Enhancing Nutritional Quality of Livestock Feed Through Environmentally Controlled Fodder Cultivation Systems

Abstract

Nutrition of livestock has become a major aspect in ensuring that livestock yield, health and sustainability of livestock systems, but traditional production is increasingly questioned due to changes in the environment, which reverses nutrient composition, digestibility and supply of gravage food. In order to overcome these limitations, this research paper compares the performance of environmentally controlled fodder cultivation system that involves the use of hydroponic technology to grow nutrient enriched green fodder under optimum micro climate. Seeds of barley and maize were grown in a controlled environment whereby temperature, humidity, photoperiod and rhythm of water-nutrient delivery were strictly controlled to minimise the abiotic stress and to maximise the nutrient intake during crop germination. Comparative laboratory and field testing showed that hydroponically cultured fodder had significantly better crude protein content (1218%), enhanced dry matter digestibility and reduced levels of neutral detergent fibre (NDF) and acid detergent fibre (ADF) than adapted hydroponically-grown counterparts in the field. Several studies on livestock feeding, by feeding cows on hydroponic fodder showed significant improvements in feed palatability, voluntary feeding, and an increase in average rate of growth and weight gain, as well as reduced, that is, lower, physiological stress biomarkers in foods, including cortisol and blood urea nitrogen; hence, improved metabolic efficiency and the use of nutrients. Also, the controlled-environment system facilitated production throughout the year with limited water requirement and no reliance to the soil fertility, underscoring how it can be adopted in regions where climate conditions experience variability, where there is a water scarcity problem, and where land is limited. Comprehensively, the results demonstrate that hydroponic fodder systems optimised to the environment are a good and sustainable alternative to the conventional fodder production due to the provision of constant nutrient content, implementation of better livestock production, and the resistance of the animal agriculture to climate challenges. These findings highlight the significance of incorporating controlled-environment technologies into the current livestock feeding approaches to reinforce the food safety, improve the productive, and viable agricultural growth.
