L’insuffisance des ressources fourragères naturelles constitue une contrainte majeure au développement de l’élevage des ruminants dans le Centre et Nord bassin arachidier sénégalais. Pour y faire face, il faut recourir à des techniques telles que la culture fourragère. L’objectif est donc d’étudier la production de fourrage de Mucuna pruriens dans la zone et de déterminer sa valeur nutritive. Du fourrage frais de 79-84 jours et des foins de 60, 75 et 90 jours ont été produits. Les rendements ont été mesurés, les fourrages analysés, les compostions chimiques et les valeurs nutritives déterminées. Les rendements sont globalement faibles, 1,16 à 1,50 t MS/ ha, mais comparables à certains rapportés dans la littérature. Le fourrage frais est plus riche en protéines brutes que les foins, soit 19,56 contre 14,16 à 18,65% de la MS, moins fibreux, soit 27,26 contre 33,82 à 35,27% de la MS et plus nutritif, soit 150,65 contre 96,60 à 141,48 g/ kg MS de protéine brute digestible et 0,70 contre 0,67 à 0,69 UF/ kg MS. Parmi les foins, celui de 75 jours offre un léger avantage. En définitive, cette culture reste possible dans cette zone et peut y être préconisée en vue d’une atténuation du déficit fourrager.

DC. var. utilis (Wall. ex Wight) Baker ex Burck) cv. Ghana cultivated in the Center and North senegalese groundnut basin The insufficiency of natural fodder resources constitutes a major constraint to the development of ruminant farming in the Central and Northern senegalese groundnut basin. To deal with this, techniques such as forage cultivation must be used. The objective is therefore to study the forage production of Mucuna pruriens in the area and determine its nutritional value. Fresh forage of 79-84 days and hay of 60, 75 and 90 days were produced. Yields were measured, forages analyzed, chemical compositions and nutrient values determined. Yields are generally low, 1.16 to 1.50 t DM / ha, but comparable to some reported in the literature. Fresh forage is richer in crude protein than hay, 19.56 against 14.16 to 18.65% DM, less fibrous, 27.26 against 33.82 to35.27% DM and more nutritious, 150.65 against 96.60 to 141.48 g/kg DM of digestible crude protein and 0.70 against 0.67 to 0.69 UF /kg DM. Among the hays, that of 75 days offers a slight advantage. Ultimately, this crop remains possible in this area and can be recommended there with a view to reducing the fodder deficit.Keywords: Yield, chemical composition, fresh fodder, hay, nitrogen value, energy value.

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.

SUMMARYThe nutritional value of dried poultry excreta was investigated by determining the apparent digestibility of dry matter, organic matter, nitrogen, energy and copper in five diets containing 0 to 100% of this feed. Dried poultry excreta supplied 20·21% apparently digestible crude protein and approximately 1·57 or 1·74 Mcal of metabolizable energy per kg dry matter.The copper in dried poultry excreta was found to be less digestible than the copper in barley. It is concluded that, as far as copper levels are concerned, dried poultry excreta are safe for ruminants, and are a source ofcheap protein. More detailed work is needed to determine the metabolizable energy of the material accurately.

This study aimed to assess productivity and nutritional value of the tropical grasses Brachiaria brizantha cv. Piatã, Xaraés, and Marandu, Panicum maximum cv. Mombaça, and B. ruziziensis cv. Kennedy in the interseason of an integrated crop-livestock (ICL) system since alternatives are needed for forage production for animal grazing in Autumn and Winter. The experimental design was a randomized block design in a split-split plot scheme with four replications. The treatments of plots consisted of five grasses, subplots consisted of three cropping systems (monoculture, intercropping with corn and unsuppressed grass, and intercropped with corn and suppressed grass), and sub-subplots consisted of four cutting intervals of grasses (50, 90, 125, and 195 days after emergence - DAE). The experiment was carried out from February to September 2014. Dry matter (DM) productivity, obtained at 195 DAE for the three cropping systems (monoculture grass, unsuppressed and suppressed grass in intercropping), were 18.45, 7.15, and 3.05 t ha?1, respectively, and average crude protein contents of leaf blades of grasses decreased linearly between the cutting intervals of 50 to 195 DAE from 19.95 to 9.70%, respectively. Under integrated systems, the studied grasses showed better yields and nutritional quality when compared to traditional grazing systems. Panicum maximum cv. Mombaça and Brachiaria brizantha cv. Xaraés and Piatã had the highest leaf and crude protein yields when compared to Brachiaria ruziziensis cv. Kennedy and Brachiaria brizantha cv. Marandu. In terms of nutritional value, Brachiaria ruziziensis cv. Kennedy was superior to Mombaça and Xaraés grasses but had lower total dry matter yield. Finally, Xaraés, Piatã and Mombaça grasses are recommended choices ICL systems when fodder grass production is the goal.

The consumption of edamame [Glycine max (L.) Merr.] in the US has rapidly increased due to its nutritional value and potential health benefits. In this study, 10 edamame genotypes were planted in duplicates in three different locations in the US—Whitethorne, Virginia (VA), Little Rock, Arkansas (AR), and Painter, VA. Edamame samples were harvested at the R6 stage of the bean development when beans filled 80–90% of the pod cavity. Afterward, comprehensive chemical composition analysis, including sugars, alanine, protein, oil, neutral detergent fiber (NDF), starch, ash, and moisture contents, were conducted on powdered samples using standard methods and the total sweetness was calculated based on the measured sugars and alanine contents. Significant effects of the location were observed on all chemical constituents of edamame (p < 0.05). The average performance of the genotypes was higher in Whitethorne for the contents of free sucrose (59.29 mg/g), fructose (11.42 mg/g), glucose (5.38 mg/g), raffinose (5.32 mg/g), stachyose (2.34 mg/g), total sweetness (78.63 mg/g), and starch (15.14%) when compared to Little Rock and Painter. The highest soluble alanine (2.67 mg/g), NDF (9.00%), ash (5.60%), and moisture (70.36%) contents were found on edamame planted in Little Rock while edamame planted in Painter had the highest crude protein (43.11%) and oil (20.33%) contents. Significant effects of genotype were observed on most of the chemical constituents (p < 0.05) except NDF and raffinose. Among the 10 genotypes, R13-5029 consistently had high sucrose content and total sweetness across the three locations, meanwhile it had relatively high protein and fiber contents. Overall, the results indicate that to breed better edamame genotypes in the US, both genotype and planting location should be taken into considerations.

A cutting experiment was conducted to test the changes in botanical composition, yield and nutritional value of forage, obtained in conditions of simulated rotational spring grazing on permanent grassland. The experiment was carried out on permanent pasture in vicinity of Sabac, Serbia in 2015 included three cuttings as a simulated rotational spring grazing. The highest share of grasses was noted in the first cut and decreased in the second and third cut, with increased forbs participation, and relatively constant percentage of legumes. The highest dry matter (DM) yield was obtained for the first harvest, followed by the second cut, and the lowest forage production was determined for the third harvest, with only 11.04 and 17.42% of the first and second cut yield. There were not found the significant differences between cuts for herbage DM and crude protein content. Markedly lower value for non-protein N concentration (p<0.05) was determined in the third cut. The fiber content increased during the grazing season (p<0.05), with the highest value determined in the herbage obtained in the second cut. The highest energy values (p<0.05) had the herbage produced in the first cut (DM basis), wherein the lowest values were found in the forage from the second harvest. These results indicate that especially herbage yield of analyzed grassland as chemical composition and nutrition value are highly variable during the growing season. The accurately defined optimal period for using is necessary to provide the high-quality forage for grazing animals.

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.
