“…Ammonia is mainly emitted from manure management (80%), and the remaining 20% is due to the use of mineral nitrogen fertilizers (Bebkiewicz et al 2021). Almost one third of this gas emission (30%) comes from pig production (Mielcarek--Bocheńska and Rzeźnik 2019).…”

Livestock production is the basis of global food production and it is a serious threat to the environment. Significant environmental pollutants are odors and ammonia (NH 3 ) emitted from livestock buildings. The aim of the study was to determine the concentration and emission factors of ammonia and odors, in the summer season, from a deep-litter fattening house. The research was carried out during summer in a mechanically ventilated fattening piggery located in the Greater Poland Voivodeship. Ammonia concentrations were measured using photoacoustic spectrometer Multi Gas Monitor Innova 1312, and odor concentrations were determined by dynamic olfactometry according to EN 13725:2003 using a TO 8 olfactometer. The NH 3 emission factors from the studied piggery, in summer, ranged from 8.53 to 21.71 g•day -1 •pig -1 , (mean value 12.54±4.89 g•day -1 •pig -1 ). Factors related to kg of body mass were from 0.11 to 0.23 g•day -1 •kg b.m. -1 (mean value 0.17±0.06 g•day -1 •kg b.m. -1 ). Odor concentrations in the studied piggery were from 755 to 11775 ouE•m -3 and they were diversified (coefficient of variation 43.8%). The mean value of the momentary odor emission factors was 179.5±78.7 ouE•s -1 •pig -1 . Factor related to kg of body mass was 2.27±1.71 ou E •s -1 •kg b.m. -1 . In Poland and many other countries, the litter systems of pigs housing are still very popular. Therefore, there is a need to monitor the pollutant emissions from such buildings to identify the factors influencing the amount of this emission. Another important issue is to verify whether the reduction techniques, giving a measurable effect in laboratory research, bring the same reduction effect in production buildings.

“…The storage and distribution of livestock manure in farmland can pollute the soil and groundwater [6]. The unreasonable use of livestock manure not only causes environmental pollution, and the generated odour will affect people's mood and behaviour, but also hinder the appreciation of livestock manure [7].…”

For aerobic static composting, fresh cow, pig, and chicken manures were used as feedstock and mixed with 10 % corn straws, which was considered as the bulking agent. In the composting process of different livestock and poultry manures, the changing trends of temperature, pH, conductivity, density, and other parameters were intensively studied. The results were as follows: (1) after the tail biogases of composting systems - using cattle manure, pig manure, and chicken manure - were introduced into the biofilter, the concentration of O2 decreased slightly, but the concentration of CO2 increased. The odour in these tail biogases declined significantly, and thus the biodegradation of tail biogas was obvious. (2) The oxygen consumption in the different periods of the composting process of these three manures was almost the same, and the average oxygen consumption for the three manures was 0.928, 0.937, and 0.945 m3/kg, respectively. Under standard conditions, the density of oxygen is 1.429 g/L, and the average oxygen consumption in the composting processes of these three manures was 1.326, 1.338, and 1.350 kg/kg, respectively.

The aim of the article was to study the dependence of reproductive qualities of sows of Irish origin and growth intensity of their piglets on the influence of technological and design parameters of the microclimate system in the farrowing room. The material of the study was the F 1 sows of the Hermitage Genetics maternal line, which were reared in two sections for farrowing of identical planning, identical construction execution and engineering and technical support, except for the microclimate creation and maintenance systems installed in them. The sows of the control group were kept under the classical valve-type ventilation system, and the sows of the experimental group were kept under the geothermal ventilation system. The analysis of reproductive indicators of the experimental population was carried out using generally accepted statistical methods, one way analysis of variance, evaluation index for a limited number of traits, selection index of reproductive qualities of sows. At the end of the experiment and based on the evaluation of data, it was found that the productivity of sows whose farrowing took place in rooms with geothermal microclimate system, were significantly higher during the study period in the number of piglets at weaning – by 0.70 heads or 5.58% (p ≤ 0.001), their safety – by 4.49% (p ≤ 0.05) and the weight of the nest at weaning – by 2.91 kg or 4.23% (p ≤ 0.05) relative to peers kept in sections for farrowing with the classic valve type of microclimate system. The method of factor analysis of variance allowed to identify a statistically significant effect of the type of microclimate system on these indicators, namely: the number of piglets at weaning with an impact force of 2.01%, the safety of piglets – with an impact force of 2.03% and on the weight of the nest of piglets at weaning – with a force of influence within 2.01%. The results of the evaluation of the reproductive qualities of pigs showed the predominance of livestock kept under geothermal ventilation, both for the use of the evaluation index – by 1.31 points, and for the use of the selection index of reproductive qualities – by 1.33 points. No statistically significant difference between sows and piglets kept under different microclimate systems on indicators such as total number of piglets at birth, number of stillborn piglets, proportion of stillborn piglets, fertility, high fertility, weight of one head at weaning, absolute gain, average daily yield has not been established. Key words: sow, piglets, microclimate system, farrowing, piglet nest weight, safety.
