| O termo qualidade é definido pela International Organization of Standardization (ISO) como: ?totalidade de aspectos e características de um produto que leve sua habilidade em satisfazer uma necessidade anunciada ou implícita??. Esta definição deixa evidente a relação existente entre a escolha e a satisfação, onde a primeira é a tentativa direta de alcance da segunda. A qualidade da carne suína engloba diferentes enfoques por parte das indústrias e dos consumidores. As indústrias utilizam como parâmetros a porcentagem de carne magra, rendimento de cortes, necessidade mínima de acabamento, aparência atrativa e alta estabilidade durante a estocagem a frio. Os consumidores, além do aspecto nutricional, percebem como relevantes os aspectos sensoriais, os quais... |

| A total of 50 barrows were used to evaluate qualitative feed restriction on digestibility of dietary components, weight of organs of digestive tract, and composition and production of feces. Five experimental diets, with increasing levels of qualitative feed restriction of 0, 5, 10, 15, and 20% were used. There was linear reduction (P<0.001) of all digestibility coefficients on the levels of qualitative feed restriction, except for acid detergent fiber, which presented a quadratic response (P<0.05). Contents of total solids (P<0.01), volatile solids (P<0.05), and total minerals (P<0.001) in the feces augmented with increasing levels of qualitative feed restriction, whereas the levels of K (P<0.05), Cu (P<0.01), N, P, Na, Ca, Mg, Fe,... |

| The β-adrenergic agonist ractopamine is increasingly used in the swine industry due to higher consumer demand for leaner pork products. Redirecting nutrients to favor leanness rather than fat deposition, ractopamine improves growth and carcass traits of finishing pigs. However, the impact of this agonist on pork quality is not clearly defined. Understanding the biological effects of dietary ractopamine dose, treatment period, lysine levels, and the lysine to metabolizable energy ratio will help pork producers achieve improvements in animal performance, carcass leanness, and economic efficiency in swine production systems. |

| This study reports the use of the fluorescent in situ hybridization (FISH) with Sal3 probe for Salmonella detection in swine carcasses inner surface (swab); and in the correspondent samples of ileum, ileocolic, and mandibular lymph nodes; and tonsils, after dilution (1:10) in buffered peptone water and a pre-enrichment step (37(0)C, 18h). In order to evaluate the efficiency of FISH, 235 naturally contaminated samples were simultaneously tested by the cultural method (ISO 6579) and by the Vitek Immuno Diagnostic Assay System (VIDAS®) - Salmonella (SLM) system. The cultural method identified 39 positive samples. From these, VIDAS®- SLM only detected 23. FISH identified 115 positive samples. This difference was highly significant (P<0.001). From positive... |

| The objective of this study was to evaluate the reproductive performance of sows artificially inseminated by the intrauterine (IAIU) technique. The experiment was arranged in a randomized complete block design, with 300 sows being distributed in five insemination techniques: control, intra-cervical (IAIC) with 3x10(9) spermatozoa/100 mL; intrauterine (IAIU) with 1x10(9) spermatozoa/100 mL; intrauterine with com 1x10(9) spermatozoa/50 mL; intrauterine with 5x10(8) spermatozoa/100 mL; and intrauterine com 5x10(8) spermatozoa/50 mL. The sows submitted to intrauterine insemination presented a farrowing rate of 90.8% and return to estrus rate of 9.2%, which did not differ from the rates obtained by the intra-cervical technique (90.0% and 10.0%, respectively).... |

| Much of the increase use of vertical coordination in the U.S. swine industry has taken place through contract production. While the incidence of contracting is much higher in nontraditional hog production areas, a growing number of Midwestern producers are being faced with contract options. A variety of contractual arrangements are available through feed companies, integrators, genetics firms, and packers. However, little is known about the profitability and risk characteristics of these alternatives. This research suggests that risk neutral producers in the Midwest would prefer independent production, and risk averse producers would prefer to choose among the various types of coordination arrangements. |

| The aim of this research was to determine the effects of different factors of production (farm management strategy, veterinary management, physical farm conditions, and breeding technology) on the performance of Hungarian pig breeding farms. Performance is defined in a broad sense, reflecting the complexity of pig breeding, taking into consideration technological and economic indices. According to our hypothesis a direct, quantifiable stochastic relation can be shown between management strategy, veterinary practice management, construction and building engineering characteristics of plants, breeding technology and the performance of farms. The data for the analysis were acquired by a direct question survey of more than 130 Hungarian pig breeding farms.... |

| ABSTRACT Hepatitis E is caused by the hepatitis E virus (HEV) which is currently known to be a zoonotic pathogen transmitted by pigs. In Brazil, there is no information about the circulation of HEV in the swine herd of the Federal District. Therefore, a cross-sectional study was performed with sera from 449 domestic pigs, provided by the Secretary of Agriculture of the Federal District. Blood samples were collected between June and September 2014. A commercially available ELISA kit was used for the detection of IgG antibodies. High seroprevalence of antibodies to HEV was found, since 304 animals showed anti-HEV positive reactions (67.7%; 95% CI = 63.2%, 71.9%). The seropositivity presented no difference by gender or age. The results suggest that HEV... |

| Streptococcus suis is an important swine pathogen in most countries with intensive swine production. S. suis has also been isolated in humans and other animal species. Data regarding serotyping of S. suis isolates from diseased pigs in Cuba using a reference antiserum are not available. S. suis isolates from pigs of four farms located in the western region of Cuba were characterized by serotyping. Most of the isolates was collected from pigs with pneumonia, followed by arthritis cases. Serotypes 2, 4, 8, 15, 16 and 34 were found in isolates from diseased pigs during the period 2002-2008, while serotypes 1, ½, 2, 3, 9, 13, 23, 24 and 31were found from samples collected during 2009-2014. Serotype 2 recovered from systemic (arthritis) and localized... |

| Serum neutralization tests (SN) were performed against classical swine fever virus (CSFV), bovine viral diarrhea virus (BVDV) and border disease virus (BDV) on samples of swine serum collected for screening of antibodies to CSFV, in order to determine the SN value as a differential serological test. Ninety-nine sera out of a sample of 16,664 were positive for antibodies to pestiviruses in an ELISA test which did not distinguish antibodies to different pestiviruses. When submitted to SN, 81 sera were positive for CSFV antibodies only. In 17 sera, crossreactive antibodies to either CSFV, BVDV or BDV were detected. In most of these sera (13 out of 17) the differences between SN titres against the three viruses were not sufficient to estimate which was the... |

| ABSTRACT In this study, we evaluated the effects of substitution of partial and total spray-dried blood plasma (BP) with soy protein concentrate (SPC) in the diet of post-weaning piglets on their performance, intestinal histomorphometry, and blood parameters. Fifty-four castrated male piglets, weaned at an average age of 21 days and an initial average weight of 7.01±0.294 kg, were distributed in a completely randomized block design, with three diets (0%SPC-5%BP, 2.5%SPC-2.5%BP, and 5%SPC-0%BP), six replicates, and three piglets per experimental unit. The experimental feeds were formulated to meet the requirements of the piglets at 21-32 and 33-42 days of age (pre-starter diet) and 43-66 days of age (starter diet). From 21 to 32 and 21 to 42 days of age,... |
