“…Several in vitro and in vivo studies suggest condensed tannins have anthelmintic effects against ruminant nematode parasites. Livestock feeding on plants with tannins such as sulla (Hedysarum corarium) and sericea lespedeza (Lespedeza cuneata) have lower nematode burdens and lower faecal egg counts than those eating plants of similar quality without tannins (Niezen et al, 1998;Coop and Kyriazakis, 2001;Min and Hart, 2003;Min et al, 2004). Chicory (Cichorium intybus) contains an array of condensed tannins and other phenolic compounds including sesquiterpene lactones, coumarin and caffeic acid derivatives that reduce the need for commercial anthelmintics in young farmed deer (Hoskin et al, 1999).…”

“…However, not only do herbivores manifest partial preferences (Westoby, 1978), they also ingest substantial amounts of PSMs (Provenza, 1995 andVillalba et al, 2004), likely due in part to their health and medicinal effects. If we view nutrients from another angle, they can also enhance resilience and resistance of the host to disease (Coop andKyriazakis, 1999 and. For instance, protein intake increases the resilience of livestock to parasitic infection by increasing host productivity, and when protein bound to tannins bypasses the rumen and is subsequently digested in the small intestine, that protein enhances immunity to nematode infections (Coop and Kyriazakis, 2001;Ketzis et al, 2006).…”

Self-medication and homeostatic behaviour in herbivores: learning about the benefits of nature’s pharmacy

Traditional production systems have viewed animals as homogeneous 'machines' whose nutritional and medicinal needs must be provided in a prescribed manner. This view arose from the lack of belief in the wisdom of the body to meet its physiological needs. Is it possible for herbivores to select diets that meet their needs for nutrients and to write their own prescriptions? Our research suggests it is. Herbivores adapt to the variability of the external environment and to their changing internal needs not only by generating homeostatic physiological responses, but also by operating in the external environment. Under this view, food selection is interpreted as the quest for substances in the external environment that provide homeostatic utility to the internal environment. Most natural landscapes are diverse mixes of plant species that are literally nutrition centres and pharmacies with vast arrays of primary (nutrient) and secondary (pharmaceutical) compounds vital in the nutrition and health of plants and herbivores. Plant-derived alkaloids, terpenes, sesquiterpene lactones and phenolics can benefit herbivores by, for instance, combating internal parasites, controlling populations of fungi and bacteria, and enhancing nutrition. Regrettably, the simplification of agricultural systems to accommodate inexpensive, rapid livestock production, coupled with a view of secondary compounds as toxins, has resulted in selecting for a biochemical balance in forages favouring primary (mainly energy) and nearly eliminating secondary compounds. There is a global need to create a more sustainable agriculture, with less dependence on external finite resources, such as fossil fuels and their environmentally detrimental derivatives. Self-medication has the potential to facilitate the design of sustainable grazing systems to improve the quality of land as well as the health and welfare of animals. Understanding foraging as the dynamic quest to achieve homeostasis will lead to implementing management programs where herbivores have access not only to diverse and nutritious foods but also to arrays of medicinal plants.

“…O aumento do OPG no periparto tem sido relacionado à demanda nutricional das ovelhas, principalmente por proteína, no final da gestação e início da lactação (29,31) . Diversos trabalhos têm mostrado redução do OPG com a suplementação proteica no periparto (29,(32)(33)(34)(35)(36) .…”

Resistência À Verminose E Suplementação Proteica No Periparto: Efeito No Parasitismo E No Desempenho Reprodutivo De Ovelhas Do Grupamento Racial Pantaneiro

