Última Application of a precision nutrition tool for growing and finishing pigs R. Bras. Zootec. Lovato,Gustavo Dias; Vale,Marcos Martinez do; Oliveira,Vladimir de; Klein,Daniela Regina; Branco,Tatiane. ABSTRACT The objective of this study was to evaluate a growth model applied to adjust nutritional programs for growing and finishing pigs, in a commercial production context. The phase I (calibration) was conducted in a commercial pig production unit. The data were collected from a nutritional program, a feed program, and an animal profile. In experimental phase II, these data were entered in the InraPorc® model for simulations and to propose adjustments to the commercial nutritional program. Afterwards, the conventional nutritional program (CNP) and the adjusted nutritional program (ANP) were compared with InraPorc® simulation. Animal profile was collected by weighing 30% of pigs per stall and monitoring their feed intake in each stage. Four hundred and...

Zootec. Peixoto,Jane de Oliveira; Faria,Danielle Assis de; Silva,Priscila Vendramini; Fonseca,Isabela; Lopes,Paulo Sávio; Guimarães,Simone Eliza Facioni. It was investigated the association between leptin gene single nucleotide polymorphisms (SNPs) T2411C and T3266G with carcass traits in F2 pigs obtained by crossing native Brazilian Piau with commercial sows composed of Landrace, Large White and Pietrain breeds. Association analyses were performed using a statistical model that included genotype, sex, and batch as fixed effects, sire and error as random effects. The T2411C SNP was associated with skinless and fatless boston shoulder weight (BSW), backfat thickness at last rib, 6.5 cm from the midline (P2), skinless and fatless picnic shoulder weight, and sirloin weight (SLW). The T3266G mutation was associated with slaughter age, bacon weight, BSW, midline backfat thickness between last and last but one...

Carmo,Fausto Moreira da Silva; Guimarães,Simone Eliza Facioni; Lopes,Paulo Sávio; Pires,Aldrin Vieira; Guimarães,Marta Fonseca Martins; Silva,Marcos Vinícius Gualberto Barbosa da; Schierholt,Alex Sandro; Silva,Kleibe de Moraes e; Gomide,Lúcio Alberto de Miranda. We studied the phenotypic effects of polymorphisms at the MYF5 gene in a divergent F2 swine population and found that one polymorphism was due to an insertion and another to a deletion. The genotypes of 359 F2 animals were obtained and the Normal/Normal (NN) and Normal/Insertion (NI) genotypes analyzed to determine associations with phenotypic data for performance, carcass and meat quality traits. Significant differences were observed (p < 0.05) between NN and NI animals for drip (NN = 3.14 ± 1.56; NI = 3.69 ± 2.78%), cooking (NN = 32.26 ± 2.41; NI = 33.21 ± 2.31%) and total loss (NN = 34.16 ± 2.63 and NI = 34.97 ± 2.08%). The Deletion marker was not statistically tested. The results indicate that the allelic variant Insertion is associated with a...

Paixão,Gustavo; Esteves,Alexandra; Payan-Carreira,Rita. ABSTRACT This study aimed to characterize the current production system of the Bísaro pig breed. Between February and April 2017, 194 questionnaires covering different aspects of the system were sent as a disclosed identity mail survey. A response rate of 31.4% was obtained. The typical Bísaro farmer is 46 years old, male, has five years of experience rearing pigs, and has a secondary or higher education degree. Piglets represented the majority of animals sold for slaughter (91.1%) and constituted 41.1% of total Bísaro meat produced with 343 tons. The majority of producers differentiate feed per production group (79.3%) and allow grazing (73.7%). Feeding is usually complemented with own-farm crops (94.7%). Traditional housing system remains the most common... Tipo: Info:eu-repo/semantics/article Palavras-chave: Livestock; Native breed; Pig production; Production system; Swine.

