Abstract
Abstract. The aim of this study is to determine the effect produced by selected pea cultivars with different anti-nutritional content on dairy cows’ metabolism. In the current ninety-day present, 32 dairy cows were divided into four groups (Z, G, GU and C). Three experimental groups (Z, G and GU) were fed a production mixture consisting of 25% pea seeds and the following: (Z – Zekon cultivar with low anti-nutritional content; G - Gotik cultivar with high antinutritional content; and GU – Gotik cultivar whose anti-nutritional content was reduced technologically). The control group was fed the production mixture with a higher proportion of extracted soybean meal and grain meal. Feeding rations were balanced to have an analogical composition of crude protein and energy. Feeding the pea supplement did not affect energy metabolism of the dairy cows. As for nitrogen metabolism, group Z showed higher concentrations of ammonia in rumen fluid and urea in blood compared to groups GU and C. No animal from the experimental groups showed reduced intake of feed. An insignificantly lower performance was noted (daily milk yield, protein production and lactose production) in group G. Overall, better results were observed in group Z. On the basis of the current study, peas can be used as an alternative source of proteins and energy in the diet of dairy cattle.
Highlights
A steadily growing volume of milk production on dairy cattle farms has increased demands of dairy cows in terms of their nutrient intake
The aim of the study was to evaluate the metabolism and performance of dairy cows that were fed production-feeding mixtures consisting of selected cultivars of peas with different anti-nutritional content, as well as peas treated by the above-mentioned method
Thirty two dairy cows were selected for the experiment, divided on the principle of analogous tetrads according to breed, age and efficiency to the three experimental groups (Z, G, GU) and one control group (C)
Summary
A steadily growing volume of milk production on dairy cattle farms has increased demands of dairy cows in terms of their nutrient intake. Besides sufficient content of energy in feeding ration, high productivity of dairy cows is based on sufficient intake of crude protein with high content of quality protein. These nutrients have been supplied by extracted soybean meal. The following anti-nutritional substances are contained in peas (listed in order of significance): trypsin inhibitors, lectins (phytohemaglutinins), flatulent oligosaccharides, gallic acid and other substances from the phenolic group or substances with phytoestrogenic effects. The aim of the study was to evaluate the metabolism and performance of dairy cows that were fed production-feeding mixtures consisting of selected cultivars of peas with different anti-nutritional content, as well as peas treated by the above-mentioned method. The cows were monitored during 90 days of their lactation period
