Infertility in cows is one of the major problems with great economic implications. The purpose of this study was to identify by global and individual gynecological investigation major ovarian diseases and to determinate their incidence in the relation with hot season at Aberdeen Angus cows. The study was carried out in June 2019 in private unit in Timis county, Romania, on a number of 93 Aberdeen Angus cows in order to determine the prevalence of different ovarian diseases at this breed in a summer season. Gynecological investigations were performed in order to establish the prevalence of ovarian diseases in the summer season. The results showed different pathological entity variation. Thus, 50.22% of the animals taken into study presented ovarian hypofunction, 27.9% presented corpus luteum, 0.93% polycystic ovary with uterine adherences and 7.44% ovarian follicle.

The aim of this study was to increase fertility in sheep by applying modern biotechnology: induction and synchronization of estrous in out of breeding season. The study was conducted during May 2019- July 2019 on 132 ewes, aged between 1 and 6 years, in Covasna county, Romania. The ewes were syncronisated with Medroxyprogesterone (Ovigest, Hypra), Cloprostenol (PGF Veyx Forte, Esteve) and GnRH (Ovarelin, Ceva). After the synchronization, the artificial insemination was performed at 126 ewes by intracervical method. At 29 days after the artificial insemination was performed the diagnosis of gestation using an ultrasound. From 126 animals artificial inseminated, in 121 (91.67%) cases the diagnosis of gestation confirmed the gestation and in 22 cases was confirmed a twin gestation. [ABSTRACT FROM AUTHOR]

The objective of this study was to evaluate the effects of prostaglandins (natural and synthetic analogues) on estrous synchronization in beef cows. The study was carried out between May - August 2019 in a private unit in Timis County, and involved 54 Aberdeen Angus cows diagnosed with ovarian luteal tissue: corpus luteum (n=36 cows), cystic corpus luteum (n= 8 cows) and luteal cysts (n=10 cows). Two products were used for the treatment of this pathology: PGF Veyx Forte (n=27 cows) and Enzaprost (n=27 cows). The interval between hormonal treatment and the onset of estrous was ranging from 48-96 hours. In this trial 83.33% of the animals expressed signs of estrous. In the present experiment the conception rate after the artificial insemination was 71.11%. [ABSTRACT FROM AUTHOR]

Retained fetal membranes is an issue that has been debated over the years, especially regarding the treatment, because it is wanted to implement a therapeutic option that affects, as little as possible the female reproductive life, thus reducing the associated economic implications of this pathology. In this study, we have analyzed the cases of retained placenta in a farm from Brasov county. The aim of this study was to verify the incidence, diagnosis, treatment of the retained placenta in cows and its economic implications. In this study were included 248 bovines that have calving in the interval January 2015-December 2017. Of these, a number of 29 animals have been found with retained placenta, which represents 11.69%. All 29 bovine animals were treated by manual detachment of the placenta. Economic losses stem mainly from the treatment of the retained placenta and the treatment of the uterine infections, as well as from the longer duration of the service period and calving interval.

The purpose of this study was to identify and verify the effectiveness of breeding sows management, intended to optimize the economic performances and correcting negative factors that influence reproductive parameters of them. The research was made in a farm from Mureş County. In this study were followed 100 animals from lines: Camborough, Hypor Libra, Eurohyb, and PIC. The research was focused on several directions: detecting estrus in sows and gilts; the organization of artificial insemination; pregnancy management; the management of parturition and newborn piglets; pregnancy rate and the prolificacy. The animals were divided in 3 groups, depending on the age and number of previous pregnancies. The average number of piglets born at the PIC line was 9.8, and the average number of weaned piglets was 9.5, with a range of 8.6 piglets (group III) and 10.2 piglets (group II). The average number of products produced by the Camborough line was 9,75, with a minimum of 9,6 piglets (lot III) and a maximum of 9,9 piglets (group II). For weaned piglets the average number was 8.75 with values between 8.3 piglets (group III) and 9.2 piglets (group II). For Hypor Libra line the average number of piglets born was 12.35, with values between 12.3-12.4 piglets. The average number of weaned piglets to this line was 11.75, with a minimum of 11.6 (lot II) and a maximum of 11.9 piglets (group III). The average number of piglets born from the Eurohyb line was 9.55, with a minimum of 7.9 piglets (group I) and a maximum of 11,2 piglets (lot III), and the average number of piglets weaned was 8.85 with a minimum of 7.5 piglets (group I) and a maximum of 10.2 piglets (group III).
