The aim of this study was to investigate if use of phytogenic feed additive based of bioactive herbal compounds affected coccidian invasions and production parameters in goats. This research was carried out on a flock of adult Boer goats and their offspring owned by the WULS-SGGW’s Sheep and Goat Research Farm in Żelazna. The experimental and control groups were established regarding 14 and 10 does for fecal analysis, respectively as well as 10 and 7 does for milk performance analysis, respectively. Does were at 2–7 lactation and reared 1–2 kids. The addition of herbal feed additive (ADICOX AP) was applied in feeding of experimental group in doze of 200 g per ton of concentrate. Individual fecal samples were collected directly from the rectum from does (beginning and end of trial time) as well as from kids (end of the experiment). The McMaster counting technique and the flotation method was applied for does and kids respectively. The whole experimental time lasted for approx. 3 months since kidding pick and data regarding milk yield of does and body weights of kids were collected in every 2-weeks period. The results indicated addition of ADICOX AP in preventing of coccidiosis in goats caused several observations regarding experimental group such as: I. advantageous course of lactation curve in milked goats, II. higher body weights of kids and higher daily gains during first weeks of rearing, III. significant lower number of oocytes per gram of faeces in adult goats and iv. decrease of highly infected kids. ADICOX AP demonstrated its high usefulness in prevention of coccidiosis in goats. Moreover, the advantageous trends in production traits, both in adult goats and in kids, gave additional benefit, which indicated the possibility of use ADICOX AP in standard breeding practice. Additionally this study also indicated the necessity of searching for naturally based feeding solutions in animal diets which may be helpful in maintaining parasitic infections and could bring better production yields for breeders.
