Dietary inclusion of fermented ginger straw effect on the growth performance, gastrointestinal tract development and caecal fermentation of fattening rabbits
This experiment was conducted to evaluate the effects of dietary inclusion of fermented ginger straw on the growth performance, gastrointestinal tract development and caecal fermentation of fattening rabbits. A total of 160 45-d-old Laiwu black rabbits were randomly divided into 4 groups and fed 0% (Control), 5, 10 or 15% fermented ginger straw in their diet as a replacement for peanut straw powder. The trial lasted for 7 d of adaptation and 43 d for testing. Growth performance was recorded from 52 to 95 d of age (n=5 per treatment with 30 rabbits, 3 males and 3 females per replicate), TTAD of nutrients from 91 to 95 d of age, and gastrointestinal tract development, caecum fermentation and carcass traits were determined at 95 d of age (n=5 per treatment with 10 rabbits, 1 males and 1 females in per replicate).The results showed that the average daily gain and final body weight in the experimental groups (5, 10 and 15% fermented ginger straw) were higher than in the control group (P<0.05). However, the average daily feed intake in the 15% group was higher than in the other groups, while the total tract apparent digestibility of crude protein, ether extract, neutral detergent fibre and acid detergent fibre were lower than in the control group (P<0.05), and the relative weights of the stomach, small intestine and caecum content in the 15% substitution group were higher than those in the control group (P<0.05). In addition, the thickness of the muscle layer in the 15% substitution group was higher than that in the other groups (P<0.05). Moreover, pH and total volatile fatty acids concentration in the caecal content were similar among the 4 groups (P>0.05). The current work shows that fermented ginger straw could be used as roughage material in fattening rabbit production up to a dietary dose of 10%.
期刊介绍:
World Rabbit Science is the official journal of the World Rabbit Science Association (WRSA). One of the main objectives of the WRSA is to encourage communication and collaboration among individuals and organisations associated with rabbit production and rabbit science in general. Subject areas include breeding, genetics, production, management, environment, health, nutrition, physiology, reproduction, behaviour, welfare, immunology, molecular biology, metabolism, processing and products.
World Rabbit Science is the only international peer-reviewed journal included in the ISI Thomson list dedicated to publish original research in the field of rabbit science. Papers or reviews of the literature submitted to World Rabbit Science must not have been published previously in an international refereed scientific journal. Previous presentations at a scientific meeting, field day reports or similar documents can be published in World Rabbit Science, but they will be also subjected to the peer-review process.
World Rabbit Science will publish papers of international relevance including original research articles, descriptions of novel techniques, contemporaryreviews and meta-analyses. Short communications will only accepted in special cases where, in the Editor''s judgement, the contents are exceptionally exciting, novel or timely. Proceedings of rabbit scientific meetings and conference reports will be considered for special issues.
World Rabbit Science is published in English four times a year in a single volume. Authors may publish in World Rabbit Science regardless of the membership in the World Rabbit Science Association, even if joining the WRSA is encouraged. Views expressed in papers published in World Rabbit Science represent the opinion of the author(s) and do not necessarily reflect the official policy of the WRSA or the Editor-in-Chief.
