The Rhipicephalus microplus tick is one of the main sources of losses in tropical cattle production, causing decreased performance, hide devaluation, and increased costs with treatments and transmission of infectious agents. The aim of this work was to evaluate the utility of genomic evaluation of Braford and Hereford cattle for genetic resistance to ticks. Repeated tick counts were obtained in 2010 and 2011 from 3,114 Braford and Hereford cattle from 7 herds of the ?Delta G Connection? breeding program, totalizing 8,004 records. A sample of 1898 Braford and 262 Hereford animals was genotyped using Illumina BovineSNP50 Beadchip. Averaged and log-transformed records were combined with pedigree and genotypes to carry out single step genomic evaluation using BLUPf90 programs. Heritability of tick counts was estimated to be 0.42 ± 0.05, with a 75% increase compared with the estimate based on traditional pedigree evaluation (0.24 ± 0.06). Finally, data was split into 8 subsets (7 Braford and 1 Hereford) for a cross-validation study. Correlation between genomic predictions from the cross-validation and from full data analyses were 0.61 ± 0.13 and 0.47 ± 0.05, respectively for Braford and Hereford animals. These results indicate that genomic selection could be used as a reliable tool to improve genetic progress for resistance to ticks in these breeds and to obtain resistant lines of cattle raised at South America. |

RESUMO - Num experimento de laranja Valência (Citrus sinensis Osbeck), em solo arenoso e ácido, com aplicação de quatro níveis de adubação com N, três níveis com P e quatro níveis com K, avaliaram-se os efeitos destas adubações sobre a concentração foliar de nutrientes. A concentração de N e Cu nas folhas foi excessiva, e a de P e Zn, baixa. Doses crescentes de N, P2O5 e K2O aumentaram a concentração foliar de N, P e K, respectivamente. Doses crescentes de N aumentaram a concentração foliar de Mn e reduziram a de Ca. Teores foliares de P e K correlacionaram positivamente. Maior disponibilidade eçãde K reduziu a concentração foliar de Mg e Ca. ABSTRACT - In a field experiment of Valencia orange (Citrus sinensis Osbeck) growing in a sandy acid soil, with 4 N, 3 P and 4 K fertilizer levels, the effects of NPK fertilization on the nutrient concentration in the leaves was evaluated. N and Cu contents in the leaves were high, while P and Zn levels were low, in all treatments. Increasing the levels of N, P 2 05 and 1(20 fertilization resulted in an increase of the N, P and 1< concentration in the leaves, respectively. Crescent levels of N fertilization raised Mn and decreased Ca concentration in the leaves. P and K contents in the leaves correlated positively. With a great availability and absorption of K, reduction on the foliar contents of Mg and Ca occurred. |
