) in the 3rd and 4th sea7sons of lactation were used to study the effect of folic acid on milk production, some rumen and blood parameters and changes of live body weight of Zaraibi does. Forty
does were divided randomly into four equal groups (10 females each). Animals in groups G1,G2 and G3 received 0, 2 and 6 mg folic acid/kg body weight(BW) daily, respectively in their diets. But, G4 received one intravenous injection of 4 ml saline solution containing 40 mg folic acid, weekly. Feeding allowances of Zaraibi does were calculate according to NRC (1981).
The obtained results showed that using folic in Zaraibi does rations improved milk yield by 8.8, 11.6 and 22.1% forG2,G3 and G4, respectively compared with the co7ntrol(G1),and the improvement was significant with G4. However, milk composition was not significantly affected by folic acid. The results of rumen parameters of Zaraibi goats showed that pH value, ammonia-N and volatile fatty acids (VFA’s) were not significantly differed among the groups. Moreover, no remarkable effects of folic acid were observed on hemato-biochemical parameters. Feed utilization efficiency, based on DM, was better with G4 then followed by G3 and G2 compared with the control ration (G1).
Accordingly, it could be concluded that using folic acid had positive role on improving milk yield for lactating Zaraibi goats without any adverse effect on milk composition as well as rumen and blood parameters. It improved also fee7d utilization.
