چکیده
Two hundred eighty-seven lactating Newsham sows and their litters were used to determine the effects of intensive indoor (n = 147) and intensive outdoor (n = 140) production systems on sow and litter productivity and behavior. All sows were of contemporary age and fed a completely balanced sorghum-based diet. Behavior data were collected by live observation on 40 sows and litters (20 indoor and 20 outdoor) using a 5-min scan sample over a 4-h period in the afternoon (1400 to 1800). The durations of lying (90.0 vs 72.1 ± 2.76% of time observed) and drinking (4.42 vs 1.41 ± 0.6% of time observed) were higher (P < 0.01) among indoor than among outdoor lactating sows. Nursing interval and feeding and sitting behaviors were not differ

متن کاملConsequences for Piglet Performance of Group Housing Lactating Sows at One, Two, or Three Weeks Post-Farrowing
Housing lactating sows with piglets in a multi-suckling pen from around 14 days post-farrowing is common practice in Swedish organic piglet production. However, nursing-suckling interaction is less frequent in multi-suckling pens than in individual farrowing pens, thus affecting piglet performance, e.g., piglet growth. Moreover, piglet mortality is higher in systems using multi-suckling pens. T...
متن کاملEffects of Dietary Lysine Supplementation on the Performance of Lactating Sows and Litter Piglets during Different Seasons
The effect of dietary lysine supplementation on the performance of crossbred lactating sows (n = 49, total 92 litters) and suckling piglets during the warm and cool seasons was studied. Sows were randomly allocated to one of two experimental diets, which were fed throughout a 28-day lactation period. Two diets were formulated based on corn-soybean meal with 6% wheat bran, containing 15% crude p...
متن کاملBehavior and performance of sows fed different levels of fiber and reared in individual cages or collective pens.
Sixteen pregnant sows were used. The experimental design was completely randomized with a 2x2 factorial scheme consisting of two housing systems (individual cages and collective pens) and two diets (low [2.67%] and high [13.14%] level of crude fiber). Physiological, behavioral, environmental, and hormonal parameters were studied. In addition, the following productive and reproductive parameters...
متن کاملObservations on the pre- and post-weaning behaviour of piglets reared in commercial indoor and outdoor environments
A number of behavioural problems are associated with weaning piglets including belly nosing, ear and tail biting, and low intake of solid food. These appear to be less pronounced in piglets reared on outdoor systems, which initially consume more solid food and show less belly nosing and aggression than comparable indoor-reared piglets. The objective of this study was to investigate how these di...
