Abstract

Objective: To examine systemic immunity in kittens, including transfer of maternal immunoglobulins from the queen to kittens, and subsequent decay of passively obtained immunoglobulins. Animals: 6 healthy queens and their 46 kittens. Procedure: Immunoglobulin concentrations were measured in serum, colostrum, and milk of queens and in their kittens' sera. Decay rate constants and half-lives of maternally derived immunoglobulins were determined. To determine intestinal absorption, foreign IgG was given to kittens at 6- to 8-hour intervals after birth, and bovine IgM was given to kittens at birth. Results: Immunoglobulin concentrations of milk and colostrum did not differ significantly after removal of milk fat. Mean IgG concentration was higher in colostrum/milk, whereas mean IgA and IgM concentrations were lower than those in the queens' serum. No IgG or IgA was detected in any of the precolostral serum samples obtained from kittens. Small amounts of IgM were present in the sera from 5 kittens at birth. Transferred IgG and IgA decreased rapidly with half-lives of 4.4 ± 3.57 and 1.93 ± 1.94 days, respectively. Serum IgM concentration increased irregularly during the first week of life, followed by a steady increase. Foreign IgG given up to 12 hours after birth was detected in kittens' serum, whereas IgG given at or after 16 hours was not found in any kitten's serum. Conclusions: Milk and colostral immunoglobulin concentrations did not differ significantly. The half-lives of maternally derived IgG and IgA in kittens were shorter than those reported in dogs. IgG given at or after 16 hours of life was not absorbed by neonatal kittens. Clinical Relevance: Queen's milk obtained anytime during lactation may be used as a replacement for colostrum as a source of antibodies for neonatal kittens. Kittens at risk for neonatal isoerythrolysis must only be removed from the queens during the first day of life. (Am J Vet Res 1996;57:1653–1658)

  • Colostrum is crucial for neonatal adaptation, not only as a source of immunity, but for the maturation of several organs; it is also an important energy source.

    “Colostrum is crucial for neonatal adaptation, not only as a source of immunity, but for the maturation of several organs; it is also an important energy source.”

    From Feline neonatology: From birth to commencement of weaning – what to know for successful management (2022) · cites this paper as [31]

    The Additional information section says that kittens acquire passive immunity from colostral immunoglobulins. Our copy does not say that colostrum matures several organs or serves as an important energy source; searches for organ maturation and energy or nutrient provision found no such passage. (LLM, conf=0.88)

  • High concentrations of maternal antibodies prevent the development of the neonatal endogenous immune response, with the maternal IgG half-life reported to be around 4.4 days in kittens.

    “The high concentrations of maternal antibodies, in fact, prevent the development of the neonatal endogenous immune response, with the maternal igG halflife reported to be around 4.4 days in kittens.”

    From Feline neonatology: From birth to commencement of weaning – what to know for successful management (2022) · cites this paper as [31]

    The passage labeled Abstract (page unavailable) reports an approximately 4.4-day half-life for maternally derived serum IgG in kittens. It suggests that colostral IgM would interfere with development of IgM-based immunity, but does not establish that high concentrations of maternal antibodies prevent the neonatal endogenous immune response generally; it also reports that kittens can synthesize IgM around birth.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
