The present work has investigated the degeneration rate of goat primordial follicles in situ after preservation in PBS or TCM 199 at different temperatures and incubation times. For each animal the ovarian pair was divided into 19 fragments. One ovarian fragment was taken randomly and immediately fixed (control). The other 18 ovarian fragments were randomly distributed in tubes containing PBS or TCM 199 and stored at 4º, 20º or 39ºC for 4, 12 or 24h. The storage of ovarian fragments in PBS or TCM 199 at 20ºC for 12h and 24h or at 39ºC, in all incubation times tested, increased significantly the percentage of degenerated primordial follicles (P<0.05). In contrast, for both media tested the degeneration rate of primordial follicles preserved at 4ºC for up... |

Os resultados preliminares do Censo Agropecuário mostraram que o rebanho caprino no Brasil é menor do que apontavam estudos anteriores. Para compreender esse resultado é necessário, entre outros estudos, verificar a evolução do efetivo no período. O objetivo do presente trabalho foi mensurar a concentração do rebanho caprino no Brasil, nos anos de 1995/96 e 2006. Para tanto, utilizou-se a metodologia do índice T de Theil e da análise tabular dos dados. Os resultados demonstraram redução da concentração do rebanho entre as Unidades da Federação. Apesar de se verificar concentração do rebanho pela análise tabular, esta não foi fortemente caracterizada pelo índice T de Theil, que mensurou a distribuição do rebanho em relação à área das Unidades da Federação.... |

Os efeitos da suplementacao volumosa, durante o periodo critico e da mineralizacao mais vermifugacao, foram estudados em ovinos e caprinos, em um experimento realizado na Fazenda Periperi, Nordeste da Bahia, de junho de 1977 a maio de 1980. O trabalho envolveu 125 matrizes caprinas Sem Raca Definida (SRD) e igual numero de ovelhas Morada Nova, distribuidas, cada especie, em cinco grupos de 25 matrizes. Os Tratamentos foram: (1) Pastagem Nativa (PN); (2) Pastagem Nativa + Mineralizacao e Vermifugacao (PN+MV); (3) Tratamento 2 + suplementacao verde a base de capim napier e cana-de-acucar; (4) Tratamento 2 + feno de capim buffel; (5) Tratamento 2 + silagem de capim napier e cana-de-acucar. Os resultados demonstraram a incapacidade dos ovinos nao suplementados... |

Three experiments were carried out to determine the optimum selenium-vitamin E injection level to maintain acceptable blood selenium (Se) status of does and kids, as well as to determine the relation of that status to mortality rates in kids. In experiment 1, 238 goats were assigned to one of three groups during the mating period: A1-control, A2- 0.06mgSe+0.8IU vitE/kgBW and A3-0.125mgSe+1.7IU vitE/kgBW. No differences (P>.05) for fertility and prolificacy were observed among the groups. Blood Se concentration did not differ among Se-vit E groups and control group before injection, and both groups showed Se deficient condition. There was a trend (P<.05, 32%) to increase Se blood level 60 days post-treatment, but difference was not observed between A2... |

This study reported the effects of prostaglandin (PGF2a) administration 10 days apart on reproductive parameters of cyclic artificial inseminated (AI) nulliparous Alpine (n=9) and Saanen (n=9) goats. Animals received two doses of 22.5mg PGF2a 10 days apart. After 1st and 2nd PGF2a administrations, estrus was monitored at 12 h intervals, with a buck teaser. Plasma progesterone concentration (ng/mL) was determined from blood sampled on day 0 (1st PGF2a) and the following 5, 10 (2nd PGF2a), 15, 20, 25 and 30 days. After the onset of the second estrus, females were transrectally (5 MHz probe) scanned at 4 hour intervals until at least 8h after ovulation. Pregnancy was checked through transrectal ultrasound on days 20, 25, 30, 35 and 90 after insemination. All... |

ABSTRACT This study aimed to evaluate the buriti oil (Mauritia flexuosa L.) inclusion levels (0, 15, 30, and 45 g kg−1 in dry matter) replacing ground corn on the feeding behavior, as well as physiological and hematological variables of crossbred lactating Anglo Nubian goats. Eight Anglo Nubian goats were used, which were distributed in a double 4 × 4 Latin square experimental design (four periods and four levels of buriti oil) replacing corn in the total dry matter. For the evaluation of feeding behavior, single animals were observed every ten minutes for 24 h on three days. Respiratory rate (RR), heart rate (HR), rectal temperature (RT), and sweating rate (SR) of the animals were evaluated in the morning (09:00 h) and in the afternoon (15:00 h). Blood... |

The effects of feeding urea on embryo production, quality and developmental stages and follicular status at the beginning of a superovulatory treatment of Toggenburg does fed urea diet were investigated in this study. Eighteen females were randomly allocated to receive diets with: no urea (control, n=8), and 2.4% urea dietary dry matter (n=10) UDM. The embryo recovery was performed at day 7 or 8 of estrus cycle by transcervical technique and classified according to quality and developmental stage. The follicular status was determined by transrectal ultrasonography at the first day of FSH injection. The number and quality of embryos were not affected by dietary urea concentration. Embryos from does treated with 2.4% UDM were recovered at advanced stage.... |

It was used 4,313 weight records from birth to 196 days of age from 946 Anglo-nubiana breed goats, progenies from 43 sires and 279 dams, controlled in the period from 1980 to 2005, with the objective of estimating covariance functions and genetic parameters of animals by using random regression models. It was evaluated 12 random regression models, with degrees ranging from 1 to 7 for direct additive genetic and maternal and animal permanent environment effect and residual variance adjusted by using animal age ordinary polynomial of third order. Models were compared by using likelihood ratio test and by Bayesian information criterion of Schwarz and Akaike information criterion. The model selected based on Bayesian information criterion was the one that... |

Avaliaram-se as variáveis cinéticas da cefepime e a produção de leite de cabras após a administração parenteral (intravenosa e intramuscular) de cefepime, com e sem reação inflamatória na região implantada. Dez cabras em lactação, implantadas com caixas de material sem reação imunológica para colher o fluido de tecido (FT) foram usadas em dois experimentos. No primeiro a aplicação de cefepime foi feita na primeira semana após a implantação e no segundo na oitava semana. Na primeira semana após a implantação observou-se elevação dos níveis de proteína no fluido do tecido após uma simples dose de 20mg/kg de cefepime via endovenosa ou intramuscular. Amostras do sangue e do leite foram obtidas e as variáveis cinéticas foram avaliadas. |

The objective of this study was to present some factors affecting feed efficiency in dairy goats. To develop our work, individual and average data from performance experiments with lactating goats were used. The following variables were evaluated: gross feed efficiency, adjusted feed efficiency, dry matter intake, milk-yield, 3.5% fat-corrected milk yield, dry matter digestibility, dietary neutral detergent fiber content, different roughage-to-concentrate ratios and body weight. The statistical analyses involved the application of descriptive and dispersion measures besides Pearson's correlation coefficient and linear regression analysis. The analyzed variables were highly correlated with feed efficiency. The feed efficiency of lactating goats was affected... |
