Repeat Breeder

Background: Repeat breeding syndrome (RBS), an important reproductive disorder of dairy cattle, results in high economic losses in the dairy industry. The study was conducted to determine the factors of repeat breeding in crossbred dairy cows at selected areas of Bangladesh. Methods: A total of 592 breedable cows from 34 farms were examined from Mymensingh and Chittagong district. Seventy cows were identified as repeat breeder cows and another 23 cows were randomly selected as healthy control cows for the study. Results: The number of calving, the interval between first post-partum heat and last service date, number of services failed and consecutive services failed, the number of medications given, and number of suckling were found significantly higher in repeat breeder cows compared to normal healthy cows. Body weight and Body condition score (BCS) were significantly lower in repeat breeder cows compared to normal healthy cows. There were no significant differences in the estrus cycle length and concentrate feeding in both repeat breeder and healthy cows. The lowest occurrence of repeat breeder was recorded in cows fed with a larger amount of green grass. Remarkably, the highest occurrence of repeat breeder was recorded in cows fed with a significant amount of straw. Conclusion: The identified features of repeat breeding syndrome will help in disseminating awareness on factors affecting the occurrence of repeat breeding syndrome in crossbred cows.

Foot lesions are one of the main causes of productivity losses in the dairy industry. In this study, we aimed to estimate the prevalence of claudication and distribution of hoof lesions by associating them with preventive hoof trimming, as well as list the main causes of involuntary discarding and the main health problems reported in dairy farms. The study included 10 farms distributed in 7 municipalities of Rio Grande do Sul state. The body condition score (BCS) and locomotion score (LS) of the cows were assessed. Hoof examination, lesion classification, and hoof trimming of the animals were performed. Of the 492 animals, 38.4% presented lameness and 36% had foot lesions, 81.4% of which were observed in the pelvic limbs and 19.6% in the thoracic limbs. Of the lesions in the limbs, 47.1% were of infectious origin and 52.9% were noninfectious. The main lesions were sole ulcers (31.6%), digital dermatitis (30.3%), thin soles (12%), and interdigital dermatitis (11.2%). Cows aged 4 to 6 years had a higher number of lesions and a higher LS. Preventive hoof trimming reduced the chances of lameness by 55% as the locomotive system was the main sanitary problem and the first reason for involuntary disposal of the farms. The results show that dairy cows raised in a free stall system have a high prevalence of claudication and foot diseases. These data should be taken into account when altering the livestock management of these animals in order to reduce significant economic losses in the herd.

The aim of this study was to evaluate the dynamics of selected indicators of energy, hormonal profile, body condition score (BCS) and their relationships in dairy cows of the Slovak Pied Cattle from 3 weeks before parturition to 9 weeks after. Significant differences were found in the mean values of non-esterified fatty acids (NEFA) (P < 0.001) and β-hydroxybutyrate (BHB) (P < 0.05). According to BCS results, the dry cows were overweight (4.42 ± 0.75 points). After calving the cows lost weight significantly, as the BCS was 3.25 ± 0.30 points at 9 weeks post partum (P < 0.001). The highest concentration of leptin was recorded before calving (26.80 ± 11.47 ng/ml). The concentrations of insulin and ghrelin did not change significantly (an increase in insulin concentrations from 580.8 ± 66.30 IU/ml to 625.50 ± 174.90 IU/ml and a decrease in ghrelin concentrations from 29.25 ± 4.82 pg/ml to 26.57 ± 5.35 pg/ml were found comparing 3 weeks to 1 week before parturition, respectively). Relationships between the hormones showed positive correlation between insulin and leptin (r = 0.220, P < 0.05), BCS and leptin (r = 0.360, P < 0.001), BCS and insulin (r = 0.232, P < 0.05) and negative correlation between leptin and ghrelin (r = -0.235, P < 0.05), BCS and ghrelin (r = -0.257, P < 0.05). These data provide evidence that the variations in the concentrations of leptin, ghrelin, and insulin are related to variations in the BCS. Negative correlation between leptin and ghrelin contributes to the argument that leptin negatively regulates ghrelin.

In recent years, reproductive performance of dairy cows has declined worldwide. The reproductive characteristics of dairy cows should be evaluated to improve their fertility. Dochi et al. (2010) had reported that dairy cows that exhibited early first ovulation gave a low milk yield, had an early recovery of body condition score (BCS) in the postpartum period and a shorter number of days open. The objective of this study was to evaluate the effect of BCS on the functional recovery of reproduction after the birth of the calves. In this study, lactating Holstein cows were placed in free-stall housing equipped with an automatic milking system. The data presented in this study were collected from 48 cows that had calved between December 2007 and October 2010 with an average parity of 3.4 (range 2–6). The reproductive performance and the BCS during the different intervals between calving and the first ovulation were analysed using ANOVA. The conception rate at the first service was 38.1%. The average milk yield (305 days) was 12 299 kg. The first ovulation and oestrus were determined by ultrasonography. The results of the different intervals to the first ovulation are presented in Table 1. The average interval from the start of days in milk (DIM) to the first ovulation, first oestrus and first service; the number of days open; the number of services per conception and the milk yield (kg day–1, by 90 DIM) were 37.4, 54.7 and 110.3 days; 168.2 days open; 2.5 times; and 42.1 kg day–1, respectively. The cows that exhibited early first ovulation (≤21 DIM) in the postpartum period had significantly shorter intervals between the start of DIM and the first oestrus (P < 0.01). However, the days to first service, the number of days open, the number of services per conception and the milk yield (kg day–1, by 90 DIM) did not differ significantly. The BCS in the peripartum period of different intervals to the first ovulation decreased from 3.1 to 2.4 by 150 DIM. This study showed that average BCS of preparturient 50–10 DIM is 3.0. Moreover, the average BCS of parturition is declining to 2.5 (parturition from 70 to 150 DIM). The cows became pregnant after an increase in the BCS (>150 DIM). In conclusion, these results suggest that the delay to the first ovulation in the postpartum period tended to have delayed the oestrus expression in the cows. Moreover, the low level of BCS in the peripartum period, regardless of the number of days of the first ovulation and the first oestrus, potentially influenced the prolongation in the number of days open. To improve the fertility of the cows, it is important to elucidate the factors affecting the fluctuations in the BCS during the peripartum period.

