Effect of dietary buriti oil on the quality, fatty acid profile and sensorial attributes of lamb meat.

Forty crossbred (Santa Ines × Dorper) male lambs were used to investigate the effect of dietary buriti oil (BOIL) intake on meat quality, fatty acid (FA) composition and sensory attributes. A completely randomized design with five BOIL intake levels (0, 12, 24, 36 and 48 g/kg DM) was used. Increasing dietary BOIL intake linearly reduced the DMI, slaughter weight, cooking loss, shear force, yellowness, 16:0, c9-18:1 FA concentrations, and the delta-9-desaturase activity index computed using c9-16:1 and 16:0 as product and substrate pair, cis-MUFA and Æ©MUFA/Æ©SFA ratio of lamb meat (P ≤ 0.05); however, increasing dietary BOIL intake quadratically increased the energy intake, lipid content and linearly increased the total FA intake, chroma, collagen, total BI, 18:0, 20:3n-6 concentration and sensory attributes of lamb meat (P ≤ 0.05), without affecting health indexes regarding fat consumption. BOIL addition at levels above 24 g/kg DM in lamb diet reduces growth, however, improves tenderness, flavor and "goat" aroma intensity and slightly changes meat FA levels, promoting better acceptance by panelists.

Ethnodirigid study of Medicinal plants used by the population assisted by the Programa de Saúde da Família (Family Health Program) in Marechal Deodoro - AL, Brazil / Estudo etnodirigido de Plantas medicinais utilizadas pela população atendida no Programa de Saúde da Família, Marechal Deodoro, AL, Brasil

Abstract This study aimed to assess diagnosis of Unique Health System (SUS) users profile with regard to herbal medicine. This is a cross-sectional study with observational data collection conducted in the city of Marechal Deodoro, through a semi-structured questionnaire with questions related to socioeconomic data, use, and knowledge of medicinal plants and herbal medicines and satisfaction with the use of medicinal herbs (MH) and interactions of phytotherapeutic drugs (PD). Among the topics, 86.89% of users used herbal medicines often, especially lemon balm (Melissa officinalis L.). It was also observed that the plants are generally used as a sedative (21.74%) and as tea (87.84%). 82.32% of respondents claim to have acquired the knowledge of herbal medicine through a family member and 85.36% make use of medicinal plants without having received any information on the use of MH and PD. 61% of the plants described that coincided with the form of use and therapeutic properties found in the literature. With regard to satisfaction by treatment with MH and PD, it was found that 56.67% are satisfied. Therefore, it is necessary to pay attention to this aspect of usage, in order to avoid possible drug interactions or adverse reactions resulting from the incorrect use.

Resumo Este trabalho teve como objetivo conhecer perfil diagnóstico de usuários do SUS com relação à fitoterapia. Trata-se de um estudo observacional transversal, com coleta de dados realizada no Município de Marechal Deodoro, por meio de um questionário semi-estruturado com perguntas relativas a dados socioeconômicos, utilização e conhecimentos sobre plantas medicinais e fitoterápicos e satisfação com o uso de plantas medicinais (PM) e medicamentos fitoterápicos (MF). Entre os usuários abordados, 87,08% utilizam plantas medicinais frequentemente, principalmente a erva cidreira (Melissa officinalis L.). Também foi observado que as plantas são geralmente usadas como calmante (16,05%) e na forma de chá (68,35%). 82,51% dos entrevistados afirmam ter adquirido o conhecimento sobre fitoterapia através de algum familiar e 85,56% fazem uso das PM e MF sem ter recebido algum tipo de informativo sobre o seu uso. 61% das plantas descritas pelos usuários teve seu uso e terapêutica coincidente com o citado em literatura específica. Com relação a satisfação através do tratamento com PM e MF observou-se que 56,80% estão satisfeitos. O uso de plantas medicinais por parte dos usuários é bastante frequente, principalmente pelo conhecimento acumulado ao longo de gerações. Portanto, se faz necessária maior atenção a esse aspecto de utilização, visando evitar possíveis reações adversas advindas do uso incorreto.

Dietary protein reduction on microbial protein, amino acid digestibility, and body retention in beef cattle: 2. Amino acid intestinal absorption and their efficiency for whole-body deposition.

The objective of this study was to determine the apparent and true intestinal digestibility of total and individual AA, and to estimate the efficiency of whole-body AA retention from individual and total absorbed AA. Four Nellore animals (241.3 kg initial BW) and four crossbred Angus × Nellore (263.4 kg initial BW) cannulated in rumen and ileum were randomly allocated in two 4 × 4 Latin squares. The experiment lasted four 17 d periods, with 10 d for adaptation to diets and another 7 d for data collection. The diets consisted of increasing CP levels: 100, 120, or 140 g/kg of DM offered ad libitum, and restricted intake diet with 120 g CP/kg DM (experiment 1). In experiment 2, forty-four bulls (22 Nellore and 22 crossbred F1 Angus × Nellore) with 8 months and initial shrunk BW 215.0 ± 15.0 kg (Nellore = 208.0 ± 12.78 kg; Angus × Nellore = 221.9 ± 14.16 kg) were used. Eight of those animals were slaughtered at the beginning of the experiment. The remaining 36 bulls were allocated in a completely randomized design with six replicates, in a 2 (genetic groups) × 3 (CP contents) factorial scheme. The amount of essential AA (EAA) and nonessential AA (NEAA) reaching the small intestine increased linearly (P < 0.05) in response to CP content. The apparent digestibility of EAA was not affected (P > 0.05) by CP content, with exception for histidine (P = 0.07, linear effect), leucine (P = 0.01, linear effect), and methionine (P = 0.05, linear effect). Differences existed among AA when compared the apparent digestibility of NEAA. The apparent digestibility of alanine (P = 0.05), aspartic acid (P = 0.07), glutamic acid (P = 0.02), glycine (P = 0.05), proline (P = 0.02), and serine (P = 0.04) responded quadratically to CP content increase. However, the apparent digestibility of cystine and tyrosine was not affected (P > 0.05) by increasing dietary CP. The true intestinal digestibilities of total, essential, nonessential AA, lysine, and methionine were 75.0%, 77.0%, 74.0%, 77.0%, and 86%, respectively. The true intestinal digestibility of total microbial AA was 80%. The efficiency of utilization of total AA for whole-body protein deposition was 40%. The efficiency of utilization of lysine and methionine was 37% and 58%, respectively. It was concluded that the AA flow to the omasum increases in response to dietary CP content. In addition, there are differences among AA in the efficiency that they are used by beef cattle.
