Hyperxanthinuria and xanthine uroliths have been recognized with increased frequency in dogs with ammonium urate uroliths that had been given allopurinol. We hypothesized that dietary modification might reduce the magnitude of uric acid and xanthine excretion in urine of dogs given allopurinol. To test this hypothesis, excretion of metabolites, volume, and pH were determined in 24-hour urine samples produced by 6 healthy Beagles during periods of allopurinol administration (15 mg/kg of body weight, PO, q 12 h) and consumption of 2 special purpose diets: a 10.4% protein (dry matter), casein-based diet and a 31.4% protein (dry matter), meat-based diet. Significantly lower values of uric acid (P = 0.004), xanthine (P = 0.003), ammonia (P = 0.0002), net acid (P = 0.0001), titratable acid (P 0.0002), and creatinine (P = 0.01) excreted during a 24-hour period were detected when dogs consumed the casein-based diet and were given allopurinol, compared with the 24-hour period when the same dogs consumed the meat-based diet and were given allopurinol. For the same 24-hour period, urine pH values, urine volumes, and urine bicarbonate values were significantly (P = 0.0004, P 0.04, and P = 0.002, respectively) higher during the period when the dogs were fed the casein-based diet and given allopurinol than when they were fed the meat-based diet and given allopurinol. Endogenous creatinine clearance was significantly (P = 0.006) lower when dogs were fed the casein-based diet and given allopurinol than when they were fed the meat-based diet and given allopurinol. Significantly lower concentrations of plasma uric acid (P 0.0001), plasma xanthine (P = 0.01), and serum urea nitrogen (P = 0.0001) were detected when dogs consumed the casein-based diet and were given allopurinol than when they consumed the meat-based diet and were given allopurinol.

In this study five samples each of serum glucose, serum cholesterol and uric acid contents were measured in Fayoumi, Rhode Island Red, Parent desi, desi Fl and desi F2 strains of chickens. Cholesterol contents were found to be lowest in desi F2 chickens whereas in other strains there was least significant difference, which can be attributed to reduced lipogenic activity in desi F2 generation. When five samples each of meat from two locations i.e. breast and thigh was subjected to proximate analysis it was found that there was no difference (P greater than 0.05) in crude protein, crude fat, total ash and moisture contents regardless of sex and strains. Dry matter contents differed (P less than 0.05) in breast meat and found to be lowest in Parent desi stocks.

This trial was conducted to study effect of freezing on quality of broiler meat after freezing. Meat samples were taken from two sites such as breast and thigh. The weight, moisture, protein, fat and ash contents were analyzed before and after freezing at -25 degree centigrade for 15 days using methods given in AOAC, (1990). It was observed that protein, fat and ash contents were not changed consequent to freezing. There was loss (P less than 0.05) in weight which can be attributed to drip loss when meat is thawed. This study provided evidence that there is no change in nutrients when meat is subjected to freezing.

Studying of efficiency of application of a natural biological control agent BioLAD obtained as a result of cultivation of Fusarium sambucinum fungus in feeding of broiler chickens was realized in the conditions of the Republic of Belarus. There were studied 100 broiler chickens of Ross-308 cross. Broiler chickens of the first (control) group were fed with standard diet with PK-5-1. Broiler chickens of the experimental groups starting from one day old age till the end of the growing period (41 days old) were fed with feed supplement BioLAD in different doses: 0,25 ml/head (second group), 0,5 ml/head (third group), 1 ml/head (fourth group). Research results showed that natural biological control agent BioLAD in dose of 0,5 ml/head made it possible to increase chicken live weight on 11,2 %, viability - on 4,2%. Feeding charges per 1 kg of live weight gain were1,89 kg (second group), 1,81 kg (third group), 1,90 kg (fourth group). It made it possible to decrease the combined feed charges on 6,4% (second group), on 10,4% (third group), and on 5,9% (fourth group). Application of biological control agent BioLAD had an effect on poultry growth activity, promoted high level of chickens viability, increased the indices of general and local protection, stimulated metabolic processes

Research of the influence of biologically active preparations of natural origin on zoological indices and quality of animal products was studied by the example of their application in broiler chicken diets in the conditions of the Republic of Belarus. On the basis of realized research it was established, that application of biologically active substances immunoamplifier Alveozan, probiotic Dialakt, probiotic Bifidoflorin liquid, prebiotic Biofon and prebiotic Biofon AIL (produced in the Republic of Belarus) did not render negative effect on quality of animal products (all studied meat samples had high quality). The received results testify to necessity of complex application of the above-stated preparations. Application of biologically active preparations made it possible to increase livability of growing birds on 100%, average live weight increase from 1,9 up to 5,1%, daily average weight gain - from 1,9 up to 5,1%, improvement of feed conversion ratio - from 18,3 up to 21%. All studied biologically active preparations made it possible to restore the physiological environment in poultry intestines, normal flora, to suppress the growth of pathogenic microorganisms. The above mentioned preparations could be applied both with preventive, and with the medical purposes

In article results of studying of efficiency and quality of poultry-fanning production under influence chitosan are considered. It is established that the preparation promotes safety increase on 0,5%, efficiency on 6% and biological value of meat on 20% at chickens whom gave to drink chitosan in a dose of 5 mg/goal from 32 day age it) comparison with the control. Such technological reception leads to decrease the receipt in an organism of a chicken of microtoxins, heavy metals, products of a metabolism of bacteria

In the conditions of the Republic of Belarus there was studied the veterinary and sanitary quality and safety of poultry slaughter products after application of a natural biological corrector VitoLAD produced in Belarus on the basis of cultivation of nonpathogenic strain of fungi Fusarium sambuninum MKF-2001-3 used for restoration of dysfunction disorders. As a result of the realized bacteriological research there were marked no pathogenic and opportunistic organisms in all experimental samples of meat and internal organs. Indices of biological value of meat of three experimental and control group had no authentic differences. Displays of toxicity for infusorians were not marked. Poultry meat of investigated samples in control, and all three experimental groups (doses of 0,25 ml/head - the second experimental group, a dose of 0,5 ml/head - the third experimental group and a dose of 1 ml/head - the fourth experimental group) in diets of which there was added the natural biological corrector VitoLAD, proved to be good-quality and harmless. In accordance with organoleptic, physical and chemical, bacteriological indexes, as well as biological value and harmlessness did not concede to meat of the control group. The complex veterinary and sanitary estimation of bird carcasses of three experimental and control groups did not show any deviations from existing standards that made it possible to organize production realization without restriction.
