Abstract. Title of the paper: The composition of the Colostrum of some beef cattle breeds according to time of post partum. This research was carried out to investigate the changes of main components of Colostrum with 0–4 days after calving by five beef cattle breds, kept in Hungary. After calving and 24 hours later beef cattle breeds had higher dry matter content in Colostrum compared to that of dairy breeds; but the dairy breeds were superior to the beef cattle breeds from the second day. This relates to the Colostrum of the beef cattle breeds more concentrated than the dairy breeds during the first 24 hours but they reached that values eariier which were characteristic to the normal milk. Examining the protein content of Colostrum there were similar tendencies in change of dry matter content with difference that the protein content of Colostrum of beef cattle breeds was higher than that of the dairy breeds between the 2nd and 4th days, too. On the first and the second days the fat content of Colostrum of the sucklers decreased which was related to the higher dilution in beef cattle breeds. The sugar content of Colostrum of the beef cattle breeds has increased between the calving and the 4th day post partum, and reached the values characteristic to the normal milk – (4.8–5.0%) – on the 5th–6th day. There was not significant difference between the beef and the dairy breeds, neither in sugar nor in the ash content. The ash content of Colostrum reached the values characteristic to the normal milk, 7–8 days after calving. The whey protein and the non protein nitrogen content of Colostrum of the beef cattle breeds were higher than that ofthe dairy breeds, significantly. Decreasing of these fractions in the beef cattle breeds were more moderate than the dairy breeds as in case of the total protein content, according to time. Our calculations show that whey protein content of the beef cattle breeds reached that values which were characteristic to the normal milk, after the 5th day post partum. Not having found a decided difference in the casein content of Colostrum between the beef and the dairy breeds. The casein content of Colostrum of blonde d' Aquitaine and Limousin higher than that ofthe other kind of beef cattle breeds, which manifests itself in the ratio of whey protein and casein, too. At the same time the ratio of whey protein and casein in both Angus types differ from the other beef cattle breeds in favour of the whey protein. The calculated immunglobulüj-G values of Colostrum milked immediately after calving were usually much higher at sucklers than at the dairy breeds. This was true especially beUveen the 1st and the 4th days which was connected with the more moderate decrease of IgG fraction in the beef cattle breeds. Similarly the data of the literature the IgG content ofthe fresh milked Colostrum was determined primarily by the breed. According to our examinations this determination becomes more unimportant moving off the time of calving. The energy content of Colostrum at Black Angus and Red Angus rose among the other kind of beef cattle breeds. The average energy content ofthe Colostrum of blonde d' Aquitaine and Limousin was connected with the high protein content of their Colostrum. The energy content of Colostrum of Hungarian Simmental was the lowest.

The dry matter and moisture contents of the aboveground vegetative organs and kernels of four maize hybrids were studied in Martonvásár at five harvest dates, with four replications per hybrid. The dry matter yield per hectare of the kernels and other plant organs were investigated in order to obtain data on the optimum date of harvest for the purposes of biogas and silage production.It was found that the dry mass of the aboveground vegetative organs, both individually and in total, did not increase after silking. During the last third of the ripening period, however, a significant reduction in the dry matter content was sometimes observed as a function of the length of the vegetation period. The data suggest that, with the exception of extreme weather conditions or an extremely long vegetation period, the maximum dry matter yield could be expected to range from 22–42%, depending on the vegetation period of the variety. The harvest date should be chosen to give a kernel moisture content of above 35% for biogas production and below 35% for silage production. In this phenophase most varieties mature when the stalks are still green, so it is unlikely that transport costs can be reduced by waiting for the vegetative mass to dry.

Цель исследований – дать оценку сохраняемости и болезнеустойчивости современных сортов и гибридов моркови столовой и определить корреляционные зависимости влияния биохимических показателей качества на сохраняемость и степень поражения моркови столовой различными видами болезней в процессе хранения. Исследования проводились в 2011–2016 годах во ВНИИО – филиале ФГБНУ ФНЦО по общепринятым методикам. В биохимической лаборатории отдела земледелия и агрохимии содержание сухого вещества определяли высушиванием до абсолютно сухого веса, общего сахара – по Бертрану, аскорбиновой кислоты – по Мурри, нитраты – ионоселективным методом. При характеристике моркови столовой важнейший показатель, определяющий его качество – количество сухого вещества и сахаров. В процессе хранения были выявлены следующие болезни моркови: серая гниль (Botrytis cinerea Pers. ex Fr.), белая гниль (Sclerotinia sclerotiorum (Lib.)), белая парша (Rhizoctonia carotae Rad.), альтернариоз (Alternaria radicina M., Dr. et E.). В большей степени сортообразцы моркови столовой поражались серой гнилью. Лучшими по сохраняемости сортообразцами были Корсар (94,6%), F1Берлин (94,5%), Берликум Роял (94,1%) и F1 Звезда (94%). Сохраняемость у зарубежных сортов и гибридов моркови столовой была немного выше, чем у отечественных (на 0,4%) как за счет меньшей величины убыли массы (6,3% против 6,4%), так и потерь от болезней (1,6% против 1,9%). Сохраняемость корнеплодов моркови находится в прямой корреляционной зависимости от содержания сухого вещества (r=+0,41), каротиноидов (r=+0,39), моносахаров (r­=+0,30) и суммы сахаров (r=+0,27). Проявление серой гнили находится в обратной корреляционной связи с содержанием сухого вещества и каротиноидов (r=-0,37 и r=-0,35 соответственно), белой парши – в прямой корреляции с содержанием сухого вещества , моносахаров и дисахаров (r= +0,21; r= +0,39; r= -0,41 соответственно), белой гнили в обратной корреляционной связи с содержанием сухого вещества, моносахаров и дисахаров. The purpose of the research is to assess the persistence and disease resistance of modern varieties and hybrids of carrots and to determine the correlation between the influence of biochemical quality indicators on the persistence and degree of damage to carrots by various types of diseases during storage. The research was conducted in 2011–2016 at ARRIVG – branch of FSBSI FSVC, according to generally accepted methods. In the biochemical laboratory of the Department of Agriculture and Agrochemistry, the dry matter content was determined by drying to absolutely dry weight, total sugar – by Bertran, ascorbic acid – by Murri, nitrates – by the ion-selective method. When describing carrots, the most important indicator that determines its quality is the amount of dry matter and sugars. During storage, the following diseases of carrots were detected: gray rot (Botrytis cinerea Pers. ex Fr.), white rot (Sclerotinia sclerotiorum (Lib.), white scab (Rhizoctonia carotae Rad.), alternariasis (Alternaria radicina M., Dr. et E.). To a greater extent, varieties of table carrots were affected by gray rot. The best preserved varieties were Corsar (94.6%), F1 Berlin (94.5%), Berlicum Royal (94.1%) and F1 Zvezda (94%). The persistence of foreign varieties and hybrids of table carrots was slightly higher than that of domestic ones by 0.4%. both due to a smaller amount of weight loss (6.3% vs. 6.4%) and losses from diseases (1.6% vs. 1.9%). The persistence of carrot root crops is directly correlated with the content of dry matter (r=+0.41), carotenoids (r=+0.39), monosaccharides (r=+0.30) and the amount of sugars (r=+0.27). The manifestation of gray rot is in inverse correlation with the content of dry matter and carotenoids (r=-0.37 and r=-0.35, respectively), white scab is in direct correlation with the content of dry matter (r= +0.21; r= +0.39; r= –0.41, respectively), white rot is in inverse correlation with the content of dry matter, monosaccharides and disaccharides.
