Effect of nutritional status of kits on carcass traits and meat quality (preliminary results)
No full textThe aim of the experiment was to study the effect of nutritional supply during foetal, suckling and growing periods on carcass traits and meat quality of rabbits. New-born rabbits (n=224) were divided into three groups according to their birth weight (low/L/: 35-50 g, medium/M/: 58-62 g, high/H/: 70- 88 g). Half of the litters were nursed by one doe (O), while the other half by two does (T). After weaning at 3 weeks, from the age of 4 weeks half of the rabbits were fed ad libitum, while the other half was reared on a restricted feeding regime corresponding to 85-90% of the ad libitum feed intake level. Rabbits were slaughtered at 11 weeks of age. Body weight at slaughter of L rabbits was 124 g lower than M and 255 g lower than H rabbits (P<0.05). L group had the highest (58.0%) while M rabbits the lowest dressing out percentage (57.3%) (P<0.05). Ratio of hind part was significantly (P<0.05) higher in H group (39.0%) than in L group (38.1%). Ratio of perirenal fat was the highest in L rabbits (2.10%) and the lowest in H group (1.64%) (P<0.05). Value of WHC was 1.8% lower (P<0.05) in H rabbits compared to L and M animals. Slaughter weight of T rabbits was 198 g higher (P<0.001) than that of group O. Dressing out percentage was 0.7% (P=0.002) lower in T rabbits. In group T the cooking loss of m. Longissimus dorsi was 1.6% lower (P=0.003) than in group O. In consequence of feed restriction the slaughter weight and dressing out percentage decreased by 141 g (P<0.001) and 0.8% (P=0.001), respectively. Feeding regime influenced all the meat quality parameters except the b* value of meat colour. Rabbits in restricted group had 0.08 (P<0.001) lower pH, while 1.1 (P<0.001) higher L* and 0.7 (P=0.008) lower a* values of m. Longissimus dorsi. The cooking loss of m. Longissimus dorsi of restricted rabbits was 1.2% higher (P=0.03). Birth weight x number of nursing does x feeding interaction had significant (P<0.05) influence on the lipid content of m. Longissimus dorsi: the highest lipid content was found in MOA rabbits (2.30%) while the lowest in HOA (1.18%) and in LOR (1.21%) groups. Birth weight x number of nursing does interaction was significant on the proportion of m. Longissimus dorsi to reference carcass weight (P=0.03) and on meat to bone ratio (P=0.02). Highest ratio of m. Longissimus dorsi was found in LO and MO groups (11.9%), while LT rabbits showed the lowest value (11.4%). Meat to bone ratio was the highest in HT rabbits; it differed significantly (P<0.05) from other groups except MT. These results show that the nutrient supply during foetal and suckling ages has a long term effect which could be important in terms of carcass traits and meat quality as well
Effect of nutritional status of rabbit kits on their productive performance, carcass and meat quality traits
No full textThe effect of nutrient supply at foetal, suckling and growing ages on productive, carcass and meat quality traits of rabbits was studied. New-born rabbits were divided into three groups according to their birth weight (low/L/: 35–50 g, medium/M/: 58–62 g and high/H/: 70–88 g). Half of the litters were nursed by one doe (O) and the other half by two does (T). The kits were weaned at 3 weeks. From the age of 4 weeks, half of the rabbits were fed ad libitum (A), or on a restricted regime (R) (85–90% of the ad libitum feed intake level). Rabbits were slaughtered at 11 weeks of age. Difference in average feed intake between groups L and H, groups O and T and between R and A was 11.2%, 7.8% and 11.7%, respectively; in all cases, the latter groups had the highest intakes. Body weight gain between 3 and 11 weeks was significantly affected by birth weight and feeding regime. Body weight at slaughter of L rabbits was 124 g lower than that of M rabbits and 255 g lower than that of H rabbits (P < 0.05). Group L had the highest dressing out percentage (58.0%), whereas M rabbits had the lowest dressing out percentage (57.3%) (P < 0.05). Ratio of hind part of the reference carcass was higher in group H (39.0%) than in group L (38.1%) (P < 0.05). Percentage of perirenal fat was the highest in L rabbits (2.10%) and the lowest in group H (1.64%) (P < 0.05). Slaughter weight of T rabbits was 198 g higher (P < 