Enhancement of the CDC ovitrap with hay infusions for daily monitoring of Aedes aegypti populations.
An ovitrap containing hay infusion and a second ovitrap adjacent to it containing a 10% dilution of the infusion in tap water together yielded 8 times more Aedes aegypti eggs than single CDC ovitraps containing tap water. These "enhanced pairs" were significantly more attractive than pairs with other combinations of infusion, water or methyl propionate, and have proven useful for daily monitori...

Most cases may be partially, and many completely relieved, while a fair proportion may be altogether cured ; it is imp...
متن کاملLactational responses to postruminal infusions of amino acids in dairy cows fed maize silage, hay or grass silage.
Duodenal infusions of methionine and ly-sine have been shown to increase milk protein yield in dairy cows given a dehydrated maize diet (Rulquin, 1987). As du-odenal amino acids (AA) profiles vary according to diet (Le Henaff, unpublished), a trial was undertaken to test the lactational responses of dairy cows to methionine and lysine infusions with 3 other diets based on either maize silage (M...
متن کاملHay Preservatives
Alfalfa is usually wilted 15% or less moisture prior to baling for hay. However, harvesting at low moistures increases loss of leaves (protein) during baling and reduces nutritive value. In addition, long wilting times increases the risk for damage from rain. In order to retain more nutrients and prevent rain damage, hay can be baled at higher moistures but the risk of spoilage from undesirable...
متن کاملEffects of a Bacterial Hay Preservative (Pediococcus pentosaceus) on Hay under Experimental Storage Conditions.
The abundant growth of molds and thermophilic actinomycetes in stored hay decreases its quality and can be hazardous for the producer who inhales these contaminants when the moldy hay is fed in closed barns. These microbes are responsible for a respiratory disease called farmer's lung. Products, including bacterial cultures that can be inoculated in hay, are available to prevent hay deteriorati...
