Abstract

This study aimed to determine the genetic diversity among three duck populations (Bayang, Pegagan, and Pitalah) reared in Sumatera island, Indonesia, using microsatellite markers. Genetic diversity among populations (n = 90) was determined using 22 microsatellite markers, based on several indices: number of alleles (Na), observed heterozygosity (Ho), expected heterozygosity (He), polymorphism information content (PIC), and Wright’s F-statistics ( ). The total number of alleles detected across loci was 121. The Na per locus ranged from 2 (APH24, CAUD128, and CAUD009) to 18 (CAUD048 and CAUD040). The mean Ho (0.429) dan He (0.509) indicated that the level of genetic diversity among populations was moderate, while the mean PIC (0.46) suggested that the tested loci were informative for assessing genetic diversity. The mean F-statistics ( ) were 0.148, 0.198, and 0.060, respectively. The  value indicated that the level of genetic differentiation among populations was moderate. The results confirms a moderate genetic diversity among populations, which could be beneficial for designing conservation and utilization of the local ducks in Sumatera island.

Abstract

The study was conducted in 60 respondents of dairy farmers in Sleman Regency, Yogyakarta from August 2020 to February 2021. The study aims to make comparison between recording in the REKS-EL version 1.0 and those in dairy farms recording, in order to improve REKS-EL features. Data of the farmer characteristics and recording components were collected by interviewed. Identification of components the dairy farmers recording was carried out using a list of questions in a table. The list contains 43 components, which were arranged based on the recording guidelines as written in the Indonesian Minister of Agriculture No. 100, 2014. The result of comparison between dairy farmers recording and REKS-EL version 1.0 feature showed differences on recording content. Software REKS-EL has more recording components than dairy farmers recording, as much as 23 vs. 13 (46% vs. 23% of total components). The REKS-EL feature showed advantages on data of pedigree, and reproduction but needs to be improved with the additional components derived from farmer records, namely daily and weekly milk production. In the REKS-EL feature also needs to be added feed data, body condition score and calf after birth.

Abstract

In Indonesia, one of the sources of regional livestock genetic diversity is the kampung chicken. This study aimed to assess the development and reproductive potential of F1 Kampung Unggul Balitbangtan (KUB) crosses (KUB roosters with different types of combs crossed to layer chickens). This research was conducted at a private chicken company in Gunungkidul regency using 40 KUB roosters and 320 layer chicks. The KUB roosters were separated into four groups based on their comb types: single, walnut, and double. Each set of ten males was housed in a single cage, with a male-to-female ratio of one to eight (male and female). Observed reproductive variables included egg weight (EW), hatch weight (HW), fertility, hatchability, number of eggs, number of day-old chicks (DOCs), and number of saleable chicks. The body weight (BW) of the offspring at ages ranging from DOC, 4, 8, to 12 weeks of age is one measure of their growth characteristics. The analysis of variance using a one-way design and the DMRT test were performed to describe the difference in growth and reproductive performance across groups. As a result, each comb type revealed a significant difference in EW, HW, fertility, hatchability, egg and chick production, DOC, and saleable chick production (P<0.05). Compared to other combs, the single comb performed the best in terms of EW, HW, fertility, number of eggs, and number of DOC. The most hatchable and sellable chicks were from walnut comb. Therefore, comb size has a positive correlation with chicken reproduction and productivity. Comb type groups have no effect on BW at 12 weeks (P>0.05), while they significantly affect BW for DOC at 4 and 8 weeks (P<0.05). The rose comb shows BW at its maximum point. In conclusion, the rose comb has the biggest body weight and the single comb has the best reproductive performance in comparison to other comb types.

Abstract

This study aims to identify problems, identify and analyze stakeholders and determine indicators (qualitative and quantitative) for the sustainability of kalang buffalo production systems in swamp ecosystems in South Kalimantan. The kalang buffalo is a type of mud buffalo that is reared using the kalang system. In the local language, kalang is an enclosure built in the middle of swamp waters. This study is expected to be a source of information for academics, farmers, communities and policymakers in South Kalimantan Province regarding the strategic function of Kalang buffalo for the people of South Kalimantan. Data collection was done by describing the problem and determining relevant stakeholders. The literature study was conducted with expert discussion. FGDs were also conducted to explore important issues, followed by SWOT (Strengths, Weaknesses, Opportunities, and Threats) analysis and to determine relevant issues. Situation analysis and secondary data showed that the Kalang buffalo population is declining. Stakeholder identification identified the central and local governments as primary stakeholders; secondary stakeholders were scientists/academics, butchers, sellers, and consumers. The primary stakeholders selected were buffalo farmers, central and local governments, while secondary stakeholders consisted of scientists/academics, butchers, farmer sellers, and consumers. The selected indicators on the EES issue are economic indicators such as gross margin (GM), body weight, weaning weight, and reproduction (calf crop (%)); environmental indicators such as total grazing land use and waste disposal; and social indicators such total of buffalo, feeding procedures, mating system, cages, record keeping, time allocation for maintenance, social status and land use conflicts.
