The aim of the study was to analyse the genetic background of different traits to characterise the maternal behaviour of sows and to evaluate the relationship to different causes of piglet losses – increasing piglet survival due to higher maternal

In spite of the improvement in management and the breeding goal of increasing the number of piglets born alive, piglet mortality is still a substantial problem in pig breeding. The objective of the first part of the study was to estimate genetic para

The aim of the study was to analyse the influence on tail-biting in undocked pigs during the rearing period of crude fibre in piglets' rations. All pigs were fed the same pre-starter until weaning. The study comprised two trials with four experimenta

The aim of this study was to reveal the effects of raw material provision on tail-biting outbreaks in long-tailed pigs. Two different substrates, dried corn silage (SG, n=245) and alfalfa hay (AG, n=245) were provided for the pigs twice per day from
The study was conducted to investigate the influence of systematic effects on fertility traits in Swiss Brown cows. Days to first service (DFS), days open (DO), calving interval (CI), non-return rate 90 (NRR90), and conception rate to first service (

Increased herd sizes and narrowed income margins are common characteristics of modern swine farming. Therefore good management is becoming more and more important for the economic results. The paper describes a computer-based weak-point analysis of i

There is considerable variation in recommendations for optimum tryptophan (Trp):lysine (Lys) ratio in diets of starter pigs up to 35 kg body weight (BW) which may partly be due to differences in the composition of experimental diets, the experimental

In this study, a response test towards a stockperson was evaluated for improved maternal behaviour and increased piglet survival. Records were available from 638 German Landrace gilts with 860 observations tested for the response to an observer in th

Statistical control charts are effective tools to reveal changes in a production process. The CUSUM (cumulative sum) and the EWMA (exponentially weighted moving average) control chart are used to detect small deviations in a process. Data from two so
