Abstract
We investigated the effects of water supplemented with Saccharicterpenin and photosynthetic bacteria (PSB) on egg production, egg quality, serum immunoglobulins, and digestive enzyme activities of Jinyun ducks. A total of 400 healthy Jinyun ducks (all aged 58 wk) were randomly allotted to five treatments, with four replicates per treatment and 20 ducks in each replicate. The animals were fed a standard diet for 15 d and the experimental diet for 55 d. Experimental design is as follows: negative-control group C1 was given no supplementation, and control group 2 was given pool water (PW) with added PSB but not Saccharicterpenin. Test groups T1, T2, and T3 were given the same amount of PSB in the PW and varying levels of Saccharicterpenin in drinking water. Results suggest that PSB combined with Saccharicterpenin had beneficial effects on the average egg weight, feed to egg ratio, laying rate, and amylase activity, but some bad effects on the yolk color score. Additionally, PSB alone can increase the average egg weight.
