Abstract

A study was conducted to investigate the effects of lactic acid bacteria serum (LABS) supplementation of drinking water on the egg production performance of Philippine mallard ducks (AnasplatyrhynchosL). A total of 72 56-weeks old mallard ducks were used in the experiment. Ducks were distributed to three treatments following completely randomized design (CRD) with three replicates per treatment and eight ducks per replicate pen. Lactic acid bacteria serum (LABS) with 2.8 x 107 cfu/mL of Lactobacillus sp. was used in the study. The treatments are drinking water with the following levels of LABS: 0%, 1% and 2%. The experiment lasted for 90 days. Commercial duck layer feeds was given to the animals. Results showed that supplementation of probiotic LABS in water had no effect (P>0.05) on feed and water consumption, egg production, egg weight, yolk weight, body weight gain, feed efficiency and mortality of mallard ducks within the 90 days period. However, supplementation of probiotic LABS with 1% and 2% inclusion levels improved (P<0.05) the egg shell thickness from period 31-60 days and 1-90 days. It also improved yolk color from period 61-90 days (P<0.05).
