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.

Introduction The dominant primary plant formation in the Cacaueira is a dense ombrophilous forest, known like Atlantic rainforest or simply Atlantic forest. This biome is found along of the Brazilian coast, covering the coastal plains and eastern slopes of the Serra do Mar and Serra General, at altitudes of up to 600-700 m. The Forest Atlantic had as its basic characteristic, luxuriant vegetation, high and developed, whose structure and composition varied by region; presented...

For the last few months, it seems that immunity has been at the forefront of our thought process – not just for the dairy industry but world-wide. While everyone has been focused on staying healthy and have become increasingly aware of the importance of a well-functioning immune system (IS), these are concepts that the dairy producer needs to keep in mind almost every day.
The IS in all animals is critical and complex. Life is dependent on a functional IS. Its primary function...

Introduction An area of nutrition that is commonly overlooked in foot health managment is the role trace minerals play in improving claw health, structural integrity and reducing incidence of lameness. Trace minerals are important to production and maintenance of healthy keratinized tissues (Mulling et al., 1999). Increasing the bioavailability of trace minerals improves their utilization and thus may help improve claw horn...

Previous studies showed that inclusion of polyphenol-rich plant extracts in feed improves performance in ruminants, but the effect may vary depending on the dosage used. It has been shown that polyphenols modify the digestive process through modulation of gastrointestinal microbiota and bypass of protein digestion. The rumen houses a highly complex microbiota which is able to convert indigestible plant mass into energy mainly through production of short-chain fatty acids...

Increasing effect on energy efficiency and fertility In dairy farming, especially with high-producing grass-fed cows, the optimisation of rumen fermentation parameters poses an important challenge. In this context, obtaining an adequate dietary energy: protein ratio is a key nutritional goal, not only for the level of performance but also for the fertility of dairy cows. When referring to the relationship between...

Introduction There are numerous reasons behind the diffusion of cacti as forage or fodder around the world, such as the simple cultivation practices required to grow the crop, rapid establishment in a new area, easy multiplication practices (18). Also, they have the ability to withstand prolonged drought, high temperatures as well as soils affected by wind and water erosion (16). This aptitude has made the cactus plantations suitable as food supply and they have become strategic...

As of January 2017, the FDA began a stricter regulation of antibiotics commonly used in the animal-feeding industry. Livestock and poultry producers alike have been accused of overfeeding various antibiotics, largely for growth promotion purposes (i.e., for increased feed efficiency and profitability).
The ones the medical industry and the consumer have been most concerned with are those deemed medically important for human use. The perception is: Various infectious agents that...

Many dairy cows in the developed world are now housed exclusively indoors with fewer than 5% of the 10 million lactating cows in the United States having access to pasture during the grazing season. Indoor housing systems are designed to meet biological needs for food, water, hygiene, and shelter, but surveys of public and farmer opinion suggest that people think that pasture access is also important for the well-being of dairy cows. To determine if pasture...

Introduction
Past research in dairy cattle nutritional management has focused almost exclusively on the nutritive aspects of the diet, resulting in many discoveries and improvements in dairy cow health and production. Despite many advances this field we are still faced with several challenges associated with feeding dairy cattle. Recent field observations suggest that housing and management can play as large of a role as nutrition in the performance and health of...
