Intensive hog production is expanding into semi-arid regions of Alberta, where perennial forage lands are increasingly targeted for manure applicati on despite limited guidelines for its efficient use. Herbage yield and crude protein were assessed over two consecutive years within two native rangelands and two tame pastures, following different rates (10, 20, 40, 80 and 160 kg ha-1 NH4-N), methods (surface banding vs. subsurface injection) and seasons (fall vs. spring) of one-time liquid hog manure (LHM) application. Increasing manure rates improved grass yield across all sites the first growing season after treatment, from 1626 to 3576 kg ha-1. Although absolute increases in production were greatest on tame pasture, relative yield increases were similar among sites. Average crude protein (CP) concentration also increased from 69 to 91 g kg-1 in the first year. Despite low rainfall and the absence of a yield response in the second year, grass CP and crude protein yield (CPY) were maximized with increased manure application, highlighting the positive effects of manure on forage production, even with drought. Forb yields demonstrated variable effects among sites, with increasing manure decreasing alfalfa and increasing native forbs. Overall, both semi-arid tame pastures and native rangelands responded positively to LHM application, highlighting the complementary nature of hog and forage production under these conditions.

Significant Difference

This study investigated the influence of treated greywater on growth and protein content of multipurpose (forage and ornamental) transplants, Prosopis juliflora L., Prosopis tamarugo L., and Albizia lebbeck L. Transplants of tested species were irrigated with treated greywater, diluted greywater (grey + distilled water, 1:1/by volume), and distilled water (control) for seven months. Water quality analysis showed that the concentrations of nutrients and heavy metals found in the greywater were within the acceptable range compared with Jordan Institution for Standard and Metrology (JISM) and the World Health Organization (WHO) thresholds for safe use of greywater. Escherichia coli found in the greywater were lower compared to JISM and WHO guidelines for the safe use of greywater. Irrigation with treated greywater increased shoot fresh weight by 24–39% and dry weight by 34–40% compared to diluted greywater and control. No significant difference in crude protein was noticed between water treatments. Prosopis species (P. juliflora Albizia lebbeck L. and P. tamarugo Albizia lebbeck L.) had higher shoot fresh (35%) and dry weight the same species had lower crude protein (44%) when compared to Albizia lebbeck Albizia lebbeck L. The reuse of treated greywater for landscaping or forage production alleviates the demand for water resources and reduces the pressure on wastewater treatment plants. However, considering the controversial findings of previous studies on greywater quality (especially, long-term reuse), the reuse of treated greywater needs to be considered with caution and periodic quality analyses and economic assessments are required.

По результатам научных исследований, выполненных за ряд лет в растениеводстве и животноводстве, показана целесообразность интродукции в кормопроизводство Пермского края новой многолетней бобовой культуры эспарцета песчаного. По четырёхлетним наблюдениям (2012 2015 годы) в полевых опытах культура не уступала по урожайности кормовой массы традиционному для региона клеверу луговому, а по концентрации обменной энергии и сырого протеина в сухом веществе была на уровне клевера лугового и люцерны изменчивой, но в разы превосходила их по содержанию сахара. Сенаж это единственный вид зимнего корма, максимально сохраняющий обменную энергию, протеин, сахар, каротин, достаточно концентрированный, чтобы обеспечивать потребности высокопродуктивных животных. В 2018 году на Лобановском молочном комплексе ООО Русь в Пермском районе Пермского края были проведены научнохозяйственный и физиологический опыты по скармливанию сенажа из эспарцета песчаного голштинизированным коровам чёрнопёстрой породы. При использовании сенажа из эспарцета песчаного животные в сутки потребляли сухого вещества на 2,3 3,9 кг на голову больше по сравнению с группой, где в рационе было сено (контроль). В результате использования сенажа из эспарцета песчаного переваримость сухого вещества рациона у опытных групп животных была выше на 2,55 5,80 по сравнению с контрольной органического вещества на 2,54 4,14 . За учётный период научнохозяйственного опыта (120 дней) от коров опытных групп получено по 399327,2 и 414431,9 кг молока, что со средней степенью достоверности выше продуктивности животных контрольной группы (391045,4). По содержанию молочного жира и молочного белка преимущество достоверно также было за опытными группами. Затраты корма на 1 кг молока составили в контроле 0,74 энергетических корм. ед. (ЭКЕ), в опытных группах 0,71 и 0,69 ЭКЕ. Hungarian sainfoin was shown to be an effective perennial legume crop in the forage production of the Perm Territory. For 4 years (2012 2015) this crop produced forage mass, exchange energy and crude protein comparable to the ones of red clover and bastard alfalfa but exceeded them significantly in carbohydrate content. Haylage is the only type of winter forage that has sufficient concentrations of exchange energy, protein, carbohydrates and carotene, satisfying needs of highproductive livestock in nutrients. Haylage from Hungarian sainfoin was fed to Holstein BlackandWhite cows in the frame of experiments conducted in 2018. Cows consumed 2.3 3.9 kg more of dry matter (DM) with the haylage, compared to hay (control). Digestibilities of DM and organic matter were 2.55 5.80 and 2.54 4.14 higher than in the control group, respectively. For 120 days the experimental groups produced 3993 27.2 and 4144 31.9 kg of milk versus 3910 45.4 kg of the control one. The former also exceeded the latter in milk fat and protein contents. Fodder costs per 1 kg of milk amounted to 0.74 energy feed units in the control and 0.71 and 0.69 energy feed units in the experimental groups.

