Effects of diets with increasing levels of golden flaxseed on carcass characteristics, meat quality and lipid traits of growing rabbits
The aim of this study was to determine the effects of three levels (0, 8, or 16%) of the golden variety of flaxseed (GFS; Linum usitatissimum L.), included in isonitrogenous and isocaloric diets, on the carcass characteristics, meat composition and fatty acid profile of rabbit meat and perirenal fat. The trial was carried out on 30 weaned crossbred rabbits aged 9 weeks, weighing on average 2074 g. The animals were divided equally into three groups of 10 (five male and five female rabbits each) and kept separate in individual cages. At the end of the experiment, which lasted 5 weeks, there were no significant differences between the groups in the carcass yield or the proportions of various carcass parts and edible organs. Although the chemical composition of the meat was not signiïŹcantly affected by the dietary treatment, the saturated fatty acid and monounsaturated fatty acid proportion in the longissimus dorsi muscle (-22% and -24%, respectively) and perirenal fat (-34% and –29%, respectively) decreased and the polyunsaturated fatty acid (PUFA) increased (+36% in the muscle and 43% in the fat, respectively) with increased GFS inclusion. GFS dietary supplementation has shown to be effective in improving the n-3 PUFAproportion (76% in the muscle and 77% in the fat, respectively), decreasing the n-6/n-3 ratio and reducing the saturation, atherogenic and thrombogenic indexes of the meat, with consequent benefits on the nutritional quality of rabbit meat for consumers
Effects of diets with increasing levels of Spirulina Platensis on carcass characteristics, meat quality and fatty acid composition of growing rabbits.
The effect of a diet supplement containing S-acetyl-glutathione (SAG) and other antioxidant natural ingredients on glutathione peroxidase in healthy dogs: a pilot study
Effects of replacing palm oil with maze oil and Curcuma Longa supplementation on the performances, carcass characteristics, meat quality and fatty acid profile of the perirenal fat and muscle of growing rabbits.
Appraisal of ingestion and digestibility in growing rabbits using near infrared reflectance spectroscopy (NIRS) of feeds and faeces
The aim of this work was to examine whether faecal profiling using NIRS could be profitable for promote the Best Available Techniques (BAT) in the rational feeding of rabbits. A set of 51 feed samples, taken from 12 experimental diets, and of 66 dried grouped faeces samples, belonging to four nutrition experiments, with 130 ad libitum registered feed intakes (CV=25%), were submitted to a UV-Vis-NIRS scan (350-2500 nm) in order to calibrate the chemical composition and nutritional parameters, the ingestion aptitude and digestibility. A chemometric system has made it possible to contemporary use the spectrum of the input diet concatenated together with the spectra of the related output pool of the dried faeces. The daily measured feed intake, in absolute or in relative terms as ingestion per unit of metabolic weight, obtained a good resolution for the spectra of the feeds (R2 cv=0.80 and 0.75, respectively), for the faeces (0.81 and 0.80) and for the joint evaluation of the concatenated spectra (0.87 and 0.81). The intake was positively correlated to the mineral, insoluble ash, protein, gross energy, crude fiber and acid detergent fiber (ADF) content in the feeds, and negatively correlated to the N-free extract, lignocellulose and all the digestibility coefficients, except crude fiber. Very significant improvements, on average equal to 0.20 R2 points, were also provided to the digestibility coefficients when using the concatenated method; in decreasing order: neutral detergent fiber (R2 cv=0.00, 0.18 and 0.50 for the feeds, faeces and concatenated, respectively), ADF (0.00, 0.45 and 0.62), ether extract (0.53, 0.52 and 0.86), crude protein (0.53; 0.53 and 0.75), and gross energy (0.61; 0.74 and 0.83). The results corroborate previous knowledge and show the possibility of using NIRS faecal profiling in rabbit nutrition, which together with the NIRS of the feeds, could contribute to nitrogen monitoring
Leaner, Healthier, Happier Together—-A Family-Centred Approach to Weight Loss with the Overweight Dog and Her Caregivers
Obesity represents a one of the most significant healthcare issues facing human and companion animal populations worldwide. A complex relationship commonly exists between owners and their companion animal, particularly around feeding behaviour. Obese companion animals commonly live alongside caregivers who are also struggling with their own body weight. This case report highlights the importance of a family-centred approach to canine obesity as a way to engage with the petâs caregivers to help maximize their compliance towards the successful implementation of a tailored weight loss programme. Lara, an overweight dog weighing 35 kilos with a body condition score (BCS) of 7â7.5/9, was referred for a nutritional assessment. A comprehensive, pro-active and multidisciplinary protocol, tailored towards a family-centred approach, was established. After a 16-week programme, Lara reached the target body weight. The caregiversâ compliance was assessed as being excellent; they also reassessed their individual lifestyle and were able to increase awareness towards their own nutritional issues and body weight perception, resulting in weight loss in all caregivers. Laraâs case report represents how a family-centred approach can lead to successful patient weight loss and to a modification in the caregiversâ way of thinking about nutrition and their own lifestyle, with the final goal of living a healthier and longer life together
