The natural diet of free-ranging horses is grass, which is typically high in fiber and calorically dilute, however diets for high performance domestic horses are often low in fiber and calorically dense. The aim of the study was to determine the motivation of horses for hay when fed a low roughage diet. Their motivation could be used to determine if low roughage diets compromise the welfare of ...
Past positive experiences can increase herbivores' motivation to eat low-quality foods. However, this is not always translated into a higher preference for low-quality foods in choice tests among foods of higher nutritional quality. Foraging behavior is also affected by properties of the feeding context because the quality and abundance of foods in nature change in time and space. We hypothesiz...
Twenty Naieni breed replacement ewe lambs were used to determine the substitution effects of treated wheat straw with exogenous fiber-degrading enzymes for alfalfa hay on wool characteristics. Five treatment diets were included: 1) control (100% alfalfa hay without wheat straw), 2) 10% enzyme treated wheat straw replaced for alfalfa hay, 3) 20% enzyme treated wheat straw replaced for alfalfa ha...
We evaluated the effect of wet corn gluten feed and a novel product containing raw soybean hulls and corn steep liquor on performance in lactating dairy cows. Forty-six multiparous Holstein cows were used in a randomized incomplete block design. Cows were housed in tie stalls for the first 13 weeks of lactation and moved to group pens for the remainder of the study. Cows were blocked by calving...
In an Alpine environment, diets based on local forage resources are needed to maintain the link with the territory and confer special characteristics to typical cheeses. Harvesting at a late stage of maturity, high mechanical losses, and frequent rainfall often make the hay that is harvested of a poor quality. The aim of this study was to evaluate the effects of 2 different conservation methods...
BACKGROUND To date, no genome-wide association study (GWAS) has considered the combined phenotype of asthma with hay fever. Previous analyses of family data from the Tasmanian Longitudinal Health Study provide evidence that this phenotype has a stronger genetic cause than asthma without hay fever. OBJECTIVE We sought to perform a GWAS of asthma with hay fever to identify variants associated w...
STORAGE AND FEEDING Each year more than 60 million acres of forage crops are harvested for hay in the United States. Annual production from this acreage is over 150 million tons of hay valued at more than 12 billion dollars. Hay is the most widely grown mechanically-harvested agronomic crop in the United States. As a source of nutrition for livestock, hay offers numerous advantages. It can be m...
Supplementation of forage-fed livestock has been studied for decades; however, as by-products become available research is needed to determine optimal feeding rates for increased efficiency. Five ruminally and duodenally cannulated beef steers (446 +/- 42 kg of initial BW) were used in a 5 x 5 Latin square to evaluate effects of increasing level of supplemental corn distillers dried grains with...
The present qualitative study emanates from a phenomenological perspective and has the purpose of creating an understanding for what a so-called “hay sack” is as well as understanding the experiences of a hay sack. In this context a hay sack refers to a person with low physical activity. Eight hay sacks between 36-58 years of age were interviewed about their experiences. Karlsson’s (1995) EPP-m...
Four rations that differed in their crude protein and essential amino-acid content were compiled. Digestibility of the crude protein and essential amino-acid contents were determined biologically in a feeding trial using 4 Anglo-Arab stallions. Their respective daily diets were: Diet 1:2 kg cubes, 5 kg tef hay (Eragrostis tef); Diet 2:2 kg cubes, 5 kg lucerne hay (Medicago sativa); Diet 3:2 kg ...
