Recreation and Finishing of Swine: Strategies for Weight Gain and Cost Reduction for Slaughter

A rebreeding and finishing of pigs — from weaning to 25 kg until slaughter at 100 to 120 kg — are the phases where the feed cost represents 70 to 75% of the production cost. The pig farmer who masters feed conversion management in these phases holds the key to profitability — as each tenth of a point improvement in conversion represents R$ 5 to R$ 10 per pig slaughtered.

The modern pig grows from 25 to 120 kg in 90 to 110 days with a feed conversion ratio of 2.5 to 2.8 — performance that depends on genetics, environment, nutrition, and health. Finishing pigs in an integrated system has reduced risk but lower margin; the independent finisher has greater risk but can capture much higher margins when well managed.

When rebreeding and finishing are conducted with the correct diet, controlled environment, and preventive health measures, this segment can contribute significantly to job and income generation in Brazil.

Join our strategic actions for the implementation of the best solutions in the Brazilian agribusiness sector. Our activities, studies, and advanced research cover 20 chains and the 255 segments of the national agribusiness — from the grain chain to sustainable extraction, passing through horticulture, fruit growing, livestock, and much more.

The Innovation For Brazil to Produce More series was developed precisely to identify and implement the best solutions available in Brazil and around the world, across the 255 segments of the agribusiness sector — with accessible technical language, updated data, and focus on practical results for producers, suppliers, government officials, and marketers.

1.  Opportunities for Small Rural Producers

How to maximize average daily gain (ADG) and feed conversion in rebreeding and finishing

The ideal ADG (Average Daily Gain) in finishing is above 900g/day with conversion below 2.7 — a standard that requires quality feed, appropriate environment (temperature between 18 and 24°C), and absence of health challenges.

✔    Phase feeding: nursery, growth 1, growth 2, and finishing — each phase with specific nutrition

✔    Comfort temperature: 18 to 24°C — a pig outside of comfort spends energy for thermoregulation

✔    Correct density: 0.8 to 1.0m²/pig in finishing — overcrowding reduces ADG

✔    Control of Mycoplasma, Circovirus, and PRRS — main health challenges in finishing

✔    PRONAF and Pronamp for family pig finishing

The E-Book 01 — Strategic Manual for Small Rural Producers presents, in detail, the best solutions for the segment and the other 254 of Brazilian agribusiness — focusing on method, cost reduction, and progressive growth from Agro 1.0 to Agro 6.0.  Access now for BRL 99.00 →

2.  Opportunities for Micro and Small Local Suppliers

What equipment does the rebreeding and finishing phase require

Rebreeding and finishing require silos, automatic feeders, and ventilation systems to ensure maximum performance.

Solutions by area of engineering applied to the segment

Our activities, studies, and advanced research cover six major areas of engineering — and the chain requires solutions in all of them:

Electrical Engineering and Computing — automation of ventilation and nebulization for temperature control;

Electronic Engineering and IoT — temperature and NH₃ sensors; electronic feeders;

Control and Automation Engineering — phase automatic feeders; nipple drinkers;

Mechatronics and Robotics Engineering — feed silos; automatic distributors;

Renewable Energy Engineering — solar for ventilation and nebulization;

Data Science and Artificial Intelligence — feed conversion management; cost per kg produced.

✔    Automatic phase feeders for rebreeding and finishing

✔    Ventilation and nebulization system for temperature control

✔    Feed storage silos

✔    Weighing scales for monitoring ADG

✔    Consulting in phase pig nutrition

3.  Opportunities for Municipal Governments

How the municipality can support pig finishing and create a slaughter hub

The municipality that has technified pig finishing and a slaughterhouse with SIF retains the entire value chain — from feed to processed product — within its territory.

✔    Pig finishing program for integrated family producers

✔    Support for municipal pig abattoir with SIF

✔    Municipal IDM: average ADG of the local pig herd

✔    PNAE with locally slaughtered pig with inspection

✔    Waste management program and biodigesters

The E-Book 03 — Reference Guide for Municipal Governments presents a step-by-step process for secretaries and municipal managers to implement effective public policies for the 255 segments of agribusiness.  Access now for BRL 99.00 →

4.  Opportunities for Small Traders of Agricultural Products

How rebreeding and finishing create business for suppliers of nutrition and technology

The market for phase pig feed is the largest volume in pig farming — a pig consumes 200 to 250 kg of feed from weaning to slaughter, and the quality of the feed directly determines conversion and production cost.

For suppliers of finishing management technology, the market is growing with the increase of professionalization — real-time feed conversion control software has a proven ROI of 2 to 4 times the subscription cost.

Products with high commercial potential

The main products derived from this segment for local retail and foodservice:

Phase feed for rebreeding and finishing— the largest volume in pig farming;

Additives and growth promoters— high-value market per kg;

Automatic phase feeders— high ROI equipment;

Finishing management software— high return platform;

Finishing vaccines— permanent market;

Consulting in phase nutrition— high-value service.

Profiles of traders and their specific opportunities

✔    Feed factories: complete phased line for pig farming

✔    Additive suppliers: improving pig performance

✔    Feeder manufacturers: feeding automation

✔    Management software: real-time conversion control

✔    Veterinarians: health program for finishing

✔    Nutritionists: personalized phase diet

Growth strategies for local traders

The nutritionist who demonstrates the improvement of conversion by 0.1 point with their phase diet and calculates the impact in reais per pig slaughtered has the most powerful argument in the pig nutrition market. For a farm of 1,000 pigs/month, a 0.1 improvement in conversion is worth R$ 8,000 to R$ 10,000/month.

The PRONAF and Pronamp cover installations and feed. BNDES Rural finances silos and equipment.
