ABSTRACT
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.(AU)

The reproductive planning a squad, using natural breeding (MN), can be carried out to the maximumuse of animals (Campos, 2008). However there are practical to provide improvements in the system, such asartificial insemination (AI). twelve were used sows with an average age of two years. Pregnancy diagnosis wasperformed 30 days after the procedure. The arrays were divided into two groups, six were subjected to the IA-six(MN). The pregnancy rate was 66.67% and the rate of return to estrus was 33.33% for both treatments (P>0.05), with no significant difference. The AI in pigs shows satisfactory results in the northeast of Pará, whichprovides the producer, recognize that the method is the most profitable because it reduces the number of animalsin the herd, reducing environmental impacts and risks of transmission of sexually transmitted diseases.(AU)

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.(AU)

The objective of this study was to evaluate the reproductive efficiency in a commercial farm pig in thecity of Benevides, Pará. We carried out the collection of pregnancy and parturition of the data arrays in twoperiods, and evaluated the rate of return to estrus. 90 arrays of March were accompanied to August 2015 and 81arrays from February to April 2016. Females were multiparous, housed in gestation crates and maternity andwithout food manejo difference. Thus, the feeding mothers in pregnancy and phase of breeding was carried outtwice a day (± 2 kg feed / animal / day). The pregnancy rate was 66.35% referring to 2015 and 57.92% relatedto 2016. Rates of return to estrus were 33.65% and 42.09% for 2015 and 2016, respectively. The reproductiverates of ownership are lower than ideal for productive activity.(AU)

The aim of the study was to evaluate the influence of follicular population (PF) in the TAI of D0 in thepregnancy rate of Nelore PO cows. 36 cows were used, divided into two groups (≤ 10 and> 10 follicles) weresubmitted to the following protocol. In the D0 was introduced intravaginal P4 implant (DIB® 1g; Zoetis) andapplied 2mL BE (Gonadiol®; Zoetis). In D8 was removed the implant and applied 300 IU (1.5 mL) of eCG(Novormon®; Zoetis) and 2.0 mL of PGF2a (Ciosin®, Zoetis). In the D9 was applied 1mL BE (Gonadiol®;Zoetis) and 24h after TAI was made. The cows were subjected to ultrasound examinations Transvaginal in D0 toPF score. Pregnancy diagnosis was performed 30 days after TAI. The data were analyzed by SAS software(2009) and the pregnancy rate was compared using the chi-square test (P < 0.05). The pregnancy rate for PF≤10 group was 54.55% and the PF group> 10 was 28.57% in the D0, with no statistical difference (P > 0.05).(AU)
