Observation Results

The research was performed on 100 cows of Black and White Polish Holstein-Friesian breed. The studied cows were under a visual and tactile evaluation of body condition using a BCS (Body Condition Scoring) method performed on the day of parturition as well as 30th day of lactation. The observation results of the body condition changes during that period were juxtaposed with FPR. The value of that indicator was determined on the base of control milking performed on the 30th day of lactation. The aim of the research was defining the relationship between the value of FPR and the changes of cows’ body condition between the day of parturition and 30th day of lactation. The statistically significant differences (P < 0.05) of FPR value in dependence of the changes in cows’ body condition between the parturition day and 30th day of lactation were determined.

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 authors examined the data of 2767 trial milkings andthe months Body Condition Scores of 479 Holstein dairy cows. The condition loss was significant between the 30-60th days. The improvement of BCS begins only after the 120th day. The change in the milk protein and milk fat content were close after the condition changing. In each period of the lactation the closeness of the relationship among the condition, the milk quantity and the milk composition were different. In the aspect of the milk quantity the most significant difference was between the 2.5 and 4 BCS cows (6.68 kg) in the last period of the lactation.

Holstein Dairy Cows

The objective of this research was to evaluate the relationship between the course and the depth of negative energy balance (NEB) rated by changes of the body condition after calving and subsequent recovery of reproductive abilities of Holstein dairy cows treated by OVSYNCH. The body condition was evaluated by the BCS system one week before calving and subsequently at 30-day intervals for the period of 6 months of lactation. Recovery of ovarian functions was evaluated by the results of ultrasound examination of all the dairy cows’ ovaries in two controls after calving. The first one was performed on an average of 67 days after calving, and the second at a 60-day interval. The occurrence of individual findings - the presence of corpus luteum, ovarian cysts or ovaries without findings was evaluated as an effect of NEB on the recovery of the ovarian cycle of dairy cows and their subsequent possibility of conception. The suitable cows were treated by the OVSYNCH system after the 1st and 2nd ultrasound examination. Therefore, the insemination interval was calculated and in the case of dairy cows, pregnancy detection, also the number of services per conception and the length of open days. Twice performed hormonal treatment of 73.6% of the animals delayed the period by 50.2 days. In all, 202 dairy cows calved in the period from 29th July 2011 to 7th February 2012 were included in this observation. Significant effects of the body condition change on the ovarian activity as documented by sonographic examination and reproductive indicators appeared primarily in the second month of lactation. The best reproductive indicators were found in cows with the lowest body condition change, thus with a small decline or even increase of body condition score (−0.0 to +0.75 points, P < 0.05). On the contrary, the worst level of indicators of recovery of the reproduction functions were documented in the dairy cows with the most marked decline of BCS (P < 0.05).

Peak Lactation

A significant factor in improving the performance of dairy cows is their physiological ability to correct a negative energy balance (NEB). This study, using Simmental (SIM) and Holstein-Friesian (HF) cows, aimed to assess changes in NEB (non-esterified fatty acid; body condition score; and C16:0, C18:0, and C18:1) and its effect on the metabolic efficiency of the liver (β-hydroxybutyrate and urea). The effects of NEB on daily yield, production at peak lactation and its duration, and changes in selected milk components were assessed during complete lactation. Up to peak lactation, the loss of the body condition score was similar in both breeds. Subsequently, SIM cows more efficiently restored their BCS. HF cows reached peak lactation faster and with a higher milk yield, but they were less able to correct NEB. During lactation, their non-esterified fatty acid, β-hydroxybutyrate, C16:0, C18:0, C18:1, and urea levels were persistently higher, which may indicate less efficient liver function during NEB. The dynamics of NEB were linked to levels of leptin, which has anorectic effects. Its content was usually higher in HF cows and during intensive lactogenesis. An effective response to NEB may be exploited to improve the production and nutritional properties of milk. In the long term, it may extend dairy cows’ productive life and increase lifetime yield.

