Development and validation of an objective method for the assessment of body condition scores and selection of beef cows for timed artificial insemination. Author(s): PFEIFER, L. F. M.; CASTRO, N. A.; NEVES, P. M. A.; CESTARO, J. P.; SIQUEIRA, L. G. B. The objectives of this study were to: 1) evaluate the relationship of the angle formed between the left and right sides of the rump with body condition score (BCS) in cattle; and 2) develop an objecti... ...

Selection index as a priori information for using artificial neural networks to classify alfalfa genotypes. Author(s): FERREIRA, R. de P. The efficiency of a selection index generally depends on the quality of the variance matrixes, which demands controlled experiments. Using Artificial Neural Networks (ANNs) trained from a selection in... ... Repository: BDPA Publication year: 2019
Production and disease resistance of elite black bean lines previously selected using mineral nitrogen fertilization cultivated with natural versus artificial nitrogen supplementation. Author(s): MELO, L. C.; SOUZA, T. L. P. O.; FARIA, L. C. de; FERREIRA, E. P. B.; PEREIRA, H. S. Nitrogen (N) is the most important soil nutrient for common beans; the main sources are mineral N fertilizers and symbiotic N fixation (SNF). The common bean (Phaseolus vulgaris) is a N fixing species... ... Repository: BDPA Publication year: 2020
Identification of selection signatures in livestock species. Author(s): SILVA, M. V. G. B.; PAIVA, S. R. The identification of regions that have undergone selection is one of the principal goals of theoretical and applied evolutionary genetics. Such studies can also provide information about the evolutio... ... Repository: BDPA Publication year: 2014
Molecular evolution and signatures of selective pressures on Bos, focusing on the Nelore breed (Bos indicus). Author(s): REGITANO, L. C. de A. Evolutionary history leads to genome changes over time, especially for species that have experienced intense selective pressures over a short period. Here, we investigated the genomic evolution of Bos... ... Repository: BDPA Publication year: 2022
Genetic diversity and population genetic structure of a Guzerá (Bos indicus) meta-population. Author(s): PEIXOTO, M. G. C. D.; EGITO, A. A. do; BRUNELI, F. A. T.; MACHADO, M. A. The Brazilian Guzerá population originated from a few founders introduced from India. These animals adapted well to the harsh environments in Brazil, were selected for beef, milk, or dual-purpose (bee... ... Repository: BDPA Publication year: 2021
The effects of the insecticide lambda-Cyhalothrin on the earthworm Eisenia fetida under experimental conditions of tropical and temperate regions. Author(s): GARCIA, M. V. B.; GARCIA, T. B. Plant Protection Products can affect soil organisms and thus might have negative impacts on soil functions. Little research has been performed on their impact on tropical soils. Therefore, the effects... ... Repository: BDPA Publication year: 2011
Inseminação artificial em ovinos. ABSTRACT: The aim of this review is to show and illustrate an way clear and objective of the aspects involved in the artificial insemination in sheep. In this species the potential is great, therefore... ... Repository: BDPA Publication year: 2006
Genomic prediction of leaf rust resistance to Arabica coffee using machine learning algorithms. Author(s): CAIXETA, E. T. Genomic selection (GS) emphasizes the simultaneous prediction of the genetic effects of thousands of scattered markers over the genome. Several statistical methodologies have been used in GS for the p... ... Repository: BDPA Publication year: 2021
Antral follicle count classification selects fertile heifers without influencing the carcass traits. Author(s): GHELLER, J. M.; SILVA, G. C. da; SILVA, W. A. L. da; SILVA, A. F. da; COSTA FILHO, L. C. C.; NOGUEIRA, E.; MELO-STERZA, F. de A. This study aimed to evaluate the ovarian structure, estrus intensity, ultrasound carcass measurements, and pregnancy rate of Nelore breed heifers and cows in accordance with antral follicle counts (AF... ...
