Split Feeding for Laying Hens to Reduce Nutrient Waste
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional feeding methods for laying hens do not account for the varying protein and calcium needs throughout the day, leading to uneconomical nutrient intake and excessive environmental emissions.
Innovation Solution
A split-feeding method where hens receive a higher protein and lower calcium feed in the morning and a lower protein and higher calcium feed in the afternoon, tailored to their physiological needs, using specific nutrient compositions for each phase.

Engineering Contradiction Analysis
1Loss of substance
If traditional compound feed is supplied throughout the entire day with the same composition, then the feeding system is simple and economical in terms of feed preparation, but hens take in more protein than needed in the afternoon leading to nutrient waste and excessive environmental emissions
Solution Approach 1:
The daily feeding process is segmented into two distinct phases: morning feeding (6:00-12:00) with high protein feed (16-18% crude protein) and afternoon feeding (12:00-18:00) with low protein feed (12-14% crude protein). This segmentation allows precise matching of nutrient supply to the hen's physiological needs at different times of day, reducing protein waste while maintaining egg production efficiency.
Solution Approach 2:
The feeding system dynamically adjusts feed composition based on the time of day and the hen's changing physiological requirements. The protein content transitions from high in the morning to low in the afternoon, while calcium content transitions from low to high, creating a dynamic nutrient supply system that adapts to the hen's metabolic demands throughout the day.
2Object-generated harmful factors
If the same compound feed composition is used throughout the day, then the feeding management is simple, but undigested protein escapes rapidly through the short intestinal tract causing excessive harmful emissions
Solution Approach 1:
The feed is segmented into two distinct compositions based on time of day: morning feed with high protein (16-18% crude protein) and low calcium (1.0-1.5% calcium), and afternoon feed with low protein (12-14% crude protein) and high calcium (2.5-3.5% calcium). This segmentation ensures that protein is primarily supplied when the hen's intestinal tract is most efficient at absorption, reducing undigested protein escape and harmful emissions.
Solution Approach 2:
The nutritional parameters of the feed are changed based on the time of day: crude protein content varies from 16-18% in the morning to 12-14% in the afternoon, while calcium content varies from 1.0-1.5% in the morning to 2.5-3.5% in the afternoon. These parameter changes optimize nutrient absorption efficiency and reduce harmful emissions.
3Productivity
If high protein feed is supplied throughout the day to meet peak production needs, then egg production is maintained at high levels, but feeding costs increase and environmental impact worsens
Solution Approach 1:
The feeding regimen is segmented into high protein morning feed (16-18% crude protein) and low protein afternoon feed (12-14% crude protein), allowing the hen to receive adequate protein during the morning when it is most needed for egg production, while reducing protein supply in the afternoon when demand is lower, thus optimizing feeding costs.
Solution Approach 2:
The crude protein parameter is dynamically adjusted from 16-18% in the morning to 12-14% in the afternoon, matching the hen's physiological demand patterns. This parameter change maintains egg production efficiency while significantly reducing feeding costs and environmental impact compared to continuous high protein feeding.

AI summary
The present invention relates to a method for feeding laying hens, wherein the daily feed ration is given to the hens in two phases, during the morning and afternoon feeding, wherein the morning feed ration has a higher protein content and a lower calcium content than the afternoon feed ration. For feed of 1 kg with a moisture content of 12%, the morning feed ration is prepared according to the following content values: 13-15% crude protein; 1.5-2% calcium; 0.2-0.75% phosphorus and 10-11.3 MJ metabolizable energy. The afternoon feed ration is prepared according to the following content values: 12-13.5% crude protein; 4-5.5% calcium; 0.1-0.8% phosphorus; and 9.8-10.2 MJ of metabolizable energy. The invention further relates to a morning and afternoon compound feed applicable in such a split-feeding method.
