Autoria: TORTORELLA, R. D.; TEIXEIRA, H. C. A.; MODESTO, M. R; NEVES, J. P.; RAMOS, A. F. Conteúdo: The aim of this study was to determine the effect of equine chorionic gonadotropin (eCG) on follicular dynamics in a FTAI protocol. Twelve single cows with a mean body condition score (BCS) of 3 (1-5) were maintained in grazing conditions (Brachiaria decumbens) with ad libitum water and mineral supplementation.

Autoria: BRASIL, O. O.; MOREIRA, N. H.; SANTOS JÚNIOR, G.; SILVA, B. D. M.; RAMOS, A. F. Conteúdo: This study aimed to evaluate the effect of exogenous progesterone time exposure during supertimulation, with or without the addition of GnRH agonist on embryo yields in Santa Inês ewes. Forty-eight embryo donors were synchronized with intravaginal progesterone device (CIDR).

Autoria: VALLS, J. F. M. Conteúdo: Brazilian forage breeding programs are below the needs for a country of continental dimensions. They target too few species, and grass cultivars are mostly exotic. The main forage cultivars resulted of phenotypic selection based on agronomic merit, and, just a short time ago, this kind of selection would depart from very small collections. Present trends include acceptance of the value of broad collections, a clear concern on the mode of reproduction, potential introgression of genes from allied species, and a drive for greater use of native species, mostly of the legume genera Arachis and Stylosanthes, but also of Paspalum. Results of such programs are reaching the market, yet at long intervals. Expanded use of native species finds obstacles on lack of information, and frequently on reproductive barriers, to be overcome by cytogenetic studies and pre-breeding activities, that still need to capture the breeder’s attention. Many native grasses and legumes have a potential for use as cultivars. For centuries, native plants have been the biological basis for sustainable livestock raising in many Brazilian states. There is a good insight on which species are the main components of productivity in Brazilian natural pastures. Accessions of many native species are now available in genebanks, in spite of their rarity in breeder’s working collections. Identification of elite species has been recently stressed, under the “Plants for the Future” governmental project, especially concerning the Southern and West Central Brazilian regions. Initiatives involving outstanding native legumes and grasses will be commented. While in exotic germplasm, the search for expanded knowledge on reproductive mechanisms aims at the incorporation of such knowledge in breeding strategies, the search for biosystematic knowledge of native species has dual purpose: The sustainable management of native pastures, considering the adequate conservation of major components of their yield and environmental services, and balanced survival of plant populations with distinct ecological niches, and the use of such knowledge in pre-breeding activities and breeding programs. Identification of limiting factors for the establishment of a broad span of native cultivars of forage grasses and legumes, adapted to the diverse ecological conditions of the Brazilian territory, will help to find a better niche for native species in the spectrum of commercial forage plants for sustainable pasture establishment.

Autoria: CHEN, S.; LI, K.; CARVALHO, L. J. C. B. Conteúdo: In this study proteomics provides a broad view of cassava varieties at the level of proteins. It is intended to give an understanding of the technologies behind proteomics and its application to address biological questions regarding source-flux-sink interactions, high starch accumulation, nutritional-quality characteristics and etc. Sun, 01 Jan 2012 00:00:00 GMT https://www.alice.cnptia.embrapa.br/alice/handle/doc/1187390 2012-01-01T00:00:00Z
