Comparison of Growth in Nursery and Finisher Pigs: Impact of Lianfeng Probiotic Protein Supplementation

Bao'an Livestock Farm (Liujia and Mailiao Sites) Observation of growth performance in nursery and finisher pigs: Replacing 5% dehulled soybean meal with Lianfeng Probiotic Protein.

Bao'an Livestock Farm (Liujia Nursery Site): June 20 – July 19, 2021

	Weeks of Age	Avg. BW (kg)
Before Supplementation	12	28
After Supplementation	11	30

Analysis of Trial Results:

The analysis is based on the average values obtained from individual weighings.
The average body weight of nursery pigs improved from 28 kg at 12 weeks of age to nearly 30 kg at only 11 weeks of age.
Based on these results, it is confirmed that the use of Lianfeng Probiotic Protein is highly effective in enhancing the weight gain and growth rate of nursery pigs.

Bao'an Livestock Farm (Mailiao Finisher Facility): Supplementation commenced on June 20, 2021.

Date	Number of Heads Sold	Male-to-Female Ratio	Total Weight (kg)	Average Weight (kg)
June 23	100	48:52	11142	111.4
June 30	100	37:64	11267	112.6
July 12	100	69:31	11996	119.9
July 22	100	50:50	11901	119.0

Analysis of Trial Results:

Growth Performance: Following the addition of Lianfeng Probiotic Protein, based on the marketing dates, the average shipping weight increased from 111.4 kg to 119.9 kg in just 22 days. This represents an average increase of approximately 8 kg per head.
Projected Sales: Based on the current shipping intervals, the estimated monthly output is 300 heads.
Feed Cost Analysis: With an average daily feed intake of 2.5 kg per finisher pig, the monthly feed consumption is approximately 22.5 tons. At an additional cost of NT$750 per ton, the total monthly feed expense increases by: (22.5 tons x NT$750 = NT$16,875)
Estimated Revenue from Weight Gain: (Calculated from the third batch on wards): (300 heads x 8 kg = 2,400 kg)
Total Market Value of Weight Gain: (2,400 kg x NT$80 = NT$192,000)
Monthly Profit Increase for the Finisher Farm: NT$192,000 - NT$16,875 = NT$175,125
