Canine and feline colostrum.

Area of Science:

• Veterinary Neonatology
• Immunology
• Animal Reproduction

Background:

• Puppy and kitten survival hinges on colostrum, a critical mammary secretion rich in nutrients and immunoglobulins.
• Colostrum supports digestive tract maturation and provides crucial immune factors like IgA, lysozyme, and lactoferrin.

Purpose of the Study:

• To highlight the importance of colostrum for neonatal survival in puppies and kittens.
• To detail the composition and immune functions of colostrum compared to mature milk.

Main Methods:

• Review of existing literature on canine and feline colostrum.
• Analysis of colostrum composition (immunoglobulins, energy) and its impact on neonatal health.

Main Results:

• Colostrum contains significantly higher immunoglobulin G (IgG) concentrations than milk.
• Immune quality of colostrum varies, independent of maternal factors; IgG absorption is time-limited (12-16 hours post-birth).
• Colostrum's energy content is comparable to milk, influenced by fat and maternal breed size.

Conclusions:

• Early and sufficient colostrum intake is paramount for neonatal immune transfer and survival.
• Adequate energetic supply from colostrum impacts neonatal mortality risk.
• Colostrum is the first essential care for newborn puppies and kittens, influencing their long-term health.
