<description>Эффективность применения пробиотиков при консервировании зернофуража повышенной влажности
ФЕДАК, Наталья; ЧУМАЧЕНКО, Сергей; ДАРМОГРАЙ, Любомир; КРАВЧЕНКО, Наталья
Эффективное сохранение зернофуража повышенной влажности является важной проблемой кормопроизводства, особенно в Карпатском регионе Украины, климатические условия которого отличаются чрезмерной увлажненностью. Существующие способы хранения влажного зерна экономически не оправданы из-за высокой стоимости энергоносителей. Задачей исследований было усовершенствование процессов консервирования зернофуража повышенной влажности при использовании недорогих эффективных препаратов, изготовленных на основании новых штаммов микроорганизмов пробиотиков с целью максимального сохранения питательных веществ зерна. В данных исследованиях использовали новые микробиологические препараты Субтикон и KT-L 18/1 в качестве консервантов зерна озимой пшеницы (влажностью 19,7 %) и озимого ячменя (влажностью 19,2 %). Два варианта: без обработки и с обработкой углеаммонийной солью служили контролем. Через 15, 30 и 70 суток хранения определяли химический состав консервированного зерна, степень сохранности сухого вещества, содержание и соотношение основных кислот брожения и количественный состав микрофлоры: молочнокислых бактерий, грибов и дрожжей, аэробных бацилл, псевдомонад. Через 70 суток хранения в вариантах, обработанных препаратами Субтикон и КТ-L 18/1, cохранность сухого вещества как интегрального показателя питательности составила: 98,1 и 97,5 % (пшеница) и 99,0 и 98,3 % (ячмень). Исследование микробиологических показателей и содержания основных кислот брожения подтвердило консервирующую способность отмеченных препаратов. В зернофураже, обработанном пробиотиками, численность наиболее желательных молочнокислых бактерий была выше чем в контрольных вариантах. Наибольшая концентрация молочной кислоты, которая является продуктом жизнедеятельности молочнокислых бактерий и основным консервирующим фактором, была в варианте с консервантом KT-L 18/1.; The effective conservation of grain fodder with high humidity is an important problem of feed production, especially in the conditions of Carpathian region of Ukraine with damp climate. Known methods for wet grain storage are economically unjustified due to the high cost of energy. The aim of the research was to improve the processes of preservation of grain fodder with high humidity by using inexpensive preparations made of new probiotic microorganisms strains for maximum preservation of nutrients in grain. In this study the new microbial preparations Subtikon and KT-L 18/1 were used as preservatives for grain of winter wheat (19.7 percent moisture) and barley (19.2% percent moisture). Two variants: a) no treatment and b) carbon-ammonium salt treatment served as controls. After 15, 30 and 70 days of storage the chemical composition and the degree of preservabilty of dry matter were determined, as well as the content and ratio of major fermentation acids and quantitative composition of microflora: lactic acid bacteria, fungi, yeasts, aerobic bacilli, pseudomonads, and clostridia. After 70 days of storage in the experimental variants treated with Subtikon and KT-L 18/1 the preservabillity of dry matter as an integral indicator of fodder nutritive value was of 98.1 and 97.5% (wheat) and 99.0 and 98.3% (barley). The analysis of microbiological parameters and major fermentation acids content confirmed the preserving ability of the analyzed preparations. In the grain treated with probiotics the number of most desirable lactic acid bacteria was higher than in the control variants. The highest concentration of lactic acid which is the product of lactic acid bacteria activity and the main preservating factor was found in KT-L 18/1 variant.

