“…The PMR eating rate found in our study was higher than that found in the study by Bach et al (2007), in which cows were given a high concentrate allowance. However, the result of eating rate in our study was comparable with other studies with a similar stocking density at the feed bins (Azizi et al, 2010;. Thus, a tight time budget might exist because the cows in our study might have increased their eating rate due to limited time for eating (Nielsen, 1999) because of the rather high stocking density.…”

The aim of this study was to investigate the effects of a concentrate strategy based on the individual cow partial mixed ration (PMR) intake compared with a flat rate. Half of the cows were fed the individual concentrate strategy, whereas the other half were fed the control strategy. The individually fed cows were offered a concentrate proportion equal to 30% of the ad libitum intake of the PMR in the automatic milking system, and the control cows were offered 3 kg of concentrate/d in the automatic milking system. The cows (83 Holstein and 64 Jersey), kept in 2 separate groups, were blocked between the treatments according to expected calving date, breed, and parity and were randomly divided between treatments. Lactation was divided into 3 periods (early, mid, and late lactation), and the MIXED and GLIMMIX procedures in SAS (SAS Institute Inc., Cary, NC) were used to analyze the production and behavioral responses. The response trajectories during lactation were analyzed with a MIXED procedure fitted by Wilmink parameters. The individually fed cows had a higher concentrate intake and a lower PMR intake than control cows. Moreover, the total dry matter intake and energy-corrected milk yield did not differ between concentrate strategies. The actual average concentrate intake reached 19% of the PMR intake during mid lactation and not 30% of the PMR intake, as intended with the strategy. This was due to leftovers and lower allocation than intended. The cow behavior did not differ between concentrate strategies. However, variation in PMR intake and eating rate between cows fed individually was lower during mid lactation and lower for lying bouts during early lactation compared with control cows. This may indicate that an individual cow concentrate strategy results in a more stable PMR intake and time budget, which potentially could improve welfare, but this needs further investigation. The overall conclusion is that the cows were robust to adjustments in the concentrate allowance.

“…The conducted regression analyses verified these estimations with high significant (P<0.001) results (R²=0.8). These results show stronger correlations then published in previous studies (Azizi et al 2010, Kaufmann et al 2007. Differences can be caused by the use of DM intake in the cited studies while we used fresh matter intake as dependend variable.…”

The objective of this study was to describe and compare circadian pattern of feed intake and feeding behaviour in healthy and diseased dairy cows. Test animals (n=138) were separated into two groups according to their health status. Health and management data were used to exclude cows with clinical or subclinical diseases. Fifteen cows of the test herd complied with the defined criteria and formed the reference group »healthy«. The behaviour of the remaining 123 cows was compared with the reference group. Both groups were used to analyse the feed intake and feeding behaviour on a daily base and in the course of 24 h. During a defined time range from day 28 post-partum to day 56 post-partum behavioural differences within these groups were analysed. There were no significant differences in daily feed intake (40.7 vs. 41.9 kg fresh matter per day, P=0.42). However, feeding behaviour pattern differed between the two groups (daily feeder visits, daily feeding time, number of daily feeder visit, number of daily meals, meal duration, feeding time within a meal, feeder visits per meal). For example, average feeder visit was shorter in the group with subclinical/ clinical health disorders than in the reference group (7.2 vs. 8.1 min, P=0.024). Differences in circadian feeding behaviour could be detected by analysing the feed intake and feeding time over the course of the day. Linear regression analyses showed strong correlations between feeding time and feed intake on hourly base (R²=0.8) and on daily base (R²=0.7).

“…Therefore, the differences we observed in traits associated with visits may disappear if the same analysis was performed on the basis of meals. Recent studies showed that eating rate was affected by animal characteristics such as parity (Azizi et al, 2009 and, MY level (Azizi et al, 2009), lactation stage (Abrahamse et al, 2008;Azizi et al, 2010) and diet composition (Baumont, 1996;Friggens et al, 1998;Abrahamse et al, 2008). Thus, in our study, we observed that eating rate could be affected by the haplotype at one QTL-F-Fert-BTA3.…”

animal Significant differences in fertility between dairy cows selected for one QTL located on bovine chromosome 3 are not attributable to energy balance, although eating behaviour is affected S. Coyral-Castel 1,2,3,4,5 , P. Faverdin 6,7 , C. Ramé 1,2,3,4 , S. Fré ret 1,2,3,4 , D. Guillaume Improvement of reproduction in dairy cows has become a major challenge in dairy production. We have recently shown that dairy cows carrying the 'fertil2' haplotype for one quantitative trait locus (QTL), affecting female fertility and located on the bovine chromosome 3, had a significantly lower conception rate after the first artificial insemination than cows carrying the 'fertil1' haplotype. The objective of this paper was to study other phenotypic modifications linked to this QTL. In the present study, 23 'fertil1' and 18 'fertil2' cows were characterized for live weight, milk production, food intake, eating behaviour and plasma metabolites. These parameters were measured during the first lactation, from calving to 40 weeks postpartum (wkpp). In the first 7 weeks of lactation, 'fertil1' primiparous cows had a significantly higher live BW and milk production than 'fertil2' cows. Dry matter intake tended to be slightly higher for 'fertil1' than for 'fertil2' primiparous cows in this period. However, energy balance was similar for the two haplotypes in the whole lactation, except in the first wkpp, and consequently, could not explain their different fertility. The major observation concerned the eating behaviour. 'Fertil1' primiparous cows had a significantly lower eating rate than 'fertil2' cows during the 40 weeks of lactation. In parallel, 'fertil1' cows spent significantly more time at the feeder for a similar number of visits than 'fertil2' cows. Furthermore, no differences in plasma concentrations of non-esterified fatty acids and insulin were observed between the two haplotypes. Plasma glucose was significantly lower in 'fertil1' than in 'fertil2' cows in the second wkpp. Taken together, our results show that 'fertil1' and 'fertil2' dairy cows, with different fertility, have also different eating behaviour without any variation in energy balance, except in the first week of lactation.Keywords: dairy cow, eating rate, quantitative trait locus, metabolite ImplicationsThe fall in dairy cows' fertility is related, in part, to the strong genetic selection for milk production. It has been shown that several bovine Quantitative Trait Loci (QTL) affected female fertility. However, other physiological roles of these QTLs are not clearly established. As the effect of a high milk production is associated with the negative energy balance at the beginning of lactation (high needs for energy and limited postpartum feed intake), we studied several zootechnical and metabolic parameters in dairy cows carrying contrasting haplotypes at one female fertility QTL located on the BTA3, and presenting a phenotypic difference in fertility. These experiments are of particularly strong interest with the development of genomic selection.
