The objective of this project is to evaluate how the initial nutrition of neonates affects intestinal bacterial diversity, intestinal and general health, metabolism and performance of dairy calves. For this, three experiments will be carried out, whose focus are: 1) Assess the quality, bacterial diversity, the presence of resistant pathogens and antibiotic residue in colostrum and transit…
The project will be composed of three experiments with the evaluation of different alimentary management and its effects on the ruminal and / or intestinal microbioma, performance and metabolism of dairy calves. In each experiment, 15 calves will be used per treatment in a randomized complete block design. In all experiments the animals will be housed and fed individually, allowing indivi…
The objective of the study was to evaluate different liquid feeding systems with a medium crude protein milk replacer and their effects on performance, rumen and blood parameters. Thirty newborn Holstein calves were blocked according to birth weight and date of birth, and randomly distributed to different liquid feeding systems: i) Conventional: 4L/d; ii) Intensive: 8L/d; iii) Step-up/ste…
Dairy calves performance is associated with management practices and physiological processes related to colostrum feeding. The aim of this project is evaluation of simple methods to ensure good colostrum protocols and the effect of colostrum intake on thermogenesis and metabolism of calves. To determine the best time to estimate calf´s blood immunoglobulin concentration by total protein, …

The solid diet transitions calves from monogastric to polygastric state due to their key role of rumen stimulation, and the goal of solid food is that they consume the amount necessary to meet their nutritional requirements as soon as possible. It is recommended the initial supply of foods in the form of concentrates as their association with the development of ruminal papillae. And studi…
The aim of the study will be to evaluate the performance, metabolism and health of Holstein calves fed whole milk corrected or not to 15% total solids using a commercial product. Forty- five Holstein calves will be used in a randomized block design, considering birth weight and birth date as blocking effect. The calves will be housed in individual suspended cages until 14 days of age, and…
Due to its effects on the rumen development process, fiber supply is usually low in diets for dairy calves. Thus, these animals' fiber requirement is not well known, with significant variation in the recommendations. On the other hand, the supply of diets with high starch content and reduced particle size can result in a high rate of fermentation and acid production in the rumen, benefiti…
Raising calves is widely recognized as one of the pillars of future milk production, and the provision of high-quality colostrum in the first hours of a newborn's life is an extremely important and decisive factor in the development of healthy females. Like colostrum, transitional milk also has bioactive compounds with the potential to assist the development and intestinal health of the a…
Determination of serum glucose status of preweaned calves is important for understanding the changes in the metabolism from a pre-ruminant to a functional ruminant. The present work aims to evaluate the peak of serum glucose concentration according to the liquid diet fed to dairy calves (milk or milk replacer). Therefore, we seek to standardize the time for blood sampling in order to char…
The objective of the study is to evaluate the supplementation of whole corn grain with the starter concentrate as a source of fiber on the performance, metabolism and ruminal development of Holstein dairy calves. Thirty - six Holstein calves will be used in a randomized complete block design, considering the weight of the calves at 28 d, when the supplementation is started. The animals wi…

This study aims to evaluate different levels of the replacement of corn silage by triticale silage using an artificial rumen (Rusitec). The experiment will run as a completely randomized design with a factorial treatment structure (proportion triticale silage: corn silage; 0:100, 33:67, 67:33, and 100:0) replicated in two Rusitec apparatuses (n = 8 fermenters). Fermenter will be considere…
The experiment will be a 2 x 2 x 2 factorial arrangement of 8 treatments with 8 anaerobic dual-flow continuous cultures and 4 periods in a randomized incomplete block. The continuous cultures will be randomly assigned to a treatment with either BCVFA supplementation (2 mmol/d of isobutyrate, 2 mmol/d isovalerate, and 2 mmol/d 2-methylbutyrate) or no additional BCVFA, high forage: concentr…
The objective of this research proposal is to evaluate performance, blood metabolites and production costs of calves fed milk replacer or whole milk and traditional or a modified calf starter program in low environmental temperature. The study will utilize 75 Holstein heifer calves. All calves will be receive 4 L of colostrum within 4 to 6 hours of birth. Birth weights will be recorded an…