ResumoOs objetivos do trabalho foram avaliar o efeito do grau de resistência à verminose e da suplementação proteica nos índices reprodutivos e no parasitismo em ovelhas do grupamento racial Pantaneiro. As ovelhas foram classificadas pelo número de ovos de nematodas por grama de fezes (OPG) como resistentes (RR), sensíveis (SS) e intermediárias (RS), e submetidas (SUPL) ou não (NSUPL) à suplementação durante o terço final da gestação e na lactação. Em dois ciclos reprodutivos, a cada 28 dias, as ovelhas foram pesadas e tratadas com anti-helmínticos quando o OPG apresentava-se ≥ 4000. O peso das ovelhas não foi influenciado pelo grau de resistência aos nematódeos e a suplementação teve efeito no peso somente no período em que foi ofertada. As taxas de natalidade e de desmame não foram influenciadas pelo grau de resistência e pela suplementação. A taxa de mortalidade de crias foi menor no grupo SUPL. A taxa de mortalidade de ovelhas foi três vezes mais elevada no grupo SS em relação ao grupo RR e o peso das crias foi menor no grupo SS em relação aos grupos RR e RS. Os três grupos mostraram picos no OPG durante o terço final da gestação, mas as médias foram sempre menores no grupo RR que, no geral, necessitaram 2,5 vezes menos tratamentos anti-helmínticos que as SS. A suplementação não apresentou correlação com o OPG e com o número de tratamentos anti-helmínticos. A classificação de ovelhas pelo OPG em resistentes aos nematodas proporcionou menor número de tratamentos antihelmínticos, menor taxa de mortalidade de ovelhas e peso maior das crias ao nascimento.

“…Se analisarmos bem os resultados, notamos uma grande tendência na redução dos ovos do controle negativo, bem próxima à dos tratamentos. Sem dúvida alguma podemos afirmar que esse acontecimento se deve ao fato das galinhas estarem em cativeiro, sendo bem cuidadas, com um espaço amplo por ave, alimentadas com ração, sem estresse, longe da presença de aves de vida livre e de outros animais, e seguindo todos os preceitos de higiene, o que são fatores essenciais para redução natural da infecção, acarretando em aumento na habilidade para enfrentar as consequências adversas do parasitismo, ou limitando o estabelecimento de larvas infectantes, o desenvolvimento e a fecundidade dos nematóides, causando até mesmo a eliminação dos parasitas já estabelecidos no aparelho digestivo (Fraser et al 1996, Coop & Kyriazakis 2001, Permin et al 2002, Bricarello et al 2005, Veríssimo 2008, Lima et al 2011. Também podemos observar o valor do controle positivo abaixo dos tratamentos naturais, o que demonstra uma maior eficácia da planta frente ao produto comercial (Oliveira 2003).…”

Norte Fluminense Darcy Ribeiro, estado do Rio de Janeiro, no período de 2011 a 2012. O objetivo foi testar in vitro e in vivo a eficácia da planta medicinal Chenopodium ambrosioides Linnaeus, 1786 (erva-de-santa-maria), nas formas fitoterápica e homeopática, como meios alternativos para o controle de endoparasitos de Gallus gallus Linnaeus, 1758 (galinha caipira), um sério problema que afeta a criação e desempenho de aves domésticas, ocasionando morte quando muito intenso, retardo de crescimento, redução do ín-dice de conversão alimentar e aumento na suscetibilidade às doenças infecciosas. As metodologias utilizadas foram preconizadas por Coles et al. (1992) The aim was to test in vitro and in vivo the effectiveness of the medicinal plant Chenopodium ambrosioides Linnaeus, 1786 (santa maria herb) regarding phytotherapeutic and homeopathic alternative methods to control endoparasites of Gallus gallus Linnaeus, 1758 (free range chicken), a serious problem affecting domestic poultry performance causing losses, retarded development, decreased food conversion rate and increase of susceptibility to infectious diseases. In vitro essay demonstrated high reduction rate on eggs eclosion inhibition (97.18%), and in vivo essay showed high fecal eggs counting reduction rate (91.67%). Presence of the genera Ascaridia (35.00%), Capillaria (30.00%), Heterakis (25.00%) and Strongyloides (10.00%) was displayed by this survey. The plant C. ambrosioides showed upper rates front traditional products (Thiabendalol/Mebendazol) as well as to those ones advocated by the Brazilian Ministry of Agriculture and the World Health Organization as effective.INDEX TERMS: Chenopodium ambrosioides, santa maria herb, Gallus gallus, endoparasitosis.
