Comparison of the nutritional value and digestibility of classical oat and black oat
Gergelová, Anna ; Plachý, Vladimír (advisor) ; Dušan, Dušan (referee)
A review of literature thesis includes articles and publications dedicated to the topic of the digestive tract, the issue of measuring the digestibility of horse nutriens, characteristics and nutritional values of the yellow oat (Avena sativa), black oat (Avena strigosa) and hay.
The practical part is devoted to comparing the nutritional values and digestibility of yellow and black oats in the ration using yellow or black with oat hay
The experiment was conducted on six horses borrowed from the Academic riding club in Prague - Suchdol in February 2016. The preparatory period was 5 days, and sampling of faeces took place fifth morning after the morning feeding. Three pairs were created out of the six horses. The first pair formed gelding breed, Czech warmblood, who were housed in the inner box stable. The second pair formed a Haflinger gelding breed housed in an outdoor box. The third pair formed a Hucul gelding breed and welsh cob, housed in an outdoor box. One of the horses from an experimental pair was fed oat hulls and other horse was fed black varieties oats Raven. Rations was the same for both of the horses and both experimental animals also received the same amount of roughage.
Digestibility coefficient was found at the base of the marker method using indicator lignin. The chemical analysis of determination of dry matter and ash, crude fiber (CF), neutral - detergent fiber (NDF), acid - detergent fiber ADF and acid - detergent lignin (ADL), crude fat and calculated using nitrogen-free substances process colors (BNLV) and organic matter (OH) were performed.
Among the experimental pairs there was no statistically significant difference. Therefore, the hypothesis about differences in nutritional and dietetic value of oat and black oat was rejected.
