European reference method for the in vivo determination of metabolisable energy with adult cockerels: reproducibility, effect of food intake and comparison with individual laboratory methods.
TLDR
A common reference procedure adopted by several European laboratories to determine apparent metabolisable energy corrected to zero-nitrogen balance (AMEn) is described, and values measured by individual laboratory procedures were very close to those obtained by the reference method. Expand
European reference method of in vivo determination of metabolisable energy in poultry: reproducibility, effect of age, comparison with predicted values.
TLDR
Determined AMEn values were very similar to those predicted using three different regression equations, suggesting that AMEn energy values of these fats are indistinguishable at this inclusion rate when diets contained added fat. Expand
Metabolisable energy value of fats in chicks and adult cockerels
TLDR
The difference between ME values obtained by digestibility studies and those obtained directly showed that added fat may increase the absorbability of other constituents of the diet, hence the ME obtained by difference may exceed gross energy in some cases. Expand
Effect of autoclaving on metabolizable energy value of smooth pea seed (Pisum sativum) in growing chicks
TLDR
Calculated values of pea AMEn increases (Δ Ec) induced by autoclaving were obtained on the basis of protein and starch digestibility increases and the mean of ratios was 0.901. Expand
Evaluation of the clastogenic action of benzene by oral administration with 2 cytogenetic techniques in mouse and Chinese hamster.
TLDR
Findings that the adult male mouse is about twice as sensitive as the female to the clastogenic action of orally administered benzene are confirmed by metaphase chromosome analysis of bone-marrow cells from mice and Chinese hamsters. Expand
Evaluation of the efficacy of salinomycin in the control of coccidiosis in chicks.
TLDR
The weight gain of birds given salinomycin at 80 ppm was depressed significantly (P less than .01) at 56 days as a result of decreased feed consumption, and statistical analysis of main effects on weight gain, feed conversion ratio, hematocrit value, and serum optical density showed no significant differences between sal inomycin, monensin, or halofuginone. Expand
Method of evaluating the efficiency of anticoccidial drugs in floor-pen trials with multiple in-feed infection versus "seeding" model.
TLDR
Lesion scorings, serum coloration and hematocrits are excellent criteria to evaluate the incidence of parasitism and an experimental work plan is suggested. Expand
A methodological study of the relationship between the metabolizable energy values of two meat meals and their level of inclusion in the diet.
TLDR
It is concluded that ME of MM should be measured in diets containing low practical MM, becauseificially high experimental levels of 50 or 100% may lead to underestimation of the energy of MM. Expand
Evaluation of the effect of anticoccidial drugs on size of parasite population and its development in litters.
TLDR
It is observed that contamination varies considerably according to the anticoccidial drug present in feed, and Monensin is the one which least reduces contamination of environment; Halofuginone is theOne which reduces contamination the most. Expand
