The Influence of Cage Density, Addition of Fans, and Selenium Supplementation on the Performance and Climatic Conditions of Duck Cages

Introduction

Duck farming is a significant industry worldwide, providing a source of income for many farmers and contributing to the global food supply. However, the performance and climatic conditions of duck cages can have a significant impact on the health and productivity of ducks. Factors such as cage density, the addition of fans, and selenium supplementation can affect the temperature, humidity, and level of ammonia in the cage, as well as physiological responses such as respiratory frequency and rectal temperature. In this study, we aimed to evaluate the influence of these factors on the performance and climatic conditions of duck cages.

Research Methods

The research design used in this study was a split split plot design, with three main factors. The main factor was the use of fans (F1: without fan and F2: with fans), the child's factor was the use of selenium (S1: without selenium and S2: with selenium), and the second child factor was the density of the cage with three treatments, namely D1 (3 tails/0.5 m²), D2 (4 tails/0.5 m²), and D3 (5 tails/0.5 m²). Each treatment was divided into three groups based on initial body weight. Selenium supplementation was given through feed.

The data obtained was then analyzed using variant analysis (ANOVA) and continued with the Duncan test if there were significant differences at the 0.05% level.

Research Results

The results of this study showed that the use of fans, selenium supplementation, and cage density have a significant influence on performance and climate conditions in the cage. There is a significant interaction between the use of fan and selenium supplementation to the level of corticosterone hormone, as well as between the density of the cage and the increase in weight, feed conversion, temperature, humidity, and ammonia level.

From the results of the analysis, the best treatment was found in treatment that uses a fan and selenium supplementation with a density of 4 tails/0.5 m² (F2S2D4). This treatment shows optimal results in terms of weight gain, feed conversion efficiency, and better temperature and humidity conditions.

Additional Analysis and Explanation

Selenium is known to have an important role in reducing oxidative stress and increasing the immune system in poultry. In the context of this study, selenium supplementation has proven effective in controlling stress hormones in ducks, which can affect overall performance. In addition, the presence of fans in the cage serves to increase air circulation, which contributes to temperature and humidity regulation, creating a more comfortable environment for ducks.

The density of the cage is also a factor that needs attention. Density that is too high can cause strict competition for feed and water, as well as increasing stress due to limited space. By using the ideal density, as in the treatment with 4 tails per 0.5 m², ducks can move more freely, which results in an increase in performance.

Conclusion

This study provides a clear picture of the importance of good cage management, which includes the use of fans, proper nutritional supplementation, and appropriate density settings to increase duck productivity. It is hoped that these findings can be a reference for farmers to optimize the condition of the cage in order to achieve the best results in duck cultivation.

Recommendations

Based on the results of this study, the following recommendations can be made:

Farmers should use fans in the cage to increase air circulation and regulate temperature and humidity.
Selenium supplementation should be given through feed to control stress hormones and increase the immune system of ducks.
The density of the cage should be set at an ideal level, such as 4 tails per 0.5 m², to allow ducks to move more freely and increase performance.

Limitations

This study has several limitations, including:

The study was conducted in a controlled environment, which may not reflect real-world conditions.
The sample size was limited to 144 ducks.
The study only evaluated the influence of cage density, addition of fans, and selenium supplementation on performance and climatic conditions, and did not consider other factors that may affect duck productivity.

Future Research Directions

Future research should aim to:

Evaluate the influence of other factors, such as light intensity and water quality, on duck productivity.
Investigate the effects of different types of fans and selenium supplementation on duck performance and climatic conditions.
Conduct a larger-scale study to confirm the findings of this study and provide more generalizable results.
