Abstract. The aim of this study was to analyse the effect of the temperament of cows on their lifetime production efficiency. Data on milk performance, longevity and culling reasons of 11 629 Polish Holstein-Friesian cows were extracted from the SYMLEK database. Using the methodology of the Polish Federation of Cattle Breeders and Dairy Farmers, cow temperament was assessed as follows: 1 – calm; 2 – normal; and 3 – excitable or aggressive. Most cows showed a normal temperament (89.52 %). Over successive years of the evaluation, there were increases in the proportion of cows with a calm (from 2.98 to 6.85 %) and excitable temperament (from 7.50 to 8.27 %). Temperament was found to have a highly significant effect on first lactation milk yield, first lactation daily milk yield, milk yield per day of age, and milk yield per day of productive life. In cows with a calm temperament, first lactation milk yield was 621 kg higher than in cows with a normal temperament and 329 kg higher compared to excitable (aggressive) cows.

The average somatic cell count in the milk analysed was 326,000 cells/ml. For the 4 groups of cows distinguished in the study, with daily milk yield of ≤15 kg, 15-25 kg, 25-35 kg and >35 kg, the somatic cell count was 771,000, 393,000, 240,000 and 180,000 cells/ml, respectively. Statistical analysis revealed significant differences in the somatic cell count in milk from cows with different productivity. A highly significant correlation coefficient was obtained for the daily milk yield of the cows and the somatic cell count in the milk (r=−0.81). The negative coefficient indicates that an increase in the quantity of milk was accompanied by a decrease in the somatic cell count in the milk. The regression equation obtained suggests that in the study population a decline in somatic cell count of 100,000 cells/ml was accompanied by an increase in daily milk yield of 3.8 kg. The analysis showed that there is a negative correlation between SCC and milk yield of cows. An increase in milk yield was found to be accompanied by a decrease in the number of somatic cells in 1 ml of milk, which indicates an improvement in its quality.

As a major health problem facing dairy farmers worldwide with substantial economic, production and welfare consequences, lameness has attracted much attention over the last two to three decades (Boelling, 1999). Lameness as a linear type trait is measured by locomotion scoring as there is a high genetic correlation between lameness and locomotion score. Studies have included locomotion (as a predictor of lameness) and have associated lameness with no effect, an increase and sometimes a decrease in milk production of cows. Several reasons have been given for these differences and the need still arises for estimates of the effect of lameness on milk yield in herds with current dairy management. The objective of this study was to quantify the effect of lameness on the daily milk yield (DMY) of dairy cows.

The aim of this study was to determine the reproductive characteristics, milk yield and milk quality of Primiparous Red-Holstein (RH) and Holstein-Friesian (HF) cows. For this aim, records and monthly taken milk samples of 83 RH and 14 HF raised on a farm in Aydın, Turkey were used. The averages of the first calving age (FCA), gestation length (GL), days open (DO), calving interval (CI), daily milk yield (DMY), 305-day milk yield (305-dMY), solid non-fat (SNF) and Log10 somatic cell count (Log10SCC) of milk were found to be 27.6±0.24 mo, 278.4±1.09 d, 144.0±7.12 d, 421.4±7.66 d, 22.7±0.21 kg, 6981±137.0 kg, 9.8±0.04% and 4.59±0.024 (38905 cells/ml), respectively. Except for DMY, the differences between the breeds were statistically insignificant for FCA, GL, DO, CI, 305-dMY, SNF and Log10SCC. DMY averages for RH and HF were 21.8±0.21 kg and 24.3±0.49 kg, respectively. The effect of season on FCA and the effect of lactation month on SNF and Log10SCC were also found to be statistically significant. Apart from DMY, not any significant difference was observed between RH and HF breeds in terms of the characteristics emphasized.

Abstract. The aim of present study was to investigate the relationships between temperament score and milk production, as well as somatic cell count in a herd of Jersey and Holstein Friesian breeds. The temperament of 283 Jersey and 69 Holstein Friesian cows were assessed (scored) by the temperament score test (behaviour of animals was assessed in a 5-score system (1: calm, 5: nervous) while spending 30 s on the scale during weighing). The daily milk yield, fat, protein content and somatic cell count were also investigated in this study. Our investigation did not reveal any correlation between daily milk yield and temperament score. But milk somatic cell count was showed positive moderate relation with the temperament scores of Jersey (rrank=0.67; P=0.0001) and Holstein Friesian (rrank=0.66; P=0.0001) cows. Calmer cows had lower somatic cell count (Jersey: 135.40×103/cm3; Holstein Friesian: 176.07×103/cm3) compared to the more temperamental cows (Jersey: 540.44×103/cm3; P=0.0001; Holstein Friesian: 744.91×103/cm3; P=0.0001, resp.).

