The report describes control, LIVEBIOS and MINGFIX groups of 15 piglets each, observed from June to November 2002. It gives 2 kg/t during the first month and 1.5 kg/t subsequently, with two starting-weight cohorts. These are study rates, not current label instructions.

The author reports higher growth and changes in carcass and meat traits. The report’s descriptions of cohorts and some units are imprecise; review the full tables and protocol before calculating a commercial response.

Fifteen animals per group, starting at 45 days. The probiotic trial used 2 kg/t and the separate phytobiotic trial 120 g/t. Diet composition, weight gain, carcass output and physicochemical meat properties are reported.

Reported daily gain was 20.3% higher for LIVEBIOS and 18.0% for MINGFIX versus control. Carcass-output differences were not statistically significant (P>0.05). Separate phytobiotic results must not be attributed to the Biofeed formulations. Results describe this historical trial, not a guaranteed farm outcome.

378 male and female Ross 308 chicks; seven treatments with three replicate pens of 18 birds (nine male and nine female). The study compares a control and six supplementation windows across days 1–42.

The authors report effects on intestinal Bifidobacterium, total aerobic counts and selected blood measurements, and favour whole-period supplementation in their conclusion. These endpoints do not by themselves establish disease prevention or a particular feed-conversion saving.

60 Holstein-Friesian cows in two groups on identical diets. The trial group received 10 g LIVEBIOS per cow daily from 15 days before calving through day 60 of lactation. These are the historical study conditions.

Table 2 reports mean 4% fat-corrected milk of 29.55 kg for control and 32.12 kg for treatment, a 2.57 kg difference. The paper gives inconsistent percentage descriptions (8.70% in the abstract and 10.86% in the discussion). Use the table values and request clarification before reusing a percentage claim.

120 Hybro-PN broilers, two groups of 60, followed from day 1 to day 56. The trial group received LIVEBIOS at 2 kg/t feed. Ten representative males per group were sampled at day 56 for carcass and meat measurements.

Table 1 reports day-56 body weights of 3,471 g versus 3,831 g and whole-period FCR of 1.78 versus 1.62 (control versus LIVEBIOS). The abstract and discussion use different body-weight percentage descriptions, so retain the raw values and study conditions when discussing the result.

Ross 308 chicks in two treatment groups, each with four pens of 75 birds, on a corn/soybean diet to day 42. BioLAC was used at 1 kg/t. Eight birds per group were sampled for intestinal measurements, with at least 15 measurements per parameter per bird.

The report finds significant differences in several morphology measures. These are tissue-level endpoints; they should not be converted directly into a guaranteed FCR or disease-prevention claim.

Two groups of 35 birds. Control birds received a non-toxic basal feed; the trial group received feed described as slightly toxic with MINGFIX at 2 kg/t in the first growth period and 1 kg/t in the second.

Reported FCR was 1.85 for control and 1.76 for the trial group; day-42 weight was 2,477.4 g and 2,529.2 g respectively. Because feed quality and supplementation both differed, this comparison does not isolate the effect of MINGFIX alone. The report does not establish a current dose for Vietnam.

A table for yearling horses compares control versus control plus LIVEBIOS: dry matter 70.2% versus 76.6%; acid-detergent fibre 59.5% versus 67.8%; neutral-detergent fibre 55.8% versus 69.5%; hemicellulose 53.5% versus 65.1%; total nitrogen 52.9% versus 55.3%.

The two-page article does not provide a full sample-size, dose or statistical protocol beside the table. Treat it as a historical technical discussion and request the underlying trial before estimating a response.
