Physical measures of the carcass and the chemical composition of Longissimus do...
Neves, J.A.; Freitas, A.; Martins, J.M.; Nunes, J.L.T.The aim of this work was to determine the relationship between physical measures from the subcutaneous tissue and Longissimus dorsi (LD) muscle (area, depth, and width measured between the 3rd and 4th lumbar vertebrae, at the last rib, and between the 3rd and 4th last ribs) and the chemical composition of LD at 70, 80, 90, 100, and 110 kg LW. The content of water, protein, neutral and polar lipids, total and so...

Freitas, A.B.; Neves, J.A.; Martins, J.M.; Nunes, J.T.The aim of this work was to evaluate the effect of fattening diets supplemented with betaine on growth performances and carcass characteristics of Alentejano pigs. Sixteen Alentejano pigs sexually neutralized, with a initial body weight (BW) of 36.3 kg, allocated to open-air individual pens (3m2), were divided into two experimental groups: Group C (n=8) consuming a commercial diet with 150 g/kg crude protein a...

Effect of betaine intake on muscle and backfat characteristics of pigs.
Neves, J.A.; Martins, J.M.; Freitas, A.B.This study was undertaken to investigate the effects of long term betaine intake on the chemical and physical characteristics of m. Longissimus dorsi (LD), and backfat (BKF) of Alentejano (AL) pigs. Purebred AL pigs were allocated to open-air individual pens and fed a commercial (C) diet offered at 85% estimated ad libitum consumption. The pigs were divided into two experimental groups: Group C (n=6), consuming...
Physicochemical characteristics of muscles from free-range reared pigs.
Neves, J.A.; Martins, J.M.; Freitas, A.B.In this study we analysed the chemical composition and physical characteristics of four muscles from Alentejano (AL) pigs, m. Biceps femoris (BF), m. Semimembranosus (SM), m. Longissimus dorsi (LD), and m. Psoas major (PM). Castrated male and female AL pigs allocated to an outdoor rearing area and fed a commercial diet offered at 85% estimated ad libitum consumption, were slaughtered at ~105 kg live weight. BF,...
Alpha-tocopherol content on the semimembranosus muscle of Alentejano pigs reare...
Neves, J.A.; Freitas, A.B.; Martins, J.M.; Nunes, J.T.This trial was undertaken to determine the effect of the rearing system (intensive vs. extensive) over the content of antioxidants (alpha-tocopherol) in the meat of Alentejano pigs. Sixteen Alentejano pigs with an average body weight (BW) of 60 kg were divided in two groups: Group I (n=10) was allocated in open-air individual pens, while Group II (n=6) was maintained in a 3 ha natural pasture. Both groups were ...
Evolution of the composition in fatty acids of the dorsal subcutaneous adipose ...
Neves, J.A.; Freitas, A.B.; Martins, J.M.; Ferraz de Oliveira, M.I.; Abreu, M.C. deThe present work studied the evolution of fatty acid composition in the dorsal subcutaneous fat of free-range Alentejano pigs fed on pasture and acorns. Twenty pigs with a body weight (BW) of ~90 kg were placed in a 2 ha pasture (Lolium westerwoldium and Trifolium incarnatum) and fed daily with 4 kg of acorns. Animals were submitted to biopsies near tail insertion with ~90, ~100, and at slaughter, ~110 kg BW. T...
Effects of a high-fat diet on growth performances and carcass characteristics o...
Freitas, A.B.; Neves, J.A.; Nunes, J.T.; Martins, J.M.The aim of this work was to study the effects of a high-fat diet (6% of sunflower oil) on growth performances and carcass characteristics of finishing Alentejano pigs. 20 Alentejano pigs (castrated female and male) were housed in individual pens (1 x 2 m) in an outdoor area. The animals were divided in two groups with an average live weight of 60 kg. Group 1 was fed a commercial diet (3150 Kcal DE, 14% CP and 1...
Influence of slaughter weight on growth and carcass characteristics of Alenteja...
Freitas, A.B.; Neves, J.A.; Charneca, R.; Nunes, J.T.; Martins, J.M.To study the effects of slaughter weight on growth and carcass characteristics of Alentejano Pig thirty pigs were used. With 20 kg Lw animals were allocated in individual pens at outdoor and fed a commercial diet (15% CP, 3100 Kcal DE) offered at 85% Ad Libitum. Pigs were sequentially slaughtered in groups (n=5) with an average BW of 40, 70, 80, 90, 100 and 110 kg. The growing period, feed intake, feed: gain an...
Effects of body weight on some blood plasma parameters of pigs from the Alentej...
Martins, J.M.; Neves, J.A.; Freitas, A.B.; Nunes, J.T.This work has evaluated the influence of body weight (BW) on some plasma parameters of Alentejano pigs. Thirty castrated Alentejano pigs (~35 kg BW) were allocated in individual pens and fed a commercial diet (0.85x ad libitum). The pigs were slaughtered in groups (n=5) with an average BW of 42.2, 70.9, 80.2, 90.1, 100.5, and 110.2 kg. Plasma samples obtained at slaughter were analysed. Glucose and triacylglyce...
