Rumination behavior in cattle is important for health and reproduction management of herd. The aim of presented paper was to evaluate change in rumination behavior in dairy cattle after changing total mixed ration (TMR) composition. Twenty-eight multiparous Red Holstein dairy cows were observed during rumination in first month after calving and in fourth month after calving. Cows were fed different total mixed ratio at beginning of lactation in first month after calving (TMR1) and in mid of lactation period in fourth month after calving (TMR2). TMR2 has higher content of roughage. Length of the single rumination period and number of jaw movements during rumination one bolus were recorded. Frequency of jaw movement per minute was calculated from recorded rumination characteristics. Rumination of one bolus TMR2 was longer (TMR1 = 53.97 ±8.241 sec, TMR2 = 57.57 ±6.290 sec) and cow perform more jaw movements (TMR1 = 61.0 ±10.674, TMR2 = 65.99 ±9.682) than ruminating bolus TMR1. Difference in duration of rumination one bolus as well as number of jaw movement was significant (P < 0.001). Frequency of jaw movement was not significantly affected (P > 0.05) and seem to be intra-individual stable. Rumination evaluated by correlation of rumination characteristics for TMR1 and TMR2 was intra-individual stable despite of changes in times of jaw movement and duration of one bolus rumination.

Reproduction and milk production are the principal factors that are influencing dairy farm profitability. The dairy industry in Iran has changed dramatically in the last decade. The shift toward more productive cows and larger herds in Iran is associated with a decrease reproductive efficiency (Heravi Moussavi et al., 2004). Increased knowledge about the principal causes of reduced fertility is essential. The root cause of the declining fertility is probably a combination of a variety of physiological and management factors that have an additive effect on reproductive efficiency. Dairy cattle are inseminated and pregnancy is established while dairy cows are lactating. Based on the analyses of large datasets, there is clearly an antagonistic relationship between milk production and reproduction in dairy cattle (Lucy, 2001). It was shown that the hazard ratio for cumulative first 60-day milk yield and conception in high producer cows was 8 percent less than the others and also high milk yield was a risk factor for several reproductive disorders (Grohn and Rajala-Schultz, 2000). The objective of this study was to evaluate the effect of first 60-day cumulative milk yield on days open in Iranian Holstein dairy cows.

The aim of the study was the influence of claw disorders on production traits in dairy cattle. Observed were claw traits as claw angle, claw length, heel index, claw height, claw diagonal and claw width. Right hind claw after functional trimming was evaluated. Occurrence of claw disorders like interdigital dermatitis and heel erosion (IDHE), digital dermatitis (DD) and sole ulcer (SV) as well as the progress of disease were observed. Basic summary and variation statistics was performed by the SAS software. Two herds were included in the study. Holstein dairy cows (n=101) produced 11 875 kg of milk, 468 kg (3.94%) of fat and 396 kg (3.34%) of proteins. Holstein cows were affected with IDHE in 22 cases, with DD in 6 cases and with sole ulcer in 10 cases. Slovak Simmental dairy cows (n=101) produced 5834 kg of milk, 258 kg (4.44%) of fat and 209 kg (3.59%) of proteins. Slovak Simmental cows were affected with IDHE in 8 cases, with DD in 5 cases and with sole ulcer in 19 cases. Observed was that claw disorders caused deviations of milk production.

This study aimed to monitor the effect of including rumen-protected L-carnitine (Carneon 20 Rumin-Pro, Kaesler Nutrition GmbH, Cuxhaven, Germany) in the transition diet on the productive and metabolic responses of multiparous high-producing Holstein dairy cows. Thirty-two multiparous cows were allocated in a completely randomized design to receive the same diet plus 60 g fat prill containing 85% palmitic acid (control, n = 16) or 100 g rumen-protected L-carnitine (RLC, n = 16); at 28 days before expected calving until 28 days in milk (DIM). Fat prill was included in the control diet to balance the palmitic acid content of both experimental diets. Milk production over the 28 DIM for the control and RLC groups was 46.5 and 47.7 kg, respectively. Milk fat content tended to increase upon rumen-protected L-carnitine inclusion (p = 0.1). Cows fed rumen-protected L-carnitine had higher fat- and energy-corrected milk compared with the control group. Pre- and post-partum administration of L-carnitine decreased both high- and low-density lipoprotein concentrations in peripheral blood of post-partum cows. The results of this study indicated that the concentration of triglycerides and beta-hydroxybutyrate was not significantly different between the groups, whereas the blood non-esterified fatty acid concentration was markedly decreased in cows supplemented with L-carnitine. Animals in the RLC group had a significant (p &lt; 0.05) lower blood haptoglobin concentration at 7 and 14 DIM than the control. Animals in the RLC group had a lower concentration of blood enzymes than those of the control group. The mRNA abundance of Toll-like receptors 4, cluster of differentiation 14, and myeloid differential protein 2 did not significantly change upon the supplementation of L-carnitine in the transition diet. In summary, the dietary inclusion of RLC improved dairy cow's performance during the early lactation period. Greater production, at least in part, is driven by improved energy utilization efficiency and enhanced metabolic status in animals during the periparturient period.

