Исследования влияния системного применения гербицидов при ресурсосберегающей обработке почвы на качественные показатели зерна кукурузы проведены на землях ОАО «Агросоюз» Рузаевского района Республики Мордовия в 2014–2016 годах. Установлено, что обработка посевов гербицидом «Дублон» (1,2 л/га) и баковой смесью «Дублон Голд» (0,07 кг/га) + «Балерина» (0,25 л/га) способствовала повышению содержания сырого протеина в зерне до 93,67 и 94,97 г/кг соответственно. Анализ содержания жира в зерне кукурузы выявил, что наибольшим оно было в контрольном варианте. Внесение препаратов «Дублон», «Дублон Супер», «Дублон Голд» и их сочетаний с «Балериной» статистически достоверно снижало концентрацию жира. Используемые пестициды достоверного влияния на увеличение содержания крахмала в зерне кукурузы не оказывали. Содержание клетчатки снижалось: при использовании препаратов «Дублон Супер», «Дублон Голд» и «Дублон» + «Балерина» её уровень был ниже контроля на 5–10%. В результате увеличения урожайности зерна кукурузы за счёт высокой эффективности гербицидов во всех вариантах опыта возрастал сбор протеина с 0,51 до 0,75 т/га. В исследованиях также установлено, что в вариантах с применением баковых смесей гербицидов «Дублон + «Балерина» и «Дублон Голд» + «Балерина» по сравнению с контролем валовой сбор крахмала, сахара, сырого жира был наивысшим. Между содержанием в зерне кукурузы сырого протеина, клетчатки, сырого жира, сахара и крахмала наблюдалась достоверная слабая положительная зависимость. Гербициды группы «Дублон» повышали концентрацию сахара до 32,6–33,3 г/кг. В результате повышенного содержания жира в зерне кукурузы уровень валовой энергии был наивысшим в контрольном варианте — 19,37 МДж/кг. При внесении гербицидов она снижалась вследствие повышения доли белка в органическом веществе зерна кукурузы. The investigation was carried out at the OAO “Agrosoyuz” (the Ruzaevskiy district, Republic of Mordovia) in 2014–2016. The effect of herbicide application was tested on maize under minimum tillage. Plant treatment with “Dublon” (1.2 l ha-1) as well as the mixture of “Dublon Gold” (0.07 kg ha-1) and “Balerina” (0.25 l ha-1) increased crude protein in grain up to 93.67 and 94.97 g/kg, respectively. The highest fat content was observed in the control. Application of “Dublon”, “Dublon Super”, “Dublon Gold” and their mixtures with “Balerina” significantly reduced fat accumulation. The preparations had no significant impact on starch formation. “Dublon Super”, “Dublon Gold” and “Dublon” + “Balerina” reduced fiber content by 5–10%. As a result of herbicide use grain productivity increased, and protein yield raised from 0.51 to 0.75 l ha-1. Mixtures of “Dublon” + “Balerina” as well as “Dublon Gold” + “Balerina” provided the highest gross yields of starch, sugar, and crude fat. Significant positive correlation was observed among crude protein, fiber, fat, sugars and starch. The “Dublon” herbicides positively affected sugar concentration up to 32.6–33.3 g/kg. Due to higher fat content gross energy yield was the highest in the control — 19.37 MJ/kg. Herbicide treatment reduced gross energy due to the higher protein content in grain organic matter.

The quality and hygienic status of milk are of importance for both dairy industries and consumers. In the present study, the effect of season on the quality and microbial properties of sheep milk and yoghurt produced from sheep milk were surveyed. In total, 30 sheep-milk samples were collected from January to August 2011, and yoghurt was produced from these samples. The fat content, titratable acidity and pH showed changes across the year. Seasonal variation was found to have a significant (P < 0.05) effect on nitrogen components, particularly crude protein, non-casein protein and non-protein nitrogen contents, fat content, pH and titratable acidity. Sensory analysis showed that the quality of yoghurt samples produced in winter was higher than that of yoghurt produced in summer (P < 0.05). This work showed the effect of season on chemical and sensory properties of sheep milk and yoghurt in Qazvin, Iran.

Abstract Increasing the amount of liquid fat to the ration during extrusion can negatively affect product density and product expansion. Ingredients, like whole soybeans (WSB), which are high in fat may aid increased energy density while avoiding production issues. In a preliminary extrusion project, the effects on the process of foods were evaluated, followed by animal evaluation. The objective of this study was to determine the effect of dehulled WSB on nutrient digestibility and stool quality by dogs. Experimental diets were extruded with 0%, 10%, 20%, and 30% WSB (WSB0, WSB10, WSB20, and WSB30, respectively). Seven castrated male and three spayed female Beagles of similar age (6.25 ± 0.452 years) were individually housed and fed the experimental diets. The study was designed as replicated 4 × 4 Latin square where dogs were allowed 9-d adaptation followed by 5-d total fecal collection for each period. Titanium dioxide was added to all diets (0.4%) to serve as an indigestible dietary marker to determine apparent total tract digestibility (ATTD). Least-square means of fecal parameters and ATTD were analyzed with a single degree of freedom contrasts and significance at α = 0.05. There was no difference among treatments for food intake or fecal scores. However, there were linear increases (P &lt; 0.05) in DM fecal output, as is fecal output, fecal moisture, and defecation frequency stools/day as WSB increased in the diets. Apparent total tract digestibility of dry matter, crude protein, acid hydrolyzed ether extract, and gross energy decreased linearly as dogs were fed increasing levels of WSB in the diets (P &lt; 0.05). In conclusion, additional thermal processing before extrusion may improve nutrient digestibility, although stool quality was not affected by the inclusion of WSB.

