Abstract

The additional supplementation of shell grit as calcium source improves the egg shell quality. The objective of the experiment was to study the effect of supplementation of shell grit on egg production, hatchability and economics of desi bird in backyard system rearing. The Front Line Demonstration (FLDs) was conducted at Naraikinaru and Mangalapuram Village in Namagiripettai block of Namakkal District in Tamilnadu. In this village 10 backyard desi bird farmers were selected, each farms grouped into two (T1: Farmers practice (FP) was not supplemented shell grit and T2 supplemented with shell grit @ 5-7 g/bird/day with the size of 2 mm in the evening), each group consist of 3 desi birds reared under backyard. The average egg production per bird per cycle was significantly (P<0.05) higher in shell grit supplemented group compared to control. The supplementation of calcium from shell grit significantly (P<0.05) decreased cracked egg percentage results in hatchability was significantly (P<0.01) increased under natural brooding compared to control. BCR was higher in shell grit supplemented group compared to control

Conclusion

The present study revealed that, additional supplementation of shell grit increased the egg production, hatchability and improved the livelihood of the backyard poultry farmers. In future, effect of supplementation of shell grit on survivability of chicks upto one month may be studied
