Cage Growing

Chicks started in cages should be placed in the upper levels (decks),

where the air is warmer and the light brighter. Intermingle seemingly

weak and strong chicks (from different transport boxes) to allow the

stronger chicks to train the weaker chicks to nd water and feed. Thestarter feed should be placed inside the cage on the cage paper after

the chicks have had a chance to drink. Continue feeding on the paper

for the rst 7 to 10 days after arrival. The chicks can be distributed

among all cage levels at around 14 days of age when the space has

become too restricted in the upper levels.

Place paper on the cage oor during the brooding period. This will allow

supplemental feeding on the cage paper to quickly get chicks eating.

Place feed on the cage paper in front of the permanent feeder to train

chicks to move towards the feeders. Remove the paper by 14 days

of age to avoid build up of feces that could lead to infectious bursal

disease or coccidia infections.

Waterlines should be ushed prior to arrival of the chicks. Drinking

water temperature should be 25 to 30C (77 to 86F) for the rst week.

Adjusting water system pressure in nipple drinkers to create a hanging

drop will help chicks nd water. Cup drinkers should be manually lled

during the rst 3 days to train chicks to drink.

Floor Growing

It is essential to grow the birds on the oor when they will be housed

in oor systems for the laying period. Ensure that the feed and water

systems in the growing and laying facilities are compatible. Ideally, the

growing house should have elevated bird walkways with feed and water

stations. Flocks housed in all-slat houses during lay should also be

grown on slat or wire oors.

Chicks started on the oor should be transferred from the transportboxes to the litter under the water lines or near drinkers to encourage

drinking. To make it easier for the chicks to drink, use supplemental

drinkers in addition to the automatic drinkers. The supplemental

drinkers should be used for the rst 10 to 14 days and can also be

used for administering the rst vaccination if given in the water. When

used, gradually move supplemental feeders and drinkers towards the

permanent feeders and drinkers in the room to train the chicks to nd

the permanent feeders and waterers.

Birds should be grown in housing that allows adjustment to the lighting

program and the light intensity. The lighting programs are usually

similar to those used for birds in cage production, but light intensity may

be different. It is important to provide oor-grown birds with enough

light intensity to allow them to navigate their environment. A light

intensity of 20 to 30 lux (2 to 3 foot-candles) should be used during the

rst week of age, dropping down to 15 lux (1.5 foot-candles) by week

4 and remaining at the level until week 15 of age. At week 15 of age,

gradually increase the light intensity, reaching 20 to 30 lux (2 to 3 foot-

candles) by the time the pullets are transferred to the layer house. Birds

moving into open-sided housing should have higher light intensities of

30 to 40 lux (3 to 4 foot-candles) at the time of housing.

Hy-Line W-98 Growing Recommendations

Ambient Temperature and Relative Humidity

Observing the chicks will tell you whether or not the temperature is

correct. If they are too cool, they will huddle near the heat source. Ifthey are too warm, they will spread out away from the heat source. If

there are drafts, they will huddle in groups to get away from the spot

where the cool air enters the heated area. Comfortable chicks will

spread out uniformly, without huddling, throughout the brooding area.

Look for signs of overheating (panting and drowsiness) or chilling

(huddling and loud chirping) and make appropriate adjustments. Heat

control is more critical in cage brooding because the chicks cannot

move to nd their comfort zone.

Birds are very sensitive to extremes of relative humidity. A relative

humidity below 30% will cause increased agitation of the chicks and

may cause aggressive behavior. Conversely, excessive moisture

may cause wet litter conditions, associated with high ammoniaconcentrations, poor air quality, enteric diseases, and respiratory

problems. Ideally, the relative humidity should be between 40 and 60%.

Humidity control becomes increasingly important when warm-room

brooding in cold climates. To increase the relative humidity, water

can be sprayed on the walk ways or oors. Humidity will normally be

lowered to 30 to 40% by the end of the growing period.

Lighting Programs

Egg production is very closely related to the changes in day length.

Body weight gain in grow, egg numbers, egg size, livability, and total

protability can be favorably inuenced by a proper lighting program.

When open-type houses are used, which allow natural daylight to affect

the ock, the lighting program must be planned in conjunction with

changes in the natural day length. Because no two places have the

same sunrise-sunset times year-round, custom lighting programs for

any location worldwide are available.

The customizable lighting program is available in multiple languages

and will create a downloadable spreadsheet with sunrise and sunset

times for any location in the World and the lighting program for your

ock. Visit www.hyline.com to access the customizable lighting

program.

Water Consumption for Pullets and Layers

Drinking Water

Water is the most important nutrient and good-quality water must be

available to the birds at all times. Only in special cases (e.g., prior to

vaccine delivery through the drinking water), should drinking water berestricted, and then only for a short time and under careful monitoring.

