Outcome Parameter(s): Udder health status
Summary: It is crucial to define a consistent and approved procedure to identify cows that need to be treated in a selective dry cow therapy approach. Somatic cell counts (SCC) from milk test records are a convenient, accurate and certified method. SCC values obtained before drying off or calculated as the average of lactation records can be used. The thresholds of 100,000 cells for primiparous cows and of 200,000 cells for pluriparous cows are suggested as an efficient and sustainable decision tool.

Significant Impact Group(s): Breeding for disease resistance or robustness ; Pathogen management
Species targeted: Dairy;
Age: Adult;
Outcome Parameter(s): Immune response in dairy cattle
Summary: Dairy cows face very high metabolic demands have increased difficulties adapting to the environment. This leads to increased replacement rates and frequent occurrence of diseases and drug use. This article reviews how a good understanding of the immune system is crucial in managing mastitis in dairy cows.

36 What we have lost: Mastitis resistance in Holstein Friesians and in a local cattle breed (Research paper; Curone, 2018)

Significant Impact Group(s): Breeding for disease resistance or robustness
Species targeted: Dairy;
Age: Adult;
Outcome Parameter(s): Bacteriogical status; Mammary immune response; colostrum protein profile
Summary: A multidisciplinary approach was applied to compare innate immune response patterns, metabolic parameters, milk protein profiles and the milk microbiota in Holstein Friesian and Rendena cows reared in the same farm and under the same management conditions. Results show that Holstein Friesian and Rendena cows have different metabolic traits. Mastitis markers are higher in Holstein Friesian milk. The microbiota biodiversity is lower in Rendena milk. The colostrum protein profile is markedly different in the two breeds. Mammary innate immune response patterns display breed-specific differences. The observations reported in this work present numerous pointers to the factors that may provide more rustic breeds with a higher resistance to disease.

26 Potential dietary feed additives with antibacterial effects and their impact on performance of weaned piglets: A meta-analysis (Research paper, Vanrolleghem et al., 2019)

Significant Impact Group(s): Feed / gut health \ Feed additives and supplements – Feed additives and supplements ; Specific alternatives

Species targeted: Pigs;
Age: Young;
Outcome Parameter(s): growth parameters; ‘average daily gain’ (ADG); ‘feed conversion ratio’ (FCR)
Summary: Between January 2010 and January 2017, 23 in vivo studies (comprising 50 trials) were published that evaluated the use of potential dietary feed additives (pDFA) against a positive control diet with antibiotics in weaned piglets, and reporting the performance parameters average daily gain’ (ADG) and ‘feed conversion ratio’ (FCR). The results of the meta-analysis clearly show that adding a pDFA at weaning can improve performance indicators compared to an untreated group (negative control), suggesting that pDFA could increase growth and improve feed conversion. As such, pDFA could potentially enhance production without the negative side effect of AMUs. Compared to the use of AMUs (positive control), the results of the meta-analysis show no overall significant difference. This is a beneficial result, as it suggests that the use of AMUs around weaning, a very commonly used practice, could be replaced by pDFA without significant negative effects on the performance indicators.

Significant Impact Group(s): Biosecurity \ Internal biosecurity \ Housing

Species targeted: Poultry;
Summary: Research was carried out to set up a new machine for floor disinfection of poultry houses by open flame. The trials were run in controlled conditions in the laboratory of the University of Pisa, Italy, and on a private farm. The results obtained were very promising. Test bench trials showed a substancial reduction in E. coli, and microbial determinations carried out on-farm did not show any difference between thermal and chemical treatment. In addition, the cost estimation showed that thermal disinfection is approximately 4-fold cheaper than chemical sanitation methods. The effective working capacity of the machine was approximately 1700 m2 h–1, and the LPG consumption was approximately 16 kg per 1000 m2. Flame disinfection of poultry grow-out facilities could represent a valid alternative to chemical disinfection.
