Resident microbiota habitats and gut-balancing additives for poultry production...
Ribeiro, Apolônio Gomes; Rabello, Carlos Bôa Viagem; Santos, Marcos José Batista dos; Nascimento, Júlio Cézar dos Santos; Silva, Dayane Albuquerque daThe resident microbiota of poultry presents a great variety of commensal and/or mutualistic microorganisms, which colonize from the crop, permeating through the proventriculus, ventricle, small intestine and its portions (duodenum, jejunum, ileum) and large intestine (cecum, colon, and rectum). They act in the metabolism of nutrients in the diet, generating important metabolites for the balance of the intestina...
Methods of analysis of the chemical composition and nutritional value of rumina...
Carvalho, Chrislanne Barreira de Macêdo; Macambira, Gabriel Miranda; Santos, Ana Carolina Ferreira dos; Oliveira, Helia Sharlane de HolandaFeed analysis is one of the main factors observed in animal nutrition. The most efficient way to identify the nutrient content of foods is through the chemical composition and nutritive value. In the analytical quantification of the nutritive value of foods, the main parameters used are: dry matter (DM), oven drying, microwave oven, and toluene distillation methods (silages); mineral matter (MM), high temperatu...
Advances in the subject of prolificacy genes or fertility in sheep: a review
Maciel, Marilene dos Santos; Ribeiro, Apolônio Gomes; Calvacante, Paulo Otávio Silva; Carvalho, Chrislanne Barreira de MacêdoReproductive traits relatively have low or medium heritability and do not exhibit a remarkable response to phenotypic selection. Therefore, the inclusion of genetic information from genes associated with reproductive capacity can efficiently improve the selection response. The main important genes affecting prolificacy and their genetic diversity in different breeds of sheep have been studied on a global scale....
