The research took place on a farm in North-Eastern Romania with Holstein Friesian cows aged between 3 and 9 years. Bacteriological investigations were carried out throughout the year 2023, total of 35 cows, including 25 multiparous 10 primiparous 23 had eutocic parturitions 12 dystocic parturitions, during first weeks postpartum. In case parturition, biological samples yielded isolates 9.3% strains classified as
Inflammation of the mammary gland leads to a decrease in glandular synthesis, which reduces concentration casein and fat milk. Subclinical mastitis can alter milk's composition varying proportions, depending on pathogenicity causative agent. Detecting subclinical is complex operation, as external appearance not altered, milk secretion shows no visible changes, it appears physiologically normal. Through analysis, somatic cells exceeding allowable limit be detected, along with presence...
Lameness is a major health and economic issue in dairy cattle, leading to reduced milk yield, feed intake, reproductive efficiency, increased treatment costs slaughter rates. Treatment for lameness cattle often prolonged process, lasting several months, due the multifactorial nature of condition complexity its underlying causes. This review highlights lameness, involving environmental, nutritional, disease-related factors, as well systemic local infections. Effective diagnosis, including...
The post-parturition period is the most important stage in recovery of maternal organism after childbirth (1,3,9). High fertility due to parturition surveillance, prevention periparturient infections and resumption reproductive cycle (4,18,22,25). In research (2022-2023), highest share was recorded acute endometritis (20.3% 2022 17.2% 2023), which also shows a decrease chronic (10.4% 9.1% 2023). All these elements achieve differentiation within different gynecopathies: total 20.7%, with...
Puerperium is the period during which body recovering and preparing itself for a new pregnancy. The time needed recovery depends on number of factors, such as: physical condition, maternal health, way parturition took place, feeding conditions, husbandry, environmental conditions (parturition hygiene, stress factors), quality care at supervision puerperium (2,4). Uterine involution after process characterized by series anatomical, cytological bacteriological changes in uterus, whereby...
In equines, the reproductive activity is seasonal polyserial, thus starting with spring months and until autumn there are cyclic estrous manifestations. The of May, June July characterized by a much more pronounced manifestation expression estrus. duration sexual cycle can vary from 9 to 33 days, estrus, on other hand, has variation 2 10 even more. Ovulation takes place 24-48 hours before end heat. oocyte released in metaphase II, moment when be fertilized. Friesian horse breed, intensity...
"Pathological puerperium can mainly cause significant economic damage through the high losses that accumulate throughout herd and especially percentage of sterility infecundity. According to literature data, it is shown this infertility ratio range quite widely between 5.0-30.0% total bull herd. A criterion in occurrence gynecological disease feed, which vary terms quantity quality, farming regime cows are subjected not environmental factors (lack body hygiene, low temperatures during winter...
Although the rates of adolescent pregnancies appear to have dropped according World Health Organization (WHO), decrease in age first menarche and better nutrition seems contribute otherwise high rate pregnancy worldwide, despite efforts different organizations improve upon this trend. We conducted a population-based retrospective cohort study from January 2015 December 2021 using our hospitals' database. totaled 2.954 6.802 adult pregnancies. First, we compared younger adolescents' outcomes...
This review highlights to what extent the embryo transfer (ET) activity in Europe was affected by COVID-19 pandemic. The ET represents a procedure of modern reproductive biotechnologies that is increasingly applied farms animals. Commercial cattle and, albeit lesser extent, other species. For this study, official data reported each country European (AETE) and international (IETS) forums, regarding activities, were accessed. Each has an rapporteur, but procedures are not mandatory. included...
"The evolution of the puerperium is conditioned by course parturition - eutopic or dystocic, but also possible placental retention uterine atony and not rarely infection with bacterial germs. After parturition, energy consumption increases involution, volume milk production needs determined local general self-defence. The puerperal period one most important stages in reproductive cycle cows. Early correct diagnosis conditions during this can lead to appropriate more effective treatment...
Due to the fact that farm wants crossbreed sheep with meat breeds, it was opted for fastest solution bring genetic progress, namely embryo transfer, using from Turcan breed as recipients and those Suffolk donors, so finally batch of receivers after parturition will produce a production lambs. Following selection considering standard criteria include: general health, functional integrity genital tract cyclic activity ovaries, two groups were formed induction synchronization estrus. The first...
