Effect of Drinking Water Supplementation With Extract Fermented Tamarindus Indica By Saccharomyces Spp On Egg Production, Feed Digestibility And N-Nh3 Content In Excreta Laying Hens

The present experiment was conducted to determine effects of drinking water supplementation with extract fermented Tamarindus indica by Saccharomyces spp (Tamarin-Pro) on egg production, feed digestibilty, and N-NH3 in excreta of laying hens up to 54 weeks old. A total of 240 laying hens with an average initial body weight of 1674.91±18.52 g were randomly allotted into four drinking water treatments. The dringking water treatments included: drinking with 2% Tamarin-Pro extract (A); drinking water with 4% Tamarin-Pro extract (B); drinking water with 6%Tamarin-Pro extract (C); and drinking water as a control (D), respectively. Result showed that the Tamarin-Pro drinking water treatment had improved feed digestibility compared with control treatments (p<.05). The egg mass in Tamarin-Pro treatments B and D were greater than that in control treatment (p<.05). Moreover, Tamarin-Pro extract decreased significantly (p<.05) N-NH3 in excreta of birds. In conclusion, fermented Tamarindus indica by Saccharomyces spp (Tamarin-Pro) extract supplementation improved egg mass and nutrient digestibility in laying hens and decreased N-NH3 in excreta of hens.
