Introduction

The Rowan Ranger®, an Aviagen® specialty product for the slower-growing broiler market, has recently been launched into Europe. The Rowan Ranger is the fi rst commercially available product from the Rowan Range®; a range of speciality colored birds developed to meet the needs of selected markets, including the slower-growing, free-range, and organic markets.

The Rowan Ranger is a slower-growing colored broiler which offers excellent performance, superb meat yield and increased customer fl exibility in their product choice. As a slower-growing product there are some key management differences between the Rowan Ranger and the standard Aviagen product range and the purpose of this document is to provide information on how to appropriately manage the Rowan Ranger. The advice covers parent stock, hatchery and broiler management and is based on a combination of data from trials and the expertise and practical knowledge of the Aviagen representatives. This document includes Performance Objectives for parent stock and broilers and Nutrition Specifi cations and should be used in conjunction with, and as a supplement to, the local Parent Stock and Broiler Handbooks supplied by Aviagen.

Parent Stock Management

The main market for the Rowan Ranger is, for now, Europe, where local economic drivers (relatively high stocking densities, high labor and land costs) favor parent stock management which achieves 5% egg production at 23 weeks of age. The information within this document therefore focuses on management strategies which are appropriate for early maturing fl ocks.

For all other general aspects of Rowan Ranger parent stock management the local Parent Stock Handbook should be referred to.

Rearing 0 to 20 weeksManagement of the Rowan Ranger in rear should be similar to that for the standard Aviagen products (for example in Europe the Ross® 308).

Brooding Management

As for all Aviagen products it is important to get the Rowan Ranger off to a good start through the use of good brooding management practices. The brooding set up must provide easy access to feed, water, heat and light (Figure 1).

Figure 1. Good brooding set up showing adequate access to feed, water and light and where the temperature is correct. Chicks are evenly spread throughout the entire brooding pen, eating, drinking and vocalizing contentedly. There is no evidence of panting or huddling.

Achieving the correct environmental temperature is key to getting the birds off to a good start and recommended environmental conditions (Figure 2) must be achieved 24 hours prior to chick placement. Rowan Ranger parent stock are slightly smaller chicks than Ross 308 and may require brooding temperatures 1-2°C higher than those recommended. Equally, inadequate fl oor temperatures at placement may result in the birds becoming easily chilled. Bird behavior should determine whether or not environmental conditions are correct.

Other key management points during brooding include;

• Always monitor actual chick behavior to determine if house temperatures are correct (see Figure 1). If bird behavior indicates that temperatures are too hot (chicks spread out, panting and no vocalization) or cold (chicks huddling around brooder, distress-calling) then appropriate adjustments must be made. A brooding pen used for the fi rst 3-7 days of life will help to keep chicks near the heat source, feed and water.

• Fresh litter, free from dust, should be spread to a depth of 8-10 cm. Where fl oor temperatures are adequate (28-30°C), if fl oor feeding is practiced and litter disposal is a problem then litter depth can be reduced to 1.5–2.5 cm. This will help reduce problems of feed being lost in the litter which can be an issue with these birds as they need to be fed nearly ad libitum for a number of weeks in order to achieve required growth rates

• Monitor crop fi ll regularly during the fi rst 48 hours after placement. The crop should be full, soft and rounded in chicks that have found food and water (Figure 3). If the crop is full, but the original texture of the crumb is still apparent, the bird has not yet consumed enough water. Guidelines for target crop fi ll in the fi rst 48 hours are given in Table 2.

Other key management points during brooding include;

Water ManagementBirds must have an easy and plentiful access to fresh, clean water from placement. Supplementary drinkers should be used during the fi rst 3 days after placement to encourage water intake (see Figure 1). During the fi rst 24 hours walking through the fl ock when checking crop fi ll and replenishing the feed on the paper will create activity in the fl ock, stimulating the chicks to feed and drink. This is particularly important where transport times have been longer.

Feed ManagementFeed management for the Rowan Ranger is the same as that for other standard Aviagen products. The key points are:

• A sieved crumble or mini-pellets should initially be provided in feeder trays (1 for every 80-100 birds) and on paper spread across at least 90% of the brooding area.

• Make feed available in mechanical feeding systems from day one and do not remove paper from the brooding area until the birds have learned to feed from the mechanical feeders.

• Where track feeding or pans are used birds should be gradually introduced to the automated system from 8 days of age onwards. Full transfer to the automated feeding system should occur over a 2-3 day period during which time the amount of feed in the automated system should be gradually increased. During the transitional period to the automated system manual feeding should continue.

