<p>The authors have investigated the effect of different levels guanidinoacetic acid in the diets of quails on their productivity and carcass quality. Experimental studies were carried out in the conditions of the problematic research laboratory of feed additives in the National University of Life and Environmental Sciences of Ukraine. Material for scientific and economic experience was quail of Pharaoh species of meat direction of productivity. The experiment was carried out by method of groups-analogues. Compound feed were fed in dry crumbled form. Young animals were fed in a group. The daily amount of compound feed was divided in two parts – morning and evening rations. The effect of using different levels of Guanidinoacetic Acid (GAA) in compound feed on productivity and carcass quality of young quails was studied. We have found that compound feed with the level of GАА 0.06% contributes to live body weight increase by 3.9 g and muscles of the pelvic limbs yield by 26.2%. At the same time, use of diets with a level of 0.12% of guanidine acetate increases live weight by 13.5 g, the absolute growth of 6.5 g, average daily growth by 0.9 g, a relative growth of 2%, the mass of carcass, semi-eviscerated carcass, and eviscerated carcass of 4.8, 4.9 and 4.3% correspondingly, slightly increases the mass of pectoral muscles by 9.1%, significantly increases the yield of muscles of the pelvic limbs by 36.4%, and reduces feed conversion by 5%. Poultry which was fed with 0.18% of GАА exceeded control of body weight by 12.2 g, the absolute growth by 4.4 g, average daily growth by 0.6 g, the relative growth by 1.1%, yield of muscles of the pelvic limbs by 36.4% and  had a lower feed conversion rate by 9.1%. During the study period the safety of livestock which was fed with GААvwas high and ranged from 90 to 96%.  It was established the perspective of further research, which is to examine the impact of Guanidinoacetic Acid on the egg production of egg-laying quails, morphological and chemical composition of eggs and  their hatching  quality.</p>

The objective of this work was to evaluate performance, efficiency parameters and phenotypic correlations among measurements of energy efficiency of Nellore cattle selected for post weaning weight and classified according to residual feed intake, calculated by the difference between observed and predicted intake, based on average metabolic body weight and average daily gain. Thus, animals were classified within three groups: high (> mean + 0.5 standard deviation, less efficient); medium (±0.5 standard deviation of the mean); and low (< mean - 0.5 standard deviation, more efficient) residual feed intake. No differences were observed at initial and final body weights, average daily gain and dry matter intake among groups. Animals with low residual feed intake also had greater feed efficiency, feed conversion and partial efficiency of growth and did not differ from the other animals regarding to relative growth rate and Kleiber ratio. Residual feed intake was significantly correlated to feed efficiency (-0.25), feed conversion (0.25), partial efficiency of growth (-0.37) and dry matter intake (0.16) but it did not present significant correlation with body weight (0.04), average daily gain (-0.02), relative growth rate (-0.03) and Kleiber ratio (-0.05). Significant correlations were found between feed conversion and initial body weight (0.34) and average daily gain (-0.46). Partial efficiency of growth presented significant correlation with all other efficiency parameters analyzed. Residual feed intake has high potential in productive efficiency, when compared to the other energy efficiency measurements, being independent of growth and size of the animals.

Sixty 7-week-old New Zealand White rabbits were randomly distributed into 5 equal experimental groups. The experimental rabbits were fed the tested diets till 14 weeks of age during summer season. The basal diet without feed additives (control; T1) and the other experimental diets were supplemented with enzymes at 0.5 g/kg (T2), organic acids at 1.0 g/kg (T3), Beta-pro at 0.2 g/kg (T4) or their combination (T5). The criteria of response were body weight, weight gain, feed consumption, feed conversion ratio, some blood constituents, carcass traits and economic efficiency. The obtained results can be summarized as follows: Positive effects of feed additives were observed on live body weight, daily weight gain and feed conversion of growing rabbits. There were no significant effects on blood parameters or carcass traits due to feed additives. It can be concluded that dietary Beta-pro (enzymes+probiotics) or a combination of enzymes, organic acids and Beta-pro at the tested levels can be used to improve the rabbit performance, with no adverse effects on carcass characteristics or blood parameters.

The effect of using different levels guanidinoacetic acid in compound feeds on the growth of young quails meat direction of productivity. It is proved that adding to the basic diet of different levels guanidinoacetic acid (0.06, 0.12, 0.18 %) increases live weight of quails on 3.9 – 13.5 g and improves the absolute, average daily and relative gains compared to a bird in the control group, which were fed the main diet. The data show that at the age of 42 days of live weight was the highest in the diet of quail which was administered 0.12% GAA and dominant control of 13.5 g However, in 21 days live weight of quail fed 0.06 and 0.12 % guanidinoacetic acid was greater than control respectively 9.2 and 7.6 grams (P < 0.01). In absolute increments quail, fed GAA prevailed bird control group. The largest absolute increase was in birds that consumed the main diet of GAA level of 0.12% and prevailed controls 6.5 g (P < 0.001). A similar situation was of average daily gain. Young animals that received feed containing 0.12% guanidinoacetic acid had the highest average growth, which exceeded 0.9 g (15.5%) bird control group. As for the relative performance increases here were different. The lowest relative growth observed in birds which were administered GAA 0.06%, it lagged behind the controls 0.1 g in the same period quail treated with 0.12 and 0, 18% guanidinoacetic acid superior control respectively 2 and 1.1 g.

Abstract. The purpose of the research is to develop an effective feed additive with an optimal content of raw protein in combination with flavoring additives for ducklings, which allows to increase zoo technical and economic indicators with broiler technology of fattening young animals. Research methods. A scientific and production experiment was conducted on three groups of analog ducklings from a daily age to 49 days old. The studied indicators are: the dynamics of live weight by fattening phases, absolute and average daily growth, the safety of young animals, feed conversion, slaughter indicators, the European fattening efficiency indicator, the profitability of meat production. Results. The use of compound feeds with an optimal level of protein content in combination with flavoring additives prepared on the basis of developed feed additives intended for fattening broiler ducklings in the fattening phases contributes to an increase in: live weight by 11.4 %, the safety of young animals by 3 %, feed consumption and conversion by 3.9 and 7.6 %, slaughter yield of 1.1 %, the European fattening efficiency indicator from 246 to 308 units and the profitability of meat production by 24.5 %. Scientific novelty. For the first time, a complex feed additive has been developed, which, according to the age periods of fattening, includes three varieties: “Prestart”, intended for intensive fattening of young animals from daily to 10 days of age inclusive, “Start” for ducklings from 11 to 21 days and “Finish” from 22 to 49 days. The rate of introduction of the additive is 30 % of the mass of mixed feed. The composition of the supplement includes high-protein feeds, premixes, amino acids and flavoring substances (monosodium glutamate, acetic and citric acids, a mixture of phytogenics: oregano, cinnamon, red pepper).

Feeder Space

The effects on broiler performance of different floor, waterer, and feeder spaces and light treatments were estimated. Increased bird density resulted in a reduction in body weight, poorer feed conversion, reduced carcass quality and a reduction in monetary returns per bird started. Feeder space effects were inconsistent. Waterer spaces examined had little effect on bird performance. Light treatments studied revealed that cycles of 1 h of light with 3 h of darkness resulted in slightly superior feed conversion compared with cycles of 3 h of light and 1 h of darkness.
