Legislação e ferramentas de gestão no controle de qualidade da matéria-prima na fabricação de rações

The objective of this review was to gather theoretical knowledge about legislation and management tools in the quality control of raw material in the production of feed for production animals, describing the regulation and inspection in the processes involved, highlighting the importance that such procedures in the final product result. Thus, it is evident that the quality control of the raw material is essential in order to guarantee the safety of a reliable final product, which meets the market and consequently the animal requirements, which is close to the specifications or standards established for which it was created and that complies with current legislation and inspections of federal agencies related to the sector. It is essential to use such management tools in the quality and safety of food offered to production animals. In which, Good Manufacturing Practices and Standard Operating Procedures are essential prerequisites for the implementation of Hazard Analysis and Critical Control Points.

Susceptibility of Rhipicephalus (Boophilus) microplus to acaricides in dairy cattle in the region of Goiano West, Brazil

The Rhipicephalus (Boophilus) microplus is the main cattle tick, responsible for large losses in Brazilian cattle. Control of R. (B.) microplus relies almost exclusively on the use of chemicals. But increasingly this species of tick has shown resistance to products used mainly by the poor use of acaricides. The goal of this work is to evaluate the situation of the resistance of the cattle tick Rhipicephalus (B.) microplus to acaricides used in the Western Goiano, as well as analyze the factors involved in this resistance. Tests will be performed immersion Riphicephalus ticks (Boophilus) microplus using ten commercial products with different active ingredients, in order to verify the effectiveness rate of products available acaricides. After the test results, it was found that the product was more effective Cypermethrin 6.0 g + 50 g Chlorpyrifos 98.20% and was less effective Deltrametrina 25 g with 19.87%, since the majority of active ingredients did not show good efficacy on the tick population in the region Goiano West.

Avaliação de parâmetros fisiológicos em búfalas da raça Murrah

The aim was to evaluate the rectal, body superficial temperature and respiratory frequency in Murrah breed buffalos. The study was conducted in farm located in Pires do Rio city, Goiás state. It was evaluated 07 buffalos of Murrah breed. The average superficial temperature measured at 13:00, 14:00 e 15:00 hours was 32.35±0.48, 33.20±0.47 e 32.45±0.44 o C, respectively. The average rectal temperature at 13:00, 14:00 e 15:00 hours was 38.25±0.19, 39.05±0.22 e 38.48±0.24 o C, respectively. The respiratory frequency at 13:00, 14:00 e 15:00 hours was 22.85±4.45, 27.42±4.86 e 22.28±3.14 rpm. The evaluation of physiological parameters does not show that the animals reached the thermic stress during the evaluation.

Avaliação de carcaça de bovinos da raça Tabapuã com ultrassonografia

Measures ultrasound enable the knowledge level of muscularity, the thickness of subcutaneous fat of the animal and the degree of marbling of the meat by measuring in vivo animal. The objective of this study was to evaluate carcass traits of 20 animals Tabapuã, quantifying the mean values and standard deviations of carcass traits and estimate simple correlations between body weight and ultrasound measurements. Carcass characteristics were measured by ultrasound ribeye area (AOL), fat thickness (EGS), obtained between the 12th and 13th rib, marbling score (MAR), ratio: height x width of the counterfilet (RATIO), AOL/100 and EGS/100. The estimates for body weight, AOL, AOL/100, RATIO, MAR, EGS and EGS/100 averages: 472.23 ± 140.80, 75.78 ± 21.17, 16.33 ± 2.63, 0 45 ± 0.04, 1.03 ± 0.19, 2.33 ± 0.77, 0.52 ± 0.11, respectively. The value of AOL found indicates animals with high yield of meat cuts.

Simulação de dados para avaliação econômica do sistema de cria de bovinos de corte em pastagem de Brachiaria brizantha cv. Marandu

Objetivou-se proceder a simulacoes de dados de producao de bovinos de corte, na fase de cria, por meio de um rebanho base composto por 500 femeas da raca Nelore, acima de 36 meses submetidas a IATF, e 20 touro de repasse. Foram simuladas 5 situacoes diferentes: S1: 60%; S2: 70%; S3: 80%; S4: 85% e S5: 90% de natalidade. Indices de natalidade de 60 ate 80% com descarte de 50% de femeas vazias, a margem liquida fica negativa, ficando positiva apenas com indices acima de 80%.
