Interrelationships of Riboflavin and Niacin in Laying Hen Diets

Lipid supplementation of laying hen diets deficient in protein and sulphur amino acids

Dried distillers grains with solubles in laying hen diets.

A study was conducted to test the inclusion rate of corn dried distillers grains with solubles (DDGS) in laying hen diets on egg production (EP) responses for a full production cycle. A total of 288 Bovan Single Comb White Leghorn laying hens were fed diets containing 0, 5, 10, 15, 20, or 25% DDGS from 24 to 46 wk (phase 1) and 47 to 76 wk (phase 2) of age. The diets were formulated to be isoca...

Riboflavin and niacin concentrations of bison cuts.

We analyzed the riboflavin and niacin contents of individual cuts from clod (triceps brachii), ribeye (longissimus thoracis), top round (semimembranosus), and top sirloin (gluteus medius) from 24 fed bison bulls. The bulls came from producers in the United States and Canada and had consumed concentrate diets plus hay free choice for at least 100 d. The mean riboflavin and niacin concentrations ...

Supplemental wheat bran and microbial phytase could replace inorganic phosphorus in laying hen diets

An experiment was conducted to determine effects of wheat bran (WB) phytase on production performance and nutrient utilization in laying hens. Three hundred and seventy-five Lohmann hens at 32 weeks of age were randomly allotted to treatments of fifteen hens per pen with five pens per treatment. Five experimental diets were formulated. Diet one (control) contained 0.19% inorganic phosphate (Pi)...

The effect of using different levels of shrimp meal in laying hen diets.

The shrimp industry in Central America has grown significantly. Much waste is generated by this industry because of the high percentage of shrimp heads, exoskeletons, and soluble components lost during processing. The objective of this study was to measure the effect of substituting different levels of shrimp meal (SM) for soybean meal (SBM) in layer diets. A control corn-soybean layer diet and...