• Where spin feeders (fl oor feeding) are used, population size per spinner should be no more than 1000-1500 birds, depending on the pen shape/spinner type. Pellets should be of good physical quality, and a pellet with 2.5mm diameter and 3-4mm length should be used.

• The transition to fl oor feeding must be well managed. A typical well managed transition from hand feeding to spin feeding and from crumble to pellet feeding is given in Table 3.

• With fl oor feeding it is also important to pay particular attention to feed clean-up time. Birds should clear up all feed; no feed should be left in litter. Any feed left in the litter may be found by the fl ock later on leading to problems with body weight control. Check for feed in litter regularly. If feed is found in the litter feed levels may need to be amended depending on body weight.

• Monitor feed depth, distribution time and clean-up time routinely at several points around the house and adjust feeder height regularly with bird age and growth.

• If track feeders are used all feed should be distributed to each population within 3 minutes. If feed distribution is a problem, distribution time can be reduced by placing a supplementary feed hopper halfway around the feeder loop.

• Pan feeders provide good feed distribution if managed properly. Pan feeders must be checked regularly to ensure that all pans are receiving feed and that the lines remain charged.

Body-weight Profi lesThe Rowan male and Ranger female body-weight profi le recommendations are given below (Figures 4 and 5 and Appendix 1 at the end of the document). The Ranger female comes into production quickly, and management practices in both rear and lay must account for this. The body-weight profi les given in Figures 4 and 5 below will allow birds to achieve 5% at 23 weeks of age, but be aware the Ranger female may actually achieve 5% even earlier than this. Management for the Ranger female must be proactive and responsive if drops in production are to be avoided. Birds must be fed to achieve recommended body weights to ensure they achieve correct maturity at POL. Weekly weight gain of 20% or more between 17 and 22 weeks should be avoided as this will result in birds coming into lay early leading to a high number of small eggs.Grading is a key management strategy for the Ranger female. Because the Ranger female comes in to lay quickly a higher fl ock uniformity is necessary to ensure that early performance is optimizied and persistency of production maintained.

Management for the Ranger female must be proactive and responsive if drops in production are to be avoided. The body-weight profi le for the Rowan male is lighter than the standard Aviagen male from 4 weeks of age. The Ranger female is a dwarf female and the body weight profi le of the Rowan male must account for this.

Lighting ProgramsThe Ranger female is early maturing by nature; it is also much more responsive to light stimulation than other standard Aviagen products. It is recommended that light stimulation should occur around 147 days or 21 weeks (Table 4). However, the actual age at which photo stimulation occurs will depend on the average fl ock body weight and fl ock uniformity. If the fl ock is under weight (~100g) or uneven (CV% > 10) at time of light stimulation, then the fi rst light increase should be delayed by a week.

Because the Ranger female is so responsive to light and comes into lay so quickly it is especially important that birds are maintained at the recommended body weights for age. The Ranger female must not be allowed to get over weight between 17 and 22 weeks of age as this might stimulate onset of sexual maturity even in the absence of light stimulation (this is particularly important when birds are reared in open-sided houses). If birds are overweight at this time light stimulation should be delayed by one week.

† Average intensity within a house or pen measured at bird-head height. Light intensity should be measured in at least 9 or 10 places and include the corners, under lamps and between lamps. Ideally, the standard error should not exceed 10% of the mean.

‡ The day length may be increased abruptly in a single increment from 8 to 13 hours without adversely affecting total egg production provided the body weights are on target and the fl ock is uniform (CV ≤ 10%). An abrupt increase in day length induces a higher peak rate of lay, though with slightly poorer persistency, to that expected for a programme involving a series of increments. However, total egg production for the two types of lighting programmes will be similar.

As with all standard Aviagen products, birds in closed houses should be reared on short days of 8 hours from 10 days of age. If birds are reared in open-sided houses then they should be allowed to experience whatever the natural day length is.

Peak day length for the Rowan Ranger in lay should not exceed 13 hours of light per day. In case of excessive fl oor eggs it might be helpful to increase day length by 1 hour to 14 hours. Further increases in day length will advance the onset of adult photorefractoriness and result in inferior rates of lay at the end of the laying cycle. In open-sided houses day length will vary according to placement date and natural day length patterns. If the longest natural day length in lay is expected to exceed 13/14 hours, the combination of natural and artifi cial light should be increased to equal the expected longest natural day length. It is important that birds do not experience a reduction in day length during lay.

