Effect of vitamin E,C, Selenium and Zinc supplementation on reproductive performance of two local breeds of chickens under hot climate condition
Abstract: This experiment was carried out during summer 2002 at Sids Poultry Research Station, Animal Production and Research Institute, to study the effect of supplementing 0.5 ppm Se, 100mg/kg Zn, 100 IU Vit. E and 1000ppm Vit. C to diets on reproductive performance of Dokki- 4 and Bandara hens under hot climate condition at summer season (ambient temperature ranged from 22 -38Dc and the humidity from 35 -60 %) . The results obtained can be summarized as follows:
1. Hens fed diets supplemented with Se had higher egg production rate (E.P).than other treatments fed Vit.C,E, and Zn had significantly higher egg production than those fed control diet.
2.Adding Se, Vit. E, C and Zn to diets increased egg weight more than control diets.
3.Supplementing diets during hot climate condition with Zn, Vit.E, Se and Vit.C improved final body weight
4.Hens fed diets supplemented with Se. consumed higher feed with superior feed conversion rate
5.Dokki4 hens had higher egg production (E.P.) , percentage of body weight change and conversion of feed to eggs than Bandara.
6.Using Se.,Zn., vit.E, and C improved hatchability and fertility percentages for both Dokki 4 and Bandara egg than control.
7.Supplementing Vit. C increased hatched-chick weight more than other groups.
8.Dokki 4 males had higher fertility % than Bandara, whereas Bandara eggs had superior hatchability percentage.
9. Adding Se to hen diets increased egg weight and yolk weight %, while Vit. E and C improved ylok index, also supplementing each of Vit. E, Se. and Zn improved shell quality.
10.Dokki 4 hens laid eggs with high yolk weight % , yolk index with high shell quality than Bandara eggs which laid heavier eggs with high albumin weight percentage.
11.Supplementing Se, Vit. E. and C, resulted in significant improvement in semen quality traits. Se. increased ejaculate volume, motility of the sperm and livabiliby, but decreased percentages of dead and abnormal sperms.
12.Dokki-4 males had higher volume ejaculate and livability percentages than Bandara ones.
