BACKGROUND Recent nutrition recommendations advocate a reduction in protein from animal sources (pork, beef) because of environmental concerns. Instead, protein from vegetable sources (beans, peas) should be increased. However, little is known about the effect of these vegetable protein sources on appetite regulation. OBJECTIVE To examine whether meals based on vegetable protein sources (bean...

The high voltage discharge generated by electric eels is a powerful predatory weapon. A new study shows that eels exploit basic physics to increase the voltage delivered to prey, inducing muscle fatigue that turns challenging prey items into easy targets.

Groups of 30 rats each were fed 1 of 4 diets to determine feeding preference for freeze-dried meal compared to dry meal, and to determine if 3% agar is a desirable component of freeze-dried meal. The diets were: dry meal, meal + distilled water(freeze-dried), meal + 3% agar in distilled water(freeze-dried), and meal + 3% agar in distilled water(gel). Diet preparation, and the method for introdu...

Sixteen Bonsmara calves (4 males, 12 females) between 10 and 18 months of age were blocked according to age and sex and randomly assigned to 2 groups. They were offered licks containing bone meal and salt (50:50 ratio) (control) and bone meal and ammonium sulphate (NH4SO4) at 1.25, 2.5, 5, 10, 15, and 18% (treatment) to evaluate the effects of dietary anions on bone phosphate (P) concentration....

1. The effects of chronic ethanol administration on the metabolism of ethanol and acetaldehyde were studied in rats fed on a commercial diet containing an aldehyde dehydrogenase inhibitor, calcium cyanamide (calcium carbimide), as a contaminant in the calcinated bone-meal fraction of the diet. 2. Rats given an ethanol solution (150 ml/l) for 3 months and fed on a diet containing calcinated bone...

Two experiments were conducted using direct method to determine the standardized ileal phosphorus (P) digestibility coefficient (SIPDC) of meat and bone meal (MBM) poultry byproduct (PBM) for broilers. In first experiment, three MBM from different batches evaluated, with four treatments (MBMI, MBMII, MBMIII, a P-free diet) nine replicates seven birds each, totaling 252 distributed across comple...

In this study, we screen the proteolytic activity of Bacillus species in meat and bone meal (MBM) investigate effects fermented MBM–soybean products (FMSMPs) on growth performance broilers. Trial 1, FMSMPs were using four strains—Bacillus siamensis M3 (M3), B. velezensis M5 (M5), subtilis M6 (M6), M20 (M20)—all which presented more total peptides higher degrees hydrolysis (DH) than var. natto N...

A study was undertaken on lucerne (LUC), ryegrass (RG), kikuyu (KIK), soybean meal (SBM), wheat grain (WG) and meat and bone meal (MBM) to determine the effect of animal species (sheep versus cattle) on in sacco degradation of dry matter (DM) and protein. The approach of cubic smoothing splines ®tted as a linear mixed model was used for the analysis of degradability of DM and protein of feeds. ...
