The study was carried out on 27 healthy primiparous Holstein heifers (620 ± 50 kg) kept in a commercial dairy herd. The animals were divided into two groups taking into account the body condition score (BCS) index: BCS < 3.5, n = 12; BCS > 3.5 n = 15. The study period started one month before calving (BC), and ran until one month after calving (AC). Venous blood samples were collected 1 month and 1 week BC, and 1 week and 1 month AC. This study had two objectives: (i) to assess whether a higher or lower BCS affected total milk production and its quality; (ii) to assess changes in the internal fluid (venous pH; partial pressure of CO2, ppCO2; bicarbonate; total CO2, TCO2; base excess, BE; electrolytes Na+, K+, Cl−; and anion gap, AG) that occur during this phase depending on the BCS. We can conclude that the BCS at calving does not affect the productive status during lactation, both in terms of the quantity and quality of milk produced. The excess of crude protein (CP) added through the ration in the lactation phase can trigger a tendency to an alkalotic state, in this case compensated by respiratory buffering mechanisms, as reflected by the TCO2. The changes in electrolytes are a reflection of the movement of free water for milk production, where a balance between measurable anions and cations is observed.

Abstract The objective of this study was to evaluate the milk production, body weight, and body condition score (BCS) of ewes fed with different energy levels. Seventy-one ewes were used and distributed in three treatments according to the metabolizable energy (ME, Mcal/kg) levels in the diet: CTL = according to the NRC (2007) recommendation for each stage (gestation and lactation); PLUS = CTL plus 10% of ME per kilogram of dry matter; LESS = CTL less 10% ME per kilogram of dry matter. Body weight and body condition score were evaluated a week before the expected date of parturition, a week after giving birth, and at weaning (60 days). Dairy production was evaluated at 20, 30, 40, 50 and 60 days after giving birth by the indirect method of the two weighing. The experimental design was analyzed as randomized complete blocks. There were no differences on milk production during almost all the lactation curve. Only on day 50 (P = 0.051), CTL was still at peak, while LESS and PLUS had already decreased their production. However, at 60 days, all treatments were already with low production, justifying weaning in this period. Results of weight and BCS showed a significant difference in all periods evaluates. Ewes in the PLUS diet had greater BW and BCS. The BCS before giving birth is expected to be over 3.5 and treatment LESS was the only one that did not achieve this score (2.66, 3.37, 3.83 for LESS, CTL, and PLUS, respectively). At weaning, ewes fed PLUS and CTL had BCS of 3.51 and 2.92, respectively, but treatment LESS had only 1.82. That is prejudicial for the next mating seasonal and this animal. We concluded that LESS diet interfered with the body reserves of sheep.

Condition Score

The body condition score (BCS) at calving has been postulated as the main factor in the interaction of nutrition and reproduction in beef-cow ecosystems. The objective of the present study was to analyse the effect of BCS at calving on endocrine and metabolic profiles during the transition period in primiparous Hereford cows (n = 56) grazing native grassland. Cow BCS was registered and plasma insulin, insulin-like growth factor-I (IGF-I) and metabolites (concentrations of urea, albumin, cholesterol, total protein, non-esterified fatty acids (NEFA)) were determined in plasma from –30 to +45 days postpartum (DPP). The effect of BCS at calving (low ≤3.5 and moderate ≥4; 1–8 visual scale) on BCS evolution and hormone and metabolite concentrations were analysed using a time repeated-measures analysis. Cow BCS, NEFA, urea and IGF-I profiles were affected (P < 0.05) by the BCS at calving and DPP interaction, while insulin tended (P = 0.06) to be affected only by BCS at calving. The low-BCS cows presented a smaller loss of BCS during the prepartum than did moderate-BCS cows, and a delayed BCS recovery during the postpartum. The increase in plasma NEFA was greater (P < 0.05) and started earlier during the prepartum period in the low-BCS cows. Protein concentrations increased during prepartum to +30 DPP, while albumin and urea concentrations were maintained until calving and decreased during the postpartum. Urea concentrations were greater (P < 0.05) during prepartum in low-BCS cows. Concentrations of IGF-I and insulin were greater (P < 0.05) in moderate- than low-BCS cows during prepartum, but did not differ between the groups after calving. No effects were observed in calf weight or milk production at +45 DPP. The association between BCS during prepartum and at calving with the endocrine and metabolic profiles (positive: insulin, IGF-I; negative: NEFA and urea) reflected a better nutritional status and plasticity to negative energy balance on moderate cows. This different endocrine milieu did not affect calf weight and/or milk production. In conclusion, the BCS at calving affected the metabolic and endocrine profile during the transition period of primiparous beef cows grazing native grassland.

The aim of this research was to observe the Body Condition Score (BCS) and milk production of Friesian Holstein (FH) dairy cattles. 144 of dairy cattles divided into 3 groups based on BCS 1-9 scale. The results showed that Y = 6.62 + 5.54X - 5.78X2. Coefficient of determination (R2) of 20.6 this mean any increase in milk production by 20.6% is affected by BCS. It can be concluded that there is a correlation between Body Condition Score (BCS) and milk production. The higher BCS (BCS 7-8) the lower milk production, while in ideal BCS production (5-6) the production of milk is optimize.

