The relationship between transition period diseases and lameness,feeding time, and body condition during the dry period by Daros, R.R., Eriksson, H.K., Weary, D.M. and M.A.G. von Keyserlingk 2020 Journal of Dairy Science 103: 649-665
In Significant Impact Groups: Precision Livestock Farming & Early detection \ Sensor technology
Species targeted: Dairy;
Age: Adult;
Summary:
This research did record feeding time by placing cameras by the feed bunk and using different digital systems. Lameness was scored as well as body conditions score. The results support the hypothesis that lameness during the dry period is associated with transition diseases. Lameness identified 2 mo before calving was associated with increased risk of transition diseases, highlighting the importance of screening cows for lameness around dry-off. One of the mechanisms through which lameness may be associated with TD is through decreased feeding time; throughout the dry period, lame cows spent less time feeding than sound cows, and lower feeding time was in turn associated with higher odds of transition diseases. These results suggest that reducing lameness during the dry period and avoiding over conditioning at dry-off may improve transition health.

Passive immunisation, an old idea revisited: Basic principles and application to modern animal production systems by Hedegaard C.J. and P.M.H. Heegaard
2016 Veterinary Immunology and Immunopathology Volume 174: 50-63
In Significant Impact Groups: Prudent use AB \ Veterinarian
Species targeted: Pigs; Poultry; Dairy; Beef; Sheep;
Age: Adult;
Summary:
Immunisation by administration of antibodies (immunoglobulins) has been known for more than one hundred years as a very efficient means of obtaining immediate, short-lived protection against infection and/or against the disease-causing effects of toxins from microbial pathogens and from other sources. This review highlights a number of examples on the use of passive immunisation for the control of infectious disease in the modern production of a range of animals, including pigs, cattle, sheep, goat, poultry and fish. It is concluded that provided highly efficient, relatively low-price immunoglobulin products are available, passive immunisation has a clear role in the modern animal production sector as a means of controlling infectious diseases, importantly with a very low risk of causing development of bacterial resistance, thus constituting a real and widely applicable alternative to antibiotics.

Finding alternatives to antibiotics by Allen, H.K., Trachsel, J., Looft, T. and T.A. Casey 2014 Annals of the New York Academy of Sciences 1323: 91-100
In Significant Impact Groups: Prudent use AB \ Veterinarian
Species targeted: Pigs; Poultry; Dairy; Beef; Sheep;
Age: Adult;
Summary:
The spread of antibiotic-resistant pathogens requires new treatments. As the rate of development of new antibiotics has severely declined, alternatives to antibiotics must be considered in both animal agriculture and human medicine. Products for disease prevention are different from those for disease treatment, and examples of both are discussed here. For example, modulating the gut microbial community, either through feed additives or fecal transplantation, could be a promising way to prevent certain diseases; for disease treatment, non-antibiotic approaches include phage therapy, phage lysins, bacteriocins, and predatory bacteria. Interestingly, several of these methods augment antibiotic efficacy by improving bacterial killing and decreasing antibiotic resistance selection. Because bacteria can ultimately evolve resistance to almost any therapeutic agent, it is important to continue to use both antibiotics and their alternatives judiciously.

Age: Not stated;
Summary:
The widespread use of antibiotics in animals is causing concerns about the growing risk for development and the spread of antibiotic-resistant bacteria. Antibiotic consumption is higher in animals than in humans as reported in a joint publication of EFSA (European Food Safety Agency), ECDC (European Centre for Disease Prevention and Control), and EMA (European Medicines Agency) using data from 2011 and 2012. Both in humans and animals, positive associations between the consumption of antibiotics and resistant bacteria are observed. Responsible use of antibiotics in humans and animals should therefore be promoted. In this paper some general aspects of antibiotic resistance such as microbiological versus clinical resistance, intrinsic versus acquired resistance, resistance mechanisms, and transfer of resistance are briefly introduced.

Milk acidification to control the growth of Mycoplasma bovis and Salmonella Dublin in contaminated milk by Parker, A.M., House, J.K., Hazelton, M.S., Bosward, K.L., Mohler, V.L., Maunsell and P.A. Sheehy 2016 Journal of Dairy Science 99: 9875–9884
In Significant Impact Groups: Feed / gut health \ Early feeding (colostrum/feed)
Species targeted: Dairy;
Age: Young;
Summary:
Bacterial contamination of milk fed to calves compromises calf health. Several bacterial pathogens that infect cows, including Mycoplasma bovis and Salmonella enterica ssp. enterica serovar Dublin, are shed in milk, providing a possible route of transmission to calves. Milk acidification lowers the milk pH so that it is unsuitable for bacterial growth and survival. The objectives of this study were to (1) determine the growth of M. bovis and Salmonella Dublin in milk, and (2) evaluate the efficacy of milk acidification using commercially available acidification agent (Salstop, Impextraco, Heist-op-den-Berg, Belgium) to control M. bovis and Salmonella Dublin survival in milk. Results demonstrate that milk acidification using Salstop is effective at eliminating viable M. bovis and Salmonella Dublin organisms in milk if the appropriate pH and exposure time are maintained.

Species targeted: Dairy;
Age: Young;
Summary:
The 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.Conclusions: Overall, bunk tank milk is the best choice for calf raising compared to waste milk. The efficiency offeeding pasteurized and acidified waste milk are comparable, and the acidification of waste milk is an acceptablelabor-saving and diarrhea-preventing feed for young calves.

Effects of butyric acid supplementation of acidified milk on digestive function and weaning stress of cattle calves by Sun, Y.Y., Li, J., Meng, Q.S., Wu, D.L. and M. Xu
2019 Livestock Science Volume 225: 78-84
In Significant Impact Groups: Feed / gut health \ Early feeding (colostrum/feed)
Species targeted: Dairy;
Age: Young;
Summary:
Feed supplements can enhance the health and productivity of livestock. The effects of butyric acid supplementation of acidified milk (AM) on the digestive function of calves and weaning stress were investigated. Thirty-six Holstein calves with a mean age of 5 ± 1 d were selected and divided into three groups (n = 12) and fed: (1) AM (CON); (2) AM + 0.3% butyric acid (BA0.3); or (3) AM + 0.6% butyric acid (BA0.6). Body weight (BW) and body size indicators were recorded during the preweaning stage. At 56 d, 18 calves were euthanized to determine the length and width of their ruminal papillae, duodenum villi, jejunum villi, and ileal villi; emptied rumen, reticulum, omasum, and abomasum weight; and small intestinal mucosa thickness. In conclusion, the addition of butyric acid to AM can reduce the rate of diarrhea, weaning stress and improve metabolic and physical development of the gastrointestinal tract.
