“…This may have been due to the larger group sizes and total numbers in trial 1, or the adverse weather of trial 2. The midnight eating observed when the nights were long is consistent with the report of Wilson and Flynn (1979). Christopherson (1973) did not observe a midnight eating period in a study conducted in Edmonton even when daylight was less than 8 h, but many of the cattle were on restricted feed or high concentrate diets, and that could have reduced eating time.…”

“…Continuous observations involve fewer animals but are essential to study events or short duration behaviors (Lehner, 1979;Mullen et al, 1980). Although eating patterns of feedlot cattle are known to be associated with daylength (Ray and Roubicek, 1971;Hoffman and Self, 1973), reports on the occurrence of a midnight eating period during the extended winter nights in northern latitudes are conflicting (Chris ~ topherson, 1973;Wilson and Flynn, 1979). Concerns for total eating time because of the extremes in daylength in northern areas have been expressed by Wilson and Flynn (1975), and daylength is likely to affect other behaviors as well.…”

The diurnal behavior patterns of feedlot bulls were investigated at 52 degrees N during winter and spring. Two trials were conducted during periods when the daylight portion of the day increased by over 7 h. In trial 1, 324 bulls were observed hourly for 24 h on nine occasions at 2-wk intervals. The average proportions of bulls eating, drinking, standing and lying were 9.8, 1.9, 27.4 and 60.0%, respectively. Major periods of eating, drinking and standing were associated with the times of sunrise and sunset and shifted with seasonal changes. Initiation and termination of the afternoon period of eating was greatly affected by changing times of sunset and not by the daily addition of feed, which always occurred at approximately 1600 h. A significant period of eating, involving up to 15% of the bulls at one time, occurred near midnight during the longer winter night but decreased in duration and intensity as day-length increased. In trial 2, continuous observations for 24 h were made at 2-wk intervals on two groups of nine bulls. When the spread in time between morning and evening activity increased due to longer daylength, bulls were active at midday. This became more pronounced on days when the photoperiod exceeded 10 h. Minor periods of activity were evident at night. Mounting and agonistic encounters increased dramatically in frequency near sunset and in general were associated with the major periods of eating and standing.(ABSTRACT TRUNCATED AT 250 WORDS)

“…O tempo de ócio total não diferiu entre as dietas e a média foi de 10,2 h/dia. Salla et al (2003) verificaram que vacas Jersey apresentaram tempos de ócio de 9,86; 10,38; 9,93 e 10,05 h/dia, respectivamente, para as dietas controle, sebo, gordura protegida e grão de soja, enquanto Mendonça et al (2004) Tabela 3 -Consumo diário de matéria seca por animal (CMS), por 100 kg de peso vivo (CMSPV) e consumo de fibra em detergente neutro, eficiência de ruminação da MS e da FDN de novilhos alimentados com diferentes níveis de silagem de girassol na dieta ruminação total apresentou baixa correlação com teor FDN da dieta (r = 0,3382; P = 0,0037), contrariando relatos de Welch & Hooper (1988) (Wilson & Flynn, 1979;Metz, 1985;Camargo, 1988), os quais relataram que o tempo destinado à ruminação é de aproximadamente oito horas por dia em animais confinados.…”

RESUMO -Estudaram-se os efeitos da substituição na dieta da silagem de milho por silagem de girassol (0, 33 e 66% MS) no comportamento ingestivo de novilhos em confinamento. Utilizaram-se nove novilhos castrados com peso vivo e idade média inicial de 288 kg e 20 meses, respectivamente, pertencentes aos grupos genéticos Nelore, 21/32Charolês (C) 11/32Nelore (N) e 21/32N 11/32C. O delineamento experimental utilizado foi o de blocos ao acaso, com três repetições por tratamento.As dietas testadas foram: 100 % de silagem de milho e 0 % de silagem de girassol; 70,94% de silagem de milho e 29,06 % de silagem de girassol; 38,27 % de silagem de milho e 61,73 % de silagem de girassol, todas com relação volumoso:concentrado 60:40. O tempo destinado ao ócio deitado foi maior para os novilhos que consumiram apenas silagem de milho como volumoso em relação aos que consumiram silagem de girassol. O tempo despendido em ócio em pé foi semelhante entre as dietas com 33 (1,84 hora) e 66 % de silagem de girassol (1,96 hora) e menor para aquela sem silagem de girassol (1,62 hora).O tempo em ruminação dos animais aumentou com a inclusão da silagem de girassol na dieta e correspondeu a 8,61; 8,76 e 9,45 horas, respectivamente, para 0; 33 e 66 % de silagem de girassol. Animais alimentados somente com silagem de milho apresentam maior eficiência de ruminação da matéria seca e da fibra em detergente neutro. O tempo despendido por refeição diminui com o aumento da participação da silagem de girassol.