Body Condition Scoring

The aim of the current study was to evaluate the relation of automatically determined body condition score (BCS) and inline biomarkers such as β-hydroxybutyrate (BHB), milk yield (MY), lactate dehydrogenase (LDH), and progesterone (mP4) with the pregnancy success of cows. The cows (n = 281) had 2.1 ± 0.1. lactations on average, were 151.6 ± 0.06 days postpartum, and were once tested with “Easy scan” ultrasound (IMV imaging, Scotland) at 30–35 d post-insemination. According to their reproductive status, cows were grouped into two groups: non-pregnant (n = 194 or 69.0% of cows) and pregnant (n = 87 or 31.0% of cows). Data concerning their BCS, mP4, MY, BHB, and LDH were collected each day from the day of insemination for 7 days. The BCS was collected with body condition score camera (DeLaval Inc., Tumba, Sweden); mP4, MY, BHB, and LDH were collected with the fully automated real-time analyzer Herd Navigator™ (Lattec I/S, Hillerød, Denmark) in combination with a DeLaval milking robot (DeLaval Inc., Tumba, Sweden). Of all the biomarkers, three differences between groups were significant. The body condition score (BCS) of the pregnant cows was higher (+0.49 score), the milk yield (MY) was lower (−4.36 kg), and milk progesterone in pregnant cows was (+6.11 ng/mL) higher compared to the group of non-pregnant cows (p < 0.001). The pregnancy status of the cows was associated with their BCS assessment (p < 0.001). We estimated that cows with BCS > 3.2 were 22 times more likely to have reproductive success than cows with BCS ≤ 3.2.

The antioxidant drug "E-selenium" was used to reduce the processes of LPO in the body of fresh cows. Two groups were formed from the analogous cows of the black-and-white breed: The Control was intact, Experienced received the antioxidant drug injection at a dose of 10 ml at the rate of 1 ml per 50 kg of live weight per head for 4 months of lactation from the second. The diets of animals of all groups were the same, balanced in nutrients and met the standards of the RAAS. The duration of the experiment was 150 days. During the period from the 3rd to the 5th month of lactation, there was a positive dynamic in increasing the number of fat globules in the milk of cows of the Experimental group. By the end of the 4th month, it was higher than the Control by 8.9 %. This confirms the active effect of the drug "E-selenium", which contributes to a positive dynamic in increasing the size of fat globules. Non-enzymatic antioxidant tocopherol is an active element of the anti-oxidative system. Selenium stimu-lates the body's own antioxidant system. In both experimental groups, the relationship between the concentration of peroxidation products and the quantitative composition of fat globules and their size was established. In the milk of cows of the Experimental group, the oxidation processes were inhibited by neutralizing the products (POL), increasing the number of large fat globules and the total fat content in the milk.

Abstract The aim of the study was to find the relationship between some postpartum disorders and pregnancy losses (PL), and the influence of PL on further fertility of Holstein-Friesian dairy cows. The 1,056 pregnancies and 906 calving intervals (CI) of 378 cows during the nine-year observation period were analysed. The average milk yield during this period increased from 7,500 to 10,500 kg/305 d of lactation. All cows up to 4 weeks after calving were gynecologically examined and cases of genital tract disorders were recorded and treated. Artificial inseminations (AI) were made using commercial frozen/thawed semen. In cows with silent ovulation, oestrus was induced by injection of PGF2α or programmes using PGF2α and GnRH, or hCG were applied. Pregnancy was diagnosed with the use of ultrasonography or foetal membrane slip only from 30 and 42 d after service, respectively, and re-diagnosed between 70 and 90 d after AI. The cases of „early foetal loss” up to 90 d and „mid-to-late PL” between 91 and 260 d after AI were recorded. Endometritis was noted in 31.8%, ovarian cysts in 8.5%, whereas ovarian inactivity in 4.6% of cows. Early PL was observed in 5.2%, whereas mid-to-late PL in 6.8% of cows (total 12%). From all analysed factors, the influence of delayed or periodical lack of ovarian activity was significant with regard to early PL (P=0.029). The probability of early PL increased when besides the diagnosis of ovarian inactivity, AI was made following an induced oestrus (P=0.003). CI for cows, which did not lost pregnancy amounted 442.9 d. The early, mid-to-late and multiple PL extended the CI to 579.6, 661.1 and 657.7 d, respectively (P<0.05). Concurrently, CI for cows with “early foetal loss” was significantly shorter comparing to cows with “mid-to-late foetal loss” (579.6 d vs.661.1 d; P<0.05). On average 2.6 inseminations for one pregnancy were needed, and each PL increased the AI index. Significant differences were stated after early and multiple foetal losses (5.2 and 5.1 vs. 2.6; P<0.05).
