The performed investigations aimed at assessing the welfare of horses in accordance with the rules and methods of zoohygienic inventory. The investigations were performed and the measurements taken at the Wolica riding complex of Warsaw University of Life Sciences. The basic parameters creating the microclimate were evaluated in the research described in the paper "The welfare of horses assessed by the investigations of chosen parameters of the stable microclimate" published in the present issue of Animal Science. Using the rules and methods of zoohygienic inventory the current paper presents the farm buildings, their equipment, ventilation system and closest surroundings in which the horses are kept. The investigations included the concentration of ammonia in the stables, to demonstrate the effectiveness of drains and ventilation. The obtained results were compared with the binding standards. The obtained results show that the parameters agree with zoohygienic recommendations and exceed the standards only sporadically. The welfare of animals was maintained.

Dobrostan koni oceniony metodą inwentaryzacji zoohigienicznej. Celem przeprowadzonych badań była ocena dobrostanu koni zgodnie z zasadami i metodyką inwentaryzacji zoohigienicznej. Badania i pomiary przeprowadzono na terenie kompleksu hippicznego Wolica SGGW. Podstawowe parametry tworzące mikroklimat oceniono w „Dobrostan koni oceniony z wykorzystaniem badań wybranych parametrów mikroklimatu stajni" opublikowanym w aktualnym numerze Animal Science. W niniejszej pracy, postępując zgodnie z zasadami i metodyką inwentaryzacji zoohigienicznej, opisano budynki inwentarskie, ich wyposażenie, system wentylacji i najbliższe otoczenie, w którym utrzymywane były konie. Zbadano stężenie amoniaku w pomieszczeniach, a otrzymane wyniki zestawiono z obowiązującymi normami. Uzyskane wyniki wskazują, iż badane elementy środowiska koni były zgodne z zaleceniami zoohigieny i tylko sporadycznie przekraczają normy. Dobrostan pod tym względem był zachowany.

The mathematical model to analyze ammonia concentrations inside lifestock facilities has been made. The regression relationship of the intensity of the ammonia evaporation in the pigsty for the farrowing sows and their piglets has been determined. When the surface of the concrete floor of the stall is uneven and there is a manure layer of 0.5-1.0 cm thickness, the ammonia concentration in the pigsties of sows with piglets exceeds the upper permissible limit (20 ppm). When the relative humidity of the air is normal and the ammonia concentration exceeds the permissible limit, it should be reduced by technical and zoohygienic means ( by carefully cleaning the floor surface). This lowers the ammonia concentration from 25 ppm to 10-15 ppm, and its emission.

This paper of the selected groups of nitrogen cycle bacteria in the Biebrza River was analysed. In the water samples the quantity of ammonifying bacteria, nitrifying bacteria, proteolitic bacteria was estimated and also selected water quality indicators were analysed. Large quantities of proteolitic bacteria and ammonifying bacteria were found while the quantity of nitrifying bacteria was very small. Water quality analyses proved high TOC concentrations and low nitrate as well as nitrite concentrations. It was found, that the mineral forms of nitrogen being the intensive product of organic matter degradation is not released (low concentrations of ammonia), but it is accumulated in microorganisms cells. Low concentrations of ammonia are limiting for the number of nitrifying bacteria. The seasonal character of the occurrence of all analysed bacteria groups was as well found. The analytical procedure used was adjusted for bacteriological research on rivers of low anthropopressure.

W niniejszej pracy zbadano występowanie wybranych grup bakterii cyklu azotowego w rzece Biebrzy. W próbach wody oznaczono liczebność bakterii proteolitycznych, amonifikacyjnych i nitryfikacyjnych. Określono poziom wybranych wskaźników jakości chemicznej. Stwierdzono wysoką liczebność bakterii proteolitycznych i amonifikacyjnych oraz bardzo niską bakterii nitryfi kacyjnych. Badania chemiczne potwierdziły wysokie stężenia OWO i niskie stężenia azotynów i azotanów. Stwierdzono, że mineralne formy azotu intensywnie powstające w wyniku degradacji materii organicznej nie są uwalniane do środowiska (niskie stężenia amoniaku), a kumulowane w komórkach mikroorganizmów. Niskie stężenia amoniaku działają hamująco na liczebność bakterii nitryfikacyjnych. Stwierdzono ponadto sezonowość występowania wszystkich badanych grup bakterii. Dostosowano procedurę analityczną do wykorzystania w badaniach bakteriologicznych rzek o niskiej antropopresji.

The present studies were concentration of ammonia, nitrite, nitrate, dissolved oxygen, temperature, salinity and pH. For seven physicochemical parameters were determined in marine water samples along with marine ornamental fish water sources from CAS in marine biology laboratory conditions at Parangipettai. Water sample have been studied at a marine water sources. The study concentrations of parameters like ammonia, nitrite, nitrate, dissolved oxygen, temperature, salinity, and pH. And physicochemical parameters have been calculated. The data showed the difference of the investigated parameters in samples as follows; Concentration of water quality parameters like ammonia was maximum level above 1.158 μmol¯1, nitrite was ranging from 0.811 to 0.922 μmol¯1, nitrate was range maximum level above 4.84 μmol¯1, dissolved oxygen content was maximum level above 2.4 mg¯1, temperature was ranging from 32.3 to 100 °C, salinity values ranging from 0 to 36ppt and pH was ranging from 6.5 to 8.0. During the study period of from July 2013 to June 2014 we investigated concentration of seven physicochemical parameters value Marine water samples with cultured fish species in presence of water from CAS in Marine Biology laboratory Annamalai University at Parangipettai.
