Lactating Cows

The aim of this study was to evaluate effects of season and lactation status on embryo production in Holstein donors (n = 51). Data from 195 embryo collections (94 from lactating cows and 101 from non-lactating cows), at a dairy farm located in Descalvado, Sao Paulo, Brazil, in 2005, were analyzed. The superstimulation protocol included two 3-mg norgestomet ear implants (Crestar�; Intervet, Sao Paulo, Brazil) and an injection of 3 mg of estradiol benzoate IM (EB) on random days of the estrous cycle. Four days later, 500 IU FSH IM (Pluset�; Calier, Buenos Aires, Argentina) were divided into 8 decreasing doses given 12 h apart. With the seventh FSH injection, 0.530 mg IM of sodium cloprostenol (PGFα Ciosin�; Coopers-Brazil, Sao Paulo, Brazil) was given, and implants were removed with the eighth FSH injection. Twelve hours later, 250 �g IM of gonadorelin (Fertagyl�; Intervet) was given, followed by two AI 12 and 24 h later. Ova/embryos were recovered 6.5 days after the first insemination. The total number of ova/embryos, IETS grades 1, 2, and 3 (viable) and grade 4 plus unfertilized (non-viable), were analyzed by General Linear Model (GLM). Effects of donor, lactation status (lactating or non-lactating), sire, season (1: January through March, n = 56; 2: April through June, n = 37; 3: July through September, n = 50; 4: October through December, n = 52), and their interactions were included in the model. There was an effect of donor on all outcome variables (P < 0.01). There was an effect of season on the total number of ova/embryos (1: 10.2 � 1.2; 2: 6.6 � 1.0; 3: 10.0 � 1.1; 4: 11.2 � 1.2; P < 0.02) and of viable embryos (1: 3.7 � 0.5; 2: 2.4 � 0.5; 3: 5.9 � 0.9; 4: 4.4 � 0.7; P < 0.001). Lactation status influenced the total number of ova/embryos (lactating: 10.9 � 0.9 vs. non-lactating: 8.7 � 0.7; P < 0.001) and the number of non-viable embryos (lactating: 6.7 � 0.8 vs. non-lactating: 4.4 � 0.5; P < 0.01). However, there was no effect of lactation status on the number of viable embryos (lactating: 4.14 � 0.5 vs. non-lactating: 4.29 � 0.5; P > 0.10). In summary, the number of viable embryos in Holstein cows was influenced by season and donor, but not by lactation status.

Synchronization Protocol

The most important barrier to the increase of buffalo productivity is an overall poor reproductive efficiency, characterized by late sexual maturity, seasonal anestrus and long periods of postpartum ovarian inactivity resulting in extended calving intervals and poor expression of estrus behavior (Singh J et al., 2000, Anim. Reprod. Sci. 60–61, 593–604). Buffaloes are seasonal breeders with the highest reproductive activities during winter (short day lengths) and a high frequency of anestrus during the summer months (Singh G et al. 1985, Ind. J. Anim. Res. 19, 57–60). Recent research demonstrated that a combination of progesterone, estradiol benzoate and equine chorionic gonadotropin (eCG) was effective for estrus induction and synchronization in buffalo heifers under Mediterranean conditions (Barile et al. 2001, Livestock Prod. Sci. 68, 283–287). The aim of the present study was to investigate the impact of an estrus synchronization protocol on reproductive efficiency of water buffalo during out of the normal breeding season. A total of six heifers (21 to 23 months of age) and three cows (5, 6 and 18 years of age) were enrolled in an estrus synchronization protocol lasting for 12 days. All animals were kept under tropical conditions in the coastal part of Paraná (Antonina), about 450km south of São Paulo. The experiment was performed in December, 2002, during the Brazilian summer season, when reproductive efficiency of buffaloes is greatly reduced. On the first day of the protocol (Day 0), animals were implanted with an intravaginal device containing 1g of progesterone (DIB, Syntex SA, Buenos Aires, Argentina) and injected with 10mg estradiol benzoate (Estrogin, Famavet, São Paulo, Brazil). On Day 9, the DIB implant was removed and the animals received 150μg (i.m.) of cloprostenol (Prolise, Syntex SA, Buenos Aires, Argentina) and 2500 IU of eCG (Novormon, Syntex SA, Buenos Aires, Argentina). On Day 11, all animals received 1500 IU of hCG (Vetecor, Lab. Calier, Spain). Artificial insemination (AI) was performed on Day 12 using frozen-thawed semen from a bull of proven fertility. Only one AI was performed per heifer/cow. Pregnancies were determined by ultrasound examination at 53 days following AI and confirmed by rectal palpation at 90 days post AI. The use of this estrus synchronization protocol, followed by fixed-time insemination, resulted in four pregnant heifers (66%) and three pregnant cows (100%). Our results demonstrate that buffalo reproduction can be successful during out-of-breeding season when adequate hormonal treatment is used. Additional experiments should be done to validate the protocol.

