The study aimed to evaluate the rates of visual oestrous and conception in Saanen goats subjected to oestrus synchronization at two seasons of the year. Hormonal synchronization was done using an intravaginal sponge impregnated with medroxyprogesterone acetate (MAP), for 11 days. In addition, 48 hours before sponge removal, 300 IU equine chorionic gonadotropin (eCG) and 125 µg cloprostenol were administered. The goats that showed heat were mounted by fertile males. The pregnancy diagnosis was done 60 days after the service by transrectal ultrasound. The rate of presentation of heat was 86.7 and 96.7% for the anoestrous season (January-February) and the cyclicity season (March-April), respectively, without significant difference between periods. The conception rate was 88.5 and 62.1% for the periods January-February and March-April, respectively (p<0.05). It is concluded that the use ...

Reproductive records (n=6350) of a dairy herd between 2000 and the first semester of 2016 were used based on the reproductive indices of the herd, considering the number of services per pregnancy, open days, pregnancy rate and occurrence of abortions. In total, 58 Holstein cows selected at random were genotyped to determine the presence of reproductive haplotypes (HH) that affect the reproductive performance of cows causing abortions. It was determined that 5.2% of the cows were carriers for HH1, 5.2% for HH3 and 3.4% for HH5, not finding carrier animals for the HH2 and HH4 haplotypes. Besides, 75% of the carrier cows (6/8) presented abortions not associated with the haplotype, except for one event whose reproducer was a carrier for HH3. Likewise, 54% of the non-carrier cows presented abortion events (27/50), not establishing a direct effect of the haplotype on the occurrence of abortion...

The dialectic of the tribute or contradiction in its abstract essence, could be formulated as follows: the tax presupposes private property, because only the owner may be taxed as real estate, personal property or of indefinite assets expressed in paper money is that the subject of "taxable event" but at the same time, it puts into question (and of course, limits and cuts in practice) the very core of private property, through which the institution of the tax exists and may continue exist. This reflection, developed at the philosophical level, we can perceive that the institution called the tribute is also of interest to those who move in this complex area. In our country, the Consolidated Text of the Tax Code, approved by Supreme Decree N º 135-99-EF (published on August 19 of 1,999) chose the tripartite classification for purposes of developing the concept of species tax is so, accord...

The aim of this study was to evaluate the efficiency of artificial insemination (AI) services in Holstein x Brahman cows under a heat induction programme. Three experiments were carried out. In Exp. 1, a retrospective analysis of the efficiency of AI insemination of 41 000 cows treated with the combination of progesterone and oestradiol benzoate or equine chorionic gonadotropin (eCG) was carried out. In Exp. 2 it was evaluated 863 cows inseminated after heat induced with progesterone and oestradiol benzoate to know the physiological events that occur before and after service in herds with a high incidence of anoestrus. Gynaecological examinations and determination of progesterone in milk were performed. The purpose of Exp. 3 was to improve the effectiveness of AI services for cows in postpartum anoestrus treated with progesterone and oestradiol benzoate combined with a technique to iden...

The aim of this study was to evaluate the productive and reproductive performance of cows submitted to an induced lactation protocol in a commercial dairy farm in Lima, Perú between 2015 and 2017. A total of 98 records of complete induced lactation and 191 records of normal lactations, both primiparous and multiparous were studied. Total production, corrected production and lactation length, as well as the conception rate and the number of services per conception were evaluated. The average total and corrected milk production were 7546 and 6641 kg, respectively, and 367 days of lactation length for induced lactation cows, while for normal lactating cows, values of 10129.8 kg, 8432.1 kg and 408.9 days were obtained, respectively (p<0.05). Likewise, induced lactation cows obtained 58% of pregnancy with 3.9 services/conception compared to control cows with 72.3% (p<0.05) and 3.6 serv...

Private investments depend on a set of variables, including country risk and interest rate. The degree of sensitivity will also depend on how the financial market is organized, which in many cases, such as the Peruvian, has oligopolistic characteristics. In a way, this may generate a series of distortions in the degree of interest rates influence on productive investments.According to the theoretical conception, interest rate depends on the type of monetary policy implemented by the central banks, if it is expansive it must fall, achieving an opposite effect if the position is restrictive. The evidence indicates that the degree of correlation between the primary issue and the interest rate is weak and positive, so that the effects that the monetary authority can achieve is minimal with respect to investments. The opposite is true of the monetary rate that exerts a high influence on inter...

Las inversiones privadas dependen de un conjunto de variables, entre las que están, el riesgo país y la tasa de interés; el grado de sensibilidad además dependerá de cómo se organice el mercado financiero, que en muchos casos, como el peruano presenta características oligopólicas, que en cierta forma generan un serie de distorsiones en el grado de influencia de las tasas de interés en las inversiones productivas. Según la concepción teórica, la tasa de interés depende del tipo de política monetaria que ejecuten los bancos centrales, si esta es expansiva esta debe de caer, logrando un efecto contrario si la posición es restrictiva. Las evidencias señalan que el grado de correlación entre la emisión primaria y la tasa de interés es débil y positiva, por lo que los efectos que pueda lograr la autoridad monetaria es mínima con respecto a las inversiones.

The emergence of a new category of assets linked to the experience of the systematic and massive violations of human rights, is one of the unexpected consequences of the implementation of the strategy of state terrorism in Chile. These physical marks of the last military dictatorship (1973-1990), have been expressed in the descriptions of atrocity or horror with which recount process and socially, we argue that for that to be possible, it was necessary to make themselves three key processes. First, the finding of extreme experience representing Nazi extermination policy and universal value, two, as a direct effect of the above, the creation of a human rights culture of a planetary, and three, the expansion of the traditional conception of cultural heritage. Only the combination of these three phenomena, it is possible today to identify sites of memory as a set of assets.

The forcefulness of the facts has shown an unquestionable truth: the life on Earth is sustained by a limited quantity of energy that is produced by organisms like the green plants. It is urgent to put into practice measures that assure the maintenance of at least such a quantity of energy. The growing deforestation rate and contamination (pollution), as by-products of the “modernity”, allows us to watch the seriously committed humanity’s future, not being necessary to wait to the generation of our children to appreciate their negative effects. In the beginning of the XXI century we already live them and inclusive we can even quantify them. It will be necessary to decide what to make in order to avoid one of the biggest ecological disasters: the asphyxia of the planet. The only formulas that can to avoid this outcome lie within the concept of Eco-Development or Sustainable Developme...

Intelligence is a construct of notable impact in our sociocultural context, related to a wide range of conceptual and operational definitions which originate positions that highlights cognitive and abstract elements and emotional and social skills, as well was perspectives that are focused on processes underlying the intelligent performance, such as in the case of executive functions (EFs), which are configured as cognitive processes that make it possible the self-regulation (Miyake & Friedman, 2012). Similarly, there are approaches that give intelligence a relevant and predictive role of school performance, an aspect strengthened by the psychometric perspective, where the concept of intelligence has been closely linked to learning. In this line, we also find the classical perspective of crystallized Intelligence of Cattell (1943), which refers to the knowledge acquired through educa...
