Apparent digestibility of dry matter, organic matter, protein and energy of native Peruvian feedstuffs in juvenile rainbow trout (Oncorhynchus mykiss)
Ortiz Chura, Abimael; Pari Puma, Ruth Milagro; Rodríguez Huanca, Francisco Halley; Ceron Cucchi, Maria Esperanza; Araníbar Araníbar, Marcelino Jorge (BioMed Central, 2018)Trout production is a growing activity in recent years but requires new alternative sources of feed to be sustainable over time. The objective of this research was to determine the apparent digestibility coefficient (ADC) ... -
Changes in hematological, biochemical, and blood gases prameters in response to progressive inclusion of nitrate in the diet of Holstein calves
Ortiz Chura, Abimael; Marcoppido, Gisela Ariana; Gere, José; Depetris, Gustavo; Stefañuk Bahamonde, Francisco José; Trangoni, Marcos David; Cravero, Silvio Lorenzo Pedro; Faverin, Claudia; Cataldi, Angel Adrian; Ceron Cucchi, Maria Esperanza (Veterinary World Publisher, 2021-01)Background and Aim: Nitrate (NO3-) reduces enteric methane emissions and could be a source of non-protein nitrogen in ruminant feeds. Nonetheless, it has a potential toxic effect that could compromise animal health and ... -
Ciliate protozoa of the forestomach of llamas (Lama glama) from locations at different altitude in Argentina
Ceron Cucchi, Maria Esperanza; Marcoppido, Gisela Ariana; Morici, Gabriel Edgardo; Cravero, Silvio Lorenzo Pedro; Dekker, Anna; Fondevila, Manuel; De La Fuente, Gabriel (2016)This study describes the diversity and concentration of the protozoal population from the forestomach of llamas in Argentina at three altitudinal locations. Protozoal diversity was studied in samples from eight llamas from ... -
Dynamics of the ruminal microbial ecosystem, and inhibition of methanogenesis and propiogenesis in response to nitrate feeding to Holstein calves
Ortiz Chura, Abimael; Gere, José; Marcoppido, Gisela Ariana; Depetris, Gustavo; Cravero, Silvio Lorenzo Pedro; Faverin, Claudia; Pinares-Patiño, Cesar; Cataldi, Angel Adrian; Ceron Cucchi, Maria Esperanza (Elsevier, 2021-12)It is known that nitrate inhibits ruminal methanogenesis, mainly through competition with hydrogenotrophic methanogens for available hydrogen (H2) and also through toxic effects on the methanogens. However, there is limited ... -
Enteric methane emission from Sheep fed with rhodes grass hay (Chloris gayana) alone or supplemented with dried distillers’ grains with solubles
Gere, José; Feksa Frasson, Mónica; Wawrzkiewicz, Marisa; Fernández Pepi, María Gabriela; Ramos, María Laura; Bualo, Ricardo Alberto; Ceron Cucchi, Maria Esperanza; Jaurena, Gustavo (MDPI, 2022-09)Livestock systems based on subtropical and tropical pastures are characterized by the low productivity of livestock due to the poor nutritional value of the forage (low nitrogen concentration and digestibility, and high ... -
Improving the accuracy of beef cattle methane inventories in Latin America and Caribbean countries
Congio, Guilhermo F.S.; Bannink, André; Mayorga, Olga L.; Rodrigues, João P. P.; Bougouin, Adeline; Kebreab, Ermias; Carvalho, Paulo C.F.; Berchielli, Telma T.; Mercadante, Maria E.Z.; Valadares-Filho, Sebastião C.; Borges, Ana L. C.C.; Berndt, Alexandre; Rodrigues, Paulo H.M.; Ku-Vera, Juan C.; Molina-Botero, Isabel C.; Arango, Jacobo; Reis, Ricardo A.; Posada-Ochoa, Sandra L.; Tomich, Thierry R.; Castelán-Ortega, Octavio A.; Marcondes, Marcos I.; Gómez, Carlos; Ribeiro-Filho, Henrique M.N.; Gere, Jose Ignacio; Ariza-Nieto, Claudia; Giraldo, Luis A.; Gonda, Horacio; Ceron Cucchi, Maria Esperanza; Hernandez, Olegario; Ricci, Patricia; Hristov, Alexander N. (Elsevier, 2023-01)On-farm methane (CH4) emissions need to be estimated accurately so that the mitigation effect of recommended practices can be accounted for. In the present study prediction equations for enteric CH4 have been developed in ... -
Isolation of Pseudobutyrivibrio ruminis and Pseudobutyrivibrio xylanivorans from rumen of Creole goats fed native forage diet
Grilli, Diego Javier; Ceron Cucchi, Maria Esperanza; Paez Lama, Sebastián Antonio; Egea, Angela Vanina; Schnittger, Leonhard; Cravero, Silvio Lorenzo Pedro; Sosa Escudero, Miguel Angel; Allegretti, Liliana Inés; Arenas, Graciela Nora (Springer, 2013-09)We isolated and identified functional groups of bacteria in the rumen of Creole goats involved in ruminal fermentation of native forage shrubs. The functional bacterial groups were evaluated by comparing the total viable, ... -
Llama and sheep ruminal fluid digestive capacity by in vitro gas production technique
Ortiz Chura, Abimael; Wawrzkiewicz, Marisa; Cravero, Silvio Lorenzo Pedro; Fernández Pepi, María Gabriela; Ceron Cucchi, Maria Esperanza; Jaurena, Gustavo (Wiley, 2022-03)BACKGROUND: The in vitro gas production technique has been used to evaluate forage fermentation kinetics. However, individual and animal species variation can change fermentation patterns due to differences in ruminal ... -
On the use of the SF6 gas tracer technique in Latin America for measuring methane emissions in ruminants : a review and analysis
Loza, Cecilia; Ceron Cucchi, Maria Esperanza; Cabezas-Garcia, Edward Hernando; Ortiz Chura, Abimael; Gualdrón-Duarte, Laura; Gere, Jose Ignacio (Taylor and Francis, 2024)The SF6 gas tracer technique is extensively used to measure enteric CH4 emissions for scientific research in Latin-American countries. Although guidelines on how to properly implement this technique have been published, ...
