Practical Alternatives to In-Ovo Feeding for Early Chick Nutrition

Great question, Muhammad. While in-ovo feeding delivers nutrients before hatch, small and medium farms can still achieve early nutrient intake through simple, low-cost management adjustments that stimulate the chick’s digestive and immune development right after hatch.

<hr data-start=”565″ data-end=”568″>
1. Provide Immediate Access to Feed and Water
<ul data-start=”625″ data-end=”1028″>
No delay after placement: Every hour without feed or water increases early chick mortality and reduces lifetime weight gain.
Make sure feeders and drinkers are pre-filled before chicks arrive.
Feed on paper trays or chick paper across 60–70% of the brooding area for easy access.
Offer bright light (30–40 lux) for the first 24 hours to help chicks locate feed and water.

<hr data-start=”1030″ data-end=”1033″>
2. Use High-Quality, Nutrient-Dense Pre-Starter Feed
<ul data-start=”1097″ data-end=”1418″>

Choose a fine crumble or mini-pellet form for easy intake.
Include highly digestible protein (fish meal, soy protein concentrate) and readily available energy (oil/fat rather than excess starch).
Ensure adequate vitamins A, E, C, selenium, and probiotics to kick-start immunity and gut health.

<hr data-start=”1420″ data-end=”1423″>
3. Early Water Supplementation
<ul data-start=”1465″ data-end=”1683″>

Add glucose or dextrose (2–3%) in water for the first 24–48 hours — helps restore energy reserves depleted during hatch and transport.
Include electrolytes + vitamin C to prevent dehydration and stress.

<hr data-start=”1685″ data-end=”1688″>
4. Maintain Ideal Brooding Conditions
<ul data-start=”1737″ data-end=”1973″>

Temperature: 32–34 °C at chick level for the first 2–3 days, then gradually reduce.
Humidity: 60–70% to prevent dehydration.
Litter temperature should be warm and dry before placement — cold floors delay feeding.

<hr data-start=”1975″ data-end=”1978″>
5. Encourage Early Gut Development
<ul data-start=”2024″ data-end=”2262″>

Use prebiotics, probiotics, or acidifiers in early feed or water to seed a healthy gut microbiome.
Some producers use fermented feed or natural additives (like yeast derivatives or organic acids) for improved gut function.

<hr data-start=”2264″ data-end=”2267″>
6. Reduce Transport and Hatchery Delays
<ul data-start=”2318″ data-end=”2490″>

Coordinate logistics so that chicks reach the farm within 6–8 hours post-hatch.
Every extra hour of feed deprivation reduces 7-day growth and final body weight.Practical Alternatives to In-Ovo Feeding for Early Chick Nutrition

Heat Stress Management in Poultry

Excellent point, Samuel. Rising temperatures demand proactive measures to protect flock health and performance. Along with using anti-stress supplements (vitamins and electrolytes), farmers can combine nutritional, environmental, and management strategies for stronger resilience

<hr data-start=”598″ data-end=”601″>
1. Environmental Management
<ul data-start=”640″ data-end=”1071″>

Ventilation: Increase air exchange; add fans or exhaust systems to remove hot, humid air.

Cooling: Use foggers, misters, or evaporative pads during peak heat (but ensure good ventilation to avoid humidity buildup).

House Design: Insulate roofs, use reflective paint or shade nets, and orient houses east–west to reduce direct sunlight.

Reduce bird density during hot seasons to lower body heat load.

<hr data-start=”1073″ data-end=”1076″>
2. Water Management
<ul data-start=”1107″ data-end=”1348″>

Provide cool, clean water at all times — birds drink up to twice as much in hot weather.

Flush water lines during the day to prevent heating.

Add electrolytes + vitamin C to drinking water during peak heat stress periods.

<hr data-start=”1350″ data-end=”1353″>
3. Nutritional Adjustments
<ul data-start=”1391″ data-end=”1777″>

Feed during cooler hours (early morning or late evening).

Use high-quality, easily digestible feed ingredients — poor-quality protein increases body heat.

Supplement with vitamin E, C, selenium, betaine, and electrolytes to reduce oxidative stress.

Consider energy-dense diets with balanced amino acids to maintain intake when feed consumption drops.

<hr data-start=”1779″ data-end=”1782″>
4. Management Practices
<ul data-start=”1817″ data-end=”2130″>

Avoid catching, vaccination, or transport during the hottest hours.

Provide sufficient space per bird and clean litter to prevent suffocation or heat accumulation.

Observe for early signs of stress: open-mouth breathing, panting, wings spread, reduced feed intake, and increased water consumption.

<hr data-start=”2132″ data-end=”2135″>
5. Long-Term Prevention
<ul data-start=”2170″ data-end=”2307″>

Select heat-tolerant strains where possible.

Install temperature monitoring systems and maintain records for decision-making.Heat Stress Management in Poultry

. Vaccine Type

Live Fowl Pox vaccine (usually chick embryo–origin or tissue culture–origin virus).

Administered by wing-web stab method.

<hr data-start=”431″ data-end=”434″>
2. Recommended Schedule

Optional: If breeders are reared in endemic areas or under open housing where mosquito pressure is high, some programs add:

Pre-lay booster (around 18–20 weeks) or combined Fowl Pox + AE (Avian Encephalomyelitis) vaccination.

<hr data-start=”1143″ data-end=”1146″>
3. Important Management Points
<ul data-start=”1187″ data-end=”1680″>

Wing-web check: Always examine 50–100 birds 7–10 days post-vaccination for “takes” (small scab/swelling at the site). A good “take rate” = ≥95% of birds show a scab — confirming effective immunity.

Avoid stress (heat, feed changes, disease outbreaks) during vaccination.

Don’t vaccinate sick birds or during extreme temperature fluctuations.

Mosquito control: Vaccination complements, not replaces, vector management — as mosquitoes transmit fowl pox virus.. Vaccine Type

Live Fowl Pox vaccine (usually chick embryo–origin or tissue culture–origin virus).

Administered by wing-web stab method.

2. Recommended Schedule
Stage Age (in weeks) Vaccine Route Notes
Primary (1st) vaccination 8–10 weeks Fowl Pox (live) Wing-web stab Ensure birds are healthy and free from stress.
Booster (2nd) vaccination 16–18 weeks (before transfer to laying house) Fowl Pox (same type) Wing-web stab Confirms solid, long-term immunity during laying phase. Optional:
If breeders are reared in endemic areas or under open housing where mosquito pressure is high, some programs add:

Pre-lay booster (around 18–20 weeks) or combined Fowl Pox + AE (Avian Encephalomyelitis) vaccination.

S. Typhimurium can survive a long time in feed, litter, dust and slurry — persistence measured in months to years in multiple studies. PubMed+1

Environmental biofilms and dusty niches protect Salmonella from routine cleaning and reduce disinfectant efficacy. ScienceDirect+1

Environmental sampling methods (boot socks/boot swabs, drag swabs, dust and environmental swabs) reliably detect residual Salmonella and are recommended for non-invasive surveillance. PMC+1

Peracetic acid (PAA) and some PAA-based sanitizers show stronger activity against Salmonella and biofilms than some other chemistries; disinfectant choice and correct application matter.
