O objetivo deste trabalho foi avaliar o efeito da imunocastração e da suplementação com ractopamina na qualidade do lombo suíno processado com sal e tripolifosfato de sódio. Os tratamentos consistiram de condição sexual dos suínos (fêmeas, machos castrados fisicamente e imunocastrados) e suplementação ou não com ractopamina na dieta de terminação. Os cortes de lombos submetidos ao processamento com tripolifosfato de sódio e sal foram avaliados quanto aos parâmetros físico-químicos, microbiológicos e sensoriais. Não houve interação entre condição sexual e ractopamina nas características do lombo cru. A adição de ractopamina na dieta aumentou a força de cisalhamento dos lombos crus. Também não houve efeito da condição sexual nem da ractopamina na perda de...

The study verified the influence of different nutritional levels of the dams, before parturition, the weaning age of the lambs and the finishing system on lamb muscle fiber morphology and meat quality. Ile-de-France × Bergamacia crossbred dams grazing on natural grassland were divided into two groups: 1) nutritional supplement 30 days before the parturition (SUPL), and 2) no nutritional supplement (NS). These groups were further subdivided by weaning age of the lambs, which corresponded to either 45 or 60 days. The weaned lambs from each of the previous groups were also divided into different finishing systems: confined and fed a complete diet (CD), confined and fed hay (H) and kept on grassland (P). The lambs were slaughtered at 30 kg live weight (CD and...

Com o objetivo de avaliar o efeito de diferentes níveis de IGF-I sobre os indicadores de atividade celular hepática e intestinal em bezerros recém-nascidos, 42 vacas holandesas gestantes foram aleatoriamente distribuídas em dois grupos. O grupo rbST recebeu hormônio de crescimento (500 mg rbST) e o grupo controle recebeu injeção de vitamina E. As aplicações se iniciaram aos 35 dias pré-parto e foram repetidas a cada 14 dias até o parto. Os recém-nascidos foram distribuídos aleatoriamente nas seguintes idades de abate: após o nascimento e sem a ingestão de colostro; e 2 e 7 dias de vida com ingestão de colostro das respectivas mães. O delineamento experimental utilizado foi o inteiramente casualizado, em estrutura fatorial 2 x 3, correspondendo aos grupos...

Differential growth retardation and Myofibrillar fragmentation in rats submitted to feed restriction and realimentation
Provedor de dados: 63
Autores: Leonardo,Eric Franchi; Delgado,Eduardo Francisquine; Bagaldo,Adriana Regina; Lanna,Dante Pazzanese Duarte; Paz,Claudia Cristina Paro de.
Feed regimens alter muscle growth rate, hence they might impact the proteolytic system involved in tenderization during meat conditioning. The aim of this project was to verify the effects of feed restriction regimens on muscular and animal growth and their impact on postmortem myofibrillar fragmentation. The regimens were: 1) Feeding ad libitum for 11 d (Al/2); 2) Feed restriction (60% of Net Energy for maintenance - NEm) for 11 d (Rt/2); 3) Ad libitum for 22 d (Al); 4) Ad libitum for 4 d and feed restriction (60% NEm) for 18 d (Rt); 5) Ad libitum for 19 d and 3 d of fast (Ft); 6) Feed restriction (60% NEm) for 11 d and ad libitum until 22 d (Ral). The regimens Al/2 and Rt/2 had different intestine weights (19.3 ± 1.1 and 15.8 ± 1.9 g, respectively; P...

Pork loin two-toning and drip loss in relation to steak cross-section anatomical position, plasma and exudate glucose
Provedor de dados: 63
Autores: Ramos,Patricia Maloso; Delgado,Eduardo Francisquine.
Perception of color and its relationship to water holding capacity are important for defining the yield and quality of the pork production process. The aim of this study was to identify the relationship among color measurements taken at various anatomical positions in the cross-sectional surface of pork loin steak, and measurements of fluid exudation and its glucose concentration, as well as the impact on these attributes due to plasma glucose at slaughter. Two assays were conducted sequentially: i) investigation of the surface color parameters at different anatomical positions in the pork loin cross-section and their relationship to general exudation; and ii) the effect of plasma glucose levels on surface color variables, drip loss and glucose exudate...

Brazilian consumers' perception of tenderness of beef steaks classified by shear force and taste
Provedor de dados: 63
Autores: Delgado,Eduardo Francisquine; Aguiar,Ana Paula; Ortega,Edwin Moisés Marcos; Spoto,Marta Helena Fillet; Castillo,Carmen Josefina Contreras.
The knowledge of consumer perception of meat tenderness and taste is essential to forecast a Brazilian quality value-based beef market. This study aimed to verify perception of tender (WBSF &lt; 4.1 kg) from tough (&gt; 4.8 kg) strip loin steak or uncharacteristic (calcium-treated/Ca-IM) and normal (non-calcium/NO-Ca) meat taste by consumers according to gender, age, education and income levels. Steaks were previously classified by shear force measurements as tender or tough. Each consumer was served a paired sample of one tender and of one tough steak, which were either Ca-IM or NO-Ca treated before tenderness classification. Three hundred and eight consumers answered a nine-point intensity (tenderness) and hedonic (taste) scales evaluation questionnaire....

Sarcoplasmatic and myofibrillar protein changes caused by acute heat stress in broiler chicken
Provedor de dados: 63
Autores: Santos,Carolina de Castro; Delgado,Eduardo Francisquine; Menten,José Fernando Machado; Pedreira,Aparecida Carla de Moura; Castillo,Carmen Josefina Contreras; Mourão,Gérson Barreto; Brossi,Camila; Silva,Iran José Oliveira da.
Acute heat stress (AHS) modifies the structure of myofibrils affecting functional properties of meat, mainly the water holding capacity. This experiment aimed to identify changes in proteolysis and migration between the myofibrillar and sarcoplasmatic fractions due to pre-slaughter AHS. Myofibrillar fragmentation index (MFI), SDS-PAGE, western blot of vinculin (WB) and shear force (SF) were determined. Six hundred broilers (Gallus gallus) were slaughtered in three different days (ST). In each ST, groups of ten animals were placed in transport crates and submitted to AHS (35ºC, 75 - 85% RH) for 2 hours. Simultaneously, the non-stressed broilers (NS) were kept in thermoneutral environment (22ºC, 83 ± 6.6% RH) within the crates in the same density. After...

Intestinal histomorphology in Pseudoplatystoma fasciatum fed bovine colostrum as source of protein and bioactive peptides
Provedor de dados: 63
Autores: Rodrigues,Ana Paula Oeda; Pauletti,Patricia; Kindlein,Liris; Delgado,Eduardo Francisquine; Cyrino,José Eurico Possebon; Machado-Neto,Raul.
Histological responses of the intestine are key for evaluating nutritional value of feed ingredients, since the organ is not only the chief site of feed digestion and nutrient absorption but also plays an important immunological function. Histomorphological alterations were evaluated in the intestine of juvenile striped catfish, Pseudoplatystoma fasciatum, fed diets containing 0 (control), 10 or 20% inclusion of lyophilized bovine colostrum (LBC), as source of protein or bioactive peptides, for either 30 or 60 days. Fish fed 20LBC presented at 60d a distinct pattern of macrophages and, some of them, higher number of vacuoles in rectum mucosa. The thickness of the muscle layer (TML) in fish fed diets with LBC was higher in the first portion of medium...
