Management of the breeding chart (I)
A breeding chart would be like a type of computer without wires, screen or keyboard.

Feed palatability and voluntary feed intake in pigs
Piglets face a very stressful process at weaning and feed intake becomes one of the most limiting issues.
The effect of management strategies and parity on the behaviour and physiology of gestating sows housed in an electronic sow feeding system
Multiparous sows enter easily to the electronic feeders than primiparous without effects on feeder aggressions
Getting gilt integration right
With good returns on finished pigs, attractive cull sow prices and a contracting EU pig herd, many producers are building up their breeding herds again, some of which have been run at below optimum capacity for a long time.
Increased sow nutrition during midgestation affects muscle fiber development and meat quality, with no consequences on growth performance
Feeding pregnant sows amounts above the requirement during the period of secondary muscle fiber formation affected muscle fiber characteristics
Extra feed or lipid supplies 10 days prior to parturition and their consequences on farrowing and lactation performances
Extra lipid supplies before farrowing may improve piglet survival
Response of piglets weaned from sows fed diets supplemented with conjugated linoleic acid (CLA) to an Escherichia coli K88+ oral challenge
The use of sow dietary CLA supplementation through late gestation and lactation may improve piglet immunity and health status after weaning
Seasonal Infertility in Swine
In natural conditions, there are seasonal fluctuations of availability of food and the earliness or delay in the onset of breeding is related to food levels.
Thompson’s tip: Get cover for reduced fertility
Last year many herds suffered from reduced fertility in both summer and autumn. On many units this is a predictable effect says Paul Thompson, veterinary consultant to pig- breeding company, ACMC Ltd.
Feed intake in the multiparous lactating sow: Its relationship with reactivity during gestation and tryptophan status
High feed intake and low plasmatic Tryptophan levels during the lactation may be directly associated to sow reactivity
Effect of type and timing of oil supplements to sows during pregnancy on the growth performance and endocrine profile of low and normal birth weight offspring
The MUFA dietary supplementation during the first half of gestation may reduce the incidence of low birth weight
Dietary fiber for pregnant sows: Influence on sow physiology and performance during lactation
Higher feed intake during lactation let to improve sow and litter performance
The addition of ground wheat straw as fibre source in the gestation diet of sows and the effect on sow and litter performance
The dietary inclusion of wheat straw during the gestation phase improves sow and litter productivity.
Use of plant extracts in swine
The swine production industry has a growing interest in the use of essential oils. Essential oils are products of complex origin. They have antimicrobial and antioxidant effects, they stimulate appetite and intestinal secretions and they are even immunostimulants.
Peripartal feeding strategy with different n-6:n-3 ratios in sow: effect on gene expression in backfat white adipose tissue postpartum
The expression of the responsible genes for trapping, release and storage of fatty acids and glucose may be modulated by altering n-6:n-3 ratio of the diet in pregnant sows
