Testing of compound feeds containing different level of lysine in feeding fattening pigs
2006
Petrov, P.
The experiments comprised 60 fattening pigs of the Danube White breed. The animals were equally divided into three groups of 10 (6 castrated males and 4 females).The experiments began after weaning the pigs at 8 kg live weight and finished after reaching 110 kg live weight. The animals from the control and experimental groups, during the three sub-periods, were given compound feeds with equal level of metabolizable energy, protein, methionine+cystine, tryptophane and threonine, but with different lysine level.The lysine content in the compound feeds for group II and III during the first sub-period was increased by 0.2% and 0.4% compared to group I.The higher lysine content in the compound feeds at equal level of metabolizable energy and protein showed a trend for gain increase by 2.15 ands 2.94%.
