Adaptability and Bromatological Characterization of Grass Varieties (Cichorium Sp, Plantago Menor, Pennisetum Clandestenium)

Objective: The present research aimed to characterize the bromatological composition of three grass varieties in the flowering stage. Theoretical Framework: The text emphasizes the crucial importance of forage quality in milk production, especially in tropical zones. It highlights that forage quality, determined by its digestibility and nutritional content, varies according to factors such as climate, soil, and management practices. Additionally, the text underscores the need to adjust cow feeding according to their production stage and individual nutritional requirements, considering factors such as body weight, body condition, and forage intake. Method: A non-parametric exploratory investigation was conducted, analyzing three treatments using the statistical software INFOSTAT. MANOVA and the Kruskal-Wallis H test were applied for multivariate analysis, using the Wilks, Pillai, Lauley, Hotelling, and Roy statistical software through a DCA. Results and Discussion: With the values obtained from the Tukey mean test (p>0.05) of the evaluated grasses, kikuyo had protein values of 2.63, crude fiber of 2.24, and fat of 0.30, showing a significant difference. Chicory had a higher range in moisture with 90.45, and its values were 2.01 for protein, 1.41 for crude fiber, 0.30 for fat, and 1.76 for ash. Finally, plantain had values of 1.86 for crude fiber, 2.15 for protein, 87.80 for moisture, 0.24 for fat, and 1.52 for ash. Implications of the research: The implications of this research are highly relevant to the livestock sector, especially in tropical zones. By demonstrating the importance of forage quality in milk production and how factors such as climate, soil, and management practices influence this quality, it opens up a wide range of possibilities to improve the efficiency and sustainability of production systems. Originality/Value: The originality and value of this research lie in its practical and applied approach to a specific reality. While the relationship between forage quality and animal production is a widely studied topic, this research provides a particular perspective by focusing on the specific conditions of tropical zones and providing practical recommendations for dairy producers.
