The rapidly increasing size of livestock production facilities in combination with the ever growing use of chemical fertilizers increases the anthropogenic Green House Gases (GHG) emissions from agriculture. Today agriculture alone is taking a significant part of about 20% of the total anthropogenic GHGs emissions, of which the global bovine dairy sector contributes 4% of the total anthropogenic GHGs emissions. Being responsible for such a significant part of GHG emissions cattle growing farmers may be asked in the near future to reduce or mitigate these emissions. The manure management is becoming more-and-more a growing problem in livestock production facilities. The odor, pests and potential water and air pollution are issues that have to be addressed. In addition it is most important that the manure will be recognized AS a resource rather than a waste product (IPCC, 2007).
The most common housing system today in Israel consists of deep manure bedded packs that are being altered into "in sito" Cultivated Manure (ISCM). The ISCM form of housing can offer a reasonable solution to the welfare and environmental issue, e.g. the possible air and water pollution. We think that this housing system offers some solutions for the issues that influence cow welfare: housing system that offers comfortable, clean and dry bedding, and " in sito "
manure management that reduces gas and odor emissions.
According to past research the conditions that form in the ISCM e.g.- pH, temperature, DM, bacteria count and NH3 emission, might offer a suitable solution that agrees with cows welfare and reduce the greenhouse gases CH4 and N2O emissions. This method spares the need of additional bedding materials - hence less expenses. The cultivating system seems to initiate the compost process, and due to the daily routine, the process is kept aerobic and decreases CH4
and N2O emissions.
The hypothesis of the study- If cultivating the dairy farms bedding, made of cow's feces and urine, is aerating the bedding and drying it than it will decries the CH4 and N2O and increase the CO2 emission rates from the bedding and will improve animal's welfare.
