Olive Waste as Feed Supplement: Morphometrical Effects on the Ansa spiralis coli in Lambs

Anatomia, Histologia, Embryologia, Volume 55, Issue 3, May 2026.
ABSTRACT Feedlot systems for small ruminants require nutritionally adequate and viable diets, and the incorporation of olive residues can offer a sustainable and economically advantageous alternative. This study evaluated the effects of including olive waste at 7.5%, 15%, 22.5% and 30% in the diets of Texel × Ile‐de‐France lambs, assessing the ...

Spatial price competition and buyer power in the U.S. beef packing industry

American Journal of Agricultural Economics, Volume 108, Issue 3, Page 771-798, May 2026.
Abstract We develop a spatially‐explicit model of the U.S. beef packing industry to study key questions related to competition in an oligopsony setting. Cattle supplies are modeled at the county level, and packing plants' location, capacity, and ownership are taken as given. Packers procure negotiated cattle by competing in prices in each local (county)
