DNA barcode datasets are a useful tool for conservation and aid in taxonomic identification, particularly in megadiverse tropical countries seeking to document and describe its biota, which is dropping at an alarming rate during recent decades. Here we report the barcodes for several low elevation bird species from northern Colombia with the goal to provide tools for species identification in this region of South America. We blood-sampled birds in a lowland tropical forest with various degrees of intervention using standard 3 × 12 m mist-nets. We extracted DNA and sequenced the COI barcode gene using standard primers and laboratory methods. We obtained 26 COI sequences from 18 species, 10 families and three orders and found that barcodes largely matched (but not always) phenotypic identification (> 90%) and they also facilitated the identification of several challenging passerine species. Despite our reduced sampling, our study represents the first attempt to document COI barcodes for birds (from blood samples) in this part of Colombia, which fills a considerable gap of sampling in this part of South America.

A total of 1,436,000 Ross 380 AP broiler chicks were included in the experiment, which was conducted in two cycles with 20 houses per cycle and 35,900 birds per house. The objective was to evaluate, under field conditions, the impact of a precision biotic (PB) on the growth performance and cecal microbiome of broiler chickens, in comparison to enzymatically hydrolyzed yeast (EHY) and butyrate (BT) in an antibiotic-free diet. Each cycle consisted of six (6) houses under PB supplementation, and 14 houses under the regular dietary program used by the integration.

Cross-view geo-localization (CVGL) aims to determine the capture location of street-view images by matching them with corresponding 2D maps, such as satellite imagery. While recent bird's eye view (BEV)-based methods have advanced this task by addressing viewpoint and appearance differences, the existing approaches typically rely solely on either OpenStreetMap (OSM) data or satellite imagery, limiting localization robustness due to single-modality constraints. This paper presents a novel CVGL method that fuses OSM data with satellite imagery, leveraging their complementary strengths to enhance localization robustness.

Detecting early-stage stress in broiler farms is crucial for optimising growth rates and animal well-being. This study aims to classify various stress calls in broilers exposed to cold, heat, or wind, using acoustic signal processing and a transformer artificial neural network (ANN). Two consecutive trials were conducted with varying amounts of collected data, and three ANN models with the same architecture but different parameters were examined.

Notably, poultry animals-particularly chickens-are recognized globally for their valuable contributions to the food, ornamental, and game economies. Further, more robust local and regional breeds can be parental donors for these area-specific consumable breeds' resilient traits. Game birds that are locally significant economically or on a much smaller scale are frequently excluded from the procedure.
