Abstract

The results of research on the use of grain mixtures of different composition made in the Polissya area of Ukraine (%): No. 1 (wheat – 75, lupine – 10, mixed feed – 15), No. 2 (wheat – 55, triticale – 20, lupine – 10, mixed fodder – 15), №3 (wheat – 35, triticale – 40, lupine – 10, mixed feed – 15) when growing and fattening young pigs. It was found that the replacement of 20–40% (by weight) of wheat in the composition of grain with the corresponding amount of triticale in animal diets adversely affects their productive qualities (by 9,5–10,3%) and increases the feed costs per unit of production by 10,1–10,6%. The difference in the live weight of young pigs between the control and experimental groups at 2 months was 0,4–2,0 kg (0,6–2,9%), at 3 months – 1,4–4,7 kg (1,6–5,8%), in 4 months – 5,8–6,8 kg (5,7–6,8%), in 5 months – 8,0–8,3 kg (6,9–7,1 %) (P <0,95). The average daily growth in the live weight of animals of all experimental groups ranged from 480 g to 535 g during the period of research. The highest growth rate was observed in the youngest pigs of the first (control) group – 535 g. On the basis of the feed costs per 1 kg of the increase in the live weight, the animals of groups II and III (experimental) also yielded to the young from the control group 0,55–0,58 fodder units (10,1–10,6%) and 8,1–11,3 MJ of exchange energy (by 16,3–22,7%). Expenditures of digestible protein per unit of increment ranged from 572–658 g and were higher in piglets of research groups by 12,4–15,0% than in controls. An insignificant intergroup difference in the weight of the carcass and the slaughter weight of the young pigs was established. These parameters in piglets I (control) group were higher, respectively, by 5,0–7,5 kg (by 5,7–8,9%) and 6,15–8,15 kg (by 6,3–8,5%) than in II and III (experimental) groups. It should be noted that both absolute and relative liver weights were higher in pigs I (control) group, in comparison with II and III (research) groups – by 0,21 kg and 0,06% (absolute) and 0,40 kg and 0,24% (absolute), respectively (P <0,95). A similar trend is also observed in the absolute weight of the heart. Thus, this indicator in experimental group animals was 0,03 kg lower than in control without a significant intergroup difference. At the relative weight of the heart, all experimental animals were on the same level – 0,35%. We also did not establish significant intergroup differences in the weight of lungs, kidneys and spleen in experimental piglets.
