Epidemiological studies comparing risk factors for subclinical mastitis (SM) in organic (OP) and conventional dairy production systems (CP) are lacking. In 60 OP and 60 CP farms, 970 cows were used to study risk factors for SM at 31 days postpartum.

The differentiation between inflammatory bowel disease (IBD) and food responsive diarrhea (FRD) is difficult and no objective markers are available. We postulated that patterns of selected key cytokines would help to objectively differentiate between

Plasma concentrations of insulin-like growth factor (IGF)-1 were examined in dogs suffering from food-responsive diarrhea (group FRD) or inflammatory bowel disease (group IBD) before and after treatment and compared with IGF-1 values in healthy dogs

The objectives of this study were to quantify the relationships of various definitions of feed utilization with both fertility and productive life. Intake and body measurement data were collected monthly on 970 cows in 11 tie-stall herds for 6 consec

The objectives of this study were to calculate the heritability of feed efficiency and residual feed intake, and examine the relationships between feed efficiency and other traits of productive and economic importance. Intake and body measurement dat

Summary This study compared productivity of dairy cows with different body weight (BW), but a constant ratio of maintenance to production requirements in their first lactation, in a pasture-based production system with spring calving. Two herds, Herd

Summary To study metabolic and endocrine adaptation of dairy cows to energy deficiency, blood metabolites and hormones were measured 37 ± 3 days after parturition during 24 h (group LE) and compared to levels in cows receiving high amounts of starch

We studied effects of protein intake at two protein-free energy intake levels on plasma glucose and insulin concentrations, urinary glucose excretion and on liver and intestinal fat content in milk-fed veal calves. Two experiments were performed at b

This study hypothesized that increased feeding frequency (FF) decreases problems with glucose homeostasis seen at high feeding levels (FL) in heavy veal calves. Effects of FF and FL on hormone and metabolite concentrations were studied in 15 heavy ve
