Indonesia is currently in the top 10 of the world's poultry meat and egg producers. Poultry house in Indonesia is the main key in fulfilling the need for consumption of animal protein. Broiler and Layer types are the type of chicken that dominates the poultry farm sector in Indonesia, this is a serious threat to food sovereignty in Indonesia because Indonesia has not been able to provide Broiler and Layer grand parent stock as breed on several neighboring countries by doing import grand parent stock (GPS). So the objective of this research is to obtain the hybrid chickens with high egg and meat productivity yet still had the superiority of meat taste and strong body resistance like local chicken or native chicken. This Research conducted in Pusat Informasi Agroteknologi (PIAT) UGM di Kalitirto, Berbah, Sleman, D.I.Yogyakarta. In this study Back Crossess were conducted between F1 Kamper roosters and Layer hens. The growth rate of BC1 Kamper  is lower than Layer and F1 Kamper and based on the statistical analyses, there are no differences of growth rate between BC1 Kamper and parental. Hybrid Chicken BC1 Kamper resulted from ♀ F1 Layer And ♂ F1 Kamper crosses has diverse  phenotypic variations quantitative and qualitative data, the phenotype characters of BC1 Kamper such as ♂ F1 Kamper and the growth rate such as ♀ F1 Layer.

This study aims to compare the quality of  Friesian Holstein (FH) dairy cows in Bendul Merisi, Surabaya (Lowlands) and Nongkojajar, Pasuruan (Highlands), with the physical quality standard of fresh milk which is the national reference or SNI. This study used 60 samples of cow's milk, 30 samples from Bendul Merisi, and 30 samples from Nongkojajar. The sample was tested in the laboratory using the fat content and specific gravity test, the data obtained were calculated using the T-test formula. The data obtained from the average fat content test in Nongkojajar was 3.3685%, and the average fat content in Bendul Meisi was 4.8003%. The average density at Nongkojajar is 1.024767 mg / dl, the average density at Bendul Merisi is 1.28067 mg / dl. Based on the results of statistical calculations resulted in a significant difference (P <0.01) in the fat content test, statistical calculations resulted in a significant difference (P <0.01) in the specific gravity test.
