Adoption and Profitability of Breeding Technologies on United States Dairy Farms AgEcon
Khanal, Aditya R.; Gillespie, Jeffrey M..
Adoption decisions and profitability of advanced breeding technologies are analyzed for U.S. dairy farms. The bivariate probit with selection model is used. Results show that specialized, younger, more educated farmers with longer planning horizons are more likely to adopt the technologies, with positive impacts on profitability and negative influences on cost of production.

Assessing the Value of Coordinated Sire Genetics in a Synchronized AI Program AgEcon
Parcell, Joseph L.; Schaefer, Daniel; Patterson, David J.; John, Mike; Kerley, Monty S.; Haden, Kent.
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.

Avaliação de ciclo de vida de sistemas modais e melhorados de cria no Pantanal. Infoteca-e
DIAS, F. R. T.; NOGUEIRA, E.; SILVA, J. C. B..
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...

Avaliação do sêmen refrigerado bovino durante quinze dias, comparando três diluidores comerciais. Infoteca-e
CAVALCANTI, P. R.; MOTTI, A. C. L.; REIS, W. V. A. dos; SILVA, L. G. da; NICACIO, A. C.; DIAS, F. R. T.; NOGUEIRA, E.; SILVA, J. C. B..
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...

Body condition score to predict the postpartum fertility of crossbred beef cows PAB
Moraes,José Carlos Ferrugem; Jaume,Carlos Miguel; Souza,Carlos José Hoff de.
The relationship between changes in body condition score (BCS) during the postpartum and fertility in beef cows suckling calves under extensive conditions were investigated. Cows were subjected to four BCS evaluations over the postpartum period, starting around one month after calving. In the second evaluation cows were treated with medroxy-progesterone acetate impregnated pessaries and received an injection of estradiol benzoate. At the third evaluation, pessaries were removed and calves were separated from the cows for 96 hours, during which time estrous was observed twice a day, and animals artificially inseminated 12 hours after detection. When calves returned to their dams, bulls were introduced until a 60-day mating period was reached. The...

Comparison between deep intracornual artificial insemination (dIAI) and conventional artificial insemination (AI) using low concentration of spermatozoa in beef cattle BABT
Meirelles,Ciro; Kozicki,Luiz Ernandes; Weiss,Romildo Romualdo; Segui,Marcio Saporski; Souza,Antonio; Santos,Ivo Walter dos; Breda,Jose Carlos dos Santos.
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...

Compte rendu des premières expérimentations de fécondation artificielle chez l'ombrine, Sciaenops ocellatus : études préliminaires de la maturation finale des ovocytes et de la qualité du sperme ArchiMer
Gardes, Lionel; Buchet, Vincent; Villanove, Philippe; Fauvel, Christian.
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...

Cooperatives' Role in the Artificial Insemination Industry AgEcon
Hogeland, Julie A..
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...

Different times to perform timed artificial insemination when using a P4/E2/eCG-based protocol in buffalo Ciência Rural
Carvalho,Nelcio Antonio Tonizza de; Carvalho,Júlia Gleyci Soares de; Sales,José Nélio de Sousa; Macari,Rodrigo Caron; Baruselli,Pietro Sampaio.
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...

Effect of Bovine Somatotropin Administration on Day 11 after Artificial Insemination in Estrus-Induced Ewes during the Non-Breeding Season OAK
Fukui, Yutaka; Yamamura, Kunio; Matsunaga, Nobuyoshi; Miyamoto, Akio; 福井, 豊; 宮本, 明夫.
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...

Effect of estrus synchronization and artificial insemination on reproductive performance of Merino sheep Braz. J. Vet. Res. Anim. Sci.
Simonetti,Laura; Ramos,Guillermo; Gardón,Juan Carlos.
The experiment was conducted to determine the reproductive performance (lambing rate and litter size) of sheep artificially inseminated at a synchronized estrus in relation to rams, dose of PMSG and number of artificial inseminations performed. During spring cyclic Merino adult ewes were treated with intravaginal sponges impregnated with 60 mg medroxyprogesterone acetate (MAP). After 14 days sponges were removed and the females received an intramuscular injection of either 375 or 400 IU pregnant mare serum gonadotropin (PMSG). Estrus detection was performed with vasectomized rams. Females in estrus were cervically inseminated with fresh diluted semen from different rams either once or twice. Data on lambing rate and litter size were recorded. Lambing rate...

Factors Affecting the Fertility of Ewes after Intrauterine Insemination with Frozen-Thawed Semen During the Non-Breeding Season OAK
FUKUI, Yutaka; KOHNO, Hirohide; OKABE, Kentaro; KATSUKI, Sara; YOSHIZAWA, Masahiro; TOGARI, Tetsuro; WATANABE, Hiroyuki; 福井, 豊.
In this study, two successive field trials were conducted during the non-breeding season to investigate various factors affecting on fertility of Suffolk ewes after intrauterine insemination with frozen-thawed semen. In the first year (Experiment 1), three sperm numbers per insemination dose (0.25, 0.5 and 1 million sperm) and five sheep farms were used, and in the second year (Experiment 2), parity, age, body weight, body condition score (BCS) and postpartum days were investigated to compare pregnancy and lambing rates. High pregnancy and lambing rates (70.6 and 70.6%, respectively) were obtained with 0.25 million sperm per dose. There were no significant differences in the pregnancy and lambing rates among the five farms, but there was a tendency for one...
