The transformation of the soybean [Glycine max (L.) Merril] cultivars BR-16 and Doko with the gene AHAS isolated from Arabdopsis thaliana resulted on the development of genotypes tolerant to imazapyr. In order to compare the conventional genotypes BR-16 and Doko (no sprayed) with their transformed counterparts (sprayed with imazapyr 100 g ae/ha) a trial was conducted in the greenhouse in the winter of 2001 (sowing occurred in july 2001). At harvest, the plants were divided in three thirds and the number of pods and seeds counted, the seeds weighted and the average number of seeds per pod determined. The genotype BR-16-AHAS was much more affected than Doko-AHAS when the genotypes were compared with their conventional counterparts. Since that the effect of the gene AHAS and the effects of the herbicide could not be separated, another experiment, only with the two AHAS genotypes (BR-16-AHAS and Doko-AHAS) and the application of zero and 100 g ae/ha of imazapyr during the summer (seeding occurred in December 2001) was conducted. The same observations made in the winter experiment were made and also, the height of the plants and the number of nodes were recorded. In this trial, the relative responses of the two genotypes were similar to the winter results, but the herbicides effect differed mainly on the most affected position in each genotype. Doko in the summer produced fewer pods in the medium third and, in the winter, in the upper third. The herbicide imazapyr applied on the dosage of 100 g ae/ha on transformed tolerant soybean with the AHAS gene may induce the development of sterile pods, mainly on the nodes located on the upper parts of the plants. The effect is due to the herbicide and not to the inserted gene and is more visible in winter conditions (lower temperatures and short-day conditions). This effect is very pronounced on BR-16 and less evident on Doko. Field trials should be done to evaluate the risks in commercial conditions. MenosThe transformation of the soybean [Glycine max (L.)

The objective of this study was to analyze the correlation between milking characteristics and the behavior of cows in automatic milking systems. Data were collected between September 2019 and March 2020 from two commercial dairy herds located in Minas Gerais, Brazil, which use an automatic milking system (AMSTM, DeLaval, Tumba, Sweden). The dataset comprised 68,896 observations from 542 primiparous and multiparous cows of Holstein and crossbred (Holstein × Jersey) breeds. Daily milking characteristics, including milk flow rate (FR), time spent in the milking box (BT), and milking efficiency (ME), were recorded, along with behavioral traits such as milking handling time (HT), incomplete milkings (IM), and kicks. To assess the relationships between these traits, a bivariate correlation analysis was performed using Pearson?s correlation coefficient, executed with the statistical software SPSS version 22. The results revealed moderate negative correlations between FR and BT, ME and HT, and BT and ME. Conversely, a strong positive correlation was observed between FR and ME. A high positive correlation was identified between BT and HT, a moderate positive correlation between ME and milk yield, and a weak positive correlation between HT and IM (P<0.01). No significant correlation was found between milking frequency and kicks or incomplete milkings. |
