Abstract
We analyzed the effect of a herbal (phytoncides) supplement on the morphology of internal organs and intestinal morphometry of broiler chickens. The study was conducted on 60 birds divided into 3 groups (n = 20): one control and two experimental. Starting at 3 weeks of age, chickens from the experimental groups were given water with the addition of a preparation based on concentrated natural components in two doses: 1 and 2 ml/l. Group 1 was given the supplement twice for 3 and 5 days, and group 2 once for 3 days. After slaughter at the age of 40 days, the proventriculus, gizzard, duodenum, jejunum, ileum, cecum, liver, spleen, kidneys, bursa of Fabricius (BF), lungs, and pectoral muscles were sampled for histological analyses. Additionally, villi height (VH) and crypt depth (CD) in the duodenum, jejunum, and ileum were measured. The results did not show statistically significant differences between the groups in the number of histological lesions in the organs and tissues sampled. Morphometric evaluation showed statistically significant differences between the groups (p < 0.05) for VH and CD in the duodenum and ileum.
期刊介绍:
"Medycyna Weterynaryjna" publishes various types of articles which are grouped in the following editorial categories: reviews, original studies, scientific and professional problems, the history of veterinary medicine, posthumous memoirs, as well as chronicles that briefly relate scientific advances and developments in the veterinary profession and medicine. The most important are the first two categories, which are published with short summaries in English. Moreover, from 2001 the editors of "Medycyna Weterynaryjna", bearing in mind market demands, has also started publishing entire works in English. Since 2008 the periodical has appeared in an electronic version. The following are available in this version: summaries of studies published from 1999 to 2005, full versions of all the studies published in the years 2006-2011 (in pdf files), and full versions of the English studies published in the current year (pdf). Only summaries of the remaining studies from the current year are available. In accordance with the principles accepted by the editors, the full versions of these texts will not be made available until next year.
All articles are evaluated twice by leading Polish scientists and professionals before they are considered for publication. For years now "Medycyna Weterynaryjna" has maintained a high standard thanks to this system. The review articles are actually succinct monographs dealing with specific scientific and professional problems that are based on the most recent findings. Original works have a particular value, since they present research carried out in Polish and international scientific centers.
