KADAR HORMON TESTOSTERON, LIBIDO, DAN KUALITAS SPERMA KAMBING BLIGON, KEJOBONG, DAN PERANAKAN ETAWAH

The aim of the study was to investigate the comparison and correlation among testosterone concentrations, libido, and sperm quality of Bligon, Kejobong, and Etawah cross-bred (PE) bucks at the similar of age, feed, and season. Samples used were 9 bucks (3 Bligon, 3 Kejobong, and 3 PE) in ±18 months of age. Testosterones was measured by enzyme-linked immunosorbent assay (ELISA) method. Libido observation were quantified at the first time to sniff, mount, and finally ejaculation. Sperm was collected by using artificial vagina, and correlation between testosterones, libido, and sperm quality was measured. Results showed that Kejobong�s testosterone in the morning (12.00±6.56 ng/ml) was significantly different with PE (6.82±4.18 ng/ml) (P�0.05), whereas Bligon�s testosterone in the morning (9.23±4.73 ng/ml) was similar with Kejobong and PE. The best time of Kejobong�s libido was in the morning (6.77±5.9

PENGARUH PAKAN BERBASIS PRODUK KETELA POHON TERHADAP KINERJA REPRODUKSI (PADA PEMBERIAN SECARA FLUSHING) DAN KINERJA PRODUKSI KAMBING KEJOBONG

2. 0 The purpose of this experiment was to evaluate the reproduction and production performance of Kejobong goats throuh usage of feed bases on the cassava products by stressing on the hormone concentration and profile on pre and post mating and of the role of calpain and calpastatin activities in meat tenderness. Does were 2.50 to 3 years of old with the average of initial live weight was 26.6 kg � 1.71kg as many as 20 heads to be used for studying of the reproduction and productivity performance. Does were 0 � 2.50 years of old with the average of initial live weight was 23.80 � 24.20kg as much as 20 heads to be utilized for investigating on the activity of calpain and calpastatin of meat. All animals were randomly assigned into two treatments, namely: non-flushing and flushing. Both treatments were each repeated 10 times. Composition and nutrient content of the two treatments, namely: non-flushing: 48.84% grasses, 30.23% cassava leaves, and 20.93% Glyrisidae immaculata (9.7% C

KADAR HORMON ESTROGEN DAN PROGESTERON PADA KAMBING BLIGON YANG DIBERI PAKAN DAUN PEPAYA

PENGARUH BANGSA TERHADAP KINERJA REPRODUKSI INDUK SAPI POTONG DI KABUPATEN BLITAR

The aim of this research was to determine the effect of cows breed in performance at small-holder cattle farm in 4 regions from 150 respondent in Blitar, such as Talun, Srengat, Ponggok and Udanawu regency. The research was conducted in October 2013. This research was carried out by survey method to get primary and secondary data. The variables were respondent�s identity, respondent�s experience, first age mating, first mating age, post partum mating, post partum estrus, service per conception, conception rate, non return rate and calving interval. The data was tabulated and counted for average, standard deviation and percentage. The data was analyzed by a Completely Radomized Design (CRD) One Way Classification and if the result is significant its continue with Duncan test. The result showed that average of maerial performance PO, SIMPO, LIMPO and BX manner to fist mating age (month) 23.82±4.3, 24.36±5.06, 19.18±3.75, 21.85±4.1

The aim of the study was to investigate response, behaviour, cycle of estrous and profile estrogen hormone of bali cattle (Bos sondaicus) were synchronized by PGF2α. Material samples were 9 Bali cattle at ±3 years of age and the rate of weight were 313,67±20,66 kg. Research method such a

PERBEDAAN KUANTITAS DAN KUALITAS SPERMA ANTARA AYAM KETAWA DAN AYAM PELUNG PADA PENAMPUNGAN SPERMA PAGI DAN SORE HARI

This study aims to compare the quantity and quality fresh sperm in the morning collection and afternoon collection of Ketawa chicken and Pelung chicken. Used six chickens aged ± 24 weeks consisting of 3 Ketawa chickens and 3 Pelung chickens. Collection of sperm for each chicken was done 10 times with a frequency of 2 times a week, using the massage method. Macroscopic examination of sperm include volume, color and odor, consistency and pH, whereas microscopic examination include motility, viability, abnormality, and the concentration of spermatozoa. Data were analyzed using analysis of variance using a completely randomized design with a types x time of sperm collection factorial pattern. The results showed no difference in odor, color, consistency on both types of cock and sperm at different the morning collection and the afternoon collection. Types of chickens were Ketawa chicken and Pelung chicken had significant effect (P�0,05) with volume at 0,172±0,107 ml, had 7,500±0,853 and 6,960±0,929 pH and consentration in 1,858±1,658.109/ml and 2,803±1,517.109/ml. Types of chicken and time of sperm collection had significant (P<0.05) with motility of spermatozoa in 78,833±15,574% and 62±25,834%. Time of collection had significant effect to viability of spermatozoa in 58,957±13,489% and 48,059±7,722%. In the volume, pH, sperm viability and concentration there were no interaction between type of chicken and time of collection, but it had in sperm of motility. From these results it could be concluded that the Pelung chicken had quantity and quality of sperm were better than Ketawa chicken , while for the quantity and quality of the sperm with afternoon collecting better than the morning, there were no interaction between types of chicken and time of sperm collection.
