Anaerobically fermented colostrum: an alternative for feeding calves

Abstract

Milk or commercial milk replacer blends are the most expensive components in fi nal costs of calves breeding. Colostrum is available and it is the appropriate sources for calves' nutrition

Dairy goat kids fed liquid diets in substitution of goat milk and slaughtered at different ages: an economic viability analysis using Monte Carlo techniques

“…According to 4.5 ± 0.1 4.7 ± 0.1 3.7 ± 0.1 4.6 ± 0.1 3.2 ± 0.1 2.1 ± 0.1 DM = dry matter; EE = ether extract; NFC = non-fiber carbohydrates; ME = metabolizable energy. Saalfeld et al (2013), fermented colostrum should be classified as having a cost of zero because excess of colostrum does not have any market destination and is normally disposed of in nature. Although in Brazil, as in many other countries, there is no established price for this product, we decided to compute the costs of milking in the 3 days postpartum so that dairy cow farmers could be paid for this work.…”

“…This was most likely due to the high acidity level of fermented colostrum (Saalfeld et al, 2013), which demands more care and, as a consequence, higher labor costs. On the basis of the veterinarian's examination, all kids were healthy until slaughtering, except for some animals fed fermented colostrum, which had diarrhoea from the 5 th to 10 th day, probably due the change of the diet during the adaptation phase.…”

Effect of anaerobic bovine colostrum fermentation on bacteria growth inhibition

“…The inoculums criteria were based in the highest count found in contaminated milk samples by the diagnostic laboratory of School of Veterinary at the Universidade Federal de Pelotas. After bacterial inoculations, each of the eight aliquots was fractionated into five polyethylene terephthalate (PET) 226mL bottles, which were completely filled, closed and stored for anaerobic fermentation of the colostrum as previously described by SAALFELD et al (2013). In addition, five aliquots were stored without bacterial inoculation, constituting the negative control of the experiment.…”

“…Storing surplus colostrum by freezing (RAMÍREZ-SANTANA et al, 2012), aerobic acidification (FOLEY & OTTERBY, 1978), use of organic additives (GARCIA et al, 1981), or by anaerobic fermentation (SAALFELD et al, 2013) allows surplus colostrum to be employed in feeding more animals. Anaerobic fermentation (colostrum silage) preserves the nutritional constituents, and ensures the transfer of antibodies to calves (SAALFELD et al, 2013(SAALFELD et al, , 2014. Our group demonstrated that environmental microbial contamination of natural colostrum can be eliminated with 21 days of anaerobic fermentation, remaining only lactic acid bacteria (LAB) as viable (SAALFELD et al, 2013).…”
