The authors examined the body condition with relation to reproduction of Holstein-Friesian cows on three dairy farms in the South Plain region. During the examination they analyzed the data of 516 births of 494 Holstein-Friesian cows. They were trying to find correlation between the first service, the service period and the service rates. The examinations with regard to the correlations were different from the ones published in the professional literature. The body condition at the time of calving affected the interval from calving to the first service but not the conceptionrates or the service period. The examinations did not prove any correlations between body condition changes and reproduction.

This study examined the effect of the body condition of Polish Holstein-Friesian cows in the last month before calving and in the first week of lactation and of the rate of the body condition loss in the early lactation on basic fertility indicators. Body condition of a total 327 cows was evaluated using the 5-point BCS scale. Five fertility indices were included. The fertility indicators analysed depended less on the BCS of cows in the last month before calving and in the first week of lactation, and more on the size of body condition loss and its duration. Scores of over 3.5 both before parturition and at the start of lactation were associated with the longest service periods and with the lowest percentage of conceptions after one insemination procedure. The length of the days open and calving intervals and the number of services per conception increased as the length of the decline in BCS after parturition increased. The most favourable values for the fertility indicators analysed can be expected in cows whose BCS before parturition and at the start of lactation was 2.75-3.5. A smaller energy deficit with a shorter duration after parturition was also more favourable for these traits..

We carried out the examinations on a farm of 500 cows where We examined the body condition of the stock every month. We recorded the body condition data together with the milk production and calving data. We analysed the daily milk production as well as the body condition. During the examinations we sought an answer how the body condition and the production level change during the lactation period.

The relationships between body composition, live weight (LW) and subjective condition score (CS) were examined in an experiment in which 54, second to fourth parity, lactating autumn-calving Holstein-Friesian dairy cows were slaughtered at 0, 2, 5, 8, 11, 14, 19, 24 and 29 weeks post partum. Multiple regression analyses showed the weight of fat and the quantity of energy within the body were significantly correlated with both LW and CS. The weight of crude protein showed a linear correlation with LW. These results are discussed and compared with previously published investigations with non-lactating dairy cows.

In the last few decades, a new intensive milking stock has developed as a result of breed-converter crossing in Hungary. Additionally, the reproduction biology of the population was adversely affected by keeping and feeding technologies. Productive lifetime has shortened and the service period has lengthened. However, profitable milk production requires cows with longer productive lives and larger life-time productions. In our study, we made a comparison between production, culling causes, and type traits of culled Holstein Friesian cows after first calving and of cows with a minimum of eight lactations. We established that the first lactation production of cows with longer productive lives was more or less homogeneous. Disease of metabolism as well as digestive and respiratory problems, were the main causes of the culling of cows with short productive lives, and reproduction and udder problems as well as low production, were the main causes of the culling of cows with long productive lives. We found a significant difference in the distributions of strength, body depth, dairy form, croup width, rear leg side view, foot angle, fore udder attachment and teat placement between the two groups. Furthermore, we established that cows with lower stature, less strength, a somewhat deeper body, better dairy form, narrower croup width, smaller foot angle, looser fore udder attachment and some outside teat placement had longer productive lives.

Positive Effect

The objective of our research was to evaluate the effect of some factors on the embryonic mortality of Holstein-Friesian dairy cows in a herd. Monitoring was conducted in the course of three years (2006–2009) at a level of (9330–8970) kg/dairy cow per lactation. We monitored the reproduction parameters of 209 dairy cows (1st to 8th lactation). Ultrasonography was used to diagnose gravidity, and/or embryonic mortality, in each cow 6 times, at regular 4-day intervals between days 22 and 42 after insemination. We analysed the effect of 3 factors on embryonic mortality: age, body condition score and season of the year at the time of insemination. Embryonic mortality relative to the age of the female was significantly the lowest (20.69 %) in cows aged 42 to 47 months (3.5–3.9 years); high embryonic mortality (45.46 %) was recorded in the youngest females of 24 to 29 months of age (2.0–2.4 years). The results indicated that the body condition score of the cow at the time of insemination had a statistically significant (P > 0.01) effect on embryonic mortality (EM). Embryonic mortality was the lowest when the body condition of the cow was “ideal”, i.e. 5 points of the BCS (at the most 9 points). The season of the year when insemination was carried out had a positive effect on embryonic mortality.

The aim of the study was to analyse the relationship between the somatic cell counts in the milk (the udder health status indicator) and the cow’s fertility, taking the influence of the selected factors into account. The udder health status was determined based on the somatic cell count of the milk from 88 745 test-day records from 55 685 Polish Holstein-Friesian cows. The test-day measurements were made up to 30 days before the first insemination, during the period up to 180 days of the first and second lactation. Because the somatic cell count showed high variation and is not normally distributed, the data were transformed to the natural logarithm scale. Based on the results of the statistical analysis, it was shown that with the increase in the number of somatic cells in the milk, the calving intervals were extended by 11 days (P ≤ 0.01), the service period by around 4 days (P ≤ 0.05), the increase in the services per conception by 0.11 (P ≤ 0.01). There was a statistically significant correlation, weak on the Guilford scale, between the natural logarithm of the somatic cell count and the fertility of the cows: the calving interval – CI (r = 0.050**, P ≤ 0.01), service period – SP (r = 0.016**) end services per conception – SPC (r = 0.019**). Monitoring the number of somatic cells in the milk could contribute to improving the fertility of the cows in particular: in the second lactation in the double lactation (for the CI (r = 0.059**)); in herds with a production level of 7000–9000 kg of milk (for the CI (r = 0.055**), the SP (r = 0.022**) and the SPC (r = 0.024**)); the daily productivity of > 40 kg (for the CI (r = 0.052**), the SP (r = 0.033**) and the SPC (r = 0.029**)), the number of cows in the herd of > 200 (for the CI (r = 0.061**), the SP (r = 0.034**) and the SPC (r = 0.033**)), in the autumn season of the first insemination (for the CI (r = 0.072**), the SP (r = 0.027**) and the SPC (r = 0.031**)). The magnitude of these correlations varied within the classes of the factors such as the daily production level, the age of cows´ lactation number, the season of the first insemination, the herd production level, and the herd size. It appears that the somatic cell count results obtained from the periodic milk recording, considered as an indirect measure of the udder health and used when deciding on the mastitis treatment, could be a useful tool for controlling the fertility in the cows.

ABSTRACTBody condition score, assessed subjectively on the live animal, was related to the directly determined body composition of 73 mature, non-pregnant, non-lactating cows of Hereford × Friesian, Blue-Grey, Galloway, Luing and British Friesian genotypes. Relationships between condition score and chemically determined body fat were all very highly significant, and considered to be of value for predictive purposes. Differences between genotypes in the proportion of fat stored in the main depots of the body resulted in differences in the relationship between condition score and body fat. British Friesian cows had a higher proportion of their fat in the intra-abdominal depots and the lowest proportion of subcutaneous fat, resulting in their being fatter at any given condition score. Hereford × Friesian cows had the highest proportion of subcutaneous fat and were thus the least fat at any condition score. One unit change in condition score was associated with a change of 2242 (s.e. 103) MJ of body tissue energy in Hereford × Friesian, Blue-Grey, Galloway and Luing cows and 3478 (s.e. 392) MJ in British Friesian cows. These figures may be used to bring a greater degree of precision to the nutritional management of beef and dairy cows.