Lighting ProgrammesThe Ranger female is early maturing by nature; it is also much more responsive to light stimulation than other standard Aviagen products and comes into lay quickly. It is recommended that light stimulation should occur around 146 days or 21 weeks (Table 4). However, the actual age at which photo stimulation occurs will depend on the average fl ock body weight and fl ock uniformity. If the fl ock is under weight (~100g) or uneven (CV% > 10) at time of light stimulation, then the fi rst light increase should be delayed by a week.

Because the Ranger female is so responsive to light and comes into lay so quickly it is especially important that birds are maintained at the recommended body weights for age. The Ranger female must not be allowed to get over weight between 15 and 22 weeks of age as this might stimulate onset of sexual maturity even in the absence of light stimulation. This is particularly important when birds are reared in open-sided houses.

Laying Period (21 weeks to depletion)

Managing Stock TransferTransfer of stock to the laying facilities must be managed with appropriate care. Extra feed (approximately 50% more) should be given on the day before and the day of transfer. Feeding space must not be reduced and lighting programs and biosecurity should be synchronized between rearing and laying houses.

An assessment of crop fi ll on the day of transfer, 30 minutes after the fi rst feed and then again 24 hours later will provide an indication of whether or not birds have found feed and water after transfer (Figure 6). If crop fi ll is found to be inadequate (ideally all birds should have a full crop) the reason for this needs to be established (e.g. inadequate feeder space, feed distribution or availability of feed) and corrected as soon as possible. Continue to check crop fi ll an hour after feeding for the fi rst 3 days after transfer, to make sure all the birds are fi nding the feed and water.

Figure 6. Photo of crop fi ll after transfer.

Water should be freely available to the birds as soon as they arrive at the laying facilities. Running track or pan feeders in the dark (i.e. turn the lights off to fi ll them for the fi rst time) will aid with feed distribution.

Moving birds to the laying house should be scheduled so that all the birds have time to fi nd both feed and water in their new housing before the lights are turned off at night.

Several days after transfer it is advisable to start running the egg collection belt so the birds become accustomed to the noise and movement of the belts. This will encourage nest use when laying begins, reducing the incidence of fl oor eggs.

Feeding Into ProductionMonitoring body weight and providing appropriate feed increases into production is important with the Ranger female and the procedure for determining the pattern of feed increase from 5% production to peak is the same as that for the standard Aviagen products.

The difference in feed quantity allocated prior to fi rst egg and the target feed level given at peak (see the Rowan Ranger Performance Objectives at the end of the document for more details) allows a feed allocation schedule to be established. An example feeding program to peak for the Ranger female is given in Table 5. Up to 5% production birds should be fed according to body weight.

Actual feed amounts up to and at peak should be adjusted for each individual fl ock depending primarily on body weight, daily egg production, daily egg weight and uniformity. The following should also be taken into account;

• Feed clean up time• Energy density of the feed• Egg weight and change in egg weight• Environmental temperature

Responsive management of birds coming into production requires frequent observation and measurement (ideally daily) of the production parameters given above and this is particularly important for the Ranger female which comes into production rapidly. The feed increases given must be adjusted appropriately to support production and feed increases beyond recommended peak feed amounts may be required in high producing fl ocks. Small but frequent feed increases to the peak feed amount should be given to ensure that desired body-weight gains are achieved.

Feed Reduction After Peak Feed reduction after peak is the area of management that will have the biggest impact on persistency of lay and hatch and needs to be handled with care.

Timing and amount of feed reduction will depend on the following observations:

• Body weight and body-weight change from the start of production.• Daily egg production and the hen day production trend.• Changes in feed clean-up time.• Daily egg weight and egg-weight trend.• Egg mass trend.• Health status of the fl ock and feathering condition.• Ambient environmental temperature.• Feed composition i.e. feed texture, including energy and protein levels.• Quantity of feed (i.e. energy and protein intake) at peak.• Flock history (i.e. rearing and pre-peak performance).

Feed levels after peak should be gradually reduced to achieve 138g at depletion but the actual program of feed reduction should be carried out in response to observations and measurements of bird condition and egg production in the fi rst instance.

To enable the farm manager to monitor and establish an appropriate feed reduction program, it is important that the following characteristics are measured, recorded and graphed onto a chart:

• Daily (or weekly) body weight and body-weight change relative to the target.• Daily egg weight and egg-weight trend relative to the target.• Daily changes in feed clean-up time.

