| description | There is currently worldwide interest in phytogenic feed supplements (PFSs) because they can lead to improved animal production. The scope of the present study was to observe the impact of a feed supplement containing carvacrol (CAR) and limonene (LIM) on the performance and parasitological status of sheep. The feed supplement decreased the plasma levels of β-hydroxybutyrate (<i>p</i> < 0.001), triglycerides (<i>p</i> = 0.014), nonesterified fatty acids (<i>p</i> = 0.021), and fructosamine (<i>p</i> = 0.002) in lactating ewes after 42 days of supplementation, while the average live weight (<i>p</i> = 0.002) and average daily weight gain (<i>p</i> = 0.001) of their twin suckling lambs increased significantly by the end of the study. In another experiment, fattening lambs fed the same supplement showed a decrease in fecal egg number of gastrointestinal nematodes (<i>p</i> = 0.02) but no differences in live weight, average daily gain, or mean number of <i>Haemonchus contortus</i> nematodes in the abomasum. The results highlighted that the inclusion of carvacrol and limonene in the feed of lactating ewes effectively increased the weight gain of the suckling lambs, presumably due to the ewes’ improved energy, but further studies are needed to elucidate the effects of carvacrol and limonene against gastrointestinal parasites. |
