Abstract

The study aimed to determine the carcass characteristics of local male pigs fed different energy sources. The research location is in Sasi Village, Kefamenanu District, North Central Timor Regency. The livestock used are 12 castrated local male pigs aged 12–16 weeks with a body weight range of 5–7 kg. The method used in the study is an experimental method using a completely randomised design (CRD) with 3 treatments and 4 replicates. The treatments tested were as follows: T1: 40% ground corn + 23% rice bran + 15% bran pollard + 22% fish meal; T2: 15% ground corn + 40% rice bran + 23% bran pollard + 22% fish meal; T3: ground corn 23% + rice bran 15% + pollard bran 40% + fish meal 22%. The variables observed in this study were slaughter weight, carcass weight, non-carcass weight, carcass percentage, and non-carcass percentage. The results showed that the treatments had no significant effect (P > 0.05) on slaughter weight, carcass weight, non-carcass weight, and carcass and non-carcass percentages of local male pigs in the growing phase. The slaughter weight for each treatment (T1, T2, and T3) was as follows: T1 was 6.867 kg, T2 was 7.936 kg, and T3 was 8.498 kg; the carcass weight for each treatment (T1, T2, and T3) was as follows: T1 was 3.466 kg, T2 at 4.115 kg, and T3 at 4.621 kg; the non-carcass weight for treatment T1 was 3.401 kg, T2 at 3.821 kg, and T3 at 3.886 kg; the carcass percentage for treatment T1 was 50.094%, T2 was 51.766%, and T3 was 52.674%; while the non-carcass percentages for treatments T1, T2, and T3 were 49.905%, 48.234%, and 47.325%, respectively.  It can be concluded that the use of ground corn, rice bran, or bran pollard as an energy source feed results in carcass and non-carcass production of local male pigs in the growing phase that are not significantly different, although there is a higher tendency when using 40% bran pollard in the diet.

Abstract

The purpose of this study was to assess the potential for ruminant livestock development in Lima Puluh Kota District by analyzing land cover and land use. A high-accuracy land cover map (kappa = 0.97) was created using Landsat 8-9 Path/Row 127/060 satellite imagery and the Random Forest (RF) classification method. Analysis was conducted using Geographic Information System (GIS) processes to evaluate land suitability. Slope, elevation, and proximity to water sources. As a result, about 35% of the district is highly suitable (S1) for ruminant farming. Due to the abundance of natural fodder and conditions conducive to extensive grazing systems, these ideal areas are mostly zones of dryland agriculture, mixed gardens and shrubs. However, due to limited fodder supply and geographical constraints, densely forested environments and urban environments are categorized as moderately suitable or unsuitable. The importance of improving livestock spatial arrangements was highlighted by the significant mismatches found when existing livestock population data were spatially overlaid with suitability maps. In conclusion, Lima Puluh Kota District has a strong biophysical basis to support ruminant livestock development. However, to ensure sustainable and effective use of land resources for livestock, spatial planning and land use policies must be aligned.

Abstract

This study aims to evaluate the effect of adding papaya leaf juice added to egg yolk citrate diluting medium (S-KT) to assess its effect on the quality of boar sperm from crosses between landrace and duroc breeds. Fresh semen from boar aged 1.5 who were in good health and had received training in semen collection methods was used in the study. Six treatments and five repetitions were employed in an experimental setting as part of a completely random research design, namely: egg yolk citrate without papaya leaf juice (P0), egg yolk citrate + 0.5% papaya leaf juice (P1), egg yolk citrate + 1% papaya leaf juice (P2), egg yolk citrate + 1.5% papaya leaf juice (P3), egg yolk citrate + 2% papaya leaf juice (P4),  egg yolk citrate + 2.5% papaya leaf juice. All treatments are stored in a coolbox with a temperature of 15-20ºC. Every twelve hours, the spermatozoa's mobility, survival, form, and ability to migrate were assessed. With a motility of 53.00±2.73%, viability of 67.70±1.4%, abnormality of 6.00±0.70%, and survival of 54.60 hours (P<0.05), the P5 treatment with the addition of papaya leaf juice up to 2.5% produced the best outcomes at 48 hours of storage. In comparison to previous treatments, it can be said that adding 2.5% papaya leaf juice to the S-KT dilution medium improved the quality of the liquid semen produced by Landrace and Duroc cross boar

Abstract

Antibiotic growth promoters (AGPs) are commonly used by the public to increase chicken growth, but they have health risks, namely causing resistance in humans and animals. Therefore, experts have begun to seek substitutes that focus on natural ingredients, such as yeast, as non-antibiotic alternatives. The most commonly used yeast probiotic is Saccharomyces cerevisiae (S._cerevisiae) var. Boulardi. One of the pathogenic microorganisms that attacks poultry is Campylobacter jejuni. This study aims to determine the effect of feed additives (S._cerevisiae), in broiler chickens on performance (weight gain, feed consumption, feed conversion ratio (FCR)) after being infected with C. jejuni. A total of 36-day-old chicks (DOC) were grouped into 3 based on feed provision, namely, commercial feed group (I), commercial feed group + AGP (II), and commercial feed group + Feed additives (S._cerevisiae) (III). The three groups were further divided into 2 treatments, namely (A) without challenge test (control) and (B) challenge test. Feed mixing was done manually, drinking was given ad libitum and vaccination was according to the field program. Weighing of body weight and remaining feed was done every week. A challenge test with C. jejuni was done on the 21st day with a concentration of 1x109 CFU/mL. The results obtained for overall weight gain in weeks 1 to 3 of each feed group, statistically did not show a significant difference (P>0.05), although the numbers showed a difference. Weeks 4 and 5 of the control group's weight gain statistically showed a significant difference between groups (P<0.05). The challenge test group, week 4 experienced a decrease in weight gain and was not statistically significantly different (P>0.05) but in week 5 there was an increase in weight and was statistically significantly different (P<0.05). Conclusion: Providing commercial feed additives (S. cerevisiae) can increase weight gain, and reduce feed consumption and FCR.
