Evaluation of dietary Curcoma longa L. effects on fertility, embryo development, hatchability, quality and blood indices of newly hatched chicks in breeder native hens

This experiment was conducted on breeder native hens (West Azerbaijan). For this purpose، two hundred and forty native hens (23 weeks old) were used in four experimental groups. The birds of each group were put in six replicate pens. Furthermore، a rooster was put in each cage for investigate the fertility and hatchability of the hens. The birds of different groups were received the different levels of 0، 0. 25، 0. 50 and 1 percent turmeric rhizome powder. After the feeding the experimental diets for five weeks، 20 eggs were collected from each cages and used for incubation. There were no significant differences between the treatments for hatchability، fertility، embryo mortality and chick quality between treatments (p>0. 05). Turmeric had no effect on blood total protein (p>0. 05) but the highest turmeric consumption caused the increased blood cholesterol (p<0. 05). Furthermore، blood lactate dehydrogenase and glutamate oxaloacetate transaminase activities were not affected by turmeric (p>0. 05). However، all the turmeric levels decreased blood glutamate pyruvate transaminase activity as compared to control (p<0. 05).
