Abstract

Placental retention or retensio secundinae is one of the reproductive disorders that often occurs in dairy cows. This will interfere reproductive efficiency, including Days Open and Calving Interval. Retained placenta is defined as the failure to completely pass all of the placenta from the uterus (cotyledon villi) for more than 8 hours after parturition. This study aimed to determine the relationship between parity and placental retention and its impact on lambing days and lambing distance in dairy cows. The research was conducted at North Bandung Cattle Farming Cooperative (KPSBU) Lembang. The method used was data analysis using descriptive analysis and path analysis. The results showed that parity has a significant relationship with placenta retention, and placenta retention with increasing parity can affect days open and calving interval in dairy cows at KPSBU Lembang. Path analysis found that the t-statistical results had exceeded 1.96 with a significant p-value that did not exceed 0.05, so there was a significant relationship between the variables in the study. Dairy cows that have experienced retained placenta at North Bandung Cattle Farming Cooperative (KPSBU) Lembang have low reproductive efficiency, characterized by long open days and calving intervals exceeding the expected time.

Abstract

The availability of dairy cow milk in Indonesia is still insufficient to meet domestic needs, one of which is caused by the declining dairy cow population due to infectious diseases, namely FMD (Foot and Mouth Disease). Not only does it cause economic losses, FMD also results in a decline in the reproductive status of dairy cows. To assess whether a cow's productivity level is good or not, it can be determined quantitatively by calculating several reproductive efficiency parameters, namely Service per Conception (S/C), Conception Rate (CR) and Pregnancy Rate (PR). The aim of this research is to describe the reproductive efficiency of post-FMD dairy cows based on S/C, CR and PR values. This research used a descriptive approach to data from 1,046 sample animals taken from the KPSBU Lembang recording system, which was then tabulated using the Excel program. Based on the calculation results of reproductive efficiency parameters, the S/C value was obtained, namely 1.635 times, where this value is in the normal category. Meanwhile, for the CR and PR parameters, the values obtained are 49% and 61%, which shows that these values are below the normal.

Abstract

Beta-lactoglobulin genetics is one of the whey proteins in cow's milk that can influence improvements in milk composition, production, and component levels. Reproductive disorders and clinical mastitis in livestock are often related to genetic, hormonal, and environmental factors. Research on the relationship between beta-lactoglobulin and cow reproduction is still very limited. Therefore, the aim of this study is to determine the relationship between beta-lactoglobulin genotype and clinical mastitis as well as reproductive disorders (dystocia, retained placenta, and endometritis). This research utilizes secondary data obtained from the KPBS Pangalengan headquarters, consisting of genotype examination results of betalactoglobulin and medical records of cows experiencing clinical mastitis and reproductive disorders. A total of 113 samples were collected. The data were analyzed using quantitative methods, followed by ChiSquare tests using Microsoft Excel and SPSS version 25.0 for data analysis. The results showed that the beta-lactoglobulin genotype was not associated with the incidence of clinical mastitis (p=0.509) or reproductive disorders such as dystocia (p=0.789), retained placenta (p=0.193), and endometritis (p=0.685). All test results indicated significance values ≥0.05. The conclusion of this study is that polymorphism beta-lactoglobulin does not have a significant relationship with clinical mastitis and reproductive disorders occurring in Friesian Holstein cows at Pangalengan area.
