this experiment was conducted to investigate the effect of phytase superdoses alone or in combination with citric acid (ca) in canola meal-based diets severely limited in available phosphorus (pa) on growth performance, plasma phosphorus (p), and tibia ash (ta) in broilers from 22 to 42 d of age. two hundreds and eighty 21-d-old male broilers were used in 28 pens of 10 birds per each. the exper...

Supplementing women's diets with 400 mcg folic acid every day reduces the incidence of neural tube defects in their offspring by up to 72%. Optimizing diabetic glucose control prior to conception is linked to a reduction in birth defects and pregnancy loss. Limiting caffeine consumption to no more than 200 mg per day may reduce the risk of miscarriage.

(a) Acceptable daily intake (ADI). The ADI for total residues of virginiamycin is 250 micrograms per kilogram of body weight per day. (b) Tolerances—(1) Swine. Tolerances are established for residues of virginiamycin in uncooked edible tissues of 0.4 part per million (ppm) in kidney, skin, and fat, 0.3 ppm in liver, and 0.1 ppm in muscle. (2) Broiler chickens and cattle. A tolerance for residue...

Two hundred 1-day-old commercial broilers (Ross 308) were used to determine the effects of diets supplementation with waste date’s vinegar (WDV) on the growth and performance of digestive tract over a 42-days growing period. Chicks were randomly allocated to one of five experimental diets supplementing as 0 (control), 1, 2, and 3% of WDV and 2% industrial vinegar (IV). Broilers and their feed c...

This research was conducted to compare the effects of two medicinal plants (peppermint and aloe vera) and antibiotic growth promoter on ileum microflora population and growth performance of broiler chickens. In this experiment, 375 one-day old male broiler chickens (Ross 308) were used on a completely randomized design with 5 dietary treatments which were replicated 5 times with 15 birds per re...

The two components of virginiamycin, M and S, separately exerted a reversi ble bacteriostatic activity on Bacillus subtilis. Their combination increased by a hundredfold the inhibitory activity of each factor and induced a loss of viability of bacteria. Such an irreversible step was preceded by a reversible phase, which was characterized by a long lag in colony formation. Very short incubation ...
