Abstract

This study aimed to characterize the profile of milk cattle farmers of the Northwest region of Minas Gerais State regarding the use of artificial insemination (AI) and see the most relevant factors in the perception of farmers for the adoption process of AI. From January to April 2014, 97 milk...

AbstractFull Text

Despite the importance of progesterone on the fertility of lactating dairy cows, the factors that affect post ovulatory progesterone concentration are still unclear. Thus, the aim of the present study was to identify factors associated with the post ovulatory progesterone rise following 1st ...

Abstract

The goals of this study were to assess whether the injection of 1 mg of estradiol cypionate (ECP) at 13 days after service of artificial insemination (AI) increases fertility in the study subject and if the same dose injected in the near estrus (20±1 days) after artificial insemination services...

Abstract

The use of fixed-time artificial insemination (FTAI) provides producers with numerous benefits including the use of superior genetics, shorter breeding and calving seasons, and a more uniform calf crop. However, the cost of implementing FTAI protocols is one of the several drawbacks hindering their ...

Abstract

Greater metabolic demands in high-producing dairy cows are believed to be a cause of sub-fertility in these animals. Previously, supplementation with vitamin B complex molecules has shown benefits in improving milk production, health, and reproductive efficiency of dairy cows. The primary aim of...

Abstract

The objective of this study was to find the optimal proportions of pregnancies from an in vitro-produced embryo transfer (IVP-ET) system and artificial insemination (AI) so that profitability is maximized over a range of prices for embryos and surplus dairy heifer calves. An existing stochastic,...

Abstract

Data from 96 Holstein Friesian cows on a commercial dairy farm were used to investigate whether body condition and serum levels of nonesterified fatty acids (NEFAs) postpartum (pp) affect progesterone (P4) levels, estrous activity, and fertility in dairy cows. The examination period started 14 days ...

Abstract

Genetic selection and nutrition management have played a central role in the development of commercial rabbitry industry over the last few decades, being able to affect productive and immunological traits of the animals. However, the implication of different energy sources in animals from diverse...

Abstract

The aim of this experiment was to evaluate the effects of feeding the combination of β-carotene and vitamins (ADE and biotin) on reproductive performance of grazing beef cows. A total of 430 suckled multiparous Nellore cows (Bos indicus, initial body weigh=417±58 kg) were used in a randomized block ...

Abstract

In dairy production, high fertility contributes to herd profitability by achieving greater production and maintaining short calving intervals. Improved management practices and genetic selection have contributed to reversing negative trends in dairy cow fertility, but further progress is still...
