Subacute ruminal acidosis in Dutch dairy herds

Abstract

The prevalence of subacute ruminal acidosis (SARA) was determined in 197 dairy cows in 18 herds in the Dutch province of Friesland. Samples of rumen fluid were taken by rumenocentesis from between five and 19 animals on each farm and the pH of each sample was determined. The body condition of 139 of the cows was scored approximately three weeks before they calved and three weeks after they calved. The overall prevalence of SARA was 13.8 per cent, and the prevalence on individual farms ranged between 0 per cent (on seven of the farms) and 38 per cent (on one farm). The stage of lactation did not influence the prevalence of SARA but the cows with the condition lost more body condition over the calving period.

“…In practice by ruminocentesis manuplation, ruminal pH analysis was recommended for evaluation of SARA incidence in dairy farms (10). In the present study all 5 farms participated were employed within 24 cows per each.For the herd level, analysis of ruminal pH in a sample of 5-19 cows per herd might be of beneficial specifically at the postpartum period (10,19).…”

Most Turkish dairy cows are raised in small-medium sized farms [herd size ranges from 25 to 100 milking cows].All forages, protein supplements, minerals, vitamins and grains are thoroughly mixed in TMR, in which the cows were fed in the present study.…”

“…Dada la literatura anterior que conecta SARA a problemas de salud, es decir, enfermedades metabólicas de ganado lechero (9), la evidencia probada es relativamente débil. La SARA se ha asociado previamente para causar inflamación sistémica (7) y participar en la pérdida de BCS de la cowsprone afectada para estar en mal estado después del parto (10,11). Por otra parte, en lo que respecta a la SARA, la detección de la ruta fisiopatológica sigue siendo difícil porque a) la base de datos de las condiciones de campo sigue siendo insuficiente, b) se sabe menos sobre las consecuencias reales, la incidencia y la distribución regional de SARA en el campo.…”

“…metabolic diseases of dairy cattle (9), the evidenced proof is relatively weak. SARA has previously been linked to cause systemic inflammation (7) and to participate in BCS loss of affected cows prone to be in poorer condition post calving (10,11). On the other hand regarding SARA detection of pathophysiological route remains difficult because of a) database from field conditions remains insufficient, b)less is known about real consequences, incidence and regional distribution of SARA on the field (11).…”

“…Οι 22 από αυτές βρίσκονταν στην αρχή και οι υπόλοιπες 32 στο μέσο της γαλακτικής περιόδου (Tajik et al 2009). Τέλος, στην Ολλανδία, το 13,7% από το σύνολο των 196 αγελάδων που εξετάστηκαν από 18 εκτροφές εμφάνιζαν pH <5,5, ενώ το 16,8% είχε pH 5,6 -5,7 (Kleen et al 2009). Στην Ελλάδα έγινε παρακέντηση της ΜΚ σε 153 αγελάδες, από 12 εκτροφές, και ανευ ρέθηκε η νόσος σε 24 ζώα (15,7%).…”
