Abstract:Three years pesticide residues monitoring data in pollen, wax, bees and honey from sentinel apiaries in different agroecosystems in Uruguay were used for meta analysis. Support vector machines (SVM) algorithm was used previously to classify environments and is the basis of the present work. An useful indicator was developed to classify the contamination status of both beehives and associated environment. The index is a quotient between hive simple demographic parameters and the sum of toxic units for each pesticide found in it. The Agroecology Environment Quality quotient (AEQ) can be scaled in three different levels. When it is below 1, the hive will hardly develop in such environment. AEQ values between 1 and 2 indicate that the hive could have some restrictions to develop in such environment due to pesticide contamination but probably it will be productive. In the cases where the index is above 2, the hive will develop well in the environment where it is located. AEQ permits simultaneously to obtain different information. These are: the surveillance of good agricultural practices accomplishment in agroecosystems, the selection of the best environment to perform apicultural activities as well as to monitor the productivity and development of the beehives. |

Abstract:
Eimeria bovis, Eimeria zuernii, Eimeria ellipsoidalis, Eimeria auburnensis, Eimeria canadensis and Eimeria alabamensis were identified on different dairy farms in Uruguay. The most prevalent species were E. bovis and E. zuernii, which were mainly found in the feces of calves with diarrhea. The dynamics of oocyst excretion were evaluated via the weekly determination of oocysts per gram (OPG) values in fecal samples from 97 calves over seven months. Three groups of calves were formed according to their age in days: Group 1 (1?20 days old), Group 2 (21?40 days old) and Group 3 (41?65 days old). In Group 1, the median OPG was zero, and the maximum OPG was 1,680. In Group 2, the median OPG was between zero and 8,240, and the maximum OPG was 428,800. In Group 3, the median OPG was between zero and 220, and the maximum OPG was 16,000. For the evaluation of the relationship between OPG and age group, a proportional odds model was built. Two samples from 60 bovines evaluated in Group 2 and in Group 3 were selected. OPG was categorized as negative, moderate (lower than or equal to 4,000) or high (greater than 4,000). Calves of Group 2 (21?40 days old) were significantly (p < 0.001) more affected by eimeriosis than calves of Group 3 (41?65 days old). Considering that diarrhea in calves is a multifactorial disease, eimeriosis should be considered when evaluating the control measures for diarrhea syndrome, particularly in calves of 21?40 days of age. |
