The effects of Acinetobacter glutaminase-asparaginase (AGA) on protein and energy requirements were evaluated in mice bearing Ehrlich ascites tumors. In an initial experiment with normal mice, a zero protein diet resulted in a significant decrease in carcass nitrogen, liver nitrogen, and carcass en ergy relative to the animals on a normal, low, or high protein diet. In a second experiment, mice...

Introduction Formulating diets according to the ideal protein concept allows for maximizing nitrogen utilization and minimizing nitrogen excretion [1]. One primary benefit of ideal protein is that once a ratio is established for a certain age, one can calculate the requirement of all other amino acids under a variety of conditions based on the digestible lysine (dLys) requirement [2]. Digestibl...

Sharon A. Clay Department of Plant Science, South Dakota State University, Brookings, SD 57007 Microarray analysis was used to identify changes in gene expression in corn leaves collected from plants at the V11–14 growth stage that resulted from competition with velvetleaf. The plants were grown in field plots under adequate N (addition of 220 kg N ha 1) and irrigation to minimize N and water s...

Termites effectively feed on many types of lignocellulose assisted by their gut microbial symbionts. To better understand the microbial decomposition of biomass with varied chemical profiles, it is important to determine whether termites harbor different microbial symbionts with specialized functionalities geared toward different feeding regimens. In this study, we compared the microbiota in th...

Urea, a non-protein nitrogen for dairy cows, is rapidly hydrolyzed to ammonia by urease produced by ureolytic bacteria in the rumen, and the ammonia is used as nitrogen for rumen bacterial growth. However, there is limited knowledge with regard to the ureolytic bacteria community in the rumen. To explore the ruminal ureolytic bacterial community, urea, or acetohydroxamic acid (AHA, an inhibitor...
