Welcome to the page about Calf nutrition of Engormix; a source of knowledge on Calf nutrition.
The development and maturation of the calf gut is an important process that significantly influences calf’s growth and health during early life. More and more evidence indicate that the colonization and establishment of the gut microbiome can directly and indirectly influence animal’s gut function including development and metabolism, nutrition absorption, barrier and immune function, endocrine and neuron transmitter secretions, which can impact animals’ development and...

In Spain, the beef fattening system is an intensive system where calves are commonly housed in partially open barns with straw bedding and 40% of the calves, mainly males, are from dairy origin (surplus calves). These calves are transported by road for long hours (up to 3-5 days) from their dairy origin farms to the rearing farm where these calves are fed low amounts of milk replacer for 6-8 weeks and concentrate and straw ad libitum in separate feeders from very young ages with a resulting...

Matheus Paez Martins Narciso (University of Alberta) Although the importance of pH and short-chain fatty acids on rumen development are well known, their impact on the small and large intestine are unclear. This study investigated the effects of ruminal short-chain fatty acid concentrations ([SCFA]) and pH on the rumen and intestine of calves. Holstein bull calves (n = 32) were individually housed and fed milk replacer (900 g/d) twice daily and calf...

Post-calving care for cattle is a critical phase in dairy farming that significantly impacts the health and productivity of both cows and their offspring. Proper care during this period is essential to ensure a smooth transition from pregnancy to lactation and to prevent potential complications. In this article, we will delve into the key aspects of post-calving care for cattle and why it is of utmost importance. Understanding the Significance of Post-Calving Care Calving...

“Don’t drink, don’t smoke, and take your multi-vitamin.” Any pregnant woman can tell you this is the advice they receive from the moment they know they are pregnant. Extensive research in humans and animals has confirmed the long-term impact of nutrition during gestation. Prenatal nutrition can permanently affect both tissues and organs, with life-long consequences to growth and health. Known as epigenetics, it’s the study of changes in gene function...

Introduction At birth, the rumen is non-functional, making calves pre-ruminants. By weaning, the rumen is the principal site of volatile fatty acid (VFA) absorption, responsible for over 50% of all VFA being absorbed (Allen, 1997). Consequently, the calf rumen must undergo a ruminant transition, where the rumen goes from non-functional to functional in 6-10 weeks, coinciding with the period when most dairy calves are weaned (USDA, 2012). The transition...

Introduction Despite many advances in our knowledge of calf management, the dairy industry continues to be challenged with finding ways to raise replacement dairy heifer calves in such a manner that not only optimizes health, growth, and efficiency, but also is best for their welfare. This paper will identify some of those welfare challenges and how we can use knowledge of replacement dairy calf behavior to identify housing and feeding programs that optimize growth, health, and...

INTRODUCTION Raising healthy calves is the foundation for a sustainable and profitable dairy herd. Dam nutrition during the last trimester, calving supervision/assistance, maternity facilities hygiene, umbilical care of calves, colostrum management, and calf nutrition are important factors that impact calf development and health (Lorenz et al., 2011). Calf mortality of 5% or less has been suggested as target for calfrearing operations (Lanuza, 2006). In Chile, however, there is...

The objective of raising beef cattle is to obtaining good quality meat in a short period of time. Prerequisite for that is a healthy herd that turns feed into body mass, under optimal growing conditions where animals feel comfortable. This all starts from the very beginning, under skilled management conditions and with well-balanced nutrition. Selsaf, Actisaf and Safmannan - natural yeast products from Phileo by Lesaffre, have proved to be useful additions to achieving...

THE PHASES OF THE RAISING PROCESS
Under intensive systems, the stage called Calf Rearing lasts approximately up to 60 days (30-60 days) and has three important phases:
1. Pre-ruminant phase - in which the main food is in liquid form, such as milk or a milk replacement. During this phase, the abomasum or true stomach fulfills the main digestive functions.
