Book Description
Published research suggests that it might be beneficial to increase the amount of rumen undegradable protein (RUP) that passes out of the rumen, through manipulation of rumen fermentation to establish a lower rumen pH. To test this hypothesis, a study was conducted in which three ruminally cannulated Holstein cows, 722 kg ; 25.6 kg fed three different diets (treatments) were used in a Latin square design experiment to determine effects of increasing levels of dietary concentrate on some rumen parameters and ruminal crude protein (CP) degradability. The in situ method was used to determine the ruminal protein degradability of sunflower oilcake, cottonseed oilcake and roasted soya. The three treatments differed in roughage:concentrate ratio, being 60:40 (Treatment UP 60), 45:55 (Treatment UP 45) and 30:70 (Treatment UP 30). Intake of dry matter (DM) (kg/day) did not differ between treatments. The mean rumen pH in cows receiving the three experimental diets differed and was 6.00, 6.27 and 6.44 for treatments UP 30, UP 45 and UP 60 respectively. The time (hours) below pH 5.8, which is considered to be the pH where fibre degradation is substantially negatively affected, was approximately 2.5 hours, but only on treatment UP 30. Mean rumen ammonia nitrogen (N) and total volatile fatty acid (VFA) concentrations did not differ among cows receiving different treatments but, cows fed treatment UP 30 had a lower ruminal acetic acid:propionic acid (A:P) ratio compared to the other treatments. There were no differences in ruminal CP degradation within the three feedstuffs when incubated in cows fed diets with different roughage:concentrate ratios. Results suggest that roughage:concentrate ratios ranging from 60:40 to 30:70, which resulted in mean pH values ranging from 6.4 to 6.0, did not affect ruminal CP degradation of sunflower oilcake, cottonseed oilcake and roasted soya.

Gut efficiency; the key ingredient in ruminant production
Author: Sylvie Andrieu
Publisher: BRILL
ISBN: 9086866409
Category : Technology & Engineering
Languages : en
Pages : 111
Book Description
Globally, dairy and beef production has become an extremely competitive industry. While the world milk production is predicted to grow significantly by 2020 with the emergence of new consumers in developing countries, milk and meat production in the more establish markets now has to fulfil new societal needs beside the simple product supply: animal health, food safety, and production environmental impact are some of them. At the same time, the recent extreme increase in feed costs emphasizes again the key role of rumen and gut efficiency management in production economics. All these new thematic topics are central to the proper management of ruminant digestive process. Producers must endeavour to seek new technologies to improve production efficiency, animal health and production costs while keeping in mind the environmental impact these changes make. ‘Gut efficiency; the key ingredient in ruminant production’ brings together some of the world’s leading authorities in the field of ruminant nutrition and production. It considers the importance of digestive health in performance achievement together with novel strategies to manage it. It is aimed at nutritionists, veterinarians and animal producers as well as students and researchers studying animal and applied biological sciences.
