Registration of new hop variety (Humulus lupulus L.), with denomination Styrian gold, reg. no. HUL029

The hop breeding program is the most extensive breeding program in Slovenia, the own varieties are covering 95% of hop fields. The application of knowledge directly into the praxis is the registration of new variety while 6 perspective breeding lines are under official field trials. New variety is protected patent.

The effect of two hop varities (Humulus lupulus L.) on in vitro gas and volatile fatty acid production in dairy cows

Hop growing is one of the main branches in Slovenian agriculture. With ban of antibiotics in animal nutrition in EU, the economics of animal production is reduced and for this reason effective substitutes are intensively researched. Because of the needs for supplying safe food to consumers and saving the sustainable Slovenian hop growing, we did the experiment on growing chickens with the intention to research the antioxidative effect of hops and their influence on animal health, performance and meat quality. Broiler chickens Ross 308 (N=84) were included in the nutritional study. Animals were divided into three groups. The diets were supplemented with linseed oil (7.5 %), which is high in n-3 PUFA. The experimental diets where as follows: 1. Diet - no additives (CONT), 2. Diet - HOPS_0.9: CONT + 0.9 g hops/kg of diet and 3. Diet - HOPS_3.6: CONT + 3.6 g hops/kg of diet. Animal performance and health, feed consumption, oxidative stress and meat quality and oxidative stability of chicken meat were evaluated. Oxidative stress in vivo was studied by measuring the DNA damage of blood cells, measuring malondialdehyde (MDA) in plasma, and analysing the antioxidant capacity of the lipid (ACL) and water (ACW)-soluble compounds. The hop supplementation did not influence chicken performance. The supplement of 3.6 g hop/kg induces MDA formation and decreases DNA fragmentation. ACL was significantly reduced in the group supplemented with 3.6 g hops/kg in comparison to the group CONT. Further studies are needed to confirm the results of the present study.