The objective of this study was to evaluate the administration of the follicle-stimulating hormone (FSH-p) or equine chorionic gonadotropin (eCG) in protocols of ovulation synchronization. One hundred forty-nine crossbred Holstein-Gyr cows were used in 2 properties in Minas Gerais and 3 treatments: TControl (n = 49 cows), Day 0: insert of a progesterone device (Primer®, Tecnopec, São Paulo, Brazil) + 2 mg of estradiol benzoate (RIC-BE®); Day 8: removal of Primer + 112 mg of D-cloprostenol (Prolise®, ARSA SRL, Buenos Aires, Argentina) + 1 mg of estradiol benzoate and fixed-time artificial insemination (FTAI) accomplished 44 h after the removal of Primer; TFSH (n = 50 cows), similar to TControl, but on Day 8, 15 mg of FSH-p (Folltropin®, Bioniche Animal Health) was administered; TeCG (n = 50 cows), similar to TControl, with administration on Day 8 of 300 IU of eCG (Novormon®, Syntex SA, Buenos Aires, Argentina). Cows that returned to estrus 14 to 28 days after the FTAI were inseminated once again. For all statistical analysis, we used the program SAS 9.0 (2002; SAS Institute Inc., Cary, NC, USA) at 5% probability. Quantitative variables (live weight, days postpartum, follicular average per cow) were analyzed by variance, and body condition score by Friedman test. The pregnancy rates were submitted to logistic analysis considering the effect of local experimental factors and were analyzed by Spearman correlation among the variables studied and the pregnancy rate. There was no difference (P > 0.05) between treatment for pregnancy rate in FTAI protocols (TControl = 40.82%; TFSH = 38.00%; TeCG = 26.00%), in the first insemination after FTAI (TControl = 56.25%; TFSH = 70.59%; TeCG = 68.42%), and in FTAI plus first insemination after FTAI (TControl = 59.18%; TFSH =62.00%; TeCG = 52.00%), as well as for the estrus repetition (TControl = 55.17%; TFSH = 54.84%; TeCG = 51.35%) and the correlation (P > 0.05) among the pregnancy rate and postpartum period, milk production, body weight and body condition. No effect was observed on the pregnancy rate by the addition of the hormones FSH and eCG in the protocol of ovulation synchronization in crossbred Holstein-Gyr cows; however, reinsemination in the period from 14 to 28 days after FTAI increased the pregnancy rate.

