THE EFFECT OF Sauropus androgynus LEAF EXTRACT ON PERFORMANCE, EGG QUALITY AND CHEMICAL COMPOSITION OF EGGS
Abstract: The purpose of this
research was to produce the enriched eggs, but low in cholesterol content.
Forty eight layer chickens aged 72 weeks (strain Dekalb Warren) were
distributed into six treatment groups. One group of laying hens was fed diets
without Sauropus androgynus leaf extract (SALE) as the control, and another
five groups were fed diet supplemented to 9 g SALE, 18 g SALE, 27 g SALE, 36 g
SALE, and 45 g SALE/kg diet, respectively. Completely randomized design was
used in the present study. The experimental results showed that SALE
supplementation had no effect on egg production, feed intake, feed conversion
ratio, egg weight, yolk weight, albumen weight, shell egg, egg index, eggshell
thickness, and yolk index (P>0.05), but significantly affected Haugh Unit,
albumen index, yolk color, egg odor, egg taste, and yolk color (P<0.05). The
protein, fat, calsium, phosphor, kalium and iron contents of eggs did not change (P>0.05), but the
cholesterol content of egg was significantly reduced (P<0.05). In
conclusion, the supplementation of SALE did not enhance performance, but it
improve egg quality and its chemical composition.
