Abstract

Superovulation treatment on PO cattle (Bos indicus) was less responsive compared to Bos taurus breed. It might due to the difference of their follicular dynamic. This study was conducted to investigate the follicular dynamics and its repeatability in PO cattle. Follicular dynamics observations conducted on 9 cows trough ultrasound scanning every day. Observations of wave patterns repeatability were performed in 6 cows which its wave pattern already known on the next consecutive IOI.  Research result indicated that PO cattle had 3 (66%) and 4-waves (34%) pattern. The first wave of 3 and 4-waves pattern emerged on day -0.4+0.9 and 1.4+1.1 respectively.  The second wave of 3 and 4-wave pattern emerged on day 9.8+1.5 and 7.4+1.9 respectively.  The pattern of 3 waves has a longer follicle dominant duration (11.6+1.5 day) in the first wave of estrous cycle, compared with 4 waves pattern (10+2.92 and 7+1.00 day respectively). The growth rate of dominant follicle was not different significantly between the 3 and 4-waves pattern (0.87+0.23 and 0.94+0.25 mm/day respectively). Similarly, ovulatory follicle diameter between 3 and 4-waves pattern was also not different significantly (12.24+12.34 and 12.30+12.23 mm respectively). Observation of wave patterns repeatability in 6 PO cows indicated that PO cattle had high repeatability in follicular wave pattern (0.88) and the number of growing follicle was 0.91.  This study resulted data for dynamic of follicular development, wave pattern, its repeatability which be expected to design the protocol of superovulation treatment or other reproduction technologies based on follicular dynamic to improve its result in PO cattle.

Abstract

PO cattle have weaknesses to show clear estrus signs which cause difficulty in artificial insemination implementation. The present study was designed to obtain ovarian dynamic as effect of GnRH injection in ovsynch protocol based on progesterone intravaginal device. Heifers (18) and cows (n= 12) were allocated to one of three groups. Cuemate-PGF2α (CP) group inserted with a Cuemate on day 0-7 and injected with prostaglandin on day 7. Cuemate-PGF2α-GnRH (CPG) group was treated as CP group with the addition of GnRH injection on day 9. GnRH-Cuemate-PGF2α-GnRH (GCPG) group was treated as CPG group with addition of GnRH injection on day 0. Ultrasonography was performed on days 0-3, day 7 until ovulation and 7 days after ovulation. Percentage of ovulation synchronization increased significantly (P<0.01) between CP, CPG, and GCPG, respectively, both in heifers (16%, 50%, and 85%, respectively) and cows (0%, 60%, and 100%, respectively), on day 11. Preovulatory follicle diameters between CP, CPG, and GCPG treatments were not different significantly both in heifers (11.9±0.5, 11.9±0.5, and 12.1±0.6 mm, respectively) and cows (11.7±0.4, 11.8±0.7, and 11.1±0.6 mm, respectively). This study concluded that GCPG protocol increased the synchrony of ovulation rate both in cows and heifers, without affecting the follicle preovulatory and CL diameters.

Abstract

Pepper yellow leaf curl disease caused by Begomovirus is a very important disease in chili plantation. The use of pesticides to control this disease has not yielded satisfactory results, so this study aimed to use arbuscular mycorrhiza fungus (AMF), to control curly leaf yellow disease of chili peppers. Pepper seeds were inoculated with AMF, i.e., T0 = seeds without AMF inoculation, T1 = seedlings inoculated with AMF at nursery, T2 = seedlings inoculated with AMF at transplanting, and T3 = seedlings inoculated with AMF at nursery and transplanting. Parameters observed every week were disease intensity and infection rate of yellow leaf curl disease. Results indicated that inoculation of AMF could delay Begomovirus infections and symptoms emergence of pepper yellow leaf curl disease. INTISARIPenyakit daun keriting kuning cabai disebabkan Begomovirus merupakan salah satu penyakit penting pada pertanaman cabai. Upaya pengendalian dengan menggunakan pestisida belum memberikan hasil yang memuaskan, sehingga penelitian ini bertujuan untuk memanfaatkan Jamur Mikoriza Arbuskular (JMA) dalam mengendalikan penyakit daun keriting kuning pada cabai. Penelitian dilaksanakan dengan menginokulasi bibit cabai menggunakan JMA dengan perlakuan T0= bibit tanpa inokulasi JMA, T1= bibit diinokulasi pada saat pembibitan, T2= bibit diinokulasi pada saat pindah tanam ke lahan pertanaman cabai, dan T3= bibit diinokulasi pada saat pembibitan dan pada saat pindah tanam ke lahan pertanaman cabai. Pengamatan dilakukan setiap satu minggu sekali dengan parameter pengamatan meliputi intensitas penyakit dan laju infeksi penyakit daun keriting kuning.

