This research aims to determine the performance of the grower phase until the first egg laying of mojosari ducks given turmeric flour supplementation. This research used 40 mojosari ducks aged 16-28 weeks. The experimental research method used a completely randomized design with five treatments and four replications. The study was carried out for 12 weeks, maintained intensively, and given basal feed with the addition of 0.2%, 0.4%, 0.6%, and 0.8% turmeric flour. Basal feed is made from fine bran, ground corn, and concentrate. The parameters observed were the final weight of the growth phase, body weight gain, feed conversion in the growth phase, body weight and age at first egg laying, and the weight of the first egg. The data obtained was then analyzed using analysis of variance (ANOVA) and Pearson correlation. The results showed that adding turmeric flour at 16-24 weeks of age was able to increase body weight gain and reduce feed conversion rate (p<0.05), and at 24-28 weeks of age could accelerate the age of first egg laying (p<0.01). Pearson correlation showed that there was a positive relationship (0.462) between age at first laying and first egg weight, a negative relationship (-0.569) between age at first laying and body weight, and a negative relationship (-0.398) between duck body weight and first egg weight. Adding 0.6% turmeric flour to feed is the optimal and best level to improve the performance of mojosari ducks from the growth phase to the egg-laying phase.

One type of livestock business in several of Indonesia's rural areas is the profit-sharing beef cattle farming system, where investors and livestock keepers share the profits. This profit-sharing scheme is known as the teseng system in South Sulawesi Province. This study aims to determine whether the availability of capital, land area, business scale, age, income, and the number of family dependents affect beef cattle farmers' utilization of the teseng profit-sharing system in Temmabarang Village, Penrang District, Wajo Regency, South Sulawesi Province of Indonesia. The type of research used was a descriptive and explanatory research method. Technique sampling was done by simple random sampling with 90 respondents. The data was obtained and analyzed using a well-structured questionnaire and a binary logistic regression model. The results showed that the factors that significantly affected farmers' participation in the teseng system were the availability of capital, business scale, age, and income. In contrast, the factors that had no effect were the variable perceptions of land area and the number of family dependents.

ABSTRACT

Native Indonesian beef cattle have existed in Indonesia for a long time. Local beef cattle originate from outside Indonesia but have been bred and cultivated for a long time in Indonesia, so they have specific characteristics. Balinese cattle (Bos sondaicus) are beef cattle native to Indonesia, while local cattle are Madurese cattle and Sumba Ongole (PO) cattle. This study aimed to determine the population structure of beef cattle and the population dynamics of beef cattle based on the percentage of births, deaths, and the slaughter of productive females. This research was conducted in March - April 2023. This research was conducted in Bulo Timoreng Village, Panca Rijang District, Sidenreng Rappang Regency, with a sample of 53 respondents. The researchers used a survey method through observation and interviews. The data analysis used in this research is a descriptive statistical analysis that calculates the percentage of population data and population dynamics data. The population structure based on age is adult 60.47% (male 21.34% and female 39.13%, heifer 28.26% (male 15.47% and female 12.79%), and calf 11.27% (male 5.72% and 5.55% for females. Population dynamics based on the birth rate for the past year is 11.27%, the mortality rate is 3.62% (2.41% for males and 1.21% for females), while the slaughter rate productive females as many as 11 heads with a percentage of 1.65%.

Forage must be available sustainably in both quality and quantity to support ruminant farming, so it requires soil that contains sufficient nutrients. This study aims to determine the growth, production, and quality of Pakchong elephant grass after being given liquid organic fertilizer in different doses. The experiment conducted in this study used a completely randomized design (CRD) with five treatments and five replications, namely P0 (No liquid organic fertilizer), P1 (Liquid organic fertilizer 40 liters/ha equivalent to 29 ml/plot), P2 (Liquid organic fertilizer 50 liters/ha equivalent to 36 ml/plot), P3 (Liquid organic fertilizer 60 liters/ha equivalent to 43 ml/plot), P4 (Liquid organic fertilizer 70 liters/ha equivalent to 50 ml/plot). The results showed that implementing various levels of liquid organic fertilizer positively impacted the growth of Pakchong elephant grass. In the parameters of plant growth, the best results were obtained in the P4 (70 l/ha) and P3 (60 l/ha) treatments compared to P0 (without fertilizer). Production of Pakchong elephant grass using liquid organic fertilizer in different doses obtained the best results on treatments P4 and P3. The provision of different doses did not significantly affect (p>0.01)the nutritional content of Pakchong grass.