Научные исследования выполнены в 2017–2019 годах на опытном поле ФГБНУ «ФАНЦ Северо-Востока». Почва опытного участка дерново-подзолистая, среднесуглинистая, сильнокислая, с содержанием в пахотном слое 1,9% гумуса, средним — подвижного фосфора и обменного калия, подвижного алюминия — от 4,23 до 5,24 мг/кг почвы. В статье изложены результаты исследования влияния минеральных удобрений, в том числе фосфоритной муки, а также известкования на продуктивность и качество кормовой массы лядвенце-тимофеечной травосмеси. Цель работы — определить наиболее эффективные виды минеральных удобрений, в том числе на известкованном фоне, для получения высокой продуктивности и качества кормовой массы. Установлено, что высокая продуктивность лядвенце-тимофеечной травосмеси получена при совместном внесении минеральных удобрений и извести. Сбор сухого вещества составлял более 5,0 т/га, что достоверно выше контрольного варианта в среднем за 3 года жизни трав на 39,9% при внесении фосфорно-калийных удобрений и на 43,8% — при добавлении азотных. Выход обменной энергии в этих вариантах превышал 50 ГДж/га, сбор сырого протеина был более 0,60 т/га. Известкование достоверно увеличивало сбор сухого вещества трав на 19,0%. Фосфоритование не обеспечивало достоверной прибавки сбора сухого вещества. Внесение азотных удобрений (N30) совместно с фосфорно-калийными, как и калийных (К60) с фосфоритной мукой, не приводило к достоверному росту сбора сухого вещества. Содержание сырого протеина зависело от доли лядвенца в урожае. При высоком преобладании лядвенца во втором укосе во второй и третий годы жизни трав содержание сырого протеина превышало 17%. The investigation took place in 2017–2019. Soil — sod-podzolic with medium clay content, low pH, and medium concentrations of soluble phosphorus and exchange potassium. Humus content — 1.9%, soluble aluminium — 4.23 –5.24 mg/kg. The article focuses on the effect of mineral fertilizers and liming on productivity and forage quality of birdʼs-foot trefoil mixed with common timothy. The experiment aimed at identification of the most effective mineral fertilizers leading to high yield and quality of forage mass. Fertilization resulted in high yield of the mixture on the background of liming. Dry matter yield (DM) reached 5.0 t ha-1, significantly exceeding the control by 39.9% under PK fertilization and by 43.8% — when applying NPK. Exchange energy yield exceeded 50 GJ ha-1, crude protein — 0.60 t ha-1. Liming significantly increased DM content by 19.0%. Phosphorite meal had insignificant effect on DM increase. Application of nitrogen fertilizers (N30) in combination with PK as well as К60 with phosphorite meal showed no significant influence. Accumulation of crude protein depended on birdʼs-foot trefoil ratio in the yield. Crude protein exceeded 17% in the second cut due to the high proportion of birdʼs-foot trefoil in the second and third life cycles.

This research aimed at generating and evaluating prediction equations to estimate metabolizable energy values in poultry offal meal. The used information refers to values of apparent and true metabolizable energy corrected for nitrogen balance (AMEn and TMEn) and for chemical composition of poultry offal meal. The literature review only included published papers on poultry offal meal developed in Brazil, and that had AMEn and TMEn values obtained by the total excreta collection method from growing broiler chickens and the chemical composition in crude protein (CP), ether extract (EE), mineral matter (MM), gross energy (GE), calcium (Ca) and phosphorus (P). The general equation obtained to estimate AMEn values of poultry offal meal was: AMEn = -2315.69 + 31.4439(CP) + 29.7697(MM) + 0.7689(GE) - 49.3611(Ca), R² = 72%. For meals with high fat contents (higher than 15%) and low mineral matter contents (lower than 10%), it is suggest the use of the equation AMEn = + 3245.07 + 46.8428(EE), R² = 76%, and for meals with high mineral matter content (higher than 10%), it is suggest the equations AMEn = 4059.15 - 440.397(P), R² = 82%. To estimate values of TMEn, it is suggested for meals with high mineral matter content the equation: TMEn = 5092.57 - 115.647(MM), R² = 78%, and for those with low contents of this component, the option is the equation: TMEn = 3617.83 - 15.7988(CP) - 18.2323(EE) - 96.3884(MM) + 0.4874(GE), R² = 76%.
