Three experiments were conducted to test the effects of Lipo-adrenal cortex (LAC), cortisone acetate (CA), hydrocortisone acetate (HCA) and glucagon (G) in broiler chickens. Oral administration of 38.7, 69.6 or 96.8 mg CA per bird significantly retarded body weight gain between days 14 and 21. HCA administered intramuscularly in doses varying from 2 to 24 mg/100 g of body weight significantly decreased body weight gain between days 14 and 28. Shank growth was similarly affected by doses over 4 mg HCA. The same doses significantly increased liver weight. At 3 months of age, birds recovered from growth retardation caused by the injection of 4 mg HCA/100 g of body weight at 14 days of age. Experimental results indicate that 2 or 4 mg HCA/100 g of body weight, administered by one injection at 14 days of age, may be used to increase growth rate variance by retarding growth.

The objective of the study was to evaluate feeding effect of microparticle protein derived from soybean meal and fish meal combined with Lactobacillus sp. at 1.2 mL on physiological condition of digestive tract and productivity of broiler. Total of 192 broiler, with initial body weight was 481.0 ± 67.2 g, given dietary treatment starting on day 21 until day 42. The experiment was assigned in a completely randomized design with 8 treatments and 4 replications. Dietary treatment were 21% intact protein (T0), 18% intact protein (T1), 21% microparticle protein (T2), 18% microparticle protein (T3), T0+Lactobacillus sp.1.2 mL (T4), T1+Lactobacillus sp.1.2 mL (T5), T2+Lactobacillus sp.1.2 mL (T6), T3+Lactobacillus sp.1.2 mL (T7). Parameters measured were total ileal lactic acid bacteria (LAB), Coliform and pH, rate of passage, daily body weight gain (DWG) and also carcass weight. Data were subjected to analysis of variance and followed by Duncan multiple range test (P<0.05). Experimental results showed that microparticle protein diet added with Lactobacillus sp. (P<0.05) increased total LAB and DWG, but decreased Coliform population, and slowed down the rate of passage. However, carcass weight was not significantly affected by treatments. Feeding microparticle protein (18%) with addition of Lactobacillus sp. (1.2 mL) can improve to be better condition of digestive tract based on higher LAB and lower Coliform populations, and increase daily body weight gain with the same carcass weight.

Poultry farming holds a special place in ensuring the products that the consumers demand, it provides the population with essential food products,such as eggs and meat,that contain vital micro and macronutrients, proteins, lipids, and vitamins. Therefore, the issues of rational, economically feasible feeding of meat poultry, namely broiler chickens, are an urgent task. It is also essential to find effective methods of their application in order to correct the natural resistance and immune and biological reactivity of birds. The purpose of this research is to study the effect of the biological stimulant-Nucleostim on the growth and development of chickens, hematological, and immunological parameters of the blood of birds.This Biostimulant is a purified bovine spleen extract containing at least 1 mg / ml of low molecular weight peptides (nucleotides and nucleosides) formed as a result of autolysis, using dry whey and diatomite as fillers. Onthe application ofNucleostim, the gain in live weight of chickens was increased by 9.7%. At the end of the experiment, the livability of the chicks of the experimental group treated with Nucleostimcame up to 88%, compared with the 72% of the control group. The use of biostimulant had a stimulating effect on the liver of chickens confirmed by the research results presented in the article, as well as contributed to the development of the thymus in the setting of general dystrophy. Thus, it improved chicklivability and increased body weight gain. The biological stimulant-Nucleostim as an adaptogenic, anabolic, and immunostimulatory agent is promising for finding new drugs that improve the health and productivity of poultry.

Rate Of Development

A restricted index selection experiment on mice was carried out for 14 generations on rate of early postnatal development (growth rate from birth to 10 days of age) vs. rate of development much later in ontogeny (growth rate from 28 to 56 days of age). Early rate of development (E) approximates hyperplasia (changes in cell number) and later rate (L) reflects hypertropy (changes in cell size). The selection criteria were as follows: E+L0 was selected to increase early body weight gain while holding late body weight gain constant; E–L0 was selected to decrease early body gain while holding late gain constant; E0L+ was selected to increase late gain holding early gain constant; and E0L– was selected to decrease late gain holding early gain constant. After 14 generations of selection, significant divergence among lines has occurred and the changes in the growth trajectories are very close to expectation. The genetic and developmental bases of complex traits are discussed as well as the concept of developmental homoplasy.

