Piglets nutrition
At weaning, piglets are challenged by multiple sudden changes in their environment and diet. They are typically weaned between 3 to 4 weeks, when their digestive tract and immune system are still in development. As they need to adapt to new components in the diet, they are challenged with lower feed intake, digestive disorders and nutrient losses. To ensure optimal growth, piglets need (pre)starter diets formulated to meet their nutritional requirements and fully support their digestive health and immune system.
A successful nursery feeding program contains several components, but the most important are to: 1) match dietary nutrient levels and ingredients with weight and age of the nursery pig; 2) maximize feed intake, because newly weaned pigs are in an extremely energy deficient state and early intake helps maintain a healthy intestine; and 3) appropriately adjust pigs (based on age, weight, health status, etc.) to lower cost diets (usually grain-soybean meal diets) as quickly as possible after weaning to reduce total feed cost. The concepts are relatively simple and can be applied in a variety of situations around the world.
INTRODUCTION Organic acids have been used for decades in commercial compound feeds, mostly in feed preservation, where formic and propionic acids are particularly effective. In the European Union, these two organic acids and a number of others (lactic, citric, fumaric and sorbic acids) and their salts (e.g. calcium formate, calcium propionate) are used under the classification ‘feed...

Introduction With costs of pig production under increasing pressure, the nutrition of young pigs is of increasing interest, as this period is critical to the subsequent performance of the animals through to market. Optimising growth rate and feed efficiency at this time are therefore key requirements for success in today´s animal production systems. While antibiotics are available to assist in improving growth during...

Dear Users, This is an interesting forum from our Spanish community, generated by Ervin Poou from Guatemala: Dear friends, I take this opportunity to solicit comments about Weaning at 14 days as an alternative to increase the piglets produced per sow per year and to reduce mortality from crushing and diarrhea in the whelping box. Please if anyone has had experience in the subject I beg to share them. Thank you in advance! Ervin Poou ...

Weaning as currently practiced represents one of the most critical periods in the raising of pigs. It is characterized by a diminution in feed consumption, leading to a state of severe anorexia, an increased sensitivity to digestive problems or microbial infections, and a slow down of growth. The change in the nutrient substrate also brings with it major modifications in intestinal function, influencing nutrient utilization, metabolism or even protein synthesis....

(1) Can boars determine the number of piglets and if so how? (2) How long should it be between piglets arriving during farrowing? (3) What is the average weight of a piglet born? (4) How many hours does it take for the piglet to become aware of there surroundings? (5) How long does it take piglets to get to know their mum and her grunt.? (6) How many hours in a day do new borne piglets sleep? (7) How does a sow get them on to solid feed at 10 days and how does she know when to do...

The high-yielding sow faces many challenges in order to secure that as many piglets as possible are weaned at a satisfactory weaning weight. ● A large number of foetuses may result in prolonged farrowing ● Many and large piglets may result in skinny sows Prolonged farrowings Increasing litter sizes prolong the time of farrowing. A good and problem-free farrowing is among other things secured by...

Weight and backfat losses, during lactation, are reduced when lactating sows receive a feed containing Rovabio Excel, a NSP enzyme developed by Adisseo.
Six trials throughout the world, concerning more than 500 sows, with different genetics, different feed compositions, various ages at weaning, prove that on average weight loss can be reduced during lactation by more than 3 kg, and backfat thickness by 24 % from...

The genetic improvement has decreased drastically the synthesis and milk production in lactating sows; the technicians have had to resort to the use of replacement milk to piglets during lactation. This problem can be solved applying three improvements:
1-Concentrating nutrients in the diet of lactating
2- Stimulating feed intake during lactation (for example using the meal six times per day, use of flavourings, act.)
3-Using a micronized powder fat to the liver bypass based in...

In his presentation, first of all Jean Le Dividich referred to the piglet´s characteristics after birth: - It is born with a very low energy reserve: very thin (1 to 2% of adipose tissue, without "brown" fat) - No immune protection (agammaglobulinemia) due to the lack of antibody permeability of the sow's epitheliochorial placenta. These low energy reserves...

Gaining popularity in Western Europe, but apparantly already used for many years in the U.S. is the use of automated systems for milk supplementation to suckling piglets in the farrowing room. I would like to know from people who are using this kind of system what their experiences are. How much milk do the piglets consume, at what cost, etcetera. Are you not using this kind of system? Then i would like to know what you think about milk supplementation. Thank you in...

Dear Users,
This is an interesting forum from our Spanish community, generated by Fabián Ruiz Herrera from Perú:
Is it proper the use of iron dextran at doses of 1 mL at 3 days old and then a second dose at 10 days with equal doses for the prevention of iron deficiency anemia (both associated with vitamin B12)? Or are there other additional doses? Or another schedule?
Best Regards.

Birth to weaning is a high-risk period for piglets. The present paper reports the efficacy of supplementing the sows diet with Stimune® (specific fatty acids) to increase the survival of piglets by enriching the colostrum and stimulating the immune system of piglets. A trial involving 70 sows and their offspring compared two groups : a control group without marine fatty acids and a group supplemented with 50 g/day/sow (top feeding) for the 15 days before farrowing and during the first 15...

If sows are heat-stressed their daily feed intake decreases to decrease heat production. The reduced feed intake can result in increased tissue loss from the sow, lower piglet weaning weights, and possibly higher mortality rates (Spencer et al., 2003). Early weaning and use of milk replacer may alleviate these effects (Ratliff et al., 2004), and milk replacer may also decrease piglet weight variation at weaning (Wolter et al., 2002). Spencer et al. (2003) researched the effects of...

Weaning is one of the most stressful times in a pig’s life. Not only does it mean big changes in social, thermal and physical environment, but it also means a huge change in diet form and composition. As a result, piglets often suffer from poor nutrient intakes and performance during this initial period following weaning, until they are able to make the necessary adjustments. To reduce stress during this period, many different techniques, including the development of special pre and...

The two to three weeks after weaning are a difficult period in the piglet’s life. During this time the piglet is exposed to tremendous stress mainly due to an abrupt change from milk to a dry, vegetable-based diet. This change in diet results in a low feed intake and leads to changes in digestion and intestinal morphology. Shortening of the intestinal villi and deepening of the crypts have been observed in piglets post-weaning (Nabuurs et al., 1993). Those changes in intestinal...
