Greetings,
Very interesting article, there is a marked effect of "summer" on the studied parameters being less noticeable in the region of Galicia, in the region of Valencia the effect is more marked in spite of having the cows cooling systems. The low conception rates (<10%) in the summer season in the Valencia region are striking. In general, the indicators are more stable throughout the year in the region of Galicia, it would be necessary to analyze in detail the predominant feeding and management systems in each region.
