This study was conducted to determine the reproductiveÂ performance of various breeds of Sentul chicken.Â The present research was assigned in an experimental model with a completely randomized design (CRD), with 5 breeds of Sentul chicken were created as treatments, namely Abu Sentul chicken = SA; Batu Sentul Chicken=SB; Emas Sentul Chicken=SE; Debu Sentul Chicken=SD; and Geni Sentul Chicken=SG. Each treatment was repeated 5 times with 4 females and 1 male birds each, thus the total number of chickens were 100 females and 25 males with an average initial female weight was 1,336.05 Â± 84,99 g and male weight wasÂ 2,050.53 Â± 121,78 g.Â The experiment was conducted forÂ 14 weeks started from 20 week old until 34 week old. Variables measured were spermatozoa production, fertility, and hatchability. Data were subjected to analysis of variance and HSD test. Results showed that various breeds of Sentul chicken had no significant effect (P>0.05) on spermatozoa production, and had significant effect (P<0.05) on fertility and hatchability. It can be concluded that spermatozoa productionÂ of various breeds of Sentul chicken are relatively similar, while fertility and hatchability of Emas chicken was lower than that of Abu Sentul chicken and Batu Sentul Chicken.

The research entitled â€œIdentification of Factors Contributed toÂ Beef Cattle Reproductive Disorders in Ogan Komering Ulu Timur Regency (OKU Timur) of South Sumatra Province in UPSUS SIWAB Program 2018â€ was done on Semendawai Suku III and Semendawai Timur, OKU Timur regency, South Sumatra on October 10th until November 10th 2018. The purpose of this research is to identify the factors contributed to reproductive disorders of beef cattle, mapping the factors that affect reproductive disorders of beef cattle and generate strategies to improve reproductive performance of beef cattle in OKU Timur Regency. The targets in the study are 40 beef cattle breeders, 2 inseminators and 2 employees of the Local Office of Fisheries and Livestock Services of OKU Timur Regency.The research was done by survey, the method used was qualitative modeling with the Causal Loop Diagram (CLD). The variables observed in the study were variables related to reproductive performance consisted of Body Condition Score (BCS), Calving Interval (CI), Service per Conception (S/C), Conception Rate (CR) and variables related to factors indicated to have contribution to reproductive disorders such as farmer characteristics, resources owned by farmers and resources possessed by inseminators. The results showed that reproductive disorders of beef cattle in OKU Timur Regency included ovarian hypofunction, endometritis, pyometra, systolic ovary, silent heat, vulvitis, vaginitis, mummification and placental retention. The identified factors contributed to reproductive disorders are low quality and availability of feed, low breeders' knowledge, absence of postpartum treatment, limited medical supplies and quantity, unstandard technical implementation of artificial insemination, cross breeding of heifer, insufficient inseminator facilities. Strategies that can be done to improve the reproductive performance of beef cattle is to increase the role of the government in providing superior feed seeds and assisting by Universities; increasing the number of medicalsupplies and facilities, equip inseminator with sufficient facilities, and technical insemination and increasing the intensity of extension services to improve farmers' knowledge and utilization of potential agricultural waste with technology.

The application of oxytocin induction to milk production in relation to the performance of kids in dairy goats had been carried out in the "PEGUMAS" dairy goat farmer group Gumelar District, Banyumas. This activity aimed to increase milk production and kid performance through the induction of the hormone oxytocin in dairy goats. The approach method was designed in two stages: the first stage carried out the socialization activities and demonstration of techniques for applying IPTEKS, and the second stage applied hormonal technology in the form of oxytocin hormone induction in dairy goats. The material used was dairy goat parity I aged 1.5 - 2 years allocated into 2 groups of 10 individuals each. Group I was dairy goat experiment not induced with the oxytocin hormone as the control. Group II was dairy goat experiment induced with the oxytocin hormone at a dose of 1 ml (10 IU) intramuscularly before milking. Milk production was measured morning and evening as daily milk production in milliliters (ml). Milk was given to the kid of each parent. The kid's performance was measured based on the daily weight gain of the kid during the study. Overall, the application of science and technology could be adopted by farmers, and oxytocin-induced dairy goat milk production (503.2 ml) was significantly higher (P<0.05) than control (305.4 ml) with an increase of 64.77%, with a positive level of correlation (r = 0.45) and contributed 19.83% to the kids daily body weight gain.

