The Cobb500 for Asia-Pacific

The Cobb500 for APAC

For your business to thrive, you need genetic excellence that delivers the best economic results. With our genetic lineage, drive for innovation and precision selective breeding, we have enhanced the performance of the Cobb500 for APAC. This broiler breeder is designed to help you confidently navigate modern poultry production and achieve your business goals.

A highly active bird with improved genetics delivering more chicks per hen.

Sexually matures early
Low mortality rates rearing though production
Comes into lay rapidly after photostimulation
Persists in egg production

A new tool to help you optimize flock nutrition

As always, the Cobb500 for APAC supplement provides standard nutrient and feed intake guidelines based on formulations for each feed phase (Starter through Breeder). Cobb nutritionists have also developed a Recommended IntakeTable (RIT). The new RIT offers precise weekly targets for energy, protein, and lysine, based on reformulating diets each week. The standard nutrient intake guide is optimized to meet birds’ needs over each entire phase using consistent feed types, while the RIT gives nutritionists added detail to refine formulations when adjustments to Cobb recommendations are necessary.

To maximize genetic potential, change the way you feed and manage Cobb birds.

Nutrition

The Cobb nutrient recommendations are based on mash feed. If crumble or pellet feed is provided, decrease energy recommendations 20 to 40 kcal/kg.

Rearing

Provide Chick Starter feed up to 5 weeks of age for good skeletal structure and well-developed feathers.
Ensure consistent weight gain through rearing. Do not allow weight gain to plateau.
100% of the hens should have pelvic fat before photo-stimulation (22 weeks).

Feeding into Lay

• Expect the first egg 8 to 12 days after photo stimulation. Climb to peak egg production is rapid which requires large increases in feed allocation. Don’t hesitate to allocate necessary feed increases.

• Make sure that hens are consuming higher calcium Breeder 1 (B1) by 1% egg production. Initiating B1 shortly before the first egg will not cause issues, but delaying B1 could cause mortality and thin eggshells.

Peak Production

Peak production will occur between 28 and 29 weeks.
Good uniform flocks will respond well to fast feed increases to peak. Adjust the feed amounts proactively and reach peak feed at the range of 55 to 60 HD% with 475-485 kcal/bird/day. Consult your Cobb Technical team if the flock has poor uniformity to help design a feeding program to peak.
Feed peak feed longer and carefully reduce feed post-peak to prevent a drop in egg production. Focus on daily body weight gains, daily egg weights, and feed clean up time to determine feed amounts.

Post Peak

Ensure steady body weight gain from 40 to 50 weeks of age for good laying persistency. Slowly and cautiously reduce weekly feed amounts.
Increase calories and calcium while reducing protein and phosphorous by switching to Breeder 2 at 40 weeks.
