Abstract

The purpose of this study was to determine the effect of temperature and duration of heating on the interior quality of chicken eggs from crosses between Kedu chickens and Bangkok chickens. This research is a biological research using a 2x4 factorial Completely Randomized Design (CRD). The first factor is temperature (P) (27 and 32 0C) and the second factor is heating time (T) (0, 6 and 12 hours) where each treatment uses 5 chicken eggs. The results of statistical analysis showed that temperature had no significant effect (P>0.05) on egg weight loss, egg yolk index and egg white height. The heating time had a very significant effect (p<0.01) on the yolk index and egg white height but had no significant effect (p>0.05) on egg weight loss. The interaction between the two treatment factors gave no significant effect (p>0.05) on egg weight loss and egg yolk index but gave a very significant effect (p<0.01) on egg white height. Egg weight loss in this study ranged from 0.46 -0.50%; Egg yolk index ranged from 0.32-0.39 and egg white height ranged from 5.35-7.45mm. The conclusion of this study is that the temperature and duration of the heating process can reduce the interior quality of chicken eggs from a cross between a Kedu chicken and a Bangkok chicken

Abstract

The purpose of this study was to determine the effect of watermelon seed flour supplementation in feed on the interior quality of native chicken eggs. This research is a biological research using Completely Randomized Design (CRD) with 4 treatments and 5 replications. Each treatment used 5 chickens. The results of statistical analysis showed that watermelon seed flour supplementation in feed had a very significant effect (p<0.01) on the egg yolk index and egg white height and had an insignificant effect (p>0.05) on the egg index. The conclusion of this study is that watermelon seed flour supplementation can improve the interior quality of native chicken eggs. The best supplementation dose at 0.10%.

Abstract

The purpose of this study was to determine the effect of heating before incubation on the quality of native chicken hatching eggs. This study used 200 eggs from native chickens. This research is a laboratory research using Completely Randomized Design (CRD) with 4 treatments and 5 replications. Each treatment used 10 hatching eggs. If statistical analysis shows a significantly different or very significant effect, it will be continued by using Duncan's test. In this study, the results showed that heating of hatching eggs before incubation had a very significant effect (p<0.01) on fertility and hatchability, but had an insignificant effect (p>0.05) on weight loss of hatching eggs. The average egg weight loss in this study ranged from 0.00-0.10%, fertility 70.94-83.15%, embrio mortality 15-40% and hatchability ranged from 60-85%. Based on the results of the study, it can be concluded that the heating of the hatching eggs before the eggs are put into the incubator can reduce the quality of the hatching eggs. The longer heating time causes the lower quality of hatching eggs.
