Fodder beans (Vicia faba minor ) and peas (Pisum sativum) in dairy cows feed rations

Abstract

Holstein-Friesian Black-and-White cows with analogous characteristics were selected and randomly allocated into 4 groups (control and trials), 5 animals each. In vitro digestibility tests of the legumes (peas and fodder beans) are high from 80.50 % to 84.20 %. The feed ration digestibility study results show, that on average higher dry matter digestibility was in the 2 nd group-69.42 %, in which the feed ration peas "Bruno" was included, and the 1 st trial group-69.29 %, in which the ration peas+beans was included. The highest protein digestibility is also presented by the 2 nd trial group of cows-65.97 % and the 1 st trial group of cows-65.82 %. The milk yield decreases for the experimental groups (1 st and 2 nd) were smaller-0.8 kg, 1.3 kg, respectively, compared with the initial stage of the experiment (p < 0.05). The changes in productivity are mainly associated with the cows' physiological processes during their lactation and pregnancy cycle.In contrast, group 4 (control) showed a significant decrease in the average daily energy corrected milk yield (4.9 kg), compared with the initial stage of the trial. Compared with the control group, none of the dietary interventions showed significant (p>0.05) deviations.

Garden Peas Production Variation in Relation to Some Biostimulating Substances

“…The pea is a nutritionally important legume for human food and animal feed (Ashiev et al, 2021;Hacisalihoglu et al, 2021;Kumari & Deka, 2021). Peas have been studied in relation to food benefits (Dahl et al, 2012;Kumari & Deka, 2021;Abebe, 2022), fodder (Trūpa et al, 2018;Abebe, 2022), structure of agricultural crops (Gollner et al, 2019;Powers & Thavarajah, 2019). Some studies have evaluated peas in conditions of intercropping, or in relation to some nutritional elements AgroLife Scientific Journal -Volume 12, Number 2, 2023ISSN 2285ISSN CD-ROM 2285-5726;ISSN ONLINE 2286-0126;ISSN-L 2285-5718 (nitrogen fixation, phosphorus regime, etc.…”

Development of equipment for producing feed mixtures with nanoparticles of scarce micronutrients

“…Particles of components with different sizes, different densities, etc., mix longer, all other things being equal. Mixing takes longer, if any components are in the mix in small quantities [11][12][13]. As parameters for evaluating the DOI:10.22616/ERDev.2020.19.TF469 effectiveness of mixing processes, we should use the specific energy consumption for the process and the quality indicators of the mixture.…”
