Early stages of tooth development in the harbor porpoise Phocoena phocoena
Abstract Here we describe the stages of tooth development in toothed whales on the basis of the harbor porpoise (Phocoena phocoena). The aim of the study was to find out whether these stages are identical to those of other mammals analyzed so far although toothed whales are homodont and monophyodont.

Identification Epitope on VP4 Protein of Senecavirus A Recognized by a Monoclonal Antibody
This study aims to identify conserved antigenic epitopes on the SVA VP4 protein using monoclonal antibodies, providing valuable tools for further exploring its functions and developing detection methods. SVA VP4 protein was expressed in Escherichia coli and purified with High‐Affinity Ni‐Charged Resin FF.

The effects of restricted nursing (RN) and the administration of a bovine appeasing substance (BAS) on days −8 and 0 in relation to weaning were evaluated. Both strategies were effective in improving the growth performance of beef calves. Regarding welfare, BAS ‐especially on day 0‐ was more effective than RN.

The bioactive substances we extracted from Lycium barbarum residue (LBR) have a typical polysaccharide structure. When 1.80% LBR was used to replace maize in the diet, the average daily gain of rossbred Simmental was significantly increased, and anti‐inflammatory ability was improved. In addition, LBR improved the fecal microbial composition, increased

Follicle Stimulating Hormone in Cattle Breeding: Fundamentals, Innovations, and Scope
FSH is crucial in cattle reproduction, with exogenous administration enhancing breeding and embryo production. Recombinant FSH offers advantages over pituitary‐extracted variants, including fewer injections, reduced stress, and safer production. These innovations improve breeding efficiency, optimize reproductive outcomes, and contribute to sustainable

Cows with ketosis during the perinatal period often experience damage to the liver, a core metabolic organ, thereby exacerbating the disease's inherent vicious cycle. This study indicates that serum 3‐IAA concentrations were reduced in ketotic cows and show a significant negative correlation with hepatic TG content.
