THE EFFICIENCY OF THE UTILIZATION OF ELEMENTARY SELENIUM ADDITION TO THE RATIONS FOR CHICKENS

Almost all off the fodders don't provide necessity in selenium. Micro supplements of selenium salts into chicken’s ration favor stimulation of growth. Necessity in producing of mixed food with supplement of selenium for chickens are obvious. In order to study the efficiency of the utilization of selenium addition in the chicken rations we have done a scientific and farm experiment. During the experiment an addition of selenium at the level 0.25mg/kg of dry substance with fodder and water was added to the rations of the chickens in the experimental group. The data on the live mass have shown that the live mass of the chickens in the experimental groups was greater in comparison with that in the control group. In our experiments, in using selenium supplements in mixed food for quick-growing chickens we also got positive results in body mass, spending of fodders and preservation, but it is necessary to continue research

SPECIAL FEATURES THE FEEDING OF YOUNG OSTRICHES UNDER THE CONDITIONS OF THE REPUBLIC OF MOLDOVA

There was analyzed and compared the nutritional posture of the young ostriches of different ages, reside at the farm “Anataction Investagro SRL” in conditions of Republic of Moldavia with offered pastures based on different normative dates and there was held the comparative analysis on the contends of food-value substances in them

The Influence of the Preparation Primix Bionorm K on the Digestibility of the Nutrients in the Fodders for Young Pigs

The study was carried out in order to determine nutrient digestibility in breed gilts under the influence of the supplementation of the mixed fodder with the preparation pro-prebiotic Primix Bionorm K at the level of 0.15, 0.30, and 0.45 kg/t. During February 2011, in a digestibility trial which lasted 13 days 12 similar piglets were used, which were randomly divided into four experimental groups (CG, EG1, EG2, EG3) three heads each. It was established that the supplementation of the mixed fodder for young gilts with the preparation pro-prebiotic Primix Bionorm K had a positive influence on the digestibility of the dry and organic substances by 0.86% and 1.18%, crude protein, fat and cellulose showed a digestibility of 0.57, 1.05 and 12.37% respectively higher in EG3 compared to CG. However, the addition of pro-prebiotic preparation during the growth period of the breed gilts at the level of 0.45 kg/t (EG3) allowed obtaining an absolute increase in body weight during the digestibility trial by 8% higher than in the CG and EG1

The Effect of the Adsorbent Primix-Alfasorb on the Morphological and Biochemical Blood Parameters of Breeding Gilts

The studies were conducted at the state enterprise “Moldsuinhibrid” (Republic Moldova) in 2011 using piglets of Landrace breed. The animals selected for the experiment on the basis of analogues (including origin, age, body weight and health status) were divided into four groups of 10 animals each. The basic diet for the piglets in the experimental groups was supplemented with the adsorbent Primix-Alfasorb at the level of 0.2, 0.4 and 0.6 kg per ton of mixed fodder. It was established that the addition of the adsorbent Primix-Alfasorb in the mixed fodder had contributed to the increase in body weight in different age periods; to the end of the trial the live weight of the piglets in groups EG1, EG2 and EG3 was higher by 8.72, 5.83, and 7.93 % compared with the control group. The analysis of the blood of the experimental animals the diet of which was supplemented with the adsorbent Primix-Alfasorb, showed that all parameters were within the physiological norm, and the increase in the amount of total protein indicated a strengthening of the metabolic processes in the animals. It was determined that the optimum level of the addition of the adsorbent Primix-Alfasorb in the mixed fodder for piglets was of 0.2 kg/t
