| Synchronized artificial insemination was used to inseminate cows using different types of sire genetics, including low-accuracy, calving-ease, and high-accuracy. These three calf sire groups were compared to calves born to cows bred using natural service. We found substantial production efficiency grains, carcass merit improvement, and economic value to calves born to cows following a synchronized artificial insemination program with high-accuracy semen included. The economic advantage to the high-accuracy calf sire group was computed to be in the neighborhood of $40 to $80/head, relative to the natural service calf sire group. |

| A bovinocultura de corte é uma das atividades humanas mais relevantes para a economia do Pantanal e do Brasil. O rebanho nacional em 2018 estava em torno de 213,5 milhões de cabeças (IBGE, 2018). Oliveira et al. (2016) estimaram a população de bovinos na planície pantaneira em 3,85 milhões de animais, sendo 70% desta (2,7 milhões de cabeças) no estado de Mato Grosso do Sul e 30% (1,15 milhões de cabeças) no estado de Mato Grosso. A Embrapa Pantanal vem desenvolvendo tecnologias para a ovinocultura de corte no Pantanal desde seu estabelecimento em 1975, muitas vezes em parceria com a Embrapa Gado de Corte. O arranjo de 'projetos+Precoce' estava entre as iniciativas desta parceria, o qual visou o desenvolvimento de tecnologias e sistemas de produção do... |

| O uso de sêmen refrigerado na reprodução bovina tem ganhado destaque em consequência do aumento da inseminação artificial em tempo fixo (IATF) no Brasil, possibilitando a coleta pré-agendada e preparação do sêmen permitindo o melhor uso dessa biotécnica. A principal vantagem que o sêmen refrigerado apresenta é a maior viabilidade espermática, por não passar pelo processo de criopreservação. Recentemente, estudos mostraram maior taxa de prenhez quando comparado ao sêmen congelado, chegando a um aumento de 20% (SILVA et al., 2016, 2017, 2019). O estudo foi conduzido com objetivo de comparar três diluidores comerciais, sendo dois a base de gema de ovo e um a base de lecitina, durante 15 dias, analisando a viabilidade do sêmen refrigerado, com base na... |

| As part of the National Animal Health Monitoring System (NAHMS ), USDA:APHIS:Veterinary Services conducted a national study of beef production, the Beef Cow/Calf Health and Productivity Audit (CHAPA). This study was designed to provide both participants and the industry with information on cow/calf health, productivity, and management practices. Data for Part 1: Beef Cow/Calf Herd Management Practices in the United States, were collected from beef producers September 29 through October 9, 1992. The National Agricultural Statistics Service (NASS) collaborated with VS to select a statistically designed producer sample that represented all U.S. cow/calf operations in the 48 continental United States. Eighty-one percent of operations had commercial cattle... |

| A adoção da inseminação artificial em tempo fixo (IATF) é a biotecnologia aplicada à reprodução animal que mais aumentou em 10 anos, passando de 8%, em 2012, para 18%, em 2021. Em 2022, espera-se um aumento de mais de 20%. Com objetivo de salientar os principais fatores que influenciam no bom resultado dessa biotécnica, esta cartilha foi confeccionada para que o produtor pudesse entender e avaliar, dentro de sua realidade, a viabilidade do investimento nessa prática. Os pontos abordados e as fotos mostradas servem para compartilhar nossas experiências a fim de contribuir para uma adoção segura e satisfatória da técnica pelo produtor. |

| This study aimed to compare the pregnancy rate using the conventional artificial insemination (AI) or deep intracornual artificial insemination (DIAI), with low number of spermatozoa (4.0 million sperm) in 270 Nelore cows. The animals were divided in two groups (G: G1 (135 cows) conventional AI was performed (=semen deposition in the uterine body) and in G2 (135 cows) to DIAI, in ipsilateral horn where the dominant follicle in the ovary had previously been detected, by ultrasound examinations. For both the methods, a single artificial insemination was carried out after visual estrus observation, checked three times a day (morning, afternoon and evening). The pregnancy diagnosis after 45 days was conducted by ultrasound. Results showed a better pregnancy... |

| Artificial insemination mastery in red drum, Sciaenops ocellatus, requires a first experimental step wOOng at getting basic biological data. Regarding males, a relation between optical density of the solution (OD) measured by spectrophotometry and sperm concentration (SC) has been established : OD O,161*SC + 0,119. Mean sperm concentration measured is 4,36.10 10 spz.mL-1. This study shows an influence of the solution of dilution on spermatozoa motility and its evolution during short term preservation. As far as females are concemed, the follow-up of final maturation through the observation of samples taken during reguIar strippings, seems to he a good technique to limit overripening and spontaneous liheration of ovules. Some artificial insemination trials... |

| The artificial insemination industry provides breeding products and services for both dairy and beef cattle. Two-thirds of the industry is organized as producer-owned cooperatives. The industry has been so highly successful in meeting the needs of producers for a high-quality reliable product that the United States is the world's leading producer and exporter of bull semen. Yet, more bulls (and consequently more cooperatives) are available than are technically needed for genetic variation and breeding requirements. The result of such product proliferation is higher semen prices and excessive costs for inventory, distribution, and marketing. To maintain their prominent role in the industry, the 22 cooperatives need to consolidate to streamline the... |

| ABSTRACT: The aim of this study was to evaluate different times for timed artificial insemination (TAI) in buffalo submitted to a P4/E2/eCG-based protocol. In this study, 204 buffaloes were distributed into one of two groups (TAI56, n=103 and TAI64, n=101). At a random stage of the oestrous cycle (Day 0 = D0), in the morning (TAI56, a.m.) or afternoon (TAI64, p.m.), buffaloes received an intravaginal progesterone device (P4; 1.0 g) plus EB (2.0 mg i.m.). On D9 a.m. (TAI56) or p.m. (TAI64), the P4 was removed and buffaloes received PGF2a (0.53 mg i.m. sodium cloprostenol) and eCG (400 IU i.m.). On D10 a.m. (TAI56) or p.m. (TAI64), 24 h after P4 removal, buffaloes were treated with EB (1.0 mg i.m.). Buffaloes from TAI56 and TAI64 were inseminated 56 and 64 h... |

| The present study aimed to examine the possibility that bovine somatotropin (BST) treatment after artificial insemination (AI) may improve the fertility by the stimulation of corpus luteum (CL) function in seasonally anestrous ewes. The experiment was conducted at the Tawa Field Station, Shibecha-cho in Hokkaido, Japan, during the non-breeding season (May, 1995). Eighty-nine mature (2 to 3 years old) Suffolk and Suffolk-crossed ewes were treated with controlled internal drug release devices containing 0.3 g progesterone (CIDR-G) for 12 days. Ewes were injected intramuscularly with 500 IU PMSG the day before CIDR removal. Eighty-seven ewes were assigned to an insemination of frozen semen on a fixed-time basis (42 to 50 h) after removal of CIDR. On the 11th... |
