Seasonal impacts on lactation curve course in dairy cows = Sezonski vpliv na potek laktacijske krivulje pri kravah molznicahOrešnik, Andrej, 1943-2016 ; Logar, AlojzData utilised in this study were obtained from a herd on a large dairy farm (428 Black and White cows) collected by official AP control. Average milk yield of cows in 1997 was 6 382 kg of milk with ... 3.82 % of fat and 3.35 % of protein in standard lactation. Feeding strategy on the farm was similar to circumstances on manz other farms in Slovenia: pasture, maize silage, hay, mineral-vitamin mixture and adequate feeding of concentrates in grazing period and grass silage, maize silage, hay and adequate feeding of mineral-vitamin mixture and concentrates in housing period (open free stall bedded with straw). There existed significant differences in milk yield of cows that calved in different seasons or months of the year. The average lactation curve course indicated a very small rise in milk yield in the first period of lactation and later on a satisfactory milk persistency. Between seasons existed differences in lactation curve course, where a decline in milk yield in the fourth month after calving in autumn calving cows was significant and clearly worsened milk persistency in all cows in summer months. Cows that calved in March and September attained the same milk yield in standard lactation (6 345 kg and 6 371 kg) with quite different lactation curve course. Out of the results it can be concluded that differences in milk yield due to seasonal impacts can be explained by differences in lactation curve course. It is likely that factors other than only temperature (nutrition) have to be involved in interpretations of estimated seasonal effects on milk production.Vir: Prireja mesa in mleka v prihodnosti = Meat and milk production in the future (Str. 143-149)Vrsta gradiva - prispevek na konferenciLeto - 2001Jezik - angleškiCOBISS.SI-ID - 1193864
