On the 30th of January 2017 the first production cycle of the Modern Broiler Learning Centre (MBLC) started. Unfortunately, due to limited supply of good quality day-old-chick only the tunnel house was used. A total of 8,059 DOCs were supplied by independent breeding farms from Cianjur. The chicks were checked for quality control and placed into the newly built house. The chicks were divided into 2 groups and spread out over the two floor which already were preheated by gas brooders. Water was provided via manual drinkers and feed via manual day-old-chick feeders.
The body weight gain during the first week was close to the breed standard (Cobb 500). From day 14 onwards body weight growth was 5 to 8% higher than the breed standard. Although the body weight growth had excellent values, the temperature of the chicks was too low and they were avoiding the middle area of the house. Based on close observation it was concluded that the wind speed was too high. Based on this conclusion the wind speed was reduced by opening the side curtains slightly (about 10-15 cm from the top) and as a result, a few hours after this was done the birds were spread more uniformly over the house.
The installation of an advanced water treatment system had a positive effect on the hardness of the water (reduced) and in turn on the performance of the birds in terms of water and feed intake (increase).
Please note that the health programme applied in the MBLC is mostly based on herbal products which stimulate the immune system, enhance broiler appetite and protect liver function.
Harvesting of the birds was carried out on three days, from day 31 until day 35. The average age was 32.7 days and the final body weight was 1.97 kg, 6% higher than the breeder standard. The feed conversion rate was comparable with the breeder standard (1.50) but mortality (3.9%) was considered too high and has to be improved.
In general, the partners are satisfied about the production performance of the first cycle however more attention will need to be put on the DOC quality control, ventilation settings, and water quality to bring the MBLC to a maximum level.
