Metabolic hormones [insulin, leptin, insulin-like growth factor-I (IGF-I), thyroxine (T4) and triiodothyronine (T3)], progesterone (P4) and beta-hydroxybutyrate (BHB) serum concentrations were evaluated and their effect on the superovulation results of donor cows was investigated in a semi-arid environment. Body weight, body condition score (BCS) and lactation stage were also included in the analysis. Twenty-three Holstein-Friesian cows were superovulated with 600 IU FSHp following the routine procedure and flushed on day 7 in a Multiple Ovulation and Embryo Transfer Centre in the semi-arid area of Brazil. The corpora lutea (CL) were counted and blood samples were collected for assays. All of the hormones investigated and BHB serum concentrations were within the physiological ranges. There was a positive correlation between hormones, except between BHB and all the others. The leptin level was influenced by feeding status, as indicated by the BCS. Insulin, T4, T3 and BHB levels were affected by milking status. Dry cows had higher levels of all hormones except BHB. An optimum level of leptin resulted in the highest number of CL, while the linear increase of P4, T4 and IGF significantly increased the number of CL.

Changes of progesterone (P4) profiles and oestrous cycle were investigated up to 70 days in 20 superovulated Holstein-Friesian cows in a dry tropical environment (Brazil). Superovulated cows showed no significant differences in relation to P4 level at the time of embryo recovery (39.0 ± 27.1 nmol/L, P = 0.536), first and second (12.0 ± 6.0 and 10.7 ± 2.2 nmol/L, P = 0.543) cycle. There was a close correlation between serum P4 concentration and the number of corpora lutea (CL; 13.3 ± 9.5) at the recovery (P < 0.0001). After the embryo collection, cows returned to cycle in different ways: (i) group of donors returning to cycle after 2.2 ± 0.8 days, (ii) group with a delay of 11.0 ± 1.9 days; and (iii) animals having a long (28.8 ± 2.2 days) acyclic period, which is significant (P < 0.001). The remaining animals (30%) showed cystic ovarian malformations. P4 level at the time of embryo recovery does not influence the oestrous cycle changes. The results suggest that Holstein-Friesian donor cows may suffer from cystic ovarian degeneration and may have a long acyclic period after superovulatory treatment in a tropical climate.

Abstract The objective of this study was to estimate the influence of lactation number, month of milk sampling, lactation stage and herd size on the freezing point of milk of Polish Holstein‑Friesian cows. Data comprised 4,719,787 milk samples from the first seven lactations of 752,770 Polish Holstein- Friesian cows. Milk freezing point (MFP), milk yield, and fat and protein content were analyzed. The mean MFP of milk samples (-0.5326°C) as well as more than 92% of all milk samples did not exceed the quality limit for the freezing point of cows′ raw milk, which, following Polish standards, was taken to be -0.52°C. The freezing point of milk samples, milk yield, fat and protein content were highly significantly affected by all examined factors: month of sampling, successive lactations, stage of lactation, and herd size. MFP was lowest in milk samples taken from January to March, and highest in samples from November to December. MFP increased with lactation number. Mean MFP decreased with time within lactation, except the first stage (5-35 days in milk). Generally, MFP was highest in small herds (up to 9 cows) and lowest in large herds (more than 150 cows).

The aim of this study is to examine the interrelationships and importance of biochemical and endocrine blood parameters in the assessment of beta-hydroxybutyrate (BHB) values in healthy and ketotic cows using multiparameter statistics. The experiment included 45 Holstein Friesian cows (22 healthy and 23 with ketosis). The criterion used for detecting ketosis was the value of BHB ˃1.2 mmol/L. Based on laboratory indicators, cows were precisely classified into two large clusters: a cluster of healthy cows and a cluster of cows suffering from ketosis with minimal mixing of individual cows between clusters. Metabolic parameters were divided into two large clusters: parameters whose values increased in ketosis and decreased in healthy animals and parameters whose values decreased in ketosis and increased in healthy individuals. In ketotic cows there was a higher expression of non-esterified fatty acids, total bilirubin, aspartate aminotransferase, insulin and growth hormone, and a lower expression of glucose, albumin, triglycerides, cholesterol and total lipids compared to the healthy group. In 3 cows with ketosis, greater metabolic similarity with healthy cows was found, because of the absence of pronounced changes in the concentration of hormones and glucose. Thyroxine and triiodothyronine showed either increased or decreased expression in ketotic cows. In cows with lower values of these hormones, there were more pronounced metabolic changes characteristic of ketosis. For the development of metabolic adaptations to ketosis, in addition to hyperketonemia, there must be endocrine changes and changes in glycemia.

