Background and Aim: Coat color is a phenotypic trait that is affected by many functional genes. In addition, coat color is an important characteristic of breeds in livestock. This study aimed to determine functional genes for coat color patterns in Sumatran native cattle in Indonesia using a genome-wide association study method. Materials and Methods: A bovine single nucleotide polymorphism (SNP) 50K BeadChip was used for the investigation. A total of 46 Sumatran native cattle of three colors as follows: Brown (36 animals), white (9 animals), and black (1 animal), were used as experimental animals. Results: Results showed that the SNP markers ARS-BFGL-NGS-75486 (p = 2.46×10-7) and BTB-01992588 (p = 1.06×10-5) were selected as two genetic markers for coat color variation in animals under study, which were located at the cytoplasmic FMR1-interacting protein 2 (CYFIP2) gene at BTA7 and small G protein signaling modulator 1(SGSM1) genes at BTA17, respectively. The polymorphic informative content values of both SNP markers were 0.33 (ARS-BFGL-NGS-75486) and 0.13 (BTB-01992588). In this study, a genetic marker for coat color patterns in Sumatran native cattle was obtained based on the haplotypes of both SNP markers. Conclusion: It can be concluded that CYFIP2 and SGSM1 are two coloration genes that affect the phenotype characteristics of Sumatran native cattle.

Abstract Calcium (Ca) is an essential mineral for eggshell formation and muscle contraction, and a lack of it can result in poor egg quality and decreased egg output in laying ducks. This study aims to see how feeding the mineral Ca in a ration containing Shrimp head meal and Bilis fish head affects the laying performance and quality of hatching eggs in Mojosari ducks. A total of 105 female and 15 male Mojosari ducks, aged 78 weeks, were raised for three months and randomly divided into 15 flocks (each flock containing seven females and one male duck). There were three kinds of treatment, namely P0 (control, without mineral), P1 (ratio of Shrimp head meal and Bilis fish head 2:1 + 1% mineral), and P2 ((ratio of Shrimp head meal and Bilis fish head 1:2 + 1% mineral). The findings revealed that adding mineral Ca to feed, including Shrimp head meal and Bilis fish head, had no significant influence (P>0.05) on laying Mojosari duck performance in terms of feed intake, egg production, egg weight, egg quality, ducklings produced, and income over feed cost (IOFC). Furthermore, Ca addition in the ration did not result in substantial increases (P>0.05) in fertility, hatchability, or egg size characteristics. Based on the findings of this study, feeding ducks with shrimp head meal and Bilis fish head can be used as an alternate calcium-free feed formulation.

Abstract Assessment of the existence of macroalgae and revealing the chemical composition to investigate the potential usage for feed to support sustainable beef production has been conducted in Indonesian prominent livestock production area specifically Lombok, Bali, Yogyakarta, Lampung and Bengkulu. These regions host numerous seaweed production centres, while others hold the capacity to develop into seaweed cultivation zones. To assess the existence, utilisation, and accessibility of macroalgae in each region, observations and interviews were conducted. Subsequently, dominant macroalgae species were sampled and subjected to proximate analysis to determine their nutritional profiles. The results showed that the dominant macroalgae observed included red algae (Rhodophyta) like Eucheuma sp., Gracilaria sp., and Acanthophora sp., green algae (Chlorophyta) such as Ulva sp. and Caulerpa sp., and the brown alga (Phaeophyta) Sargassum sp. The dominant macroalgae found in all five observation sites with high abundance were Sargassum sp., Gracilaria sp., and Eucheuma cottonii. Ulva sp. and Eucheuma spinosum were present at four sites, while Acanthophora sp. and Caulerpa sp. were found at three sites. The dry matter content of the macroalgae ranged from 9.92% to 17.01%, with the highest values observed in the Eucheuma group (14.11%-17.01%). This was followed by Sargassum sp. (12.55 ± 2.40%), Ulva sp. (12.28 ± 2.33%), and Gracilaria sp. (11.09 ± 3.79%). Caulerpa sp. exhibited the lowest dry matter content (9.92 ± 1.29%). The crude protein (CP) content varied both within and between groups of algae species and observation sites. Gracilaria sp. exhibited the highest CP content (13.55 ± 0.16%), followed by Caulerpa sp. (11.87 ± 2.22%), Sargassum sp. (8.98 ± 0.42%), and Ulva sp. (6.98 ± 0.94%). The mineral content of the macroalgae was noticeably high, which is reflected in the low organic matter content. Ulva sp. had the highest organic matter content (80.17%), followed by Sargassum sp. (70.55%), Gracilaria sp. (66.53%), Caulerpa sp. (47.61%), and Eucheuma cottonii (43.50%). The readily available seaweed in this study tend to exhibit moderate to high protein and mineral content, making it a promising partial replacement or supplement for conventional feed, potentially contributing to sustainable beef production. Gracilaria sp., the most readily available seaweed, high in nutrient content with the potential to partially replace conventional feed protein sources. Its abundance of vitamins and minerals may enrich the overall value of the feed.

