“…Rumination was discovered to be voluntarily regulated by the animals, and if they were distracted in any way, such as when they were being milked or fed, they would discontinue ruminating (Beauchemin, 2018;Paudyal, 2021). The Jersey dairy cattle in this study ruminated more without music than when music was played.…”

The influence of music on the milk performance of dairy cattle has been increasingly studied in recent years, although its efficacy is still being debated due to the inconsistent outcomes and a limited number of studies. This study aimed to investigate the impact of music on the milk production and behaviour of 24 lactating Jersey cattle, consisting of 10 primiparous and 14 multiparous cows. The experiment involved milk collection and behavioural observation before and after exposure to music at a dairy farm in Sitiawan, Perak. The results indicate that music and parity significantly affect the milk yield produced by a cow at p < 0.05. The cows produced significantly less milk after being exposed to music, while multiparous cows recorded significantly higher milk yields than primiparous cows. In terms of the observed behaviour, the cows displayed a significantly higher proportion of feeding and ruminating when no music was played. On the other hand, multiparous cows displayed a significantly lower proportion of feeding and ruminating, and a higher proportion of standing compared to primiparous cows. However, no significant effects of parity and music were observed in walking and lying behaviour. To conclude, music did not improve the milk yield of Jersey dairy cows in this study. Due to the inconsistencies in the outcomes of many studies related to the effect of music on milk yield, more long-term research should be conducted by considering factors that might influence milk yields, such as parity, breed, housing environment, and music selection.

“…As rumination impacts the intake and utilization of the diet, it directly correlates to productivity and health [ 10 , 37 , 142 , 155 , 162 , 181 ]. Therefore, it is often used as a proxy to measure dairy cattle health and welfare [ 47 , 101 , 156 , 160 , 164 , 169 , 173 , 181 , 182 ]. For example, in a meta-analysis, decreased rumination was a good predictor of metritis but not subclinical ketosis [ 181 ].…”

“…For example, in a meta-analysis, decreased rumination was a good predictor of metritis but not subclinical ketosis [ 181 ]. Additionally, the rumination behavior can also be used as an indication of physiological changes such as calving or estrus [ 101 , 126 , 169 , 179 , 182 ]. Even slight changes in rumination (time spent on rumination or number of chews per cud) can be used as indicators of a potential subclinical problem with the diet, and actions can be taken before they become clinical [ 35 , 101 , 160 , 169 ].…”

The Value of ‘Cow Signs’ in the Assessment of the Quality of Nutrition on Dairy Farms

The aim of this review is to provide dairy farm advisors, consultants, nutritionists, practitioners, and their dairy farmer clients with an additional toolkit that can be used in the assessment of the quality of their dairy cattle nutrition. Cow signs are behavioral, physiological, and management parameters that can be observed and measured. They are detected by examining and observing the cattle. Other physiological parameters such as fecal scoring, rumen fill, and body condition scoring are also included in ‘cow signs’. The assessment should be both qualitative and quantitative; for example, is the cattle individual lame and what is the severity of lameness. The ‘diagnosis’ of a problem should be based on establishing a farm profile of ‘cow signs’ and other relevant information. Information gathered through assessment of cow signs should be used as an advisory tool to assist and improve decision making. Cow signs can be used as part of an investigation and or farm audit.

“…The rumination time (RT) is mainly related to diet composition (Beauchemin, 2018). However, the reduction in RT may also be related to the stress that the dairy cow is experiencing (Paudyal, 2021). The MY can be interpreted to be a direct welfare indicator (Polsky and von Keyserlingk, 2017).…”

This study aimed to evaluate the relationship between temperature (T), relative humidity (RH), and temperature and humidity index (THI), milk yield (MY), rumination time (RT), and activity (AT) of dairy cows in different parities under low temperature and high humidity (LTHH). In this study, the number of samples each day was determined by all healthy cows in the barn with parity and days in milk (DIM) within 5 and 305, respectively. The box plot method was used for screening and removing outliers of dairy cow indicators after classification according to parity and DIM. To remove the effect of DIM on MY, a bivariate regression model was used to standardize the MY in milk yield index (MYI). The best bivariate regression model based on the lowest Akaike information criterion was used to analyze the relationship between behavioral parameters, MYI, and microclimate indicators for each parity. In the barn with the microclimate at a low temperature above 0°C, high RH was negatively correlated with MYI in primiparous and multiparous cows but positively correlated with AT in primiparous and multiparous cows and RT in multiparous cows (p < 0.05), so RH was a significant factor related to MYI, RT, and AT of cows. The 2-day lagged daily average T and THI were correlated with MYI in primiparous cows (p < 0.05). The inflection point value of 71.9 between AT and RH in the multiparity as the upper limit of RH was beneficial for improving comfort and MY in all parity dairy cows. Compared with MYI and RT, AT had a higher R2 with a microclimate indicator, so it could be used as a better indicator for assessing the LTHH. Comparing the R2 of multiparous cows to T (R2 = 0.0807) and THI (R2 = 0.1247), primiparous cows had higher R2 in MYI to T (R2 = 0.2833) and THI (R2 = 0.3008). Therefore, primiparous cows were more susceptible to T and THI. The inflection point values for MYI to T and THI were greater in primiparous cows than in multiparous cows, indicating that primiparous cows had a smaller tolerance range to T and THI than multiparous cows. Thus, parity should be considered when studying the relationship between MY, T, and THI under LTHH.
