Influência da imunocastração (Bopriva®) no ganho de peso, características de carcaça e qualidade da carne de bovinos Nelore

The objective of this study was evaluate the effects of immunocastration on body weight gain, carcass characteristics and meat quality of Nellore beef cattle. Eighty Nellore beef cattle, with initial body weight of 357 +/- 8.63 kg, were placed in feedlots and distributed in two treatments (40 animals per treatments) as follow: one - non-vaccinated bulls and two - immunocastrated bulls (Bopriva (R), Pfizer Animal Health). The animals placed on treatment two were vaccinated in two doses, first application 30 days before they arrive on the feedlots and second on the day they arrive on feedlots. After 67 days of experimental period, was calculated the daily gain of live weight in kg/day of the 80 animals and selected 20 animals from each treatment for the slaughter and carcass evaluations, and ten from each group for the meat analyzes. The data were submitted to analysis of variance. Immunocastrated animals showed lower daily weight gain, hot carcass weight, carcass yield, pH, leg thickness, muscle depth, loin muscle area, carcass muscle percentage, shear force and moisture. However, this animals had higher concentration of lactate and cortisol blood, chest depth, fat thickness, finishing degree, a *, b * and c*, liquid loss in thawing process, myofibrillar fragmentation index and ether extract of meat when compared to non-vaccinated bulss. The immunocastration (Bopriva (R)) is an alternative for improving the quality of meat by the higher fat deposition and by the reduction of the shear force of the meat when compared to non-vaccinated bulls.

Maturação de carne bovina

A maturação de carnes bovinas é uma importante ferramenta utilizada pelas empresas frigorificas visando um produto final com melhores características sensoriais, cada vez mais apreciadas pelos consumidores finais. O objetivo deste trabalho é elucidar os processos bioquímicos ocorrentes na musculatura que levam à sua transformação em carne e as tecnologias utilizadas visando o processo de maturação, que se consiste em manter a carcaça durante refrigeração por um tempo determinado. Durante a refrigeração, a temperatura, o pH e os níveis de ATP na musculatura determinam a ação das enzimas calpaínas e calpastatinas, que atuam sobre os filamentos de actina e miosina degradando a linha z, tornando assim a carne mais macia

Ciência da carne: a linguagem gráfica da anatomia humana

This monograph seeks to provide an exposition and theoretical examination of Ciência da Carne (“Science of the Flesh”), a series of artworks in woodcut printing executed after research into the artistic aspects of Human Anatomy, done throughout the Graduate Course in Visual Arts at UNESP’s Art Institute. Traditional procedures of naturalistic representation of the human figure often adopt the scientific basis of Anatomy as a means of interpreting the surface contours of the body from its inside out. The historical connection between Anatomy and Art, however, is not merely accidental, for it is integral to the development of both disciplines, which find themselves deeply related in the human impulse for self-discovery and reinvention of its own likeness. The series of artworks collected in Ciência da Carne explores, through the particular graphical language provided by woodcut printing, abstract arrangements of isolated anatomical elements, at once removed from the context of traditional figurative representation and from the didactic goals of medical illustration.

A influência do estresse sobre a qualidade da carne

The meat quality is evaluated by consumers according to their physical characteristics, such as color, texture, juiciness, tenderness and odor. The stress during the life of the animal and at the moment before the slaughter may be responsible for changes in the transformation of muscle into meat. Such changes may lead to the appearance of DFD (Dark, Firm and Dry) and PSE (Pale, Soft and Exudative) meats, which are poorly accepted in the market – because of their unusual aspect – and inadequate to industrial processing. Factors related to the handling, loading, transport, unloading, resting period and stunning are singled out as critical, since that, in these phases the animals are subjected to adverse situations to which they are accustomed. The aim of this study is to identify the process of ante-mortem and the slaughter itself in which the animals are subjected to stressful situations, as well as the consequences of stress on meat quality

Susceptibilidade ao estresse e qualidade de carne de suínos suplementados com diferentes níveis de Ractopamina

The ractopamine is a β-adrenergic agonist used as a divider of energy in diets for finishing pigs. However, research shows that this additive may effect on welfare and meat quality. In this context, the aim was to evaluate the influence in three levels of inclusion of ractopamine (0, 5 and 10ppm) in commercial pigs diet (castrated, males and females, n = 340) for 28 days pre-slaughter on the welfare and meat quality. The wellbeing was assessed by the behavior of animals, number of skin damages, carcass damages and physiological stress (lactate, cortisol and creatinine phosphokinase). The evaluation of meat quality was performed by analyzing pH, color, drip and cooking loss, shear force and marbling of the longissimus dorsi muscle of 90 selected pigs. There was no influence of treatments on the behavior, the total number of skin damages and carcass damages or concentration of cortisol and lactate. However, levels of the enzyme creatine phosphokinase (CPK) increased in pigs supplemented with ractopamine. This shows that, somehow, this additive led to physiological changes in animals that consumed it. PH and drip loss did not change by the addition of ractopamine in the diet. In contrast, the Longissimus dorsi of pigs that received ractopamine presented less intense red color and no difference was found in L* and b*. The inclusion of ractopamine in the diet reduced the degree of marbling, cooking loss and tenderness of the muscle. Supplementation did not lead to behavioral change, increased incidence of injury, plasma cortisol and lactate and minimal impact on meat quality. However, there was evidence that the animals fed the additive suffered physiological changes

Jejum no pré-abate de suínos: bem estar animal e qualidade da carne

In the pre-slaughter management of pigs there are stressors, which depending on the duration or severity, are able to alter the quality of meat. One of the factors considered critical to the welfare is the fasting period in the farm. This practice is fundamental and proven relevance in the production chain. Besides the effects on meat quality and welfare of pigs, fasting is among the main factors responsible for the incidence of skin lesions, can significantly influence the incidence of esophagogastric ulcers and is also important to avoid any contamination of carcasses by gastrointestinal contents. When fasting is done right, it has a positive impact on welfare, meat quality and conditions of welfare during the pre-slaughter management of pigs