The objective of this study was to evaluate the welfare status of high-producing Holstein dairy cows on commercial Croatian farms. Lying behavior data was collected from 278 dairy cows across four farms with varying milking parlors and housing systems in eastern Croatia for at least 3 days. Data loggers recording at 1-min intervals recorded behaviors: lying time (min/d), lying bout duration (min/bout), lying bouts (n/d) and laterality of lying. Acceleration data was summarized into lying behaviors for each individual cow. Health scores (udder cleanliness, locomotion, and hock injuries) were also assessed. The univariate procedure was used to generate mean lying behaviors and health scores by farm with a 95% CI. Mean lying time per farm ranged from 11.7 ? 2.7 to 10.4 ? 2.7 h/d. Prevalence of lame cows ranged from 28% to 50%. Heavily soiled udders ranged from 2% to 12%. Prevalence of left hocks with minor to major swelling ranged from 50% to 100%; prevalence of right hocks with minor to major swelling ranged from 45% to 100%. In conclusion, all farms assessed have opportunities to improve overall welfare through increasing udder cleanliness and reducing hock injuries.

This study aims to determine the correlations between the test-day milk yield (TDMY) and the fat and protein content as well as the fat and protein yields in Holstein dairy cows and to investigate the effects of lactation period and sampling season on these parameters. The study material consists of 1.380 records of a total of 151 head of Holstein dairy cows raised on a private farm in Samsun province. In the study, the mean TDMY, fat content, protein content, fat yield and protein yield were recorded as 20.6±5.10 kg, 3.97±0.734%, 3.23±0.276%, 0.81±0.210 kg and 0.66±0.160 kg, respectively. The effects of lactation period and sampling season on the TDMY, fat content, protein content, fat yield and protein yield were found statistically significant (Pis less than 0.01). Statistically significant negative correlations were determined between the TDMY and the fat and protein content, but positive and statistically significant (Pis less than 0.01) correlations between the TDMY and the fat and protein yields. In conclusion, it might be stated that the effects of lactation period and sampling season should also be taken into account to improve milk yield and milk components.

This study was conducted to examine the influences of replacing soybean meal (SBM) with fermented soybean meal (FSBM) in the diet of lactating Holstein cattle on rumen fermentation and ruminal bacterial microbiome. Twenty-four lactating Chinese Holstein dairy cattle were assigned to each of the two treatments in a completely randomized design: the SBM group [the basal total mixed ration (TMR) diet containing 5.77% SBM] and the FSBM group (the experimental TMR diet containing 5.55% FSBM). This trial lasted for 54 days (14 days for adjustment and 40 days for data and sample collection), and samples of rumen liquid were collected on 34 d and 54 d, respectively. The results showed that replacing SBM with FSBM significantly increased the molar percentages of propionate (P &lt; 0.01) and valerate (P &lt; 0.05), but reduced the total volatile fatty acid (TVFA) concentration (P &lt; 0.05), butyrate molar proportion (P &lt; 0.05), and the acetate to propionate ratio (P &lt; 0.01). The copy numbers of total bacteria (P &lt; 0.05), Fibrobacter succinogenes (P &lt; 0.01), Selenomonas ruminantium (P &lt; 0.01), and Prevotella spp. (P &lt; 0.05) in the FSBM group were greater, while the density of Prevotella ruminicola (P &lt; 0.05) was lower than those in the SBM treatment. Additionally, Succiniclasticum ruminis and Saccharofermentans acetigenes were significantly enriched (P &lt; 0.05) in the rumen fluid of FSBM-fed cows, despite the fact that there was no remarkable difference in the Alpha diversity indexes, structure and KEGG pathway abundances of the bacterial community across the two treatments. It could hence be concluded that the substitution of FSBM for SBM modulated rumen fermentation and rumen bacterial microbiota in lactating Holstein dairy cows. Further research is required to elucidate the relevant mechanisms of FSBM, and provide more insights into the application of FSBM in dairy cattle.

(Creating milk production correction factors of dairy cattle)ABSTRACT. The aim of the research was to obtain the correction factors of non-genetic effects that have influence on milk production of dairy cows. The research used a survey method on milk records of dairy cows kept in Dairy Cattle Breeding Center (BBPTU) of Baturraden. The data taken was only those relevant with the research objective. The data examined were as many as 324 production records of 108 dairy cows which had completed first three lactation, originated from 36 sires. Non-genetic factors studied were season, lactation period, number of days in milk of a lactation and age at birth. The effects of non-genetic factors were estimated through Stepwise multiple regression method. Effect of the number of days in milk of a lactation was highly significant (P ≤ 0.01), age at birth was significant (P ≤ 0.05), and season and the lactation period were not significant (P0.05) on milk production of dairy cows. Variables that have effect on milk production were then assigned the correction factors. Correction factors were derived from the least square mean (LSM) of the actual milk production. The correction factors were obtained by comparing the base LSM to the created LSM values on particular classes. The corrected milk production was obtained by multiplying the corresponding correction factor obtained with the actual milk production. Based on the study, the local correction factors lower the milk production variability of dairy cows.

Paratuberculosis is an economically important disease in dairy cows and requires continuous surveillance. The study aimed to investigate the seroprevalence of bovine paratuberculosis (Johne’s disease) in one of dairy farm in Egypt. A total of 964 dairy cattle were blood sampled and examined with an ELISA method. One-hundred fifty-five (16.1%) samples reacted positively. The results revealed that age was significantly associated with the prevalence of paratuberculosis in dairy cattle, particularly in animals over 6 years of age. Furthermore, the lactation period, milk yield and pregnancy had non-significant effect on appearance of paratuberculosis in cattle.