0.001) than that of group O. Chilled carcass weight and dressing out percentage were 16 g (P = 0.006) and 0.7% (P = 0.002) lower, respectively, in T rabbits. In consequence of feed restriction slaughter weight, chilled carcass weight and dressing out percentage decreased by 141 g (P < 0.001), 22 g (P < 0.001) and 0.8% (P = 0.001), respectively, while the ratio of liver and kidneys to liveweight increased by 0.57% (P < 0.001) and 0.05% (P < 0.001). Cooking loss of musculus longissimus dorsi (MLD) was 1.8% lower (P < 0.05) in H rabbits compared with L and M animals. Cooking loss was 1.6% lower (P = 0.003) in group T than in group O. Due to the restriction, slaughter weight and dressing out percentage decreased by 141 g (P < 0.001) and 0.8% (P = 0.001), respectively. Feeding regime influenced all meat quality parameters except the b* value of meat colour. Rabbits in R group had 0.08 (P < 0.001) lower pH, while 1.1 (P < 0.001) higher L* and 0.7 (P = 0.008) lower a* values resulted lighter colour of MLD. The cooking loss of MLD of R rabbits was 1.2% higher (P = 0.028). Results show that the foetal and suckling nutrient supply exert a long-term effect, affecting also carcass traits and meat quality

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Effect of different housing on productive traits and on some behaviour patterns of growing rabbits
No full textSimulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
EFFECT OF DIFFERENT HOUSING ONPRODUCTIVE TRAITS AND ON SOMEBEHAVIOUR PATTERNS OF GROWINGRABBITS. PRELIMINARY RESULTS
No full textTwo-hundred-twenty-eight 5-week-old Pannon
White rabbits were housed in cages (2 rabbits/
cage, 0.12 m2) or in pens (13 rabbits/pen, 0.83
m2) with the same stocking density. Half of the
cages and pens had wire net floor while the other
half had plastic net. In every second cage and
pen wooden gnawing stick was fixed onto the
wall. Every second week a 24-hour video
recording was done. At 11 weeks of age ear
lesions were checked. Body weight of rabbits in cages was significantly higher between 7 and
11 weeks of age. Floor type had no influence on
weight gain and body weight. Rabbits in cages/
pens with gnawing stick were significantly
heavier at 11 weeks of age. Mortality was
independent of all treatments. Gnawing stick
consumption was significantly higher in pens.
Ear lesions were more frequent in rabbits housed
in pens or on plastic net, however, significant
difference was found only between rabbits with
or without wooden stick, with higher ear lesions
on rabbits reared without wooden stick
Intern experience at CH���M Hill, Inc.: an internship report
No full textIncludes author's vita"Submitted to the College of Engineering of Texas A&M University in partial
fulfillment of the requirement for the degree of Doctor of Engineering."Includes bibliographical referencesA review of the author's internship experience with CH���M HILL, Inc.
during the period September 1975 through May 1976 is presented. During this nine month
internship the author worked as an Engineer II in the Industrial Processes discipline of this
large consulting engineering firm... The author's prime responsibility was as one of three
lead design engineers on the design of a large wastewater treatment facility for a pulp mill
in Hoquiam, Washington owned by ITT Rayonier Inc. The work generally consisted of the design
of individual treatment units and associated piping and pumping. The purpose of the project
was to provide wastewater treatment capabilities that would satisfy the effluent limitations
(standards) imposed upon the mill by the State of Washington Department of Ecology and the
U.S. Environmental Protection Agency. The author's assignment also entailed necessary
interaction with the project manager and other CH���M HILL design engineers and support staff
members, the client's representatives, and representatives of two other consulting engineering
firms working on the project. Thus, the internship position at CH���M HILL provided considerable
experience coordinating the author's work with the work of other engineers, guiding the design
and administrative efforts of a support staff, and interacting regularly with the client and
other consulting firms. This broad exposure to a variety of engineering and organizational
problems provided a valuable educational experience
