This research was conducted to evaluate the ingestive behavior and phenotypic plasticity of Girolando heifers subjected to continuous grazing in the semiarid of Pernambuco. Three heifers of 7/8 Dutch-Gir genetic composition were evaluated, submitted to a paddock with 40 x 40 m brachiaria, for 21 days. The meteorological variables recorded in the production environment were the dry, bulb temperature (°C) and the relative humidity of the air (%), which allowed the thermal characterization through the temperature and humidity index (TM). The behavior of heifers was quantified through observation by instantaneous scanning of activities, walking, drinking, eating, ruminating, lying down, leisure and standing. The physiological responses recorded were rectal temperature (°C) and respiratory rate (movement mia-1). The experimental design was completely randomized in a 2 x 3 factorial arrangement (shifts x evaluation period). Behavioral variables were subjected to te chi-square and probability test. The physiological parameters were subjected to analysis of variance and application of the Tukey test at the level of 5% significance. The THI did not exceed 89 units, which characterizes the critical limit of moderate stress for the animals. The heifers proved to be adapted to the climate of the region, as, during the study period, they showed sufficient physiological and behavioral alteration capacity to maintain homoeothermic.Item Proposta de um sistema de produção de leite com dietas à base de palma forrageira(2023-09-11) Melo, Gabriela Correia da Silva; Ferreira, Marcelo de Andrade; http://lattes.cnpq.br/4818123702136736Agreste de Pernambuco is home to the state's main dairy basin, accounting for approximately 75% of production. Due to the edaphoclimatic characteristics of the region (Semi-arid), characterized by low rainfall and high temperatures, challenges related to forage production must be faced in order to sustain dairy production systems in the region. Thus, the implementation of high-yielding roughage can be achieved through appropriate agricultural practices, the use of technologies, the selection of varieties adapted to the region's climate and the adoption of good management practices. In this way, fodder palm has been a valuable option for livestock farming in the Agreste region of Pernambuco, contributing to animal food security during periods of drought and offering a sustainable alternative for feeding livestock in the semi-arid region. The aim was to develop a milk production system with palm-based diets, based on the identification in the literature of the main reference indicators to be improved in order to increase the sustainability of dairy farming in Pernambuco. After identifying them and based on zootechnical indices considered achievable, a stabilized herd was idealized and diets based on fodder palm were calculated to meet the needs of this herd. Subsequently, the reference indices were recalculated and showed a significant improvement, indicating that palm can be an extremely important strategy for daisy fanning in the state.Item Palma forrageira, o alimento mais importante para vacas leiteiras no semiárido pernambucano: manual prático(2022-10-06) Souza, José Felipe Borges de; Ferreira, Marcelo de Andrade; http://lattes.cnpq.br/4818123702136736; http://lattes.cnpq.br/4011173965144301The dairy basin of Pernambuco is distributed throughout its territory, however with a larger concentration in the Agreste region. Evaluations of production systems in this region indicate that milk production becomes efficient over the years, can improve several aspects, among them one of the most important would be the increase in land productivity. This would only be possible, mainly due to the size of the properties, with the implementation of forages with high productivity. In this context, forage palm became a key strategic forage due to its production potential and nutritional value. The objective was to develop a practical manual for the use of forage palm in the diet of dairy cows and to offer the field technician and the producer a material with options to associate it with a range of ingredients normally used in the most practical way possible. From there, 48 diets were formulated, based on forage palm, for cows with different weights (400, 450, 500, 550, and 600 kg) also different milk yields (10, 15, 20, 25, and 30 kg of milk/day). Data were presented on a dry matter basis. It is expected that the material produced can reach the hands of technicians and producers to guide them in choosing the best options according to the characteristics of the production system, availability, and price of ingredients.Item Relatório de Estágio Supervisionado Obrigatório(2022-10-27) Silva, Joás José da; Silva, Valdson José da; http://lattes.cnpq.br/6499654247132691; http://lattes.cnpq.br/6650079186954491Item Relatório de Estágio Supervisionado Obrigatório(2019-07-11) Silva, Erick Alexandre Magalhães; Guim, Adriana; http://lattes.cnpq.br/5179137865818915; http://lattes.cnpq.br/2162720356705857
