BIOFEED RASANIMAL NUTRITIONDairy field-study dossier
An on-farm demonstration report from August–October 2022, evaluating dairy performance, health observations and economic calculations. Presented separately because the supplied file is a study dossier, not a complete commercial specification.
A STARTING POINT FOR
Dairy technical teams reviewing evidence and planning a comparable local evaluation.
Dairy #1 received CENFIX GOLD. Comparisons were made with the same dairy in 2021 and with a sister dairy (#2) during 2022 under reportedly similar nutrition and management. This is an observational farm demonstration; randomization is not described.
| Study period | Study administration rate |
|---|---|
| 1–8 August 2022 | 22.5 mL/head/day (24 g) |
| 9 August–31 October 2022 | 7.5 mL/head/day (8 g) |
These are the study administration rates, not a verified general-use recommendation. Obtain the current label and application sheet before commercial use.
| Parameter | Information in the supplied document |
|---|---|
| Study period | 1 August – 31 October 2022 |
| Animals / feeding groups | Close-up, fresh and high-milking pens. |
| Product composition | Not provided in the study dossier. |
| Commercial specification | Request formulation identity, concentration, packaging, storage and shelf life. CENFIX GOLD and MINGFIX GOLD are different names; their equivalence is not established. |
The two comparisons lead to different health and economic outcomes. Farm/year differences can confound results; sample size and complete animal-level data are not disclosed. The calculations use historical US component prices (fat USD 3.372/lb; protein USD 2.5374/lb). They are not a Vietnam profitability forecast or evidence of disease prevention. 1 lb ≈ 0.4536 kg.
| Measure | Dairy #1 · 2021 | Dairy #1 · 2022 | Dairy #2 · 2022 |
|---|---|---|---|
| Milk yield (lb/day) | 86.77 | 92.88 | 85.96 |
| Milk fat (%) | 4.64 | 4.48 | 4.58 |
| Fat yield (lb/day) | 3.89 | 4.00 | 3.86 |
| Milk protein (%) | 3.36 | 3.45 | 3.33 |
| Protein yield (lb/day) | 2.88 | 3.14 | 2.83 |
| Calculated milk income (USD/cow/day) | 20.42 | 21.46 | 20.20 |
| Item | Same-farm year comparison | Dairy #1 vs #2 · 2022 |
|---|---|---|
| Incremental milk income | +1.04 | +1.26 |
| Programme cost | −0.069 | −0.069 |
| Feed saving / extra feed cost | +0.243 | −0.652 |
| Net milk economic return | +1.21 | +0.54 |
| Item | Same-farm year comparison | Dairy #1 vs #2 · 2022 |
|---|---|---|
| Programme cost | −6.32 | −6.32 |
| Health-cost difference | −11.27 | +52.32 |
| Net health economic return | −17.59 | +46.00 |
High pens: +3.62 lb/cow/day versus Dairy #2 (P≤0.01). Close-up pens: +1.3 lb/cow/day in the report conclusions.
First-test milk approximately +6 lb/day; energy-corrected milk +5.5 lb/day; milk protein +0.09 percentage points (P≤0.03), protein yield +0.26 lb/day. No improvement in percentage of health events or herd exits was found.
First-test milk approximately +7 lb/day and energy-corrected milk >6 lb/day. Reported metritis nearly threefold lower, mastitis approximately 50% lower and acidosis nearly fifteenfold lower (P≤0.01). Lameness was lower (P≤0.01); stomach-problem events were lower (P≤0.02), although the report questions whether that event code remained in use. Retained placenta was not lower (P=0.94).
Per 1,000 calvings: Dairy #1 in 2022 was USD 11,268.70 higher than in 2021, but USD 52,319.50 lower than Dairy #2 in 2022.
