Effect of feeding ration containing raw or heated soyabean seeds on productive and reproductive performance of buffaloes at early lactation

Abstract: Eighteen lactating buffaloes at the second lactation were used to evaluate the effect of feeding rations containing raw or heated soyabean seeds on productive and reproductive performance of buffaloes at early lactation. The buffaloes were assigned to three similar groups (six animals each). The buffaloes were fed rations containing similar ingredients with the same proportions of concentrate feed mixture, berseem, yellow corn and rice straw. The control group received a ration containing no supplementary soyabean, the second group received ration containing raw soyabean seeds (RSB) and the third group received ration containing heated soyabean seed (HSB).
The total mixed rations with added soyabean seeds (SBS) had higher content of ether extract (EE) and crud protein (CP); however, nitrogen free extract (NFE) and fatty acid (FA's) were lower compared with the control ration. The magnitude of changes in body weight during the experimental period was greater in group had rations containing either raw soyabean or treated soyabean than control group. Both RSB and HSB rations cause improvement of rumen parameters. Feed ration containing soyabean seeds improved circulating progesterone (P4), cortisol and prostaglandin (PG F2a in blood. These hormones caused safety parturition. Added soyabean seeds resulted in significantly (P<0.05) high of fat corrected milk (FCM).
Milk fat percentage and yield protein percentage and yield and total solids and yield were higher with added soyabean seeds (SBS) to buffaloes rations. Added RSB or HSB improved the reproductive performance of lactating buffaloes. Number of service per conception and days open were reduced. Eating behavior clearly showed that supplemented (SBS) had significant (P<0.05) effect on diurnal behavior activity of total eating time and decrease ruminating time. The total eating time and ruminating period /Kg DM intake expressed the greatest when the buffaloes fed HSB followed by RSB.
Ration containing both raw or heated caused improvement of sexual behavior and a good sings of estrus than control groups. The hormone pattern (cortisol and PG F2a) of treated groups was higher than that of control groups. This profile eased management at parturition and placenta fall-down. As results of feed SBS to early lactating buffalos, fed conversion and economical cost were improved. The cost of producing 1.0 Kg milk was reduced. reproductive traits were improved.
Finally, fed RSB and HSB improved both the production and reproduction performance of lactating buffaloes at early lactation. It is recommended to use RSB or HSB as sources of fat and energy in early lactation of lactating buffaloes to reduce loss of body weight and the negative effect of adding natural fat to the rations.
