“…The intensity of the magnetic field is affected by the different crosssections of the body. The birth weight of male calves is higher than female calves [12]. The cross-sectional area is directly proportional to the surface area of the emitting object.…”

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.

“…Information about calf birth weight (CBW), expected mature live weight (MW) and weight gain (WG) was not available from the survey and, therefore, was estimated based on literature representing the Indonesian situation. CBW per animal was assumed to be 40 kg [ 20 ], MW per animal was assumed as 500 kg, and WG per animal was assumed to equal 450 g/d [ 21 ].…”

Objective: This study was conducted to provide models to accurately predict nitrogen (N) and phosphorus (P) excretion of dairy cows on smallholder farms in Indonesia based on readily available farm data.Methods: The generic model in this study is based on the principles of the Lucas equation, describing the relation between dry matter intake (DMI) and faecal N excretion to predict the quantity of faecal N (QFN). Excretion of urinary N and faecal P were calculated based on National Research Council recommendations for dairy cows. A farm survey was conducted to collect input parameters for the models. The data set was used to calibrate the model to predict QFN for the specific case. The model was validated by comparing the predicted quantity of faecal N with the actual quantity of faecal N (QFNACT) based on measurements, and the calibrated model was compared to the Lucas equation. The models were used to predict N and P excretion of all 144 dairy cows in the data set.Results: Our estimate of true N digestibility equalled the standard value of 92% in the original Lucas equation, whereas our estimate of metabolic faecal N was –0.60 g/100 g DMI, with the standard value being –0.61 g/100 g DMI. Results of the model validation showed that the R2 was 0.63, the MAE was 15 g/animal/d (17% from QFNACT), and the RMSE was 20 g/animal/d (22% from QFNACT). We predicted that the total N excretion of dairy cows in Indonesia was on average 197 g/animal/d, whereas P excretion was on average 56 g/animal/d.Conclusion: The proposed models can be used with reasonable accuracy to predict N and P excretion of dairy cattle on smallholder farms in Indonesia, which can contribute to improving manure management and reduce environmental issues related to nutrient losses.

“…Aprily et al [28] menyatakan bahwa kejadian pedet mati saat lahir disebabkan banyak faktor diantaranya pedet mengalami abses di persendian, prematur dan gangguan syaraf. Kematian pedet fase perinatal yaitu saat lahir sampai 24 jam setelah lahir juga dapat disebabkan minimnya manajemen kelahiran oleh peternak seperti kurangnya pengamatan menjelang kelahiran dan jumlah ternak sapi dalam satu kelompok (herd size) [29].…”

Pada sapi perah abortus dan pedet mati saat lahir (stillbirth) menempati persentase paling besar penyebab kegagalan lahir dan kematian pedet pasca lahir yaitu masingmasing sebesar 41,07% dan 40,18% [28].…”

Objective: To determine the natural mating behavior pattern of PO bulls with Bali cows in the cattle breeding system using freestall housing of “Litbangtan Model”.Methods: The materials were 63 livestock; 3 PO bulls and 60 Bali cows. The study was designed with a randomized block design (RBD) with three treatments based on the physiological status of Bali cows; namely Treatment A: 20 heifers, Treatment B: 10 heifers and 10 cows, and Treatment C: 20 cows. The parameters observed were the pattern of estrous behavior, the length of time from estrus to mating, the phenomena that occurred during pregnancy and the birth process, and the pregnancy rate.Results: The estrous intensity in the +++ category was higher than + or ++ in all treatments. The shortest average time interval between estrus and mating occurred in treatment A with a pregnancy rate of 83.33%. The phenomena that occur during pregnancy and at birth are abortion, dystocia and calf death at birth. Abortion occurs at 4-6 months of gestation, dominated by heifers; the incidence of dystocia is entirely experienced by heifers.Conclusion: Cows with estrus were 86.67% with various expressions starting from silent heat (+), medium (++) and visible (+++). There are 42 Bali cows that show normal behavior in a series of reproductive activities (estrus and mating) with a time interval estrus and mating between 0.67-14.75 hours. Pregnancy rate 83.33%; the phenomena that occur during pregnancy and childbirth include abortion, calf death at birth and dystocia.
