摘要
The study presents the effect of a varied quantity of pea seed in feed mixes on the production parameters, development of selected internal organs, as well as on the level of selected steroid hormones and dehydrogenase enzyme in quails during the second period of growth. The experiment involved 150 birds. The quails were assigned to three equal-number groups of birds with similar body weight and sex ratio. Feeding of group I was based on the standard feed, whereas the diet of groups II and III was supplemented with 12% and 18% of pea seed, respectively. The diets in all the groups were isoproteinic and isoenergetic. The quails were managed under equal husbandry conditions. After six weeks, the birds were slaughtered and selected organs were dissected, such as alimentary tract, testes, and ovaries. The blood sampled on the slaughter was assayed for testosterone (in males), progesterone (in females), and dehydrogenase (both sexes). The resulting data were processed statistically using one-way ANOVA and the Duncan test.
Feeding of quails with a 12% addition of peas had a positive, significant effect on the final body weight of the females. The body weight of males on day 42 was similar it? all the groups. No significant differences were found in the daily feed intake or the feed intake per unit of gain. Application of feeds containing varied proportion of pea seed did not significantly influence the share of breast muscle in the body weight of males. Its significant decrease was observed in females fed on the 18% pea seed diet. In the groups fed on pea, we found a higher share of small intestine in females and a higher share of liver, however, only it? group Ill females. We observed a negative effect of pea seed in the diet on the blood concentration of testosterone in males.
