Bile acids facilitate lipid digestion and nutrient absorption by emulsifying fats and promoting micelle formation in the intestine. Therefore, it was hypnotized that supplementing reduced CP diets with bile acids may enhance fat utilization, improve energy efficiency, and mitigate the negative effects of low-CP diets on broiler performance and nutrient digestibility. Four dietary treatments were arranged in a 2 × 2 factorial layout, with two CP levels (standard and a 30 g/kg CP reduction), with or without 0.2 g/kg bile acids. A total of 840 off-sex male Ross 308 chicks were randomly assigned into 24 floor pens, with six replicates of 35 birds per treatment. From 0 to 42 days post-hatch, there was no interaction between dietary CP and bile acids supplementation for BW, feed intake (FI), FCR, abdominal fat pad, and nutrient digestibility (<em>P</em> &gt; 0.05). As a main effect, reducing dietary CP decreased BW, FI, fat digestibility, and increased FCR and abdominal fat pad (<em>P</em> &lt; 0.01). The reduced CP diet resulted in lower plasma concentrations of valine, isoleucine, arginine, histidine, phenylalanine, leucine, and tryptophan, while increasing lysine, methionine, and threonine concentrations (<em>P</em> &lt; 0.01). Bile acids supplementation enhanced dry matter and protein digestibility (<em>P</em> &lt; 0.05). Bile acids also showed a tendency to increase plasma methionine concentrations (<em>P</em> = 0.055). A significant interaction effect was observed for overall mortality, with bile acids supplementation reducing mortality in birds fed reduced CP diets (<em>P</em> &lt; 0.01). These findings suggest that in reduced CP diets, the current ideal AA profile may be deficient in arginine and histidine, potentially contributing to increased fat pad weight. Elevated wheat-derived non-starch polysaccharide concentrations might lower fat digestibility in reduced CP diets. Supplementation of bile acids in these diets could mitigate endogenous taurine losses and improve overall health in broiler chickens.</div></div>","PeriodicalId":20459,"journal":{"name":"Poultry Science","volume":"104 6","pages":"Article 105107"},"PeriodicalIF":3.8,"publicationDate":"2025-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143769322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 180 female chickens were randomly divided into two groups, with one receiving a basal diet (CON) and one receiving a treatment (PCE) supplemented with 360 mg/kg PCE according to a completely randomized design.

However, broiler behaviour patterns can be valuable for assessing health, welfare and performance. Here, individual feeding patterns of group-housed broilers were studied. Data on feeder visits of 58 randomly selected and subsequently RFID-tagged broilers were used, that were housed in a group of approximately 800 birds in a 45 m² pen. Feed and water were provided <em>ad libitum</em>, with a total of 16 feeders available to the broilers. All feeders except one (due to farm equipment blocking the access) were fitted with an RFID antenna to detect presence of the broilers at the feeders. The number of feeder visits and feeding durations at the individual level during the period from 20 to 30 d old were examined. In addition, birds’ individual body weights (g) were determined at 14, 21, 27 and 35 d of age, and at 21, 27 and 35 d of age gait scores were determined by experienced observers. The feeders used within the pen (i.e., whether feeding occurred in one area or was spread out across the pen) varied between individuals, and for some birds also changed with age. Furthermore, with higher body weights at 14 d of age, the number of different feeders visited in a day was lower (estimate = -0.011, <em>P</em> = 0.002) and the mean feeding bout duration was higher (estimate = 0.130, <em>P</em> = 0.007).

As poultry experts have reported that the presence of PRM is accompanied by a specific scent, opportunities lie in using odor-based detection methods. These methods may offer a fast and reliable alternative for identifying PRM infestations in early stages.
