1. Pre-TAI protocol strategies to increase reproductive efficiency in beef and dairy cows
Abstract Ovulation synchronization protocols are well established in beef and dairy cows. However, the protocol response rate is around 70-90%. In beef cows, factors such as inadequate nutrition and calf presence negatively impact the response of progesterone (P4)/estradiol-based ovulation synchronization protocols by interfering with GnRH release and conseq

2. Effectiveness of a low-dose Norgestomet ear implant in short-term protocols to induce estrus in ewes during the non-breeding season in Brazil.
ABSTRACT The objective of this study was to evaluate the reproductive performance of ewes subjected to a short-term protocol for estrus induction using 1 mg of Norgestomet during the non-breeding season in Brazil. A total of 84 ewes were randomly divided into two equal groups (n = 42 per group). Controlled Internal Drug Release (CIDR) containing 330 mg proge

3. Insulin effect during a Heatsynch protocol in dairy cows
RESUMO: O objetivo deste estudo foi avaliar o efeito da administração exógena de insulina sobre crescimento folicular, apresentação de cio e taxa de concepção durante um protocolo de sincronização da ovulação. As vacas holandês lactantes foram submetidas ao protocolo Heatsynch, com inserção do dispositivo intravaginal contendo 1,9 g de progest

4. Effect of eCG on the follicular dynamics and vascularization of crossbred cows with different circulating progesterone concentrations during synchronization of ovulation in an FTAI protocol
RESUMO: Objetivou-se neste estudo avaliar o efeito do tratamento com gonadotrofina coriônica equina (eCG) sobre a dinâmica e função folicular em fêmeas mestiças com diferentes concentrações circulantes de P4 durante a sincronização da ovulação em um protocolo de IATF. Para tanto, foram utilizadas 30 fêmeas mestiças e submetidas a um protocolo d

5. Reproductive performance of fixed-time artificial insemination in swine and factors for the technology success
RESUMO: A inseminação artificial em tempo fixo (IATF) surge como uma biotecnologia para definir o melhor momento para realizar uma única IA, reduzindo o número de células espermáticas por fêmea inseminada. Os protocolos de IATF podem se basear na detecção do estro ou na data de desmame e têm como objetivo sincronizar a ovulação a partir do uso de

6. Investigating cardiolocomotor synchronization during running in trained and untrained males
Introduction This study aims at investigating the coupling of the cardiac and locomotor systems during running in trained and untrained males. Methods Sixteen healthy young males subjects were submitted to an anthropometric evaluation, followed by a treadmill test at 70% to 75% of heart rate reserve. Based on the average velocity, they were divided into two

7. Pregnancy rate in lactating Bos indicus cows subjected to fixed-time artificial insemination and treated with different follicular growth inducers
The objective of this experiment was to evaluate the effects of replacing eCG with FSH or FSH/LH on the diameter of ovulatory follicles (DOF) and the pregnancy rates (PR) of lactating Bos indicus cows subjected to a synchronization of ovulation protocol and fixed-time artificial insemination (FTAI) based on progesterone, estradiol benzoate (EB), PGF2α, and

8. Desenvolvimento de ferramenta de comparação de técnicas de processamento de sinais para determinar fadiga muscular por meio do sinal emg / Toolkit development for signals processing technics comparison to detect muscular fadigue by EMG signal
This study aimed to development of a computational tool for electromyographic signal (EMG) analysis by signal processing techniques to determine muscular fatigue. With Ethics Committee of Federal University of Goiás approve were recorded from the dominant biceps brachii of 10 volunteers, that did not ever had muscular disease. The protocol consisted on get

9. Produção, composição do leite e desempenho reprodutivo de ovelhas Santa Inês alimentadas com rações contendo óleo de canola ou linhaça / Milk yield, milk composition and reproductive performance of Santa Inês ewes fed diets containing canola or linseed oil
The objective in this study was to evaluate the effect of the addition of canola oil (CO) or linseed oil (LO) on milk production and composition and reproductive performance of Santa Inês ewes. In the experiment I, 33 Santa Inês ewes were fed diets containing 50% of roughage (Cynodon dactylon hay). Experimental diets included a control (no oil) and two rem

10. Follicle-stimulating hormone to substitute equine chorionic gonadotropin in the synchronization of ovulation in Santa Inês ewes
The substitution of equine chorionic gonadotropin (eCG) by follicle-stimulating hormone (FSH) in protocols for synchronization of ovulation in Santa Inês ewes was assessed. Ten females were submitted to the insertion of intravaginal sponges containing 60 mg medroxyprogesterone acetate for 10 days; after this period sponges were withdrawn and the animals wer

11. Ovarian response of Suffolk ewes to estrous synchronization using short-term protocol
The efficacy of estrus synchronization using short-term protocol was evaluated by ultrasound exams in Suffolk ewes during the pre-breeding season. The control Group (n = 12) was synchronized by treatment for 12 days with vaginal sponges impregnated with medroxyprogesterone acetate, and 400 IU eCG at sponge withdrawal. Experimental groups I, II and III kept t

12. Dinâmica folicular de vacas de corte tratadas com três protocolos de sincronização da ovulação =Ovarian follicular dynamics in beef cows treated with three protocols of synchronization of ovulation / Ovarian follicular dynamics in beef cows treated with three protocols of synchronization of ovulation
Background: Artificial insemination is an established and viable technique to accelerate the genetic advancement and economic return of the cattle. However, compromises the efficiency of detection of estrus results in low insemination rates. To avoid these problems in beef herd, synchronization protocols have been developed that allow inseminate large number
