The evaluation of feeding lactating sows on grams of lysine compared to percent of lysine in the diet
Formulating a sow diet based on percent lysine is only effective when total feed intake is known.

Playing and fighting by piglets around weaning on farms, employing individual or group housing of lactating sows
We assessed how piglets play, fighting and biting behaviour before and after weaning were affected by the housing system and weaning age as well as how the three behaviours are related to each other and piglet post-weaning weight gain.
Dietary protein intake and stage of lactation differentially modulate amino acid transporter mRNA abundance in porcine mammary tissue
Mammary gene expression of AA transporter is not affected by dietary protein intake.
Hormone management (II)
When the sow is pregnant, the corpus luteum remains and continues to produce progesterone. While the levels of progesterone are high the sow does not become in heat and maintains gestation.

Skin disease is one of the most difficult areas to assess clinically and on gross pathology.
Piglet colostrum intake
Colostrum offers 3 essential properties to the piglet: very useful energy source (vital for generating movement and avoiding temperature loss), immune supply (protects against germs that the piglet begins to come into contact with) and natural growth factors (complete the maturity of the piglet).
Piglets chomping on their mother
A litter of piglets in Thailand. One piglet struggles to get a teat.
Oral administration recombinant porcine epidermal growth factor enhances the jejunal digestive enzyme genes expression and activity of early-weaned piglets
Epidermal growth factor supplementation of piglet diets may stimulate intestinal piglet development and maturation at weaning
What is the best age for weaning piglets? (2/3)
Normally the productivity of the sow is valued for the number of litters/sow/year multiplied by the number of weaned piglets per litter.
Effect of dietary alpine butter rich in conjugated linoleic acid on milk fat composition of lactating sows
Milk fat content in lactating sows was not affected by the dietary supplementation of conjugated linoleic acid however, milk conjugated linoleic acid content is increased
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
Effect of dietary fat or starch supply during gestation and/or lactation on the performance of sow, piglets' survival and on the performance of progeny after weaning
Piglet survival at farrowing and at weaning may be improved by sow dietary energy supply during gestation and lactation
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
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
Feeding of lactating sows
The sow’s intake is affected by the interaction of different factors, not just nutritional but also those connected with the animal, handling or system of production.
Whey Products in piglet diets
A large body of research data exists on the response of pigs to whey. Good quality whey protein contains all the protective components of milk protein.
