Abstract:

This study was designed to evaluate the effect of HimLay® on egg lay, egg production, ovarian activity, and serum LH levels in White Leghorn (WL) BV 300 nonlayer birds. A total of 20 BV 300 nonlayer birds aged 28 weeks were allocated equally into two groups viz., G1 and G2 (10 birds/group). G1 and G2 served as normal controls and the HimLay® supplemented group, respectively. Both groups were raised on normal commercial layer mash feed, and G2 was concurrently supplemented with HimLay® at a recommended mixing ratio of 500 g/ton for 8 weeks. Hen-housed egg production and pelvic bone width parameters were assessed weekly. Serum LH levels were estimated on day 0, week 4, and week 8. Ovarian activity was assessed at termination of the study. The resulting egg production data depicted that egg production was initiated from WL BV 300 nonlayer birds as early as from the first week of HimLay® treatment, and egg production was increased throughout the treatment period following supplementation of 500-g/ton HimLay®. Furthermore, almost 80% of BV 300 nonlayer birds supplemented with 500-g/ton BV 300 could produce eggs at par with BV 300 layer bird standards on week 35. Following supplementation of 500-g/ton HimLay®, serum LH levels, initiation of ovarian functions, and follicle development have improved. Supplementation of 500-g/ton HimLay® on BV 300 nonlayer birds helps in converting nonlayer birds to layer birds, and hence, usage of HimLay® could play a crucial role for the farmer of an average poultry farm to make profit.
