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...
Maternal breeds for sows have been bred high prolificacy during recent decades. Although large litters may be beneficial economic efficiency, pre-weaning mortality is increased. Thus, focus should instead put on new traits such as piglet vitality (PV). Until now, no validated scoring scheme exists, which feasible to applied routine on-farm trait recording. The objective of this study was validate a four-point (1 = low 4 vitality) by farmers based and estimate genetic parameters. A linear...
In the domain of precision livestock farming, integration diverse data sources is crucial for advancing sustainability and evaluating implications farm management practices on cow health. Addressing challenge heterogeneity diversity, we propose a key-feature-based clustering method. This approach, merging knowledge-driven feature selection with unsupervised machine learning, enables systematic investigation effects health by forming distinct clusters analysis. Utilizing from 3,284 Austrian...
Data cleaning is a core process when it comes to using data from dairy sensor technologies. This article presents guidelines for with specific focus on herd management and breeding applications. Prior any steps, context purpose of the use must be considered. Recommendations are provided in five distinct steps: 1) validate merging process, 2) get know data, 3) check completeness 4) evaluate plausibility measures detect outliers, 5) technology related noise. Whenever necessary, recommendations...
Gastric ulcerations in finishing pigs can cause growth restriction, sudden death and contamination of the carcass by invading microorganisms. The aim study was to compare macroscopic histological findings stomach mucosa fattening kept at 1m²/pig provided with long straw (10 groups, 113 pigs) a control group 0.7m²/pig without (11 120 pigs). At slaughter, gastric health assessed scoring 233 stomachs ranging from 0 (no alteration mucosa) 3 (ulceration). scores were correlated organ alterations,...
Selection for feet and leg traits can increase longevity as well several performance in sows.Moreover, good quality contributes improving animal welfare not only sows, but also piglets.Sows with problems have a higher risk of crushing their piglets when lying down.Therefore, scoring scheme was derived applied by trained assessors.Furthermore, piglet mortality rate recorded.Genetic parameters breeding values were estimated the effect on investigated.Data 993 Large White 299 Landrace sows 23...
Due to economic and animal welfare related issues, the Austrian pig breeding organisations revised their programs. Members of organisations, breeders academic staff were involved in a participatory process from beginning. In several meetings workshops, 11 new fitness traits regarding maternal abilities piglet vitality gathered. Therefore, asked propose important sow ability as well vitality. Calm behaviour, milk performance conformation mentioned most for suckling high birth weight growth...
Low-cost sensors are extensively used in numerous Internet of Things (IoT) applications to measure relevant physical processes. Today, processing context data is increasingly done by proprietary algorithms tuned a specific use-case, e.g., sensor measuring activity intensity cow. Readings from these may be subject distribution shifts, which challenge robustness models using readings. In this paper, we propose new framework, leverages co-dependency between quality and model detect performance...
The aim of this study was to investigate the impact reduced stocking density in combination with provision additional enrichment material on pig welfare on-farm. On three growing-finishing farms Austria, total 974, 413, and 70 pigs were kept at 1 m2/pig straw or hay a rack as (improved pens, IP; n = 6-38 pens per farm) complying minimum legal requirements 0.7 (control CP; 6-37 farm). Behavior well skin, tail ear lesions soiling assessed beginning middle fattening period, while performance...
