The purpose of this study was to determine the growth patterns of female Kacang goats Growth Pattern of Different Body Dimensions in Female Kacang Goats. We measured 23 female goats for variables including body weight, chest circumference, shoulder height, and body length. The results showed that body weight followed the sigmoid curve pattern (S) with a regression equation y = 0.0005x3-0.0837x2 + 3.0707x + 0.119 with a coefficient of determination of 88.99%, while body size for chest circumference, body length, and shoulder height follows a polynomial pattern with regression equations y = -0.0627x2 + 3.1156x +40.333, y = - 0.033x2 + 1.6941x + 43.125, and y = -0.0418x2 + 2.1168x + 39.089, respectively and the coefficient of determination was 85.26%, 82.46%, and 68.53%, respectively. The research concluded that the growth of body dimensions in livestock has fluctuated. The increase of body dimensions in female-goat goats peaked at the age of 21-30 months, then started to decline during 31-40 months. It is correlated with the fact that age greatly affects the dimensions of the animal body. The highest coefficient determination value was observed in body weight, namely 88.89%.

This research was conducted to know the impact of methane reduction in ruminants using coconut pulp as feed substrate on the quality of goat meat. This study used coconut pulp as an antimetanogenic substrate and was added to ruminant feed. There were twenty goats aged + 1 year. The feed was given with a formulation of 60: 40% forage and concentrate in dry matter with a composition according to the needs of the goats. This research was carried out by treating coconut pulp with four levels of different treatment, namely 5, 10, 15, and 20% and compared with the treatment without using coconut pulp (0%). This experiment used a completely randomized design with four replications. The average difference of treatment was continued with the Duncan Multi Range Test (DMRT) test. The goats were kept for 60 days and they were slaughtered to measure the quality of meat. The variables measured were physical and chemical quality of goat meat. The results showed that the physical quality and the chemical quality of the meat had no significant effect. The conclusion of this research is the use of coconut pulp as an antimethanogenic substrate for goat feed can maintain the physical and chemical quality of meat and reduce meat cholesterol.

This study aimed to determine morphological, adaptability, and biomass production of Brassica rapa var. Marco planted in Karang Malang, Yogyakarta, Indonesia during the dry season. The seeds used were the introduced feed plants Brassica rapa var. Pillar from Crop Mark Seed Company New Zealand. The seeds were spread in 1 m2 plots. Each plant had 3 replicates at the end of rainy season (March) and defoliation in September. The variables observed in this study were plant growth and plant morphology. Also, biomass production, dry matter (DM), and organic matter (OM) content of each plant were statistically analyzed by independent sample t-test. Biomass production was taken from the first and second defoliation (first regrowth). The plant morphology showed that the plants could develop well. The plant growth showed that dry matter production of Brassica rapa var. Pillar was 1.15 tonnes/ha/year. The first and second defoliation of Brassica rapa var. Marco produced 1.61 tonnes/ha (DM 9.89% and OM 79.99) and 2.47 tones/ha (DM 9.17% and OM 84.82%), respectively, indicating significant difference. It can be concluded that the varieties of Brassica rapa var. Marco can thrive when planted during the dry season in Yogyakarta.

The purpose of this study was to evaluate the implementation of Qanuns (local regulations) for controlling productive cattle and buffalo in Aceh Besar District. This study conducted a census of abattoir officers to 10 respondents and 10 muge (intermediaries) to collect data on the population in this study involving all groups of cattle and buffalo farmers in Aceh Besar district, namely 627. The number of samples was determined based on the Slovin formula, i.e., 93 farmers with a 5% error rate. Also, a survey was conducted on six sub- districts in Aceh Regency based on a cluster sampling system. Data processing was done by calculating the percentage of measured parameters and presented in tabular form. The results of the study indicated that the implementation of Qanun decreased the slaughter of productive female cattle and buffalo in Aceh Besar District. However, public understanding of the control of productive female cows/buffalo Qanun remained low because only 30.98% of the public were aware of the Qanun. The lack of knowledge was indicated by the high slaughter and sales of productive female cattle and buffalo at the farmer level that only decreased by around 5.84% (from 70.88% to 65.04% after the implementation of Qanun. Economic needs were the reason for the high sales of productive female cows/buffaloes (73.13%). The weak implementation of Qanun on productive cattle and buffalo was probably due to poor socialization of Qanun for controlling productive cattle and buffaloes. 79.65% of the respondent group answered that they had never received socialization on controlling productive female cattle and buffalo. However, the contributing factors to the declining slaughter and sales of productive female cattle and buffalo since the introduction of Qanun were the strict regulations at the abattoir and the level of knowledge of the abattoir staff regarding Qanun to maintain productive cattle and buffaloes.
