Feed Management and Body Weight Targets

H&N has always concentrated on maximizing the genetic potential for profitable egg production in the commercial cross without ignoring the importance of competitive parent performance. The management guide for parent stock is designed to help parent farms and hatcheries to achieve the best possible results applying management practices which have been successful in most situations.

Growing Period

Nutrient Requirements

Table 1: Recommended Nutrient Requirements for H&N Parent Stock (during the Growing Cycle)
The actual protein and energy levels used in the different diets will vary from area to area because of the ingredients available, the quality of the ingredients and the ambient temperature. The recommended protein, amino acid and energy levels for the rations fed at each age during the growing period are given in Table 1.
 

Vitamins & trace minerals

All rations need to be fortified with additional vitamins and trace minerals to assure that “H&N Layer Breeder“ parent stock will have good skeletal and muscle development and produce high quality hatching eggs. It is important that vitamins and minerals be added in approximately the levels shown in Table 2.
Vitamin C is synthesized by poultry normally. This vitamin is not considered as essential, but in some circumstances, like heat stress or hot climate it may be important/beneficial to add 100–200 mg/ kg complete feed during production period.

Body weights

Table 3: Nick Chick – Parent Stock Females* Body Weight Development with Standard Lighting Program
It is essential that the body weights of “H&N Layer Breeder” parent stock be checked weekly. Maintaining the proper body weight during the grow period will help “H&N Layer Breeder” parent stock perform to the maximum of their genetic potential. Proper body weights and feed consumption levels during the growing cycle appear in Table 3.

The exact amount of feed to give the growing flock each day will be influenced by the ambient temperature and feed quality.The uniformity during the entire growing cycle needs to be monitored very closely. At all times during the growing cycle, at least 85 % of the females should weigh within plus or minus 10 % of the average body weight. Uniformity may drop to levels below 80 % around the time when production reaches 50 % and then increase again.

Calcium

Beginning at approximately 45 weeks of age, it is beneficial to provide free choice oyster shell or coarse particle size limestone in hanging feeders. This allows the hens to adjust their own calcium intake, and at the same time does not force the cockerels to consume extra calcium. It also appears to be beneficial to hatchability to have at least 50 % of the calcium in the ration sourced from coarse particle size limestone or oyster shell.

Fortified Feeds

It is important to use a breeder vitamin pack which will meet the needs of the “H&N Layer Breeder” parent female. It is important that the vitamins and minerals be added in approximately the levels shown in Table 2 so the “H&N Layer Breeder” parent female will consume adequate amounts for the hatching eggs she produces.

Laying Cycle Feeding Program

Following tables show the suggested feeding program during the laying period. The “H&N Layer Breeder” parent stock rations are all formulated with a well balanced amino acid profile. This is beneficial in preventing performance problems, feather loss and nervousness, especially in high density breeder houses. Note that lower amino acid and phosphorus levels and higher calcium amounts are required as the birds age.

* Males and females have approximately the same feed consumption.
** Depends upon sexual maturity - 100 – 200 g higher for hens in production.
Variation is possible due to differences in feed composition and environments.
