Effect of feeding Leucaena pallida with concentrate and antihelmentic treatment on growth performance and nematode parasite infestation of Horro ewe lambs in Ethiopia

Abstract

The study was conducted to investigate the effect of supplementing Leucaena pallida in reducing gastrointestinal parasite load and to evaluate growth response of Horro ewe lambs to supplementation and antihelmentic treatment. A total of 32 Horro ewe lambs were randomly assigned to four treatments: Grazing, grazing + antihelmintics only, grazing + 500 g dried Leucaena pallida leaves + 200 g ground maize grain per head/day, and grazing + 200 g noug cake + 200 g ground maize grain per head/day with eight replicates. Feeding L. pallida leaves increased (P < 0.05) growth rates and reduced (P < 0.05) nematode parasite egg counts (Eggs per gram of faeces (EPG)) compared with un-supplemented Horro ewe lambs. Packed cell volume (PCV) was significantly increased (P < 0.05) in Horro ewe lambs supplemented with L. pallida and concentrate and treated with antihelmentic compared to the animals assigned to grazing alone. The results revealed that supplementation of L. pallida with concentrate have beneficial anti-parasitic properties and improved the growth performance of Horro ewe lambs.

Implications of Tannin Containing Plants for Productivity and Health in Small Ruminant Animals: A Review

“…At the end of experimental period, a significant increase in PCV was recorded in goats in the SL group relative to those in no CT group. Similar results have been obtained by Merera et al (2013) and Arroyo-Lopez et al (2014) from infected lambs fed sainfoin. The increased in PCV could be due to reduce number of blood sucking parasites in abomasum and small intestine by CT or improved protein nutrition allowing the host to replace lost protein more rapidly.…”

“…An increased in weight gain has been used as a marker of resilience in nematode infected ruminants. Additionally, a number of studies are also in agreement with these results in parasitized sheep supplemented with L. pallida (Merera et al, 2013), Sainfoin (Arroyo-Lopez et al, 2014) and Lespedeza cuneata (Zyl et al, 2017). Most of CT containing forages are rich in protein content and are more digestible (Torres-Acosta et al, 2012).…”

“…This could be attributed to the CT content in PEA and LES which suppressed parasitic nematodes. Indeed, a large number of studies have shown that CT containing forages improved feed intake of parasitized lambs (Lisonbee et al, 2009;Merera et al, 2013) and goats (Seng et al, 2007;Moore et al, 2008;Sokerya et al, 2009;Amit et al, 2013). However, some results showed that feed intake of nematode infected sheep (van Zyl et al, 2017) and goats (Lopes et al, 2016) were not affected by feeding tanniniferous forages (Table 2).…”

“…Studies show that supplementation with CT containing forages alleviate impacts of parasitism in sheep and goats (Arroyo-Lopez et al, 2014;Singh et al, 2016). A pasture trial conducted by Merera et al (2013) showed that supplementation with Leucaene pallida significantly increased packed cell volume (PCV) of nematode infected Horro lambs compared to those assigned grazing alone. In the United States, Moore et al (2008) evaluated the anthelmintic effects of S. lespedeza (SL) on H. contortus infected goat kids randomly assigned to two dietary treatments consisting of 75% SL hay (CT) or Bermuda grass (no CT) and 25 % concentrate.…”

“…Cependant, cette supposition est à prendre avec beaucoup de précautions, car les travaux de Vitti et al (2005) et de Fluck et al (2013) ont montré que les tanins condensés, même à de faibles concentrations, ont un impact positif sur la fermentation des légumineuses fourragères. Ces effets bénéfiques ont pour conséquences non seulement un gain de poids vif (Chala et al, 2013) mais en plus, une action indirecte sur les parasites gastrointestinaux grâce à l'amélioration de la réponse (résistance et résilience) de l'hôte contre les vers (Hoste et al, 2011). De plus, d'autres métabolites secondaires autres que les tanins, peuvent avoir des capacités de liaison aux protéines ou avoir des propriétés anthelminthiques (Hoste et al, 2006).…”
