Item Custo-benefício do uso de suplemento mineral injetável “off-label” em fêmeas zebuínas antes do início da estação de monta visando incrementar retorno financeiro(Universidade Brasil, 2024) Farto, Brígida Gabriela de Jesus Sales Sousa; Bertipaglia, Liandra Maria Abaker; Orlandi, Cássia Maria BarrosoNutrition directly influences the fertility of bovine females, as well as the survival of the embryo, in addition to ensuring, postpartum, an adequate body score for the female to return to reproduction. Reproductive performance intensely influences the revenue of beef cattle production systems and must be managed rationally. The objective was to evaluate the cost-benefit and reproductive performance of Nelore zebu heifers and primiparous heifers submitted to “off-label” injectable mineral supplementation, before implementing the Fixed Time Artificial Insemination (IATF) protocol. The experiment was carried out on a rural property, in the municipality of Alto Alegre dos Parecis, state of Rondônia. Heifers and primiparous cows were grazed in paddocks with Urochloa Brizanta grass and Big Cromo Cria mineral salt supplementation. The two groups (heifers and primiparous cows) were divided into treatment subgroups (57 heifers and 75 primiparous cows received injectable mineral mixture supplementation, and 51 heifers and 88 primiparous cows did not receive injectable mineral mixture supplementation). The injectable mineral mixture used was the commercial product Fosfosal® Virbac, at a dose of 10 mL, applied intramuscularly, 30 days before the TAI program. Injectable mineral supplementation in “off-label” Nelore cattle, both primiparous and heifers, did not demonstrate a significant effect on increasing the pregnancy rate. And the economic results reaffirm that this practice does not contribute to optimizing economic efficiency and profitability of calf production in these categories.Item Qualidade da carne suína: distância e tipo de transporte no pré-abate(Universidade Brasil, 2022) Coelho, Angelo Rodney da Rocha; Melo, Gabriel Maurício Peruca de; Bertipaglia, Liandra Maria AbakerConsumer demand in relation to food quality has been a determining factor in the purchase of food by the world's population. Constantly, the consumer has been looking for safe products and nutritional quality, linked to economic value and purchasing power. The pre-slaughter aspects, including transportation, are decisive factors for the final quality of pork. Animals submitted to stress effects from the time of departure from the farm of origin until the time of slaughter will present quality deviations in the final product. In this context, with the objective of determining the effects of the distance from the farm to the slaughterhouse and the type of vehicle transporting the animals to be slaughtered on the final quality of pork meat, a study was conducted in a slaughterhouse located in the State Inspection Service - SIE in the central region of the State of Rondônia (RO), with a daily slaughter capacity of 120 animals. For that, fifteen animals were selected from 2 sample lots of pigs with the same age, slaughter weight and lineage in two realities in relation to distance and type of transport vehicle (Lot 01/Mato Grosso, 1,008 km away from the slaughterhouse transported with specific trailer for the transport of swine with a transport time of 21 hours and, Lot 02/Rondônia, 125 km away from the slaughterhouse, transported in a cage-type cattle trailer for the transport of cattle, with a transport time of 3.5 hours). After carrying out the in loco and laboratory analyzes (hot and cold carcass weight, pH, color, water retention capacity, weight loss by cooking), it was found that there was a higher incidence of DFD meat in animals transported for a long time even using specific transport for swine. Thus, it was concluded that the distance/time of transport is the main factor during pre slaughter management in relation to the quality of pork.Item Rinotraqueíte infecciosa, mamilite e diarreia viral bovina em rebanhos de Humaitá/AM(Universidade Brasil, 2018) Laner, Diego; Soares, Vando Edésio; Orlandi , Cássia Maria Barroso
