In a trial with lactating sows, examined the effects of using a meal with different levels ofprotein and energy. In an experiment involving 240 sows and gilts last 30 days before farrowing, allanimals involved in the experiment were divided into two groups of 120 sows in the group, and by 60 insubgroups. Sows in the experiment were 65 days, and during the last 30 days of pregnancy and lactationand the experiment ended with with the weaning of piglets. The sows were fed diets during lactation.Results were as follows. Sows that were fed into the model food diet with 15% protein and 12 MJ ME / kgof diet, had a protein content of 21.00% round muscles. Consuming foods sows in the model diet with15% protein and 14 MJ ME / kg diet, there was an increase in the protein content of ham muscle to21.75%. In sows that were fed into the model food diet with 19% protein and 12 MJ ME / kg diet, theprotein content in the ham muscles was 22.24%. Dietary feeding of sows with a model of 19% protein and14 MJ ME / kg diet, there is a change in the protein content of ham muscles, and then it was 22.72%.
