[Relationship between body condition of dairy cows in the peripartum period and selected metabolic parameters in consideration of different breeds].

Objective: The results of this study describe the relationship between the body condition of dairy cows and selected metabolic parameters during the peri- and post-partum period with special consideration of 3 local dairy cow breed in Upper Bavaria and the Allgau.

Material And Methods: Three local dairy cattle breeds (Swiss Brown (BV), Simmental (FL), Holstein Friesian (HF)) were examined on 68 farms in southern Germany for 7 consecutive weeks. In dry cows as well as lactating cows (5.

[Use of milk haptoglobin concentration as an indicator in animal health monitoring of dairy cows].

Objective: The aim of the present study was to investigate relationships between elevated haptoglobin concentrations in milk and clinical as well as laboratory parameters in early lactating dairy cows. Furthermore, cut-off values should be identified for the differentiation of healthy and affected animals.

Material And Methods: 1462 dairy cows between 5.

Novel prediction models for hyperketonemia using bovine milk Fourier-transform infrared spectroscopy.

Metabolic diseases driven by negative energy balance in dairy cattle contribute to reduced milk production, increased disease incidence, culling, and death. Cow side tests for negative energy balance markers are available but are labor-intensive. Milk sample analysis using Fourier transform infrared spectroscopy (FTIR) allows for sampling numerous cows simultaneously.

[Methods for continuous body condition scoring in dairy herds - an Overview].

The body condition assessment methods Body Condition Scoring (BCS) and backfat thickness measurement are important methods to assess the energy status of a dairy cow in the dry period and early lactation. An extensive search of the scientific literature (online and analogue) was carried out for the presented review. Various keywords filtered important articles, which were entered into a literature management program and whose content was assigned to various categories, on which the review article is based.
