Inorganic Sulfate and Fish Solubles in Commercial Laying Hen Diets

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...

Use of Distillers Dried Grains Plus Solubles in Laying Hen Diets

A major emphasis on ethanol production in the US has led to the construction of new ethanol plants and an increased production of distillers dried grains plus solubles (DDGS). In the past DDGS came largely from the beverage industry and consisted of several grains used during fermentation. Recently, a majority of the DDGS produced is from corn fermentation for ethanol production. Little researc...

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)...

Laying Hen Heat and Moisture Production under Commercial

Astudy was carried out with the objective of establishing heat and moisture loads in three commercial egg laying units in Alberta under winter conditions. The units studied were typical of triple-deck, deep-pit, and shallow-gutter, caged systems. Each unit was monitored for six 24-h periods over 4 mo. Adata acquisition system was used tocollect the data necessary to carry outa complete heat and...