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.

The objectives of the study were to compare the ovarian activity of Holstein-Friesian (CH HF), Fleckvieh (CH FV) and Brown Swiss (CH BS) dairy cows of Swiss origin with that of Holstein-Friesian (NZ HF) dairy cows of New Zealand origin, the latter being used as a reference for reproductive performance in pasture-based seasonal calving systems. Fifty, second-lactation NZ HF cows were each paired with a second-lactation Swiss cow (17, 15 and 18 CH HF, CH FV and CH BS respectively) in 13 pasture-based, seasonal-calving commercial dairy farms in Switzerland. Ovarian activity was monitored by progesterone profiling from calving to first breeding service. CH BS cows produced less energy-corrected milk (mean 22·8 kg/d) than the other breeds (26·0–26·5 kg/d) during the first 100 d of lactation. CH HF cows had the lowest body condition score (BCS) at calving and the greatest BCS loss from calving to 30 d post partum. Commencement of luteal activity (CLA) was later for NZ HF than for CH FV (51·5 v. 29·2 d; P <0·01), with CH HF and CH BS intermediate (43 d). On average, NZ HF and CH HF cows had one oestrous cycle before the onset of the seasonal breeding period; this was less (P<0·01) than either CH FV (1·7) or CH BS (1·6). There was a low prevalence of luteal persistency (3%) among the studied cows. First and second oestrous cycle inter-ovulatory intervals did not differ between breeds (20·5–22·6 d). The luteal phase length of CH BS during the second cycle was shorter (10·6 d) than that of the other breeds (13·8–16·0 d), but the inter-luteal interval was longer (9·8 d v. 7·0–8·0 d). The results suggest that the Swiss breeds investigated have a shorter interval from calving to CLA than NZ HF cows.

The present study was carried out from selected areas at Rajshahi district to evaluate the reproductive performance of dairy cows in relation to breed/genotype, age, parity, body weight and body condition. A total of 500 cows selected and data were collected directly from the dairy farms owner by using pre-tested questionnaires during the period from September 2013 to December 2014. The average reproductive performance (RP) were recorded as age at puberty (AP) 26.42±0.22 m, age at first calving (AFC) 35.48±0.22 m, post-partum heat period (PPHP) 121.85±3.48 days, service per conception (S/C) 1.93±0.04, days open (DO) 136.80±3.57 days and calving interval (CI) 401.04±3.94 days. Genotype had significant effect (P<0.05) on all the reproductive traits except on S/C. Local (L) × Holstein Friesian (HF) genotype showed earlier AP and AFC than L× Sahiwal (SL) and L. Age group had significant (P<0.05) effect on AP, AFC and other parameters were not significant (P>0.05). Middle age groups of cows had shown better RP than others groups. Parities of cows had significant effect (P<0.05) on PPHP, S/C, DO except on AP, AFC and CI. Third parity had better RP than others. The best RP was found in >300 kg BW groups. Body condition score had significant effect (P<0.05) on all RP. Good body condition score (BCS) had excellent RP. Res. Agric., Livest. Fish.7(3): 481-495,  December 2020

This study aimed to evaluate the effects of different pre-calving body conditions on some metabolic indices, health status and reproductive disorders in dairy cows. The study was conducted on a dairy farm in Eastern Slovakia during the pre-partum period (–1 to –10 DIM) and post-partum period (1 to 14 DIM). Total of 84 cows allotted in 3 groups were submitted to clinical examination and body condition score (BCS) evaluation. At the same intervals blood samples were collected for determination of beta-hydroxybutyrate (BHB), non-esterified fatty acids (NEFA), and calcium levels. During the postpartum period the incidence of reproductive diseases, such as metritis, retained placenta, metabolic disorders, such as milk fever, left displacement of abomasum and orthopaedic disorders were recorded. The strongest lipid mobilisation (NEFA elevation), ketone body production, and blood calcium drop were determined in postpartum dairy cows with the highest prepartum body condition score. In conclusion, the dairy cows with different BCS hade a different metabolic response during the postpartum period. The overcondition was connected with stronger lipid mobilisation and calcium drop after calving. Moreover, the higher BCS could contribute to higher incidence of production diseases.
