Examination of Effect of Season on Sustainability of Dairy Cattle Production
Abstract
Purpose of this study was to analyze effect of season on the sustainability of dairy cattle
production. In the study energy input/output analysis which is one of the criteria for sustainability is
conducted. Study was conducted at a commercial dairy farm, in Burdur Tefenni, which specialized
only in dairying and had 175 heads lactating cow during a production year which covered December
15, 2010 through December 15, 2011. At the first visit to the farm a file that recorded milk
production for each cow and number of lactating cows was formed and these records were recorded
for every day. Since the purpose of the study was to compare sustainability of dairy cattle production
in terms of season, seasons were classified as Winter (December to February), Spring (March to May),
Summer (June to August) and Autumn (September to November). Cultural energy used for feed for
cows was calculated by multiplying each ingredient with corresponding values of ingredients from
literature. Transportation energy was also included in the analysis. Total cultural energy expended was
similar for winter and spring, and it was higher from that of summer and autumn (P< 0.05). Cultural
energy expended for feed constituted more than half of the total cultural energy and was higher for
winter and spring (P< 0.05). Cultural energy expended per kg milk and energy efficiency for protein
were different for each season and were lowest for summer followed by winter, spring and autumn
(P< 0.05). Energy use efficiency differed for each season and was best for summer followed by winter,
spring and autumn (P< 0.05). As a result, cultural energy use efficiency differed among seasons and in
terms of sustainability this should be considered.
