Effects of replacing rapeseed cake with linseed cake in a corn-grass silage-based diet for milking cows
Journal Title: Animal Science Papers and Reports - Year 2016, Vol 34, Issue 2
Abstract
The aim of this study was to evaluate the substitution of rapeseed cake by an equivalent amount of linseed cake in the diets of dairy cows, and the effects of such equivalent substitution on the proportion of feed consumed, milk yield and chemical composition, fatty acid structural composition in their milk fat, and the metabolic profile of the cows’ metabolism. The studies were conducted on 16 Polish Holstein-Friesian cows, divided into 2 groups [n= 8] using the analogue method. Cows from the control group received an addition of rapeseed cake, while animals from the experimental group received linseed cake as a by-product of “cold” oil extraction. The cows were maintained in a free-stall system in a separated compartment fitted with the Calan-gate system and fed according to TMR systems. Following 70 days there were no significant differences in the daily milk fat, protein, lactose, and yield between the control vs. experimental groups. Additionally, the biochemical parameters in the blood serum of cows did not show negative effects of either diet on the animals’ health condition. Rapeseed and linseed cake have similar feeding value. The slight improvement in the fatty acid structure in the milk fat of cows receiving linseed cake is of no greater practical value. Thus, in European conditions rapeseed cake should be preferred, as its availability is wider and its price is lower.
