AbstractThis study was conducted from 16/1/2017 to 23/2/2017 to show the effect of the different storage period on the specifications of the specific chickpeas by exposing the eggs to sporadic incubation processes during the storage period of the broiler eggs ROSS 308. The eggs were brought from Al-Manar Company for poultry production and breeding - Diyala and were in the form of two separate experiments where the duration of the first experiment was 29 days and the second 37 days.
The first experiment 7 days storage, and the second 14 days storage included four transactions storage only, storage with pre-incubation + pre-incubation for short periods SPIDES, storage with pre-incubation + heat stimulation and storage with pre-incubation for short periods SPIDES + thermal stimulation. The results showed significant differences (P<0.01) in the body mass, where the first and third treatments were superior to the rest of the experimental factors, while there were no significant differences in the rest of the external specimens of the white hatches of the eggs stored for 7 days. The results did not show any significant differences the internal characteristics of the white hatched eggs were stored for 7 days only in the ratio of the weight of the liver to the body weight, which exceeded the second treatment on the rest of the experiment.
The external characteristics of the eggs from the eggs were stored for 14 days. The weights and body mass in the first treatment exceeded the rest of the experimental parameters. The internal characteristics of the chicks also exceeded the first treatment in the body weight on the rest of the experiment. The weight of yolk to the body weight by the first and second treatments on the rest of the experiment, the ratio of weight of the liver and intestines to the weight of the body has exceeded the fourth treatment on the rest of the experiment. This study showed no effect of pre-incubation of 6 hours and pre-incubation for short periods during the storage of SPIDES in addition to thermal stimulation 39.5% in days 16, 17 and 18 of brood, on the specifications of the quality chick and the characteristics of internal chicks regardless of storage time.
