This paper describes a standardized method for in vivo determination of total digestibility rabbits. was working out within the European Group on Rabbit Nutrition (EGRAN) which involves six laboratories from five countries (Belgium, France, ltaly, Portugal and Spain). The aim group to propose at once reliable, quick and- simple. new rnethod can be regarded as baseline calibrating individual laboratory procedures. is based 7 8 weeks old rabbits caged individually fed ad libitum....

ABSTRACT In broiler chickens, feed additives, including prebiotics, are widely used to improve gut health and stimulate performance. Xylo-oligosaccharides (XOS) hydrolytic degradation products of arabinoxylans that can be fermented by the microbiota. current study, we aimed analyze prebiotic properties XOS when added diet. Administration in addition a wheat-rye-based diet, significantly improved conversion ratio. increased villus length ileum. It also numbers lactobacilli colon Clostridium...

This review is focused on the most studied and developed substances which are commonly knownas alternatives to dietary antibiotics, particularly as far rabbit feeds concerned. After a reminder of thereason be success antibiotic growth promoters, why they lately came banned in theEuropean Union, we successively deal with probiotics, prebiotics, enzymes organic acids. Data rabbitsare, expected, quite scarce when compared species such pigs poultry. Nevertheless, theavailable performance results...

Creatine, (CREA) a central constituent in energy metabolism, is obtained from dietary animal protein or de novo synthesis guanidinoacetic acid (GAA). Especially all-vegetable diets, supplemental CREA GAA may restore the availability tissues, and hence, improve performance. In this study, 768 one-d-old male Ross 308 broilers were assigned to 1 of 4 diets: negative control, corn-soybean-based; control supplemented with either 0.6 1.2 g per kilogram feed; positive (60, 30, 30 g/kg fish meal...

The aim of this paper was to draw up a set recommendations for applied nutrition and feeding trials with rabbits, in relation certain aspects such as determining the nutritive value raw materials or diets growing reproducing animals, studying digestive physiology obtaining growth reproduction parameters. We deal first size sample, housing conditions, diets, handling, measurements, data analyses relevant design experiment are described. Secondly, we give list recommended items include some comments.

1. A field study was conducted to investigate the deterioration of eggshell quality at end lay and examine potential extend production cycle. total 1200 eggs were assessed originating from commercial farms in Belgium: random sampled collection belt 57–65 weeks age cycle (74–92 weeks).2. Based on a linear mixed model, egg estimated for an average flock 60 changes traits predicted until laying cycle.3. Egg weight increased by 0.07 g every week onwards shape index decreased 0.04 unit weekly (P...

Concerns about the environment, nutrition, and farm profits all point to increasing importance of phosphorus (P) content a diet. Animals must now be fed near their P requirements. However, it is very difficult know exact requirements broilers. The objective this study was provide efficacy data 6-phytase for use in broilers at different Ca levels Ca/P ratios. Broilers were randomly assigned 6 treatments, each with replicates. treatments comprised diets differing level: 1) normal total (Pt)...

The non-starch polysaccharides (NSPs) in cell walls can act as a barrier for digestion of intracellular nutrients. This effect is called "cage effect." Part the success fibrolytic enzymes broiler feed assumed to be attributed cage reduction. Further, changes viscosity and potential prebiotic action should also considered. aim this study was gain insight into relative importance xylanase efficacy broilers. Using 2×2 factorial design, 24 pens with 30 Ross 308 male chicks were fed corn-soy...

A pen trial using 1,080 male Ross 308 broiler chicks (6 treatments with 6 replicates each) was conducted to examine the effects of 3 dietary phytogenic products on avian coccidiosis. The included (1) a negative control (NC), (2) positive (PC) without feed additive, (3) Narasin at 0.7 kg/t (COCC), (4) PHYT1 (oregano) 2.0 kg/t, (5) PHYT2 (combination Curcuma, saponins, and inulin) 1.0 (6) PHYT3 (Quillaja) kg/t.

Broilers were randomly assigned 12 treatments, each with 6 replicates, comprising 3 diets differing level: 1) normal Ptot (NN); 2) low (NL), 3) (LL). also given 2 levels cholecalciferol phytase. for starter, grower, finisher phases 0.90, 0.82, 0.74% 0.67, 0.62, 0.57%, respectively....

In 3 preliminary trials, the effect of a dietary addition with 0.5% chestnut tannin extract, containing approximately 55% hydrolysable tannins, was examined on mortality after weaning. The tannin-enriched diet fed to does and their litters from 22 days lactation. After weaning (day 29), young rabbits did not change treatment remained control or diet, respectively. total 1217 were considered, about half whom diet.
