Abstract. The aim of the study was to compare the body weight and the parameters of reproductive performance in beef cows of various breeds following their import to Poland from 1995–1997. The analyses included cows of five beef breeds: Red Angus, Salers, Hereford, Limousin and Simmental. We have compared the body weights and calving intervals during the period from their arrival to Poland in 1995 until 2002, with subsequent calvings included in the analyses. Other aspects included calving difficulty, abortions, stillbirths and twin births. The analysis of the cows’ reproductive performance has revealed that the studied breeds differ in the calving interval. Best results were achieved by Simmental and Limousine cows, while Red Angus cows exhibited the poorest performance. The effect of subsequent calving on the calving interval was also confirmed. We have observed no differences among the mature cows with respect to the body weight and calving ease.

The ability of ruminants to regulate body temperature depends on the genotype. Dairy breeds are generally more sensitive to heat stress than beef breeds. Higher-producing animals are more susceptible to heat stress because they generate more metabolic heat. The objective of evaluating reproductive performance as a response of adaptability to the management and climatic conditions of the Humid Tropics. 78 animals were used (40 Brown Swiss, from Puno and 38 Mestizas from local origin) raised in humid tropic conditions. Parametric statistics are presented as analysis of measures of central tendency and dispersion, non-parametric statistics by frequency analysis, the χ2 test of independence was used to detect differences, α = 0.05. The categorized and continuous dependent variables were evaluated with Student's t test using SPSS Software v.23. The mean age at first estrus in Brown Swiss was 12.43 months, in mestizo cattle 18.68 months (P <0.05). Average age of first calving in Brown Swiss of 25.25 months versus mestizo cattle 28.34 months (P <0.05). Interval from calving to the first service in Brown Swiss was 99.29 days. Open days observed in Brown Swiss was 107.29 days. The pregnancy rate at the first service in Brown Swiss was 70.0% pregnancy at the first service and 30.0% at the second service, for the mestizo genotype it was 68.4% at the first service, 28.9 at the second and 2.6 at the third service (P> 0.05; X2 = 0.50; p = 0.47). It is concluded that bovine animals of the Brown Swiss genotype have a good reproductive performance in the Humid Tropic climate compared to the Mestizo genotype

AbstractThere is considerable concern about the consequences on fitness-related traits of using narrow breeding objectives for production traits. The aim of this study was to assess the potential consequences of selection for growth in French beef cattle breeds by estimating genetic correlations between growth, reproduction, calving and suckling traits of Charolais, Limousin and Blonde d’Aquitaine heifers. Data consisted of the records collected from 1985 to 2002 in progeny test stations that were used in the genetic evaluation of 284 Charolais, 125 Limousin and 118 Blonde d’Aquitaine AI sires. Seven traits were considered simultaneously in the analysis: weights at 18 months and after calving (for measuring heifer growth), sexual precocity and fertility (for measuring heifer reproductive performance), calving difficulty score and pelvic opening (for measuring calving ease) and milk yield (for measuring the suckling ability of the primiparous cow). REML (co)variance estimates were derived using linear multitrait sire models. Estimates of heritability were in the range of values given in the literature. They were very similar in the Charolais and Blonde d’Aquitaine breeds, and rather different for reproductive and suckling performance in the Limousin breed. Estimates were about 0·35 for heifer growth traits and about 0·15 for calving difficulty score in the three breeds. In the Charolais and Blonde d’Aquitaine breeds, estimates of heritability were 0·15 for sexual precocity and 0·05 for heifer fertility. These estimates were close to zero in the Limousin breed. Heritabilities of pelvic opening and milk yield were, respectively, 0·2 and 0·6 in the Limousin breed and around 0·3 in the other two breeds. Genetic correlations between traits concerning the same ability (as, for instance, weight at 18 months and weight at calving) were high and, in general, similar among breeds. Genetic correlations between heifer growth, reproductive traits, calving ease and suckling performance were nil or slightly favourable in the three breeds. Consequently, past selection mainly directed towards increasing growth seems not to have adversely affected the efficiency of female reproduction and the maternal abilities of French specialized beef cattle breeds.

This study aimed to elucidate the reproductive performance of purebred Holstein (HO) cows with their crosses with Fleckvieh (FV) and Brown Swiss (BS) cows under subtropical conditions. A total of 677 cows [487 HO, 104 HO × FV (HFV); 50% FV and 50% HO and 86 HO × BS (HB); 50% BS and 50% HO] were enrolled in this study. Pure HO cows had significantly greater service per conception (S/C; 3.69), days open (147.9 days), and calving interval (449.6 days), than the HFV (2.89, 116.7, and 407.4 days, respectively) and HB (3.07, 134.3, and 434.2 days, respectively) crossbred cows. At day 28, the conception percentage was significantly greater among HFV crossbred cows vs. pure HO cows [crude odds ratios (COR) = 2.16], but embryonic loss, abortion percentage, calving difficulty, and retained placenta percentage were similar (p &gt; 0.05) among pure HO cows and their crosses. HFV crossbreds had significantly lower incidence of endometritis (COR = 0.70, p = 0.035), mastitis (COR = 0.69, p = 0.015), and ketosis (COR = 0.53, p = 0.004) vs. other cows. HB and pure HO cows had a similar incidence of mastitis, lameness, and ketosis (COR = 0.76, 0.75, and 0.81; p = 0.223, 0.468, and 0.492, respectively). HFV crossbred cows had a lower risk of culling rate than HB crossbred cows. In summary, HFV cows demonstrated the best reproductive performance in terms of S/C, days open, calving interval, conception at 28 days, mastitis percentage, ketosis percentage, and endometritis.

Pelvic Measurement

Dystocia causes great financial losses: due to dystocia milk production is decreased and the probability of calf loss is increased. There are many factors that may cause dystocia. One of the factors –often investigated in beef cattle- is pelvic measurements. There have not been inner pelvic measurement comparisons done on dairy breeds in Hungary.After comparing the imported, primiparous cows, Jerseys turned out to have the smallest absolute inner pelvic measures. According to their age and weight, Brown Swiss cows had the largest pelvic dimensions. Ayrshire, Norwegian and Swedish Red, the three dairy breeds which share similar genetic background did not differ in most measures. Holsteins were closest to the apparent ideal 1:1 horizontal and vertical diameter ratio; however, this breed suffers the most from dystocia. Jerseys, despite having the smallest pelvic area are famous of their calving ease, perhaps not by coincidence. Although this dairy breed is the lightest, when the pelvic area was compared in ratio of body weight Jerseys were not smaller than the 130 and 114 kg heavier Norwegian and Swedish Red cows.
