“…Anionic minerals did not prevent hypocalcaemia (Greghi et al, 2014). Total mixed ration particle size had a significant effect on incidence of displaced abomasums (Simoes et al, 2013). Lower serum alpha-tocopherol concentration was a potential early indicator for displaced abomasum in multiparous cows (Qu et al, 2013).…”

This opinion reviews information on small-scale dairy cow farming systems in Europe, including the impact of production diseases on welfare of cows, and proposes a methodology for welfare assessment in those systems. To address specific expectations of consumers that food be produced locally or regionally or maintaining acceptable animal welfare conditions, in addition to herd size, criteria to define farms as "non-conventional" were proposed. Several sources were investigated for identifying criteria for the description and categorisation of small-scale farms, including dairy umbrella organisations and literature. In addition to herd size (up to 75 cows), proposed criteria related to small-scale farming comprise the workforce source, input level, indigenous breed use and production type certification. To cover the large diversity of farming systems across Europe, it was proposed that farms meeting at least two of these criteria be considered non-conventional. To adapt the welfare assessment to small-scale farms, the same risk factors and welfare consequences, as measured by corresponding animalbased measures identified in previous opinions for intensive farming systems were considered to be also relevant for small-scale systems. In addition, factors related to resources provided on pasture (e.g. shelter), management of pasture (e.g. mixing herds) and management of the cows (e.g. use of local breeds) were considered more likely to be present in small-scale systems. An on-farm survey was run to collect data for welfare assessment from 124 European farms. The distribution of risk factors and animal-based measures varied across the full range in study farms and showed similar patterns in farms with different grazing systems (from no time to full year on pasture). The animal-based measures identified for intensive farming are well suited for application in smallscale dairy farms. Production disease impact on the individual animal's welfare state does not depend on herd size or farming system.

“…Factors which predispose animals to develop DA include breed (Holstein, Jersey, Guernsey; DOLL et al, 2009;ZERBIN et al, 2015), advanced parity (GEISHAUSER, 1995; Van WINDEN and KUIPER, 2003), twin pregnancy (PARDON et al, 2012), high pre-partum body condition score (CAMERON et al, 1998), negative energy balance in the pre-partum period (HEUER, 2000;CAMERON et al, 1998), and health conditions (endometritis, mastitis; . Additional predisposing factors include metabolic disorders (ketosis, metabolic alkalosis, hypocalcemia) which impact abomasal motility, leading to impaired abomasal emptying and increased gas accumulation (DOLL et al, 2009;MARTENS, 2000), as well as nutritional management factors such as low roughage and high concentrate diets (SHAVER, 1997; and corn silage particle size less than 8 mm (SIMÕES et al, 2013).…”

Risk factors for occurrence of displaced abomasum and their relation to nutritional management of Holstein dairy cattle

et al. 2017

The aim of the present study was to identify nutritional risk factors for the occurrence of displaced abomasum (DA) in Holstein dairy cattle raised in regions with highly variable nutritional management. Feeding program data were collected from 30 dairy farms throughout Kosovo via use of a standardized questionnaire, and an AgriNIR™ Analyser was used to analyze the nutrient composition of forage (hay, corn silage) fed to cattle on those farms. A diagnosis of DA was made via auscultation/percutation in the area of the last rib and hearing of a ping sound. Multivariate linear regression models were used to determine risk factors associated with the incidence of DA. The overall incidence of DA in this study was 4.9% (38 cases among 769 cows). Of cows diagnosed with DA, 81.6% (31/38) had left side DA and 18.4% (7/38) had right side DA. Nearly all DA occurred during the first month of the postpartum period -92.1% (35/38); only 7.9% (3/38) were observed in the pre-partum period. Risk factors that elevated the occurrence of DA included increased intake of concentrate feed after parturition (P<0.002), increased body condition score at calving (P<0.01), larger herd size (P<0.021), and increased daily consumption of corn silage in the pre-partum transition period (P<0.051). An increase in daily consumption of grass hay in the pre-partum transition period decreased (P<0.014) the incidence of DA. The results of this study are useful for developing enhanced nutritional management protocols to reduce the incidence of DA in Holstein dairy cattle.