Motilitas dan Abnormalitas Spermatozoa Ayam Kampung dengan Pengencer Ringer Laktat-Putih Telur dan Lama Simpan pada Suhu 5 C selama 48 Jam Aras Prasetiyo Nugroho; Dadang Mulyadi Saleh

Penelitian bertujuan untuk mengetahui pengaruh interaksi antara rasio pengencer ringer laktat-putih telur dan penyimpanan selama 48 jam pada suhu 5 C terhadap motilitas dan abnormalitas spermatozoa ayam kampung. Penelitian menggunakan Rancangan Acak Kelompok (RAK) dengan pola faktorial 6 x 5 dengan faktor R yaitu rasio pengencer ringer laktat dengan putih telur (r0=kontrol, r1=ringer laktat, r2=ringer laktat 75% + putih telur 25%, r3=ringer laktat 50% + putih telur 50%, r4=ringer laktat 25% + putih telur 75%, dan r5=putih telur) dan faktor T yaitu penyimpanan selama 48 jam pada suhu 5 C (t1=1 jam, t2=12 jam, t3=24 jam, t4=36 jam, t5=48 jam) masing-masing perlakuan diulang empat kali. Hasil penelitian menunjukkan bahwa masing-masing faktor memberikan pengaruh terhadap motilitas dan abnormalitas spermatozoa ayam kampung (p<0,05). Hasil menunjukkan motilitas terbaik spermatozoa ayam kampung dihasilkan oleh perlakuan ringer laktat dengan penyimpanan selama 12 jam (82,5%). Selanjutnya, abnormalitas terbaik spermatozoa ayam kampung (8,5%) dihasilkan oleh perlakuan ringer laktat dengan penyimpanan selama satu jam. Persentase abnormalitas spermatozoa dari semua perlakuan menunjukkan kurang dari 20%. Dari hasil penelitian ini maka dapat disimpulkan bahwa spermatozoa ayam kampung yang diencerkan dengan ringer laktat dengan penyimpanan pada suhu 5 C dapat digunakan untuk inseminasi sampai 12 jam.Kata kunci: spermatozoa, ayam kampung, pengencer, ringer laktat, putih telur (Motility and Abnormality of Kampong Rooster Sperm Diluted with Different Kinds of Extenders and Stored at 5 C for 48 Hours)The purpose of this research was to determine the interaction effects between types of extender and storage time on sperm motility and abnormality of kampong rooster. This experiment was implemented following a 6x5 factorial design, in which the ratio between Ringer Lactat and egg albumen i.e. r0= control; r1=ringer lactat; r2=75% ringer lactate+25% egg albumen; r3=50% ringer lactate+50% egg albumen; r4=25% ringer lactate+75% egg albumen, and r5=egg albumen as the first factor and storage time which consisted of t1=1 hour; t2=12 hrs; t3=24 hrs; t4=36 hrs as the second factor. Each of the treatment was replicated four times. Results indicated that the types of extender and storage time had no significant interaction (p>0.05) on the percentage of motility and abnormality of kampong rooster sperm. However, each of the treatment had a significant effect (p<0.05) on the motility and the abnormality of kampong rooster sperm. The highest value of sperm motility (82.5 %) was obtained from a ringer lactat extender. This sperm motility value has a significant difference (p<0.05) from the 5 other types of extender. The lowest value of sperm abnormality (8.5%) was obtained from an hour of storage time. This value has a significant difference (p<0.05) than the 4 other treatments. However the percentage of abnormal sperm from all the treatments is less than 20 percent. It could be concluded that kampong rooster sperm which diluted with ringer lactate stored at 5 0C can still be utilized for Insemination not until 12 hours of stored.Keywords: sperm, kampong rooster, extender, ringer lactatee, egg albumen
