Body Condition Scores

The present study aimed at evaluating the influences of different concentrate feed proportions in the ration offered to dairy cows post partum with different body condition scores (BCS) before calving. Therefore, 60 pluriparous cows were divided 42 days before expected calving into two groups with a higher or an adequate BCS. After calving, both groups were further subdivided into a group fed a ration with either a low concentrate feed proportion (C, 35% at dry matter basis) or a high (60% at dry matter basis) one. It was hypothesized that different BCS would lead to different reactions concerning varying concentrate feed proportions. Isolated BCS effects were detected in the white blood profile only before calving. Neither low nor high concentrate feed proportions affected hematological, blood immune cell phenotypes and inflammatory markers consistently irrespective of BCS group. It was concluded, that the assessed BCS span covered a range in which the capability of cows to cope with different dietary post partum energy supply remained unchanged.

Body Condition Scores

AbstractChanges in live weight, body condition, milk production and composition were monitored for single- and twinsuckling cows in two experiments. In experiment 1, all cows were managed for 3 months before calving to achieve condition scores at calving 2·1 (low) and 3·1 (moderate). Subsequently, these animals were placed on a fixed level of energy intake (80 MJ metabolizable energy (ME) per day) for 16 weeks. Post-partum diets contained differing amounts of digestible undegradable protein (DUP), but similar amounts of effective rumen degradable protein (ERDP). In experiment 2, single- and twin-suckling cows were fed to achieve a condition score at calving of around 2·75. These animals were subsequently placed on two levels of energy intake (80 MJ and 130 MJ ME per day) during the first 16 weeks of lactation. The diets providing these energy intakes also contained differing amounts of DUP. Neither the level of DUP in the diet nor the level of feeding significantly altered the digestibility of the dry matter or organic matter in the dry matter of the experimental diets.Body condition at calving had little effect on daily milk yield (9·5 kg) and composition (33·5 g/kg fat; 30-0 g/kg protein) in experiment 1. Cows with higher body condition scores at calving lost 13·5 kg more live weight and 0·26 units more body condition (P < 0·05) during the 1st month post partum but remained in better condition throughout the trial period than cows with lower body condition scores. Cows on 130 MJ ME per day produced higher (P < 0·001) daily yields of milk, milk fat and protein (+2·0 kg; +151 g; +85 g) and lost 57 kg less live weight and 0·52 units less body condition (P < 0·001) than cows on 80 MJ ME per day. Elevated dietary levels of DUP promoted (P < 0·05) daily milk yields (by 1·25 kg) and reduced live-weight and body condition-score loss during the 1st month post partum in both experiments. Twin-suckling cows produced the highest average daily yields of milk throughout the 16-week trial period in both experiments but yields were not significantly higher after early lactation in experiment 1. Cow body condition score at calving and the level of DUP in the post-partum diet of cows had no effect on the post-partum performance of calves. Twin calves had slower growth rates (P < 0·001) than single calves (0·65 and 1·07 kg/day respectively) in experiment 1. However, twin calves sucking cows on 130 MJ ME per day in experiment 2 grew similarly to single sucking calves from week 8 of lactation (0·8 kg/day).

The aim of this study was to evaluate energy metabolism and lipid mobilization via ultrasonic measurements (USM), considering inner fat depots, in lactating dairy cows differing in body condition score (BCS) and fed rations with low (35% at dry matter basis; C35) or high (60% at dry matter basis; C60) concentrate feed proportions postpartum. Sixty pluriparous German Holstein cows were arranged in a 2 × 2 factorial design from d 42 antepartum (relative to calculated calving) until d 120 postpartum. Animals were divided into a group with a lower (initial BCS = 3.1 ± 0.38 SD; BCSL) and a group with a higher (initial BCS = 3.83 ± 0.41 SD; BCSH) BCS. Due to higher dry matter intake C60 groups reached the positive energy balance earlier, whereas C35 groups had a more pronounced negative energy balance. Although this would suggest a more pronounced mobilization of C35 groups the USM revealed no differences between feeding groups. Differences in BCS between both BCS groups remained almost the same over the trial. This was not reflected in ultrasonic data, as lipid mobilization was higher in higher conditioned cows. These findings demonstrate the extended possibilities of USM to depict metabolic processes.