ABSTRACTTwo experiments were conducted to compare the effects of single and double suckling on the performance of Hereford × Friesian and Friesian cows at pasture. Double-suckled cows each fostered a Friesian male calf in addition to their own calf. Cows were housed from calving to turnout for 57 and 35 days in experiments 1 and 2 respectively, with corresponding grazing seasons lasting 152 and 146 days. During the grazing season the two suckling treatments were stocked on a series of adjacent plots of equal area, with the occupancy of each plot pair being reversed daily. Live weights, milk yields, herbage intakes, and daylight grazing times and nursing activities were recorded on three occasions 28 days apart.Double-suckled cows lost significantly more weight than single-suckled cows from calving to turnout in both experiments (39·5 v. 3·3 kg and 45·7 v. 20·6 kg), gained more weight from turnout to weaning in experiment 1 (58·4 v. 23·3 kg) but gained less in experiment 2 (17·5 v. 32·3 kg). Double-suckled cows produced significantly more milk than single-suckled cows: 10·1 v. 8·3 and 13·5 v. 9 1 kg/day in experiments 1 and 2 respectively. Differences in daily milk yield in experiment 2 were apparent 28 days after calving.Suckling treatments did not influence herbage intakes or daylight grazing times and nursing frequencies. Mean nursing intensities were 1·0 calves per single-suckled cow, compared with 1·8 calves (experiment 1) and 2·2 calves (experiment 2) per double-suckled cow. Double-suckled cows nursed significantly more ‘foreign’ calves than single-suckled cows. Total calf weight at weaning from double-suckled cows in experiments 1 and 2 was respectively 364·6 and 344·4 kg, which was 1·64 of the corresponding weights weaned by single-suckled cows (221·1 and 209·4 kg).

The correlation between polymorphisms in the IGF-1 gene and production traits in beef cattle is well known. The effect of insulin-like growth factor on the value of milk traits is not yet adequately understood. The aim of the study was to attempt to describe the effect of IGF-1/SnaBI substitution on selected milk performance parameters of the Black-and-White variety of Holstein-Friesian cows. Three genotypes were identified: CC, CT and TT. The results showed a correlation between IGF-1/SnaBI genotypes and milk yield (highest for CC homozygotes and lowest for CT heterozygotes). No relationship could be established between the genotype and the quality characteristics of milk.

Abstract This study was designed to analyse the effect of milking behaviour (temperament) of primiparous dairy cows on their milk and reproductive performance as well as survival to the second lactation. Milk performance, reproductive performance and culling data on 12028 Polish Holstein-Friesian primiparous dairy cows were acquired from the SYMLEK database. Using the methodology of the Polish Federation of Cattle Breeders and Dairy Farmers, the temperament of the cows was assessed as: 1 - calm, 2 - normal, 3 - excitable or aggressive. Primiparous cows from the analysed population were characterized by averagely normal temperament and optimal milking speed. Daily and lactation yield depended (P≤0.01) on the temperament of cows. Excitable (aggressive) cows had higher daily and lactation yield compared to normal and calm cows. The temperament trait was found to correlate (P≤0.01) also with functional traits such as milking speed, survival to the second lactation, and culling level. As milking speed increased, the proportion of cows with calm temperament decreased and that of excitable (aggressive) primiparous cows increased. As the temperament score increased, so did the proportion of primiparous cows sold for further breeding. Excitable (aggressive) primiparous cows had the lowest chance of survival to the second calving.

AbstractThis study compared the effect of feeding AmyPlus, a moist feed, as opposed to rolled wheat on the yield and composition of milk from dairy cows consuming grass silage based total mixed ration (TMR). Seventy-two Holstein-Friesian cows were distributed into AmyPlus (Treatment) and Wheat (Control) groups and loose housed on straw in an open shed. Each kg Wheat based concentrate contained 345g rolled wheat, 230g rapeseed meal, 115g sugarbeet pulp, 115g Molaferm 20, 115g soybean meal, 56g barley straw and 24g vitamin-minerals. In contrast, each kg AmyPlus based concentrate contained 501g AmyPlus (480g DM /kg), 105g rapeseed meal, 126g sugarbeet pulp, 126g Molaferm 20, 84g soybean meal, 41g barley straw and 17g vitamin-minerals. Here, AmyPlus was loaded directly into the mixer wagon to prepare fresh AmyPlus based TMR with a silage to concentrate ratio of 68:32. Each TMR was fed once daily to the corresponding group of cows also receiving 2kg of Distillers’ grains per cow in the parlour during milking. Daily milk yield and composition was recorded from November 1999 to February 2000. The overall daily Dry matter intake (DMI) of each TMR per cow remained uniform (20.19 vs 20.15 kg for Treatment and Control group respectively) across both groups. Daily milk yield and total cell counts per cow did not vary significantly (P>0.05) between groups during various months. While, milk fat and protein contents were greater in Treatment than Control group during each month, the differences were significant (P<0.05) only during November and December for fat and in January for protein. On average, the Treatment group tended to show a non-significant increase (P>0.05) in daily milk yield per cow by 0.144 kg than the Control group. The fat (46.2 vs 43.7) and protein (34.5 vs 33.5) contents in g /kg milk were also increased significantly (P<0.001) in Treatment compared with Control group. Total cell counts did not vary significantly (P>0.05) and remained within the acceptable limits. The cows consuming AmyPlus maintained their health as indicated by their intake, production, cell counts and general appearance. It would appear that AmyPlus can replace rolled wheat in TMR. However, it may be necessary to evaluate the storage, economic and environmental implications of using such moist co-products in silage based dairy rations.
