The development of animal husbandry requires the annual production of a sufficient amount of high-quality feed, their nutritional balance, which cannot be achieved without perennial legumes and legume-cereal mixtures. The content of nutrients in the dry matter of forage depends on both the composition of the grass mixture and the mode of use of the grass stand. Therefore, the main reference point for modern feed production should be an innovative development model that will ensure the production of feed with specified quality parameters. Goal and tasks. Determine the effect of the composition of grass mixtures and the mode of use on the fodder value of the grass stand, in particular, the content in dry matter of fodder units, crude protein, gross and metabolic energy. Research methods. System analysis, field, laboratory, comparative calculation. Results. Perennial legumes and legume-grass mixtures are the main source of protein for livestock. According to the results of three-year studies, it was found that regardless of the composition of grass mixtures in the tri-grass regime of grass use, the content of crude protein in the dry weight of feed was much higher compared to the two-grass regime of grass use. And a high content of crude protein was in the dry mass of the forage from the grass mixture of birdsfoot trefoil with tail grass. So, with a three-time alienation of the yield of the leafy mass of the grass mixture, the birdsfoot trefoil with tail grass, had a high content of crude protein: 13.93 – in the first, 15.83 – in the second and 15.09% – in the third slopes. Replacement of the two-oxide mode of use with trioxide increased the content of exchange energy from the first cut of the grass mixture with birdsfoot trefoil with tail grass by 0.19 MJ/kg of dry matter, and of the grass mixture of birdsfoot trefoil with bromus inermis – by 0.18 MJ/kg of dry matter. Conclusions. Thus, in the triangular mode of use of larch-grass stands, the nutritional value of the feed was higher compared to the two mowings. Thus, with three-time alienation of the crop of leaf mass, the content of feed units was 0.76-0.82, metabolic energy – 8.77-9.15 MJ/kg, while with double mowing – respectively 0.75-0.80 and 8,75-9.03 MJ/kg of dry matter

Sunn Hemp

Maize is an ideal forage crop for ensilage because of its high levels of fermentable carbohydrates, although it is low in protein. Sunn hemp is a legume with a high crude protein content with potential to be used in combination with maize to provide a silage with a higher protein content. Different percentages of sunn hemp-maize mixtures of 80-20, 60-40, 40-60 and 20-80 respectively were compared to silages of sole maize and sunn hemp. In the laboratory study, DLG classifications (color, smell, structure, total score and quality class), silage loss (%), silage pH, dry matter content, flieg score, crude protein content, crude ash content, NDF, ADF, metabolic energy (MJ kg-1 DM), dry matter intake, percent digestible dry matter and relative feed value were determined at the end of 60 days ensilage. The crude protein contents of silages increased as the sunn hemp ratio in the mixtures increased. In addition, pure sunn hemp silage and mixtures, especially 80% sunn hemp mixed with 20% maize, were found suitable for silage and it was concluded that sunn hemp and sunn hemp-maize silage mixtures could be used in animal husbandry.

Purpose. To evaluate a promising selection sample of the Psathyrostachys juncea (Fisch.) Nevski for its adaptability to the agro-climatic conditions of the Right-Bank Forest-Steppe and on its basis to create a highly productive multipurpose variety. Methods. System analysis, field, laboratory, comparative calculation. Results. It has been established that Psathyrostachys juncea acquires optimal hay ripeness in the end of the first–at the beginning of the second decade of May, which is 12-13 days earlier in comparison with awnless bromegrass and crested wheat grass. The forage productivity of the green mass of the Psathyrostachys juncea for two mowings ranged from 3.31 kg/m2 in 2018 to 4.90 kg/m2 in 2017 and on average over the years of research was at the level of 4.15 kg/m2, or 41.5 tons/ha, while the yield of dry matter averaged 1.40 kg/m2. It is proved that the forage productivity of the Psathyrostachys juncea for the three years of use primarily depended on meteorological conditions during crop formation. The content of nutrients during the years of research was: crude protein – 14.84, fat – 2.36, fiber – 21.89 and ash – 7.46%, which meets the requirements of highly nutritious feed, especially for beef cattle farming. Conclusions. Psathyrostachys juncea (Fisch.) Nevski enters into the phase of mowing ripeness in conditions of the Right-Bank Forest-Steppe 12-13 days earlier in comparison with other studied perennial grasses. The dry matter yield averages 1.40 kg/m2 with a deviation over the years from 1.20 to 1.65 kg/m2. The value of forage productivity of this species is strongly influenced by meteorological conditions during crop formation. The content of nutrients over the years of the research was: crude protein –14.84, fat – 2.36, fiber – 21.89 and ash – 7.46%. According to the results of the research, the Askanijskyi cultivar of the Psathyrostachys juncea (Fisch.) Nevski variety was submitted for the qualification examination in the system of the state variety testing (application №19658001 dated 21.10.2019).