История сельского хозяйства включает в себя многолетний опыт применения биологических консервантов для силосования. Однако, учитывая различную эффективность препаратов, предлагаемых на рынке, а также инфляцию научного слова в угоду маркетинговым стратегиям, сложно найти действительно качественный и эффективный консервант. Кормовой потенциал, который заключается в питательности силоса и его гигиеническом статусе во многом определяет эффективность животноводческих хозяйств. Поэтому важно учитывать как можно больше факторов в цепочке производства кормов, влияющих на продуктивность и здоровье животных, особенно тех факторов, которые поддаются корректировке. Различную эффективность микробиологических препаратов можно отнести к подобным детерминантам. В статье дана оценка консервирующим способностям препаратов, которая выражена в степени подкисления и сохранении кормовой ценности. Полученные данные дают возможность установить опосредованную роль биологических консервантов в молочной продуктивности коров. Эксперименты проводили в 2019 году на базе СПК «Кобраловский» Ленинградской области. В траншеи закладывался силос из многолетних трав (смесь злаковых и бобовых культур). Во время закладки провяленная зелёная масса тщательно трамбовалась, после завершения трамбовки закрывалась плёнкой. Препараты вносились, исходя из рекомендаций производителей консервантов, с помощью насосно-дозирующего комплекса уборочного комбайна. Консерванты были представлены в сухой и жидкой форме. Через 30–35 дней, после окончания ферментации силоса, отбирали образцы готового корма для оценки биохимических показателей (питательности, содержания органических кислот). Готовый корм, заготовленный с биоконсервантом «Биотроф 2+», содержал сырого протеина на 24,3% больше, чем корм, заготовленный с английским препаратом, и на 31,6% больше по сравнению с препаратом шведского производства. Наблюдалось увеличение среднесуточного удоя молока 4% жирности у коров, которым скармливали силос, заготовленный с закваской «Биотроф 2+», на 5,1% в сравнении с группой коров, которым скармливали силос, заготовленный с английской закваской, и на 8,4% — с шведским консервантом. Bio-preservatives are widely used in agriculture for silage production. A large variety of preparations makes it difficult to select an effective preservative of high quality. Silage nutritional value and quality directly affect animal farming. Therefore, the more factors of forage production are considered the higher livestock productivity and health level. This article reports on preservative efficacy determined by acid composition and nutritional value. The obtained data demonstrated an indirect impact of bio-preservatives on milk productivity. The investigation took place at the SPK “Kobralovskiy” in the Leningrad region in 2019. Silage was composed of gramineous and legumes. Wilted green mass was thoroughly rammed and covered subsequently. Preparations were applied by a dosing complex of a harvesting machine according to manufacturer instructions. Liquid and dried preparations were used. Silage samples were tested 30–35 days post fermentation. Silage prepared by “Biotrof 2+” exceeded two foreign preservatives by 24.3 and 31.6% in crude protein. Feeding cows with “Biotrof 2+” silage increased the average daily yield of 4% milk by 5.1 and 8.4% compared to the preservatives made in England and Sweden, respectively.

According to the results of the analysis, it was determined that the maize varieties examined showed statistically significant differences in plant properties, dry grass and silage quality. Average plant height, number of leaves, leaf ratio, stem diameter, number of cob, stem ratio, cob ratio and green grass yield were 249.9 cm, 12.97 plant/piece, 19.24%, 22.08 mm, 0.93 plant/unit, 38.40% and 4,251.57 kg/da respectively. According to the analysis, it was observed that the average crude protein content, ADF ratio, NDF ratio, crude ash content, digestible dry matter ratio, crude protein yield, dry matter rate, dry matter yield and hay yield were 8.80%, 34.91%, 59.7%, 7.2%, 61.7%, 993.9 kg/ha, 29.4%, 11,640 kg/ha 12,570 kg/ha in dry grass, respectively. For the silage of varieties, the average crude protein content, ADF ratio, NDF ratio, pH, digestible dry matter rate, dry matter ratio, crude protein yield and Fleig score were 8.22%, 29.27%, 50.48%, 3.57, 66.1%, 28.14%, 926 kg/ha and 118.35, respectively. Burak, Sasa 1 and Ada 334 genotypes performed better in terms of green yield per hectare (53,650, 50,290 and 45,630 kg/ha) and dry matter yield (14,710, 12,810 and 12,410 kg/ha). These varieties can be recommended to producers as silage maize varieties under second crop conditions in Çukurova region of Turkey.

