Balanço de macrominerais, função renal e metabólitos sanguíneos em ovinos alime...
Silva, Márcia Pereira daThe objective of this study was to evaluate whether the substitution of Buffel grass hay by Opuntia stricta Haw diet affects the balance of macrominerals, kidney function and blood metabolites in sheep. For this purpose, 5 Santa Inês sheep, adult, castrated and cannulated in the rumen, weighing around 61.5 ± 9.5 kg, were distributed in a 5x5 Latin square design for 60 days, divided into 5 periods 12 days. The a...
Utilização de plasma sanguíneo na dieta de frangos de corte
Silva, Luzia Trajano daThe objective was to study the inclusion of pig blood plasma in the diet of broiler chickens from lots of arrays of different ages (36 and 56 weeks), created in recycled litter and high density housing (12 birds / m 2). 6,000 chicks from Cobb ®500 line with one day of age were used. The treatments were arranged in a factorial scheme (2x4), two ages arrays (36 and 56 weeks) and four plasma supply levels (0%, 1.0...
Exigências nutricionais de energia e proteína para mantença e ganho de caprinos...
Souza, Anaiane PereiraThe aim of this study was to determine body composition in Caninde kids, energy and protein requirements for maintenance and growth. In the trial 33 Caninde male castrates were used, averaging 15.62 ± 0.87 kg of BW. A group consisted of five kids was slaughtered as baseline. The remaining kids (n=28) were allocated randomly to seven groups with four levels of feed intake. The levels were: ad libitum, 80%, 60% o...
Variação sazonal na estrutura do pelame e na morfologia da pele de caprinos e o...
Amorim, Mikael Leal Cabral Menezes deThe physical structure of the skin surface of animals are constantly adjusting it in order to provide an optimum combination of skin and fur, which favor the acclimatization in a particular environment. The objective was to evaluate the effects of the change in seasons in low-latitude regions of the hair coat characteristics and morphology of the skin Caninde and Moxotó goats and sheep Morada Nova and Santa Ine...
Substituição do farelo de soja por uréia em dietas a base de capim buffel difer...
Pereira, Gildenia AraújoThis study aimed to evaluate the performance of sheep using diets containing hay buffel grass with levels of urea replacing true protein sources, from the soybean meal in the feeding of lambs in confinement. The experiment was executed at the Fazenda Experimental Pendência Empresa de Pesquisa Agropecuária da Paraíba S.A (EMEPA). Thirty sheep without racial pattern set were used with an average of initial live w...
Comportamento ingestivo de vacas em lactação alimentadas com dietas contendo ta...
Pinheiro, Antonio da CostaThe objective of from this study to evaluate the influence of the inclusion of tannin levels on the ingestive pattern of lactating crossbred cows. We used a 5 x 5 Latin Square design, with 5 tannin levels in the diet (0, 1.3, 2.6, 3.9, and 5.2% on DM basis) and 5 cows crossbred primiparous (Holstein x Zebu) with average weight ±420kg and average production level of ±18 kg / day. The experimental stage was compr...
Padrão histo-anatômico, degradabilidade e compostos secundários em acessos de m...
Silva, Kleitiane Balduino daAnatomical characteristics knowledge, ruminal degradability and forage plants secondary metabolites help to clarify differences in digestibility, especially in species from extreme weather environments, as is the case of Caatinga plants, which may contain structures and different chemicals compounds which limit their digestibility, thus restricting their nutritional value. This study objective was to characteri...
Manipulação térmica embrionária e diferentes níveis de treonina na resposta de ...
Azevedo, Alessandra Reigado Eliezer Gomes deThe effects of thermal manipulation during incubation and dietary threonine levels on Label Rouge birds challenged with Salmonella Enteritidis were assessed in the present study. Two hundred and forty fertile eggs of Naked Neck birds were weighed and distributed in three artificial incubators set to 37.7 ºC and 60% of relative humidity. At the eleventh day of incubation (DE11), the temperature of the incubators...
Transmissão de malária baseada na dinâmica da interação entre mosquitos selvage...
Meneses, Aline Costa deRecent advances in genetic manipulation have made it possible to obtain mosquitoes that are refractory to diseases, so that the transgene that blocks the cycle of the protozoan in the mosquito propagates through its descendants. The study of transgenic mosquitoes is a promising alternative for the reduction of malaria, yet disseminating genes that control a wild mosquito population has been a challenge to this ...
Fitossociologia e composição bromatológica de espécies herbáceas e subarbustiva...
Cassuce, Meiry RodriguesThe study of physiognomy and floristic caatinga generate diagnostics about the current state of pastures which together with other information potential, allow the drafting of strategies for conservation and sustainable use of remnant vegetation. This study aimed to understand the floristic composition and phytosociological parameters of herbaceous vegetation and undergrowth under different goat grazing pressur...