Abstract. The purpose of the research is to study is to establish the effectiveness of different methods of grassing old-aged degraded haylands with the participation of species of cereals and legumes recommended for agrophytocenoses of the zone of unstable moisture. The methodological basis of the approach to restoring the productivity of degraded haylands on saline leached chernozems was the improvement of their phytocenotic structure, based on the coenotic usefulness of the dominant species of legumes and grasses. Results. Highly plastic species of legumes and grasses have been identified, which allow forming productive haymaking on the site of degraded old-growth grass stand for 10 years of its use. The legume-cereal agrophytocenosis formed on the cenotic basis contributed to the production of energy-saturated feed (0.74–0.76 feed units per 1 kg of dry matter with a content of 14.6–15.8 % crude protein). The conducted studies of methods for improving the grass stand did not reveal a significant advantage of the amelioration over the simplificated improvement (accelerated grassing). With accelerated grassing with the use of disking with sowing of perennial grasses in the treated turf, the productivity of the grass stand was slightly lower compared to the amelioration, but due to the reduction of technological costs, this method is more economically justified compared to the traditional method of tillage. Scientific novelty. For the first time in the conditions of the zone of unstable humidification of the Central Ciscaucasia in a comparative aspect, two methods of improving degenerated low – productive the grass amelioration and simplificated improvement (accelerated grassing) against the background of the use of nitrogen-phosphorus fertilizers with the participation of dominant species of cereals and legumes of perennial grasses recommended for their introduction into the plant communities of this zone were studied.

In the course of the experiment, the effect of increasing doses of nitrogen fertilizers on the yield of clover of the meadow variety Nadezhny, entered in the State Register of Breeding Achievements in 2012, was analyzed. A comparison is also made of this influence with the timothy of the meadow variety Leningradskaya 204. It was established that the pre-sowing introduction of mineral nitrogen for clover and timothy has influenced the productivity of these crops, but the nature of this effect varies depending on the type of grass. The introduction of N20 against the background of P30K90, which provided an increase in control of 51.2% for green mass and 33.6% for air-dry matter, was optimal for meadow clover of the first year of life. For grassland clover second year of life, the best option was N0P30K90, which gave an increase of 56.6% to the control on green mass and 50.6% on air-dry matter. A further increase in the dose of nitrogen on the options caused a decrease in yield increase. Timothy meadow for two years of life was traced responsiveness to the provision of nitrogen. The most productive in all respects was the option N120P30K90.

