The Pangandaran Regency in West Java has shown an increasing trend of beef cattle population over the past three years, reaching its peak of 18,938 in 2021, which indicates a potential opportunity for the development of beef cattle farming businesses. It is crucial to understand the key factors and strategies for this development. The study utilized a participatory survey method and the Harry King Nomogram technique to sample beef cattle farmers, collecting and analyzing the primary and secondary with descriptive, SWOT, and qualitative modeling analyses. The results showed that farmers in both lowland and highland areas were predominantly productive-aged. Performance metrics such as average service per conception and calving interval were observed at 14.48 and 2.37 in lowland areas, and 16.68 and 2.25 in highland areas, respectively. Key factors influencing the development of beef cattle farming in Pangandaran Regency included the availability of agricultural land, a supportive community environment, and effective breeding management. The SWOT analysis positioned both lowland and highland areas in quadrant I, suggesting that an aggressive growth-oriented strategy would be the most appropriate. Proposed strategies include increasing beef cattle population by optimizing agricultural land use, introducing technologies for processing forage feed and agricultural waste, aligning production with market demands through integrated farming practices, and implementing effective livestock waste management systems.

This study aimed to analyze the farmers' willingness in adopting local feed innovation and to analyze its background factors. This study involved 106 cattle farmers who lived in Arjowilangun and Kucur villages of Malang Regency, East Java. Data were collected from respondents through personal interviews with structured questionnaires. This study also used descriptive statistical analysis and Probit regression as the methods. The research results showed that most of the farmers were willing to partially adopt local feed innovation. Social and economic factors that statistically gave significant influence on the farmers' willingness in adopting the local feed innovation are age, the number of cattle, cattle agribusiness type, membership in a farmer's group, and the perception towards the cattle farming conditions. Age and the number of cattle negatively affect the farmers' willingness while membership in a farmer's group and perception towards the cattle farming conditions has a positive effect on the farmers' willingness in adopting local feed innovation. Farmers who are running the cattle fattening business have larger probabilities to reject the local feed innovation. Furthermore, optimizing coaching and assisting activities through the farmer's group can be an effective way to increase the farmers' willingness to entirely adopt the local feed innovations.

The labor production factor was an important production factor and needs to be taken into account in the production process. This study aims to find out how much the allocation of male and female labor in the family and analyze simultaneously the factors that influence the allocation of male and female labor resources in the family in the cattle business in West Kawangkoan District, Minahasa Regency. A survey method using interview techniques on cattle rancher household respondents, an econometric approach with a simultaneous equation model and SAS 9.4 software analyzed was used in study. The research showed male and female workers in the family in the cattle business are assessed as the supply or outpouring of male and female workers for the cattle business. In conclusion, the outpouring of male and female labor in the family was significantly influenced by labor wages, allocation of capital assistance, the number of cows reared, the number of cattle sold, and household income. Farm households will respond positively by allocating male labor in the family for the cattle business if there is an increase in the level of labor wages, capital assistance, and household income.

This study aims to determine the increase in production capacity through genetic quality improvement using selection techniques with the production capability test method in Tegal ducks. The research was conducted using an experimental method, using a nested pattern experimental design, male as treatment, female as sub-treatment, offspring as replicates, and production characteristics as observations. The selection population of Tegal ducks consisted of 10 males, 50 females, and their offspring. Production characteristics recorded included egg weight, hatching weight, and egg production. Egg production measured was Hen Day Production (HDP) at the initial laying period for 90 days. Assessment of genetic quality using individual breeding values (BV). Each individual's breeding value is calculated, and then the estimated breeding value (EBV) results are arranged based on their rank. Selection of parent candidates is done by maintaining 25, 50, and 75% of the total population. Selection results are obtained by estimating the selection response using different selection intensities. The results showed that the average and standard deviation of the characteristics of egg weight, hatching weight, and percentage of egg production in Tegal ducks were 67.76 ± 4.57 g, 40.40 ± 2.16 g, and 63.33 ± 10.89 %, respectively. Heritability values (h2) and standard error of egg weight characteristics, hatching weight, and percentage of egg production in Tegal ducks were 0.47 ± 0.032, 0.39 ± 0.0589, and 0.512 ± 0.071, respectively. The assessment for selection response was conducted based on three factors - egg weight, hatching weight, and percentage of egg production each week. The proportions were maintained at 25%, 50%, and 75%, respectively. The egg weight proportions were 0.46, 0.29, and 0.15, while the hatching weight proportions were 0.71, 0.45, and 0.23, respectively. The percentage of egg production each week was 47.92%, 30.18%, and 15.85%, respectively. The study’s results revealed that the intensity of selection and selection response of the Tegal duck were higher when smaller proportions were used in the selection process. It should be noted that the production characteristics used in the selection process were different, which resulted in varying heritability values and selection responses. Overall, these findings suggest that careful consideration of the selection factors is necessary to achieve optimal results in the selection process of the Tegal duck

The conclusion is that combination of BSA concentration significantly effect on proportion of X-Y chromosome bearing sperm, and concentration of 5% and 10% BSA at upper layer and bottom layer gave the higher proportion of X-Y chromosome bearing sperm of local ram sperm.

