Nutrient Cycling Potential from Manure from Heifers Fed Four Bermudagrass Cultivars.

The main focus of the first abstract is the evaluation of nutrient cycling potential from manure of heifers fed four different bermudagrass (Cynodon dactylon) cultivars. The study found that despite differences in ruminal digestion among cultivars, manure from these diets had little to no effect on subsequent forage production, nutrient uptake, or soil nutrient status in a controlled greenhouse setting. The second abstract addresses the future challenges and responsibilities of animal and forage scientists in sustainably increasing the supply of nutritionally valuable animal-source foods amid global population growth. It emphasizes the essential ecological role of ruminant animals in converting inedible biomass into nutrition and calls for increased research funding and professional training to support sustainable intensification of animal agriculture despite prevailing anti-animal agriculture sentiments.