Lactating Cows

The objective of this study was to evaluate the effect of reutilization of intravaginal progesterone devices on pregnancy rate of lactating and nonlactating Nelore cows submitted to fixed-time AI (FTAI). The study used 684 lactating cows (50 to 70 days postpartum) and 361 nonlactating cows (210 to 240 days postpartum). At random stages of the estrous cycle (Day 0), all animals received 2 mg of estradiol benzoate (Estrogin®, Farmavet, São Paulo, Brazil) and the animals of each category (lactating or nonlactating) were allocated in 1 of 2 treatments (new or used). Thus, the 4 groups consisted of lactating/new, lactating/used, nonlactating/new and nonlactating/used. The animals of lactating/new and nonlactating/new groups received a new intravaginal progesterone device (1 g of P4, DIB®, Intervet/Schering-Plough, São Paulo, Brazil) and the cows of lactating/used and nonlactating/used groups received a similar device that had previously been used for 8 days. At the time of P4 device removal (Day 8), the cows were treated with 150 μg of cloprostenol (Preloban®, Intervet/Schering-Plough), 1 mg of estradiol cypionate (ECP®, Pfizer, São Paulo, Brazil), and 300 IU of eCG (Folligon®, Intervet/Schering-Plough). The cows were FTAI on Day 10 (48 to 52 h after device removal). To evaluate the pregnancy rate, an ultrasonographic examination (CHISON 500VET, USP Brasil Eletromedicina, São Paulo, Brazil) was performed 30 days after the FTAI. Data were analyzed using the GENMOD procedure of SAS (SAS Institute, Cary, NC, USA).There was no interaction between treatment and BCS, AI bull, or technician. The pregnancy rates for the groups were 155/300 (51.7%a for lactating/new, 200/384 (52.1%a for lactating/used, 52/154 (33.8%b for nonlactating/new, and 96/207 (46.2%a for nonlactating/used (P = 0.0007). A reduction in pregnancy rate for nonlactating cows occurred when the intravaginal progesterone device was new. Although serum progesterone was not measured in the current trial, it is very likely that this finding might be explained by the high cyclicity rates in beef cows after weaning (210 days postpartum) and by the presence of CL producing additional support of progesterone besides the high P4 from the new device (Baruselli et al. 2004 Anim. Reprod. Sci. 82, 479-486). Many researchers found that greater circulating progesterone concentrations during progesterone implant treatment reduced LH pulsatility, LH follicular receptors, and follicular growth (Ireland and Roche, 1982 J. Reprod. Fertil. 64, 295-302). Furthermore, it seems likely that the presence of smaller-sized ovulatory follicles might contribute to ovulation failures, delayed ovulation, smaller CL area, and decrease in the pregnancy rate (Carvalho et al. 2008 Theriogenology 69, 167-175). In conclusion, lactating cows can be fixed-time inseminated using a new or a previously used DIB® as progesterone source. However, for nonlactating cows, a previously used device may increase pregnancy rates. USP Brasil Eletromedicina, ABS Pecplan and Fazendas Reunidas Rio Bravo.

