The use of cubicle mats for dairy cows has been promoted on the basis that they encourage cubicle occupancy, thus improving hygiene, and reduce the incidence and severity of udder and leg injuries. It has also been suggested that cows are less stressed so that fertility and production performance is improved, thus increasing profitability. This experiment was carried out to study the effect of synthetic cubicle mats (Cow Comfort, Wigan) on dairy cattle behaviour, health and productivity.The first study used 33 cows offered a choice of 24 matted cubicles and 24 unmatted cubicles arranged in alternating groups of four. The cows were observed every half hour for 24 hours and their location (in or out of cubicles) and behaviour (standing or lying and whether ruminating) recorded. The second was a changeover experiment in which two groups of 28 cows were housed for two periods, each of at least two months, on either matted or concrete cubicles. In each period cow location and behaviour was recorded half hourly for a 24 hour duration. The 1·19 X 2·17 metre cubicles had Dutch Comfort divisions and all were bedded with sawdust. Cow health, reproductive performance and lameness were monitored throughout.

Holstein Dairy Cows

This study aims to characterize the influence of short-term heat stress (HS; 4 day) in early lactating Holstein dairy cows, in terms of triggering blood metabolomics and parameters, milk yield and composition, and milk microRNA expression. Eight cows (milk yield = 30 ± 1.5 kg/day, parity = 1.09 ± 0.05) were homogeneously housed in environmentally controlled chambers, assigned into two groups with respect to the temperature humidity index (THI) at two distinct levels: approximately ~71 (low-temperature, low-humidity; LTLH) and ~86 (high-temperature, high-humidity; HTHH). Average feed intake (FI) dropped about 10 kg in the HTHH group, compared with the LTLH group (p = 0.001), whereas water intake was only numerically higher (p = 0.183) in the HTHH group than in the LTLH group. Physiological parameters, including rectal temperature (p = 0.001) and heart rate (p = 0.038), were significantly higher in the HTHH group than in the LTLH group. Plasma cortisol and haptoglobin were higher (p < 0.05) in the HTHH group, compared to the LTLH group. Milk yield, milk fat yield, 3.5% fat-corrected milk (FCM), and energy-corrected milk (ECM) were lower (p < 0.05) in the HTHH group than in the LTLH group. Higher relative expression of milk miRNA-216 was observed in the HTHH group (p < 0.05). Valine, isoleucine, methionine, phenylalanine, tyrosine, tryptophan, lactic acid, 3-phenylpropionic acid, 1,5-anhydro-D-sorbitol, myo-inositol, and urea were decreased (p < 0.05). These results suggest that early lactating cows are more vulnerable to short-term (4 day) high THI levels—that is, HTHH conditions—compared with LTLH, considering the enormous negative effects observed in measured blood metabolomics and parameters, milk yield and compositions, and milk miRNA-216 expression.