Bras. Zootec. Oliveira,Geyssane Farias de; Caldara,Fabiana Ribeiro; Garcia,Rodrigo Garófallo; Seno,Leonardo de Oliveira; Marcon,Ádila Vasconcelos; Foppa,Luciana; Martins,Renata Aparecida; Crone,Carla. ABSTRACT The objective of this work was to study the behavior of swine females in the grower phase using different observation intervals (continuous, 5, and 10 min). A total of 42 swine were used, 14 of them for each treatment, which were identified with a marker stick. These animals were observed using the focal sampling method for 5 h. The treatments were the observation intervals: continuous, every 5 min, and every 10 min. Among the behaviors analyzed during the experiment, the different observation intervals did not affect the estimated time spent in the activities. Time observation intervals of 10 min or less adequately describe the duration of the main behavioral parameters of female pigs in this setting.

Miranda-Furtado,Cristiana Libardi; Silva,Priscila Vendramini; Guimarães,Marta Fonseca Martins; Serão,Nicola Vergara Lopes; Guimarães,José Domingos; Guimarães,Simone Eliza Facioni. The main purpose of the present study was to identify for candidate genes related to ovulation in swines. To do so, it was investigated in ovarian follicular cells through quantitative real-time PCR the differential expression of the following genes: steroidogenic acute regulator (STAR), GATA-binding protein 4 (GATA), prostaglandin F2α (PGF2α), progesterone receptor (P4R), follicle-stimulating hormone receptor (FSHR), and cytochrome P450 aromatase (CYP19). These genes encode hormone receptors (FSHR and P4R), hormone (PGF2α), steroidogenic proteins (STAR and CYP19) and transcription factor (GATA). Folicular cells were collected from sows with high and low number of piglets/litters during the follicular phase of the estrus cycle. There was difference in...

Agricultural production is among the riskiest production activities. Similarly to other branches of agriculture in animal breeding the finished product is the result of complex procedures. The biological-technological procedure, the creation of the product is affected by an outstanding number of environmental factors which also cause uncertainties. In the North Great Plain Region of Hungary, sows, gilts and slaughter pigs are produced on a corporate farm. The reliable operation data of this company provide a stable basis for and estimating future costs and revenue and their distributions. Monte Carlo methods are one of the generally accepted tools for modeling risks. The significant independent variables, their ranges and probability distributions, and the...

Zotti,Everson; Resmini,Fábio Arnhold; Schutz,Luis Gustavo; Volz,Nilson; Milani,Raul Pelissari; Bridi,Ana Maria; Alfieri,Amauri Alcindo; Silva,Caio Abércio da. ABSTRACT A total of 5502 piglets from 435 sows were selected for evaluation of the effect of piglet birthweight and sow parity on mortality rate (MR), growth performance, and carcass traits in pigs. Piglets were distributed into one of eight categories according to their weight (<600, 601-800, 801-1000, 1001-1200, 1201-1400, 1401-1600, 1601-1800, and >1801 g) and sows were classified according to parity (1-5). The maximum MR during lactation (day 0 to day 21) was found in category <600 g, whereas the lowest was observed in categories ≥1401 g. Pigs with greater body weight (BW) at birth were equivalently greater until 59 days of age. Average daily weight gain (ADG) was improved by increasing piglet birthweight between 0 and 21 days as indicated by...

The objective of this work was to determine the maintenance requirement and the deposition efficiency of lysine in growing pigs. It was used the incomplete changeover experimental design, with replicates over time. Twelve castrated pigs with average body weight (BW) of 52±2 kg were kept in metabolism crates with a controlled temperature of 22ºC. The diets were formulated to supply 30, 50, 60, and 70% of the expected requirements of standardized lysine, and provided at 2.6 times the energy requirements for maintenance. The trial lasted 24 days and was divided into two periods of 12 days: seven days for animal adaptation to the diet and five days for sample collection. The increasing content of lysine in the diet did not affect dry matter intake of the pigs....