Feed allowances after peak should be adjusted to compensate for any unexpected changes in the above characteristics.

When considering feed levels after peak, seasonal temperature variations must be taken into account. A fl ock peaking in winter will fi nish production in the late spring or summer. At peak, they will have needed more feed to support the demands of egg production in cooler temperatures, but as the fl ock ages environmental temperature will increase and so birds can tolerate a more severe feed withdrawal program. A summer peaking fl ock, peaks in warmer weather and depletes in colder weather, so a less severe feed withdrawal program is required in this situation.

Separate Sex FeedingThe Rowan male is smaller than the standard Ross male. For this reason the vertical height of the female feeder feeding grills should be reduced to a maximum of 55 cm.

Male Management Male management practices for the Rowan male are similar to those for the standard Aviagen male. Good male management is as important for the productivity of the Rowan male as it is for the standard Aviagen males. The key difference for the Rowan male is the body-weight profi le details of which are given in Figure 4 and at the end of the document (Appendix 1).

Nutrition

The Ranger female and the Rowan male do not receive any welfare treatments (beak treatment or de-clawing) and therefore good feather cover should be encouraged. The parent stock feed recommendations take account of this. To support feathering dig Meth, dig Meth + Cyst could be increased by 5-10% in the Grower diet.

Broilers

The Rowan Ranger broiler is a speciality product for the slower-growing bird market; it has a maximum growth rate of 45g per day to 56 days of age. The Rowan Ranger broiler does not need specialized management and should be managed with the same care and detail to attention as standard Aviagen broiler products. However, Rowan Ranger broiler chicks might be slightly smaller as egg size of the Ranger female is lower than that of the standard Aviagen products. Early environmental temperatures might have to be adjusted to account for this (temperatures may need to be increased by approximately 1°C depending on chick size).

Feed specifi cations for the Rowan Ranger broiler are given at the end of this document (Appendix 4).

Conclusions

The popularity of the Rowan Ranger is likely to increase due to its slower growth rate and its recognition as a slower-growing product by several accreditation schemes (the Beter Leven in the Netherlands and Freedom Foods in the UK). Management of the broiler is the same as that for the standard Aviagen products however there are some key management differences between the Rowan Ranger parent stock and the standard Aviagen parent stock products. Understanding these differences and modifying management appropriately to account for them will ensure that the performance of the Rowan Ranger parent stock is optimized.

The key points to consider when managing Rowan Ranger parent stock are:

• The Ranger female should be reared to recommended body-weight profi les adhering to recommended nutrition specifi cations.

• Feeding into production: Ranger females come into lay quickly. It is important that increases in feed take account of this. Rowan males should be managed with care and attention. Accurate and regular monitoring of body weight and condition is the key to maintaining good fertility.

• Keep to recommended stocking densities and, in lay, ensure that suffi cient nest and feeding space is provided.

Table 4. Processing performance.

The following tables indicate how yields of the major portions change with increasing live weight in each sex. Two types of processing are described: eviscerated yield is broken down into breast meat, thigh and drumstick to represent a portioning operation and into breast meat and leg meat to represent a deboning operation.

Defi nition of Processing Terms:Eviscerated %: eviscerated carcass (without neck, abdominal fat and internal organs) as a percentage of live weight.Breast %: breast meat (without skin and bone) as a percentage of live weight.Thigh/Drumstick %: whole thigh/drumstick (with skin and bone) as a percentage of live weight.Leg Meat %: sum of deboned thigh (without skin) and deboned drumstick (without skin) as a percentage of live weight.

NOTEThese fi gures represent dry yield. They do not include any moisture retained during chilling or processing. Carcass component yields will vary among processing plants depending on, for example, type of equipment used and the exact portion(s) being produced.

Achieved Crude Protein2 is not a “dietary crude protein minimum constraint”. The formulation priority is to meet all the recommended minimum essential amino acid levels. These achieved crude protein levels are not requirements per se, but instead are levels which will likely occur when formulating to the specifi ed essential amino acid minimums while using commercially available synthetic amino acids. The achieved crude protein levels actually observed will vary depending on the feed ingredients being utilized and their associated nutritional composition.

NOTES These feed specifi cations should be used as a guide. They require adjustment for local conditions and markets. A withdrawal feed should be fed to meet local legislation requirements for drug withdrawal times. This can be formulated to the same standards as the fi nal feed listed above.
