NEWS 82 FEED & ADDITIVE MAGAZINE December 2022 The Food and Agriculture Organization of the United Nations (FAO), the UN Environment Programme (UNEP), the World Health Organization (WHO) and the World Organisation for Animal Health (WOAH) are joining forces on Antimicrobial Resistance Multi-Stakeholder Partnership Platform to underscore the threat antimicrobial resistance (AMR) presents to humans, animals, plants, ecosystems and livelihoods. An estimated 1.3 million people around the world die each year directly due to bacterial antimicrobial resistance (AMR). If no action is taken, that number could soar dramatically, bringing higher public health costs and pushing more people into poverty, especially in low-income countries, underscoring the need for the Platform to mobilise further coordinated efforts. Antibiotics and other antimicrobials play a key role in the success of modern medicine and have greatly improved the health of humans and animals. But overuse and misuse have reduced their efficacy, with more pathogens developing the ability to survive the antimicrobials designed to eliminate them.

Results from international research groups show positive effects on the growth and development in early life of calves when nutrient intake before weaning is increased. According to the research of Schothorst Feed Research (SFR), intensive calf milk (replacer) programs have positive results on the growth of calves. However, there is large variation in growth between individual animals. Factors in early life may have an effect on production performance in later life. Several studies have shown that maintaining a growth of more than 500 grams per day in the period before weaning has a positive effect on production in the 1st lactation. SFR explains the research details as follows; The effect of birth weight and growth before weaning on milk production results in 1st, 2nd and 3rd lactation has been investigated. A dataset has been created with data from heifer calves born from 2016 to 2019. This includes the information about the calf, including birth weight and the growth from birth to weaning. Subsequently, production data of these animals as dairy cows were extracted from the management system. This resulted in a dataset including information of 161 dairy cows. For analysis, the data was divided into groups of calves with a low, medium, and high birth weight and also in low, medium and high growth before weaning.