Monitoring drinking-water intake

Water and feed consumption are directly relatedwhen birds drink

less water, they consume less feed, and production quickly declines

accordingly. As a general rule, healthy adult birds will consume twice

as much water as feed, although the ratio increases during periods of

warm weather. Installation and use of water meters in each house or

barn are recommended to monitor the ocks water intake on a daily

basis. Such daily water-intake records can be used as an early warning

of problems in the ock.

Water consumed per 100 birds per day

Chicks should consume 0.83 liters (0.22 gallons)

per 100 birds on day one of age.

Hy-Line W-98 Non-Fast Molting Recommendations

Non-Fast Molting

Many producers are using programs to induce molting which do not

involve fasting of the birds because of welfare concerns. The Hy-Line

laying hens will perform very well after a rest, particularly in the latter

weeks of the molt cycle with excellent shell quality and persistency. Theoptimum age for molting depends on the current ocks performance,

local egg markets, and scheduling of the next pullet ock, but is usually

around 65 to 75 weeks of age.

Induced molting can extend the productive life of a ock by improving

rate of lay, shell quality, and albumen height. However, these levels

will be somewhat lower than the best pre-molt values. Egg size will

essentially remain unaffected and will continue to increase after egg

production resumes.

A ock can be induced to cease laying by a variety of methods. A

welfare-oriented non-fast molting method has been developed that

results in post-molt performance equivalent to that of fasting methods.

Free access to water at all times during the non-fast molt is essential.

It is important to know the sodium (Na) content of the drinking water.

High sodium levels (i.e., 100 ppm or higher) can adversely affect this

type of molt program.

The best post-molt egg production is achieved after a completecessation of egg production that lasts for at least 2 weeks and a

concomitant loss of body weight to the 18-week target weight (although,

in the case of heavy birds, it is not recommended that the body weight

loss exceed 24 to 25% of the pre-molt body weight. After the initial body

weight loss, the body weight can be held steady by a combination of

adjusting the number of feedings per day and/or a shift to a higher-

energy (laying-hen-type) diet.

Because of the importance of the body weight loss during molt, it is

recommeded to closely monitor the body weight of the ock during the

molt process. Body weights should be collected twice per week from

the same cages every time. The cages should be selected from bottom,

middle, and top tiers; all rows; and from the front, middle, and end of

the house.

The following table outlines the recommendations for the non-fast molting program recommended by Hy-Line. Note that there are many different

successful methods to molt laying hens.

The higher house temperatures will help reduce feed

intake and, in turn, facilitate a reduction in body weight

to the 18-week target weight (note that white laying

hens should not lose more than 24-25% of their pre-

molt body weight and brown laying hens should not

lose more than 21-22% of the pre-molt body weight).

1 Include a probiotic or a complex-carbohydrate product (e.g., mannan-oligo-saccharide; MOS) at 0.5 kg per metric ton (1 lb per 2000 lb) finished diet through all

stages of the molt program.2 Feed intake depends on house temperature. Lower temperatures (colder) may require more feed.3 Depends on air quality in house. The suggested house temperatures may not be achievable in cold weather.4 Set lights at 8 hours or natural day length in open-sided houses. Normally, it is not necessary to change the light intensity.5 The molt diet is high in fiber (low in energy) and contains no added sodium (Na) (i.e., no added NaCl or NaHCO

3).

6 Light-stimulate the birds to bring the birds into production by increasing the light hours to the number of hours they were given before the molt (e.g., 15 or 16

hours). This increase can be performed over 1 week (i.e., from 8 hours to 16 hours in a single day) or over 2 weeks (i.e., from 8 to 12 hours and then from 12 to16 hours). Monitor and control feed intake for the first few days after light stimulation to avoid fat birds as they are getting back into lay (which would significantly

increase egg weight in the second cycle).7According to the post-molt nutrition recommendations for the individual Hy-Line variety.

Hy-Line W-98 Post-Molt Nutritional Recommendations

1The recommended energy range is based on the energy values shown in the Hy-Line Online Management Guide. Differences in the metabolizable energy value

assigned to feed ingredients of the same name can differ substantially; in some cases, the recommended dietary energy content may have to be adjustedaccordingly (see Hy-Line Online Management Guide for additional information).

2Total amino acids are only appropriate with a corn and soybean meal diet; please formulate the diet on digestible amino acid basis if a substantial amount of other

protein-supplying ingredients are used.3The added calcium carbonate (limestone) should be in particle sizes of less than 2 mm.4The sodium content in the Molt diet should not exceed 0.035%.
