In the world of piglet rearing, colostrum isn’t just the first meal—it’s of vital importance. This initial milk flow from the sow, produced within the first 24 hours post-farrowing, is a powerhouse of nutrients and antibodies essential for piglet survival and development.
A sow typically produces between 1.9 to 5.3 kg of colostrum, regardless of litter size. This means that in larger litters, each piglet’s share decreases, increasing competition and the risk of inadequate intake .
Sows in their second and third parities often produce more colostrum compared to gilts or older sows . Monitoring sow age and health can help predict and manage colostrum availability.
Piglets should consume at least 160–170 g of colostrum per kilogram of body weight to ensure survival and optimal development . Insufficient intake is linked to higher mortality rates and weaker immune systems.
Colostrum is richer in crude protein and immunoglobulins but lower in fat compared to regular sow milk . This unique composition is tailored to meet the immediate needs of newborn piglets.
The concentration of immunoglobulin G (IgG) in colostrum decreases significantly after birth—dropping to 50–65% within 6 hours and to 10–15% after 24 hours . Early feeding is essential to maximize antibody absorption.
Piglets’ intestines are most permeable to antibodies immediately after birth, with absorption capacity diminishing after 24 hours . Delays in colostrum intake can compromise immune protection.
Unlike humans, piglets don’t receive antibodies in utero. Colostrum is their sole source of passive immunity, making its timely intake critical for disease resistance.
Sows begin producing colostrum before farrowing. Proper nutrition and management during this period can enhance colostrum quality and quantity.
In large litters, temporarily separating stronger piglets allows weaker ones better access to colostrum, ensuring more uniform intake across the litter.
Adequate colostrum intake not only boosts immediate survival but also influences long-term health, growth, and productivity of piglets.
