Abstract

Background: Kaolin may improve quail performance by maintaining intestinal integrity and improving nutrient absorption. Objective: To evaluate the overall performance, egg quality, moisture, nitrogen and calcium content in the excreta, intestinal morphology and financial analysis of kaolin in Japanese quail feed during the production phase. Methods: A total of 192 Japanese quails, distributed in a completely randomized design with four treatments and six repetitions with eight birds each, were used. Kaolin levels added to the diet were 0, 1.5, 3.0, and 4.5%. Results: Kaolin reduced feed consumption. Additionally, egg production, feed conversion and viability increased. Moisture, nitrogen and calcium in the excreta decreased. Height and width of the intestinal villi increased with increasing levels of kaolin in the diet. Kaolin had no effect on egg quality. Inclusion level of 1.5% kaolin allowed for greater economic gains. Conclusion: Kaolin improved performance, intestinal morphology, and reduced the moisture, nitrogen and calcium contents in the excreta. Egg quality remained unchanged with the addition of kaolin, and the best economic response resulted with the addition 1.5% kaolin.

日本鹌鹑生产阶段饲料中高岭土的含量

背景：高岭土可以通过维持肠道完整性和提高营养吸收来提高鹌鹑的生产性能。目的：评价日本鹌鹑饲料生产过程中高岭土的综合性能、蛋品质、水分、排泄物中氮钙含量、肠道形态及财务分析。方法：共使用192只日本鹌鹑，以完全随机的设计进行分配，四次治疗，六次重复，每只八只。添加到饲料中的高岭土含量分别为0%、1.5%、3.0和4.5%。结果：高岭土降低了饲料消耗。此外，鸡蛋产量、饲料转化率和生存能力都有所提高。排泄物中的水分、氮和钙减少。肠道绒毛的高度和宽度随着饮食中高岭土含量的增加而增加。高岭土对鸡蛋品质无影响。1.5%高岭土的掺入水平可带来更大的经济效益。结论：高岭土改善了生产性能，改善了肠道形态，降低了排泄物中的水分、氮和钙含量。随着高岭土的加入，鸡蛋的品质保持不变，添加1.5%高岭土的经济效果最好。

期刊介绍： The editors of Revista Colombiana de Ciencias Pecuarias (RCCP) welcome the submission of original manuscripts on experimental and clinical studies associated with the broad areas of animal sciences and veterinary medicine as they interface with biochemistry, molecular biology, physiology, pharmacology, toxicology, pathology, microbiology, parasitology, immunology and epidemiology. The scope of the journal includes studies of basic and applied research in animal management and production, feeding and nutrition, reproduction, breeding, genetics, animal welfare and behavior; as well as animal production focussed from biotechnology, soil science, agrostology, silvopastoral systems, livestock economics and the environment. The criteria for acceptance of papers submitted for publication are originality, quality and clarity of the content. Each contribution must be based on original, unpublished research that has not been simultaneously submitted to other journals. All papers will be peer reviewed. All authors bear responsibility for ensuring the integrity and quality of their reported research. It is the author''s responsibility to secure permission to use figures or tables that have been published elsewhere. Contributions may be classified as original research, review, rapid communication, clinical case studies or methodological articles, as well as news/commentaries or letters to the editor. Most review articles are invited by the editor. Authors interested in submitting a review article should contact the corresponding editor. Rapid publication of original manuscripts is a goal of the journal. Manuscripts must be written in English. Each manuscript is considered for publication with the understanding that it has not been simultaneously submitted to any other journal. Upon acceptance for publication, papers are subject to editorial review and revision.
