Partial replacement of soybean meal with Chlorella vulgaris in broiler diets in...
Boskovic Cabrol, Marija; Martins, Joana C.; Malhão, Leonardo P.; Alves, Susana P.; Bessa, Rui J.B.; Almeida, André; Raymundo, Anabela; Lordelo, MadalenaAlternative feed ingredients, such as microalgae, may be more sustainable in comparison to conventional feedstuffs that need large amounts of arable land and are often imported. This study evaluates the effects of Chlorella vulgaris various inclusion levels in the diet of broiler chickens on performance, carcass yield, organ measurements, breast meat quality, fatty acids profile, and antioxidant capacity. A tot...
Fatty Acid Composition of M. Biceps Femoris of Edible Dormouse (Glis glis L.)
Paden, Lana; Alves, Susana P.; Bessa, Rui J. B.; Almeida, André M.; Bujanic, Miljenko; Konjevic, DeanThis study aimed to investigate the fatty acid (FA) composition of edible dormouse m. biceps femoris in both sexes. More than 20 FA were identified in the muscle, with the 18:1cis-9 (oleic acid) being the most abundant in both sexes, comprising more than 50% of total FA in muscle. The most dominated FA were monounsaturated (MUFA), followed by saturated FA (SFA) and polyunsaturated FA (PUFA), reaching 54.8%, 25....
Technological feasibility of couscous-algae-supplemented formulae : process des...
Khemiri, Sheyma; Nunes, Maria Cristiana; Bessa, R.J.B.; Alves, Susana P.; Smaali, Issam; Raymundo, AnabelaThe aim of this work was to develop functional couscous in a traditional Tunisian manner (hand rolling), enriched in algae biomass (6% w/w). Four Chlorella vulgaris (C. vulgaris) biomasses and one mixture of C. vulgaris and two macroalgae biomasses (Ulva rigida and Fucus vesiculosus) were used. The C. vulgaris strain was subjected to random mutagenesis and different culture conditions (Allmicroalgae), resulting...
Effects of increasing doses of condensed tannins extract from Cistus ladanifer ...
Guerreiro, Olinda; Alves, Susana P.; Costa, Mónica; Duarte, Maria F.; Jerónimo, Eliana; Bessa, R.J.B.Cistus ladanifer (rockrose) is a perennial shrub quite abundant in the Mediterranean region, and it is a rich source in secondary compounds such as condensed tannins (CTs). Condensed tannins from C. ladanifer were able to change the ruminal biohydrogenation (BH), increasing the t11–18:1 and c9,t11–18:2 production. However, the adequate conditions of the C. ladanifer CTs used to optimize the production of t11–18...
Freeze‑dried Nannochloropsis oceanica biomass protects eicosapentaenoic acid (E...
Vitor, Ana C. M.; Francisco, Alexandra Eduarda; Silva, Joana; Pinho, Mário; Huws, Sharon A.; Santos-Silva, José; Bessa, R.J.B.; Alves, Susana P.Eicosapentaenoic acid (EPA) from freeze-dried biomass of Nannochloropsis oceanica microalgae resists ruminal biohydrogenation in vitro, but in vivo demonstration is needed. Therefore, the present study was designed to test the rumen protective effects of N. oceanica in lambs. Twenty-eight lambs were assigned to one of four diets: Control (C); and C diets supplemented with: 1.2% Nannochloropsis sp. oil (O); 12.3...

A comparison between the quality of eggs from indigenous chicken breeds and tha...
Lordelo, Madalena; Cid, Joana; Cordovil, Cláudia; Alves, Susana P.; Bessa, Rui J.B.; Carolino, InêsThere is an increased interest in animal products from more sustainable farming practices, which may include using local breeds. In addition, maintaining biodiversity is important, and naturally, indigenous breeds of chickens are well adapted to the local environmental conditions. In the current study, 286 eggs from 4 Portuguese breeds of chickens (Branca, Amarela, Pedr^es Portuguesa, and Preta Lusit^anica) and...
Discrimination of meat produced by Bos taurus and Bos indicus finished under an...
Bressan, Maria C.; Rodrigues, Erika C.; Rossato, Lizandra V.; Neto-Fonseca, M. Isabel; Alves, Susana P.; Bessa, R.J.B.; Gama, LuisMeat obtained under commercial conditions shows considerable variability, mostly due to genetic background and production system. In this study, meat physicochemical properties and fatty acid profiles were analysed to investigate the feasibility of using them as tools to discriminate between meats produced by different genetic groups and finishing systems. Samples of the Longissimus thoracis were collected from...
Effect of dietary neutral detergent fibre source on lambs growth, meat quality ...
Santos-Silva; Francisco, Alexandra Eduarda; Alves, Susana P.; Portugal, Paula; Dentinho, M.T.P; Almeida, João; Soldado, David; Jerónimo, ElianaABSTRACT - With this trial we have tested the effects of structural and chemical composition of neutral detergent fibre (NDF) of the diet on lamb fatty acid composition of meat and subcutaneous fat. Twenty lambs, were fed complete diets with low starch and similar NDF content of different origin (ground alfalfa or soybean hulls). Animal performance and product quality were not affected by treatments. Rumen pH i...
Detailed dimethylacetal and fatty acid composition of rumen content from lambs ...
Alves, Susana P.; Silva, José Santos; Cabrita, Ana R. J.; Fonseca, António J. M.; Bessa, Rui J. B.Lipid metabolism in the rumen is responsible for the complex fatty acid profile of rumen outflow compared with the dietary fatty acid composition, contributing to the lipid profile of ruminant products. A method for the detailed dimethylacetal and fatty acid analysis of rumen contents was developed and applied to rumen content collected from lambs fed lucerne or concentrate based diets supplemented with soybean...
