Item Uso parenteral de cromo orgânico em bezerras da raça holandesa(Universidade Brasil, 2022) Silva, Cairon Rony Bezerra da; Melo, Gabriel Maurício Peruca de; Melo, Wanderley José deThis study aimed to evaluate the effects of different doses of parenteral organic chromium in 24 Holstein heifers. The experiment was carried out in a completely randomized design, with 3 treatments (T1. Control - without parenteral chromium supplementation; T2. Parenteral supplementation of organic chromium - 100 mg/animal every 28 days; T3. Parenteral supplementation of chromium in the organic form - 200 mg per animal applied at intervals of 28 days) and 8 repetitions. The experiment lasted 56 days, with weighing of the experimental animals every 28 days. The parameters of daily weight gain and total weight gain were evaluated. Chromium supplementation promoted an improvement in the weight performance of the heifers, with an average daily weight gain of approximately 30% higher than in the control group, regardless of the evaluated dose. It was concluded that organic chromium, independent of a supplementary way, for heifers of the breed allows additional weight gain.Item Desempenho de novilhos Nelore suplementados com cromo orgânico injetável(Universidade Brasil, 2021) Carli, Carlos Henrique Andrade de; Melo, Gabriel Maurício Peruca de; Melo, Wanderley José deMinerals play a fundamental role in several reactions in animal metabolism, acting in the most different organic systems with a diversity of functions and directly influencing bovine performance. In this sense, the use of organic minerals in ruminant feed has provided positive responses in production, as is the case of organic chromium (Cr). The objective of the study was to evaluate the physiological performance of Nelore yearling steers when supplemented with injectable organic chromium, as a viable source for nutrition and development of yearling steers intended for beef production. The experiment was conducted in an entirely randomized design, with three treatments (T1 - control, no organic chrome supplementation; T2 - organic chrome supplementation, 5 mL/animal applied at 14 day intervals and T3 - organic chrome supplementation, 5 mL/animal applied at 28 day intervals), 10 repetitions over a 56 day experimental period. Organic chromium supplementation improved the weight performance of yearling steers (21.90% higher). This better performance can be explained by changes in the metabolic profile of supplemented animals, and it can be concluded that organic chromium supplementation in Nelore male cattle recently weaned allows additional weight gain without compromising the metabolic profile of glucose in these animals.Item Galactopoese em vacas suplementadas por via parenteral com aminoácidos e vitaminas(Universidade Brasil, 2016) Casale, Roberta Vanessa Pinho; Belo, Marco Antonio de AndradeItem Desempenho e glicose plasmática de bezerras lactentes suplementadas com doses de Cromo Orgânico injetável(Universidade Brasil, 2016) Martins, Jackson Antônio Ribeiro; Melo, Gabriel Maurício Peruca de
