Abstract:

The quality of compound feeds used in livestock diets could be enhanced by means of domestically produced pulses. Nevertheless, there are available few research studies that would allow us to identify the economic efficiency of livestock diets with pulses and the digestibility of protein by livestock for deer farming. Accordingly, the present research aims to identify the economic efficiency of diets supplemented with domestically produced pulses – faba beans, peas and lupine beans – for captive deer. The research conducted a feeding experiment on captive deer (Cervus elaphus) kept in fenced areas to identify the economic efficiency of diets supplemented with three legume species: peas (variety ‘Vitra’), faba beans (variety ‘Fuego’) and narrow-leaved lupin seeds (variety ‘Boregine’). Deer productivity was assessed by live weight, live weight gain, feed intake and protein efficiency ratio during the experimental period, as well as feed cost per live weight gain unit. The research found that feeding deer diets containing peas, faba beans and lupine beans as protein-rich feedstuffs was economically advantageous – at the same cost of feed, deer productivity increased and per-unit production costs decreased. Live weight gains during the experimental period were 1.02% higher in group 2 (pea diet), 1.78% higher in group 3 (faba bean diet) and 2.91% higher in group 4 (lupine diet) than in the control group. During the experimental period, the highest protein efficiency ratio was found in group 4 fed a diet containing lupine beans – a unit of protein fed (1 kg) yielded the highest weight gain or 0.43 kg. Feed costs per kg of live weight gain were the lowest in group 4 (2.32 EUR kg^-1), 2.48 EUR kg^-1 in group 3 and 2.70 EUR kg^-1 in group 2, which was 20.56%, 14.81% and 7.39%, respectively, lower than those in the control group.

Abstract:

Technological stresses affect the productivity of broiler-type chicken and are related directly to poultry farming intensification. Heat stress occurring in conditions of high density keeping, especially at high summer ambient temperatures, is very important. Stress factors influence the metabolic processes in poultry, while reducing the production parameters of operation and, by extension, the efficiency of broiler farming.
The objective of this research was to identify the efficiency of a feed supplement in alleviating technological stresses in poultry industry.
Use of supplement (the preparation contains succinic acid, L-carnitine, betaine, inorganic salts of zinc, manganese, copper and lithium) preserved the production performance of broiler-type chickens in the pre-slaughter period, by reducing the technological load on the poultry body, as it was indicated by an increase in the efficiency of fattening by 16.2 conditional units, meat yield by 1.4%, gross income by 49.2% and a decline in mortality rate by 1.5%. The data on production efficiency indicators of broiler feeding were obtained on a large sample – 6136 heads.

Abstract:

Managing farming inputs in wheat production technologies is an issue of paramount importance to attain optimum profitable production. To examine how varying the farming inputs affects the nutrients uptake and productivity of spring wheat (Triticum aestivum L.) cultivars and to determine the economic efficiency of various cultivation technologies, three-year field experiments were laid out at the Russian Research Institute of Agriculture, during the 2015–2017 growing seasons. Experiments were conducted once a year using randomized complete block arranged in a split plot experimental design with three replications, with the cultivation technology treatments (basic, intensive and high intensive technology) as the main plots, and spring wheat cultivars (Zelata, Lubova, Liza and Ester) as the sub-main plots. The highest grain yield (10.8 t ha^-1), harvest index (42.9%), gluten content (39.45%) and gluten index (71.17%) observed for spring wheat cultivar Lubova with the moderate application of farming inputs as an intensive cultivation technology. Highest protein content (18.02%) was attained for both intensive and high intensive cultivation technology with the cultivar Lubova, and the highest 1,000 grains weight (46.32 g) was recorded by cultivar Lubova in basic cultivation technology. Applying moderate amount of inputs as an intensive cultivation technology resulted in highest wheat yield and net income.