The aim of the present experiment was to verify the correlation between follicular diameter and ovulation rate in Nellore cows submitted to LH treatment to add information to the limited literature about this subject. A preliminary test (experiment 1) was performed to determine the lowest dose of LH necessary to induce ovulation in follicles with diameter ≥10 mm. At a random stage of the estrous cycle (D0), Nellore cows (n = 20) received a progesterone intravaginal device (1.0 g, Primer®, Tecnopec, Sao Paulo, Brazil) and 2.5 mg of estradiol benzoate (EB, i.m., Estrogin®; Farmavet, Sao Paulo, Brazil). Eight days later (D8) PGF2α was administered (150 μg of D-cloprostenol, i.m., Prolise® ARSA S.R.L., Buenos Aires, Argentina) and the device was removed. Twenty-four hours after device removal, cows were treated with EB (1.0 mg, i.m.) and 48 h afterward; ovulation was determined by ultrasonography (US, Aloka 900, Tokyo, Japan). Three days after ovulation, the follicular growth was daily observed by US, and when the follicles reached ≥10 mm diameter, the cows were randomly allocated in 4 groups and treated with different doses of LH (i.m., Lutropin-V®, Bioniche, Ontario, Canada): Groups 1.56; 3.12; 6.25, and 12.5 mg. The data were analyzed by Fisher’s Exact Test (PROC FREQ, SAS). The ovulation rates were 0% (0/5), 80% (4/5), 80% (4/5), and 80% (4/5) respectively, and it was lower in group 1.56 when compared with the others (P < 0.02). Taking in account the results above, the dose of 6.25 mg to induce ovulation in Nellore cows (n = 58, experiment 2) submitted to the same protocol used in experiment 1 and randomly allocated in 5 groups according to follicular diameter at the time of LH administration: G1 (7.0–7.5 mm), G2 (7.6–8.0 mm), G3 (8.1–8.5 mm), G4 (8.6–9.0 mm), and G5 (9.1–10.0 mm). The results were analyzed by Logistic Regression (PROC GENMOD, SAS). The ovulation rates were 0% (0/11), 20% (2/10), 36% (4/11), 36% (4/11), and 90% (9/10), respectively, for G1, G2, G3, G4, and G5. When the data from 2 groups (except G5) were combined, G1 + G2 (7.0–8.0 mm), G3 + G4 (8.1–9.0 mm), and G5 (9.1–10.0) ovulation rates were, respectively, 9% (2/21), 36% (8/22), and 90% (9/10). There were significant differences when comparing G1 + G2 v. G5 (P < 0.01), G3 + G4 v. G5 (P < 0.02) and G1 + G2 v. G3 + G4 (P < 0.03). After LH application, the smallest follicle that ovulated had a diameter of 7.65 mm. In summary, although LH administration induced ovulation in one follicle of 7.65 mm, high ovulation rates were observed only when the follicles reached <9.0 mm. These data will be used to study the correlation between ovulation rate and expression of isoforms of LH mRNA receptors in theca and granulosa cells.

The Difference

In the present study, the superstimulatory protocol coined P-36 (Nogueira et al. 2007 Theriogenology 67, 655–660) was modified in order to test if replacement of pFSH by eCG in the last day of superstimulatory treatment would improve follicular growth, ovulation rate, and embryo yield. Nelore cows (n = 20) were randomly allocated to two groups: P-36/LH48 and P-36/LH48/eCG. Each female received both treatments in a cross-over design; the first experimental period was in October (Spring 2006, both groups) and the second in February (Summer 2007, both groups). At a random stage of the estrous cycle (D0), animals received a progesterone intravaginal device (DIB�, 1.0 g; Syntex S.A., Buenos Aires, Argentina) plus estradiol benzoate (EB, Estrogin�, 2.5 mg IM; Farmavet, Sao Paulo, Brazil). The animals were superstimulated with pFSH (Folltropin-V�, Bioniche Animal Health, Ontario, Canada), administered twice daily in decreasing doses of 53.2, 39.9, 26.6, and 13.3 mg (total dose = 133 mg), from Day 5 to Day 8, except the P-36/LH48/eCG group, where the last two doses of pFSH were replaced by two doses (200 IU) of eCG (Novormon�, Syntex, Buenos Aires, Argentina). All cows were treated with D-cloprostenol (150 µg IM;Veteglan�, Calier, Barcelona, Spain) on Day 7 at 7:00 h, and DIBs� were removed 36 h after PGF2alpha administration. On Day 9, ovulation was induced by pLH administration (Lutropin�, 12.5 mg IM; Bioniche Animal Health) at 7:00 h. The animals were inseminated at 12 and 24 h after pLH administration, without estrus detection. Embryos were recovered on Day 16 or 17. Data were analyzed by ANOVA (Proc Mixed, SAS; SAS Institute, Inc., Cary, NC, USA), and the difference was considered significant when P < 0.05 or not significant (NS). Results for animals from groups P-36/LH48 and P-36/LH48/eCG were compared and are reported in this order. The number of follicles with diameter larger than 6 mm at the time of pLH administration (15.25 � 2.06 and 21.05 � 2.76; P < 0.01), the ovulation rate observed up to 48 h after pLH administration (77.7 � 5.6 and 83.9 � 2.6; NS), the total number of oocytes/embryos recovered (6.65 � 1.18 and 10.0 � 1.48; P < 0.03), the number of embryos recovered (6.05 � 1.24 and 8.35 � 1.30; NS), and the number of viable embryos (5.10 � 1.10 and 7.30 � 1.20; NS) are reported. The embryo quality (excellent, good, fair, and poor) was NS among groups P-36/LH48 and P-36/LH48/eCG. It is concluded that replacement of pFSH by eCG, on the last day of the superstimulatory protocol P-36, was beneficial since there was a significant increase in the number of follicles (>6 mm at the time of pLH administration) and the total number of structures recovered. Experiments are in progress to confirm these beneficial effects of eCG on the P-36 protocol. This work was supported by FAPESP (Sao Paulo, Brazil). A. C. Z.

