Direct cost method applied to calculate milk production costs
Freitas, José Leoncio Delmondes Pereira; Muniz, Evandro Neves; Santos, Anselmo Domingos Ferreira; Freitas , Sônia Magna Moura DelmondesThe objective was to apply direct costing (DC) methodology to calculate dairy farms costs located in the semiarid region of Sergipe, Brazil. Productive and financial data were used from 30 dairy farms, in which milk market is the farms primary activity. Costs were segregated as fixed and variable, as profitability index, contribution margin (CM) and net income (NI). Profit before interest, taxes, depreciation a...
Allometric growth of ½ Dorper + ½ Santa Inês lambs slaughtered with different s...
Santos, Camilo Azevedo; Macedo, Francisco de Assis Fonseca de; Santos, Gladston Rafael de Arruda; Santos, Anselmo Domingos FerreiraThe objective of this work was to evaluate the allometric growth, the correlation of the cuts with the half carcasses, and the muscularity index of the leg of ½ Dorper + ½ Santa Inês lambs slaughtered with 2.0, 3.0, and 4.0 mm of subcutaneous fat thickness (SFT). Twenty-four non-castrated male lambs were used, being distributed according to their weight into three collective pens. Slaughtering occurred as the l...
Physicochemical characteristics of dry aged beef from younger Nellore bulls sla...
Passetti, Rodrigo Augusto Cortêz; Prado, Ivanor Nunes do; Macedo, Francisco de Assis Fonseca de; Teixeira, Alfredo; Cardoso, Claudia Andréa LimaReducing slaughter age can improve meat quality and reduce costs, while an ageing process can result in more standardized products. Thus, the objective of this paper was to measure the physicochemical characteristics of dry aged meat from younger Nellore bulls slaughtered at different body weights. Twenty-four Longissimus thoracis from young bulls (14 months of age) finished in a feedlot at body weights of 350,...

Farias, Juliana Santos; Macedo, Francisco de Assis Fonseca de; Santos, Gladston Rafael de Arruda; Barbosa, Leandro TeixeiraO efeito da maturação nas características físicas (pH, cor, perda de peso na cozedura e força de cisalhamento) e biológico (microbiologia, no que se refere aos mesófilos e psicrotrófilos e comprimento do sarcômero) do músculo Longissimus thoracic lumborum do gado Nelore adulto foi avaliado durante quatro períodos de maturação (0, 7, 14 e 21 dias) e duas espessuras de corte (2,5 e 7,5 cm). Foram adquiridos 64 mú...

Farias, Juliana Santos; Macedo, Francisco de Assis Fonseca de; Santos, Gladston Rafael de Arruda; Barbosa, Leandro TeixeiraThe effect of maturation on the physical (pH, color, weight loss on cooking, and shear force) and biological (microbiology, concerning mesophiles and psychrotrophiles, and sarcomere length) characteristics of the Longissimus thoracic lumborum muscle of adult Nellore cattle was assessed over four maturation periods (0, 7, 14, and 21 days) and two cut thicknesses (2.5 and 7.5 cm). Sixty-four Longissimus thoracic ...

Araujo, Helber Rodrigues; Rangel, José Henrique de Albuquerque; Fagundes, Jailson Lara; Muniz, Evandro Neves; Santos, Daniel de OliveiraAn experiment was carried out to evaluate the dry matter production, total dry matter availability, daily dry matter accumulation rate, light interception, leaf area index, daily accumulation rate, dry matter availability of the morphological components (leaf blades, stems + sheaths and dead material), leaf/stem ratio, crude protein, neutral detergent fibre and acid detergent fibre of Faixa-Brancagrass under se...
Regional composition of carcass and tissue composition of cuts from lambs slaug...
Andrade, Ana Carla Santana; Macedo, Francisco de Assis Fonseca de; Santos, Gladston Rafael de Arruda; Queiroz, Larissa de OliveiraThe aim of this study was to evaluate the influence of the subcutaneous fat thickness (SFT) on the regional composition of the carcass, the tissue composition of cuts, and the leg muscularity index of Santa Inês lambs. This experiment involved 24 uncastrated male lambs at approximately 100 days of age and at an average live weight of 22.70 ± 3.75 kg that were kept in the feedlot, where they received a complete ...

Campos, Roseane Nunes de Santana; Bacci, Leandro; Araújo, Ana Paula Albano; Blank, Arie Fitzgerald; Arrigoni-Blank, Maria de FátimaArtigo de revisão; O carrapato bovino Riphicephalus microplus (Acari: Ixodidae) constitui um dos grandes problemas enfrentado pelos pecuaristas de várias partes do mundo. No Brasil este ectoparasita causa grandes prejuízos à bovinocultura devido ao processo de hematofagia e pela transmissão de agentes patogênicos nos animais hospedeiros. Diante dessa situação os produtores normalmente aplicam carrapaticidas org...
Parâmetros da fisiologia reprodutiva e utilização de hormônios na sincronização...
Pereira, Mikaele Alexandre; Santos, Anselmo Domingos Ferreira; Menezes, Madalena Lima; Carvalho, Camila Thiara Gomes; Santos, Gladston Rafael de ArrudaO objetivo dessa revisão é apresentar informações sobre os aspectos fisiológicos e de manejo reprodutivo de fêmeas leiteiras, abordando os avanços da técnica de sincronização do ciclo estral para inseminação artificial em tempo fixo (IATF) e seu impacto na eficiência reprodutiva em bovinos de leite. Fêmeas bovinas leiteiras normalmente apresentam baixa eficiência reprodutiva, impossibilitando a obtenção de um I...
