The objective of this study was to evaluate a genomic breeding scheme in small dairy cattle population that intermediate terms using both young bulls (YB) and progeny-tested (PB). This compared with conventional progeny testing program without use information and, as the extreme case, juvenile information, where all were used before available. structure, cost, plan parameters chosen reflect Danish Jersey population, being representative for population. consisted 68,000 registered cows....
The objective of the present study was to examine whether genomic selection females interacts with use reproductive technologies (RT) increase annual monetary genetic gain (AMGG). This tested using a factorial design 3 factors: (0 or 2,000 genotyped heifers per year), RT 50 donors selected at 14 mo age for producing 10 offspring), and 2 reliabilities prediction. In addition, different strategies how interact reliability prediction were investigated stochastic simulation by varying (1) number...
While benchmarking is already used for the assessment of performance gaps in cattle herd management and welfare concerns, its application to quantifying claw health relatively new. The goal here was establish a system Austrian dairy cattle. We electronically registered data cows from 512 herds documented by professional hoof trimmers, culling same herds, locomotion scores taken at regular milk testings 99 during 2020. Mean, median 10th, 25th, 75th, 90th percentiles incidences risk lameness,...
This study aimed to develop a tool detect mildly lame cows by combining already existing data from sensors, AMSs, and routinely recorded animal farm data. For this purpose, ten dairy farms were visited every 30–42 days January 2020 May 2021. Locomotion scores (LCS, one for nonlame five severely lame) body condition (BCS) assessed at each visit, resulting in total of 594 animals. A questionnaire about management husbandry was completed the inclusion potential risk factors. lameness incidence...
This study evaluated the voluntary and compulsory implementation of a bovine viral diarrhoea virus (BVDV) eradication programme in Austrian Federal State Styria, Austria, from an economic point view using ex-post assessment costs benefits (disease losses avoided). An net benefit (benefit:cost ratio, BCR = 1.18) was demonstrated during phase (January 1998–July 2004). The break-even reached 2003. If investments (August 2004–December 2016) were taken into account, loss (BCR 0.16) demonstrated....
Antimicrobial use in livestock production is an important contemporary issue, which of public interest worldwide. Antimicrobials are not freely available to Austrian farmers and can only be administered by veterinarians, or who trained members the Animal Health Service. Since 2015, veterinarians have been required law report antimicrobials dispensed for food-producing animals. The study presented here went further than statutory framework, collected data on those veterinarians.Seventeen...
Abstract. The objective of this study was to predict cows' body weight from size measurements and other animal data in the lactation dry periods. During whole year 2014, 6306 cows (on 167 commercial Austrian dairy farms) were weighed at each routine performance recording like heart girth (HG), belly (BG), condition score (BCS) recorded. Data on linear traits hip width (HW), stature, depth collected three times a year. Cows belonged genotypes Fleckvieh (and Red Holstein crosses), Holstein,...
Milk lactose content (LC) physiologically decreases with parity order in dairy cows, but also after udder health inflammation(s) and/or presence of elevated milk SCC subclinical cases. Therefore, the progressive decrease LC observed along cows' productive life can be attributed to a combination factors that altogether impair epithelial integrity, resulting weaker tight junctions, e.g., physiological aging epithelium, mechanical stress due milking, and experienced clinical or mastitis....
This study characterises diets used on-farm and examines nutrient feed intake (DMI) together with other animal specific traits (body weight, milk yield, body condition score). Data came from the project 'Efficient Cow' to develop efficiency for Austrian cattle breeding (161 farms, 6105 cows, one-year data collection). Most were grass silage- or maize silage-based. Nearly half (42.8%) of records separately fed concentrate partial mixed rations (PMR, 42.9%), 12.0% total (TMR). Feedstuffs...
This study reports on the exploration of temporal relationships between milk mid-infrared predicted biomarkers and lameness events. Lameness in dairy cows is an issue that can vary greatly severity concern for both producers consumers. Metabolic disorders are often associated with lameness. However, arise weeks or even months after metabolic disorder, making detection causality difficult. We already use technology to predict major components, such as fat protein, during routine recording...
Livestock farming is currently undergoing a digital revolution and becoming increasingly data-driven. Yet, such data often reside in disconnected silos making them impossible to leverage their full potential improve animal well-being. Here, we introduce precision livestock approach, bringing together information streams from variety of life domains dairy cattle study whether including more diverse sources improves the quality predictions for eight diseases using complex prediction algorithms...
