- Use of indigenous plants for treatment of animals infected with helminth parasites: Herbal infusions of prairie sagewort (Artemisia frigida, family Asteraceae), tansy (Tanacetum vulgare) and garlic (Allium sativum) were tested against ovine internal parasites Nematodirus and Haemonchus spp with the objective to evaluate their antihelminthic activity against common helminths of ruminants. Twenty five local Mongolian sheep, infected naturally with Nematodirus oiratianus and Haemonchus contortus, were grazed on pasture in Taryalan soum county of Khuvsgul aimag province for the duration of the experiment. The efficiency of the infusions (30%) was measured by the percentage reduction in the number of eggs produced by N. oiratianus. The egg count was reduced by 13.3% using prairie sagewort, 15.8% with tansy and 11.3% using garlic. The number of eggs produced by H. contortus was reduced by 22, 20.5 and 17.8%, respectively 5 days after administration of the plant infusions. In untreated (control) sheep infected with N. oiratianus and H. contortus there was little change in egg counts during this period, the levels remaining at 97.8 to 100% of the initial egg counts. The results indicated that infusions of 30% prairie sagewort, tansy or garlic to sheep had significant anthelminthic activity against N. oiratianus and H. contortus leading to a reduction in egg shedding.
- Urea molasses multinutrient blocks have been found to be highly beneficial in several member states (MS). The use of solid urea-molasses blocks, i.e. solid blocks made with urea, molasses, vitamins and minerals, as a supplement for the nutrients deficient in the main feed, offers several advantages, namely, ease of transport, storage and use. It has reduced risks of toxicity compared with other approaches, such as giving a small amount of urea in the drinking water, or sprinkling a urea solution on fibrous feeds before they are fed to animals.
