Abstract

SARA je metabolički poremećaj kojeg je često puta teško prepoznati u stadu. Najvažniji etiološki čimbenik u razvoju SARA-e, je prehrana s povišenim sadržajem lako probavljivih ugljikohidrata, uz istovremeno nedovoljan unos grube vlaknine što za posljedicu ima pad pH buragovog sadržaja ispod 5.5. Patofiziologija je kompleksna, a klinički znakovi razvijaju se tjednim i mjesecima. Pad mliječnosti i poremećeno opće zdravstveno stanje životinje jedni su od glavnih problema koji se javljaju kao posljedica SARA-e. Pošto ne postoji točno određena metoda dijagnostike, praćenjem pH-vrijednosti buraga, razine mliječne masti i općeg zdravstvenog stanja stada mogu se dobit podaci koji bi upućivali na SARA-u. Preventivne mjere usmjerene su na pravilnu pripremu obroka i sprečavanje naglog prejedanja dok zdravstveno stanje, dobrobit, produktivnost i utjecaj na okoliš uvelike ovise o menadžmentu SARA-e u mliječnim stadima.

Abstract (english)

SARA is a metabolic disorder that is often difficult to recognize in a herd. The most important ethiological factor in development of SARA are meals with excessive amount of easy fermentable carbohydrates and low intake of forage, wich results in rumen pH values belowe 5.5. The patophysiology of it is complex, and the symptoms develop for weeks and months. Some of the main issues which develop as a consequence of SARA are general health disorders and a drop in average milk yield of the animal.
As a specific diagnostic method does not exist, by assessment of the pH value of the rumen, level of milk fat and general health condition of a herd, it is possible to collect data which could point to SARA. Preventive care is focused on proper meal preparation and prevention of sudden overeating while health condition, well-being, productivity and environmental impact greatly depend on managing SARA in dairy herds.