Body Condition Scores

The authors carried out an examination on two Saanen goat farms during four months from May to August 2008. The body condition score and milk production of the goats were measured. In data processing analysis of variance was used to compare the data of the studied farms. They tried to find the answer for the question how the body condition scores and milk production change in each month. The changes observed in each farm were examined separately then they compared the values of the two farms.. On one of the farms the nutrition was proper therefore with an ideal, intermediate body condition (average 2.73) the goats produced a good amount of milk (2.5 milk-kg/mother/day). On the other farm the nutrition was not proper, therefore the body condition of the goats was weak (average 1.88). Their milk production decreased significantly from month to month (average 2.35 milk-kg/mother/day). The authors could conclude considering both farms that the more milk the goats produced, the lower their body condition score became. The two parameters showed negative correlation.

The objective of the investigations presented in this work was to establish the effects of a glycerol-based energy supplement in the diet of high-yield dairy cows on their body condition and production results during the early stage of lactation. Forty-seven cows were selected before calving, and they were divided into two groups: controls (n=26) and experimental (n=21). Cows of the experimental group were administered the preparation 'Energy Top' (Biochem GMBH, Germany), in a quantity of 250 ml daily during the final two weeks of the dry period and until the 60th day of lactation. The body condition score (BCS) of all cows was determined 10 days before calving, and on days 15 and 60 after calving. Blood samples were taken 10 days before and 15 days after calving, and concentrations of glucose and beta hydroxi-butyric acid (BHBA) were determined in all samples. Average daily milk production of all cows was measured on days 30 and 60 of lactation. The results showed that the differences in BCS between the dry period and puerperium, or the dry period and the 60th day of lactation, were within physiological values in the experimental group of cows, and higher than physiological values in the control group. Glucose concentration was statistically significantly higher in the experimental group than in the control group of cows 10 days before calving (p<0.05) and 15 days after calving (p<0.01). Fifteen days after calving, the BHBA concentration in the control group of cows was significantly higher (p<0.01) than in the experimental group. On days 30 and 60 of lactation, the milk yield of experimental cows was higher than of those in the control group, but the difference was not statistically significant. The obtained results indicate that energy supplements should be used as an integral part of the feed ration during the peripartal period in order to prevent changes in the body condition score of cows by more than 0.7 points, and also that, in cows with a daily milk production of up to 30 l, an energy supplement has a stimulatory effect on milk production until the establishing of an energy balance, in this case, until around the 30th day following calving. .

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.

Two experiments were carried out to measure effects of body condition at calving and different levels of feeding after calving on milk and subsequent reproduction.In experiment 1, which was conducted in two consecutive years, 162 cows (77 in year 1 and 85 in year 2) were group feed so as to reach a target body condition (condition scores ranging from 3-6) four weeks before calving. During the last four weeks before calving, all cows were managed so as to maintain their individual condition scores. At calving, cows in similar condition of similar breed and with similar previous milk production were allocated to high and low levels of feeding at pasture for the first five weeks of lactation. Mean pasture intakes were 13.0 and 7.0kg dry matter (DM)/cow.d in year 1 and 15.0 and 8.5 kg DM/cow.d in year 2In experiment 2, 40 cows were offered pasture and hay from 20 weeks before calving to achieve a body condition score of either 4 or 6 by two weeks before calving. During the first five weeks of lactation, cows were individually fed in stalls on freshly cut pasture at one of three levels of intake, 7 or 10 kg DM/cow.d or .In both experiments cows were grazed as one group from week 6 to 20 of lactation.Improved body condition at calving resulted in an extra 4.0, 11.0 and 7.4 kg milk fat per unit condition score over 20 weeks of lactation, for year 1 and 2 of experiment 1, and experiment 2, respectively. Cows in poorer condition partitioned a higher proportion of feed energy to liveweight at the expense of milk production than did the cows in better condition. However, increasing the plane of nutrition in early lactation resulted in higher levels of milk production and reduced the need for cows to mobilize bodyreserves. Improved body condition at calving had a positive effect on milk fat percentage, particularly in early lactation, but did not affect milk protein percentage. Input-output relations calculated from the experimental data showed that the benefit sf to improve body condition before calving was less than that of additional feeding after calvin changes in the condition of the cows were taken into consideration (25.8 vs 1 4.6 kg DM to yi kilogram of milkfat). Improvements in condition and feeding in early lactation reduced the anoestrus interval after calving by 5.7 d for each additional condition score at calving and 1. d for each additional kgDM/cow.d fed over weeks 1-5 of lactation. The input-output relations resented will enable farmers to assess the likely consequenes of changes in their feeding management in the crucial peripartum period with a greater degree of confidence than in the past.

Cattle Reproduction

The objective of this study was to confirm the relationship among body condition score at the time around parturition, milk yield in subsequent lactation, reproductive efficiency and BCS development in Czech Fleckvieh dairy cows. The BCS and milk yield were measured once a month and the cows were divided into groups according to their BCS before and after calving. Next, data from the database of cattle reproduction of the Czech Fleckvieh herd book were used. The dataset was analyzed by multifactorial analysis of variance using procedures COOR and GLM of the statistical program SAS. Cows with lower BCS in the 1<sup>st</sup> month after calving showed an increase in both milk yield and fat and protein corrected milk (FPCM) yield. No significant relationship was found between the BCS level before calving and subsequent milk yield. The body condition level in the last month before parturition influenced its subsequent decrease in the first phase of lactation. The group of cows with the highest BCS level before calving retained a high BCS level in the first five months of lactation. Adequately, the group of cows with the lowest BCS in the first month of lactation had the lowest BCS in the next four months. BCS before calving was not related to reproduction indicators, but the significant effect of BCS in the 1<sup>st</sup> month after calving on the length of calving to the first service interval was confirmed. The group of cows with BCS > 3.5 in the 1<sup>st</sup> month after calving had the most favourable reproduction indicators, also when the milk yield level was taken into account.
