“…Researchers such as Haartsen (1981), Charles (1981), Konca (2001), Bolla (2005) and Turkoglu et al (2005) reported that a starting temperature for turkey brooding should be between 33 and 36 °C in brooder rings below radiant brooders, and that temperatures near the floor of the room outside the brooding area should be between 29 and 32 °C. This temperature should be reduced 2 -3 °C every week until a temperature of 17 -21 °C is reached.…”

“…The lower critical temperatures for day old and mature pigs and chickens are shown in Table 1 (Clark & McArthur 1994). Charles (1981) recommends housing pigs at 3K above their lower critical temperature. The recommended temperature for broilers over 3 weeks is 21°C.…”

“…The maximum ventilation requirement is the amount of air necessary to prevent the building overheating and the minimum ventilation requirement is the amount of air needed to maintain healthy amounts of oxygen, carbon dioxide and ammonia and sufficiently reduce the humidity in the building. The maximum pig ventilation rate is based on a finishing weight of 100 kg (Randall 1977) whilst that for broilers is based on the weight of a fully grown bird (Charles 1981).…”

The potential impact of climate change by the year 2050 on intensive livestock systems in Britain is assessed through the use of simulation models of farming systems. The submodels comprise livestock feeding, livestock thermal balance and the thermal balance of controlled environment buildings and a stochastic weather generator. These are integrated to form system models for growing pigs and broiler chickens. They are applied to scenarios typical of SE England, which is the warmest region of the country and represents the worst case. For both species the frequency of severe heat stress is substantially increased, with a consequent risk of mortality. To offset this, it would be necessary to reduce stocking densities considerably, or to invest in improved ventilation or cooling equipment. Other effects on production are likely to be small

“…In many of the old tie-stall barns, mangers are directed to the walls and openings in the ceiling to the hay storage above the animal room which may contribute to air exchange. Poor building design and unsuitable microclimate may result in decreased productivity, diseases and risks to animal welfare (Cena and Clark, 1981;Charles, 1981).…”

Indoor climatic status during winter conditions in dairy herds in Bosnia and HerzegovinaThe aim of this cross-sectional field study was to describe climatic status in dairy barns during winter conditions both in lowland and in mountainous regions of Bosnia and Herzegovina. While all the mountain herds had tie-stall systems (MT), eight of the lowland herds had group housing systems (LG) and the remaining 30 herds had tie-stall systems (LT). The mean indoor air temperature (T i ) was around 10 °C across types of barns and in all herds T i was above 0 °C. The mean relative air humidity (RH) was actually highest in the LT-group, but within the recommended level for both LG, LT and MT barns. At the 15 % of the MT barns, 17 % of the LT barns and 38 % of the LG barns the air velocity was > 0.2 m/s. The level of NH 3 was quite low in all groups of barns, although somewhat higher in LT-barns. In none of the barns the level of NH 3 exceeded 3 ppm. Only in one barn (a MT-barn) the level of CO 2 exceeded 3000 ppm. We conclude that the climatic status in most dairy barns in Bosnia and Herzegovina during winter seem to be acceptable.Key words: cattle; dairy cows; housing; climatic status; air velocity; carbon dioxide; ammonia; winter; Bosnia and Herzegovina Zimske klimatske razmere v objektih za krave molznice v Bosni in HercegoviniNamen te presečne študije je bil opisati klimatske razmere v objektih za krave molznice v zimskem času v nižinskih in hribovskih območjih Bosne in Hercegovine. V vseh čredah v hribovskih območjih smo našli vezano rejo (MT), medtem ko so imeli v osmih čredah v nižinskem predelu skupinsko uhlevitev (LG), v preostalih 30 čredah pa vezano rejo (LT). Povprečna temperature zraka v objektih (T i ) je bila okrog 10 °C in v vseh čredah so bile temperature T i nad 0 °C. Povprečna relativna vlaga (RH) je bila najvišja v skupini LT, vendar še znotraj priporočenih vrednosti, tako v LG in LT, kot tudi v MT hlevih. V 15 % MT hlevov, 17 % LT hlevov in 38 % LG hlevov je hitrost zraka presegala 0,2 m/s. Koncentracija NH 3 je bila v vseh hlevih relativno nizka, le v LT hlevih je bila nekoliko višja. V nobenem od hlevov koncentracija NH 3 ni presegla 3 ppm. Samo v enem MT hlevu je koncentracija CO 2 presegla 3000 ppm. Na osnovi teh podatkov sklepamo, da so klimatske razmere v večini hlevov za molzne krave v Bosni in Hercegovini v zimskem času ustrezne.
