Parasitic Gastroenteritis in\u00a0Goats<\/h4>\n
<\/p>\nGastrointestinal nematodes (roundworms) are responsible for major economic losses to the livestock industry globally. As with all other grazing livestock, heavy infections in goats can lead to poor productivity, ill-health and death. The gut nematodes which typically infect goats are similar to those that will cause disease in sheep and other small ruminants: Haemonchus contortus<\/a>, Teladorsagia<\/a>, Trichostrongyles, Nematodirus<\/a>, Oesophagostomum <\/em>and Cooperia<\/em>. However, it must be highlighted that unlike sheep and cattle goats have not evolved to produce a strong immunity against gastrointestinal worms, and therefore remain susceptible all throughout out their lives. Gut worm infestations in goats range from acute disease, with frequent rates of high mortality, to various levels of chronic disease with varying degrees of morbidity.<\/div>\n <\/strong><\/p>\n
\nParasitic gastroenteritis is almost always caused by a mixture of multiple nematode species and a broad overview of their general epidemiology and biology can be found on the main Parasitic Gastroenteritis in Ruminant page here<\/a>.<\/div>\n<\/div>\n<\/div>\nGoats are particularly susceptible to Haemonchus contortus<\/em><\/a> (Barbers pole worm<\/a>), but as this specific gut worm does not conform to the same characteristics as other gut roundworms, it has a whole page dedicated to it. Click here to learn more<\/a>.<\/p>\nGoats differ in their immunological response and have different feeding behaviours compared to sheep and cattle therefore a small summary specific to PGE in goats is found below.<\/p>\n
How do goats get worms?<\/h3>\n
The adult worms reside in the gut and the females lay thousands of eggs which are passed out with faeces onto the pasture. Under suitable climatic conditions these eggs hatch and larva will emerge and reside on the pasture until ingested by a goat, and then will migrate to the gut, where they develop into adult worms. The full life cycle is explained in more detail on the main Parasitic Gastroenteritis in Ruminants<\/a> page.<\/p>\nWhat are the\u00a0main clinical signs to look out for?<\/h3>\n\n- Reduce growth and weight loss caused by loss in appetite and poor gut function<\/li>\n
- Reduced milk production<\/li>\n
- Reduced and poor quality fibre growth<\/li>\n
- Diarrhoea<\/li>\n
- Anaemia<\/li>\n
- Sudden death (taken from Harwood, 2006<\/a>)<\/li>\n<\/ul>\n
What is different about parasitic gastroenteritis in goats?<\/h3>\n
Unlike sheep and cattle goats do not<\/u><\/strong> develop strong immunity to gut worms. Under normal grazing conditions goats have been shown to be more severely infected than sheep, with much higher burdens and more damage to the gut, and this is due to their inferior ability to elicit an immune response (Torres-Acosta and Hoste, 2008<\/a>). Consequently, in rangeland grazing (extensive grazing) sheep were found to be more infected than goats, and this is attributed to the goats feeding behaviour in which they prefer to browse rather than graze.<\/p>\nBrowsing behavior of goats<\/h3>\n
Goats limit contact with infective larvae due to their characteristic feeding behavior. They are natural browsers eating shrubs and plants as opposed to sheep which primarily graze from the ground. This distinct feeding behavior should be exploited in goats as worms eggs that have been passed with dung, will hatch on the ground and the microscopic larvae are only capable of migrating short distances up the proximate pasture, and the physical structure of some plant and forage species (e.g., height, spines, and thorns) will inhibit this migration, making them safer for consumption.<\/p>\n

Control and Prevention of Worms in Goats<\/h4>\nStrategies for controlling worms in goats<\/h3>\n
A review written by a team if scientists in Australia evaluated the current ‘Toolbox’ of parasite control measures goat farmers can employ (Kearney et al.,<\/em> 2016<\/a>). This review is directed at Haemonchus<\/em>, nevertheless some of the strategies are relevant to general parasite control implementation. The ‘Toolbox’ consists of the following:<\/a><\/p>\n\n- Immunonutrition<\/a><\/li>\n
- Bioactive forages<\/a><\/li>\n
- COWPs<\/a><\/li>\n<\/ol>\n
\n- \n
Immunonutrition<\/h3>\n<\/li>\n<\/ol>\n
The term ‘Immunonutrition’ refers to the use of nutrition to boost immunity (Kearney et al., 2016<\/a>). There are many published studies which demonstrate a direct relationship between nutrition and immunity in small ruminants. Research shows that by improving nutrition the immune response (host resistance) and the ability to maintain production during a high parasitic burden (resilience) also improves. A consequence of gut worm pathology is disruptions in protein absorption and metabolism, and retention of other minerals, hence the target nutrient is often protein. For example, a high protein diet fed to West African Dwarf does increased resilience (better weight gain, body condition, pregnancy and kidding\/lactation performance) and enabled the reproducing does to better cope with some of the clinical consequences of parasitism such as reduced feed intake and GI symptoms (Nnandi et al.,<\/em> 2009<\/a>).<\/p>\n<\/a>Many studies has shown that goats respond to supplementary feeding with improvement in resilience over resistance, and this is attributed to the acknowledged lower aptitude of goats to develop an effective immune response against gut worms (Kearney et al., 2016<\/a>).<\/p>\nMore about nutrition and PGE can be found here<\/a>.<\/p>\n\n- \n
Bioactive forages and plant secondary metabolites<\/h3>\n<\/li>\n<\/ol>\n
There are a myriad of active compounds within plants and the utilisation of forages containing active compounds has an important role to play in animal health, particularly goats (Kearney et al., 2016<\/a>). Many plants have been suggested as having anthelmintic properties, although many have not stood up against rigorous scientific testing. Tannins have been under intensive scrutiny and are generally known to have anthelmintic, antibiotic, antiseptic and antifungal properties. However, high concentrations of condensed tannins reduce feed digestibility, feed intake and consequently lower production. Tannins affect dietary protein availability, inactivate digestive enzymes and irritate the GI tract (Kearney et al., 2016<\/a>).<\/p>\n<\/a>Chicory has shown both anthelmintic activity under both in vitro and in vivo experimental conditions, and reduction of the development\/survival\/migration of larvae due to sward structure (Marley et al., 2006<\/a>).<\/p>\nLearn more about pasture composition and PGE here<\/a>.<\/p>\n\n- \n
Copper Oxide Wire Particles (COWP) and Haemonchosis in Goats<\/h3>\n<\/li>\n<\/ol>\n
Copper oxide wire particles (COWPs) are copper boluses used by farmers to treat copper deficiency in cattle. They release copper wire particles throughout the GI tract, and raise copper concentrations in the abomasum. COWPs have demonstrated high anthelmintic activity against Haemonchus<\/em>, but nil effects on Teladorsagia<\/em> and Trichostrongylus<\/em>, under both natural and experimental conditions (Chartier et al., 2000a and 2000b<\/a>). COWPs create an unfavourable environment for Haemonchus<\/em> and causing the expulsion of the adult worms (
