Examining the perspectives of using manure from livestock farms as fertilizer to crop fields based on a realistic simulation
(Elsevier, 2021-10-13)
Intensive livestock production has a negative environmental impact by producing large amounts of animal dejections, which, if not properly managed, can contaminate nearby water bodies with nutrient ...
Biogas production from slaughterhouse waste: Effect of blood content and fat saponification
(Elsevier, 2021-08-12)
The effect of fat saponification and the inclusion or exclusion of blood in slaughterhouse mixtures were assessed in terms of anaerobic digestion performance. Mixtures of animal by-products (ABP) were ...
Intramuscular vs. Intradermic Needle-Free Vaccination in Piglets: Relevance for Animal Welfare Based on an Aversion Learning Test and Vocalizations
(Frontiers Media, 2021-08-11)

Experimental and field investigations of exposure, replication and transmission of SARS-CoV-2 in pigs in the Netherlands
(Taylor & Francis Open Access, 2021-12-21)
In order to assess the risk of SARS-CoV-2 infection, transmission and reservoir development in swine, we combined results of an experimental and two observational studies. First, intranasal and intratracheal ...
The Optimal Valine to Lysine Ratio for Performance Parameters in Weaned Piglets
(MDPI, 2021-04-27)
The optimal digestible (d) Valine (Val) to d Lysine (Lys) ratio (dVal:dLys) in weaned
piglets was determined using two different regression models. A total of 200 piglets were allotted to
five feeding ...
Selection and application of agri-environmental indicators to assess potential technologies for nutrient recovery in agriculture
(Elsevier, 2021-12-13)
The adverse effects of agriculture and livestock production on the environment are well-known and require mitigation in order to achieve sustainability in the food production chain. This study focused ...
Feeding regimes affected the circadian rhythms of pancreatic digestive enzymes and somatic growth in flathead grey mullet (Mugil cephalus) fry
(Elsevier, 2021-11-14)
The effect of different feeding regimes on the circadian rhythms of pancreatic digestive enzyme activities was evaluated in Mugil cephalus fry weighting 0.34 ± 0.01 g. Feeding regimes (feeding ration = ...
