Loin and fat quality of Portuguese local Alentejano and Bísaro pigs and their c...
Martins, J.M.; Albuquerque, A.; Rodrigues, M.J.; Neves, J.; Freitas, A.; Nunes, J.T.; Charneca, R.Alentejano (AL) and Bísaro (BI) Portuguese local pig breeds cohabited in Ribatejo region for some time. Their crosses (RI pigs) and the products obtained, although appreciated, disappeared in the 1950’s without being scientifically evaluated. To assess the meat quality of RI pigs, castrated males from AL, BI, ALxBI and BIxAL genotypes were studied within the framework of the TREASURE project. Raised in a tradit...
Alentejano and Bísaro pigs and their crosses: genotype effect on loin traits
Martins, J.M.; Albuquerque, A.; Fialho, R.; Neves, J.; Freitas, A.; Nunes, J.T.; Charneca, R.Alentejano (AL) and Bísaro (BI), the two main Portuguese local pig breeds, cohabited in Ribatejo region for some time, but their crosses disappeared in the 1950’s. Although appreciated, no scientific data is available regarding the Ribatejano (RI) pig (ALxBI or BIxAL) animals or their meat. In order to assess the meat quality of RI pigs, castrated male pigs from AL, BI, ALxBI and BIxAL genotypes were studied wi...
Growth, blood, carcass and meat quality traits from local pig breeds and their ...
Martins, J.M.; Fialho, R.; Albuquerque, A.; Neves, J.; Freitas, A.; Nunes, J.T.; Charneca, R.Contrary to intensive pig production, local pig breeds and their production systems are able to respond to the high criteria and expectations of modern society in regard to some environmental aspects, animal welfare, food quality and healthiness. This study proposes the recovery, study and use of a cross between two local breeds, contributing to animal biodiversity conservation and to the income of local pig pr...
Portuguese Local pig breeds: genotype effects on meat and fat quality traits
Martins, J.M.; Fialho, R.; Albuquerque, A.; Neves, J.; Freitas, A.; Nunes, J.T.; Charneca, R.This work investigated the contribution of cross‐breeding between two local Portuguese pig breeds to the conservation of animal biodiversity and income of local pig producers. Quality traits of semimembranosus (SM), gluteus medius (GM) and dorsal subcutaneous fat (DSF) were studied in Alentejano (AL), Bísaro (BI), AL × BI, and BI × AL (Ribatejano—RI) castrated male pigs. Pigs were reared outdoors, fed ad libitu...
The Ribatejano pig: Rebirth of a local population? First results on growth, and...
Martins, J.M.; Neves, J.; Serrano, A.; Abecasis, I.; Albuquerque, A.; Freitas, A.; Nunes, J.T.; Charneca, R.In order to assess the productive performance of the Ribatejano (RI) pig, resulting from a cross between Alentejano (AL) and Bísaro (BI) breeds, castrated male pigs AL, BI, ALxBI and BIxAL were studied within the framework of the TREASURE project. Ten pigs from each genotype, raised in traditional free-range system and fed commercial diets ad libitum, were slaughtered at ~65 kg live weight (LW). Data obtained s...
The Ribatejano pig – rebirth of a local pig population? First results
Neves, J.A.; Martins, J.M.; Serrano, A.; Abecassis, I.; Freitas, A.; Nunes, J.T.; Charneca, R.; Albuquerque, A.A former cross between Alentejano (AL) and Bísaro (BI) breeds, called Ribatejano pig (RI), was quite spread in Ribatejo region until half of the last century and was raised in both borders of Tagus River. Besides the renewed interest of this cross nowadays, no performance data is available regarding the RI (ALxBI and BIxAL) animals or their products, which were studied in the frame of project TREASURE1. In orde...
First reproductive and productive results on “Ribatejano pig”
Charneca, R.; Requetim, C.; Freitas, A.; Neves, J.; Martins, J.M.; Nunes, J.T.The present trail aimed to study the effect of crossbreeding between Alentejano (AL) and Bísaro (BI) swine breeds (“Ribatejano pig”) on some reproductive and productive traits. Nine AL gilts and sows and six BI gilts were crossed with BI and AL boars, respectively. Mating and farrowing dates, prolificacy and litter size at 28d were registered for all sows. The pregnancy length of AL sows was shorter (111±0.4d v...
Utilização de óleo de girassol “alto oleico” na alimentação de porcos alentejan...
Freitas, A.B.; Neves, J.; Martins, J.M.; Nunes, J.T.Este trabalho teve como objetivo a utilização de óleo de girassol rico em ácido oleico na alimentação de suínos Alentejanos destinados à produção de carne para consumo em fresco. O ensaio foi realizado em condições de exploração. Utilizaram-se 12 suínos castrados alojados num parque com uma área de 3 Ha. Com um peso vivo médio de 60 Kg os animais foram divididos em dois grupos de 6 suínos. O grupo 1 (controle) ...
The “montado”: determinant factor affecting the carcass characteristics and the...
Freitas, A.B.; Neves, J.; Nunes, J.T.; Almeida, J.A.The objective of this study was to assess the effect of the finishing system (under montanheira or with commercial feed) on carcass characteristics and dry cured-ham of Alentejano pigs. 24 pigs were fattening until 130 kg LW under montanheira and 24 pigs were fattening with commercial feed. Carcasses of pigs fattened under the montanheira system were slightly heavy (98,38 vs 96,13 kg), with significantly higher...
Produção e azoto recuperado por nabiça e cevada cultivadas em vasos a partir de...
Rodrigues, M.A.; Andrade, João António; Fernandes, H.M.; Fonseca, B.M.; Marrão, Rosalina; Nunes, J.T.; Oliveira, João Manuel; Rego, P.M.O fornecimento de azoto à agricultura biológica pode ser feito através da aplicação de fertilizante orgânicos comerciais. Contudo, estes tendem a ter preços elevados. Assim, é importante obter informação sobre o seu valor agronómico para auxiliar na tomada de decisão. Neste trabalho estudou-se a libertação de azoto e efeito na produção de um fertilizante orgânico autorizado para agricultura biológica por compar...
