About This Product:

Impact Colostrum Supplement is made from powdered bovine colostrum with added lactalbumin (whey protein),omega-3 and omega-6 fatty acids, vitamins and minerals.

  • Colostrum contains high levels of immunoglobulins and antibacterials such as lactoferrin, lysozyme, and lactoperoxidase that provide immunity and intestinal protection to young animals.

  • Feed Impact to newborn eutherians in the first 48 hours and to marsupials until weaning.

  • Available in 25g, 50g, 250g, and 500g resealable plastic jars.

About Colostrum

  • Colostrum is the first milk produced by a mother after birth. It is high in protein, much of which is immunoglobulins -- a group of proteins with antibody activity. Antibodies are produced in response to infection by micro-organisms.

  • The three main classes of immunoglobulins are Immunoglobulin A (IgA), Immunoglobulin G (IgG) and Immunoglobulin M (IgM). A few mammals -- such as rabbits, mice and humans -- are born with maternal transplacental IgG, although not IgA or IgM. Most species are born, however, totally devoid of immunity and must, therefore, acquire their initial immunoglobulins from colostrum. For the immunoglobulins in colostrum to function as systemic antibodies, they must first be absorbed from the intestine in an unaltered state.

  • Colostrum contains other proteins such as lactoferrin, lactoperoxidase and lysozyme that also have antibacterial characteristics. These proteins are usually found in higher concentrations in colostrum and early lactation milk. Importantly, they act to inhibit pathogenic micro-organisms from colonizing in the infant's intestine. Together with low levels of immunoglobulins, these proteins may remain in the milk throughout lactation.

    • Lactoferrin binds iron and facilitates its uptake from the intestine. This inhibits a wide range of micro-organisms that require iron for growth. When lactoferrin is hydrolysed by gastric enzymes, it releases a peptide that is highly bactericidal to several species of pathogenic organisms.

    • Lactoperoxidase is bacteriostatic to a wide range of bacteria when in the presence of thiocyanate and hydrogen peroxide generating enzymes. It denatures bacterial proteins by halogenation with hydrogen peroxide and halogens.

    • Lysozyme is bactericidal to many bacteria. Lysozyme hydrolyses the muramic acid in the cell wall thus causing the cell to lyse.  Lysozyme also acts in concert with IgA, lactoperoxidase, and ascorbate to lyse bacteria.

  • In eutherians, colostral milk is only produced for a short time after birth. During this time, ingested antibodies are protected from intestinal digestive enzymes by antiproteinases present in the colostrum. Intestinal closure to the absorption of antibodies occurs as the composition of mammary secretion changes from colostrum to normal milk, when the levels of antibodies fall rapidly.

  • In marsupials, there is no colostrum as such in the mother's milk. Intestinal closure occurs later in pouch life, so antibodies are present in the milk throughout much of lactation.

General Directions for Eutherians

  • Weigh the animal and select the appropriate weight range from the chart. Mix the appropriate amount of Impact powder with warm pre-boiled water to make the daily Impact requirement. Refrigerate prepared Impact for one day only or store frozen in ice cube trays for up to 1 month.

  • For eutherians, do not mix or feed Impact with milk.

  • For newborns that have NOT received maternal colostrum or milk:

      First 12 hours: Do not feed milk during this time. Prepare a daily dose of Impact as described above and feed of the amount every 2 hours.

      Next 36 hours: Commence feeding milk every 4 hours. Prepare a daily dose of Impact as described above and feed of the amount every 4 hours. Feed Impact 2 hours after the first milk feed so that the remaining Impact feeds are mid way between the next milk feeds.

  • For newborns that have received some milk but no maternal colostrum:

      First 12 hours: Stop feeding milk. Prepare a daily dose of Impact as described above and feed of the amount every 2 hours.

      Next 36 hours: Recommence feeding milk. Prepare a daily dose of Impact as described above and feed of the amount mid way between milk feeds.

See individual animal listings for more information.

General Directions For Marsupials

Marsupials are different in that the mothers do not produce a colostral milk. Impact is added to marsupial milk because intestinal closure occurs later in marsupials and immunoglobulins are present in milk for much of lactation.

  • For very early lactation to mid lactation (Wombaroo <0.4 to 0.6):

      From the chart, select the appropriate amount of Impact powder for body weight. Mix the powder into the required daily volume of milk replacement and feed as usual. This procedure may be repeated for up to 5 days.

  • For late lactation (Wombaroo >0.7):

      From the chart, select the appropriate amount of Impact for body weight and add this to the normal daily feed volume of milk replacement. Repeat if required.
