There is a scientific gap about the use of hormonal protocols for inducing puberty in Nellore heifers exposed to reproduction from 12-14 months of age. The main objective of the study is to demonstrate that inducing puberty with progesterone may not be enough for heifers to actually enter puberty (continuation of estrous cycles) and that many ovulate only by hormonal induction and return …
This project aims to strengthen research ties between the States of Amazonas and São Paulo in the beef cattle production. Thus, the objectives of this project are: 1) To assess whether yearling Nellore heifers that were induced to puberty by hormonal protocol have the same reproductive performance compared to heifers that reached puberty spontaneously. 2) Assess whether trace minerals (Cu…
Food additives used in ruminant nutrition are tools that can improve the conversion of forage to animal protein and increase nutrient utilization efficiency. There is an important gap to be filled by research involving the use of molecules capable of altering the fermentation process in ruminants fed diets containing high forage content. Narasin is a molecule released in the market in 201…
The objectives of this project are: 1) To evaluate the effect of doses of Sodium Monensin and Narasin in diets of cattle. Experiment I: Eight steers, Nelore, cannulated in the rumen, will be used in a double 4 X 4 Latin Square design. The animals will be fed with Coastcross hay and the treatment will be: Control (without ionophore), M7.5 (7.5 ppm of Monensin), M15 e M22.5. Will be evalua…

The food production in the world needs to increase around 70% by 2050 to feed an additional 2.3 million people. The expected increase in beef consumption is even greater, and its production is expected to increase from 60 to 130 million tonnes in the same period (FAO, 2013) using the same resources in limited areas. Therefore, only increasing the efficiency in the segment can provide stra…
The project aims at assessing the effects of the ionophore narasin inclusion through protein and mineral supplement on the performance of grazing beef cattle steers, over five periods of 28 days. 150 steers will be used in a complete block design. Each experimental unit will be composed of 5 animals. The treatments will be: T1 - Mineral control (absence of narasin), T2 - Mineral + narasi…
The objective of experiment is to evaluate the interaction among metabolic imprinting from 3 to 7 month of age, expected progeny differences (EPD; genetic factor) and age on puberty of Crossbreed (Angus x Nellore) heifers. Will be used 66 crossbreed heifers Angus x Nellore (Bos Taurus taurus x Bos taurus indicus) weaned at three months old, coming from fixed time artificial insemination (…

Thirty transition Jersey cows will be used for this project. Cows will be blocked based on parity and date of calving; cows within a block will be randomly assigned to one of the two diets: 1) control and 2) a single oral dose of 200 mL of Megasphaera elsdenii (Lactipro; MSBiotec, Littleton, CO; product is already available commercially; 10^8/mL of organism) will be drenched within 24 hr …
Age at puberty directly influences the performance of the animal in future years. There has been considerable research on nutritional influences on puberty in heifers, but a majority of this has focused on the period after traditional weaning (after 7 months of age). Onset of puberty is gated by an activation of the neuroendocrine system that leads the onset of ovarian activity. Several r…
