Effect of dietary supplementation of n-3 fatty acids and elevated concentrations of dietary protein on the performance of sows
Dietary supplementation of n-3 fatty acids during lactation improved the growth of nursing piglets.

Dose-response effect of fish oil substitution in parturition feed on erythrocyte membrane characteristics and sow performance
Osmotic resistance of erythrocytes was not altered by increasing amounts of n-3 PUFA, whereas oxidative stability of erythrocytes, as well as oxidative parameters in plasma, were affected.
Does group housing increase the risk of reproduction problems in French sow herds?
The aim of this study was to investigate reproductive performance and possible reproductive problems (late estrus, infertility, reasons for culling) in herds with either group‐housed or individually housed pregnant sows. In a second analysis, we evaluated the effects of different group housing systems.
What day of the week should we wean?
A large part of the work on a swine farm can be divided into 3 key tasks: weaning, mating and farrowing. The day chosen for weaning determines the other two tasks; first, the matings, and then, as a consequence, the farrowings (the 2 ‘great events’ of which productivity of a farm depends on).
Mating guidelines (III)
In the last chapter we examined mating guidelines that came rather close to being ideal, given that they achieve the following objectives: At least one mating should be adjusted to meet the ideal time and achieve the first objective with the least number of matings.
Denmark - Expectations of 2013
In 2001, the EU decided that all sows must be housed loose by 2013, giving the pig producers 12 years to adapt. In Denmark, this legislation was introduced in 1998. To form an impression of the situation in Denmark, Hatting-KS, the Danish Pig Producers’ Association and Pig Research
Centre forwarded questionnaires to all Danish sow farmers with more than 100 sows asking them about their expectations of 2013.
Mating guidelines (II)
The ideal mating guideline should follow 2 objectives: At least one mating should be adjusted to meet the ideal time and achieve the first objective with the least number of matings.
Reproductive performance of sows is affected by the dietary omega‐6 to omega‐3 fatty acid ratio
An experiment was conducted to determine the effects of the omega‐6 (n‐6) to omega‐3 (n‐3) fatty acid ratio in sow diets on reproductive performance and immunoglobulin profiles in sow colostrum and piglet serum.
Mating guidelines (I)
As mentioned in the previous chapter, theoretically, the ideal mating time is around 10-12 hours before ovulation.
Phenotypic and Genetic Correlations between Gilt Estrus, Puberty, Growth, Composition, and Structural Conformation Traits with First Litter Reproductive Measures
The objective was to estimate correlations of gilt estrus, puberty, growth, composition, and structural conformation traits with first litter reproductive measures.
Pork CRC: Hot news on seasonal infertility in pigs
Although eliminating the costly problem of seasonal infertility in pigs is probably beyond us, considerable research, supported by Australia’s Pork Cooperative Research Centre (CRC), has been pulled together into how best to combat it
Ideal mating time
The optimal fertilization of a sow depends on several factors, among them, mating in a specific moment of the oestrus.
Planning weaning (II): How many sows should I wean?
As mentioned in the first chapter of planning weaning, after deciding which sows are going to be weaned, on weaning day we must take into account several factors...
USA - OLCSB swine committee recommends stall-free by 2025
After several hours of intense discussion and deliberation, the swine subcommittee for the Ohio Livestock Care Standards Board decided to remove an exemption in its recommendations, that would have allowed existing swine producers to expand their stall-based facilities beyond 2025.
Effects of fibre and floor space allowance on group kept dry sow well-being
Sow welfare may be directly related with floor space allowance and dietary fibre.
Linseed meal during early pregnancy increases litter size in pigs
To determine how feeding linseed meal (LSM) during gestation influences litter size, placental weight, and piglet growth, sows (n = 30) received a phytoestrogen-free Control diet throughout gestation; 12.5% LSM diet throughout gestation (LSM114); or 12.5% LSM diet from day 1 to day 15 of gestation and control diet until parturition (LSM15).
