Investigación muestra que animales de primera lactancia se benefician de haber sido alimentados con leche entera en la crianza

Extract: 

En un estudio publicado recientemente se mostró que novillas alimentadas con leche entera antes del destete produjeron más leche durante la primera lactancia que las alimentadas con sustituto de leche. Los investigadores israelíes publicaron estos resultados en la edición de junio del Journal of Dairy Science.

UV Light Inactivation of Mycobacterium avium subsp. paratuberculosis in Milk as Assessed by FASTPlaqueTB Phage Assay and Culture

Extract: 

UV light has been used for the disinfection of drinking water and wastewater systems to inactivate potential waterborne pathogens for many years (2). UV light at wavelengths shorter than 280 nm (termed UV-C) has a germicidal effect on most types of microorganisms by formation of thymine dimers in DNA and RNA that inhibit transcription and replication of nucleic acids, thereby rendering the microorganism unable to reproduce (12, 17).

Inactivation of Mycobacterium avium ssp. paratuberculosis in milk by UV treatment

Extract: 

Mycobacterium avium ssp. paratuberculosis (Map) is the known cause of Johne’s disease which affects both wild and domestic ruminants (Beard et al. 2001), particularly dairy cattle (Clarke 1997). The organism has also been implicated as a cause of Crohn’s disease in humans that manifests as a chronic enteritis which is incurable, although sufferers can experience periods of remission (Behr and Kapur 2008). Myco. avium ssp. paratuberculosis is excreted directly into the milk and faeces of infected animals in low and very high numbers respectively (Cocito et al. 1994).

Research shows first-lactation benefit to feeding whole milk to calves

Extract: 

In a recently published study, heifers fed whole milk before weaning produced more milk during their first lactation than those fed milk replacer as calves. Israeli researchers published these results in the June issue of the Journal of Dairy Science.

 

Effects of Feeding Heat-Treated Colostrum on Passive Transfer of Immune and Nutritional Parameters in Neonatal Dairy Calves

Extract: 

“The most exciting result from this study was that feeding heat-treated colostrum resulted in greater serum IgG concentrations in calves, despite the fact that calves in both treatment groups were fed the same total mass of IgG at the same time after birth and using the same feeding method. The authors hypothesize that greater serum IgG concentrations could have resulted because calves receiving heat-treated colostrum were able to absorb a greater proportion of the total mass of IgG presented to the small intestine.”

Heat-Treatment of Bovine Colostrum. II: Effects of Heating Duration on Pathogen Viability and Immunoglobulin G

Extract: 

“Large (30-L) batches of moderate- to high-quality bovine colostrum can be heat-treated in a commercial on farm batch pasteurizer at 60°C for at least 120 min without affecting the IgG concentration or sctivity. Mycoplasma bovis, L. monocytogenes, E. coli O157:H7, and S. enteritidis added tocolostrum could not be recovered after colostrum was heat-treated at 60°C for 30 min. Heat-treatment at 60°C for 60 min should be sufficient to eliminate Mycobacterium avium subsp. paratuberculosis (Map) from colostrum in most situations.”

Calf Diseases and Prevention

Extract: 

“The productivity of the herd can be negatively impacted by impaired growth of calves, decreased milk production of animals that experienced chronic illness as baby calves, spread of infectious diseases from calves to adult cows, increased veterinary costs and the limited opportunity for genetic selection due to high mortality of replacement animals."

On-Farm Batch Pasteurization Destroys Mycobacterium paratuberculosis in Waste Milk

Extract: 

“These results suggest that batch pasteurization of waste milk contaminated with M. paratuberculosis was effective at generating a clean product to feed to young calves.”

Pasteurized Milk and Colostrum for Calves: An Option or Necessity?

Extract: 

 

“Studies have shown that pasteurization, both batch and HTST, is effective in destroying viable bacteria for most of the pathogenic species threatening calves. Two studies to-date have used commercial on-farm pasteurization units; one a batch unit, the other HTST–both demonstrated that the pasteurization unit effectively destroyed the Johne’s organism.”
