Darbo tikslas – įvertinti inokuliantų panaudojimo efektyvumą siloso gamyboje. Tyrimo metu nustatyta inokulianto nauda daugiamečių žolių ir kukurūzo silosuojamai masei skirtingais laikotarpiais 30–60–90 dienų, mokslininkai taip pat teigia apie inokulianto teigiamą poveikį silosui. Inokuliantas sausąsias medžiagas daugiamečių žolių ir kukurūzų silose paveikė skirtingais laikotarpiais, daugiamečių žolių silose inokuliantas sausąsias medžiagas pakėlė iki 372±37–401±37 g/kg (norma 300–500 g/kg), o kukurūzo silose rezultatus pamažino iki siektinos normos 320–360 g/kg, kai gauti rezultatai buvo 325±11,7–333±11,7 g/kg su inokuliantu. Tiriant rūgštingumą daugiamečių žolių silose inokuliantas pakėlė reikšmes 4,3±0,2–4,5±0,2 ir išlaikė vienodą kokybę skirtingais laikotarpiais. Didesnį pokytį inokuliantas turėjo kukurūzų siloso pH, nuo labai rūgštaus 3,5±0,3 rodiklio pakilo iki 3,9±0,1 su inokulianto įtaka. Žolės silosas be inokulianto nepasiekė siektinos vertės 160–190 g/kg, o su inokuliantu žalių baltymų kiekis silose buvo 177±3,1–179±3,1 g/kg. Kukurūzų silose esantiems žaliems baltymams inokuliantas turėjo teigiamą poveikį, skirtingais laikotarpiais žymaus pokyčio nepastebėta, bet gautas rezultatas 67±9,5–75± 9,5 g/kg patenka į siektiną vertę 75–85 g/kg.

The goal of the research is to determine the energy consumption of technological equipment for technological processes performed by fully robotic dairy farm. During the research it was established that 4.46 Wh (0.006 Eur) is used to obtain 1 Liter of milk. Which makes up 1.83% of the wholesale price. During the study period which took place in fully robotic dairy farm with most advanced technologies such as: feeding, milking, manure removal robots, etc., the total electricity consumption of all technological was determined – 351.4 kWh per day. Due to the selected study period and the low air temperature, the 10 fans in the cowshed with a total power of 7.5 kW were not measured. Measured electricity consumption reveals the importance of innovative farm technologies. While maintaining the high sustainability of technology, we can single out the feeding robot, which consumes 24.1 kWh per day and completely replaces the use of diesel. Robot distributes feed, supplies fresh feed and increases the activity of cows in the automated milking system.

Integrated pollution prevention and control systems are necessary to reduce the environmental impact of pollution from livestock farms and to prevent the transfer of pollutants from one envi-ronment to another. In intensive livestock farms, various technological and administrative measures should be taken to reduce environmental pollution, as the compatibility of these measures avoids the risk of contamination of the environment. The work was performed in VMU Laboratory of Thermal Energy Processes and Emissions in 2018. The paper analyzes the physical properties of wheat and rapeseed straw pellets and their ap-plication possibilities for liquid manure reservoir covering and the impact of straw granules on ammonia emission reduction. It has been found that ammonia emissions from liquid manure are reduced by 72–78% using rapeseed pellets.

One of the main tasks of agriculture is to increase the yield of agricultural crops. There is an obstacle to increasing yields, which is the weediness of the fields. The most favorable factor in increasing soil fertility is mulching. The aim of this work was to analyse the physical properties of organic granular mulch and to evaluate their residual influence on the physical-mechanical properties of the soil. Experimental researchers found when sunflower husk pellets had the highest compressive strength, as well as particularly relevant transport pellets. The residual effect of organic mulch layer thickness on soil hardness, with the lowest hardness in smaller soil layers (0– 5 cm), was in use of wheat straw pellet mulch.

The microclimate of the cowshed affects 20–30% of livestock productivity. The microclimate in the cowshed consists of air temperature, relative humidity, air velocity, lighting, harmful gas concentration. Animal productivity and animal health depend on the microclimate of the cowshed. Ensuring a proper cowhide microclimate keeps cows productive and healthier, which results in lower investment in cow treatment and steady productivity growth. The aim of the study was to evaluate the influence of the microclimate of the studied cowshed on milk yield. Studies have shown that the cowshed meets the optimal microclimate requirements, but a drop in milk yield was observed. During the study period, the average air temperature in the bed was found to range from 2.52°C to 27.79°C, with a relative humidity of 43.27% to 89.25%. When the decrease in milk yield was observed, theoretical calculations were performed, according to which 54 kg of raw milk was lost per day due to the relative air pressure, which was > 72%.
