The effect of an 18-hour delay in solid feed provisioning on the feed intake and performance of piglets in the first weeks after weaning

open access: yes, 2019
It is generally accepted that early post-weaning feed intake affects post-weaning health and performance. Especially piglets that have not consumed creep feed before weaning have to learn to recognize solid feed.

Small intestine histomorphometry of beef cattle with divergent feed efficiency [PDF]

open access: yes, 2013
BACKGROUND: The provision of feed is a major cost in beef production. Therefore, the improvement of feed efficiency is warranted. The direct assessment of feed efficiency has limitations and alternatives are needed.

Day/night variations of myeloid and lymphoid cell subsets in the murine inguinal lymph node

open access: yesFEBS Open Bio, EarlyView.
The circadian system is involved in the temporal regulation of the immune system. Our study reveals that two innate immune populations, NKT cells and neutrophils, predominate at the beginning of the day in healthy mice, highlighting how the time of day influences immune responses.

Genetics of feed intake and efficiency in grazing dairy cows : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Animal Science [PDF]

open access: yes, 2017
Feed efficiency in dairy cows is widely acknowledged as a highly desirable characteristic to improve because of its well-documented impact on production costs.

Increasing efficiency of a linear-optical quantum gate using an electronic feed forward

open access: yes, 2011
We have successfully used a fast electronic feed forward to increase the success probability of a linear optical implementation of a programmable phase gate from 25% to its theoretical limit of 50%.

Compensation for Uneven Surfaces When Building Laser Deposited Structures [PDF]

open access: yes, 2004
Direct Laser Deposition (DLD) is a blown-powder laser deposition process that can be used to quickly produce, modify or repair fully-dense metallic parts by a layered manufacturing method. However, uneven substrate surfaces often cause variation in the

Effects of aflatoxin B1 on subacute exposure of hybrid groupers (Epinephelus fuscoguttatus♀ × Epinephelus lanceolatus♂): Growth, liver histology, and integrated liver transcriptome and metabolome analysis

open access: yesAnimal Nutrition
With the increasing incorporation of plant-based ingredients into the grouper diet, the issue of aflatoxin B1 (AFB1) contamination in the diet has become a significant concern. In this study, the negative effects of AFB1 on the growth and liver health of

Effects of frequency and period of feeding on growth and feed utilisation in two Asian catfishes, Pangasius bocourti (Sauvage, 1880) and Pangasius hypophthalmus (Sauvage, 1878) [PDF]

open access: yes, 1998
Feeding to satiation in P. bocourti, resulted in higher growth with increased meal frequency. However, growth performance of two-meal or three-meal feeding was not significantly different at all.

dUTPase is essential in zebrafish development and possesses several single‐nucleotide variants with pronounced structural and functional consequences

open access: yesFEBS Open Bio, EarlyView.
dUTPases are involved in balancing the appropriate nucleotide pools. We showed that dUTPase is essential for normal development in zebrafish. The different zebrafish genomes contain several single‐nucleotide variations (SNPs) of the dut gene. One of the dUTPase variants displayed drastically lower protein stability and catalytic efficiency as compared ...
