Phytogenic products proven

 

Phytogenic products such as Biostrong® 510 and Biostrong® Forte have proven to be effective in broiler production, with the following benefits:

• Enhances nutrient digestibility and retention[1,2,3]

• Facilitates nutrient utilization and optimizes feed conversion ratio (FCR) by at least 2%[1,4]

• Aids in at least 1% body weight (BW) gain through nutrient utilization[1,4]

• Significantly reduces ammonia emissions[5]

• Supports intestinal health and improves bone strength[6]

Biostrong® Forte combines the benefits of Biostrong® 510 with the synergistic effects of esterified short and medium chain fatty acids for an optimal microbial environment in the gastrointestinal tract. In addition, Biostrong® Forte:

• Enhances foot pad quality[7]

• Aids in vitality[1,2,3]

 

Clostridium perfringens Challenge Trial is Broiler Chickens

 

Delacon sponsored two identical trials at Southern Poultry Research (2015)[7] to compare the efficacy of the Biostrong® Forte and Biostrong® 510 phytogenic feed additive program to the antimicrobial growth promoter Virginiamycin.


This project utilized 3,200 Cobb X Cobb male broilers in a randomized block design:
• NC (negative control): non-medicated feed
• PC (positive control): 20g/ton Virginiamycin
• T1 (Treatment 1) Biostrong® Forte at 1.5 lb/ton for Day 0-21; Biostrong® 510 at 0.3 lb/ton for Day 21-49
• T2 (Treatment 2) Biostrong® Forte at 1.5 lb/ton for Day 0-28; Biostrong® 510 at 0.3 lb/ton for Day 28-49


A standard corn/soy based commercial diet was used as the basis for each treatment. Starter, grower and finisher diets were fed until day 21, 35, and 49 respectively. All birds received a Coccivac® B vaccination on day 0 and were challenged with C. perfringens (108 CFU/bird) on days 19, 20, and 21.

The optimal feeding duration and dosage rate of Biostrong Forte was analyzed

 
Determination of Optimal Dosage Level of Biostrong Forte

The program for optimal Feed Conversion Ratio with Biostrong® Forte in combination with Biostrong® 510 is 28 days at a dosage of 1.5 lb/ton (P ≤ 0.1).

Day 21 Feed Conversion Ratio and Body Weights.

Figure 3. Day 21 Feed Conversion Ratio and Body Weights.

FCR and BW of the positive control and both treatments are shown to be significantly improved over that of the negative control.

Day 28 Feed Conversion Ratio and Body Weights.

Figure 4. Day 28 Feed Conversion Ratio and Body Weights.

FCR is improved for the positive control and both treatment groups while no statistical differences in BW were documented.

Day 49 Feed Conversion Ratio and Body Weights.

Figure 5. Day 49 Feed Conversion Ratio and Body Weights.

The FCR at day 49 indicates the positive control was significantly improved over both treatments 1 and 2, which showed no statistical differences. The BW at day 49 exhibited no significant differences between the positive control and treatments 1 or 2.
