Risk aversion, grassland used for non-animal-husbandry purpose and herdsmen's grassland transfer behavior

ABSTRAKAir kelapa muda varietas viridisdapat dijadikan pengencer aletrnatif semen cair bagi program IB di daerah minim sarana semen beku. Tujuan penelitian ini untuk menguji pengaruh penggunaan air kelapa muda viridissebagai bahan pengencer terhadap kualitas semen cair kambing Boer setelah didinginkan. Dilaksanakanselama 3 bulan di Laboratorium Fakultas Peternakan UBUnit SumberSekar,Malang. Metodenya yaitu eksperimen. Semen dari 3 pejantan Boer umur 3-5 tahun, dikoleksi seminggu sekali dengan VB. Air kelapa mudaviridis umur 5-7 bulan serta tris aminomethane sebagai kontrol. Didesain menggunakan Rancangan Acak Kelompok (RAK) dengan 2 perlakuan yaitu P0 (tris aminomethane + 10% KT) dan P1 (air kelapa muda viridis + 10% KT) masing-masing diulang 10 kali. Data dianalisis dengan analisis Ragam (Anova) dengan software Genstat 18. Variabelnya yaitu motilitas individu, viabilitas dan abnormalitas. Hasil penelitian yaitu motilitas individu pada P1bertahan sampai 4 hari (40,5± 24,3%), viabilitas terbaik sampai hari ke-5 (42±24,6%), abnormalitas terendah di hari ke-7(1,31± 0,6). Kesimpulannya, Pengencer air kelapa muda viridis dapat mempertahankan kualitas semen cair kambing Boer selama 4 hari untuk motilitas dan 5 hari untuk viabilitas.Kata Kunci:pengencer, air kelapa, varietas viridisABSTRACTYoung viridis coconut water could be used as an alternative to liquid semen diluent for artificial insemination program in the area with limited facility for frozen semen production. This study evaluated the use of young coconut water as a diluent on liquid semen quality of Boer goat after cold storage. This study was carried out for 3 months at Sumber Sekar Laboratory, Faculty of Animal Husbandry, University of Brawijaya, Malang. The semen was collected from 3 Boer bucks aged at 3 to 5 years old. The semen collection was done once a week with the aid of artificial vagina. The diluents used were young Viridis coconut (5 to 7 months old) and tris aminomethane. The method used was an experiment in a randomized block design with 2 treatments and 10 replicates. The treatments used were T0: tris aminomethane + 10% egg yolk (control) and T1: young Viridis coconut water + 10% egg yolk. Data were analyzed by analysis of variance using Genstat 18 software. The variables measured were sperm individual motility, viability, and abnormality. The results showed that the sperm individual motility in T1 survived up to 4 days (40.5± 24.3%), the best viability at 5 days (42.0±24.6%), while the lowest abnormality at 7 days (1.31±0.6). It could be concluded that: 1. Tris aminomethane diluent has higher quality with the storage length up to 9 days, 2. Young Viridis coconut water diluent could preserve liquid semen quality of Boer goat up to 4 days for sperm motility and 5 days for sperm viability.Keywords: diluents, coconut water, viridis variety

Aquaculture Production

Aquaculture production is a promising direction for the development of food production. Like traditional types of animal husbandry, it needs effective medicines for veterinary use, which would ensure not only the well-being of farmed aquatic organisms, but also increase the safety of the fish products and non-fish objects of fishing. The development of measures to control epizootic processes in aquatic organisms is impossible without the creation of new immunological preparations. The development and use of immunobiological drugs will reduce the use of antimicrobial agents. The corresponding set of pharmaceutical drugs was transferred from the traditional veterinary medicine, but due to the peculiarities of the biology of aquatic animals, their immunity and the characteristics of specific pathogens, this could not be done with biological products. The short development time in the aquaculture industry poses current challenges in the form of a lack of basic and applied research for relatively poorly understood groups of new pathogens. The immunological processes associated with the development and intensity of the immune response in aquatic organisms require a detailed study. For domestic aquaculture producers, the analysis and dissemination of the experience accumulated by mankind and the application of advanced developments in this area are even more relevant, since Russia is just beginning its path of intensifying aquaculture production. At the same time, it is clear that the prohibition of the use and monitoring of antimicrobial agents in food products and feed requires a change in the approach to the problem and will lead to the creation of new immunobiological drugs. The market for immunobiological preparations for aquaculture is the most promising for development. In the article, the authors provide data on the development and registration of vaccines for aquaculture in Europe, North and South America.
