ABSTRACT
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)

This study evaluated the influence of the presence or absence of corpus luteum at the beginning ofartificial insemination protocol at fixed time (TAI) in pregnancy rate. 48 animals were used which prior toinsertion of releasing progesterone device were evaluated by rectal palpation for the presence or absence of thecorpus luteum, and divided into two groups: G1 cows with the presence of the corpus luteum, and G2 cows notwithout palpable structures. The data collected from individual records were tabulated in spreadsheets andevaluated in the SAS software (2000). The pregnancy rate for G1 and G2 was 40% 53.57% respectively, P >0.05. Suggesting that the presence of corpus luteum did not influence the pregnancy rate in TAI.(AU)

The aim of this study was to correlate the profile of insemination, uterine status and the presence ofmucus on the day of insemination, with a pregnancy rate of buffalo cows in lowland area in the state of Amapá.This study was conducted at Fazenda general Moto LTDA., 148 km from the town of Macapa. The animals werekept in extensive grazing system. They used 48 animals received the following protocol: Day 0 (D0) to insert theintravaginal device P4 and 2.0 mg BE. At D9 was taken withdrawal of the device and application of 0.5 mg ofPGF2a and 400 IU eCG. In D11 was applied 0.004 mg GRnH and carried out insemination in D12, 64 hoursafter the withdrawal. The diagnosis of pregnancy was performed 30 days after artificial insemination. The datacollected from individual records were tabulated in spreadsheets. And evaluated in the SAS software (2000) 23buffaloes that had a positive pregnancy, 3 a bad AI profile, 18 a good AI profile and 2 excellent AI profile. 25cows got negative pregnancy, among them 4 demonstrated bad AI profile, 21 a good AI profile and no possessedexcellent AI profile. Regarding uterine Status- 46 animals (97.9%) had contracted uterus, however only 22(47.83%) animals were diagnosed with positive penhez. The variable presence of mucus, of 48 buffalos 21(43.75%) had such characteristics. The pregnancy rate was 22.9% (11) for the cows with mucus during theIATF. The variables profile of AI, mucus, uterine status, no positive influence on the pregnancy rate.(AU)

The objective of this study was to evaluate if the progesterone device (P4) of 3rd use would be efficientto induce the cyclicity and consequent pregnancy rate in nelore heifers. We used 65 animals with a mean weightof 338 kg. All kept in the same environmental and handling conditions. The induction of estrus was performed in33 females with P4 implant of 3rd use, thus forming Group 1 (G1 = 33), those that did not receive the implantwere allocated in Group 2 (G2 = 32). Thirty-two days post-induction protocol was performed on all animals forTAI. The data collected were tabulated in electronic spreadsheets and evaluated in the SAS software (2010). TheTAI pregnancy rate was 21.21% (G1) (7/33) and 46.88% (15/32) for (G2) (P < 0.05). Thus suggesting that priorinduction to puberty with P4 device of 3rd use was not effective.(AU)
