Abstract

A number of reproductive biotechnologies are currently available to multiply offspring from high genetic merit animals to enhance reproductive efficiency and profitability both in dairy and beef herds. Some of these technologies such as fixed time artificial insemination (FTAI), when correctly...

Abstract

The objective of this study was to evaluate the efficacy of intravenous infusion of hypertonic glucose for recycling of the cows with postpartum anestrus. One hundred true anestrus Holstein-Frisian cows with ≥60 days in milk (DIM) according to the ultrasound examinations were selected from a dairy...

Abstract

The objectives of the study were to evaluate reproductive performance in cows synchronized with the Ovsynch protocol at different stages of the estrus cycle as detected by pedometry, and to compare the reproductive performance of cows inseminated by Ovsynch in different stages of the estrus cycle...

AbstractFull Text

The study included 14 high producing multiparous suckled crossbred cows with poor to fair body conformation and history of parturition 7 months prior. The cows after thorough gynaeco-clinical examination were diagnosed as postpartum anestrous/subestrous. The animals were fed mineral mixture per...

Abstract

Cross sectional study was conducted in Alage dairy farm with the objectives of determining the causes of reproductive wastages, their prevalence and the risk factors on 173 dairy cows (68 Holstein Friesian (HF) and 105 Borena breed) from November 2017 to April 2018. Additionally, a one year data,...

Abstract

Fertiliy rate in high milk-yield dairy cows, with prolonged postpartum anestrus, was investigated after treatment by Ovsynch protocol. Thirty cows with follicular cysts orunovulated follicles (around 1.2 cm in diameter), without detected estrus up to 60 days post partum, were treated by Ovsynch...

Abstract

The aim of this research was to compare two artificial insemination protocols (AIP): hormonal synchronization with fixed time artificial insemination (SC-FTAI) and the use of a table based on visual observation of estrus signs (VO) in order to identify cows in natural or spontaneous estrus being...

Abstract

Artificial insemination of beaf cattle is a technology that allows producers to bring genetic improvement to their herds. Estrous synchronization is the technology that allows artificial insemination to occur more effectively and efficiently. Recent research has brought many new estrous...

Abstract

Reproduction is critical for the success of both dairy and beef cattle production. Inadequate reproduction impairs profitability by compromising production, delaying genetic progress and increasing expenses. A major impediment to the use of artificial insemination (AI) is the ability to detect...
