This study aims to determine the level of skim milk in the best coconut water that can maintain the quality of spermatozoa of native chickens during storage at 5oC. Semen was divided into five tubes (without diluents, diluents with skim milk levels 0%, 6%, 8% and 12, liquid Semen was then stored at 5oC. Observations of motility and viability were carried out at 0, 12, 24 hours, 36, and 48 hours. The results showed that the use of various diluents had a very significant effect (P <0.01) on the motility and viability of chicken spermatozoa at 12 hours of storage. The highest motility of spermatozoa was found in coconut milk diluent treatment with milk level skim 6%, and skim milk level 9% at 0 o'clock, 12 o'clock and 48 o'clock storage, while the highest motility at 24 o'clock and 36 o'clock was at treatment with skim milk level 6% Viability of spermatozoa at 0 o'clock does not differ between treatments but during storage, in general, the viability of spermatozoa can survive better in diluents with skim milk levels of 6% and 9% Conclusion of this study is coconut water Diluent with skim milk level of 6% and 9% can maintain the quality of chicken spermatozoa better during storage 48 hours at a temperature of 5oC.

This study aimed to findthe best combination of glucose concentration with the type of extender to maintain progressive motility and viability of Native Rooster spermatozoa, which stored for 48 hours at 5oC. This study used a completely randomized design (CRD) factorial pattern of 4 x 3. The first treatment was a different type of extender: LE (lactated ringer egg yolk), LS (lactated ringer skim milk), CE (coconut water egg yolk) and CS (coconut water skim milk), while second treatment was glucose concentration (20mM, 50mM, and 80mM).  Native Rooster semen diluted with a ratio of 1:10, thensperm was stored in the refrigerator (5oC). Progressive motility and viability were observed at 0, 24, 48, and 72 hours. The results showed the type of extender treatment had a very significant effect (P <0.01) on the viability of spermatozoa, which were stored 24-hour. The treatment of extender type, glucose concentration, and interaction of extender type with glucose concentration had a very significant effect (P <0.01) on the quality of spermatozoa, which were stored 48 hours and 72 hours. The highest progressive motility of spermatozoa was maintained up to 46.67 ± 2.89% and spermatozoa viability up to 74.68 ± 4.51% in WE 80mM glucose extenders, so the conclusion of this study is the combination of egg yolk coconut water with 80mM glucose is the best extender to maintain progressive motility and viability of spermatozoa of Native Rooster which is stored for 72 hours at 5oC.

This study aims to determine the ratio of productivity of chicken and Bangkok female maintained on an extensive system. A total of 4 female chickens and using four Bangkok females in this study. Keeping chickens from DOC until first production (± seven months). The maintenance system from DOC for up to 2 weeks is intensified using heating aid after two weeks of extensive maintenance. After the production (layer) is done recording (productivity recording) that is egg weight, number of eggs per period, the age of early parent spawn, and weight of mother early spawn as parameter observed in this research. Data result of the analysis is processed using T-test. The result showed that productivity of chicken and Bangkok female saw from the age of fresh parent eggs and weight of initial parent spawn. Chickens earlier lay eggs compared to chicken Bangkok, but the parent weight at the time of spawning is higher in Bangkok female chickens when compared to females.

The purpose of this study was to determine the relationship of broiler quail’s initial body weight which is fastened at post-hatch to growth and attainment the last body weight. One hundred thirty-five quails aged 12 post-hatch had kept in a cage plot which had prepared based on a completely randomized design with 3x3 factorial pattern and three replications which each replication consisted of 5 quails. The first factor is body weight post-hatch (B) consist of B1 = 5.1 – 6.0 g (light), B2 = 6.1 – 7.0 g (medium) and B3 = 7.1 – 8.0 g (heavy), the second factor is the duration of fasting post-hatch (P) consist of P1 = 24 hours, P2 = 36 hours and P3 = 48 hours. The observed parameters to fasting were feed consumption, body weight, and feed conversion. The result of this study is the quail with light early body weight (5.1-6 g) post hatch showed that the lightest last body weight is related to the value of feed conversion. Accession good performance of quail can be reached by access feed approximately 24 hours.
