Efficiency of water use and nitrogen for goat milk production in irrigated pasture to different management Arq. Bras. Med. Vet. Zootec.
Cavalcante,A.C.R.; Santos,P.M.; C. Júnior,J.A.A.; Cândido,M.J.D.; Lemos,N.L.S..
ABSTRACT The aim was to determine the efficiency of use of water and nitrogen for forage production and goat-milk production on an irrigated Tanzania Guineagrass (Panicum maximum cv. Tanzânia) pasture subjected to different management practices. The management levels tested were combinations among nitrogen fertilization levels and post-grazing residual heights (ResH): Intensive (ResH = 33.0cm and 600.0kg N/ha.year-1); Moderate (ResH = 47.0cm and 300.0kg N/ha.year-1); Light (ResH = 47cm and 0kg N/ha.year-1); and Conventional (ResH = 33cm and 0kg N/ha year-1). The efficiency of water use for forage production was higher in intensive and Moderate management. The Conventional management was recommended only for forage production since there is no nitrogen...

Risk factors for infection by Toxoplasma gondii in herds of goats in Ceará, Brazil Arq. Bras. Med. Vet. Zootec.
Cavalcante,A.C.R.; Carneiro,M.; Gouveia,A.M.G.; Pinheiro,R.R.; Vitor,R.W.A..
In order to identify possible risk factors for T. gondii infection in goat herds in Ceará, Brazil, 2362 serum samples were tested by ELISA. The serological prevalence was 25.1%. The risk factors identified for Toxoplasma gondii infection in goat herds were age, number of cats, use of wooden feeding troughs and absence of feeding troughs. Goats older than 37 months had 2.01 (CI 95%; 1.55 - 2.61) higher risk of infection than younger animals. Greater risk of infection was observed in farms with more than 10 cats (OR = 1.73; CI 95%; 1.01 - 3.33). The use of wooden feeding troughs represented a high probability of infection (OR = 7.81; CI 95%; 1.66 - 36.67). The lack of feeding troughs also represented a high probability of infection (OR = 5.50; CI 95%; 1.24 -...