Beef cattle cultivation is a side job for farmers which is carried out by family labor and the incomes are used to finance various needs of the farmers’ family. This study aims to determine the use of family labor in beef cattle cultivation and the use of livestock sales. The research was carried out from October 2020 to April 2021 in two Women Farmers Groups (WFG) in Bengkulu City and Seluma Regency who received beef cattle assistance from the government. Data were analyzed descriptively. The results showed that in general, beef cattle cultivation was carried out jointly by man and women farmers with a labor allocation of 39.59%. In intensive farming, farmers are more dominant in cultivation activities amounting to 46.25%, while in semi-intensive farming women farmers are more dominant in cultivation activities (41.06%). The income from the sale of livestock are mainly used for children's education expenses and buying vehicles (91.67% each), building or renovating houses (87.50%), and buying feeder cattle (79.17%). For the development of beef cattle in farmer group, it is necessary to consider the cultivation system before determining the target of recipient of the program. The development by WFG is more suitable for semi-intensive cultivation systems.

The objectives of this study was to determine soil fertility and types of plants in understorey ecosystems in oil palm plantation stand which are managed in different ways. The data collection method was a direct observation on smallholder oil palm plantation at 15 years of age with different management, namely: 1) weed control using herbicides, 2) without management, and 3) used for beef cattle grazing. The data consisted of soil fertility and identification of understorey species in each management. The soil samples were taken in a composite manner and analyzed in the laboratory, while the plant species samples were gathered using the 1x1 m2 method and identified using an identification manual. From the results, weed control in oil palm plantation with cattle grazing has a positive impact on soil fertility compared to the use of herbicides and without control. The diversity of understorey species in cattle grazing locations is less, namely, as much as 11 species compared to the use of herbicides (15 species) and without control (22 species). Weed management by grazing cows in the oil palm plantation increased land fertility and the dominance of understorey plants as a source of animal feed.

Abstract Upland rice is a useful source of germplasm and it is conserved by farmers through local wisdom. This paper aims to explain fading the local wisdom of upland rice in situ conservation in Pino Raya subdistrict, South Bengkulu regency. Data were collected from March to May 2020 through interviews and field observations. The interviews involved 11 key informants using snowball techniques consisting of a customary leader, village heads, agricultural extension, and farmers. Data were analyzed descriptively using the interactive model from Miles and Huberman. The results showed that the local wisdom of in-situ conservation of upland rice faded because shifting cultivation was no longer practiced by farmers due to oil palm expansion. Cultivation of upland rice is only on young oil palm plantations that are increasingly entering forest area. Intensification of wet rice cultivation allows farmers to cultivate modern varieties which early maturing rice and high productivity. Improvement in the community’s economy due to oil palm expansion and the diminishing of the upland area for rice cultivation caused the young generation to no longer be interested in planting upland rice local varieties. As a result, the “Dundang Padi” ceremony as a form of local wisdom that is practiced by the Pino Raya community is fading.
