In vitro evaluation of microencapsulated organic acids and pure botanicals as a supplement in lactating dairy cows diet on in vitro ruminal fermentation
(2023)The utilization of microencapsulated organic acids and pure botanicals (mOAPB) is widely used in the monogastric livestock industry as an alternative to antibiotics; in addition, it can have gut immunomodulatory functions. ... -
Can dietary magnesium sources and buffer change the ruminal microbiota composition and fermentation of lactating dairy cows?
(2023)Magnesium oxide (MgO) is one of the most used Mg supplements in livestock. However, to avoid relying upon only one Mg source, it is important to have alternative Mg sources. Therefore, the objective of this study was to ... -
Effects of cashew nut-shell extract and monensin on microbial fermentation in a dual-flow continuous culture
(2023-09-09)The objective of this study was to compare cashew nut-shell extract (CNSE) to monensin and evaluate changes in in vitro mixed ruminal microorganism fermentation, nutrient digestibility, and microbial nitrogen outflow. ... -
In vitro evaluation of Lactobacillus plantarum as direct-fed microbials in high-producing dairy cows diets
(2019-12-21)The objectives of this study were: 1) to compare the effects of live yeast (LY), yeast fermentation product (YFP), a mix of Lactobacillus acidophilus and Propionibacterium freudenreichii (MLP), and Lactobacillus plantarum ... -
Valorization of cow manure: Unraveling bacterial community changes driven by vermicomposting and their impact on vermicompost tea production
(2023)Vermicomposting is utilized to valorize agricultural residues, including excess manure from dairy farms. The microbiome diversity of vermicompost contributes to its numerous beneficial characteristics. However, it remains ... -
Composición de la comunidad, estructura poblacional y condición reproductiva de roedores en una granja avícola de Costa Rica
(2018)Rodents are usually part of livestock production systems. Due to the negative impact they caused it is necessary to implement control programs by determining the species and population status. We studied the rodent ... -
Identification of Pseudococcus viburni and Pseudococcus longispinus (Hemiptera: Pseudococcidae) in Musa sp.
(2018)To establish appropriate taxonomic relationships in studies of mealybugs it is necessary to study the insects by two techniques: morphological and molecular. The aim of this research is to study mealybugs (Hemiptera: ... -
Effects of Toasting Time on Digestive Hydrolysis of Soluble and Insoluble 00‑Rapeseed Meal Proteins
(2017-02-11)Thermal damage to proteins can reduce their nutritional value. The effects of toasting time on the kinet ics of hydrolysis, the resulting molecular weight distribu tion of 00-rapeseed meal (RSM) and the soluble and insolu ... -
Processing temperature and sugar type affect the rate and the extent of proteolysis of a model soy protein isolate system
(2020-11)Processing of ingredients and diets using hydrothermal treatments can lead to negative effects on the nutritional value of proteins, depending on the processing conditions and the matrix of the ingredient or diet. The ... -
Of proteins and processing Mechanisms of protein damage upon rapeseed processing and their effects on nutritional value
(2017-01-31)Amino acids are crucial for livestock animals, primarily obtained from the protein fraction of plant ingredients in their diets. However, the hydrothermal processing of protein-rich co-products from the vegetable oil ... -
Copper sulfate and sodium selenite lipid-microencapsulation modifies ruminal microbial fermentation in a dual-flow continuous-culture system
(2020-08)Undesirable interactions between trace mineral ele ments and ruminal contents may occur during digestion when mineral salts are supplemented. Antimicrobial effects of copper sulfate (CuSO4) may affect ruminal digestibility ... -
Inmunocompetencia y estado nutricional de terneras de lechería alimentadas con calostro retrovirus-positivo: estrategias para mejorar la transferencia pasiva
(2023)Cuarenta terneros (29 hembras y 11 machos) fueron asignados sistemáticamente a uno de dos grupos, como sigue: [1] suministro de 1,8 L de calostro materno o 171 g de IgG (grupo CM o A1, n=20) y [2] suministro de 1,5 L de ... -
Perceptions of Whether Stereotypic Off-the-Track Thoroughbreds are Harder to Rehome Than Nonstereotypic OTTBsdA Pilot Survey Study
(2019)Several studies have indicated higher incidence of stereotypic behaviors (STBs) in Thoroughbreds. The aftercare of Off-the-Track Thoroughbreds (OTTBs) has received increased attention in the last decade; however, research ... -
Physical and chemical changes of rapeseed meal proteins during toasting and their effects on in vitro digestibility
(2016)Background: Toasting during the production of rapeseed meal (RSM) decreases ileal crude protein (CP) and amino acid (AA) digestibility. The mechanisms that determine the decrease in digestibility have not been fully ... -
