LAYING PERFORMANCE OF ItikPINAS (Anas platyrynchos Linnaeus) AS AFFECTED BY GARLIC (Allium sativum) POWDER IN DRINKING WATER

Abstract

The laying performance, egg quality, egg classification, and income over feed cost of Improved Philippine Mallard duck (ItikPINAS) were examined as influenced by garlic powder in drinking water for six weeks. Forty-eight ducks (42 females and 6 males), aged thirteen months, were divided into two treatments: one with the supplementation of 1g garlic powder (GP) in every 4 liters of water (250 ppm) and the other without garlic powder (control) in drinking water. Each treatment consisted of three replicates, with eight ducks (7 females and 1 male) per replication. The results showed that there was a significant (P = 0.03) difference in average egg weight where higher values were attained by ducks with GP (77.67 g ± 0.64) than the control (75.64 g ± 0.43). The supplementation of garlic powder in drinking water, however, did not affect egg production, feed intake, FCR, egg mass, livability, egg quality, and egg classification. However, the ItikPINAS with GP in drinking water had numerically higher income over feed cost than those without. GP in drinking water can be considered in raising ItikPINAS. Further studies on increasing the level of GP and long feeding duration also merit consideration to substantiate the findings.
