This study aims to determine the risk factors for dystocia in primiparous and pluriparous dams at site. Cases of dystocia, both maternal fetal, were obtained as secondary data from records Situbondo Regency Animal Husbandry Service year 2020 2021. Tracking on these was carried out look cows experienced owners’ names addresses interviews using a questionnaire worksheet. Interviews conducted Febr...

Out of 5970 calvings, 4.29% had an abnormal course (dystocia). The occurrence of stillbirths was 6.98% of all births and 4.15% of normal course births. Stillbirths occurred in 70.31% of dystocias. The highest frequency of stillbirths was in Blonde d ́Aquitaine (8.59%) and the lowest in Gasconne (3.96%) cows. A narrow pelvis and an oversized foetus were the causes of more than 50% cases of dystoc...

The aim of the study was to evaluate oxidative stress in cows undergoing normal parturition and cows suffering from dystocia. The erythrocytic glutathione peroxidase (GSH-Px) activity, plasma vitamin A and ß-carotene concentrations, and paraoxonase PON1 activity were lowered (P<0.001, P<0.01, 0.05, and 0.05, respectively) in cows with dystocia compared to normal calving cows. The erythrocytic m...

Dystocia scores were recorded by producers on 120,434 Holsteins (218,213 records) from 1985 through 1996; dystocia scores 3 to 5 were coded as difficult births. Stillbirths were recorded for deaths within the first 48 h after birth. Data were restricted to registered cows for pedigree completeness, and inbreeding coefficients were calculated using 5-generation pedigrees. Computational restricti...

Information from 7712 lactations of Holstein dairy cows was collected from 33 commercial herds around Ithaca, NY in the 3 yr from 1981 to 1983. The data were divided into subsets corresponding to lactation 1, lactation 2, and lactation 3 or greater. To estimate heritabilities of dystocia, retained placenta, metritis, ovarian cysts, milk fever, and mastitis, a mixed linear model (herd-year fixed...

The underlying causes of labor dystocia can be various. Lack of expulsive forces or fetal malpresentation are amongst the most common ones. However, pelvic masses are described as well. Here we describe two cases of labor dystocia as first presentation of pelvic malignancy.

An evaluation of natuml twinning in beef cattle revealed that cows birthing twins had shorter (P c .Ol) gestation lengths, more (P e .Ol) retained placentas, more (P < .01) dystocia, more (P e .01) days to e m s , lower (P e .01) conception rates and more (P < .01) days to pregnancy than cows birthing singles. Days to estrus, conception rate and days to pregnancy were not affected by number of ...

The objective of the present study was to examine the factors associated with the death of neonatal lambs. Postmortem autopsy data were collected from 3198 newborn lambs in the Sheep CRCs Information Nucleus Flock situated in various environments throughout southern Australia. The proportion dying by category from highest to lowest was starvation-mismothering (25%), stillbirth (21%), birth inju...
