Sustainable alternatives to high environmental input feed ingredients are important to reducing the environmental impact of animal agriculture. Protein and oil extracted from cultivation of black soldier fly (Hermetia illucens) larvae (BSFL) on waste feedstocks such as manure, food waste and plant residues could be a suitable source of nutrients. The oil from BFSL contains large amounts of saturated fatty acids, particularly lauric acid, and may be a more sustainable alternative to palm and coconut oils that are currently used in calf milk replacers in many parts of the world.

This study is the first to conduct a sero-surveillance of Bovine Tropical Theileriosis (BTT) caused by the protozoan parasite Theileria annulata (T. annulata) using a recombinant Tams1 protein-based dot-ELISA in cattle, and to compare its efficacy with plate-ELISA, single PCR, nested PCR, and blood microscopy. The goal was to identify the most effective method for the early and accurate detection of theileriosis, which significantly impacts livestock through reduced milk yield and increased mortality.

Food wasted in primary and secondary education institutions creates nutritional losses, financial inefficiencies, and environmental degradation. While there is some evidence of how particular interventions within schools may influence the amount of waste created, there is little recent information about typical levels of food waste generated in U.S.

Calf management is important for the development, health, and welfare of the animals. In this follow-up study, we evaluated calf management practices on dairy farms in Austria using an online questionnaire in 2021 and 2022. We tested the hypothesis that farmers changed calf management on their farm within these 10 years.
