ABSTRACT.
The massive use of pesticides and herbicides to increment the agriculture production can produce severe environmental impacts. This implies the need of new methods to monitor and control the use of chemical agents.An alternative to traditional sampling methods is the use ofinsects to act as a biological distributed sensor in order to monitor the presence of pesticides in the neighbourhood. Specifically, several authors have proposed the use of the beehive as a distributed sensor. To evaluate critical changes in the beehive behaviour, the sound patterns are analysed. In this work the guidelines used to develop a remote monitoring system in order to detect abnormal changes in the sound patterns in hives are presented. The evolution of the frequency spectrum sampled in four temporal windows is proposed to monitor the beehive health. Experiments to determinate the frequency band and the frequency resolution are presented for the case of Apis mellifera. Using these guidelines a complete monitor system was developed and constructed.

Abstract:
To investigate the immediate and long-term performance effects of milking frequency during early lactation of primiparous dairy cows consuming a total mixed ration and pasture, 20 Holstein cows were assigned in a randomized block design to either once-daily (1×) or twice-daily (2×) milking during the first 8 wk of lactation (treatment period). After the treatment period, all cows were milked 2× until wk 43 of lactation. Cows were fed a total mixed ration (approximately 15 kg of DM/cow per day) and allowed to graze an oat pasture (Avena sativa). Dry matter intake was 19.1 kg of DM/cow per day on average and was not affected by treatments. Milk yield was 40% lower in cows milked 1× during the treatment period, and a carryover effect existed until wk 21 of lactation, resulting in a final reduction of 15% of milk yield in the whole lactation. Milk lactose concentration decreased, whereas fat and protein concentrations increased for cows milked 1×. Mobilization of energy reserves during the treatment period occurred in both groups, but cows milked 1× showed greater body condition score and greater backfat thickness. In conclusion, milking 1× during the first 8 wk of lactation resulted in immediate and carryover negative effects on milk and milk solid yield without affecting feed intake, resulting in the improved energy status of primiparous dairy cows. |
