Abstract: Thhis study was made to determine the relationship of the weight of the native chicken egg to fertility hatchability under artificial incubation. The experiment started from October to November 1973. Coverin a period of three months. It was conducted at the Animal Husbandry Department of Don Severino Agricultural College, Indang, Cavite. 100 hundred eggs of native chicken were used in this experiment. Two trials of replications were made. On the first trial 60 days were used while the second trial made use of 40 days only. Eggs in the incubator were turned two or three times in order to have an even incubation to determine the number of fertile and infertile eggs. On the forteenth day of the incubation the second candling was done to determine the eggs processing dead embryos. The results mtay be summarized as follows: The average weight of the eggs on the first trial ranged from 41 to 43 grams and 38 to 40 on the second trial. The highest percentage of the fertile eggs were under the range 32 to 34, 44 to 46, 50 to 52, 53 to 55 grams, with 100 percent fertility each. The lowest number of fertility eggs were found to be under the range 47 to 49 grams with 66.7 percent fertility. The total percentage of fertility in the first candling was 63 percent. The highest number of infertile eggs were under the range 38 to 40 grams. The total number of infertile eggs was 17 percent Similarly greater number of infertile eggs were found to be under the range of 38 to 40 grams. The same as in the first candling the possibility of obtaining the dead embryo on that range was also very great since they represented the greatest number of samples used. The total number of dead embryo was 16. Thhere were 46 eggs that were hatched on the 21st day of incubation which represented the percentage hatchability while 21 eggs remained unhatched after 21 days. The highest percentage hatchability however was under the range 29 to 31 grams and 50 to 52 grams each having 100 percent. There was an indication that the weight of eggs has has nothing to do with fertility and hatchability of the eggs of the native chicken.

Thhis study was made to determine the relationship of the weight of the native chicken egg to fertility hatchability under artificial incubation. The experiment started from October to November 1973. Coverin a period of three months. It was conducted at the Animal Husbandry Department of Don Severino Agricultural College, Indang, Cavite.

100 hundred eggs of native chicken were used in this experiment. Two trials of replications were made. On the first trial 60 days were used while the second trial made use of 40 days only. Eggs in the incubator were turned two or three times in order to have an even incubation to determine the number of fertile and infertile eggs. On the forteenth day of the incubation the second candling was done to determine the eggs processing dead embryos.

The results mtay be summarized as follows:

The average weight of the eggs on the first trial ranged from 41 to 43 grams and 38 to 40 on the second trial.
The highest percentage of the fertile eggs were under the range 32 to 34, 44 to 46, 50 to 52, 53 to 55 grams, with 100 percent fertility each. The lowest number of fertility eggs were found to be under the range 47 to 49 grams with 66.7 percent fertility. The total percentage of fertility in the first candling was 63 percent.
The highest number of infertile eggs were under the range 38 to 40 grams. The total number of infertile eggs was 17 percent
Similarly greater number of infertile eggs were found to be under the range of 38 to 40 grams. The same as in the first candling the possibility of obtaining the dead embryo on that range was also very great since they represented the greatest number of samples used. The total number of dead embryo was 16.
Thhere were 46 eggs that were hatched on the 21st day of incubation which represented the percentage hatchability while 21 eggs remained unhatched after 21 days. The highest percentage hatchability however was under the range 29 to 31 grams and 50 to 52 grams each having 100 percent.
There was an indication that the weight of eggs has has nothing to do with fertility and hatchability of the eggs of the native chicken.