Condition Score

Subclinical ketosis is a metabolic disorder which often goes undiagnosed and leads to constricted performance and an impairment of general condition. In the current study subclinical ketosis was characterised by a β-hydroxybutyrate (BHB) concentration of >1·2 mmol/l in blood serum. To generate this metabolic situation, an animal model was created. The model, based on group-specific interaction of dietary energy supply and body condition, is appropriate for testing the medical effectiveness of treating this kind of ketosis and its concomitants. During the trial, 18 dairy cows (primiparous and pluriparous) were assigned, according to their body condition score (BCS) 6 weeks before expected parturition, to a normal [6·78 MJ net energy for lactation (NEL)/kg dry matter; 20% concentrate] or to a high-energy feeding group (7·71 MJ NEL/kg dry matter; 60% concentrate). Therefore cows with the highest BCS were allocated to the high-energy group to enhance the contrast with the control group. Statistical analysis was done using the MIXED procedure of SAS. Effects were declared significant when P-values were ⩽0·05. Owing to the higher energy concentration and dry matter intake, the energy intake and balance was significantly higher in the high-energy feeding group, with strong effects on lipid metabolism and health in blood and liver post partum. Within the first 2 weeks after calving, 8 out of 9 cows (89%) of the high-energy group had BHB values indicative of subclinical ketosis. These cows also had significantly higher values of non-esterified fatty acids (NEFA), aspartate transaminase (AST) and glutamate dehydrogenase (GLDH) post partum, as well as a raised total lipid content of the liver. RQUICKI, a calculated parameter which is based on serum concentrations of glucose, insulin and NEFA to assess the insulin sensitivity, was not affected by treatment. Therefore, RQUICKI does not seem to be the right parameter for diagnosing decreased insulin sensitivity in cows affected by subclinical ketosis. The milk fat and the fat:protein ratio of the high-energy group was also higher, even though there was no decrease in milk yield for cows with subclinical BHB values.

AbstractThe relationship between body condition at calving, uterine tone and discharge, time to first oestrus and changes in concentration of serum calcium and magnesium in early post partum was examined in 209 multiparous dairy cows located in four herds in the San Joaquin Valley of California. Body condition score (BCS) was graded from 0 to 5 and BCS at calving was estimated from BCS in the late dry period (LDBCS). Uterine tone and discharge were graded from l(best) to 3(worst) after rectal palpation at two weeks post partum. Concentrations of blood metabolites and levels of progesterone were determined from blood samples taken at selected stages of lactation from the late dry period to ten weeks post partum. Abnormal uterine discharges were strongly correlated with uterine tone. Uterine tone and discharge scores were significantly lower in cows that calved with body condition scores of 2.5 and 3.0 than in those which calved with body condition scores of < 2.5 and ≥ 3.5. Serum calcium and magnesium concentrations were higher at two weeks post partum in cows with scores of 2.5 and 3 than in cows with higher or lower scores. Serum calcium and magnesium concentrations appeared to be higher with decrease in grades of uterine discharge and tone but this was significant only in the case of serum calcium and uterine discharge. The number of days to first oestrus was significantly associated with uterine discharge and tone (P < 0.05) but not significantly associated with LDBCS. The number of days to second oestrus was not significantly associated with uterine discharge and tone but was significantly less in cows with LDBCS 3 (17.28 days) than cows with lower or higher LDBCS (P < 0.05). It is concluded that body condition at calving is associated with serum micromineral balance and subsequent uterine and ovarian health. Based on these measurable indicators, cows calving with body condition scores of 2.5 and 3 appeared to be in optimum condition for post partum reproductive performance.

The objective of this study was to determine the content of the feed given and reproductive status of each animal and its effect on reproduction performance in early lactation dairy cows. Seven early lactation of Friesian Holstein cows were used from local farmer. The observed variable were feedstuff from local farmer and reproductive status (post partum estrous and service per conception). The results of proximat and van soest analysis from feedstuff consist of elephant grass (Pennisetum purpureum) and concentrate feed from feed mill. The elephant grass (Pennisetum purpureum) was contained of dry matter (DM) 86.27%, Ash 18.63%, extract eter (EE) 3.84%, crude fiber (CF) 30.62%, crude protein (CP) 13.05%, neutral detergent fibre (NDF) 73.73% and acid detergent fiber (ADF) 45.31%. Concentrates feed was contained of dry matter (DM) 89.24%, Ash 15.36%, extract eter (EE) 5.37%, crude fiber (CF) 17.11%, crude protein (CP) 12.76%, neutral detergent fibre (NDF) 58.23% and acid detergent fiber (ADF) 19.20%. The results of reproductive parameters for post partum estrous (PPE) 121.43±16.672 days and service per conception (S/C) was 2.14±0.690. In conclusion the feedstuff were given less meet the requirement, and affecting the performance of reproduction.
