Managing a 3-week batch system, weaning at the beginning of the week
This may be a good option when farrowings and litter control during the first days are the priority.

Effect of dietary CLA administration on fatty acid composition and lipogenic and lipolytic enzyme activities in suckling and weaned piglets
The concentration of fatty acids in subcutaneous fat and liver tissues of piglets 35 d after weaning is largely dependent on the CLA content of piglet diet rather than CLA enrichment of sow diet.
Managing a 3-week batch system
On small farms it is better to group tasks on specific days, leaving other days with less tasks in order to organize days off...
Work routines. Weaning
In the last decades the degree of technification and evolution of the productive systems at all levels has been constant.
Task organization: What day of the week should we wean? Several weanings per week
On large farms, it is common to wean more than once per week. This way, tasks can be homogenized throughout the week: each day will have a similar volume of work as the previous day.
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).
Longitudinal study of swine influenza virus infection in a farrow to finish farm
With the objective of determining the dynamic of influenza virus (SIV) infection in a closed cycle farm, investigators from CReSA (Spain) selected a complete batch of piglets weaned at 3 weeks (n=121) from a farm of sows that tested positive for SIV antibodies. They took nasal swabs and blood samples weekly, from week 3 to week 13, and then at weeks 15, 17, 20 and 24. On each visit to the farm, a clinical inspection of the sows was carried out.
Denmark - Pig slaughterings have dropped since 2004
Slaughterings in Denmark have dropped since 2004 and constituted 19.3 million in 2009 with a drastically increasing export of 7 million weaners.
The influence of soybean concentrate and fish meal on nursery pig performance
The objective of our study was to evaluate the effect of increasing levels of dietary soybean meal concentrate and fish meal on the performance of weanling pigs.
Evaluation of alternatives to increase weaning age
Without adding more space, the only way to accommodate an increase in weaning age is to decrease the breeding herd inventory.
Pork CRC nutrition research to pay producer dividends
Paying closer attention to nutrition in their pre and post weaning pigs promises to pay dividends for pork producers thanks to enhanced intestinal and immune development, survivability and performance.
Functional characterisation of a recombinant xylanase from Pichia pastoris and effect of the enzyme on nutrient digestibility in weaned pigs
The potential benefits of Xyn2 in the nutrition of weaned pigs should make it an alternative for industrial xylanase production.
Effect of replacing fishmeal with crystalline amino acids on growth performance of nursery pigs from 7 to 11 kg
A good amino acid balance by supplementing crystalline amino acids may substitute fishmeal from weanling diets without affecting performance.
In search of the ideal batch (2/2)
As we discovered in the last chapter, there are no “traditional” BM systems lasting over one week that allow for weaning at 28 days with a 5-week rotation time. However, breaking with the theoretical norms, we can wean at 28 days when working with batches every 5 weeks.
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...
Weaning in a shed
The current test is about weaning in sheds, with curtain separators in the nest.
