- Gastrointestinal worms are by far the most prevalent of the internal parasites that can affect alpacas. Stomach worms are common place, and it is likely that the majority of animals in your herds will have a number of worms and worm eggs, particularly if you have other classes of stock sharing the same paddocks. A regular worming program will reduce the numbers of worms present and will prevent the problems associated when the numbers multiply and become too great a burden for an animal. There are, however, a few other internal parasites that are less common but can adversely affect alpacas and other classes of stock. To date we have discussed intestinal worms and there is one more parasite of note that can on occasion reside in the intestinal tract of an alpaca and that is the Tapeworm or Cestode. Like all ruminants alpacas are susceptible to a wide range of internal parasites of varying degree of concern to the breeder. Some minor infestations often may go unnoticed for months, if not years, whereas others, if left unchecked, can and do all too often, prove to be fatal.
- One of the major advantages of keeping alpacas is the low maintenance required in their upkeep. In comparison to other classes of stock, alpaca come out head and shoulders (not to mention neck) ahead. One particular area of advantage is the alpaca’s comparatively low parasitic burden. That is not to say, however, that alpacas are not affected by internal parasites. Like all ruminants alpacas are susceptible to a wide range of internal parasites of varying degree of concern to the breeder. Some minor infestations often may go unnoticed for months, if not years, whereas others, if left unchecked, can and do all too often, prove to be fatal.
- Drench resistance is generally regarded as the most economically important sheep health problem in Australia today with an estimated 90% or more farms experiencing the phenomena. There is no sheep drench on the market today that is not affected to some extent. Unless unnecessary drenching is reduced, the cost of drench resistance to the sheep industry alone is estimated in excess of $700 million per annum in the next five years. Less well documented but equally well known are drench resistance problems in other livestock industries.
