OPTIMIZAÇÃO DA MATÉRIA-PRIMA: COM BASE NO PESO DE ABATE
Freitas, AmadeuAbordam-se os efeitos do peso de abate (115 -130 Kg) sobre performances de crescimento (ganho médio diário e número de dias para se atingir o peso ao abate), características quantitativas e qualitativas da carcaça (peso de carcaça, rendimento, peças de corte e composição tecidular) e a composição tecidular e química da perna e pá (peso e percentagem de músculo, gordura e osso) de suínos de raça Alentejana engo...
OPTIMIZATION OF THE RAW MATERIAL: BASED UPON THE SLAUGHTERING WEIGHT
Freitas, AmadeuThe objective of this study was the study of the effects of the slaughter weight (115-130 Kg) on growth performances (daily gain and days to obtain slaughter weight), carcass characteristics (hot carcass weight, dressing percentage, cuts of carcass and tissue composition of carcass), and on tissue and chemical composition of legs and shoulders (weight and percentage of muscular, adipose and bone tissues) of Ale...
Influence de l'homogénéité des portées sur la prise colostrale et la mortalité ...
Charneca, Rui; Lima, Fábio; Freitas, Amadeu; Nunes, José; Le Dividich, JeanWithin‐litter variation in birth weight is a factor relevant to pig production. This study set out to compare colostrum intake and postnatal mortality in litters of uniform or heterogeneous birth weight. The study involved 52 sows (Large White x Landrace) and their litters. To create two litters, either uniform (U) or heterogeneous (Control, C) in birth weight, piglets from two sows farrowing concomitantly were...
Relationship between birth order and birth weight of the pig
Charneca, Rui; Freitas, Amadeu; Nunes, José; Le Dividich, JeanThe objective of this study was to determine whether birth weight of the pig is related to its birth order. The study involved 292 sows from 2 genotypes (Large White x Landrace crossbred (LL), n= 247 and Alentejano (AL), n=45) of mixed parity and their piglets. Most sows farrowed naturally. Each piglet was identified, weighed (± 1g) (mummies excepted) and its birth order (BO) recorded within 2 min of birth. A t...

Effect of long-term betaine supplementation on chemical and physical characteri...
Martins, José M; Neves, José A; Freitas, Amadeu; Tirapicos, José LBACKGROUND: The use of betaine as a dietary supplement to reduce fat deposition and increase lean muscle mass in pigs is increasing. However, there is no available information on its effect on the physical and chemical (i.e. fatty acid (FA) profile) characteristics of pork. RESULTS: The effects of long-term betaine intake (1 g betaine kg−1 diet for 20 weeks) on the chemical and physical characteristics of Muscu...
COMPOSIÇÃO QUÍMICA DO LOMBO CURADO: EFEITO DA MATÉRIA-PRIMA
Neves, José Alberto; Martins, J.; Freitas, AmadeuFoi utilizada matéria-prima proveniente de 3 diferentes sistemas de produção, cujas matrizes produtivas são conhecidas: 1) porcos de raça Alentejana engordados em “montanheira” (PAM); 2) porcos de raça Alentejana DOP e 3) porcos industriais (PI). Os lombos frescos foram identificados e sujeitos ao mesmo processo tecnológico de elaboração na fábrica Companhia Alentejana de Enchidos Tradicionais. Foi determinada ...
A raça suína Alentejana e a valorização dos montados
Freitas, AmadeuA raça suína alentejana é, desde tempos remotos, explorada em regime extensivo, utilizando e valorizando os recursos naturais do sistema agro-silvo-pastoril em que se insere.Ontem como hoje, o acabamento dos porcos na montanheira-engorda intensiva dos animais nos montados de azinho e sobro, entre o final de outubro, meados de Novembro até ao final de Fevereiro- constitui o elemento estratégico do sistema de pro...
Porco Alentejano de montanheira
Freitas, AmadeuA raça suína Alentejana e os montados estão historicamente associados.O sistema de produção do porco Alentejano de montanheira protege e potencia uma raça autóctone,valoriza ambiental e economicamente os montados,evita a desertificação e enriquece a passagem rural e origina produtos de elevada qualidade, suportados pelo saber fazer tradicional, que enriquecem o património histórico, cultural e social do Alentej...
Betaine supplementation affects the cholesterol but not the lipid profile of pigs
Martins, José M.; Neves, José A.; Freitas, Amadeu; Tirapicos, José L.This study was undertaken to investigate the effects of long termbetaine intake on the cholesterol and lipid profile of Alentejano (AL) pigs. At 36 kg body weight (BW), castrated male and female pigs fed a commercial (C) diet, were divided into two groups: i) Group C, consuming the C diet; and ii) Group CB, consuming the C diet supplemented with 1 g/kg betaine. Pigs were slaughtered at ,100 kg BW. Fasting plasm...
