[Weight and chemical makeup of the liver of geese during fattening].
Experiments were carried out with regard to certain changes in the liver of geese during their fattening period. The observations were made before the fattening of the geese, namely on the 5th , 10th, 15th, 20th, 25th and 33rd days of the fattening. It was established that during the fattening period the weight of the liver was constantly increasing, especially between the 20th and 25th days. During the fattening their water contents decreased. This tendency was most pronounced after the period of pecking was over. As the process of fattening advanced, the dry substance in the liver increased and the highest increase (by 10.21%) was observed during the interval between the 15th and 20th days. The percentage of the total lipids in the liver increased progressively up to 18.9 times. In the case of unfattened geese the satiated free butyric acids prevailed. In the process of fattening their quantity decreased, whereas that of the unsatiated butyric acids increased.
