The effect of insoluble fiber and intermittent feeding on gizzard development, gut motility, and performance of broiler chickens

Abstract

Two experiments were conducted to test the following hypothesis: exposing broiler chickens to coarse insoluble fiber in the diet will result in enhanced gizzard function and performance, improved adaptability to an intermittent feeding program, and an increase in the occurrence of reverse peristalsis. In experiment 1, 102 Ross 308 broiler chickens were either intermittently or ad libitum fed a basal diet, the basal diet diluted with 15% coarse hulls (consisting of equal weights of hulls from oats and barley), or the basal diet diluted with 15% of the same hulls finely ground in a 2 × 3 factorial arrangement with 17 individually caged birds per treatment. Birds fed ad libitum had access to feed continuously for 18 h/d, whereas those on intermittent feeding had restricted access to feed from 7 d of age. From 18 d of age, the restrictive-feeding program consisted of four 1-h meals and one 2-h meal per day. In experiment 2, 156 broiler chickens in 12 pen cages with wood shaving-lined floors were exposed to 1 of 4 treatment groups with 3 pens/treatment: intermittent or ad libitum feeding of a basal diet and intermittent or ad libitum feeding of a coarse hull diet, as described above. At 31 and 32 d of age, birds in experiment 1 were...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