Nine castrated steers were used, with average 288 kg initial live weight and 20 month old from the Nellore (N), 21/32Charolais (C) 11/32N and 21/32N 11/32C genetic groups. A randomized complete block experimental design was used, with three replications per treatment. The tested diets were: 100% corn silage and 0% sunflower silage; 70.94% corn silage and 29.06% sunflower silage and 38.27% corn silage and 61.73% sunflower silage, all with a 60:40 roughage:concentrate ratio. Time spent lying idle was greater for steers that consumed only corn silage as roughage compared to those that consumed sunflower silage. Time spent standing idle was similar between 33 (1.84 h) and 66% sunflower silage (1.96 h) and lower for 0% sunflower silage (1.62 h). The animals rumination time increased with the inclusion of sunflower on diet, with values of 8.61; 8.76 and 9.45 h, respectively for 0; 33 and 66% sunflower silage.Animals fed only with corn silage show better dry matter and neutral detergent fiber rumination efficiencies. The time spent feeding decrease with higher participation of sunflower silage.

“…Esses resultados são próximos aos valores de 4,6 ± 0,93 horas, 8,04 ± 0,73 horas e 10,1 ± 2,1 horas por dia utilizados nas atividades de alimentação, ruminação e ócio, respectivamente, relatados por diversos autores com vacas leiteiras estabuladas (Ray & Roubicek, 1971;Monty Junior & Garbareno, 1978;Wilson & Flynn, 1979;Metz, 1985;Camargo, 1988;Sahara et al, 1990). Camargo (1988), estudando o comportamento de vacas holandesas confinadas em sistema free stall, no Brasil central, em cinco épocas ao longo do ano, encontrou tempos médios de alimentação, ruminação e ócio de 4,8, 6,8 e 10,4 horas por dia, respectivamente.…”

Pesq. agropec. bras., Brasília, v.34, n.4, p.709-715, abr. 1999 Foram utilizadas 24 vacas da raça holandesa, em diferentes estágios de lactação e níveis de produção, mantidas em dois currais tipo free stall, com ou sem coberturas com lonas plásticas nas extremidades sudeste-noroeste da área coberta. Os parâmetros comportamentais estudados foram: tempos despendidos e freqüências nas atividades de alimentação, ruminação, ócio e procura pelo bebedouro. A proteção da área de descanso dos animais não influenciou as variáveis estudadas. Os tempos despendidos diariamente nas atividades de alimentação, ruminação e ócio foram 3,4, 7,0 e 9,0 horas, respectivamente. As maiores freqüências de alimentação ocorreram antes e depois das ordenhas. A ruminação ocorreu principalmente no período noturno; o ócio foi mais freqüente no período de maior radiação solar. Os animais permaneceram mais tempo na área coberta (13,4 vs 2,5 h/dia). As maiores freqüências de procura pelo bebedouro ocorreram, principalmente, nas horas mais quentes do dia e nos momentos próximos às ordenhas.

BEHAVIOR RESPONSES OF HOLSTEIN DAIRY COWS WITH CONSTANT OR LIMITED ACCESS TO SHADEABSTRACT -The experiment was carried out at Piracicaba, São Paulo, Brazil, from January to February 1993, with the objective of evaluating the behavior responses of Holstein cows, with constant or limited access to shade. The experimental design used was completely randomized. Twenty four dairy cows were used, at different lactation stages and production levels, kept in two free stall barns, with or without protection against solar radiation in south-east and north-west edge. The behavior parameters studied were: alimentation, rumination, rest time and frequency and water ingestion frequency. The protection of the free stall barn didnt affect the behavior responses. The alimentation, rumination and rest time, daily, were 3.4, 7.0 e 9.0 hours, respectively. The highest alimentation frequencies were before and after milking. The rumination was mainly during nocturnal period; the rest was more frequent during the period with higher solar radiation. The animals stayed more time in the shelter (13.4 vs 2.5 h/day). The highest daily water ingestion frequencies were in the hot time and next milking, mainly.
