  • This work was conducted to evaluate the hatching and growing performance of Korean native chicken (KNC) 3 strains crossbred. A total of 360 female pullets were produced from $\times$ (A), CL $\times$ C (B), CG $\times$ C (C) and CW $\times$ C (D) crossbred kept in National Institute of Animal Science, Korea. Hatchability of A, B, C and D were 69.8, 70.7, 75.5 and 77.4%, respectively. Livability were not significantly different by 20 weeks among 4 strains. Body weight B was high compared to other strains at 20 weeks. The feed conversion ratio of 4 strains was no significantly different among strains at 20 weeks. These results suggested the basic data that needed to develope the new strains.

  • This study was carried out to measure the environmental related parameters from two types of swine houses. Indoor temperature, relative humidity, carbon dioxide level, ammonia concentration and emission were measures every 2 minutes from each house with portable monitoring units. Carbon dioxide concentration balance was used to estimate the ventilation rates of the different houses. Daily ammonia concentrations in the growing-finishing and farrowing houses ranged from 2 to 17 ppm and 6 to 15 ppm respectively. The daily ammonia emission rate from the manure averaged 4.37 g/h$\cdot$500 kg from growing-finishing house and 4.82 g/h$\cdot$500 kg from the farrowing house. The above findings proved that summer season was associated with higher ammonia emission rates due to higher ventilation rate and ambient air temperature.
