Ninety six large white pigs of 30 kg body mass were divided into 6 groups and 4 pigs per pen. All pigs were fed commercial grower mixture up to about 70 kg body mass. Further feeding to about 110 kg was differencial by applying commercial finishing mixture (groups I, II and III) or such mixture with reduced by 22% protein level (groups IV, V and VI) . Energy level in these mixtures was increased by 29% (fat supplement, groups III and VI ), or decreased by 20% (straw meal supplement, groups II and V ) . At the end of experiment carcass quality was evaluated. During growing period body weight gain was similar for all groups. During finishing period decrease of energy caused lower gains on both protein levels. Increase of energy lead to higher gains on normal protein level and slightly lower gains on lower protein level. At normal protein level decrease of energy in feeds did not change carcass fat content,increase of energy increased fat content. At low protein level pigs fed low energy diet had carcassess of lower quality.

The experiments were made on 180 weaners in order to utilize in the pig fattening large proportions of dehydrated forages obtained from whole maize plants, alfalfa and sugar beets, and to determine to what extent these feeds may replace the cereals. The fattening pigs were divided into three different nutritional groups: I - control, II - with ground grain as basic feed and III - with sugar beet meal as basic feed. Each of these groups consisted of two subgroups: the subgroup L received the alfalfa meal, while the subgroup K was fed with the maize meal. The further division was made by use of different meal levels which were in the first group initially 5% and 7% in the second period. In the second and third group the meal levels uere 10, 20 and 25%. The meal quantity was increased by 5% in the second period. The protein concentrate "Prowit" was used as the protein feed. The digestibility and nitrogen balance of the used mixed feed have been determined. The fattening results for the groups receiving ground grain (second group) or sugar beet meal (third group) and large quantities of alfalfa or maize meal were very unfavourable. The growth rate significantly decreased and the feed efficiency was lower. No considerable changes in growth rate were observed during second fattening period. The feeding of fattening pigs on mixed feed containing sugar beet meal large quantities of alfalfa or maize meal enabled to save 71.8% of ground grain, however, the consumption of protein concentrate increased by 69%. As the meal proportion in the mixed feed increased, the quantity of ground grain decreased from 6.2 up to 14.5%. The maize meal - when compared to the alfalfa meal - enabled to save the ground grain consumption by 7.3%, however, the protein concentrate consumption increased by 23%. The meal obtained from whole maize plants has lower protein content than the alfalfa meal and should not be used for fattening pigs, since slightly better results were obtained only owing to much larger quantities of protein concentrate given to fattening pigs. The sugar beet meal has improved the carcass conformation and nitrogen retention. The mixed feeds containing quantities of alfalfa or maize meal have not improved the carcass quality.
