Persistent anthelmintic activity of topically administered ivermectin in red deer (Cervus elaphus L.) against lungworms (Dictyocaulus viviparus)     

S. Rehbein  M. Visser 《New Zealand veterinary journal》2013,61(3):85-87

A controlled trial was conducted to evaluate the persistent anthelmintic effect of ivermectin as a topical treatment at 500 μg/kg against induced infection with lungworm (Dicryocaulus viviparus) in red deer (Cervus elaphus). The results showed a highly significant (p < 0.01) anthelmintic activity for at least 28 days against a newly acquired infection with Dictyocauus viviparus (> 99% efficacy).  相似文献

'Looking up' behavior in the holding area of the milking parlor: its relationship with step-kick, flight responses and productivity of commercial dairy cows     

Toshie ISHIWATA  Katsuji UETAKE  Robert J. KILGOUR  Toshio TANAKA 《Animal Science Journal》2005,76(6):587-593

Commercial dairy cows milked in a parlor system are packed close together in the holding area before milking. The present study examined the relationships of ‘looking up’ behavior with some other behaviors and the productivity of 1116–1153 cows from five farms. The individual identities of the cows looking up in the holding area were recorded at 5 min intervals during six intermittent afternoon milking sessions. Entrance into the milking parlor and the numbers of steps and kicks by cows while the milking person was attaching the milking cups, were recorded in six milking sessions. Flight responses in the pasture after milking were recorded over four days intermittently. The frequency of ‘looking up’ behavior weakly, but significantly correlated with flight starting distance (r = 0.10, P < 0.05), while the correlation with the number of step‐kicks during milking was not significant. As for productivity, lactation number (r = ?0.18, P < 0.001), milk yield (r = ?0.15, P < 0.001) and fat content (r = ?0.15, P < 0.001) were negatively correlated with the frequency of ‘looking up’ behavior. Age of cows was correlated with the frequency of ‘looking up’ behavior as well as lactation number (r = ?0.21, P < 0.001). Entrance order was positively correlated with the frequency of ‘looking up’ behavior (r = 0.15, P < 0.001). The ‘looking up’ behavior was observed more frequently in cows in their third or less lactation compared with cows which were in their fourth or greater lactation (P < 0.05). The lactation number of cows was correlated with their milk yield (r = 0.36, P < 0.001) and flight starting distance (r = ?0.21, P < 0.001). In conclusion, ‘looking up’ behavior shown by cows in the holding area before milking might be an indicator of low motivation for milking, mainly because of fear of humans, and an aversion to milking caused by insufficient experience in being milked.  相似文献   

Considerations on ethics and animal welfare in extensive pig production: Breeding and fattening Iberian pigs     

M.A. Aparicio Tovar  J.D. Vargas Giraldo 《Livestock Science》2006,103(3):237

The extensive pig production in Spain is traditionally characterised by: the use of the Iberian pig, an autochthonous breed perfectly integrated into the environment in which they have developed; a long duration of the productive cycle for about 23–24 months; a high level of animal welfare level, specially in the fattening process with freedom of movement and feeding base on natural sources: acorns and grass, and an equilibrated “dehesa” agro-forestry system where this activity has been developed. Nowadays, the introduction of more intensificated methods due to the increasing demand led to important changes, such as: the shortening of the productive cycle (10–12 months); freeing from the territorial base; changes during the fattening period, fattening with mixed feed and less animal freedom. All these facts may implicate a loss of the animal welfare condition. These circumstances lead us to question it from an ethical point of view.  相似文献

运用图书馆公益性服务地方志编写     

秦翠萍 《农业图书情报学刊》2009,21(5):179-180

图书馆永远是一种公益性文化教育机构。图书馆及其藏品作为一种公共物品，靠全民税收由政府兴办；图书馆作为一种知识实体，不可能全面实行有偿服务；图书馆作为向公众提供知识载体的场地之一，也不可能靠自身的知识劳务输出完善自我生存与发展。  相似文献
