ABSTRACT An experiment was carried out to evaluate the effect of an herbal choline feed plant additive on the productive parameters and blood metabolites of finishing lambs. Forty male Hampshire × Suffolk lambs (initial body weight of 30.36±3.75 kg) were assigned according to a completely randomized design. Treatments consisted of dietary inclusion of the herbal additive BioCholine at 0, 3, 6, and 9 g/kg dry matter for 56 days. A linear response for herbal choline dose was observed for daily gain, final body weight, feed conversion, blood glucose, and blood phosphatidylcholine as herbal choline level was increased in the diet. Total protein, globulins, and low-density lipoproteins showed a quadratic effect, and there were no effects on intake, Longissimus dorsi area, back fat, blood cholesterol, triglycerides, high-density lipoproteins, or albumins. The inclusion of the herbal choline feed plant additive improved daily gain and feed efficiency of finishing lambs. The choline feed plant additive is a source that can be used to meet choline requirements in small ruminants, as demonstrated by blood phosphatidylcholine and lamb performance.
