“…Biochemical analysis was performed to determine the following parameters: glucose (Glu), free fatty acids (FFA) and T-Cho for evaluation of energy metabolism and total protein (TP), serum albumin (Alb), albumin/globulin ratio (A/G) and BUN for protein metabolism (measured on a Labospect 7080 autoanalyzer; Hitachi, Tokyo, Japan). In the present study, only the cows whose blood samples were collected at both prepartum (between 60 and 20 days before parturition) and postpartum (between 30 and 90 days after parturition) were selected for data analysis of Herds 2, 3 and 4, because the nutritional condition of breeding cattle during both prepartum and postpartum may have marked effects on the duration of the postpartum interval from calving to first estrus [10].…”

“…Several factors, such as the extent of calf suckling, reproductive failure, genetic variation and level of maternal nutrient intake, affect postpartum reproductive performance of beef cows [15,16,18]. Among them, one of the major factors contributing to a prolonged calving to conception interval is inadequate nutrition, which often causes subclinical and/or clinical metabolic diseases [3,10]. Prepartal and postpartal nutritional statuses are also related to the interval between calving and first ovulation in beef cattle [10].…”

ABSTRACT. The study aims were (1) to confirm the effects of nutritional improvement in prepartal and postpartal periods, monitored using the serum metabolic profile test (MPT) and reproductive performance, and (2) to clarify regional characteristics of the MPT results within our jurisdiction by using our MPT database. Experiment 1: Among 42 breeding cattle herds in our jurisdiction mainly fed home-pasture roughage, 3 experimental herds showing subnormal blood urea nitrogen (BUN) levels were selected and compared with 1 representative excellent herd. Dietary remedial measures were implemented from feed analysis in each herd. BUN concentration in all 3 herds increased significantly, and open days postpartum in 2 of the herds were significantly reduced, compared with values before dietary supplementation. Experiment 2: Thirty-seven herds within our jurisdiction were grouped into 3 categories (Area 1, 2 and 3) by location and soil condition of the herd pastureland. The MPT and reproductive performance in cows whose blood samples were collected at both prepartum (60-20 days before calving) and postpartum (30-90 days after calving) were compared among the 3 areas. Significant regional differences were found in prepartal albumin, total cholesterol, BUN, and glucose and postpartal BUN, glucose and open days (P<0.05). Overall, the MPT (especially BUN) might be useful for determining the metabolic nutritional status of breeding cattle herds, particularly those fed home-pasture roughage. Additionally, poor/unsatisfactory reproductive performance of beef breeding cattle herds probably reflects inadequate nutritional content of the diet, possibly arising from regional pastureland differences.

“…Several factors including degree of calf suckling, reproductive failure, genetic variation, and level of maternal nutrient intake are known to affect postpartum reproductive efficacy of beef cows [12,15,16]. Among these, one of the major factors contributing to prolonged calving due to conception interval is inadequate nutrition, which often causes subclinical and/or clinical metabolic diseases [5,12]. Prepartal and postpartal nutritional statuses are also related to the interval between calving and first ovulation in beef cattle [12].…”

Retrospective surveillance of metabolic parameters affecting reproductive performance of Japanese Black breeding cows

This retrospective study was conducted to confirm the relationship between pre- and postpartum metabolic parameters and postpartum reproductive performance and to clarify seasonal characteristics of the metabolic parameters by using our metabolic profile test (MPT) database of Japanese Black breeding herds. In evaluation 1, MPT databases of blood samples from multiparous cows collected prepartum and postpartum were divided into two groups according to calving interval, and each MPT parameter was compared. In evaluation 2, the same MPT databases used in evaluation 1 were divided into two groups according to the sampling period. Significant differences were found in the prepartal total protein and postpartal γ-glutamyltransferase in evaluation 1. In evaluation 2, significant differences were found in the prepartal and postpartal total protein, albumin/globulin ratio, and glucose. Clear seasonal differences in MPT results emphasized the usefulness of the MPT in breeding cattle herds fed home-pasture roughage and suggest that unsatisfactory reproductive performance during hot periods reflects inadequate nutritional content of the diet and possible reduced feed intake due to heat stress.

“…The nutritional status of the cow in the last trimester of pregnancy is a determining factor in the onset of ovarian activity following calving, in turn affecting the interval from calving to conception [1,2]. The nutritional priorities of the animal are three fold: firstly to maintain adequate basal metabolism, secondly, to replenish body reserves lost during the postpartum period and lastly the resumption of ovarian activity [3].…”

With the aim of evaluating how changes in the metabolic status in the last month of pregnancy affects reproductive efficiency, forty six Bos indicus multiparous cows (5.5 ± 2.4 parturitions), were used. Measurements of body weight (BW), body condition score (BCS) and dorsal back fat (BF) were taken in the last month of pregnancy, postpartum period previous to synchronization (average 50 d) and at breeding by natural mating following synchronization with a progestin (average 70 d). Average postpartum days to resumption to ovarian activity were 79.96 ± 16.5 d, and average postpartum days to conception was 88.5 ± 14 d. Days postpartum to resumption of the ovarian activity was positively correlated (0.51, P < 0.01) with days postpartum to conception, also, days postpartum to conception was positively correlated with prepartum back fat (14 d before parturition) (0.44, P < 0.05). It was observed that BF at calving which is an objective measurement had a low correlation with other productive variables such as BCS and BW (always less than 0.39). Body fat might be a more reliable indicator of the current metabolic status of the animal particularly in the last month of pregnancy when the indicators of BCS are somehow more difficult to interpret and subjective.
