Evaluación de subproductos de Solanum tuberosum y Daucus carota mediante FES como alternativa en la alimentación animal
The growing demand for foods such as corn or soybeans has favored the implementation of biotechnologies through the use of agro-industrial waste in order to obtain alternative diets with high biological value. For this reason, the objective of this research was to develop a diet based on harvest by-products of potato Solanum tuberosum and carrot Da...
Protein fragment intake and digestibility of protein in diets supplied to Chino Santandereano cattle

Objective. To quantify the concentration and consumption of the protein fragments (NPN, TP, RDTP, SDTP, NDIP, and ADIP) present in the diet supplied to cattle, and its effect on the digestibility of crude protein. Materials and methods. Diets offered to Chino Santandereano cattle in stables, receiving different levels of supplementation, were a...
Milieurisico bestrijdingsmiddelen en veterinaire stoffen in mest via effecten op de voedselketen voor weidevogels
In 2019, a report was issued by Buijs en Samwel-Mantingh which claimed a possible relation between the occurrence of pesticides and veterinary drugs in manure and the decline of farmland birds, which feed on (soil) invertebrates allegedly impacted by these substances. The current research project provides an in-depth analysis of the reliability of ...
Split-feeding en twice a day-feeding voeren bij vleeskuikenouderdieren
In dit rapport worden de resultaten gepresenteerd van een studie naar het toepassen van split-feeding (= apart ochtend- en middagvoer) en twice a day-feeding (standaard voer) t.o.v. eenmaal daags voeren (standaard voer) bij vleeskuikenouderdieren tijdens de late legperiode (van 50 - 60 weken leeftijd). Dit experiment is uitgevoerd in opdracht van h...
309 ASAS-EAAP Talk: Modelling digestion kinetics: the next step in the evaluation of feed ingredients
There is increasing importance of upcycling of low-opportunity-cost feed, food waste, and food processing byproducts into animal products, strongly increasing the variation in the nutritional quality of feed ingredients. Traditionally, feed ingredients are evaluated based on their measured extent of digestion. Increasing awareness that not only the...
Ontwikkeling van een concept voor de bepaling van de gezondheidsstatus van vleeskuikens (onderdeel 2)
In dit rapport worden de resultaten gepresenteerd van de ontwikkeling van een concept voor de bepaling van de gezondheidsstatus van vleeskuikens op bedrijfsniveau. Het doel van het onderzoek was om een methodiek te ontwikkelen waarbij aan de hand van verschillende parameters de gezondheidsstatus van vleeskuikenbedrijven inzichtelijk gemaakt kan wor...
Social and economic impacts of grass based ruminant production
Grass based ruminant production provides multiple benefits to farmers and to wider society. This paper addresses key economic and social factors of grass based ruminant production and illustrates them with national and regional examples from different parts of Europe. Farmers are key actors when it comes to maintaining and improving grass based pro...
Combining grazing and high mineral efficiency
In the Netherlands many farmers assume pasture grazing for dairy cows to be less efficient in terms of mineral utilisation than indoor housing systems. The gross annual grass yield is assumed to be lower as well. Since 2016, Dutch dairy farmers are obliged to use the ANCA-tool (Annual Nutrient Cycling Assessment) to show the mineral efficiency of t...
Determination of effects of some pelletted straws on rumen pH and temperatures with wireless rumen sensors
Published in Revista Mvz Córdoba
Objective. This study was conducted with the aim of determination of the effects of pellets prepared with addition of different additives (molasses, guar meal and sepiolite) on changes in in vitro rumen pH and temperature. Materials and methods. In the current study sixteen pelleted feeds were prepared with wheat and soybean straws. The Daisy incub...
