Investment levels in agricultural businesses specializing in dairy cattle production in Polish FADN regions were compared based on data for 2004-2016. The analysis included gross and net investments (variables FADN SE516 and SE521) and investment subsidies (variable SE406). The research shows that agricultural holdings specializing in dairy cattle farming in the years 2004-2016 in the FADN Wielkopolska and Śląsk region and in the region of Pomerania and Masuria have reached the level of gross investment per one farm on average annually higher than the average annual level of gross investment in Poland. Farms specializing in dairy cattle farming in the FADN regions of Mazowsze and Podlasie, as well as Małopolska and Pogórze have achieved a lower level of gross investment per farm than on average per year in Poland. The average level of net investment per one agricultural holding specializing in dairy cattle farming in the regions of FADN Wielkopolska and Śląsk, Pomorze and Mazury as well as Mazowsze and Podlasie was of a positive value, whereas in the Małopolska and Pogórze region it was negative. Studies have shown that agricultural farms specializing in dairy cattle farming in the Wielkopolska and Śląsk regions developed the fastest among all farms in Poland, while the fastest growing farms specializing in dairy cattle farming are found in the Małopolska and Pogórze regions.

SUMMARYOn a coastal farm in New South Wales where beef and dairy cattle production was carried on side-by-side, separate pasture plots were contaminated with eggs of Ostertagia ostertagi by calves from each production system in autumn, winter or spring. Successive groups of parasite-free tracer calves grazed on the plots for 14 days at 4-week intervals and were then killed for worm counts 14 days after removal from pasture. On all plots, the proportion of inhibited early 4th-stage larvae in tracer calves reached a maximum in spring, and was consistently and very significantly higher in calves which grazed plots contaminated with O. ostertagi of beef cattle origin. Factors which may be responsible for this difference between beef and dairy cattle populations of O. ostertagi are discussed.

A common problem of dairy cattle in all production systems and production directions is their reduced production life and therefore their reduced lifetime span. Among the main reasons of dairy cattle premature culling the problems related to reproduction, udder and legs are prevailing. The order of these reasons according to their significance is not the same in all dairy cattle populations and depends on production direction, level of production and specific technology of cattle breeding. There are also other reasons of culling but these three groups are the main ones. Due to frequency of their incidence, as well as economic damage which they can cause in dairy cattle production, today they must be taken into account when defining breeding goals for certain breeds and populations of cattle.

The aim of this study was to determine the socio-economic structures of dairy cattle farms and feed usage in dairy cattle sector in the Mediterranean Region provinces (Adana, Osmaniye, Mersin, Hatay, Kahramanmaraş) of Turkey. According to the results of the research, it was determined that the family sourced labour force was used at a higher rate than the foreign labour force during dairy cattle production activities. It was found that forage crops were produced in 62% of the farms where silage maize, alfalfa, barley and vetch covered the highest acreages, respectively. A large proportion of the enterprises was possessor of milking machines (85.81%). It was determined that, as the size of the farm increases, the roughage usage increases compared to concentrate feed.
