ΕΠΙΔΡΑΣΗ ΤΗΣ ΠΡΟΣΘΗΚΗΣ ΛΥΣΙΝΗΣ ΚΑΙ ΒΙΟΤΙΝΗΣ ΣΕ ΥΨΙΘΕΡΜΙΔΙΚΑ ΣΙΤΗΡΕΣΙΑ ΟΡΝΙΘΙΩΝ ΚΕΡΕΟΠΑΡΑΓΩΓΗΣ ΣΤΗΝ ΕΝΑΠΟΘΕΣΗ ΚΑΙ ΣΤΗ ΣΥΝΘΕΣΗ ΤΟΥ ΛΙΠΟΥΣ ...

BROILER-TYPE CHICKS OF TWO COMMERCIAL STRAINS (HUBBARD AND ROSS) WERE USED IN THREE EXPERIMENTS. CHICKS WERE FED ADLIBITUM HIGH ENERGY DIETS WITH SIMILAR CALORIE: PROTEIN RATIO, UP TO 7 WEEK OF AGE. HIGH AMOUNTS OF PLANT ORIGIN FATS (7% COTTON SEED OIL, 7% SUNFLOWER OIL AND 25%, 35% OR 40% FULL FAT SOYBEAN MEAL-FFSBM) WERE ADDED TO THE DIETS, IN COMBINATION WITH LYSINE (NO ADDITION, 20% OR 70% ABOVE REQUIREMENTS) OR WITH BIOTIN (400 MG/KG TO BIOTIN DEFICIENT DIETS). BLOOD WAS TAKEN FROM THREE AVERAGE WEIGHT BIRDS FROM EACH PEN, ONE DAY AT THE END OF 7TH WEEK AND ABDOMINAL FAT AND LIVER FROM THE SAME BIRDS WERE TAKEN. ADDITION OF COTTONSEED OR SUNFLOWER OIL TO THE DIET IMPROVED PERFORMANCE OF MALE AND FEMALE CHICKS. CARCASS WEIGHT WAS INCREASED BUT ALSO WAS INCREASED CARCASS FATNESS. ADDITION OF 25% FFSBM IMPROVED PERFOMANCE IN CONTRARY TO ADDITION OF 35 OR 40%. FATTY ACID COMPOSITION OF ABDOMINAL FAT, LIVER FAT AND SERUM FAT WAS SIMILAR TO THE FATTY ACID COMPOSITION OF THE FAT OF THE DIET. ADDITION OF LYSINE IMPROVED LIVE WEIGHT AT LEVEL 20% ABOVE REQUIREMENTS AND DID NOT CHANGE THE FATTY ACID COMPOSITION OF BODY TISSUES. ADDITION OF BIOTIN, TO BIOTIN DEFICIENT DIETS, IMPROVED PERFORMANCE AND REDUCED THE UNSATURATED FATTY ACID CONTENT OF THE ABDOMINAL FAT. THE FATTY ACID COMPOSITION OF TISSUE FAT WAS SIMILAR IN BOTH SEXESEXCEPT FOR: A) OLEIC ACID, WHICH WAS HIGHER IN ABDOMINAL FAT OF FEMALES AND B)LINOLEIC ACID WHICH WAS HIGHER IN LIVER FAT OF MALES.
