Myoglobin (MB) gene encodes the protein of myoglobin, which is a protein found in muscle tissues that plays a crucial role in binding and storing oxygen. This study aimed to analyze the polymorphism of the MB gene, examine its relationship with the meat mineral content, and analyze its expression in the liver and thigh muscle tissue of IPB-D2 chicken. A total of 55 IPB-D2 chickens were used in this study. Identification of the gene polymorphism, quantification of the mineral content, and gene expression were performed using the direct sequencing method, the Atomic Absorption Spectroscopy (AAS) method, and the qRT-PCR, respectively. Chicken thigh muscle and liver tissues were used as the source of mRNA in this study. The statistical analysis methods used were the chi-square test to test Hardy-Weinberg equilibrium, and the T-test for mineral association analysis and gene expression analysis. IPB-D2 chicken on average contains 17.81, 0.22, 16.50, and 0.34 mg/kg of Fe, Se, Zn, and Mn, respectively. Two SNPs were found in 5’UTR of the MB gene, namely SNP g.17 G>T and SNP g.25 T>C. Genotype TT (g.17 G>T) and genotype CC (g.25 T>C) were significantly (P<0.05) associated with high Fe content in IPB-D2 chicken. The gene expression analysis showed that MB mRNA expression in the liver was not statistically different between high Fe (TT/CC) and low Fe (GG/TT and GT/TC) genotype combination. Meanwhile, in the thigh muscle, MB mRNA expression in TT/CC genotype combination was significantly higher than GG/TT and GT/TC genotype combination (P<0.05). These results suggest that the identified polymorphisms in the IPB-D2 MB gene could serve as references for investigating similar gene in other chicken breeds, especially regarding Fe, Se, Zn, and Mn mineral content.

Earthworms (Lumbricus rubellus) are one of the soil organisms with a protein content of approximately 76%, providing significant benefits to human life. It is necessary to transport livestock/animals from their place of origin to the destination for processing or further cultivation in order to maximize the utilize of earthworms. During transportation, various challenges are encountered, leading to a decline in the performance of earthworms. The aimed of this research was to study the influence of different transportation durations on the performance of earthworms. A Completely Randomized Design (CRD) was employed with three different transportation duration treatments and three replications. Further analysis would be conducted using Duncan’s multiple-range test if the results differred significantly. Variables observed in this study included the conditions of the media pH, media temperature and humidity, environmental temperature, and humidity, weight loss and earthworm mortality. The results indicated that transportation duration significantly differs (P<0.05) in affecteding the weight loss and mortality earthworms. The 3-hour transportation treatment resulted in the highest weight loss (82.33 g, equivalent to 55.63%) and mortality (411.87 g, equivalent to 91.07%).

Genetic improvements in broiler chickens represent a major advancement in the poultry industry. Through selective breeding techniques, broiler chickens now exhibit remarkably fast growth and improved feed conversion efficiency. Observations were conducted by comparing data from the previous period with suboptimal management and the new period with optimal management. The Coops with good management were observed over one period (approximately 6 weeks). The result were made by comparing the data between the suboptimal management with the improved management, and both sets of data were compared with the international Cobb 2021 standards. The measured variables included: depletion (%), feed consumption (g/bird), body weight (g/bird), feed conversion, performance index, and profit. Improvements in environmental conditions or milieu (temperature, humidity, feed management, water, ventilation, and litter) resulted to more optimal production performance. Depletion, feed consumption, body weight, and feed conversion met the company’s standards (body weight 2.5 kg, feed conversion 1.45, and performance index 450). The final performance was categorized as excellent, with a performance index of 512. Additionally, the profit from the new management was higher at Rp. 9,772 per bird than the old management Rp. 2,570 per bird.

The growing chicken population in Indonesia reflects the expanding poultry farming industry. To maintain chicken health and treat diseases, vitamins and antibiotics are commonly used, with guidelines for their use changing over time. To understand usage trends, data from PT Tekad Mandiri Citra (TMC) in Bandung is needed. This study evaluates the sales patterns of poultry antibiotics and vitamins in the veterinary drug industry between 2020 and 2022, with a focus on farm health and sustainability. Additionally, a SWOT analysis will be used to replace colistin antibiotics, based on changes to the Minister of Agriculture Regulation No. 14 of 2017. Data were processed using Microsoft Excel 2019 for descriptive analysis. The results show that 79% of broiler farms use antibiotics, and 81% use vitamins. In 2022, the most common antibiotics were from the fluoroquinolone group (34%), and the most used vitamins were from the miscellaneous group (35%). The SWOT analysis for 2021-2022 indicates that replacing colistin products has been successful.

Fan settings (wind speed) in the cage must be adjusted to the age and weight of the chickens. Any movement of the wind at a certain speed will have an impact on the difference between the actual temperature read on the thermometer and the effective temperature felt by the chickens. This is because there is a cold temperature effect (wind chill effect) due to air movement. On the 1st floor of the KTM cage, there was an error setting the fan on which caused the wind speed to be higher than necessary, causing a wind chill effect. This case caused the performance of the chickens in the 1st-floor cage not to reach the target. To get the ideal temperature and wind speed in the cage, the effort needed is to adjust the fan to turn on taking into account the wind chill effect. Based on the results of considering the wind chill effect in the cage, the value of feed intake, body weight gain, and body weight at the age of 7-35 days appear to be higher with a low feed conversion value and a higher production index.

In ovo feeding is one way to increase poultry productivity by providing additional nutrition during the incubation period and can increase embryo growth. Many implementations of in-ovo feeding techniques have been carried out on various types of poultry, but a summary of the use of in-ovo feeding on various types of poultry has never been reported, therefore this study was conducted. This review article aims to determine the use of in-ovo feeding in various types of poultry. This study was conducted based on literature studies by analyzing secondary data and synthesizing research from various data sources originating from nationally accredited journals and reputable international journals that discuss the use of in-ovo feeding in various types of poultry. The study shows that the implementations of in-ovo feeding for various types of poultry have been mostly applied to broiler chickens and native chickens, but only a few in geese, ducks, and quails. In-ovo feeding has several advantages for enhancing nutrition and health, including preserving normal physiological status and preventing disease, so that poultry productivity can be increased.

The increasing demand for chicken meat in Indonesia has encouraged the development of superior localchickens such as IPB D1, which have the ability to utilize local feed and exhibit rapid growth. Thisstudy aimed to determine the role of zinc, chromium, and lemuru oil supplementation on the digestivesystem development and internal organs functionality of IPB D1 chickens. A total of 100 twelve-weekold IPB D1 chickens were assigned to four treatment groups: control (P0), feed supplemented withzinc and chromium (P1), feed supplemented with lemuru oil (P2), and feed supplemented with zinc,chromium, and lemuru oil (P3). A Completely Randomized Design (CRD) was applied, and significantdifferences were analyzed using Tukey’s post hoc test. The findings revealed no significant impact ofsupplementation on the relative length of the digestive tract. Nonetheless, a significant increase in thepercentage of gallbladder weight was observed in the P3 group (0.09%–0.13%). In contrast, the heartweight percentage was significantly reduced compared to the control group (0.48%–0.58%). Theseresults indicate that combined supplementation of zinc, chromium, and lemuru oil may modulate lipidmetabolism and cardiovascular function in IPB D1 chickens. Further investigations are required toestablish optimal dosages and assess the long-term implications on the performance of IPB D1 chickens.
