Lundborg, K. 2004. Housing, management and health in Swedish dairy calves. Doctor’s dissertation. ISSN 1401-6257, ISBN 91-576-6656-3 This thesis discusses the results of an observational study conducted in dairy herds in the south-western Sweden and a questionnaire survey of dairy herds done throughout Sweden. In the observational study the health of 3 081 heifer calves in 122 dairy herds was m...

We developed an advisory tool addressing 10 critical areas of calf and heifer management, including calving management, care to newborn calves and painful procedures, colostrum management, cow-calf separation, calf feeding, weaning, calf housing, heifer feeding, heifer housing, and general monitoring. Targets and indicators for each critical area were validated by a panel of experts and maximum...

The purpose of this study was to investigate the effect of maternal inbreeding on incidence of twinning,dystocia and stillbirth in Holstein cows of Iran. Calving records from March 2000 to April 2009 comprisingof 365,021 calvings on 153,802 cows from 86 dairy herds were used. The mean level of inbreeding was0.7%, less than 37% of all animals were inbred, and a small proportion (3.45%) of inbree...

Improving health and welfare outcomes for replacement surplus dairy calves is important the sustainability of industry. Dairy farmers veterinarians hold expertise in calf management have valuable perspectives on how to practically motivate improvements. The objective this study was determine strategies that could improve care receive farms from perspective their herd veterinarians. Two veterina...

calving records from april 1998 to september 2006 comprising 104,572 calving events from 16 dairy herds of iran were used to analyze the potential effect of dystocia on calf stillbirth and productive traits in iranian holsteins. statistical analyses of production traits were performed using a linear mixed model procedure. also, a logistic regression model was constructed to analyze the effect o...

An alternative protein ingredient based on spray-dried, hydrolyzed red blood cells was evaluated in calf milk replacers. Two experiments were conducted to determine the value of the ingredient on intake, growth, and feed efficiency in dairy calves. In experiment 1, Holstein bull calves (n = 120) were fed calf milk replacer containing 0, 11, 22, or 43% of crude protein as spray dried hydrolyzed ...

Abstract In this research communication we describe the performance of dairy cow−calf pairs in two cow-driven CCC-systems differing cows' access to calves through computer-controlled gates (smart gates, SG). We investigated machine milk yield automatic milking system (AMS), calf growth, and intake supplemental concentrate. Two groups each with four cow-calf were housed a cow area, creep meeting...

In dairy calves kept in pens, lack of sufficient space may inhibit the performance of play behaviour. The present study investigated, firstly, if an increase in space allowance increases the occurrence of play behaviour, and secondly, if calves kept at a low space allowance perform more locomotor play when released individually in a large novel area. A total of 96 dairy calves in six repetition...

Abstract Research is needed on how technology can facilitate cow?calf contact (CCC). This research communication describes the behaviour of dairy pairs in two cow-driven CCC-systems differing cows' access to calves through computer-controlled gates (smart gates, SG). Specifically, cow traffic SG when visiting their calves, allogrooming, suckling and cross-suckling, eating resting finally vocal ...

There is an interest in alternative rearing systems that allow for prolonged cow-calf contact (CCC). Yet, a better understanding of cows’ affiliative behaviour those needed. We evaluated the effect type CCC on calf-directed dairy cows. Cows were permitted to have either: i) partial (PC) with their calf; calves housed pen adjacent cow area allowing limited physical initiative dam but no suckling...
