Abstract

ABSTRACT. The aim of the study is to determine the relationship between body condition score with reproductive disorders, reproductive performance and estrus performance in beef cattle. Sixty beef cattle were used in this research. Body condition score (BCS), reproductive disorders, reproductive performance and estrus performance were measured in this research. Data were analyzed using correlation and simple linear regression. The results in this research showed that the relationship between BCS and reproductive disorders, condition of vulva, behavior, intensity of mucus and uterine erection had no significant effect (p 0.05) with the value of the regression equation and the correlation coefficient respectively Y = 4,964 - 0,57X and 0,12; Y = 2.235 + 0.14X and 0.26; Y = 1.788 + 0.89X and 0.153; Y = 2.343 - 0.12X and 0.23; Y = 1.352 + 0.1X and 0.198. BCS with Service per conception, Days open, Conception rate and Estrus post partum showed significant results (P 0.05) with the value of the regression equation and the correlation coefficient Y=2.266-0.201X and 0.35; Y = 107.35-3.56X and 0.33 and Y = 96.923-4.385X and 0.499; Y = 87,891 - 4,189X and 0,508. The conclusion of this study is that Body condition score has a significant effect on Service per conception, Days open, Conception rate and Estrus post partum.

Abstract

This study aimed to analyze the relationship between quantitative traits and reproduction traits of Ongole grade cows in Rembang Regency. This study was done from May to July 2022. The number of samples used was 224 Ongole grade cows that have given birth at least once. Quantitative traits were obtained by measuring body condition scores (BCS), body length (BL), body height (BH) and chest circumference (CC). The class was based on Indonesian National Standards for Ongole grade cow breeding cattle in 2015 (Class I, II, III and Non-Class). The BCS used is the American system for beef cattle (score 1 to 9). The BL and BH were measured with a measurement stick. The CC was measured using the weight body Round-O (WB Round-O). The reproductive traits measured included service per conception (S/C), calving interval (CI), days open (DO) and estrus postpartum (EPP), which were obtained by observing cattle and interviewing breeders and inseminators. The analysis used was descriptive statistical analysis with averages and percentages and non-parametric analysis of Spearman’s correlation test.  This research concludes a significant relationship between quantitative traits and S/C with a very weak negative direction and strength of the relationship.

Abstract

This study seeks to comprehensively assess the impact of Rumen Protected Choline (RPC) supplementation on key parameters in dairy cows, including dry matter intake, milk yield, milk fat and protein composition, first estrus, open days, and Service per Conception (S/C). This research utilizes a quantitative meta-analysis methodology to systematically evaluate and synthesize data. The treatment used is supplementation Rumen Protected Choline and the basal diet for control. Observed parameters include dry matter intake (DMI), milk yield (MY), milk fat content (MFC), milk protein content (MPC), service per conception (S/C), first estrus (FE), and open days (OD). The study went through five stages, namely database preparation, meta-analysis implementation, heterogeneity testing, summary effect testing, and publication bias measurement. Tools used include PDF software for filtering journals and data processing applications such as Microsoft Excel, OpenMEE Software, and Review Manager 5.4 for data interpretation. Based on the results of the meta-analysis, it is found that RPC supplementation significantly affects (p<0.05) the increase in milk production, milk protein content, and milk fat content. It is also capable of reducing S/C and open days, but it does not affect dry matter intake and first estrus. The findings of this study, derived from a meta-analysis, indicate that while RPC supplementation has no impact on feed intake, it significantly influences reproductive parameters.

Abstract

The processing of young deer antlers exemplifies the use of deer as wildlife, guided by the principle of continuity and without harming them. The purpose of this study was to determine the effect of young Timor deer antler meal and to determine the impact of its supplementation on the size of the testes of male Wistar rats. Twenty male Wistar rats with a body weight of 200–250 g and an age of 90 days were used. The samples were divided into four groups: a control group and three treatment groups of young Timor deer antler meal at doses of 25 mg kg-1 BW-1, 50 mg kg-1 BW-1, and 100 mg kg-1 BW-1. Ca and Zn measurements were carried out using an atomic absorption spectrophotometer at the Feed Nutrition Laboratory of Diponegoro University. The size of the left and right testes (length, width, diameter, and weight) was analyzed using Analysis of Variance, and Duncan's Multiple-Range Test was used for testis weight. Data on Ca and Zn content were analyzed descriptively. Therefore, it can be concluded that supplementation with young Timor deer antler flour affected testicular weight, but not testicular length, width, and diameter. The results showed a significant difference (P<0.05) in testicular weight parameters, and testicular length, width, and diameter were not significantly different. Therefore, it can be concluded that supplementation with young Timor deer antler flour affected testicular weight, but not testicular length, width, and diameter.

Abstract

Objective: This research aims to measure the intensity of magnetic field of different sex of fetuses and the accuracy of pendulum method for the sex detection of cow fetuses.Methods: Twenty-six Madura cows with gestational age of more than 4 months were used in this research. This research is composed of three steps : 1). Measuring the intensity of the magnetic field on the fetus using an Electromagnetic Field Meter (EMF) type 827 which is affixed to the right side of the abdomen 2). Observe the pattern of the gold ring pendulum used for sex detection of cow fetus 3). Measure the accuracy of the pendulum ring gold method. The data were analyzed using descriptive analysis.Results: The result of this research showed that the intensity of the magnetic field of a male fetus is 0.04 µT for a head, 0.07 µT for back, 0.05 µT for abdomen and 0.03 µT for tail. Magnetic field of a female fetus is 0.03 µT for head, 0.05 µT for back, 0.035 µT for abdomen and 0.01 µT for tail. The gold ring pendulum is a unidirectional pattern for detection male sex showed the accuracy of 91.67% and a rotating pattern for female fetuses showed accuracy of 85.71%. The average accuracy of detection using the gold ring pendulum is 88.46%.Conclusions: The conclusion of this research is male fetuses have a magnetic field higher than male fetus.
