Pregnancy loss is a major contributing factor to reproductive inefficiency in both the beef and dairy industries. Sires can have significant influence on amount of pregnancy loss; however, this relationship still poorly investigated. The primary objective study was identify sires associated with high or low incidence (between d 30 100 gestation) investigate their effect concentration circulating pregnancy-associated glycoproteins (PAGs). Postpartum multiparous Nelore cows were inseminated...
This experiment evaluated the effects of temperament on physiological, productive, and reproductive responses in Bos indicus beef cows. A total 953 lactating, multiparous, non-pregnant Nelore cows (age = 99 ± 2 mo; days post-partum 51.4 0.3 d; BCS 5.34 0.04; BW 430 kg) were allocated into 8 groups approximately 120 each. Groups assigned to an estrus synchronization + timed-AI protocol at beginning breeding season. Concurrently with AI, blood samples collected, hair clipped from tail switch,...
Objetivo: abordar os avanços e desafios da Cirurgia Geral Minimamente Invasiva (CMI). Materiais Métodos: Constitui-se de uma revisão integrativa, caráter descritivo exploratório. O início pesquisa deu-se através elaboração pergunta norteadora, em que aplicaram-se domínios estratégia PEO. Logo, efetuou-se um levantamento bibliográfico fevereiro 2025 nas seguintes bases dados: LILACS, MEDLINE IBECS via BVS. Dessa forma, selecionaram-se como descritores DeCS, sendo interligados pelo operador...
In order to provide information that may help researchers understand the main cause(s) of differences in bull fertility frequently observed field trials, this study aimed investigate conception rates as well several vitro sperm characteristics different sires unknown utilized a Timed-AI (TAI) program. Suckled Nelore cows submitted same TAI protocol were allocated into eight breeding groups approximately 120 animals each. Frozen semen doses from three Angus bulls and batches each utilized....
Pregnancy detection has evolved over the last few decades and importance of early pregnancy is critical to minimize amount time a cow spends not pregnant.Embryonic mortality (EM) generally considered be primary factor limiting rates in cattle occurs (<day 28) or late ( ≥ day during gestation (day 0 = estrus).In cattle, incidence EM approximately 20 40% 3.2 42.7%.Significant effort been directed toward understanding mechanisms resulting up 17; however, relatively little known about causes...
Five experiments evaluated the effects of supplemental Ca salts PUFA on reproductive function Bos indicus beef cows. In Exp. 1, nonlactating and multiparous grazing cows (n = 51) were assigned to receive (as-fed basis) 0.1 kg a protein-mineral mix + ground corn per cow/d, in addition cow/d 1) (PF), 2) SFA (SF), or 3) kaolin (control). Treatments offered from d 0 20 estrous cycle. No treatment detected serum progesterone concentrations (P 0.83), day luteolysis 0.86), incidence short cycles...
The objective was to determine the effect of sequence insemination after simultaneous thawing multiple 0.5 mL semen straws on conception rate in suckled multiparous Nelore cows. this procedure vitro sperm characteristics also evaluated. All cows (N = 944) received same timed AI protocol. Ten (0.5 mL) frozen from batch were simultaneously thawed at 36 °C, for a minimum 30 sec. One straw per cow used AI. Frozen three Angus bulls used. Timed records included (first tenth) and time removal bath....
This review summarizes strategies to increase overall pregnancy rates TAI protocols, and potential areas for improvement in reproductive management of Nelore cows.Low BCS at calving postpartum loss negatively impacted percentage pregnant females TAI, with primiparous cows being the most sensitive effects low during period.The current recommended replacement heifers (with on day 0) consist intravaginal progesterone device insertion from -35 -23, 0.6 mg i.m. injection estradiol cypionate...
