Comparative assessment of the nutritional value of feed from rare silage crops

Relevance . The article is devoted to the study of nutritional and energy value feed from perennial rare silage crops — goatʼs rue eastern pierced leaf sylphia, ways improve quality their using low-cost methods conservation. Methods research was carried out in 2019–2021 at Gubino agricultural polygon VNIIMZ (Tver region). Highly productive were studied: goat, freshly mown plus meadow fescue (60:40%); pronzennolistnaya silfia slightly dried; silfia; otava goat corn (control). area experiment 6.1 hectares, placement options randomized, three tiers, repetition three-fold, use twoaxis. Results preparation high-quality perennial, uncommon requires special technological methods: choice vegetation phase which culture has optimal ratio nutrients, carbohydrate additives, wilting mass. In course research, samples all varieties grass mixtures analyzed a comparative aspect. It found that total content organic acids high (1.68– 3.22%). Lactic acid fermentation prevailed variants, ensured production 1st class. largest share lactic (more than 80%) falls on corn. concentration exchange highest (11.8 MJ/kg), mixture (11.1 (10.9 MJ/kg) joint with (10.8 dry matter (SV), respectively (the significance differences p < 0.05).
