“…An experiment conducted on calves from d 3 to d 56 concluded that weight gain and health parameters were not influenced by feeding on untreated waste milk, pasteurized waste milk, or bulk milk [1]. Similar results have also been reported in the literature [7, 25–27], which did not observe detrimental effects of waste milk on growth performance and calf health.…”

BackgroundThe present experiment was performed to assess the effects of different sources of milk on the growth performance, serum metabolism, immunity, and intestinal development of calves. Eighty-four Holstein male neonatal calves were assigned to one of the following four treatment groups: those that received bunk tank milk (BTM), untreated waste milk (UWM), pasteurized waste milk (PWM), and acidified waste milk (AWM) for 21 d.ResultsCalves in the BTM and AWM groups consumed more starter (P < 0.05) than those in the UWM group. Average daily gain in the UWM group was the highest (P < 0.05). Calves exhibited the highest (P < 0.05) serum total protein, albumin, total cholesterol, high density lipoprotein, triglycerides, growth hormone, immunoglobulin (Ig) A and IgM concentrations in the UWM group, highest malondialdehyde and tumor necrosis factor-α in the PWM group (P < 0.05), and highest glutathione peroxidase and IgG in the BTM group (P < 0.05). The jejunum and ileum of the calves in all treatments presented a slight inflammatory response. The jejunal inflammation scores were higher (P < 0.05) in the UWM and AWM groups than the BTM group; the ileal inflammation scores increased more (P < 0.05) in the AWM group than the BTM group. Jejunal immunohistochemical scores (IHS) were higher (P < 0.05) in the PWM and AWM groups than the BTM group. Compared to the other three groups, calves feeding on BTM had lower (P < 0.05) ileal IHS. Jejunal interleukin(IL)-1β, IL-8, and IL-10 mRNA expression in the UWM group was the highest (P < 0.05). Calves fed AWM increased (P < 0.05) mRNA expression of IL-8 and toll like receptor 4 (TLR-4) in the jejunum and IL-8, IL-1β, IL-6, IL-8, and IL-10 in the mesenteric lymph nodes.ConclusionsOverall, bunk tank milk is the best choice for calf raising compared to waste milk. The efficiency of feeding pasteurized and acidified waste milk are comparable, and the acidification of waste milk is an acceptable labor-saving and diarrhea-preventing feed for young calves.

“…These practices have also been reported to be common in other countries (Brunton et al, 2012;Duse et al, 2013), in an attempt to reduce calf-rearing costs by using milk that would otherwise be discarded. Early evidence reported that these practices resulted in no differences in growth or morbidity compared with control milk (Kesler, 1981). However, they have been associated with higher levels of antimicrobial-resistant bacteria in the gastrointestinal tracts of calves (Aust et al, 2013;Duse et al, 2015).…”

Calf preweaning morbidity and mortality risks have been reported as high in several countries, with average values approximating 35 and 7%, respectively. However, limited data are available for calf morbidity and mortality risks on Australian dairy farms. The aims of this study were (1) to investigate current calf management practices on dairy farms in Australia and their association with herd-level morbidity and mortality using a questionnaire-based, cross-sectional study; and (2) to estimate the prevalence of common enteropathogens causing diarrhea, the failure of passive transfer of immunity, and poor colostrum quality in a sample of Australian dairy farms. We analyzed 106 completed questionnaires and samples from 23 farms (202 fecal, 253 calf serum, and 221 colostrum samples). Morbidity and mortality risks reported by farmers in preweaned heifers were 23.8 and 5.6%, respectively. These risks were above the Australian dairy industry targets in 75.5 and 66.7% of respondents. The zoonotic pathogens Cryptosporidium spp. and Salmonella spp. were the most prevalent enteropathogens, with a true prevalence of 40.9 and 25.2%, respectively. Salmonella O-group D was present in 67.9% of Salmonella-positive samples, followed by O-groups B (17.9%) and C (10.7%). Failure of transfer of passive immunity (IgG <10 g/L) was observed in 41.9% of calves (mean herd-level prevalence of 36.2%), and only 19.5% of colostrum samples met the standards for immunoglobulin content and microbiological quality. Collectively, these data indicate that there is still considerable room for improvement in calf-rearing practices on Australian dairy farms, particularly with regard to colostrum management and feeding hygiene.

“…Farms where calves were fed waste milk (that is, from treated or mastitic cows) or milk replacer had significantly increased odds of having abovemedian summer morbidity (Table IV). A recent review of feeding waste milk to calves concluded that, with a few exceptions, no increased risk of disease in calves was associated with this practice (Kesler, 1981). The health effects of feeding milk replacer have been reported to be related to the quality of the replacer used, and the methods of preparation (Roy, 1980a).…”

Med., Associations between heifer calf management and morbidity, particularly scours and pneumonia, were studied on 104 randomly selected Holstein dairy farms in southwestern Ontario between October 1980 and July 1983. At the farm level, data were stratified by season, with two six-month seasons (winter and summer) per year. The odds of farms with particular management strategies having above median morbidity were calculated. At the individual calf level, the odds of a calf being treated, controlling for farm of origin and month of birth, were calculated for different management practices.Farm size, and policies related to anti-scour vaccination, offering free-choice water and minerals to calves, methods of feeding, and the use of medicated feeds significantly altered the odds of a farm experiencing above-median pneumonia rates. Farm policies with regard to anti-scour vaccination, offering free-choice salt to calves, age at teat removal, type of calf housing, and use of preventive antimicrobials significantly altered the odds of a farm experiencing above-median scours rates.Scours and pneumonia were significantly associated with each other at both the farm and the calf level. No significant associations were found between individual calf management practices and the odds of being treated for scours. Sire used, method of first colostrum feeding, navel treatment, use of anti-scour vaccine in the dam, and the administration of preventive antimicrobials significantly altered the odds of a calf being treated for pneumonia.
