| Popis: | New bio-based dietary supplement with micronutrients for livestock was elaborated. The new preparation was tested on laying hens to determine the influence of new biological feed additives on the level of trace elements in egg content. The diet of laying hens (Hy-Line Brown, 30 weeks of age) was supplemented with soya bean meal enriched with Cu(II), Zn(II), Fe(II) and Cr(III) by biosorption. A total of 150 laying hens were divided into five groups: one control and four experimental. In the control group, microelements were supplemented in the inorganic form, whereas in experimental groups, Cu, Zn, Fe and Cr were replaced with soya bean meal enriched with a given microelement ion. The feeding experiment was conducted for 12 weeks and was divided into three series. The results showed that adding the new feed additives to the diet of laying hens had an impact on microelement transfer to eggs, in particular with increased dosing. Eggs were biofortified with iron, zinc and copper and to a lesser extent with chromium. The microelements were accumulated primarily in the albumen because soy protein was the carrier of micronutrient ions in hens' diet. Transfer of trace elements to eggs was not linearly dependent on the dosage of biologically bound microelements in the diet. |