Mol. Biol. Silva,Kleibe de Moraes; Paixão,Débora Martins; Silva,Priscila Vendramini; Solero,Bruna Pena; Pereira,Mario Sérgio; Lopes,Paulo Sávio; Guimarães,Simone Eliza Facioni. The objective was to map QTL on porcine chromosome 4 and to associate them with carcass and internal organ traits in an F2 population. The F1 population was produced by outbreed crossing, using two native Brazilian breed Piau boars and 18 commercial sows. A total of 617 F2 animals issued from 11 F1 boars and 54 F1 sows were typed for a total of five microsatellite markers. The data were analyzed by multiple regressions developed for the analysis of crosses between outbred lines, using the QTL Express software. Significant evidence for QTL was found for pig chromosome 4 regarding carcass and internal organ traits. All QTL were detected in the same region of the chromosome, designated FAT1.

This study examines the effect of banning antimicrobial growth promoters on efficiency in the production of weaned and slaughter (finishing) pigs. We focus on the reaction of producers and production efficiency. We evaluate the estimated output and input shadow prices relative to market prices to analyse producer reactions and capture the impact on production efficiency by evaluating the effects of the ban changes on total factor productivity. To this end we model a multi product shadow profit function and incorporate output and input related shadow prices by using a second order flexible functional form. The development in total factor productivity is subsequently measured by calculating the Malmquist index on the farm level. To make infer-ences on the...

Paixão,Débora M.; Silva Filho,Miguel I. da; Pereira,Mário S.; Lopes,Marcos S.; Barbosa,Leandro; Souza,Katiene Régia Silva; Lopes,Paulo S.; Guimarães,Simone E.F.. The objective of this study was to map quantitative trait loci (QTL) on porcine chromosomes 16, 17 and 18 and to determine their association with carcass, organ and meat quality traits. An F2 population was produced by crossing two boars of the naturalized Brazilian Piau breed with 18 commercial females (Landrace x Large White x Pietrain). The population was genotyped for 11 microsatellite markers distributed over the three chromosomes and the results were used to construct a marker-specific linkage map for the population. Analysis of the polymorphic information content showed that the microsatellite markers were adequate for the study of quantitative traits. QTL were identified by regression interval mapping using QTL Express software. QTL not previously...

We apply a formal theoretical model of adaptation to two empirical settings within the agri-food industry: specialized pig production and food safety in Denmark. The objective is to allocate decision rights ex ante so that actual decisions taken ex post will optimize the profit accruing to the two parties in a contractual or integrative relation. Two applications are presented in this paper: First an actual partnership between two pork producers in Denmark. Based on detailed budgets we develop detailed schedules for the “reneging temptations” of the two partners- These are the temptations to renege on the contract during the evolution of the partnership. Using a model developed by Baker, Gibbons and Murphy (2006) we calculate equilibria using the Folk...

M. Dos; Caldara,Fabiana R.; Santos,Rodrigo C.. ABSTRACT The global animal production is increasing as expected to meet world demand for food, especially for meat products. This research aimed to investigate the effect of two types of roofs (clay and fiber-cement tiles) in a tropical area on the thermal comfort of farrowing sows and piglets. Twelve sows and forty-eight piglets were observed during summer in the Southeast region of Brazil. Climate variables, thermal comfort and surface temperature (sows and piglets) were assessed. The type of roofs clearly affected the piglets' surface temperature during all studied periods, but the results were not similar in the sows' surface temperature. Temperature and humidity index found was high in the building with fiber-cement tiles. The pen location in the...

In this paper, the demand for animal welfare attributes when buying pork fillet is investigated among Swedish respondents. More specifically, the coefficients of an indirect utility function and willingness to pay for animal welfare attributes are estimated. The utility function is estimated using a multinomial logit and a random parameter logit model. A realistic scenario when modeling consumer choices is to allow for heterogeneity in preferences. The random parameter logit model departs from the well known IIA property and allows for a more flexible taste distribution across individuals. The need for assuming randomness of some parameters are evaluated by using a specification testing procedure with artificial variables developed by McFadden and Train...
