  This study aimed to evaluate nutritional quality of total mixed rations containing Indigofera zollingeriana for dairy goats by using in vitro rumen fermentation technique (RUSITEC). Four rations with different levels of I. zollingeriana were tested, i.e., 20% of dry matter (R1), 40% (R2), 60% (R3) and 80% (R4). Each ration was repeated three times by following a randomized complete block design in which different batch of rumen fluid served as the block. Variables observed included chemical composition, In Vitro Dry Matter Digestibility (IVDMD) and In Vitro Organic Matter Digestibility (IVOMD), methane emission, Volatile Fatty Acid (VFA) profiles and protozoa population. Results revealed that R4 contained significantly higher crude protein content than that of R1-R3 (p<0.05). Rations containing higher proportions of I. zollingeriana (60 and 80% dry matter) had significantly higher IVDMD and IVOMD as compared to their lower proportions (20 and 40% dry matter, p<0.05). Methane concentration was lowest in ration containing the highest proportion of I. zollingeriana and it was accompanied with the lowest protozoa population. It can be concluded that higher inclusion levels of I. zollingeriana in rations improved their nutritional values while decreasing methane emission as a main greenhouse gas.

  One of the livestock products that play an important role in improving food security in Indonesia is beef. Increased income, changes in consumption patterns and population growth and increased public knowledge about nutrition affect the need for the number of cattle being slaughtered as one of the producers of meat protein in Indonesia. The purpose of this research was to determine the production capacity and consumption of beef in the province of East Nusa Tenggara (NTT). This research was conducted in NTT for 6 months, starting from Juli to Desember, 2019. This study of beef consumption is included in the case study classification. The type of data used in this study are primary and secondary data obtained from sources related to this study. Analysis of the data obtained was carried out descriptively, namely analysis carried out by way of explanation, writing and statements that could be in the form of words (qualitative) and numbers (quantitative). Data analysis was conducted to determine the production capacity of beef cattle, beef production and consumption of beef. The results of this study indicate that cutting cattle to meet the needs of the resident in NTT is increasing year by year along with the rate of resident growth and lifestyle of the community. The cuts carried out are still within the limits of Law which is under 10% of the total cattle population in NTT. But the slaughter of these livestock did not meet the standards of nutrition and animal protein needs. This is because the consumption of protein from beef products in NTT has only reached 12% of the ideal total protein requirement for each person.

  The aim of this study was to determine the productivity aspects (production and reproduction) of Bali cattle based on agroecosystems that include pasture, agriculture, plantation and forest on Timor Island. Therefore, from January-December 2018, research on the performance of Bali cattle production-based agroecosystem was conducted. The research location was chosen purposively representing agroecosystems of pasture, agriculture, plantation and forest. The number of respondents was 5-10% of the number of cattle farmers in each agroecosystem that had >10 Bali cattle. The respondents were interviewed using a questionnaire prepared. Field observations were also conducted to measure the performance of Bali cattle production. The data analysis used the Importance-Performance Analysis method which was processed through a computerized SPSS program and the results were explained descriptively. The results of this study indicated that the level of importance and performance of Bali cattle in the pasture, agriculture, plantation and forest agroecosystems showed the same conditions where the performance (productivity) of Bali cattle in each agroecosystem was good for such attributes as body weight, calf crop, and conception rate. Meanwhile, the attributes that need to be considered and improved are the quality and quantity of SKT, oestrus age, first coitus age, oestrus cycle, oestrus duration, service per conception, length of calf pregnancy, age of first calving, days open, calving interval and rate of increase population. Thus the productivity of Bali cattle scattered in pasture, agriculture, plantation and forest agro-ecosystems in general is still low.

  This research aims to project the development of Bali cattle population in the Timor Island pasture agroecosystem with a dynamic model for 75 years. The material used is Bali cattle (50 head of Bali cattle) with 12 months of research time from January-December 2018. Farmers and research locations were selected purposively based on criteria such as physical (land area), biology (agroecosystem) and social which generatessampling locations representing pasture located in the district of Belu, Malaka and Timor Tengah Utara. Respondents determination 5-10% of the number of farmers in theagroecosystem with the number of Bali cattle >10 cows (127 respondents). Respondents were interviewed using prepared questionnaire. In addition to interviews, field observations were also carried out. This research data uses primary data documentation. Data analysis uses a system dynamics approach with the help of powersim 2.5 software for windows. The results showed an increase in the population of Bali cattle will not reach it’s maximum point until the next 75 years if managed according to the existing conditions as applied, so far. Therefore, a strategy is needed to increase the population of Bali cattle by increasing livestock reproduction status and limiting the export/sale of Bali cattle in and out of the agroecosystem.

  The purpose of the research was to analyze the development of beef cattle population in Timor Island in supporting the role of Nusa Tenggara Timur as a beef cattle production area in fulfilling national meat needs. This research was conducted for 1 year, starting in January-December 2019 with the approach of agroecosystem location by purposive sampling based on physical criteria (land area), biology (availability and population of beef cattle) and socio-culture, so that, the sampling locations representing forest agroecosystems in Timor Tengah Selatan district. The material used was 136 beef cattle in the age range of 3-4 years involving 102 respondents beef cattle farmers. Respondents were interviewed using prepared questionnaires. In addition, field observations were carried out to determine the physiological status of beef cattle. This research uses primary and secondary data. Data analysis is done by building a dynamic system using Powersim and interpreting simulation results for the next 30 years. The results showed the role of Timor Island as an area of beef cattle production centers in supporting government policies to fulfill national meat needs to be considered in the aspect of beef cattle export from the province of Nusa Tenggara Timur because it would be problematic in aspects of beef cattle population on Timor Island. This is influenced by factors of calf mortality and brood stock mortality that are still high, low reproductive status of livestock and export of beef cattle that have not considered the ability of the region. Based on the results of dynamic system analysis shows that the government needs to reduce livestock quota according to the ability of agroecosystems to prevent the decrease in cattle population.
