Abstract: BERNARTE, SHEELA MAE S. and LIWAG, KRISTINE IDA L. Specific Gravity and Hatchability Rate of Chicken Eggs (Lohmann Strain). Research Study. Science High School College of Education. Cavite State University, Indang, Cavite. April 2007. Adviser: Dr. Alvin William Alvarez. The study entitled "Specific Gravity of Eggs and Hatchability Rate in Lohmann Strain of Chickens" was conducted to determine the specific gravity and hatchability of eggs and to describe the classifications of hatched eggs. Different sets were prepared which include Set A with a specific gravity of 1.090, Set B with specific gravity of 1.085, Set C with specific gravity of 1.080 and Set D with specific gravity of 1.075. One thousand eggs were divided into four batches. The first batch was soaked into the first salt solution with specific gravity of 1.090 or Set A. This procedure was repeated to all the remaining solution until it reached the container with lowest specific gravity (1.075). The eggs that floated in different sets were classified and incubated for 21 days. After 21 days, the chicks that hatched from these eggs were counted and segregated per group. The results showed that among the four sets, Set A with a specific gravity of 1.090 has the highest hatchability rate of 59% and has the highest standard hatched eggs while Set D with a specific gravity of 1.075 has 0% hatchability. Therefore, the study proved that the higher the specific gravity, the higher the hatchability rate of eggs.