The purpose is to determine the productivity of perennial legume and cereal grasses under conditions of natural moisture supply in South Steppe of Ukraine. Method. The studies were conducted during 2016—2018 using conventional methods, and the output of feed units, digestible protein per unit of area was determined by reference books. Results. On average over three years of research, the highest yield of leaf-stem mass of cereals was formed by Bromus inermis and Elytrigia medium tender – 11.6 and 11.2 t/ha, respectively. The lowest yield was formed by Agropyrum pectiniforme – 7.6 t/ha. Among the all legume grasses, Melilotus albus prevailed (14.8 t/ha). Medicago sativa and Onobrychis arenaria were able to form a similar yield (14.5 and 13.5 t/ha, respectively) under the arid conditions of South Steppe of Ukraine. Insufficient rainfall in 2017 caused a decrease in the productivity of the studied crops. Thus, in 2017 the average yield of green mass in the experiment was 10.3 t/ha, while in 2016 under more favorable weather conditions this figure was 13.2 t/ha or 28.2 % more. The highest output of feed and protein units (FPU) per unit of area under cereal grasses was provided by Bromus inermis (2.35 t/ha). The lowest one was recorded in Agropyrum pectiniforme (1.60 t/ha). FPU output per unit of area under legume grasses increased respectively. Lotus corniculatus provides less green mass and therefore dry matter and forage and protein units. Perennial cereals grasses do not prevail over legume grasses, so they do not spread in South Ukraine. Conclusions. The productivity of perennial grasses in the south of Ukraine significantly depends on the type of plants, weather (hydrothermal) conditions of the year. The most effective is the cultivation of perennial legumes, namely Melilotus albus, alfalfa, Onobrychis arenaria. Bromus inermis and Elytrigia medium prevail among cereal grasses.

The average data for 2018–2019 are presented for yield, dry matter content in grain-haylage mass, nutritional value of test grain-haylage samples produced from plant mass of white lupin, oat and Sudan grass from single and mixed cenosis of different sowing times. The grain-haylage mass was harvested in the phase of brilliantly ripening lupin bean, milky-waxy ripeness of oats and the end of flowering of the Sudan grass. It’s revealed that variants of the second sowing date — 2 decade of May — have the best yield of grain-haylage mass and its dry matter content. The yield of grain-haylage mass in the best variants of the second sowing period exceeded by 7–8 t/ha. According to the nutritional value of grain silage samples (the content of metabolic energy, crude protein, crude ash and carotene), the best results were obtained in most variants of the first sowing period. In content of the metabolic energy and crude protein of 1 kg of dry matter of grain-haylage, the best were variants of the single-species cenosis of lupine and its mixture with oats of the first sowing period. Variants of single-species sowing of lupine and Sudan grass were distinguished by the content of carotene.

Testing of new cultivars of perennial grasses cocksfoot (Dactylis glomerata L.), meadow fescue (Festuca pratensis L.) and tall fescue (Festuca arundinacea Huds.) was carried out on experimental field of the Institute for Animal Husbandry in year 2005. Trial was set according to random block system, on 10m2, soil type carbonate chernozem. Climatic conditions in year of sowing were at the level of average values for several years for daily temperature, 12,40C compared to 12,10C, and for precipitation difference was even greater 831,6mm compared to average calculated for several years of 645,2mm. Main morphological and phenological traits of plants were investigated, plant growth, height at 1st cut, plant regeneration after 10 days, as well as production of green mass and dry matter. All five cocksfoot cultivars had considerably higher yields per cuts, total (2,12-2,69 t ha-1). Two cultivars of meadow fescue showed no significant difference in yield of dry matter (1,84-2,03 t ha-1), whereas cultivars of tall fescue differed highly significantly in this regard (1,84-1,62 t ha-1). Also, main parameters of plant quality, organic matter, content of crude protein, crude fibre and crude fat in the 2nd cut were determined. Investigated cultivars of cocksfoot and tall fescue differed significantly, whereas cultivars of meadow fescue were very similar. Obtained results were processed using variation statistical methods and mean values were tested using LSD test.

