Respon Ayam yang Mempunyai Pengalaman Infeksi Ascaridia galli terhadap Infeksi Ulang dan Implikasinya terhadap Produktivitas dan Kualitas Telur
Abstract
The aimed of this research was to find out the effect of infection experience of Ascaridia galli on
productivity and eggs qualities. The research was held in Helminthology Laboratory, Veterinary Faculty and Animal
Production Laboratory, Faculty of Animal Husbandry, Bogor Institute of Agriculture. The research was based on a
Randomized Completely Design. The treatments were P0 = without infection ; P1 = have been infected with 200 infective
eggs A. galli every chick every week ( 8, 15, 22 and 30 days old chick) and re-infected with 500 infected eggs at 18 weeks
old; P2= chicks with no infection experience at starter period, and infected with 500 infected eggs at laying period. The
productivity and quality of eggs were examined. The results showed that infection experience of Ascaridia galli influenced
the layer productivity and their eggs qualities. The experience of A. galli infection several times with light dosage at starter
period (P1) made the layers more resistance to re-infection by the parasite in the laying period. Consumption and
conversion of feed, eggs weight, shell thickness and calcium concentration of P1 was not significant difference with control
group (P0). First A. galli infection in layer period in group without experience of A. galli infection before (P2), have showed
that, compare with the control group (P0), the feed conversion of P2 was 15.78% higher (P
