EFFECT OF ADDING LACTIC AND ACETIC ACIDS TO THE DIED IN PROD PERFORMANCE OF LAYING HENS

Abstract

This study was carried out at the poultry farm of Animal Production Dept./ College of Agriculture/ University of Diyala during the period from 1/9/2015 to 1/1/2016 to study the effect of adding organic acids (lactic acid and acetic acid) individually in the diets of laying hens and their impact on the productive performance of the chickens. In this study had used 150 hens laying Lohmann brown breed aged 18 weeks, and were weighed individually and distributed randomly at the age of 19 weeks on five treatments with three replicates (10 chickens/ replicate). The first treatment represented control, the second and third included add 0.2% and 0.4% of lactic acid respectively, and the fourth and fifth had included the addition of 0.2 and 0.4% of acetic acid respectively. The results showed that all productive traits were significantly increased compared with control treatment. 34 weeks), as it outperformed added treatments was significantly (P <0.01) in the rate of egg production (% Hen day production) and the weight and mass of eggs. As moral differences between the treatment and comparison coefficients were not added when calculating feed rates of the consumer in terms of production and more at the expense of the overall rate, while the birds showed all supplementation on treatments, significant difference (P< 0.01) in converting food into eggs weight coefficient.
