Número de leitões nascidos vivos e taxa de mortalidade ao nascimento de leitões oriundos de granja comercial localizada no nordeste paraense / Number of live born piglets and mortality rate at birth of piglets coming from commercial farm located in the northeast Pará

The work aims to provide knowledge of the actual production of a commercial farm, showing itspotential according to the reproductive management adopted. The work was conducted on a property located onHighway Augusto Meira Filho. - Km 2, in the city of Benevides, Northeastern Pará Females were multiparous,covered by natural mating. The study included the collection of farrowing matrix data in two distinct periods.They analyzed the mortality rate at birth and the number of piglets born alive. It followed 90 mothers in theperiod from March to August 2015 and 81 mothers in the period from February to April 2016. The data wereorganized in spreadsheets in Excel throughout the monitoring period. This study was the 8.63 value of pigletsborn alive according to the data for the year 2015 and 8.30 piglets born alive during follow-up in 2016. Thebirth mortality rate was 10.57% and 7.32% for the years 2015 and 2016, respectively. The reproductive indexobserved on the property is within the reproductive parameters of pig activity. The number of piglets born perlitter is well below, as evidenced by the literature.

Taxa de prenhez em matrizes suínas submetidas ao método de Inseminação Artificial Intracervical e Inseminação Artificial Intrauterina em granja comercial no nordeste paraense / Pregnancy rate in sows submitted to the method of Insemination intracervical Artificial Insemination Intrauterine Artificial and in commercial farm

The Artificial Insemination is a practice that provide significant improvements for breeding due to thedecrease of animals and maintenance of the reproductive indices, meaning lifting financial production returns. Thesix arrays used in this study were the breeds Large white, Duroc and crossbred with an average age of two years.Was performed lumbar pressure test determined the optimal time to perform the insemination. The players werepreviously evaluated and insemination dose was 50 ml, with two inseminations, with 12 hours. It used the spiralpipette Artificial Insemination intracervical (IAIC) and disposable pipette cap with the aid of IntrauterineInsemination catheter for intrauterine Artificial (IAIU), each model according insemination method, three arrays ineach method. The pregnancy rate was 66.67% and the rate of return to estrus was 33.33% for the two methods (P<0.05), so there was no significant statistical difference between the methods of Artificial Insemination.
