Efecto del extracto de diente de león (taraxacum officinale), sobre el comportamiento productivo y enzimas hepáticas séricas en pollos de engorde.

Abstract

The present research entitled "EFFECT OF THE EXTRACT OF DANDELION (Taraxacum officinale), ON PRODUCTION BEHAVIOR AND SERIAN HEPATIC ENZYMES IN BROILER CHICKENS", evaluated in 240 broilers, males of the Cobb genetic line, of one day of age, the productive yield and serum values of liver enzymes at 30 and 45 days of age; the chickens were distributed in four treatments: T0 = control, T1 = diet + 0.5 liters of T. officinale extract per ton, T2 = diet + 1 liter of T. officinale extract per ton and T3 = diet + 1.5 liters of extract of T. officinale per ton, of six replicates each one. We used a completely randomized design with analysis of variance and Tukey test at 5%. T2 showed a better weight gain (P<0.001) with 3088 g/bird, compared to the other treatments (T3 = 3039.3 g/bird, T0 = 2985.3 g/bird and T1 = 2979.5 g/bird), in food consumption there were no differences (P=0.293), the feed conversion in T2 was better (P<0.001) to reason of 1.82 g/g, T2 revealed the best European Efficiency Index (P<0.001) with a value of 291.5, as well as the higher yield to the channel (P<0.0001) with a percentage of 76.1%. With regard to serum hepatic enzymes (ALT, AST, GGT and FA) at 30 and 45 days, a better response of these analytes (P<0.0001) was evidenced in T2. Given these results, it is inferred that the incorporation of the extract of T. officinale in the diet at 0.1% in this one, improves the productive performance of the broilers and the hepatic response of these to their incorporation.
