Biosystems Engineer, Master's and PhD student in Agricultural Engineering at the Federal University of Campina Grande - UFCG and a Computer Science undergraduate. I study languages such as C/C++ and Python, focusing on applications in IoT, Machine Learning, Computer Vision and Agricultural Automation. I dedicate myself to research in the area of Precision Agriculture and Zootechnics, with an emphasis on Rural Constructions and Ambience. I won the first Manoel Dantas Vilar prize for smart farms, awarded by UFPB. Phone: +55 83 99982-2408

This is an integrative review study oriented by the following guiding question: “What is the scenario of the facilities used in the production of dairy cattle?” The bibliographical research was carried out using the ALICE, BDPA, SciELO, PubMed and SCOPUS databases, with the survey of references being carried out in December 2022 and January 2023, reaching the following quantitative bases: in ALICE of 01 article, in PubMED of 18 articles, SCOPUS 05 articles, totaling a quantity of 24 articles, after application of predetermined inclusion and exclusion criteria. At the end of reading each article, it was possible to organize them into the following categories: Dairy cattle facilities with a focus on housing, bedding, and general handling, and dairy cattle facilities with a focus on ambience and animal welfare; this categorization took place after being observed that 50% of the articles dealt with housing, bedding and handling and 50% dealt with the ambience and animal welfare. All articles selected for the sample corroborate the need for improvements in facilities for dairy cattle to avoid possible damage to animal welfare and unsatisfactory ambience, so that more rigorous systems such as the Tie Stall can be rendered unusable and make room for unconstrained systems such as Free Stall.

A total of 24 native goats, weighing 42 ± 4 kg and 30 ± 3 days into lactation, were used. The data were subjected to canonical analysis to identify the variables that best discriminate. The main objective of this procedure is to find the best set of variables to compose the discriminant function. Four components were needed to explain 70.68% of the total variation in the physical variables and FA profile in the milk of native goats. The percentage of variance accumulated in the first two factors is 41%. The most important variables in the first factor were the short-chain FAs, namely, caproic (6C), caprylic (8C), capric (10C), and lauric (C12), which are responsible for giving the milk its characteristic and even unpleasant odor, depending on their concentration. New studies with a larger sample of data should be carried out to better understand the relationships between physical and chemical variables in the milk of native goats as well as other breeds of goats for comparison. In addition, the weak simple correlations between the variables studied contributed to the results obtained.

The surface temperature was obtained using thermographic images collected in five regions (head, wings, back, legs and crest), calculating the average surface temperature (ST), the gradient between ST and air temperature (AT) and heat emissions by convection and radiation. The experimental design used was entirely randomised, with four treatments and six replications. Surface temperature in all regions of the birds' bodies and ST rose as air temperature rose, and the gradient between ST and AT decreased as AT rose, a fact which can make it difficult for the animals to exchange sensible heat with the environment. The crest and feet had the highest and lowest ST values, respectively. The heat emitted by the birds through convection and radiation decreases as the ambient temperature rises, and of the total heat emitted, there was a predominance of convection.