The combined effect of homobiotics, probiotics based on recombinant strains of g. Bacillus, & enrofloxacin on the dynamics of body weight gain in geese was studied. According to the principle of steam-analogs, one control and five experimental groups of 10 goslings in each group were formed. Gosyatam experimental groups used homobiotics vetom 15.1; vetom 13.1 incombination with enrofloxacin followed by replacement with a probiotic preparation Vetom 1.2. The absolute body weight and average daily gain in geese under the influence of the studied drugs increases. The severity of the effect depended on the pharmacological composition of the drugs used. The maximum absolute weight gain was observed when using the drugs according to the scheme: vetom 13.1 at doses of 25–50 mg/kg for 16 days, with further use of a 10% enrofloxacin solution at a dose of 0.5 ml/kg for 5 days and in The experiment period was 1.2 at a dose of 50 mg/kg for 16 days. After the cessation of the use of drugs, the growth rate increased for 30 days when prescribing the drugs according to the scheme: veto 13.1 at a dose of 50 mg/kg for 16 days and with further introduction of homobiotic veto 1.2 into the bird in a dose of 50 mg/kg for 16 days. The maximum average daily gain in live weight of geese was observed in the period from the 16th to the 32nd day with the administration scheme: homobiotic vetom 13.1 at a dose of 25 mg/kg of body weight 1 time per day for 5 consecutive days, then every other day for 16 days, then daily 10 % solution of enrofloxacin at a dose of 0.5 ml/kg of body weight for 5 days, then vetom 1.2 at a dose of 25 mg/kg once a day for 16 days in a row. And the maximum average daily gain in the post using period of the drug was observed on the 32nd day of the study according to the scheme: homobiotic veto 15.1 at a dose of 50 mg/kg of body weight 1 time per day for 16 days, then daily with vetom 1.2 at the same dose 1 once a day for 16 days. The studied drugs in the applied doses did not have a toxic effect on the physiological state of geese.

Two trials were conducted with Nicholas strain turkeys. In trial 1, 300 male poults were reared to 49 days using either initial stages of 'large-turkey' feeding regime, or a situation allowing for diet self-selection of protein and energy. Within these programs, diets were supplemented with 10 ppm avoparcin, while a comparable number of controls received no growth promoter. Avoparcin improved growth rate (P < 0.01) irrespective of age, and improved feed utilization to 35 days of age. This effect was not confounded with the form in which diets were offered. In a second trial a 'broiler-turkey' feeding schedule was used, with birds slaughtered at 88 days. Diet treatments consisted of a control diet containing 33 ppm robenz and test diets containing either 33 ppm robenz + 10 ppm avoparcin or 10 ppm avoparcin alone. Avoparcin improved weight gain (P < 0.05) irrespective of coccidiostat inclusion. Feed utilization and carcass grades were not influenced by diet. The 7% improvement in body weight noted here with avoparcin was substantially greater than that previously observed with broiler chickens.

Abstract. Serum levels of somatomedin A, as measured by radioreceptor assay, and body weight gain were 86.5 ± 9.2% and 166.9 ± 7.8% (N = 5) of the initial values, respectively, after 18 days administration of 2.5 mg cortisone acetate (CA). These values were significantly lower than those for saline treated rats (P < 0.005). Reduced serum somatomedin A and body growth rate were partially restored after halting the injection of CA. Combined administration of daily doses of 100 μg hGH with CA did not prevent the decrease in somatomedin activity in treated rats. This observation suggests that GH plays a minor (or no) role in the fall of serum somatomedin A in CA-treated rats. From these data we conclude that glucocorticoids reduce serum somatomedin by inhibiting the effect of GH on the generation of somatomedin.
