- ItemFactors affecting the purchasing of rabbit meat : a study of ethnic groups in the Western Cape(South African Association for Family Ecology and Consumer Sciences, 2004) Hoffman, L. C.; Nkhabutlane, Pulane; Schutte, De W.; Vosloo, CharlynDie bemarking van konynvleis in ander lande het ’n verskuiwing ondergaan, van die verkoop van heel konynkarkasse tot die later ontwikkeling van die verkoop van konynvleis in porsies as ’n geriefsverpakking. Ander bemarkingsvraagstukke met betrekking tot konynvleis, byvoorbeeld of daar ’n mark daarvoor is, is nie ondersoek nie. In hierdie studie is die bemarkingspotensiaal van konynvleis ondersoek. Die beskrywende opnamemetode, wat gebruik maak van ’n gestruktureerde vraelys, is gebruik en toegepas op 304 respondente. Die gemiddelde waardes van faktore wat die bemarking en aankoop van konynvleis beïnvloed, is bereken. Dit was bepaal dat die mark vir konynvleis nog baie beperk is. Slegs 43% van die respondente wat wel konynvleis verbruikers is, het aangedui dat hulle een of twee keer per maand konynvleis sal wil eet, waarvan 29 swart, agt wit en 23 bruin respondente was. Die voorgenome frekwensie van inname van die res van die verbruikers van konynvleis was een of twee keer per jaar. Die resultate dui daarop dat respondente, wat verbruikers van konynvleis is, dit sou verkies om konynvleis in porsies (53%), eerder as die hele karkas te koop. Indien vars verkoop, sal dié porsies die bemarkbaarste wees. Varsheid is deur al die respondente, ongeag etniese groep, as die belangrikste kwalitatiewe eienskap van konynvleis beskou. Die meeste respondente het aangedui dat hulle die agter- en voorbeen, en borsgedeeltes as porsies sal verkies, met die agterbeen as die mees gewilde gedeelte en die borsgedeelte as die minste gewild. Die verskille wat waargeneem is in die opinies met betrekking tot die bemarking van heel karkasse, het aangedui dat die swart respondente die kop saam met die karkas sou wou koop. Die hoofrede vir dié voorkeur, is dat hulle wil seker maak dat die karkas wat aan hulle verkoop word, inderdaad dié van ’n konyn is, en nie van ’n kat nie.
- ItemThe quality attributes of South African rabbit meat and consumer attitudes towards it(Stellenbosch : Stellenbosch University, 2004-03) Nkhabutlane, Pulane; Hoffman, Louwrens C.; Vosloo, M. C.; Schutte, De W.; Stellenbosch University. Faculty of Science. Dept. of Consumer Science.ENGLISH ABSTRACT: Meat processing industries in South Africa are faced with the challenge to produce a variety of white meats. This is due to the fact that consumers tend to consume less red meat and more chicken and pork that are perceived to be healthier due to the negative publicity surrounding red meat and health. The nutritional emphasis is on leaner carcasses and an increase in the consumption of polyunsaturated fatty acids while reducing the ratio of n-6:n-3 polyunsaturated fats in the diet. Another way in which this can be achieved is through introducing rabbit meat which has low fat, low cholesterol content and high protein content, while displaying a positive fatty acid profile. Carcass quality and meat quality in rabbits may to a large extent be affected by age of slaughter and type of breed. This study had a dual purpose. Firstly it aimed at quantifying the effects of breed and age on parameters pertaining to carcass quality and meat quality of commercial rabbits, namely California breed and hybrid (California x Dutch red). Secondly, to determine the differences between ethnic groups on their perceptions towards rabbit meat, thereby providing information on its marketing potential. To accomplish the first objective 50 rabbits from the two breeds were housed in individual cages, weighed on weekly basis and fed ad libitum. The rabbits were slaughtered at 9, 11, 13, 15 and 17 weeks of age (n=5 from each breed). For the second objective the perceptions of three ethnic groups on factors affecting consumers' choice of rabbit meat were determined through a structured questionnaire. The questionnaire was tested for validity beforehand. There was no significant difference between the two breeds regarding body weight, feed intake, carcass weight and drip loss. The California breed had a higher dressing percentage (53.7%) and meat yield (29.2%) compared to the hybrid (52.5% and 27.5% respectively). Age treatments showed a highly significant difference on all parameters investigated. Increasing the age proportionately increased the amount of fat, while the moisture content decreased. The California breed exhibited higher percentages of fat compared to the hybrid at all ages of treatment. California breed contained more phosphorus, magnesium and zinc as opposed to the hybrid, the only exception being copper, where the hybrid had higher concentrations. The total fatty acid (169.2 mg/100 g) of the California breed was higher than that of the hybrid (133.5 mg/100 g). As a result there were more saturated fatty acids (55.4 mg/100 g) and monounsaturated fatty acids (62.3 mg/100 g) in the California breed than in the hybrid (44.2 and 45.6 mg/100 g respectively). Both breeds had 67% unsaturated fatty acids. Although there was no significant difference between the P:S ratio of the two rabbit breeds, the values obtained were higher (+0.9) than the value of 0.7. This is an indication that the rabbit meat contains a P:S ratio that could be considered very desirable. The n-6:n-3 ratio for both breeds were high (11.6 for California and 12.7 for hybrid). The cholesterol and amino acid profile of the two breeds were not affected by the type of breed. The consumer survey indicated that 52% (n=158) of respondents had never eaten rabbit meat before due to reasons such as scarcity, lack of knowledge about the meat, associating rabbits with pets and cultural constraints. Nevertheless, 57% of these people were optimistic about eating rabbit meat. In addition, having eaten rabbit meat before seemed to contribute positively towards acceptance of rabbit meat. Generally, respondents preferred purchasing rabbit meat in portions as opposed to live or whole carcasses. Their decision to purchase rabbit meat was firstly driven by price, thereafter freshness, leanness and tenderness of meat. The respondents expect to buy rabbit meat at a price lower than that of chicken. Rabbit meat contained low sodium and high proportion polyunsaturated fatty acids-some of the most important food attributes required to maintain and improve health. However, most of the respondents in this study were not familiar with the positive attributes of rabbit meat and need to be taught the benefits of this product.
