Although it is still most common to rear dairy calves separately from adult cattle, the interest in prolonged contact between and lactating cows during early life increasing. Previous research has documented positive effects of cow-calf (CCC) on for example calf growth udder health suckled cows, but also negative such as increased separation distress reduced weight gains after weaning. The aim this study was use information European farms with identify innovative solutions challenges CCC...
The detection of quantitative trait loci has accelerated with recent developments in genomics. introduction genomic selection combination sequencing efforts made a large amount genotypic data available. Functional traits such as fertility and calving have been included routine estimation breeding values making quantities phenotypic available for these traits. This was used to investigate the genetics underlying identify potentially causative regions variants. We performed genome-wide...
The occurrence of cervical cancer is often linked to a previous infection with human papillomavirus (HPV). In order detect HPV infections in smears, broad range tests can be used. This study compares the two hybridisation-based DNA-microarray systems “HPV 3.5 LCD-Array” (Chipron GmbH) and “PapilloCheck®” (Greiner Bio-One GmbH), based on their ability differentiate 42 different smears. PapilloCheck® individually identify 24 types, whereas LCD-Array among 32 genotypes. However, both include...
This research paper compares fertility traits, health indicators and management routines of Swiss dairy farms characterized by short vs. long productive lifespans (SPL LPL). We evaluated whether a longer lifespan will result in poorer cow based on herdbook data from breeders associations (n = 142), farm questionnaire 67), veterinary treatment 64) obtained during visits 30). Dairy were selected such way that they contrasted terms length lifespan, but representative the sector. Fertility...
Body condition scoring is a common tool to assess the subcutaneous fat reserves of dairy cows. Because its subjectivity, which causes limits in repeatability, it often discussed controversially. Aim current study was evaluate impact considering cows overall appearance on process and validity results. Therefore, two different methods reveal body scores (BCS), 'independent BCS' (iBCS) 'dependent (dBCS), were used 1111 Swiss Brown Cattle. The iBCS dBCS systems both working with same flowchart...
Gastrointestinal nematodes (GIN) severely affect small ruminant production worldwide. Increasing problems of anthelmintic resistance have given strong impetus to the search for alternative strategies control GIN. Selection animals with an enhanced GIN has been shown be successful in sheep. In goats, corresponding information is comparatively poor. Therefore, present study was designed provide reliable data on heritabilities and genetic correlations between phenotypic traits linked milk yield...
This study aimed to identify organic dairy major farm types (MFTs) in seven European countries, describe these MFTs an open research database and assess central characteristics of the MFTs. was conducted a three-step procedure including (1) Identification countries: Austria, Switzerland, Germany, Denmark, Lithuania, Poland Sweden, based on existing data from databases consultations with experts within respective fields knowledge; (2) Collection characteristics, management procedures,...
In contrast to natural and historical diets of wild domesticated ruminants, the diversity plant species is limited in modern dairy cows. Are "production diseases" linked this? We conducted a trial test effects multicomponent herbal feed additive (HFA) on health, performance fertility traits. A dose-finding study (DF) with 62 cows 11 commercial farms compared low (50 g) high (100 dose HFA (HFA-50, HFA-100) placebo (PL). subsequent field (FT) 280 30 farms, HFA-100 was PL. Cows were randomly...
Data from breeder hens and chicks are particularly critical for the development of vitamin B2 recommendations organic poultry. To test safe thresholds supplementation, 100 (Hubbard JA 57 K) ten cockerels were allocated to housing groups, with each receiving supplementation either 4.0 (treatment CON) or 2.5 mg RED) riboflavin per kg feed. After 15 weeks experimental feeding, 256 eggs incubated. From hatched S757), 192 four treatments based on their parents' treatment (CON- RED-) own (-CON)...
Although the use of local breeds is recommended by organic regulations, breed comparisons performed under production conditions with similar intensities are scarce. Therefore, we compared data and widely used Holstein dairy cattle from 2011 to 2015 regarding production, fertility health German Swedish farms management within country. In Germany, energy-corrected total milk yield tended be lower in Original Angler Cattle (AAZ, 5193 kg) modern Friesian (HO, 5620 kg), but AAZ showed higher fat...

Postweaning diarrhoea (PWD) due to Escherichia coli is an economically important disease in pig production. In this placebo-controlled study performed Switzerland, the effects of oral supplementation Allium sativum L. (garlic, AS) on performance (bodyweight (BW) and daily weight gain (DWG)) health (body condition clinical score) were investigated postweaning piglets. Piglets (n=600) randomly assigned treatment groups (placebo, AS or colistin) observed from birth until three weeks...
1. Ascarids (Ascaridia galli and Heterakis spp.) are highly prevalent in free-range laying hens. Ascarid eggs survive for long periods soil, one preventive measure is to add litter material areas close the henhouse. In this study, recovery rates of ascarid from three common materials, namely pea gravel, beech (Fagus sylvatica) spruce (Picea abies) wood chips were compared soil.2. Materials mixed with faeces containing 1,408 per g faeces, placed plastic fruit boxes exposed natural weather...