The research explores the relation between productivity of binary grass mixture and mineral nutrition. The hypothesis assumes that nutrient value of the same forage depends on mineral nutrition of forage grasses. According to purpose of research, the authors specified the task which is seen to analyze the impact of mineral fertilizers on productivity and nutrition of forage mass of binary grass mixture sown under the cover. The object of the research is a binary grass mixture based on alfalfa (Medicago + sainfoin). Sowing was carried out under the barley and Sinapis cover on two mineral backgrounds: control (without fertilizers) and fertilized. Fertilizers were applied the day before sowing. Crop yield and the quality of harvested mass were assessed in the appropriate period which was the stage of Medicago budding. Two-year industrial and economic experiment highlighted necessity and efficiency of sowing Medicago binar grass mixtures under Sinapis cover with 25% lower sowing rate and apply mineral fertilizers dosed as N23P60K60 in the forest-steppe of Novosibirsk region. This application contributed to the highest output of metabolic energy in dry matter (37 GJ/ha). The authors observed a positive tendency on harvesting from 1 ha of fodder units (2.14 tons), digestible protein (0.35 tons), as well as the yield of dry (3.58 tons) and green mass (13.7 tons). In this variant the authors observed the highest output of metabolic energy in dry matter (37 GJ/ha). There was a positive tendency to harvest fodder units (2.14 tons), digestible protein (0.35 tons) pro 1 ha and get dry (3.58 tons) and green mass (13.7 tons).

The results of research into the creation of a new cultivar of spring common vetch Obskaya 16 are presented. The work was carried out in the period 2014-2017. The goal was set to create a new earlyripening variety with а high fodder and seed productivity, high protein content, and an even ripening of seeds. The vetch cultivar Obskaya 16 was created by the method of hybridization on the basis of genetically different and ecologically-distant genotypes with subsequent multiple selection according to the specified parameters from the Kamalinskaya 611 × Novosibirskskaya hybrid populations. The vetch cultivar Obskaya 16 combines early ripeness with high fodder and seed productivity. The length of the growing season of the new cultivar is, on average, 81 days, which allows for the production of certified seeds annually. During all the years of testing in breeding nurseries, the new cultivar surpassed the standard Kamalinskaya 611 in green mass by 41%, in dry matter by 40%, and in grain by 27%. This cultivar is of mowing type, its average seed yield is 2.43 t/ha, green mass 28 t/ha, dry matter – 5.82 t/ha. The main economic and valuable characteristics of the Obskaya 16 cultivar are as follows: the height of the stem is 85-120 cm, the number of internodes is 19-25, the height of attachment of the lower seed pods is 78 cm. The average number of seed pods per plant is 24, the maximum is 46, the average number of seeds per a seed pod is 7-8. The mass of 1000 seeds is 72.6 g. The colour of the seed coat is mainly black velvet (92%) and brown (8%). Crude protein content is 25.3–30.5%. In 2016 the cultivar of spring common vetch was passed to the state variety testing under the name Obskaya 16. The newly created cultivar surpasses the previously recognized varieties in the region by early ripeness, fodder and seed productivity, as well as high fodder quality.

(Improvement of fermented bagasse quality as animal feed by fermentation through administration of sago flour at different levels)ABSTRACT. Feed plays an important role in livestock production system. Due to limitation of pasture and forege areas, it needs to find new feed alternative as replacement of forage as animal feed. One of feed alternatives as replacement of forage is bagasse. Bagasse has low nutritive content and digestibility. One of the efforts to improve bagasse quality is by fermentation. The purpose of this experiment was to improve nutritive values of bagasse by fermentation method by using Trichoderma harzianum as inoculum. This research was conducted at Animal Nutrition Laboratory, Animal Husbandry Department, Agricultural Faculty, Syiah Kuala University, Banda Aceh from January to April 2015. The experiment was designed by completely randomized design (CRD) with 4 treatments (addition of sago flour at defferent levels); R1 control (0% sago flour), R2 (5% sago flour), R3 (10% sago flour), R4 (15% sago flour) of fermented material. Each treatment has 4 replications, therefore there were 16 units of treatment. Parameters observed in this experiment were nutritive values of fermented bagasse including the contents of dry matter, crude protein, crude fiber and ash. The results of the experiments indicated that fermented bagasse with Trichoderma harzianum by addition of various levels of sago flour had significantly effect (P0, 05) on crude fiber and ash contents. However, there were not significantly difference (P0, 05) on dry matter and crude protein contents. In conclusion, addition of various levels of sago flour by using Trichoderma harzianum at fermented bagasse was able to improve nutritive values of fermented bagasse.
