Studiul comparativ al indicilor de creştere a puilor de carne

Abstract

The study of broilers development in different lots at different times of the year showed that there were no significant differences between the values of body weight in group I and III. At the end of the chicks growth the average of body weight was 2254,4 g or lower than in the first group of chickens with 7,6%, but not more enhanced as compared with group II with 19,8%.Analyzing the values of slaughter yield there was found that this index was higher in group III being 82,2 %, in group I the index was 81,7% and the lowest index was in group II - 80,9%, the difference being in groups II and III of 1,3% and 0,5%.It can be concluded that in group I and III chickens reared in the farm during April-May and September-October had better growth results than chickens reared in June-July.
