Using Image Analysis Technique for Predicting Light Lamb Carcass Composition
Afonso, João J.; Almeida, Mariana; Batista, Ana Catharina; Guedes, Cristina; Teixeira, Alfredo; Silva, Severiano; Santos, VirgíniaOver the years, numerous techniques have been explored to assess the composition and quality of sheep carcasses. This study focuses on the utilization of video image analysis (VIA) to evaluate the composition of light lamb carcasses (4.52 ± 1.34 kg, mean cold carcass weight ± SD). Photographic images capturing the lateral and dorsal sides of fifty-five light lamb carcasses were subjected to analysis. A comprehe...
Assessment of muscle Longissimus thoracis et lumborum intramuscular fat by ultr...
Silva, Severiano; Patrício, Márcia; Guedes, Cristina; Mena, Elisabete; Silva, António; Santos, Virgínia; Jorge, André [UNESP]Made available in DSpace on 2022-04-29T07:14:33Z (GMT). No. of bitstreams: 0 Previous issue date: 2010-01-01; The intramuscular fat (IMF), recognized by the consumer as marbling, has a favorable effect on meat quality and therefore is an important trait to be assessed. The objective of this work is to predict Longissimus thoracis et lumborum muscle (LM) chemical IMF from marbling traits obtained by analysis of ...
Evaluation of an image analysis approach to predicting primal cuts and lean in ...
Batista, Ana Catharina; Santos, Virgínia; Afonso, João; Guedes, Cristina M.; Azevedo, Jorge; Teixeira, Alfredo; Silva, SeverianoCarcass dissection is a more accurate method for determining the composition of a carcass; however, it is expensive and time-consuming. Techniques like VIA are of great interest once they are objective and able to determine carcass contents accurately. This study aims to evaluate the accuracy of a flexible VIA system to determine the weight and yield of the commercial value of carcass cuts of light lamb. Photos...

Afonso, João; Guedes, Cristina M.; Santos, Virgínia; Morais, Raul; Silva, Josa; Teixeira, Alfredo; Silva, SeverianoThe bioelectrical impedance analysis (BIA) is a non-destructive technique that has been successfully used to assess the body and carcass composition of farm species. This study aimed to predict intramuscular fat (IMF) and physicochemical traits in the longissimus thoracis et lumborum muscle (LM) of beef, using BIA. These traits were evaluated in LM samples of 52 crossbred heifer carcasses. The BIA was performed...

O contributo da Universidade Sénior de Pombal na promoção do envelhecimento ati...
Santos, Virgínia; Lopes, Sara; Lobão, CatarinaIntrodução: O envelhecimento não deve ser encarado como um problema, mas antes como um processo natural, universal e inelutável que ocorre ao longo do ciclo de vida de cada indivíduo. Enquadradas no pilar “aprendizagem ao longo da vida” encontram-se as Universidades Senior, uma resposta socioeducativa que opera num regime informal, ausente de certificações e onde são dinamizadas atividades de cariz social, educ...
Avaliação da qualidade sensorial de carne de borrego Terrincho. Efeito do sexo ...
Rodrigues, Sandra; Pereira, Etelvina; Silva, Severiano; Santos, Virgínia; Azevedo, Jorge; Teixeira, AlfredoEste trabalho tem como objectivo avaliar o efeito do sexo e do peso da carcaça na caracterização sensorial da carne de um produto DOP, o Borrego Terrincho.
The use of ultrasound measurements for monitoring subcutaneous fat and muscle d...
Santos, Virgínia; Lourenço, Ana; Azevedo, Jorge; Silva, Severiano; Santos, Virginia; Guedes, CristinaThroughout the Northeast of Portugal most sheep are raised under extensive production systems with seasonality of feed resource availability. Depending on the severity and length of the scarcity, the ewes use their body reserves, which results in significant variations of body weight (BW) and body condition. Objective techniques, such as real time ultrasonography (RTU), are able to monitor body reserves during ...
On the extremal structure of least upper bound norms and their dual
Sá, E. Marques de; Santos, VirgíniaGiven finite dimensional real or complex Banach spaces, E and F, with norms and , we denote by N[mu][nu] the least upper bound norm induced on . Some results are given on the extremal structures of , the unit ball of N[mu][nu], of its polar , and of , which is the polar of the unit ball of the least upper bound norm N[mu]°[nu]°.; http://www.sciencedirect.com/science/article/B6V0R-4RDBFDR-1/1/816ffee50923a7ec88d...
