Abstract

From the age of 9 weeks, 90-90 Kolos, Gourmaud and Babati goose breeds were force fed with 2 different types of technology and 3 types of feedstuff. Force feeding technologies were the traditional Hungarian and Israeli soft groats quick methods. In the case of the latter, feedstuff was fed both in a pre-fermented (Lactobacillus plantarumlactic acid bacteria) form and without fermentation. Frequency of daily force feeding was gradually increased from 2 to 6 until the 21st day of force feeding. Live weight before and after fattening and liver weight were measured in the case of each breed and treatment. Liver quality was also determined. On the basis of our results, differences in liver weight average were significantly influenced only by the genetic property of the breed. Liver quality was also influenced by the method of force feeding of one breed (Babati). Feedstuff tested did not result in significant differences in liver weight or in liver quality. Independently of the breed very close correlation was found between „fattening weight” and liver weight (r=0.98) and between „fattening weight” and liver quality grade (r=–0.97).
