The Elanco firm presented these investigations which contribute to the advancement of science in the field of animal health and welfare, smart agriculture and sustainable animal husbandry.
During the 31st edition of World Buiatrics Congress (WBC) which took place in September in Madrid, the technical team of Elanco Animal Health presented 7 relevant scientific articles of the company which contribute to the advancement of science in the fields of health and well-being. being animals, livestock health management, smart agriculture and economics, parasitology, nutrition and metabolic diseases and sustainable animal production systems.
Buiatrics is the branch of veterinary medicine specializing in everything related to cattle and ruminants (health, production, reproduction, marketing and industrialization – google.
The main conclusions drawn from this scientific work are as follows:
1- What are the areas of greatest opportunity in the management of dairy cows around calving on farms in Central Eastern Europe?
Authors: Kocik, Marcin; Gunn, Ashley Hayden; Cainzos, Juan; Skupien, Wojciech; Muller, Jakub
- In the 124 farms sampled, there is a large margin for improvement in the management conditions of dairy cows during the transition period, in particular in the groups of dry cows.
- Scarcity of available drinking water in dry and recently calved cows, excessive percentage of cows with high body condition scores in the dry yard, and poor access to feed were the most relevant outcomes.
- Assessing the period around calving in a rigorous and standardized way, makes it possible to advise breeders on the facilities, protocols and management to cover the needs of the cow during the transition.
2- Evaluation of metabolic health through metabolic profiles of samples grouped in 305 Flemish dairy farms
Authors: A. Rijpert, K. De Bleecker; JAG Taelman; J. Van Eecke; H. Deschuytère; J. Schaep; J. Evrard; R. van Saun
The evaluation of the results of the metabolic profile in freshly calved and maximum lactation cows in Flemish dairy farms showed that:
- A considerable number of production groups experience suboptimal conditions with respect to NEB ketosis, dry matter intake, antioxidant and Cu-Zn status, and inflammation.
- The correlation of 5 of the 8 key areas between the 3 production groups presented indicates the need for further evaluation of farm management, feeding, cow comfort, animal welfare and strategies. of prevention.
3- Dynamics of the age of emeriosis in Italian dairy farms
Authors: Marcello Guadagnini, Alessandra Bazzucchi, Marco Gobbi, Nicoletta D’avino
- The data presented in this work show that there is a wide age range for emeriosis
- The detection of pathogenic species is very frequent.
- Larger farms have a high probability of showing a high number of OPGs and for a longer period of time.
- The data confirms the key role of a precise sampling and diagnostic protocol in determining specific Eimeria dynamics and building a control strategy.
4- Prevalence and consequences of diseases in cows at calving in 42 Spanish dairy farms
Authors: Marcello Guadagnini, Noureddine Charfeddine
In this work, the importance of diseases in cows in transition has been demonstrated once again. Firstly, it was possible to identify some risk factors for perinatal pathologies and, furthermore, it was possible to quantify the loss of milk production associated with these pathologies in Spanish farms.
5- Ketosis monitoring in Spain using daily test samples
Authors: Marcello Guadagnini, Gregorio Alcantara, Rita Casals, Fernando Ruíz, Ramiro Fouz, Juan Cainzos
- The prevalence of ketosis and the proportion of high-risk cattle are higher than perceived by much of the dairy industry.
- BHB testing on dairy control samples can provide valuable information about ketosis at the herd and population level.
- High BHB was associated with lower milk production and higher prevalence of subclinical mastitis at first examination.
- Risk factors can help design better prevention strategies.
6- Effect of a Monensin controlled-release capsule on milk production and methane emissions from dairy cows
Authors: Juan Cainzos, Ramiro Fouz, Leane Olivera, Kate Sharon, Marcello Guadagnini
- Monensin CRC increased milk production in the first two milk checks.
- Monensin decreased the estimated methane emission during the first milk recording.
7- Preventive efficacy of toltrazuril (15 mg/kg) against emeriosis in experimentally infected calves
Authors: Welber Daniel Zanetti Lopes, Dina María Beltrán Zapa, Luciana Maffini Heller, Alexandre Braga Scarpa, Alliny Souza De Assis Cavalcante, Rubens Dias De Melo Júnior, Luiz Felipe Monteiro Couto, Gilberto Camargo, Chandra Bhushan, Matheus Marinho
Based on the results of this study, it can be concluded that Baycox 5%, administered orally at a dose of 15 mg/kg, demonstrated persistent efficacy greater than 90.3% for 7 to 14 days and ranging between 54 .8 to 86.2% for 21 to 28 days.
