Respuesta a una maniobra inductora de estrés y al tratamiento con un producto hepatoprotector en pollos de engorda

Abstract

STRESS IMPACT PRODUCED IN FATTENING CHICKEN IS ASSESSED IN THIS STUDY (400 BROILERS IN TOTAL, 50% OF EACH SEX). IMMOBILIZATION AND INVERSION MANOEUVRE TO INDUCE CHANGES COMPATIBLE WITH THE STRESS SYNDROME, AND THE EFFECTS OF THE CONTINUOUS HEPATIC PROTECTION (HP) USING A PRODUCT WITH THE FOLLOWING EFFECTS: LIPOTROPIC, CHOLERETIC-CHOLAGOGIC, HYPOCHOLESTEREMING AND HYPOTRIGLYCEREMING AND HEPATIC REGENERATION ENHANCING WERE STUDIED. A FACTORIAL EXPERIMENTAL MODEL IN BLOCKS (FOUR LOTS) TO TWO ROADS WAS USED. FOUR GROUPS (1 = WITH STRESS AND HP, 2 = WITH HP, 3 = WITH STRESS, 4 = CONTROL) WERE FORMED. DEPENDENT VARIABLES REGISTERED DURING 45 DAYS OF THE CYCLE WERE: BODY WEIGHT, DAILY GAIN OF WEIGHT, FEED INTAKE, CONVERSION RATIO, ABSOLUTE WEIGHT OF THE LIVER, WEIGHT OF THE CORRECTED LIVER, GLUCOSE, TRIGLYCERIDES, TOTAL PROTEIN, ALBUMINS, AND GLOBULINS. COMPARING GROUP 3 WITH THE CONTROL ONE, LIVER WEIGHT WAS 28.02 AND 26.68 G, RESPECTIVELY. BODY WEIGHT PRESENTED AN OPPOSITE RELATION (2 266 AND 2 438 G, P < 0.01). THESE FINDINGS COINCIDE WITH THOSE OF OTHER AUTHORS WHO HIGHLIGHT SIMILAR BEHAVIOR OF THESE VARIABLES. BIRDS OF GROUP 1 PRESENTED BODY WEIGHT, DAILY GAIN OF WEIGHT AND TRIGLYCERIDES SIGNIFICANTLY SUPERIOR TO GROUP 3, AND THEIR WEIGHT OF THE CORRECTED LIVER WENT SIGNIFICANTLY SMALLER TO THAT OF THE OTHER GROUPS. THE BEHAVIOR OF THESE LAST TWO VARIABLES COULD CONSTITUTE INDICATIONS TO CORROBORATE THAT THE LIPOTROPIC ACTION CAN BE ATTRIBUTED TO THE USED PRODUCT.
