Development of animal feed from Azolla microphylla to increase production efficiency of goat farms in South of Thailand.
Article in BMC veterinary research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMeat goat production in Thailand, particularly among smallholder farmers, is a sustainable enterprise with significant growth potential due to increasing livestock farming. However, the reliance on high-cost imported feed ingredients, such as soybean meal, poses economic challenges. This study aimed to evaluate the use of Azolla microphylla as a cost-effective alternative protein source in goat diets, potentially replacing soybean meal to improve production efficiency. Conducted at Rajamangala University of Technology Srivijaya, the experiment involved 25 healthy crossbred Boer goats assigned to five treatment groups with varying levels of Azolla (0%, 25%, 50%, 75%, and 100% replacing soybean meal) in a completely randomized design. Over 90 days, data on feed intake, weight gain, nutrient digestibility, and rumen fermentation characteristics were collected.
resultsResults indicated a significant decrease in crude protein and nutrient digestibility with increased Azolla inclusion, particularly at higher replacement levels, while overall dry matter intake remained stable. Although ruminal pH and temperature were unaffected, ammonia nitrogen levels decreased, suggesting altered protein metabolism. Additionally, total volatile fatty acid concentrations peaked at the 25% Azolla level, indicating optimal fermentation efficiency.
conclusionsThese findings demonstrate that Azolla microphylla can effectively replace up to 50% of soybean meal in goat diets, offering a sustainable strategy to reduce production costs and enhance the efficiency of meat goat farming in southern Thailand. Further research is needed to optimize dietary formulations and improve the nutritional profile of Azolla to maximize its potential as an alternative feed ingredient.
