“…Meanwhile, the studies with sheep could only include 10% of diet. The latter is consistent with recent studies showing a greater ability of adult goats to eat more polyphenol-rich materials compared to adult sheep [41,118] and the same was recently found for weaned animals [49]. The study with naturally infected goats showed non-significant FEC reductions (25-27% compared to the control diet) after three weeks of ingestion of feed containing SCG [57].…”

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 given to assess the potential antiparasitic activity of less conventional resources, represented by different agro-industrial by-products (AIBPs). This review presents in vitro and in vivo results obtained with a range of tannin-containing AIBPs of various geographical and botanical origins, namely AIBP of nuts, temperate and tropical barks, carob, coffee and cocoa. They tend to confirm the “proof of concept” for their antiparasitic effects and also for other aspects of ruminant production in an agro-ecological context. Socio-economic aspects of the exploitation of such non-conventional resources are also discussed as potential models of the circular economy, by using waste. The different modes of use of these resources are presented in this review, as well as strengths, weaknesses, opportunities, and threats (SWOT) analyses to illustrate the advantages and limitations of on-farm use.

“…The selection of resistant sheep against GIN has been carried out mainly in lambs and to a lesser extent in adult ewes ( González-Garduño et al ., 2014 ; Palomo-Couoh et al ., 2016 , 2017 ). Typically, parasite loads in the humid tropics are high which leads to dismal health states and occasionally death of lambs ( Jaimes-Rodríguez et al ., 2019 ). Selection of both lambs and adult ewes in production is carried out in many sheep farms.…”

Summary The objective was to identify the optimal stage of production to evaluate the resistance of Pelibuey ewes against gastrointestinal nematodes (GIN). Faecal egg count (FEC) was used to classify the ewes as resistant, sensible or intermediate against GIN. Forty-seven ewes were mating during 30 d. The gestation was verified by ultrasonography, and the breeding date was used to calculate the productive stages. Faeces were taken weekly to determine the FEC. Blood samples were taken to determine the packed cell volume (PCV), the peripheral eosinophils count (PEC), plasma protein concentration (PP), and Immunoglobulin A (IgA) against Haemonchus contortus. The body condition score (BCS) was recorded at each visit. Six moments during the study (early, mid and late gestation; early, mid and late lactation) were considered. The ewes were classified according to FEC (mean FEC ± three standard errors). The higher FEC occurred during all lactation stages than during early and mid-gestation stages (P<0.05). PCV, PP, and BCS during early gestation stage were higher than shown during the lactation stages (P<0.01). The PEC and IgA were higher during all lactation stages than early and mid-gestation stages (P<0.05). Concerning the type of birth, double births showed higher FEC than single birth (P<0.01). The highest values of accuracy (100 %) and concordance (Youden's J = 1.0) were found during early lactation. Therefore, it is concluded that the optimal stage of production to evaluate phenotypic resistance against GIN infections in Pelibuey ewes was during the early lactation.

“…Se ha demostrado que solo logran sobrevivir en este ecosistema algunas especies de NGI: Haemonchus contortus, Trichostrongylus colubriformis, Strongyloides papillosus, Oesophagostomum columbianum y Trichuris spp. (Torres-Acosta et al, 2004;Martínez-Ortíz-de-Montellano et al, 2007;Jaimez-Rodríguez et al, 2019). Se demostró que las fases de vida libre de los NGI (huevos, L1, L2 y L3), presentes en las heces de los animales y en la vegetación, tienen una marcada estacionalidad y solo pueden sobrevivir en la época de lluvia, principalmente entre agosto y noviembre.…”

Background. Small ruminants that graze in the low deciduous forest (LDF) face problems related to malnutrition and gastrointestinal nematode infections (GIN). Over the past 30 years, FMVZ-UADY researchers have conducted extensive research to understand the interaction between small ruminant nutrition, plants consumed in LDF, and GINs. Objective. Review the work carried out in the FMVZ-UADY to explain why these problems of malnutrition and GIN infection occur and how to solve them. Main findings. Research shows that the complex interaction between small ruminants, LDF plants, and GINs helps explain malnutrition problems and GIN infections. Both of these problems have also been shown to abate through dietary supplementation, which must be designed to deliver the limiting nutrients in the LDF. Producers can use criteria such as weight gain and body condition score (BCS) to monitor that their animals are nutritionally adequate. To maintain strong resilience and resistance against GINs, growing animals should achieve> 100 g / day weight gain and adults should maintain> 2.5 BCS. It has also been confirmed that many LDF plant species contain secondary compounds (SC) that can affect the biology of different life stages of GIN, so they could be used as nutraceuticals. However, some SC can also adversely affect the digestion and absorption of nutrients in sheep and goats, so they must be used with care. The presence of plants containing SC with anthelmintic activity has made it possible to explore the capacity of animals to self-medicate. In these studies, it has been shown that goats do not express a “curative” self-medication behavior against GINs but do exhibit “preventive” self-medication behaviors that could allow them to limit their GIN burdens. However, animals seem to favor a preventive behavior aimed at avoiding nitrogen:energy imbalances in the consumed diet. Implications: Many LDF plant species have a high potential to be used for both nutritional and medicinal purposes in small ruminants, therefore, these species could be considered as a nutraceutical resource. Conclusions. The work carried out in the last 3 decades has shown us that the optimal use of LDF by sheep and goats will be achieved through a better understanding of the interaction between animals, their GIN and the plants of the LDF.
