Mendahara Ilir area is one of the areas in East Tanjung Jabung which has a high enough potential for shrimp, one of which has high economic value is Jerbung Shrimp. It is feared that the increasing activity of catching Jerbung shrimp will lead to overfishing. One of the important things in catching fish is paying attention to the size structure of the caught shrimp. The size of shrimp suitable for capture is a reference in the management of capture fisheries for the sustainability of shrimp resources in the future. This study aims to determine the structure and size suitable for catching Jerbung shrimp using Sondong fishing gear in Mendahara Ilir waters. This study used the Simple Random Sampling method, that is, the number of samples taken was 10% of the total catch of Jerbung prawns. The results showed that Jerbung prawns caught using Sondong fishing gear were in the range of 100-156 mm. The coefficient value of the correlation between length and weight of Jerbung prawns is 2.3 which indicates that the growth pattern of Jerbung prawns is negative allometric. The percentage of suitable size for catching is 78% and not suitable for catching is 22%. The conclusion of this study is that the percentage of Jerbung shrimp size suitable for catching is greater than not suitable for catching but in this study it has not been included in the good criteria.
Twenty cattle were used in this experiment to determine the effect of administration follicle stimulating hormone (FSH) and pregnant mare serum gonadotrophin (PMSG) hormones on superovulation of Brahman cross cattle. The experiment was designed into completely randomized design with 5 treatments as follows. Treatments 1 (T1): 4 mg of FSH was injected twice a day intra-ovary, T2: 8 mg of FSH was injected twice a day intra-ovary, T3: 300 IU of PMSG was injected single dose intra-ovary, T4: 600 IU of PMSG was injected single dose intra-ovary, T5: 40 mg of FSH was injected intramuscular. All experimental cattle were oestrus synchronized using 15 mg of PGF2α twice at 11-days intervals. Number of corpus luteum (CL) was detected by rectal palpation at day-7 after artificial insemination. Results showed that 19 cattle (95%) indicated oestrus sign. Eleven cattle (57.9%) showed oestrus sign 2 days after PGF2α injection and the rest 8 cattle (42.1%) oestrus sign was detected at 3 days after PGF2α injection. FSH and PMSG treatments increased significantly (P Key words: Brahman cross, corpus luteum, PMSG, FSH
The objective of this study was to observe the effects of super ovulation treatments on the number of ovulated corpus luteum. Metode yang digunakan dalam penelitian adalah metode eksperimen. The method used in this study was experimental. Sapi-sapi diprogram untuk sinkronisasi estrus menggunakan PGF2ά. The cows were programmed to experience estrous at relatively the same time (estrous synchronization) using PGF2ά. Sapi-sapi tersebut kemudian dibagi secara acak menjadi empat perlakuan, masing-masing terdiri dari empat ekor sebagai ulangan. Data yang dihimpun dalam penelitian ini adalah jumlah corpus luteum, dan jumlah folikel tetap. Cows were divided randomly into four treatments, each of which consisting of four heads. The number of corpus luteum and the settled follicles was collected during the study. Data dianalisis menggunakan Rancangan Bujur Sangkar Latin, jika perlakuan berpengaruh nyata maka dilajutkan dengan uji lanjut Duncan. Data were analyzed using a Latin Square design. In case there was a significant difference, Duncan test was used thereafter. Result showed that Hasil penelitian menunjukkan bahwa penggunaan PGF2ά dalam pelaksanaan sinkronisasi estrus berjalan cukup baik.Hasil penelitian ini menunjukkan bahwa perlakuan superovulasi berpangaruh nyata terhadap Corpus Luteum dan folikel menetap.super ovulation had a significant effect on corpus luteum and settled follicles. Kesimpulan penelitian ini protokol terbaik superovulasi tahun pertama adalah T-3 karena menghasilkan Corpus luteum dan Embrio yang lebih banyak.In conclusion, the best super ovulation protocol in the first year was the combination of 4 day daily injection of 40 mg of FSH in decreasing dose plus 250 µg of GnRH given at the time of estrous, because it was able to yield greater number of corpus luteum and embryos.

Abstract
This study aimed to determine the quantitative characteristics, the determinant of body size and shape, and the correlation of body measurements and the bodyweight of Bali and Simbal cattle in Renah Pamenang, Merangin District. The survey method was used along with purposive sampling, the samples were Bali and Simbal cattle aged I1 (Incicivus 1) and not in pregnant condition, with 60 cattle consisting of 30 males and 30 females. Observed data included: body weight, body weight gain, body length, shoulder height, chest circumference, chest weight, chest width, hip height, and canon circumference were analyzed using the t-test method. The principal component analysis was used to determine the determinant of size and shape of Bali and Simbal cattle followed by the regression and correlation analysis to determine the relationship and closeness of the relationship between body measurements with body weight. The result showed that the body weight, body weight gain, and body size of Bali cattle were significantly different (P <0.05) from Simbal. The body weight, body weight gain, and body size of Bali cattle were lower than Simbal cattle. The main characteristic of size in Bali and Simbal cattle was the Chest Circumference. The dominant characteristic of shape in Bali and Simbal cattle was shoulder height. The highest correlation between body measurements and body weight in Bali and Simbal cattle was the chest circumference.

The Kerinci duck (Anas platyrhynchos), hailing from Jambi Province, represents one of the local duck breeds of Indonesia. This study aimed to ascertain the matrilineal origin of Kerinci ducks through analysis of the mitochondrial NADH Dehydrogenase subunit 2 (MT-ND2) gene. In this pursuit, forward sequences of the MT-ND2 gene (490 bp) were extracted from unsexed Kerinci ducks, totalling forty-eight (48) sequences, procured from blood samples. The findings demonstrated the identification of fifteen (15) distinct haplotypes within the MT-ND2 gene, with corresponding haplotype diversity (Hd) and nucleotide diversity (pi) values of 0.74 and 0.003, respectively. The resulting phylogenetic tree unveiled that Kerinci ducks exhibit two matrilineal origins: an Asian and an independent Kerinci lineage. Moreover, most Kerinci ducks were categorised within the H4 group (24 birds) of the Asian lineage. Nevertheless, this study also revealed the existence of an independent Kerinci lineage comprising eight (8) duck haplotypes. In conclusion, the analysis of the MT-ND2 gene underscored the genetic introgression of A. zonorhyncha and A. poecilorhyncha in Kerinci ducks.
