“…Results obtained indicated the superiority of fish meal over WHWM. In a similar study, Abiola and Onunkwor (2004) reported decreased feed intake with decrease in levels of fish meal in layers diets. Body weight gain of cockerels decreased with increase in the levels of dried un-hatched incubators eggs in the diets (Abiola, 1999).…”

SUMMARYA study was conducted in which processed whole hatchery waste meal (WHWM) replaced fish meal (FM), protein for protein, in broiler diets at 0, 10, 20 and 30% levels. There were 45 birds per treatment and 15 birds per replicate. The feeding trial which lasted for 42 days, was carried out at the Poultry Unit, Agricultural Research Council, Glen. Chemical analysis of the two test ingredients indicated that WHWM had higher contents of ash (18.12%) and ether extract (23.94%). However, crude protein content of FM was 73.18% while that of WHWM was 42.26%. Calcium-phosphorus ratio was 16.6:1 for WHWM as against 1.5:1 in the FM. Broilers fed with diet 2 had highest values for feed intake (118.25 g/bird/day) and weight gain (50.16 g/bird/day) while those fed with diet 3 were superior in efficiency of feed utilization (2.31). Results obtained for carcass traits decreased with increase in the levels of WHWM in the diets. Broilers fed with control diet had highest mean values for eviscerated weight (2.20 kg) and dressing percentage (77.86%). Values recorded for abdominal fat and internal organs (liver, lungs, heart and gizzard) did not show any particular trend. Similarly there were slight variations in the results obtained for blood parameters. Cost of feed intake/bird decreased with increase in the levels of WHWM in the diets.It can be concluded from the results of this study that 10% of FM can be replaced with WHWM in broiler diets without adverse effects on growth and carcass traits. This approach of turning waste into a valuable product will provide alternative protein and calcium sources in broiler diets and solve the problem of hatching waste disposal in the hatchery industry.

“…The lowest feed cost /kg weight gain of R8.69 was recorded for broilers fed on diet three. Several studies have documented the use of hatching waste in poultry diet as means of reducing feed cost (Babiker et al, 1991;Abiola, 1999;Abiola, 2001;Abiola and Onunkwor, 2004). …”

“…The use of hatchery by-products in broilers (Babiker et al, 1991), cockerels (Abiola, 2001) and layers (Abiola and Onunkwor, 2004) have been demonstrated in previous studies. Recycling large quantities of hatchery waste to agricultural lands raises some serious nutrient management and biosecurity issues (Deshmukh and Patterson, 1997).…”

Handling and Treatment of Poultry Hatchery Waste: A Review

2011

View full text Add to dashboard Cite

A literature review was undertaken to identify methods being used to handle and treat hatchery waste. Hatchery waste can be separated into solid waste and liquid waste by centrifuging or by using screens. Potential methods for treating hatchery waste on site include use of a furnace to heat the waste to produce steam to run a turbine generator or to use an in line composter to stabilise the waste. There is also potential to use anaerobic digestion at hatcheries to produce methane and fertilisers. Hatcheries disposing wastewater into lagoons could establish a series of ponds where algae, zooplankton and fish utilise the nutrients using integrated aquaculture which cleans the water making it more suitable for irrigation. The ideal system to establish in a hatchery would be to incorporate separation and handling equipment to separate waste into its various components for further treatment. This would save disposal costs, produce biogas to reduce power costs at plants and produce a range of value added products. However the scale of operations at many hatcheries is too small and development of treatment systems may not be viable.