<description>Генетическая структура коров черно-пестрой породы по лактопротеинам
ЛУПОЛОВ, Татьяна; ГАНДЖА, Алла; КУЛЕШЕВИЧ, Янина
Систематический генетический мониторинг в популяциях позволяет контролировать уровень генетического разнообразия, использовать возможности маркерной селекции, включая оценку внутрипородной дифференциации, формирование оптимальной генеалогической структуры и селекцию на гетерозис. В статье приводится информация о генетической структуре популяций белорусских черно-пестрых коров в локусах лактопротеинов CSN3, LALBA, BLG. В двух хозяйствах, в локусах LALBA, BLG наиболее часто встречаемым – от 42% до 51% является гетерозиготный генотип АВ. В локусе CSN3 преимуществом обладали гомозиготы АА (65 % – 72 %). Аллели имели практически равную частоту – 61 % и 62 % для LALBAA и 39 % – 38 % для LALBAB. Частоты CSN3А и CSN3В имели практически одинаковые значения – 0,806 – 0,853 и 0,194 – 0,147 соответственно. В генетически равновесных (χ2&lt;3,84) популяциях коров, встречаемость аллеля BLGA составила – 0,549 и 0,486, BLGB – 0,451 и 0,514. Средняя гетерозиготность определена на уровне 39,6 % – 43,4 %; Systematic genetic monitoring in populations allows to control the level of genetic diversity, to use the capabilities of marker selection, including the assessment of intra-breed differentiation, the formation of an optimal genealogical structure and selection for heterosis. The article provides information about the genetic structure of the populations of Belarusian Black-and-White cows at the lactoprotein loci CSN3, LALBA, BLG. In two farms at the LALBA, BLG loci, the most frequently encountered (from 42% to 51%) is the heterozygous genotype AB. At the CSN3 locus AA homozygotes were predominant (65% – 72%). Alleles had an almost equal frequency – 61% and 62% for LALBAA and 39% – 38% for LALBAB. The frequencies CSN3A and CSN3B had almost the same values – 0.806 – 0.853 and 0.194 – 0.147, respectively. In genetically equilibrium (χ2 &lt;3.84) cow populations, the occurrence of the BLGA allele was 0.549 and 0.486, BLGB – 0.451 and 0.514. The average heterozygosity is determined at the level of 39.6% – 43.4%.

<description>Modificările morfologice în fascioloza ovinelor
NAFORNIȚA, Nicolae
Studiul s-a realizat în perioada decembie 2017–mai 2019. Examenului necropsic au fost supuse10 cadavre de oi, cu vârstă cuprinsă între 12 luni și 5 ani, din rasele Țigaie și Țurcană. Șapte dintre ovinele necropsiate au prezentat leziuni la nivelul ficatului, exprimate prin hepatită difuză și hepatită fibroasă interstițială (fibrozare, sclerozare, pseudociroză). La secționarea și examinarea parenchimului hepatic s-a constatat prezența formelor parazitare de Fasciola hepatica într-un număr foarte mare. Modificările parenchimului hepatic sunt complexe atât din punct de vedere morfopatologic și histologic, cât și după suprafața de extindere, fiind exprimate prin modificări circulatorii, distrofii, hipertrofii și procese inflamatorii de tip eozinofilic sau limfohistiocitar, cu derularea unor procese severe de fibrozare, mai cu seamă în cazul unor invazii repetate. Chiar și după efectuarea unor tratamente antiparazitare, ovinele infestate repetat sfârșesc murind, având în vedere modificările severe de ordin morfologic ale ficatului. Din aceste considerente, fascioloza este una dintre cele mai grave boli pentru această specie de animale.; The study was conducted between December 2017 and May 2019. Ten sheep bodies aged between 12 months and 5 years, from the Tsigai and Turcana breeds were subjected to necropsy examination. Seven of the sheep’s bodies presented at the necropsy exam showed liver injury, expressed by diffuse hepatitis and interstitial fibrous hepatitis (fibrosis, sclerosis, pseudocirrosis). At the necropsy examination, along with the hepatic lesions we highlighted the presence of F. hepatica in a very high number. The changes of the hepatic parenchyma are complex both from the morphopathological and histological point of view, as well from the standpoint of the extension surface, being expressed by circulatory changes, dystrophies, hypertrophies and inflammatory processes of eosinophilic or lymphohistiocitary type, with the development of severe fibrosis processes, especially in the case of repeated reinvasions. Repeatedly infested sheep, even when performing repeated antiparasitic treatments, end in death due to severe morphological changes in the liver. For these reasons, the fasciolosis is one of the most serious for this species of animals.
