This study presents SwiftWeigh, a rapid and non-invasive calf weighing system using top-view 2D point cloud data. By extracting key body measurements and applying an ensemble prediction model, the method achieves high accuracy while reducing stress and labor, offering strong potential for precision livestock farming.

This study investigated the ileal digestibility of amino acids in rapeseed meal from different sources for 13- and 28-day-old broilers. The results showed that the interaction between the source of rapeseed meal and age of broilers influenced the ileal digestibility of most amino acids, and older chickens (28 days old) digested the protein more efficiently than did younger ones (13 days old). These results provide a reference for the efficient utilization of rapeseed meal in broiler diets.

Functions of mammalian testicular Sertoli cells (SCs) are vital for spermatogenesis. Exogenous supplementation of taurine could enhance function of porcine SCs. However, how taurine induces the proteomics change to affect the function of SCs remains unknown. Four-dimensional data-independent acquisition quantitative proteomics profiled 109 differentially expressed proteins, which were involved in multiple signaling pathways. Western blotting validated two DEPs (GAS6 and HDAC5). These findings provide critical insights into using taurine to mitigate acute heat stress and regulate male reproductive function.

Dairy cow nutrition is crucial not only for milk production, but also for the health and well-being of the animals, directly impacting the dairy industry. This study reveals that protein supplementation methods, such as protection with binding agents, can improve feeding behaviour and reproductive performance in cows. These results have significant implications for producers, as more efficient feeding can lead to more sustainable and profitable milk production.

Corn silage is a valuable source of energy, fiber and protein in ruminant diets. However, its quality largely depends on the anaerobic fermentation process and storage conditions. This study evaluated the effect of packing films with different oxygen transmission rates on the compositional quality of corn silage, finding that low oxygen permeability films improve aerobic stability and increase soluble carbohydrate content without altering other key parameters compared with conventional films. This offers a practical tool for optimizing the preservation of high-quality feed.
