The Willingness to Adopt Local Feed Innovation Among Cattle Farmers

2024-04-03T14:42:36+00:00

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.

2024-03-31T05:45:11+00:00

This study aims to determine the effect of sugar dosage and fermentation time on the quality of sauerkraut as a source of probiotics. This study used an experimental method in a 3x3 factorial completely randomized design (CRD). The first factor is three treatments of sugar concentration (A), namely A1 (2%), A2 (3.5%), and A3 (5%). The second factor is three treatments of fermentation time (B), namely B1 (5 days), B2 (7 days), and B3 (9 days). The results showed that there was no interaction (P>0.05) between factor A and factor B in the water content, but the water content had a significant effect (P<0.05) separately in factor A and factor B. In total LAB, there was a very significant interaction (P<0.01) between factor A and factor B, and in factor A and factor B. In pH, there was a significant interaction (P<0.05) between factor A and factor B, but a very significant effect (P<0.01) in factor A and factor B. In acid content there was a significant interaction (P<0.05) between factor A and Factor B, but a very significant effect (P<0.01) on factor A and factor B. This study concludes that cabbage processed into sauerkraut can be used as a probiotic supplement. The addition of 3.5% sugar and 7-day fermentation resulted in 91.11% water content, 3.43 pH, 2.93% total acid, and 7.4 x 10⁹total LAB

The research aim to determine Curcuma xanthorrhiza Roxb encapsulated as a feed additive and its implementation on broiler production performance. The method used was a field experiment using a Completely Randomized Design (CRD), which consisted of 6 treatments and 4 replicates, namely; (P0-) negative control (commercial feed), (P1+) positive control (antibiotic 0.1%), P2 (C. xanthorrhiza encapsulation 0.25%), P3 (C. xanthorrhiza encapsulation 0.50%), P4 (C. xanthorrhiza encapsulation 0.75%) and P5 (C. xanthorrhiza encapsulation 1%). The results showed that the addition of temulawak (Curcuma xanthorrhiza Roxb) encapsulation in broiler feed can have a very significant effect (P < 0.01) on IOFC, a significant effect (P < 0.05) on body weight, feed conversion, and gives no significant effect (P>0.05) on feed consumption and carcass percentage. The use of temulawak (Curcuma xanthorrhiza Roxb) encapsulation at the level of 0.50% in broiler feed, numerically showed positive results on feed consumption, body weight gain, carcass percentage, IOFC and feed conversion. In conclusion, the addition of temulawak (Curcuma xanthorrhiza Roxb) encapsulated at the level of 0.50% in broiler feed is recommended as a feed additive to replace antibiotics because it tends to increase broiler production performance

Performance Test to Select Female Tegal Ducks Based On Production Characteristics

2024-04-03T13:12:56+00:00

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

2024-04-01T06:09:43+00:00

The PPM1K (Protein Phosphatase, Mg2+/Mn2+ Dependent 1K) gene is assumed to associate with retail meat cuts. This study aims to determine the association of the PPM1K gene polymorphisms with retail meat cuts among various breeds of Indonesian sheep. The Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) approach was used to determine the polymorphisms of the PPM1K gene in 130 Indonesian rams aged 10-12 months with body weights ranging from 20-25 kg. The association study between PPM1K and retail meat cuts was analyzed using General Linear Model (GLM). The research showed that the PPM1K gene was polymorphic, with three genotypes: AA (458 bp), GG (259 bp and 199 bp), and AG (458 bp, 259 bp, and 199 bp). The PPM1K gene polymorphisms were significantly (P<0.05) associated with breast cut, which is the breast muscle and bone. The GG genotype of the PPM1K gene had a higher value on breast lamb. This result implies that the PPM1K gene could be a potential candidate for marker-assisted selection for improving the lamb quality of Indonesian sheep.
