“…Sousa Segundo, Santos, Souza, Silva, and Souza (2016) observing the behavior of supplemented sheep during 12h of the day, found that rumination occupied about 4.5h of this time. Pazdiora et al (2019) observed cuddling time of 6.10h in sheep fed with Tifton grass presenting 65.4% of ADF and 12% of CP, the animals in the present study presented lower times but the evaluations performed only at the time of pasture (6:00-18:00) disregarded the time used for this activity during the night. Monteiro et al (2019) observed longer time of rumination between 20 and 08h while the feeding periods were higher during the day.…”

The objective was to evaluate the performance and ingestive behavior of grazing sheep in the finishing stage, with supplementation in the period of water restriction. Fifteen male crossbred sheep were used in continuous pasture in Massai grass and supplied supplement formulated with 18% of crude protein in three levels (0.0; 0.3 and 0.6% of body weight), individually. Bromatological and fodder production analyses were performed, as well as foliar mass production, stem mass and senescent material mass. The performance and ingestive behavior of the animals were evaluated. The design was in four randomized blocks for the variables measured in the fodder. For the biometry, weight gain and behavior variables measured in the animals, the design was entirely randomized with five repetitions. The total forage mass production was 5512.41 kg ha-1, with 6.58% of crude protein, 79 38% of neutral detergent fiber and with 65% of foliar mass. The total weight gain and daily weight gain were higher in animals that received a supplement of 0.6% of body weight. In general, the animals grazed more in the morning period and the supplemented ones destined more time for rumination and leisure than the ones not supplemented.

“…This result found for the rumination time can be explained by the supply of hay to the feedlot lambs. According to Pazdiora et al (2019), rumination time is a variable influenced by the nature of the diet, as the higher the fiber content, the greater the time spent on rumination. In Table 3, it is possible to observe that the hay supplied to the feedlot animals presented 684 g kg DM -1 of neutral detergent fiber (NDF).…”

The evaluation of the ingestive behavior of ruminant animals is important to identify the animal response to the particularities of the different production systems. However, the five-minute evaluation technique requires personnel, making it difficult to adhere to farms and research in more complex pastoral systems. Thus, this study objected to evaluating the influence of pasture, silvopastoral, and feedlot production systems on the ingestive behavior of lambs and to defining the behavior recording interval in each of the systems. Twenty-four lambs were distributed in an experimental design in split plots. The plots were the production systems (pasture without shading - PS, silvopastoral - SS, and feedlot systems - FS) and the subplots were the behavior observation intervals (5, 10, 15, and 20 min.). In the pasture without shading and silvopastoral systems, the lambs were kept on Aruana grass (Megathyrsus maximus) pasture and supplemented with concentrate at 1.5% of body weight per day, on a dry matter (DM) basis. In the feedlot system, the lambs received a diet consisting of 200 g kg DM-1 of annual ryegrass hay (Lolium multiflorum Lam.) and 800 g kg DM-1 of concentrate. There was no interaction (P > 0.05) between the production system and the recording interval of behavioral activities. The time spent on food intake was higher (P < 0.05) in the pasture (533 min d-1) and silvopastoral (513 min d-1) systems than in the feedlot (225 min d-1). In contrast, for water intake, time was higher (P < 0.05) in the feedlot (21 min d-1) and lower in the silvopastoral system (5 min d-1). There was no difference (P > 0.05) between the systems for rumination and idle activities, of which daily averages were 378 and 587 min d-1, respectively. There was also no difference (P > 0.05) between the observation intervals for feed, water, rumination, and idleness activities. Lambs in pasture-based systems spend more time feeding, and feedlot lambs spend more time ingesting water. Feedlot lambs ruminate as much as grazing animals when fed hay, even though hay represents only 20% of the total diet. The recording interval of behavioral activities in these production systems can be up to 20 minutes.

“…Já o teor de CNF foi estimado pela equação: 100 -(PB+EE+MM+FDN). O método de ácido sulfúrico 72% p/p foi empregado para determinar lignina "Klason" (Silva & Queiroz, 2002 Pazdiora et al (2019), avaliaram diferentes resíduos de frutas (casca e coroa do abacaxi, semente de acerola, casca de maracujá e semente de cupuaçu) e uma dieta controle (feno de tifton), na proporção de 75% da dieta de ovinos confinados. Os autores verificaram que o CMS foi maior (P<0,0001) para os ovinos que receberam resíduo de maracujá (1170,6g dia -1 ), seguido do tratamento com feno de tifton (962,7g dia -1 ), e apresentou efeitos sobrepostos para o resíduo de abacaxi (693,8g dia -1 ), acerola (644,2g dia -1 ) e cupuaçu (452,9g dia -1 ), e justificaram estes resultados pela composição diferente das dietas.…”

Objetivou-se avaliar os níveis de sementes de cupuaçu em substituição ao grão de milho (0; 25; 50; 75 e 100%) na alimentação de ovinos, sobre o desempenho e digestibilidade das dietas. Os 20 ovinos machos, idade de 10±1 meses, receberam, durante 56 dias, dietas compostas por feno de tifton, farelo de soja, ureia, minerais e grão de milho (60% da matéria seca da dieta) sendo substituídos por sementes de cupuaçu, conforme os níveis. Os animais foram confinados em baias individuais e receberam a dieta a vontade, duas vezes ao dia, preconizando 10% de sobras. O delineamento foi inteiramente casualizado e os dados submetidos à análise de variância, contrastes polinomiais e análise de regressão, ao nível de 5%. O consumo de matéria seca, consumo de proteína bruta, ganho de peso, peso final e digestibilidade da matéria seca reduziram linearmente com o aumento da substituição do grão de milho pela semente de cupuaçu. O consumo de extrato etéreo aumentou linearmente com a substituição do grão de milho pela semente de cupuaçu. O valor da conversão alimentar aumentou com a inclusão da semente de cupuaçu. As digestibilidade do extrato etéreo e da fibra detergente neutro apresentaram efeitos quadráticos. A substituição do milho pela semente de cupuaçu influencia no desempenho de ovinos confinados e na digestibilidade das dietas, mas não comprometeu a terminação dos animais visando o peso de abate.