Resumo: O artigo que ora se apresenta é, na realidade, um pequeno ensaio que tem por finalidade indagar a importância da educação no pensamento de Søren Kierkegaard e investigar se, no âmbito da existência como possibilidade, uma educação voltada para a subjetividade se mostra efetiva diante dos debates acerca da liberdade e da singularidade do indivíduo. Pouco se debate sobre o conceito de educação em Kierkegaard, porém, acreditamos que se trata de um ponto basilar no pensamento do filósofo dinamarquês, conforme buscamos demonstrar, e deve ser objeto de maiores pesquisas, estudos e reflexões. Tomamos como referência para o início desse debate textos como as Migalhas Filosóficas e o Post-Scriptum, onde a subjetividade e a singularidade aparecem como conceitos fundamentais.Palavras-chave: Educação.

There is little debate about the concept of education in Kierkegaard, but we believe that this is a basic point in the thinking of the Danish philosopher, as we seek to demonstrate, and should be the object of further research, study and reflection. We take as reference for the beginning of this debate texts such as the Philosophical Fragments and the Post-Scriptum, where subjectivity and singularity appear as fundamental concepts.Keywords: Education.

Esse artigo analisa duas leituras distintas do Anel do Nibelungo, de Richard Wagner: o projeto denominado Colón-Ring, que terá lugar em Buenos Aires em 2012, e a encenação de A valquíria a cargo de André Heller-Lopes que ocupou o palco do Theatro Municipal de São Paulo em novembro de 2011. Meu objetivo consiste em explorar a dimensão filosófica da obra wagneriana, mostrando como o libretto do Anel pode ser interpretado a partir de uma postura crítica em relação à Modernidade que ocupou diferentes pensadores desde a segunda metade do século XVIII, especialmente no contexto da estética alemã. Segundo meu ponto de vista, é essa compreensão, em última análise, que orienta a montagem de Heller Lopes.

Centrado na apreensão das conexões empíricas e das inter-relações analíticas entre produção cultural, cidade e gênero, o artigo visa um tríplice objetivo: mapear alguns dos modelos teóricos utilizados na análise e interpretação desses fenômenos; discutir uma bibliografia específica sobre cidade, linguagem artística e experiência social; analisar o entrelaçamento dessas dimensões na cidade de São Paulo, nos anos de 1940 a 1960, com foco na dramaturgia e com o auxílio de exemplos retirados de Florença, Paris e Buenos Aires. Entendendo as cidades como arenas culturais, como “lugar de germinação, de experimentos e de combate cultural” (Morse), o artigo partilha a ideia de que “as cidades e suas representações se produzem mutuamente” (Gorelik), e defende o argumento de que determinadas manifestações culturais só acontecem em cidades específicas em função das condições sociais, do potencial e dos constrangimentos que enredam a criação, a autoria, a linguagem e as relações de gênero.
