Study the effect of eggs incubation parameter through development of new experimental rig for IKTA quails species

Nowadays, machine is utilized as an alternative way to hatch eggs, however various temperature settings are used that result in different percentages of hatching between hatcheries. This study aims to investigate the effect of increasing incubation temperature, eggs movement type, and incubation time through a set of experimental rigs developed specifically to suit the experimental needs to determine the best eggs incubation parameter. Air flow and heat movements were simulated using Computational Fluid Dynamic Simulation and Modelling (CFX) to study the heat flow effect on hatchability before incubation construction. For case study, Institut Kemahiran Ternakan Ayam (IKTA) species used as test subjects. Incubation period took 17 days to completed. Setting temperature in each test run was different in the first day to the 14th and 15th to 17th day. First test run, the setting was 37 °C for 14 days then 38 °C for 3 days. In second incubation, 38 °C on the 14th day and 39 °C for 3 days, then third setting at 39°C on the 14th day and 40 °C for 3 days. Each setting was repeated three times, thus nine test runs were performed. With the same setting incubation temperature and humidity, two types of eggs movement were conducted in the same incubation chamber, 40 eggs were placed in 45 ° swing and 360 ° rolling. Unhatched eggs were opened and examined to see any abnormalities that may cause death of the embryo. From the data collected, temperature 37 °C14day 38 °C3day produced 89.17% eggs hatch, first eggs hatch in day 14 with average 5.42%, ends in day 16. By increasing 1-degree temperature, it decreased hatching to 84.17% with 6.67% hatch in day 14. By increasing 1 degrees, resulted just 76.67% eggs hatch, average 12.91% hatch in day 14. Thus, proved that by increasing temperature to 39°C was not as successful as 37 °C. Excessive temperature did not increase hatchability but speed up hatching time, it may cause embryonic mortality to egg development. Overall, experimental rig produces 83.16% hatching with 360 ° rolling produced slightly higher hatching average at 83.33% compared to 83% with 45° swing

Effect Of Incubation Temperature On Ikta’s Quail Breed With New Rolling Mechanism System / Mohd Badli Ramli...[et al.]

Successful of hatching rates in incubation quails IKTA(Institut Kemahiran Ternakan Ayam) may differ between each hatchery. There is numerous factor that influence embryonic development, among the parameter is temperature, humidity, air movement, eggs placement etc., This factor may lead to high percentage of embryo hatching and healthy DOQ (day one quail). Nine incubations were performed with 3 set of different temperature to examine the effect of different setting temperature. For eggs placement, eggs were turns using rolling mechanism 360° for every hour. Eggs obtained from local breeder with same age broiler flocks and stored for 1 to 4 days prior to intimate other commercial ideal condition. All in and all out system was used in all incubation set, eggs were place 40 piece in tray from day one until day 17. Overall it was determined that the best setting temperature is 37°c 14day then 38°c 3day that can produce average 89.17% hatching, average first hatch is in the end of day 15 complete hatch in 16 day. Temperature set 38°c 14day, then 39°c3day is 84.17%, average first hatch is day 15.5 end 16 day, not harmful compared to 39°c14day, then 40°c3day with 76.67% hatching with average first hatch is day 15.5 end 16 day. With increasing setting temperature, up to 39°c to 40°c still not successful as 37°c to 38°c, excessive temperature did not affect hatchability neither drastically speed up the hatching days, but can cause detrimental effect, embryonic mortality to eggs development. First hatch in the end of day 14, average in day 15, complete hatching in the end of day 16 , this is faster than other incubator in the market that average 17 day/ cycle. This new faster cycle cause by the consistent heat flow and humidity inside incubation chamber surrounding the eggs shell. In conclusion, ideal setting temperature 37°c 14day 38°c 3day is the best setting temperature to incubate IKTA species quails, with the efficiency of machine supply consistence temperature, humidity and eggs movement are the main parameter to ensure high hatching rates of IKTA quails
