The effect of safflower oil (Carthamus Tinctorius L.) and inositol supplementation on egg production

Abstract

The study aimed to examine the effect of safflower oil and inositol supplementation in a feed on egg production performance and feed conversion ratio of Sentul chickens. The research was conducted using experimental methods based on a completely randomized design (CRD). The materials used were 81 female Sentul chickens aged 16 weeks, which were divided into 9 groups of feed treatment, namely R0: control feed; R1: feed containing 0.5% safflower oil; R2: feed containing 1% safflower oil; R3: feed containing 0.5% inositol; R4: feed containing 1% inositol; R5: feed containing 0.5% safflower oil and 0.5% inositol; R6: feed containing 0.5% safflower oil and 1% inositol; R7: feed containing 1% safflower oil and 0.5% inositol; R8: feed containing 1% safflower oil and 1% inositol. The variables measured consisted of egg production, egg weight, egg mass and feed conversion ratio (FCR). Data were analyzed by analysis of variance. The results showed that the treatment had no significant effect (P <0.05) on all measured variables. The average number of eggs, egg weight, egg mass and FCR for 8 weeks of observation were: 66 ± 9 eggs; 37.31 ± 2.19 g; 16.44 ± 3.31 and 2.26 ± 0.37 The conclusion of this study was the supplementation of safflower oil and inositol with a concentration of 0.5% -1% in feed has not been able to improve the performance of egg production, and the feed efficiency of Sentul chickens.