Abstract

Fishing vessel is one of the units in fishery activities with high operational risk that can cause accidents, both ship and crew accidents. Most of the fishing vessels that operate in Indonesia were made traditionally without any planning. Fishing vessels in Pekalongan Fishing Port still built using traditional methods. Shipbuilding planning requires rules to produce ship construction that meets the standards. The rules that used as a reference is ship classification and ship construction from Biro Klasifikasi Indonesia (BKI). BKI was established by implementing technical standards in the activities of design and construction as well as maritime surveys related to floating facilities, including vessels and offshore construction. This study aims to obtain the cross-sectional dimension of some parts of the fishing vessel construction and to analyze the dimension appropriateness of Purse Seine in Pekalongan Fishing Port with BKI standard. This study was used purposive sampling and the data were collected using interview, observation, measurement, and literature study. The data were analyzed using numerically-comparative method. Some parts of fishing vessel constructions measured in this study consisted of keel; high bow; ivory; machine foundation; outer skin; and fences. Research showed that there are 53,18% of construction sizes that meets the criteria of BKI, while there are 46,83% of construction sizes does not meet the criteria of BKI.

Abstract

The beef cattle industry in Indonesia hampered by low population and productivity. Apart from genuine adaptability to tropical condition and low input of production, local breeds basically have small body size and low daily weight gain. During the last few years, through artificial insemination (AI) program the government has introduced crossbred of various European breeds with local cattle. Moreover, embryo transfer (ET) program, has also been adopted to support the foundation of elite cattle.    Balai Embrio Ternak (BET) Cipelang, a centre to produce and distribute embryos of high genetic quality cattle is responsible to develop a modern breeding program through embryo technology. The center, since its establishment in 2000, has produced and distributed thousands of bovine embryos of local and exotic breeds [1].  BET Cipelang has mandated to implement a large-scale importation of Belgian Blue (BB) embryos. Nine hundred frozen BB embryos have been imported from Belgium and transferred to recipients at various breeding centres. To study the performance of  the crossbred between local breeds and BB, 1000 frozen semen of BB bulls were imported and inseminated [2}.   The BB cattle has widely known as the breed with double muscling properties. The significance of this project is to study the BB capability on coping up with various local constraints to produce Indonesian BB. The breeding program of the local breed with BB through AI will direct the breeding policy on crossbreeding program. This study was developed to evaluate the success rate of AI and ET, calving ease, calves body weight, daily gains and some other phenotypic performance.

Abstract

In vitro fertilization technology in cows is an effort done to utilize ovary waste from cows slughtered in abbatoir. This study was aimed at assessing the qualiy of embryos resulted from in vitro fertilization by using frozen semen thawed in different temperatures. In order to get qualty semen, standardized thawing method is required. It was expected from this study that an optimum thawing temperature for frozen semen was determined to obtain quality transferable embryos. Three treatments consisting of thawing with water 37°C for 30 second (T1), thawing with water 25°C for 30 second (T2), and thawing with water 10°C for 30 second (T3). Data were subjected to an an anlysis of variance (Anova) and a Duncan test. Results showed that oocytes fertilized with frozen semen thawed at 37°C and 10°C had higher fertilization rate and excellent-grade embryos (P<0.05) than did the ones fertilized with frozen semen thawed at 25°C. However, no different effect of thawing temperatures was found on transferable and degenerated embryos (P>0.05). It was concluded that embryos fertilized with Brahman frozen semen in thawed at 37°C had the highest number of embryos (49.66±2.88) and excellent-grade embryos (22.00±4.35). Key words: Embryo quality, In vitro fertilization, frozen semen thawing, Brahman bull.
