Abstract: he irregularity of rainfall and low winter temperatures are limiting factors for forage productivity. Irrigation can be used to minimize these interferences. Therefore, this research aimed to evaluate the productive characteristics of the genus Cynodon spp. cv. Tifton 85, with and without irrigation, in the four seasons of the year. The experiment was carried out from february 20, 2020 to february 20, 2022, in the Irrigation and Drainage area of the Federal University of Grande Dourados. The experimental design was in randomized blocks with a 4x4 factorial scheme, with 4 replications, in which factor 1 is the seasons of the year (autumn, winter, spring and summer), and factor 2 is the combinations between the two years and the irrigation (year 1 with irrigation; year 1 without irrigation; year 2 with irrigation; year 2 without irrigation). The collection cycle was every 28 days, evaluating the total forage productivity, leaf/stalk ratio and height. The best dry matter productivity indices were recorded in year 2 with irrigation, in the spring and summer seasons, with 16.428,5 kg ha-1 and 11,628 kg ha-1, respectively.

Abstract: The use of music as a form of environmental enrichment has been studied in recent years because it is an economically viable resource, that can provide promising results in animal welfare, especially in conditions of intensive confinement. However, little is known about the effects of different musical characteristics on horses. The research was carried out with the objective of evaluating the effects of two styles of classical music, based on different rhythmic tempos (BPM), on the behavior, physiological and blood parameters of horses during social isolation and restriction of movements. Two experiments were carried out, the first of which, lasting 27 days, used nine mixed breed horses, distributed in a Greco-Latin square design in three treatments (Control, Slow Rhythm (63 to 83 BPM) and Moderate Rhythm (75 to 107 BPM)). For social isolation and restriction of movement, the animals were daily placed in individual stalls for two hours, being exposed to the stimuli for 60 minutes, and their behavior, eye temperature, heart and respiratory rates were evaluated. Exposure to moderate-tempo music promoted an increase in eye temperature and a decrease in heart rate, while the slower musical stimulus administered to horses reduced respiratory rate during exposure. In the second experiment, carried out thirty days after the end of the first one, ten horses of mixed breed were used, distributed in a completely randomized design in the treatments: Slow Rhythm (63 to 83 BPM) and Moderate Rhythm (75 to 107 BPM), being exposed to music for seven days in a row for one hour, while confined. The results were higher calcium levels, higher level of corpuscular hemoglobin (MCH) and total hemoglobin concentration, in addition to the reduction of lymphocytes. In contrast, exposure to slow music only promoted an increase in HCM, hemoglobin concentration and reduction in the average size of platelets, however, both songs led to a significant increase in serotonin levels after one week of exposure. Exposure to different musical rhythms promoted different responses, both of which were contributing in the promoting the well-being and health of stabled horses

Abstract: This dissertation is presented in 2 chapters, being a literature review and field research. Chapter 1: The objective of the literature review was to elucidate the main advances related to the use of natural zootechnical additives, including tannins, listing the ability to promote nutrient absorption, improvement in intestinal villi and immune status of birds, contributing to production and quality of eggs. These natural compounds can play a crucial role in improving bird performance and health. Furthermore, tannins act as natural antioxidants, protecting biomolecules against damage caused by free radicals. This antioxidant action is essential to prevent lipid oxidation, which is one of the main causes of quality loss in poultry products. Chapter 2: The study was conducted with the objective of evaluating the effect of different levels of plant extract based on hydrolyzable tannin in the diet on performance, egg quality, intestinal health, lipid profile and antioxidant potential of egg yolks. Japanese quails. Furthermore, evaluate the effects of the plant extract based on hydrolysable tannin on egg quality, lipid profile and antioxidant potential of the yolk of quail eggs stored for up to 28 days. The study was carried out in the experimental aviary for laying birds, in the facilities intended for coturniculture at the Faculty of Agricultural Sciences of UFGD, in the municipality of Dourados, Mato Grosso do Sul, lasting 56 days, using a flock of 324 Japanese quails (Coturnix coturnix japonica) at peak laying. The birds were distributed in a completely randomized design into six treatments with the inclusion of plant extract based on hydrolyzable tannin at six levels: Control, 250, 500, 750, 1,000 and 1,250 g/ton, with nine replications and 6 quails per experimental unit. . Productive performance, egg quality, organ biometry, blood biochemical profile, intestinal histomorphometry, lipid profile and antioxidant potential of the yolk were evaluated. An egg storage test was carried out for 28 days, evaluated weekly. Tannic acid-based hydrolyzable tannin supplementation did not affect the performance, organ health, blood biochemical parameters or intestinal morphometry of Japanese quails in the study. Egg quality was not harmed by the inclusion of 250 g/ton of hydrolyzable tannin, and even with maximum inclusion, egg quality remained satisfactory. The addition of hydrolyzable tannin resulted in an increase in unsaturated fatty acids and improved the ratio between unsaturated and saturated fatty acids in egg yolk. This contributed to a healthier lipid profile in eggs. Furthermore, the inclusion of hydrolyzable tannin increased the antioxidant potential of egg yolks, suggesting benefits for lipid stability and consumer health

Abstract: In dairy cattle farming, the strong interaction between humans and animals, especially during milking management, can directly influence well-being and aspects related to production. In this context, good management practices, combined with the use of tactile and auditory stimuli, can help achieve better results. Therefore, the objective of this study was to evaluate the effects of desensitizing massage and musical stimuli during milking on productive, physiological, sanitary, and welfare parameters of dairy cows. The experiment was conducted on a commercial farm characterized by low milk production. Forty crossbred dairy cows, ranging in age and body weight from 36 to 42 months and 350 to 400 kg, were randomly allocated in a 2x2 factorial design to the following treatments: (Con) - cows not exposed to stimuli; (Mas) - cows exposed to massage during milking; (Mus) - cows exposed to music during milking; (Mas+Mus) - cows exposed to both stimuli during milking. Classical music with Andante (75 to 107 BPM) and Andante Moderato (90 to 100 BPM) tempos was selected for the study, and the massage was performed on the back and udder of the females immediately after entering the milking parlor. The experiment lasted for 39 days, with the first 10 days for animal adaptation and 29 days for data collection after the introduction of sensory stimuli. Cows not exposed to any stimuli showed residual milk quantity up to 41% higher than those that received only one of the stimuli or both combined. The use of massage during milking increased respiratory rate, milking time, and subclinical mastitis scores. Cows exposed to Mas+Mus showed higher ocular temperature compared to those that received only massage, as well as shorter flight distance compared to the other treatments. The sound stimulus increased pre-milking milk dripping. Cows that received the stimuli had higher levels of serotonin, indicating an additive effect of environmental enrichment factors. The use of desensitizing massage and music during milking was effective in reducing cows' reactivity to humans and promoting improvements in well-being and productivity. Both techniques, when combined, can have additive effects on milk productivity; however, certain sanitary precautions must be taken regarding the equipment used for tactile stimuli.
