EVALUATION OF LACTOGEN POTENTIAL CHARACTERISTIC TO GOATS MAINTAINED IN DIFFERENT TECHNOLOGICAL SYSTEMS
C. Pascal, C. Cristian
The main objectives of the research were represented by evaluating the influence factors in expressing the lactogen potential of goats from the Carpatina breed in Romania. In this regard were formed two groups of goats with similar characteristics in terms of the number of lactation, season of calving, age. Two lots were established that have benefited from the same nutritional requirements but one was maintained permanently in stabulation and the other was maintained on pasture. In order to assess production potential were planned control actions placed at 50, 100, 150, 200 and 225 days from the time of parturition. The method used to determine the quantity of milk milking each day of control, was based on the recommendations made by the International Committee for Animal Recording, method AT4 and for weighing was used an instrument with an accuracy of ± 5 g. The estimation of the average total production of milk was carried out using the method described by Fleischmann and the testing differences was done using Tukey Test. The obtained results show that in the case of the batch maintained permanent indoors the milk production was higher with 12.32% and on the interval of the first 150 days of lactation produce over 70% of the average quantity of lactation. On the basis of the results obtained it is concluded that stabulation maintenance positively influences performance levels.
