Efecto de la suplementación con ensilaje de naranja sobre la composición de la leche bovina

Contextualization: In livestock production, food supplementation is carried out with commercial feed that increases production costs and thus affects the profit margins of livestock companies.

Research gap: Orange silage is seen as a nutritional and economic alternative for livestock companies in search of sustainability under the following questions: What is the effect of orange silage on the productivity and quality of bovine milk? Is it possible to reduce the Feeding costs by including this silage and reducing the feed without affecting the productive parameters in milk cattle?

Purpose: The main objective of this study was to evaluate the effect of orange silage (EN) supply on bovine milk composition at the Villa Marina Experimental Farm of the University of Pamplona.

Methodology: A randomized complete block design was used with 12 animals whose genetics are influenced by the Gyr, Holstein, Jersey and Swedish Red breed, distributed in a treatment with the substitution of 20% of commercial balanced food (T1) and a control (T2). The EN was elaborated with fruits produced on the farm with 30 days of fermentation. A period of 10 days of accustoming was carried out. The milk composition (fat, protein, non-fat solids (SNG), minerals and lactose) were measured every seven days for 90 days. The data obtained were subjected to an analysis of variance and correlation.

Results and conclusions: The inclusion of EN generated a higher (P<0,05) fat content (4,36%) in the cow’s milk, compared to the control treatment (3,75%). There was no effect of treatments on the remainder milk components evaluated. The daily production of milk was not affected (P>0,05) by treatments. The replacement of commercial balanced food by 20% with EN improves the milk fat content and decreases the costs of feeding, compared to conventional management, becoming a sustainable feeding alternative in crossbreed lactating cows.
