Abstract The objective of this study was to examine associations between milking temperament, parity and milk production traits in primiparous and multiparous dairy cows. Twenty-one primiparous and nineteen multiparous Holstein Friesian cows were involved in the investigation on a Hungarian dairy farm. Cows’ stepping behaviour, milk yield and average milking speed were recorded once a month over an entire lactation, during morning milking. Milking temperament was scored by direct human observation on a 5-point-scale (1=very nervous, 5=very quiet) during udder preparation and milking. Multiparous cows showed a little more excitable behaviour at milking than during udder preparation (Mann-Whitney U=14165.00, P=0.032), and they were calmer at premilking preparation than primiparous cows (Mann-Whitney U=14046.00, P=0.001). Milking temperament of multiparous cows during udder preparation was associated with milking speed: nervous cows let down their milk slower (F=9.102, df= 1, P=0.003). Further experiments are needed to repeat the milking temperament test along with sensors measuring heart rate variability of cows in order to better understand the milking behaviour of cows.

The aim of this study was to evaluate the change of temperament of Holstein cows scored before and during milking during the entire lactation and to calculate correlation between temperament measured in the two moments as well as milk production traits and temperament. Observations were carried out on 17 primiparous Holstein Friesian cows starting their lactation within 85 days. Measurements of temperament and milk production traits were taken once in each month of the lactation, during the morning milking, in a milking parlour. Temperament was assessed in a 5-point scale during udder preparation and milking procedure (1: very nervous, 5: very quiet). Data of milk yield and milk flow were collected individually on each test day morning. Results showed changes during the lactation in temperament of cows scored directly before milking (P < 0.01), however, temperament during milking did not alter with months (P > 0.10). By correlation coefficients, behaviour assessed in the two moments cannot be regarded as the same. In addition loose, significant relations were found only between milk traits and temperament before milking.

Bovine mastitis is a widespread disease of the mammary gland, highly contributing to the increase in veterinary costs in dairy industry. In the present study, the genetic polymorphism within bovine L-selectin gene was analysed and its impact on clinical mastitis occurrence, somatic cell score (SCS), and milk production traits in Polish Holstein-Friesian cows was examined. Polymorphism within L-selectin gene, molecule responsible for neutrophil attachment to endothelium, might have a potential role in immune response to bacterial infections and udder health. Two hundred and six Polish Holstein-Friesian cows were genotyped by polymerase chain reaction-restriction fragment length polymorphism method. Two single nucleotide polymorphisms mutations within the coding sequence of L-selectin gene were identified (c.165G&gt;A and c.567C&gt;T). The effect of c.165G&gt;A and c.567C&gt;T mutations on SCS was highly significant (P = 0.0019 and P = 0.0003, respectively). Strong associations (P ≤ 0.0001) were also observed between L-selectin polymorphism and milk production traits (milk yield, milk fat percentage, and milk protein percentage). However, the polymorphism in the analysed gene had no influence on the resistance or susceptibility of cows to clinical mastitis (only the tendency toward significance, P = 0.06 for c.567C&gt;T mutation was found). Potential exploitation of the information on the identified associations in genetic selection needs to confirm the obtained results in further investigations.

SUMMARYTen dairy cows were allocated into three groups according to milk productivity (four high, four intermediate and two dry cows, respectively). Heat production and heart rate, but not rectal temperature, were significantly different (P < 0·05) between groups. Heat production increased during feeding in the morning and in the afternoon and reached a peak 3 h later. Minimum heat production was observed in the early morning before feeding. The diurnal pattern for heart rate reflected that of heat production. These results suggest that cooling dairy cows during hot summer days is most effective at feeding time and 3 h afterwards.

Two Phases

The heart rate variability (HRV) parameters of dairy cows were monitored during parlour (PARL) and the later installed automatic (AMS) milking on a small-scale commercial dairy farm in Hungary. The aim of the study was to assess stress in relation to the type of milking and the frequency of human interaction. Parlour milking involved regular moving and crowding of the animals with frequent human interaction, which were much less frequent in automatic milking. The first phase of the study was conducted prior to the changeover [n = 27] and the second two months afterwards [n = 19 (of the cows from the first phase)]. Heart rate (HR) was recorded by the Polar RS800 CX recording system. HRV parameters indicative of sympathovagal balance were calculated for periods of lying and standing in the barn, waiting before milking and milking, respectively. Morning and evening faecal glucocorticoid concentrations were also measured. Fear of humans was tested by an avoidance distance test. Baseline HRV parameters showed no difference (P > 0.05) between the two systems. In the periods before, during and after milking a higher sympathetic tone was detected in cows in the PARL phase. Mean faecal glucocorticoid concentrations were higher at the time of parlour milking. The avoidance distance did not differ between the two phases. The results suggest that automatic milking might be less stressful for cows than parlour milking, possibly due to the shorter duration of restraint after milking and the less frequent human interaction.

The objective of this study was to evaluate the relationship between the polymorphism within GHRH gene (GHRH/HaeIII) and milk production traits for Polish Holstein-Friesian using PCR-RFLP technique for genotyping. The molecular background of this mutation was defined as the A→C transversion at the intron 2. A total of 220 cows were examined. The following frequencies were established: 0.0227 for genotype AA, 0.3227 for AB, and 0.6546 for BB; 0.1841 for the allele GHRHA and 0.8159 for GHRHB. A highly significant association was found between the GHRH/HaeIII polymorphism and milk performance. The BB-genotype cows were characterised by a higher fat yield and percentage (P ≤ 0.01).
