de Oliveira Bezerra, Alexandre; Nicacio, Alessandra Corallo; de Oliveira Menezes, Gilberto Romeiro; da Costa Gomes, RodrigoMade available in DSpace on 2019-10-06T17:13:23Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-09-01; Empresa Brasileira de Pesquisa Agropecuária; Due to the increasing use of in vitro embryo production (IVEP) and the importance of crossbreeding for beef production, pregnancy rates of Nelore recipients were evaluated following Fixed Time Embryo Transfer with fresh or vitrified IVEP embryos produced with...
Supplementation of cows with linseed: effects on antral follicle count, oocyte ...
Cardoso, Christopher Junior Tavares; Lima, Ana Caroline Bini de; Silva, Wilian Aparecido Leite da; Souza-Cáceres, Mirela BrochadoLinseed is distinguished by its composition of fatty acids, which are rich in unsaturated acids, and by the slow release of oil in the rumen, consequently providing a greater amount of lipids of interest for intestinal absorption. The aim of this study was to evaluate the effect of linseed supplementation on the antral follicle count (AFC) and oocyte quality of Girolando cows, as well as their digestive paramet...
Membrane lipid profile of in vitro-produced embryos is affected by vitrificatio...
Leão, Beatriz C. S. [UNESP]; Rocha-Frigoni, Nathália A. S. [UNESP]; Nogueira, Ériklis; Cabral, Elaine C.; Ferreira, Christina R.; Eberlin, Marcos N.Made available in DSpace on 2018-12-11T16:47:21Z (GMT). No. of bitstreams: 0 Previous issue date: 2017-01-01; Dietary rumen-protected polyunsaturated fatty acids (PUFAs) rich in linoleic acid (LA) may affect embryo yield, and LA can modulate the molecular mechanisms of lipid uptake in bovine blastocysts produced in vitro. In embryos, membrane lipids, such as phosphatidylcholines (PCs) and sphingomyelins (SMs), ...
Performance and digestive characteristics in dairy cattle maintained under graz...
Cardoso, Christopher Junior Tavares; Lima, Ana Caroline Bini de; Nogueira, Ériklis; Oliveira, Marcus Vinicius Morais de; Melo-Sterza, Fabiana de AndradeLinseed is characterized by the rich unsaturated fatty acids and slow release of oil in the rumen. The objective of the present study was to evaluate the intake, rumen degradability, and digestibility of dairy cattle maintained under grazing regime and supplemented with linseed. Twelve Girolando (¾ Holstein × ¼ Gir) cows with a mean age of 5.2 ± 1.9 years and body weight of 583.9 ± 67.6 kg were used. The cows w...
Herbage allowance effects on the characteristics of Brachiaria brizantha cv. Ma...
Dias, Alexandre Menezes; Gomes, Eva Nara Oliveira; Ítavo, Luís Carlos Vinhas; Aranha, José Aparecido Moura; Ítavo, Camila Celeste Brandão FerreiraThis study aimed to evaluate the effect of three herbage allowances (5, 10, and 15 kg dry matter [DM] 100-1 of body weight [BW]) for Brachiaria brizantha cv. Marandu pastures in a continuous grazing system on the morphological and nutritional characteristics of forage, animal performance, and economic viability in Nellore heifers. The total experimental area was 60 ha, divided into 12 paddocks of 5 ha each, wit...

Sugar cane treated with calcium hydroxide in diet for cattle: intake, digestibi...
Dias, Alexandre Menezes; Ítavo, Luís Carlos Vinhas; Damasceno, Julio Cesar; Santos, Geraldo Tadeu dos; Ítavo, Camila Celeste Brandão FerreiraThe objective of this work was to evaluate, in bovines, the intake and apparent digestibility of nutrients, ingestive behaviour and content of total digestible nutrients (TDN) of diets based on sugar cane treated with calcium hydroxide. It was used four cows with average body weight of 412.06 kg ± 37.3 kg. The study included inclusion of calcium hydroxide at the doses 0, 8, 16 and 24 g/kg of sugar cane in natur...
