Fatty acid, chemical, and tissue composition of meat comparing Santa Inês breed sheep and Boer crossbreed goats submitted to different supplementation strategies.

Abstract: To compare the fatty acid (FA) composition, and chemical and tissue composition of meat, 24 uncastrated males, 12 sheep of the Santa Ines breed, and 12 crossbred goats (F1 Boer × undefined breed) with the weight of 24.3 ± 2.38 kg. The animals were distributed in a randomized block design and treatments were arranged in a 2 × 2 factorial design, two small ruminant species/breed (Boer crossbreed goat × Santa Ines breed sheep), and two supplementation strategies (energy × protein energy). There was not an interaction between the small ruminant species and the supplementation on average daily gain, tissue composition, chemical composition, or FA profile of the longissimus lumborum muscle. Sheep presented greater weight and yield of fat in the subcutaneous, intermuscular, and total depots than goats, which results in better finishing of the sheep for slaughter. Goat meat presented a lower lipid concentration than sheep meat. The protein-energy supplementation increased oleic acid, ΣUFA, ΣMUFA, hypocholesterolemic/ Hypercholesterolemic index, and enzymatic activity Δ9–desaturase C18 and decreased SFA capric acid in the muscle when compared with energetic supplementation. In Caatinga biome conditions, Boer crossbreed goats meat has a lower concentration of lipids and a healthier FA composition compared with Santa Ines breed sheep because it has a lower SFA and greater PUFA content, which are sources of n−3 and n−6, which may contribute to the reduction of blood cholesterol (LDL). In addition, protein-energy supplementation also improved the quality of animal fat compared with supplementation only with the energetic concentrate, regardless of species.

Organophosphorus Pesticide in Sapodilla (Manilkara zapota) Fruit

Abstract: A method based on QuEChERS (quick, easy, cheap, effective, rugged, and safe) extraction and gas chromatography-mass spectrometry (GC-MS) detection was described for the pesticides dichlorvos, disulfoton, ethoprophos, parathion methyl, fenchlorphos, chlorpyrifos, azinphos methyl and prothiofos in sapodilla. For all compounds studies, it was observed a strong matrix effect showing the need to use matrix matched calibration strategy. Method was validated, and good linearity (R > 0.99) was obtained for all pesticides studied with limits of detection (LODs) and quantification (LOQs) ranging from 0.01 to 0.06 mg kg-1 and 0.03 to 0.2 mg kg-1, respectively. Recovery studies were performed at different levels (0.08, 0.10, 0.14, 0.20, 0.35 and 1.17 mg kg-1) and showed good results (between 70 and 120% with relative standard deviation (RSD) < 20%). A statistical test was applied to the coefficients of the analytical curves obtained in the sapodilla matrix. Analyses of commercial samples showed chlorpyrifos were detected in about 70 and 33% for fruit and pulps samples, respectively. It should be noted that chlorpyrifos is not permitted in sapodilla crops by ANVISA and EC guidelines.

Problemas vividos por las adolescentes durante la gestación.

Abstract: Pregnancy in adolescence brings with it serious biological implications, family problems, psychological issues, economic stress, besides the negative social repercussions that affect the adolescent and society as a whole. Consequently, in response to the problem a study was developed with the objective of characterizing the socio-demographic profile of teenage mothers and to aid in the identification of the problems they suffer during pregnancy. The study was descriptive-exploratory, conducted in the Municipality of Massape-CE, with 20 adolescents all of whom had recently given birth between the period of October 15th to November 30th, 2004. Open-ended and Close-ended questions were asked. The adolescents were all between the ages of 14 and 19 years old, 45% were single, 60% had not finished high school, 50% had family incomes below that of one minimum monthly salary, 60% were in their first pregnancy, 10% had had an abortion. 80% presented biological, emotional, social, and economic problems. This study suggests the application of more interventionary pre-natal assistance for adolescents with the intention of minimizing risks and damages.

Mineralization of nitrogen and carbon from organic compost from animal production waste

Abstract: Elucidating the mineralization of organic composts makes it possible to understand the release of nutrients to plants The objective of this study was to evaluate the mineralization of nitrogen (N) and carbon (C) from organic compost from residues of the production and slaughter of small ruminants, applied on a Neossolo Fluvico (Fluvents) The compost consists of remains of grass (forage), manure and slaughter residues such as blood, viscera and the carcass of goats and sheep Under laboratory conditions, two experiments were conducted in a completely randomized design, considering the doses of organic compost at the following levels: zero; 375, 75, 15 and 30 Mg ha-1 For the N and C mineralization tests, 11 and 32 collection times (sampling periods) were evaluated, respectively Inorganic N content (ammonium and nitrate) was measured in the N mineralization test, and CO2-C concentration was quantified in the C mineralization test The largest increments between the applied doses of organic compost from residues of the production and slaughter of small ruminants were 70% and 69% for potentially mineralizable N and C, with amounts of 75 and 30 Mg ha-1 at doses of 375 and 75 Mg ha-1, respectively Organic C and N from residues of the production and slaughter of small ruminants are rapidly mineralized in the soil (up to 45 days) due to their low C/N ratio