AbstractThe effect of first lactation yield and herd production level on longevity was studied using data from the SYMLEK database on 12045 Polish Holstein-Friesian cows in 1371 farms from the active population in Pomerania and Kujawy. The cows first calved in 2008 and were used or disposed from the herds by the end of 2015. FREQ, GLM and CORR procedures from the SAS package were used in the statistical calculations. The optimum level of first lactation milk from the viewpoint of longevity varies according to herd production level, which serves as a measure of the quality of rearing conditions. If the living conditions are not adapted to the high milk production of first calvers, there is a possibility that their productive life will be shortened and number of calvings decreased. The percentage of voluntary culling decisions by the breeder, which included the sale for further breeding, low milk yield and old age, averaged 9% and decreased with increasing herd production level from 16% to around 6%. The main reason for culling was infertility (around 40% on average). Culling due to infertility was particularly common among the cows which produced more than 11000 kg milk as first calvers.

This study investigated the effect of diets negative in dietary cation–anion difference (DCAD) or restricted in Ca fed prepartum to dairy cows for three weeks on colostrum yield and composition, and the health and growth performance of their calves. Thirty-six pregnant non-lactating Holstein-Friesian cows were randomly assigned to three isoenergetic diets: (1) low Ca: 0.24% Ca, DCAD: +86 mEq/kg; (2) high Ca: 1.23% Ca, DCAD: +95 mEq/kg; and (3) low DCAD: 1.28% Ca, DCAD: −115 mEq/kg (all dry matter (DM) basis). While colostrum quality was not affected, low Ca supply prepartum tended to increase the colostrum yield compared to high Ca (low Ca = 8.81 vs. high Ca = 5.39 kg). However, calves from cows fed low DCAD showed higher serum concentrations of K, lower body weight (BW), starter feed intake and average daily weight gain before weaning compared to low Ca and high Ca calves (53.12 vs. 57.68 and 57.32 kg) but BW was similar postweaning (d 70). In addition, calves from dams fed low DCAD were more likely to develop diarrhea and had increased number of days with abnormal fecal scores. Consequently, calves from low DCAD dams had to be treated more frequently.

Two experiments were undertaken to determine whether there was a relationship between embryo survival and the blood serum concentration of thyroxine (T4) triiodothyronine (T3), growth hormone (GH), insulin (INS), glucose (Glc) and progesterone (P4), as influenced by diet intake. In exp. 1, serum concentrations of T4, T3, INS, Glc and P4 were measured in samples collected at 0.0 (preprandial), 0.33, 0.67, 1.0, 1.5, 2.0, 3.0, 5.0 and 7.0 h (postprandial) on days 7, 11, 15 and 25 of gestation. In exp. 2, 16 control (C) gilts gained 0.49 ± 0.04 kg d−1, while 19 restricted (R) gilts were fed at the same level, except from days 1 to 10 after mating, when diet intake was restricted to 50% of the C gilts. The R gilts from days 0–10 and days 10–20 gained −0.01 ± 0.05 kg d−1 and 0.59 ± 0.06 kg d−1, respectively. Gilts were bled at 5 h postprandial on days 1, 4, 7, 9, 11, 13, 15, 20 and 25, and eight samples were collected on days 7, 11, 15 and 25, from 0–5 h postprandial. Embryo survival was expressed as a percentage of the number of corpora lutea. In exp. 1, T4 and T3 concentrations on day 7 were greater than those on days 11 and 15 (and day 25 for T4). The INS profile was not affected by day of gestation, while Glc profiles differed for days 7 and 25. In exp. 2, a day-of-gestation effect was observed for T4 and T3, with elevated levels on days 1 and 4. Postprandially, T4 increased by 20 min and remained constant, while T3 peaked at 1.5 h; GH showed no change; and INS peaked at 1 h. The INS peak for R gilts was lower on day 11, and GH concentration was lower for R gilts on days 7, 11 and 15. Correlations were only consistently significant between T4 and T3, and between INS and Glc, and for days 1–11 for progesterone with T4 and T3. Correlations of hormone concentrations with embryo survival were generally not significant. These results show that T4 and T3, GH and INS responded differently to the day of early gestation and to diet intake. There were no changes in hormone concentration that could be associated with embryo survival. Key words: Pregnant gilts, diet intake, metabolic hormones
