| Abstract: Identifying efficient animals is an alternative for reducing food costs. The objective of this study was to identify if the Residual Feed intake (RFI) is related to Permanence Time in the Trough (PTT) of Nellore cattle created in confinement using the Intergado® system. The work was realized at Embrapa Arroz e Feijão, in 39 bulls aged between 18 and 21 months and initial weight of 455 kg. The diet was given twice daily, with the voluminous ratio: concentrate of 60:40. The animals were ranked in more negatives than the most positive for RFI. The statistical comparison for PTT and RFI were made by the Tukey test at 5% probability. The difference between the less and larger animal RFI represented a consumption of 0.240 kg DM/day. For RFI, it checked... |

| A soja geneticamente modificada resistente a insetos e tolerante ao glifosato (MON 87701 × MON 89788), contendo o gene Cry1Ac, tem como principais alvos as lagartas desfolhadoras Pseudoplusia includens (Walker) e Anticarsia gemmatalis Hübner (Lepidoptera: Noctuidae). Em algumas regiões, Rachiplusia nu (Guenée) também pode ser uma importante praga, como no Rio Grande do Sul e sul do Paraná. Portanto, estudos sobre a variabilidade espacial e temporal de respostas à toxina Cry1Ac de populações destas espécies são essenciais para a realização de monitoramento da suscetibilidade, contribuindo para o futuro manejo da resistência. Populações de P. includens (n= 14) e A. gemmatalis (n= 7) foram coletadas nas safras 2008/09 a 2010/11, e uma população de R. nu foi... |

| Abstract: Identifying efficient animals is an alternative for reducing food costs. The objective of this study was to identify if the Residual Feed intake (RFI) is correlated with animal performance traits in Nelore cattle confined in the Intergado® system. The work was realized at Embrapa Arroz e Feijão, in 39 bulls aged between 18 and 21 months and initial weight of 455 kg. The diet was given twice daily, with the voluminous ratio: concentrate of 60:40. The descriptive statistics analysis and the Pearson correlations for the traits under study were performed using the Statistical Analysis System software (version 9.0). Note that the RFI has higher CMS and EA correlation (0.43 and -0.26), due to the CMS calculation formula. The correlation of RFI with PI,... |

| Abstract: The aim of this research was to evaluate the genetic values obtained using genetic mating based on the means between the parent?s expected progeny differences (DEPs) (scenario I) and the optimized genetic mating (scenario II). Inbreeding coefficient (F), total genetic merit (MGT), farmer genetic merit (MGC) and the predictions of DEP for probability of precocious pregnancy (D3P), age at first calving (DIPP), accumulated productivity (DPAC), scrotal circumference at 365 and 450 days of age (DPE365 and DPE450), stayability (DSTAY), maternal ability at 120 and 210 days of age (DMP120 and MP210), weights at 120, 210, 365 and 450 days of age (DP120, DP210, DP365 and P450), rib eye area (DAOL) and backfat thickness (DACAB) were analyzed in this study.... |

| The objective of this study was to verify the correlation of residual feed intake, gain and body weight variables obtained by traditional weighing methods and daily weighing using an automated scale, in feed efficiency tests, also verify the feasibility of reducing the duration of the test using the automated system, identifying the amount of minimum and adequate days for accurate measurement of residual feed intake, weight gain, dry matter intake and ratio conversion. The number of bulls used was 44, not castrated and aged between 18 and 21 months. The test had a duration of 70 days, with an initial weighing, four intermediate and final weighing. The animals were also weighed daily by means of electronic scales coupled to drinking fountains. The variables... |
