Effects of Lecithin on Some Nutritive, Productive and Ruminal Indices in Young Fattening Lambs
Keywords:
growth indices, lecithin, fattening lambsAbstract
Aim of this research was to determine the measure in which 100 g/head/day lecithin has an effect on the ruminal parameters and growth indices in lambs during the fattening process, compared to a normal ration which consisted of alfalfa hay and a concentrates mixture. Experiment was carried out on two experimental groups (n=10) of fattening Turcana lambs, from 138 to 176 days of age and an average weight of 28 kg. For the same level of feed consumption, lecithin improves the average daily gain by 14.85%, while the consumption rate for proteins and energy was 12.9% lower. Following lecithin administration the number of ruminal bacteria increasd to 4.52 x 108 cfu/ml ruminal fluid compared to the average of 3.68 x 107 cfu/ml for the control diet. Lecithin has as effect the reduction of the protozoa number by 168,944/ml ruminal fluid and the species are less diversified.
