Equids, including horses, donkeys, and mules are reared for meat and milk productions, for social activities and as sport and working animals. Gastrointestinal nematodes (GINs) are one of the main health problems in equids worldwide. Studies on GINs have uncovered a diversity of species in donkeys, especially small strongyles also known as Cyathost...

The performance and health of does and growing rabbits were compared over three consecutive reproductive cycles for three groups of 20 nulliparous does and their litters (DS0, DS13, DS26) fed isonutritive feeds containing 0, 13 or 26% dehydrated sainfoin (DS, Perly cultivar). Feed intake, live weight and fertility of does were not affected by DS fe...

The use of plants and their metabolites stands as a promising option to tackle parasitic infections by gastrointestinal nematodes (GIN) in integrated control strategies. Still, the influence of environmental and phenological factors, and their interactions, in the wild on the metabolomics and biological properties of target plant species, is often...
Article
Full-text available
Gastrointestinal nematodes (GIN) infections, commonly called-worms‖, affect both humans and animals. In veterinary medicine, the search for alternatives to control GIN is now considered a priority because of increasing resistances to commercial anthelmintics. The use of bioactive plants and related secondary metabolites is one of these alternatives...

Previous studies have illustrated that different bioactive legume fodders containing condensed tannins might represent one of the options for integrated sustainable control of gastrointestinal nematodes (GIN) in ruminants, which may help address the worldwide development of resistance to synthetic anthelmintics. More recently, impetus has been give...
Chapter
Anthelmintic resistance (AR) is a growing concern for effective parasite control in farmed ruminants globally. Combatting AR will require intensified and integrated research efforts in the development of innovative diagnostic tests to detect helminth infections and AR, sustainable anthelmintic treatment strategies and the development of complementa...

Sainfoin is a candidate worth to be explored for rabbit feeding because of its nutritional properties. In this study, growing performances of rabbits and reproductive performances of does were compared, over 3 reproductive cycles, when fed isonutritive feeds containing either 0, 13 or 26% dehydrated sainfoin (DS: Perly cultivar). Doe performances (...

Our trial aimed to study the gastro-intestinal parasitism in pasture raised rabbits, during three seasons: winter 2014/2015, summer 2015 and spring 2016. For every season, at weaning two groups of five movable cages (three rabbits per cage) were disposed either in a sainfoin or a grass pasture. Nematodes eggs and Eimeria oocysts were counted on a w...

Background: Mediterranean shrub species cover more than 70% of the total area in Tunisia and in summer when the herbaceous species have wilted, they constitute feeding resource for livestock. The use of tanniniferous shrubs seems to be a good alternative to control gastrointestinal nematodes infections in small ruminants. This study evaluated the i...

Gastro-intestinal parasitism in pasture raised rabbits was studied during three seasons: winter 2014, summer 2015, spring 2016. For every season, two groups of five movable cages (3 rabbits/ cage) were disposed from weaning to 100d. old, on a sainfoin or on a grass plot. A high prevalence of Trichostrongylus sp. (93% of rabbits) and a 50% increase...

Haemonchus contortus is a parasite species that affects the health and production of grazing small ruminants in different parts of the world. Scanning electron microscopy (SEM) is an important tool for the study of parasites' morphology and taxonomy as it generates images that appear 3D and are generally easier to interpret than optical microscopy...

Coccidiosis caused by Eimeria species is a common, occasionally severe infection causing economic losses in the rabbit industry. The potential anticoccidial effect of tannin-containing resources fed in rabbits has been previously reported in vivo. However, the mode of action remains unknown. During this study, we investigated in vitro the anticocci...

Article
Due to high prevalence and large pathogenicity, Haemonchus contortus is the main gastrointestinal nematode in tropical and subtropical regions. This species is responsible for severe economic losses to sheep and goat breeders in Brazil. The control of this parasite is currently compromised, mainly, due to anthelmintic resistance. In the search for...

The present study explored the anthelmintic effects of condensed tannins (CT) in carob (Ceratonia siliqua) pods fed to sheep against gastrointestinal nematodes. Three independent in vivo trials tested whether i) carob pod (CaBP)-containing feed had an anthelmintic effect and if yes, which was the optimal concentration in the diet; ii) whether this...
Article
Because of their continuing expansion, wildlife ruminant species that prosper in rural landscapes may be increasingly affected by and/or contribute to the circulation of certain generalist pathogens also infecting domestic ruminants, when they share common spaces or resources. In this study, we aimed to test the hypothesis that parasitism with gast...

Worldwide, parasitic gastrointestinal nematodes continue to threaten animal health, welfare and production in outdoor breeding systems of small ruminants. For more than 50 years, the control of these parasitic worms has relied on the use of commercial synthetic anthelmintics. However, anthelmintic resistance in worm populations is nowadays widespre...

Ruminants select nutritious feeds and avoid deleterious ones by relying on a learning process. We tested the hypothesis that they may similarly be able to select feeds for their medicinal properties, i.e. to self-medicate. Our experimental model was lambs infected with gastrointestinal nematodes (GIN), and the temperate legume sainfoin (Onobrychis...

The variable anthelmintic efficacy of condensed tannins (CT) against gastrointestinal nematodes may depend on CT concentration, composition or fate along the digestive tract. We analyzed CT concentration and composition by acetone-HCl-butanol and thiolysis coupled to HPLC-MS in digesta and feces of lambs. Lambs had been infected with Haemonchus con...

Condensed tannins (CTs) account for up to 20% of the dry matter in forage legumes used as ruminant feeds. Beneficial animal responses to CTs have included improved growth, milk and wool production, fertility, and reduced methane emissions and ammonia volatilization from dung or urine. Most important is the ability of such forages to combat the effe...
