Approximately 40% of the airborne pollution of N is in NH₃ form. Approximately 90% of the NH₃ comes from agriculture, and losses from ventilated animal houses make up 18-37%. NH₃ evaporating from animal houses is harmful for the animals, people and the environment. Thus, not only the greatest...

A study on the effect of the development of animal housing technologies in EU and some basic information on the technological data on cattle and pig housing technology introduced in Lithuania in recent years was conducted. Under production conditions, ammonia emission was studied in three types of...

36 litters of sucking pigs were used in the trial from birth till 55 days of age. The lying areas for the experimental pigs were fitted with 0.9 m² area creep boxes having 0.34 m² holes and made from wood fibre slabs. Four groups of sucking pigs were used in this trial. Group 1 had access to the...

Under production conditions ammonia emission was studied in three types of cowshed (in an insulated cowshed of tied cows; in an uninsulated cowshed with laying boxes and open manure tracks; and in a cowshed with the insulated roof, boxes and partly slatted floor). During the housing period the NH₃...

The health and high productivity of dairy cows need to be ensured in order to create sustainable dairy production. Therefore, it is very important to create a good microclimate in the barns. Most of the microclimate problems are in cowsheds, where it is difficult to ensure that the air is warm and...

The av. daily gains of growing pigs on deep litter and in "double stalls" with litter were 58-108 and 55-70 g higher resp. than those of pigs on a concrete floor without litter. The amount of straw required was 10 times less for double stalls than for deep liter.

The study was conducted to determine the effect of growth environment of 2-month-old sucking piglets on their weight gains at the pig farm in Skėmiai between 2006 and 2007. The piglets born indoor and outdoor were weaned at 2 months old, and were raised indoor until the end of the finishing period. ...

The present study was designed to analyse and evaluate stockbreeding development according to requirements of environment in different regions of Lithuania. Stockbreeding development was analysed on the background of data of crop declaration, animal registration, biogenic pollution of rivers and...

The microclimatic conditions, microbiological environment, welfare and health of animals in an uninsulated cow shed were studied. According to heat and moisture balance equations and the conditions preventing water vapour condensation on the internal surface of the external barriers, a mathematical ...

The study was aimed at developing methodical guidelines for equine behavioural studies for horse breeders and specialists. The prepared methods were tested in three horse breeding centres of northern Lithuania with the horses of the Žemaitukai and saddle breeds (Lithuanian saddle, Baltic...
