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 objective of the present study was to investigate the effects of somatic cell count (SCC) and body condition score (BCS) on reproduction and milk composition characteristics in Czech Holstein cows. A total of 275 records of chosen cows was evaluated by milk composition, SCC, BCS and fertility traits. Infrared spectroscopic method was used for SCC test and an automatic device was used for milk composition analysis. Before statistical test, SCC data were transformed to log10 for normality and homogeneity of variances. BCS was performed using a 1-5 point scale and days from calving to first insemination (ICF), number of inseminations per conceptions (NIC) and days open (DO) were assessed as fertility parameters. To evaluate days in milk (DIM) on SCC and BCS, two groups were designed (group 1: cows in 1-69th day DIM and group 2: cows in 70-119th DIM). For testing BCS on chosen traits; cows with 2.50 £ BCS and cows with BCS ³ 2.75 were tested in two groups. All statistical work was applied by SPSS 17.0 at the 0.05 significance level. It was found that SCC elevated with high parities and cows with lower BCS had lower milk protein percentage. Cows with lower BCS had lower reproduction traits than those with higher BCS. Correlation coefficient between two markers was estimated as r= -0.181. Calculated means for the parameters could be assessed in reasonable thresholds. The study revealed that SCC played a marked role on protein percentage of milk, and BCS affected important reproductive characteristics of Czech Holstein cows.

The objective of this study was to assess various risk factors affecting fetal losses in high-yielding Holstein cows in a hot environment. In a retrospective observational study, 14,384 records from Holstein cows from a large highly technified dairy herd in northern Mexico were used. Logistic multivariate multiple-group response model indicated that fetal losses between 43 and 260 days of pregnancy were 23.8%. Dry periods >60 d were associated (p<0.05) with 0.8 (confidence interval CI=0.8–0.9) times lower incidence of fetal losses compared to cows with dry periods <60 d. Cows with body condition score (BCS) >3 at calving and 15 days postpartum had about half the risk of suffering fetal losses than cows with BCS <3.0. Cows with peak milk yield >38 kg were 5.5 times more likely to have a fetal loss than cows with peak milk yield <38 kg (36.9 vs. 9.6%; p<0.01). The risk of fetal loss increased with 305-d milk yield >9,000 kg (OR=2.1) compared with cows with milk yield <9,000 kg. Retained placenta was (p<0.05) associated with 1.2 (CI=1.1–1.4) times higher fetal losses than cows without this reproductive disorder. Cows suffering premature parturition had 1.2 (CI=1.0–1.4) greater (p<0.05) risk of suffering fetal losses than cows with normal parturition. Cows with twin pregnancies had significantly increased chances of losing their fetuses than cows with a single fetus (31.1 vs. 15.9 p<0.01). A bimodal distribution of fetal losses was observed with peaks around 50 and 220 days of pregnancy. It was concluded that in this particular hot environment fetal losses were associated with high milk yield, low body energy reserves at calving, reduced dry periods, occurrence of retained placenta, twin pregnancies and premature calving.
