Abstract
Scientific data on the length of parturition stage, placental weight, and the number of placentomes in Ongole (PO), Simental Ongole (SimPO), Limosin and Ongole (LimPO) breeds in Yogyakarta Province are not yet known. This research aimed to study parturition stage, placental weight, and placentomes number on beef catlle in small holder farm. This research was carried out on small farmers in the Special Region of Yogyakarta Province. There were 22 PO, 7 simpo, and 4 limpo cattle. The first study determined length stage of parturition. The second study determined the weight of the placenta and the number of placentomes. Data collected were analyzed descriptively. The results of first stage in PO, SimPO, and LimPO cattle were 73.7, 44.5, and 62. 9 hours. The duration of second stage in PO, SimPO, and LimPO cattles were 58.1, 78.7, and 24.5 minutes. The duration of third stage in PO, SimPO, and LimPO cattle were 4.3, 4.8, and 3.5 hours. The placenta weight in PO and SimPO cattle showed that the average of placenta weight was 4.1 and 3.6 Kg. The number of placentomes in PO, SimPO, dan LimPO cattle were 92.5, 92.8, and 102.6. This research showed that the average of stage I in PO was longer than SimPO and LimPO, stage II and stage III in SimPO was longer than PO and LimPO. In addition, the average of placenta weight in PO was heavier than SimPO and LimPO cows. The average number of placentomes in LimPO was higher than PO and SimPO cattle.
Highlights
Reproduction cycles are started from puberty, oestrus, mating, gestation and parturition process
Our findings were different with previous study, stadium III of parturition usually take 30 minutes - 8 hours [2], 6-12 hours [3], and 6 – 8 hours [7]
The factors that may affect the stadium of parturition were physical factor, hormones, nutrition, and breed
Summary
Reproduction cycles are started from puberty, oestrus, mating, gestation and parturition process. Symptoms that may occurs before due date was the change of mammary gland development and relaxation of the pelvic ligaments but these symptoms are very high variable and inconsistent and cannot be used precision delivery [15]. Parturition is divided into 3 stages, namely stage one cervical dilation, stage two fetal expulsion, and stage three placental expulsion [2 and 3]. Stage two fetal expulsion lasts 2-4 hours, if more indicates dystocia [2], Stage 3 lasts between 6 to 12 hours [3]
