The main findings included significant linear and quadratic increases in quail's body weight and body gain with marked improvement of FCR (<em>P</em> < 0.05) without obvious alterations in carcass traits (<em>P</em> > 0.05). Moreover, dietary treatment with naringenin distinctly improved quail's hematology and biochemistry with prominent hypolipidemic effects assured by the significant lowering of cholesterol, TG, LDL, and VLDL. The levels of superoxide dismutase (<strong>SOD</strong>), catalase (<strong>CAT</strong>), glutathione peroxidase (<strong>GPx</strong>), reduced glutathione (<strong>GSH</strong>), immunoglobulins (IgA, IgM, and IgG), complement 3, and lysozyme were increased with naringenin supplementation. The presence of naringenin in quail's diet significantly reduced the presence of different microbial populations in the cecum of growing quails.

The active metabolite of vitamin D<sub>3</sub>, 1,25-dihydroxyvitamin D<sub>3,</sub> plays pivotal roles in mineral homeostasis, bone health, and immune systems which are essential for protection against BCO. Thus, we hypothesized that supplementation with a <em>Solanum glaucophyllum</em>-derived source of 1,25-dihydroxyvitamin D<sub>3</sub> (1,25(OH)<sub>2</sub>D<sub>3</sub>-glycosides) would be an effective measure to control lameness. Here, we report the optimum concentration of 1,25(OH)<sub>2</sub>D<sub>3</sub>-glycosides supplementation in reducing BCO by comparing the inclusions of 0 µg/kg, 0.5 µg/kg, 1.0 µg/kg, and 2.0 µg/kg of 1,25(OH)<sub>2</sub>D<sub>3</sub>-glycosides. The application of 1.0 µg/kg of 1,25(OH)<sub>2</sub>D<sub>3</sub>-glycosides reduced lameness by 53.7%, which reciprocally differed (<em>P</em> < 0.05) from 0 µg/kg and 0.5 µg/kg but was similar (<em>P</em> > 0.05) to 2.0 µg/kg.

Preference tests indicated either no particle size preference, or a preference for particles > 2.8 mm. In a second experiment, reducing pellet quality of 5 mm pellets to increase the amount of fines had no effect on weight gain and FCR from 10 to 34 d of age, but when diets consisted of finely ground wheat as compared to coarsely ground wheat, the feed intake was higher and FCR was poorer. When offered feed with particles > 4.0 mm, 2.8 to 4.0 mm, 1.6 to 2.8 mm and < 1.6 mm, broilers ate more particles 1.6 to 2.8 mm than > 4.0 mm at 12 d of age, while no clear particle size preferences were observed at older ages. These data confirm that diets pelleted through a 5 mm die can be used even from day-old, and that broilers can handle a moderate reduction in pellet quality of 5 mm pellets without compromising performance. A high versatility of broiler chickens to particle size variations, and a preference for larger particles than currently assumed even at a very young age, may explain these results.</p></div>","PeriodicalId":15240,"journal":{"name":"Journal of Applied Poultry Research","volume":"33 3","pages":"Article 100436"},"PeriodicalIF":1.9,"publicationDate":"2024-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1056617124000357/pdfft?md5=1eba858ea82e82afa4a3ed5c26e72da1&pid=1-s2.0-S1056617124000357-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140780152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
