Application effect of goat raising on the slatted floor over biological fermentation bed
摘要
Abstract
To explore the advantages of goat raising on the slatted floor over biological fermentation bed compared with traditional large-scale breeding and farmer breeding in actual production,the experiment was to measure the fermentation temperature of different depth of fermentation beds with different thickness(30,50,60,80 cm)on the slatted floor over biological fermentation bed and to record the temperatures inside and outside the goat houses during varying time periods to determine the optimal thickness of the fermentation bed for biological fermentation bed goat breeding.Furthermore,the levels of NH3,H2S,and CO2 before and after renewing bedding materials were measured on the slatted floor over biological fermentation bed under the optimal fermentation bed thickness and in traditional large-scale goat breeding farms and farmer breeding modes,using the measurements of NH3,H2S,and CO2 levels measured in the spots of 500 meters away from the enclosure as a baseline control.The results showed that under the mode of goat breeding on the slatted floor over biological fermentation bed,the fermentation temperature in different depths of the thickness of the fermentation bedding of 30 cm was below 30.4℃,which was not significantly different from the ambient temperature inside and outside the goat house and did not reach the optimal growth temperature of 30-37℃for the fermentation strain of bacteria,leading to a poor fermentation efficiency.The fermentation temperature in different depths of the thickness of the fermentation bedding of 50 cm favored the middle layer between 25-35 cm for fermentation bacteria growth,while the surface and near-ground layers exhibited lower fermentation temperatures;the fermentation temperature in different depths of the thickness of the fermentation bedding of 60 cm was between 30-37℃,which was ideal for the growth and reproduction of beneficial fermentation bacteria and facilitated better degradation of goat feces and urine and thereby controlling livestock farming pollution.However,for the thickness of the fermentation bedding of 80 cm,the fermentation temperature in the middle layer was too high to be suitable for fermentation bacteria growth and the increased investment of bedding materials would incur higher costs and more daily management in practical production.Under the slatted floor over biological fermentation bed goat farming mode,the NH3 and H2S contents in the houses were lower than those in traditional large-scale farming and farmer farming(P<0.05 or P>0.05),and the CO2 concentration without the bedding renewing was higher than that in traditional large-scale goat farms(P>0.05)and farmer farming(P<0.05).However,the CO2 concentration with the bedding renewing was significantly higher than that in the farmer farming mode(P<0.05)and lower than that in traditional large-scale farming(P>0.05).It is recommended that a bedding thickness of 60 cm for the slatted floor over biological fermentation bed to ferment the bed material could effectively decompose goat manure and urine through fermentation bacteria,reduce the content of NH3 and H2S in the house and improve the air quality of raising environment,however,would not lower the content of CO2 in the goat shed.关键词
