Opis:: Meat and bone meal (MBM) can be a viable alternative to natural, organic and mineral fertilizers because it is rich in nitrogen (N), phosphorus (P), calcium (Ca), micronutrients and organic matter that can be recycled back into agricultural land. The aim of this study was to determine the optimal dose of MBM for winter oilseed rape (Brassica napus L.). Meat and bone meal was applied at three doses (1.0, 1.5 and 2.0 Mg ha-1) with the addition of mineral nitrogen at 79 and 40 kg N ha-1, and without the addition of mineral nitrogen (0 kg N ha-1), respectively. The effects exerted by MBM were compared with those exerted by mineral NPK fertilization (control treatment). Since MBM had low K content, K rate was 145 kg ha-1 in all treatments, and it was applied with mineral fertilizers. The macronutrient (N, P, K, Ca and Mg) content of winter oilseed rape seeds and straw, and macronutrient uptake by aboveground biomass were evaluated. A small-scale field experiment was conducted in northeastern Poland. The experiment had a randomized block design, and it was established on Dystric Cambisol developed from loamy sand. Changes in the uptake of the analyzed macronutrients and their concentrations in winter oilseed rape seeds and straw were affected by fertilization and weather conditions. Supplemental mineral N was applied before sowing to widen the narrow N/P ratio in MBM, which had a beneficial influence on the mineral composition and macronutrient uptake by the aboveground biomass of winter oilseed rape. Macronutrient (N, P, Ca and Mg) uptake by plants was highest in the treatment with the lowest MBM dose (1.0 Mg MBM ha-1) supplemented with 79 kg mineral N (50% N from mineral fertilizer and 50% N from MBM). The results of this study indicate that MBM applied at the dose of 1.0 t ha-1 meets the P and N requirements of winter oilseed rape in 100% and 50%, respectively. Therefore, the recommended mineral N fertilizer rate for winter oilseed rape can be reduced by 50%.

Opis:: The aim of the study was to present the results of comparative evaluation of the usefulness of PCR and microscopic methods for the detection of Processed Animal Protein (PAP) in feedingstuffs. In the validation study, the limit of the detection for PCR was determined on 0.05% for beef, 0.1% for pork and 0.2% for poultry meat and bone meal (MBM). Among 62 doubtful samples of feedingstuffs examined by microscopic method 41 (66.13%) were found as positive. Based on the results obtained with the use of the microscopic and PCR methods it is possible to state that the molecular biology methods can, at present, be used as a supplementary method in PAP detection.

Opis:: В двух опытах (1 и 2 ) поросят отнятых на 35-ый день жизни кормили до 91-го дня стандартной кормосмесью II (контрольные грурры) или кормосмесью модифицированной путем частичной или полной замены соевого шрота шротом семян конских бобов. В опыте I шрот конских бобов в количестве 4% массы кормосмеси подавали в естественной форме (II), а в количестве 8% после термической обработки (III) или экструзии (IV). В опыте 2 опытные кормосмеси содержали по 10% шрота конских бобов дополнительно высущенного в сушильне СБ - 1,5 (II) или шрота конских бобов в естественном виде подвергнутого процессу экструзии (III) без прибавки и с прибавкой лизина и метионина (дополнительно сущений шрот конских бобов- группа IV - L + М), естественный экстрагированный шрот конских бобов - группа V - L + М). В опыте 1 контрольные поросята (I) достигли веса 27,00 кг, опытные поросята групп II и III по 24,60 кг, а в группе IV 25,90 кг. Суточные аривесы составляли 334, 304, 302 и 320 г. В опыте 2 средний вес тела поросят групп I, II, III, IV и V, составлял соответственно 26,80, 24,80, 25,68, 25,40 и 25,90 кг, а суточные привесы соответственно 328, 289, 310, 303 и 313 г. В обоих опытах потребление овсяных единиц и переваримого общего белка на 1 грамм привеса образовалось в соответствии с количеством использoванных кормов. Частичная или полная замена соевого шрота шротом из конских бобов, сырых или подвергнутых термической обработке, в кормосмесях типа II приводила к существенному ухудшению продуктивных результатов поросят. Конские бобы подвергнутые экструзии не приводили к существенному снижению привесов поросят и использования корма.
The respective investigations comprised two experiments (1 and 2) with piglets divided into V groups, weaned on the 35th day of life and fet till the 91st day of life standard mixture P (control group) or diet partly or fully modified by substitution of soybean meal with field bean meal. In the experiment I the field bean meal in the amount of 4% of the mixture mass was given in natural form (II group) and in the amount of 8% of the mixture mass after thermal treatment (III group) or subjected to extrusion (IV group). In the 2nd experiment the mixtures under study contained by 10% of the meal of field bean additionally dried in the SB - 1.5 drier (II group or natural field bean subjected to the extrusion process (III group) without and with addition of lysine and methionine (additionally dried field bean - IV group, L + M, natural extruded field bean - V group, L + M). In the 1st experiment the control piglets (I group) reached the weight of 27.00 kg, in the II and III group by 24.60 kg and in the IV group 25.90 kg. Daily body weight gains amounted to 334, 304, 302 and 320 g, respectively. In the 2nd experiment the mean body weight of piglets of the I, II, III, IV and V group amounted to 26.80, 24.80, 25.68, 25.40 and 25.90 kg and daily weight gains to 328, 289, 310, 303 and 313 g. In both experiments conversion of oat units and total digestible protein per 1 kg of the body weight gain was in accordance with the amount of taken in fodder. Partial or full substitution in mixtures of the P type of soybean meal with meal of fouder bean, raw and subjected to thermal treatment, led to a significant worsening of the growth performance of piglets. Field bean subjected to extrusion exerted no significant on reduction of daily weight gains nor feed conversion.
