2025-06-24T14:38:13+00:00

The Tumor Protein P53 Inducible Nuclear Protein 1 (TP53INP1) gene is expected to be a crucial candidate for mineral content. This research aimed to analyse the genotype polymorphism and investigate its association with the TP53INP1 gene and sheep mineral content. To analyse gene polymorphisms and conduct an association study, 30 rams of Javanese thin-tailed sheep were utilised. The NlaIII restriction enzyme was applied to investigate the genotype polymorphism of the TP53INP1 gene through Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP). Regarding the association with analysing TP53INP1, a General Linear Model (GLM) was used. The findings indicate that the TP53INP1 gene shows polymorphism, revealing three distinct genotypes identified by the results: AA, AG, and GG. The genotypes were detected using the Hardy-Weinberg Equilibrium (HWE) principle. According to the association analysis, a significant association (P < 0.05) was found between the TP53INP1 gene and mineral content, particularly iron (Fe). A higher mineral content was associated with the GG genotype, whereas a lower mineral content was related to the AA genotype. The TP53INP1 could be the candidate gene for sheep's mineral content.

2025-06-25T02:29:24+00:00

The purpose of this study is to identify the effect of parity on calving interval and gestation period in Balinese cattle in CV. Darmapuri Agro Semesta Klungkung Bali. The research method used in this study is a survey method conducted on female Balinese cows that have undergone Artificial Insemination (AI) at least once, are pregnant, or have given birth, as well as the results of interviews and direct observations. The research material used in this study consists of Balinese cattle, specifically 10 female Balinese cows, which are selected annually over five years, resulting in a total of 50 heads. There are five treatments, namely 1st parity (P1), 2nd parity (P2), 3rd parity (P3), 4th parity (P4), and 5th parity (P5). The variables observed were gestation period and calving interval. Data were analysed using analysis of variance with a completely randomised design, followed by the Least Significant Difference test. The results of the study showed that parity had a highly significant effect (P < 0.01) on gestation period and calving interval. The duration of gestation from shortest to longest in sequence is P5 (272.00 ± 23.07 days), P2 (276.90 ± 24.16 days), P1 (307.00 ± 20.65 days), P3 (322.40 ±35.14 days), P4 (325.70±27.62). Meanwhile, the calving interval values are P1 (0.00 ± 0.00 days), P2 (351.90 ± 85.61 days), P4 (376.90 ± 103.69 days), P5 (383.30 ± 94.58 days), and P3 (603.20 ± 218.30 days). The second (P2) and fifth (P5) gestation periods were significantly shorter than those of the first parity (P1). The shortest gestation period is at the 5th parity, while the shortest calving interval is at the 2nd parity. This study concludes that the various parities on calving interval and gestation period show a significant difference.

The Effect of Fermented Coffee Husk on The Growth Performance of Biromaru Kampung Chicken

2025-06-24T09:47:29+00:00

This study aimed to determine the effect of providing fermented coffee husk waste on the growth performance of Biromaru Kampung chickens. The high price of conventional feed has led to the exploration of more economical alternatives, one of which is the utilisation of agricultural waste, such as coffee waste. The nutritional value of coffee husk waste can be increased and its antinutrient content reduced through fermentation using microorganisms. The study was carried out for six weeks in Palu, Central Sulawesi, using a Completely Randomized Design (CRD) consisting of four treatments and five replications: P0 (basal feed), P1 (90% P0 + 10% non-fermented coffee waste), P2 (90% P0 + 10% fermented coffee waste with Saccharomyces cerevisiae), and P3 (90% P0 + 10% fermented coffee waste with Effective Microorganisms 4). Feed consumption, body weight gain, and feed conversion ratio were measured as the variables of interest. The results indicated that feed consumption was significantly increased in treatments P1 and P3, while body weight gain and feed conversion ratio were not significantly affected. Providing fermented coffee waste as an alternative feed for Biromaru Kampung chickens resulted in a significant increase in feed consumption, particularly in treatments P1 (10% non-fermented coffee waste) and P3 (10% fermented coffee waste with Effective Microorganisms 4). Although body weight gain did not differ significantly between treatments, there was a tendency for an increase in P1 and P3. Additionally, treatment P3 demonstrated the best feed conversion efficiency compared to the other treatments. Overall, fermented coffee husk waste has the potential to increase feed consumption and efficiency. However, its impact on body weight gain still needs further research to understand the mechanism of its influence in more depth.

Addition of Moringa Leaf Flour (Moringa oleifera L) in Rations on the Quality of Quail (Coturnix coturnix japonica) Eggs

2024-11-26T01:27:19+00:00

This study aims to evaluate the use of moringa leaf flour (Moringa oleifera L) in rations on the quality of quail eggs. The researchers designed four treatments and five replications: P0, a ration without the use of Moringa leaf flour (control); P1, a ration containing 5% Moringa leaf flour; P2, a ration containing 10% Moringa leaf flour; and P3, a diet containing 15% Moringa leaf meal. These were analysed using ANOVA. The results showed that the use of Moringa leaf flour up to 15% had a significant effect (P<0.05) on yolk color but had no significant impact (P>0.05) on egg weight, yolk index, albumen index, haugh unit, shell weight, and thick shell. Based on the research results, incorporating Moringa leaf flour into rations up to 15% can enhance yolk colour without reducing egg weight, yolk index, albumen index, Haugh units, shell weight, and shell thickness.

Seasonal Adaptation in Feed Management: Assessing Forage and Feedstuff Variations in Small-Sized Dairy Farms in Boyolali, Central Java

2025-06-05T03:10:21+00:00

Small dairy farms in tropical regions frequently encounter feed shortages and quality fluctuations between seasons, which can substantially affect milk production. This research aimed to evaluate the ability of small-scale dairy farms to adapt to and manage feed fluctuations in response to seasonal changes. The research employed an exploratory design, with samples collected using nested sampling methods. Three samples were collected according to the season, specifically during the dry season (August 2024) and the rainy season (January 2025), from the Cepogo and Selo Subdistricts in Boyolali. Feed samples collection was conducted in five stages: 1) desk study of the research area; 2) field visiting; 3) feed samples; 4) forage samples collection; and 5) feed analysis using proximate analysis (AOAC, 2005). The results showed differences in feeding management among farmers related to their dairy animal structures. The highest dry matter content in the forage was found in rice straw (60.4% DM), which dominated dry season use, while the highest crude protein content was observed in calliandra (23.5%) among the forages. Five coproducts have high dry matter content with varying crude protein and crude fibre levels. The research concluded that small-sized dairy farms can adapt and manage feed fluctuations based on seasonal changes by making forage and concentrate choices available.
