EFFECT OF DIFFERENT LEVEL OF TUAF SACCHA IN THE DIETS ON EGG YIELD AND QUALITY OF LAYING HENS

Abstract

A study was carried out to determine the impact of TUAF Saccha meal to the egg yield and quality of Dominant layer. 270 hens at 23 weeks old were randomly divided into three groups of 30 hens each. This experiment was repeated three times. The groups were corresponded to three dietary treatments (ĐC, TN1, TN2) containing respectively 0, 2, 4 grs yeast/ kg of feed. The experiments lasted in 10 weeks. The results showed that the addition of TUAF - Saccha yeast improved the laying rate and egg yield. The laying rate is 76.50%, 76.97%, 80.65% respectively in the ĐC, TN1, TN2. Egg productivity was 5.36, 5.39, 5.65 eggs/hen/week were recorded at the plot of ĐC, TN1, TN2. Feed consumption/10 eggs in ĐC, TN1, TN2 were 1.47, 1.47 and 1.40 kg respectively, but there was no significant difference (P> 0.05 ). In terms of egg quality, there was no significant difference in weight, shell thickness and HU units among different yeast proportions (P> 0.05). The results of the experiment showed that TUAF Saccha yeast improved some important parameters to egg yield and quality of Dominant chicken.