The introduction and use of herbaceous legumes may contribute to agricultural intensification, especially in the context of sustainable crop and livestock production systems. In the context of evaluating different legume species for these systems in moist savanna zone of West Africa, the present study involved the evaluation of 46 accessions of Lablab purpureus (L.) Sweet between 2000 and 2002 at Samaru, Zaria in the northern Guinea savanna of Nigeria to identify accessions with the potential to contribute to grain or forage production and those with the potential for multiple use. Grain yields (0·6–2·4 t/ha) with a mean seed crude protein and phosphorus content of 25·3 and 0·46 g/kg, respectively, were obtained. Dry matter yields (leaf: 0·3–3·1, stem: 0·2–4·6, root: 0·03–0·3 t/ha) were produced between 40 and 140 days after planting. Within this same period up to 1152 kg shoot crude protein/ha, equivalent to 184 kg N/ha, were recorded for accessions. Ten accessions that may contribute to grain production, eight accessions that may contribute to forage production and six accessions with drought tolerance were identified. Some white-seeded accessions (Grif 1246, ILRI 4612 and PI 183451) with good grain and forage yield and high-protein content have the potential to provide more and higher quality food for people and feed for livestock. The observed potential to contribute to grain production for protein-rich food, feed for livestock and green manure for soil N improvement suggests lablab may be an acceptable legume option for use in cereal-legume-livestock systems in the moist savanna zone of West Africa.

Trifolium Repens L

Исследования выполнены в Пензенской области в 2014 2018 годах. Клевер ползучий (Trifolium repens L.) многолетнее травянистое растение, которое можно использовать для коренного улучшения состояния лугов и пастбищ. Цель селекционной работы с клевером ползучим в Пензенском НИИСХ создание сорта с урожайностью зелёной массы 14 16 т/га, устойчивой семенной продуктивностью (150 250 кг/га), выдерживающего трёхчетырёхкратное стравливание или скашивание, переносящего кратковременную засуху, пригодного к механизированной уборке семян. Представлена характеристика нового сорта клевера ползучего Изумруд, переданного в 2018 году на государственное сортоиспытание. Метеорологические условия отличались по годам исследования, что позволило достаточно полно оценить перспективность сортобразца. По результатам трёх циклов конкурсного испытания (2015 2017 годы) урожайность зелёной массы нового сорта Изумруд составила 19,48 т/га, сбор сухого вещества 4,34 т/га, урожайность семян 151 кг/га, что на 13,7, 18,4 и 18,9 выше стандарта ВИК 70 соответственно. Содержание сырого протеина в сухом веществе составило 22,4 26,9, клетчатки не превышало 27 31. Повреждаемость вредителями слабая, поражаемость бурой пятнистостью и мозаикой клевера ползучего слабая, ниже стандартного сорта. Сорт высокоустойчив к корневым гнилям, раку клевера, аскохитозу. Сорт Изумруд пригоден к механизированной уборке семян. Высокая засухоустойчивость (5 баллов) и зимостойкость (96 100) нового сорта позволяет рекомендовать его для сенокосного и пастбищного использования во всех зонах распространения культуры. Экономический эффект при использовании на кормовые цели составляет 11,2 тыс. руб./га, на семена 7,2 тыс. руб./га. The investigation took place in the Penza region in 2014 2018. Breeding of a new white clover variety aimed at the development of a genotype that had green mass productivity of 14 16 t ha1, stable seed yield of 150 250 kg ha1, high resistance to triple or quadruple cutting, shorttime drought and automized harvesting. This paper gives the description of white clover Izumrud that was sent to the State variety trial in 2018. The variety was tested under the different weather conditions. Three years of the competitive variety trial (2015 2017) showed that its green mass productivity amounted to 19.48 t ha1, dry matter (DM) content 4.34 t ha1, seed yield 151 kg ha1, exceeding the standard variety (VIK 70) by 13.7, 18.4 and 18.9, respectively. Crude protein content was 22.4 26.9, fiber up to 27 31. Izumrud also exceeded VIK 70 in tolerance to pests, Pseudopeziza trifolii and mosaic virus. The variety had high resistance to root rot, clover wilt and Ascochyta leaf spot. It tolerated automized harvesting, drought and cold and was recommended for farm cultivation. Its economic efficiency amounted to 11.2 thousand RUB ha1 under forage production and 7.2 thousand RUB ha1 under seed production.