The current study aimed at generating essential information on breeding practices and traits of the economic importance of indigenous chicken (IC) farmers in the three historical regions of South Sudan (Bhar el Gazel, Upper Nile and Equatoria). Data on perceived important traits according to farmers (n=385), marketers (n=100) and consumers (n=100) were collected and analyzed through computation of indices which represented the average weight of all ranks of a specific trait. The results of the indices indicated that farmers selected body weight (3.16), disease tolerance (3.02), drought tolerance (2.70) and fast growth rate (2.44) for breeding cocks. For hens, high indices were observed on disease tolerance (2.95), hatchability (2.78), egg size (2.63), and egg number (2.48). Large Baladi (LB) and Naked Neck (Na) genotypes were the dominant genotypes raised by 64.8% and 27.7% of all farmers, respectively, for their superiority in mothering ability (40%), heat tolerance (20%) and disease tolerance (17%). Traits perceived by farmers as the primary economic importance were body weight (0.207), survival rate (0.11), egg yield (0.084) and meat quality (0.084). While marketers perceived body weight (0.234), egg yolk colour (0.150), disease tolerance (0.145), and plumage colour (0.133) as the most important traits, consumers emphasize egg yolk colour (0.202), plumage colour (0.204), and survival rate (0.156) as crucial. Body weight had a positive and favourable significant correlation with growth rate (0.561), egg fertility (0.412), disease tolerance (0.062), and a negative and unfavourable correlation with meat quality (-0.191). Meat quality was negatively correlated with fertility (-0.312) and growth rate (-0.381). Prolificacy had positive and favourable correlations with drought tolerance (0.603), disease tolerance (0.091) and heat tolerance (0.091). Regarding the preference rank correlation of marketers and consumers, positive and significant correlations were reported for body weight with growth rate (0.092) and meat quality (0.056). IC ecotypes that can perform well and are adaptable to the local environments in South Sudan should be identified. Selections should be based on traits preferred by farmers, marketers, and consumers.

Various lamb-based processed products have become popular in many countries, including Indonesia that are well known for lamb satay, lamb curry, grilled lamb, and others. Processing lamb meat into sausages is a potential alternative to diversify lamb-based processed food. This study aims to develop a lamb-based processed product in form of emulsion sausage. We used mixed lamb meat and fat of Batur lamb (0, 5, 10, 15, 20 and 25%) that was coarsely ground and added with 2.0% salt, 0.5% dextrose, 0.5% garlic powder, 0.5% pepper powder, 0.3% paprika powder and 0.5% chili powder. Meat, fat, and other ingredients are mixed evenly and then put into collagen casings and measured 10-cm long. Next, the sausage was steamed for +45 minutes, then cooled and drained. We used an experimental method with a Completely Randomized Design (CRD) assigning 6 treatments and 4 replicates. The treatments included T0: Lamb sausage without fat; T1 : Lamb sausage + 5% fat; T2 : Lamb sausage + 10% fat; T3 : Lamb sausage + 15% fat; T4 : Lamb sausage + 20% fat and T5 : Lamb sausage + 25% fat. The observed characteristics of sausages were chemical content (moisture, protein, fat, and ash content) and organoleptic properties (preferred colour, aroma, texture, taste, and acceptability). F test (anova) results showed that the treatment had a significant effect (P<0.05) on the moisture, protein, fat, and ash content of lamb sausage, as well as on preference for colour, aroma, texture, taste, and acceptance of lamb sausage. The results showed that the addition of 10% lamb fat produced emulsion-type lamb sausage with the most optimal characteristics, containing 63.290% water, 15.245% protein, 12.518% fat and 2.536% ash. The preferred colour, aroma, texture, taste and acceptance have satisfied the neutral criteria.

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.

Swine cattle have high economic advantages and social values ​​ in Balinese society. This study aimed to determine the effectiveness of Enterotoxigenic Escherichia coli (ETEC) vaccine in gestating sows. We used 26 gestating sows aged 1.5 years old at their last trimester assigning 13 sows in the control group and 13 sows in treatment group to receive multivalent ETEC vaccine twice: on the 70-75 days of gestation and a booster on 100-105 days of gestation. Sows with the vaccine treatment divided into 3 group that groups A was treated antifimbrial K41, groups B was antifimbrial 987P, while in group C was Antiimbrial K88. The changes in temperature were observed from one day before to 4 days after vaccination in a randomized block design. To determine the antibody formed, blood samples were taken one and two weeks after the first vaccine and five weeks after the booster. The blood sample was analyzed by the Enzyme Linked Immunosorbent Assay (ELISA) technique. The rates of diarrhea and postnatal mortality were also observed. The results showed that the antibody titer level increased significantly in the fifth week in groups A with titer 1,94 ±0,22 and B with titer 1,98 ± 0,30 , while the number of diarrhea incidents was 0.9% compared to control 34% with a mortality rate of 0%. In conclusion, this multivalent ETEC vaccine is safe to use and has been shown to be effective for ETEC cases in swine.
