Comportamento Ingestivo De Ovinos Alimentados Com Torta De Girassol Oriunda Da Produção De Biodiesel

Abstract: O objetivo deste estudo foi avaliar os efeitos da inclusão de diferentes níveis da torta de girassol sobre o comportamento ingestivo de cordeiros. Utilizaram-se 36 cordeiros mestiços das raças Santa Inês x Dorper alojados individualmente, de forma aleatória, sendo 9 por tratamento, correspondentes ao tratamento controle (0%) e os demais com inclusões ao nível de 5, 10 e 15%. A avaliação do comportamento ingestivo consistiu no registro do tempo gasto com as atividades de ruminação, ócio e alimentação, mediante … Show more

“…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 time of pasture in the early morning did not differ between treatments, this may be linked to the fact that all animals, regardless of treatment, spend the night only with mineral supplement and water available and therefore seek food in a similar way when placed in the area of pasture Monteiro et al (2019) found longer feed intake times in the daytime period and according to Lima et al (2014), the main grazing moments begin at dawn. Usually the pasture activities are interspersed with rumination or idleness periods (Moreira et al, 2018), but because they are stuck in the night period this may have been modified.…”

“…Outro ponto a se observar é a semelhança entre a granulometria do resíduo independente da inclusão na dieta. Monteiro et al (2019) verificaram que a inclusão da torta de girassol nas dietas de ovinos confinados, os teores de FDN aumentaram, contudo não afetou o tempo de ruminação dos animais e ainda observaram que a característica física da fibra da torta de girassol apresentou semelhança em todos os tratamentos, visto que a torta de girassol e o feno de Tífton foram finamente moídos para serem misturados ao concentrado, formando uma mistura completa. Além dos teores de FDN, teores mais elevados de EE na ração podem afetar a ruminação dos animais, principalmente pela redução da taxa de degradação da fibra (Silva et al, 2011).…”
