Model of preserving poultry eggs using mist spray method of Paraffin oil in Hung Yen
The study was carried out to evaluate the effectiveness of poultry egg storage model by the method of paraffin oil mist spraying at 4 poultry farms (2 chicken and 2 duck farms) in Hung Yen. The results show that while implementing the preservation method, egg producers and business had to pay costs for cleaning and disinfecting eggs, buying paraffin oil with about 93 VND / egg for chicken eggs and 99 VND / egg for duck eggs, but in return, the loss rate was decreased (from 6-8% to 0.5%). Therefore, the total cost for 1 egg while preservation by this method was still lower than that without preservation (28 VND / AG1 chicken eggs and 24 VND /Japfa Brown chicken eggs, 30-31 VND / eggs for duck eggs). In addition, with this method of preservation, the egg can be kept fresh level up to 5 weeks compared to 1-2 weeks if not preserved in the summer while ensuring the quality of the sensory criteria, Haugh unit (duck eggs is 61.93-62.58, chicken eggs is 51.23-52.29), air chamber height (duck eggs is 4.23-4.35 mm, chicken eggs is 3.43-3.56 mm), microorganisms Salmonella (not detected in egg samples). With a total of 220.440 eggs preserved in the model (98.440 eggs of AG1, 122.000 eggs of Japfa Brown) and 213.950 fresh duck eggs, the total profit was about 133.9 million VND
