The diploma thesis is aimed on verification of a posibility of using blue lupin as a proteinic fodder in pig fattening and is based on a two-phase experiment that corresponds with two-phase fattening. In the first (from 22 to 41 kg) and second (from 41 to 119 kg) phase, the control group was fed with a mixture based on extracted soybean meal, the treatment group was fed with a mix containing 10 % (first phase) and 13 % (second phase) of blue lupin. The observed statistical indicators were average daily gain in weight, average daily fodder consumption and average nutrients conversion. The first phase of the experiment resulted in growth of all of the observed indicators. The treatment group showed a nutrients conversion increased by 150 g and average daily gain in weight increased by 200 g in comparison with the control group. In the second phase of the experiment (during first 31 days), the observed indicators of the treatment group showed a drop (additional 350 g of mixture were needed for 1 kg gain in weight compared to the control group, the average daily gain was lower by 130 g). Subsequently a gradual stabilization followed, resulting in a final difference of 160 g in nutritions conversion and 50 g of average daily gain in favor of the control group. The economical effect of 34.5 CZK per fattened pig was found despite of worse indicator values in the second phase. Blue lupin has potential to be used as a substitute for soybean, but only when assuming self-sufficiency, because its availability is relatively low when compared to soybean.

The aim of this thesis was to compare the effects of feed mixtures with different share of selected plant components on common carp (Cyprinus carpio L.). Two feed tests were conducted in recirculation aquaculture system, in tanks with a volume of 160 l. The tests were conducted in two repetitions and lasted for 64 - 65 days. The feed ratio was 2% of the fish stock weight. For the first test 6 feed variants were prepared. A complete feed mixture for carp (KP1 Plus 15%) was chosen for the control and also as the base for other experimental feed mixtures. The following variants were prepared: feed mixtures with the addition of pea 15%, soybean 15%, lupine 15%, 30% and 45%. The resulting effect was similar for all feeds. Soybean 15% feed achieved the best results (FCR 2.47, SGR 0,71 %.d-1, RGR 50,14 %). Lupine feeds showed worse production parameter levels, whencompared tothe control. From an economic point of view, the mostcost effectivefeed was lupine 45% (FCR 2,67, SGR 0,66 %.d-1 RGR 46,64 %). For the second test 4 feed variants were prepared. The control and base for experimental feed mixtures was the same as in the first test (KP1 Plus 15%). The following feed variants were used: lupine 20%, 45% and 70%. Feed variant with 45% lupine achieved the best results (FCR 2,23, SGR 0,79 % .d-1, RGR 56,75 %) ,followed by lupine 70% (FCR 2,24, SGR 0,78 %. d-1, RGR 56,91 %), therefore, lupine feeds have achieved better production and economic parameters, when compared to the control.

It has been proven that white lupine seeds (WLS) is a suitable crude protein (CP) source for growing-fattening rabbits, as well as for the lactating rabbit does. There are no reports, however, in the literature regarding the effect of blue lupine seeds (BLS) on rabbit doe milk production and composition as well as the growth of their litters. Therefore, the aim of this diploma thesis was to evaluate the effect of lactation and weaning diets based on BLS (Lupinus angustifolius cv Probor) on milk yield and milk composition of the rabbit does, as well as on growth performance and carcass quality of their progeny. Two lactation diets (LLB and LLU, having identical DP/DE ratio) and two weaning diets (VLB and VLU, having identical DP/DE ratio) were formulated. The LLB diet (control) contained WLS (25.0%) as the main CP sources, whereas the LLU diet was based on BLS (28.5%). As a result, the LLB diet had slightly greater ether extract content than did the LLU diet. The VLB diet (control) included WLS (12.0%) as the main CP source, whereas the VLU diet was based on BLS (15.0%). No additional fat was added to any of the diets. A total of 32 Hyplus rabbit does (16 animals per treatment; at the 3rd parturition) were fed 1 of the 2 lactation diets during the entire lactation (35 days). Does were housed in modified cages which allowed controlled suckling (once a day at 7 am) and separate access of does and their litters to feed. Feed intake and milk yield were measured daily during the entire lactation period, whereas litter weight was measured every 7 d. Milk yield was measured by weighing the rabbit does immediately before and after suckling. Five does of each group were used to evaluate milk composition. Milk was collected manually at d 21 of lactation. The litters were standardized to 9 kits on the day of birth. Litters were offered weaning diets with the same CP source as in the lactation diet of their mothers from d 17 to 80 of age. At d 37 of age (weaning), 99 rabbits on each weaning diet were used to evaluate growth performance and health. Feed intake, feed efficiency and milk production of does (on average 263 g/d) were not affected by dietary treatments, as well as milk efficiency (on average 0.59) and the growth of their litters (on average 30.4 g/d per rabbit). Live weight at weaning (P=0.005), milk dry matter (P=0.028) and fat contents (P=0.016), as well as fat output per kg of metabolic weight (P<0.001) were higher in does fed the WLS diet. After weaning, final live weight (by 168 g; P=0.061), average daily weight gain (by 3 g/d; P=0,024) and carcass weights were lower in rabbits fed the diet based on BLS than in those fed with the WLS diet. The number of ill + dead rabbits caused by digestive disease was lower (23 rabbits vs. 38 rabbits; P=0.042) in rabbits fed the diet based on WLS. The results of the diploma thesis confirmed that WLS is a suitable CP source for the rabbit diets. Negative findings such as a higher mobilisation of body reserves of does in the later phase of lactation, as well as the lower final live weight and the higher sanitary risk index of rabbits fed the diets based on blue lupine seeds suggest difference between lupine species in terms of feed efficiency. These findings should be elucidated and confirmed by the comparing with other blue lupine varieties.

The diploma thesis deals with the development of the market for protein crops. The literature research deals one hand with the distribution and morphology of legumes, and on second hand with the structure and chemical composition of seeds of selected species (pea, soybean and lupine). The literature research also covers the production of protein concentrates and their commercialization. The practical part is mainly engaged in the analysis of market developments of selected species of legumes in the Czech Republic, especially during the years 2000 - 2015, in comparison with the market development of the individual European states (Germany, Austria, Poland, Slovakia and France). The outcome of this diploma thesis is the ordination of statistical data available in clear graphical and tabular outputs, it does not miss time series evaluation of development of individual crops in both the Czech Republic and other selected countries.
