“…Breed effects were also found significant for ejaculate volume, individual motility, concentration and total number of spermatozoa per ejaculated. Hulit et al, (1994) and Cobos et al, (1995) found no significant differences among the reproductive performance of different breeds if the animal reached the same final weight. Many researchers observed the effect of genetic makeup on sexual hormones of different breeds of rabbits (Chiericato et al, 1985 andCazabon et al, 2000).…”

Two hundred and twenty weaned rabbits of New-Zealand White (NZW) as exotic breed and Baladi Black (BB) as a local breed were used in the present study. The study included two experiments, where rabbits in the first and second groups were housed in unconditioning and conditioning rabbitry, respectively. The first experiment (lasted for 35 days post weaning) was designed to evaluate growth performance of rabbits as affected by breed and conditioning of the rabbitry. The 2nd experiment was carried out to evaluate mature rabbit reproductive traits by using 30 male rabbits, 15 of each NZW and BB in each group, during pre-mature period. The experiment lasted 3 months and aimed to estimate some blood serum constitutes and body thermoregulation, as well as age and weight at first mating and some parameters indicated fertilizing ability of bucks. Results showed that, daily weight gain , feed intake, feed conversion and final body weight of rabbits were significantly (P≤0.05) better in BB and in conditioning rabbitry than those of NZW rabbits and in the control -unconditioning group, respectively. Dressing percentage, carcass weight and relative internal organs weight, as well as, blood pictures of growing rabbits were significantly (P≤0.05) higher in conditioning and BB than in unconditioning rabbitry and NZW rabbits, respectively. Conditioning rabbitry significantly (P≤0.05) improved values of each of total protein and its fractions, some enzymes indicated liver activity, some physiological aspects indicated physiological ability of body-thermoregulation. Also, conditioning rabbitry significantly (P≤0.05) improved net revenue and relative economic efficiency as compared to unconditioning group. Results of the second experiment indicated that, scrotal circumference, testicular index and mating activity, as well as, female and male sexual hormones were significantly (P ≤ 0.05) higher in BB and in conditioning rabbitry than NZW and unconditioning rabbitry, respectively. Baladi Black rabbits showed libido; physical semen quality; conception and kindling rates; litter size and bunny weight at birth and at weaning and pre-weaning mortality rates significantly (P ≤ 0.05) better than NZW rabbits, using natural mating or artificial insemination. Libido and physical semen quality of bucks, and fertility traits of does mated naturally or inseminated artificially were significantly (P ≤ 0.05) improved by conditioning the rabbitry, in each breed. Using air conditioning in rabbitries showed a significant improvement in the economic efficiency of rabbit production.

“…Silva et al (31) described that unsaturated fatty acids are related to the maintenance of human health since they raise serum levels of high-density lipoproteins (HDL) and reduce levels of low-density lipoproteins (LDL), parameters that are associated with cardiovascular health. In this sense, rabbit meat is considered healthy, as it contains a low level of fat and high levels of fatty acids, around 47% lauric acid and 18% myristic acid (32) .…”

“…According to Ferreira et al (33) , the large intestine is responsible for the fermentation processes, selective excretion of fiber (formation of cecotrophs), and its reingestion for better use. The large intestine is divided into three portions: the cecum, colon, and rectum, whose main functions are the absorption of water and minerals, production of B vitamins, and excretion of fecal matter (32) .…”

Studies that explore the use of lipids and their effects on animal nutrition have become increasingly abundant, producing a mass of information. The review was carried out on a parity basis through a survey of articles in the bibliographic databases: Web of Science and Periodicals Capes, using search terms associated or not, in the plural or singular, in English and Portuguese, such as: “lipids” AND “rabbits" AND "nutrition". After analyzing the files in the two scientific databases, certain files were excluded because they did not fit the theme or because they did not meet the inclusion criteria and repeated articles. A relevance test was carried out for the use of the articles, where they should deal with the subject: articles that report the use of lipids in the nutrition of non-ruminant animals; articles made available in complete form; articles that had at least one of the keywords; articles where the main subject is related to lipids. The articles were selected and tabulated in an Excel® spreadsheet with relevant information for exploration in the review. The use of oils and fats is a favorable point in the nutrition of non-ruminant animals, presenting benefits in the enrichment of final products such as: providing higher levels of omega-3 and omega-6, and thus obtaining meat products with lower levels of saturated fat and higher unsaturated fat contents promoting benefits to human health through its consumption, reduction of food costs, improvement in palatability and appearance of foods. These are nutritional strategies used in hot seasons of the year due to the low calorific increment produced.

“…De acordo com Ferreira et al (33) , o intestino grosso é responsável pelos processos de fermentação, excreção seletiva de fibras (formação de cecotrofos) e sua reingestão para melhor aproveitamento. O intestino grosso é dividido em três porções, o ceco, o cólon e o reto, cujas principais funções são a absorção de água e minerais, a produção de vitaminas do complexo B e a excreção de matéria fecal (32) .…”

Resumo Estudos que exploram o uso de lipídios e seus efeitos na nutrição animal têm se tornado cada vez mais abundantes, produzindo uma grande quantidade de informações. A revisão foi realizada de forma paritária por meio de uma pesquisa de artigos nas bases bibliográficas: Web of Science e Periódicos Capes, utilizando termos de busca associados ou não, no plural ou no singular, em inglês e português, tais como: "lipídios" E "coelhos" E "nutrição". Após analisar os arquivos nas duas bases científicas, determinados arquivos foram excluídos porque não se adequavam ao tema ou não atendiam aos critérios de inclusão, além de artigos repetidos. Um teste de relevância foi realizado para a seleção dos artigos, nos quais eles deveriam tratar do assunto: artigos que relatam o uso de lipídios na nutrição de animais não-ruminantes; artigos disponibilizados na forma completa; artigos que possuíam pelo menos uma das palavras-chave; artigos nos quais o assunto principal está relacionado a lipídios. Os artigos foram selecionados e tabulados em uma planilha do Excel® com informações relevantes para exploração na revisão. O uso de óleos e gorduras é um ponto favorável na nutrição de animais não-ruminantes, apresentando benefícios no enriquecimento de produtos finais, tais como: fornecer níveis mais altos de ômega-3 e ômega-6, e assim obter produtos de carne com menores teores de gordura saturada e maiores teores de gordura insaturada, promovendo benefícios para a saúde humana por meio do consumo, redução dos custos alimentares, melhoria na palatabilidade e aparência dos alimentos. Essas são estratégias nutricionais usadas nas estações quentes do ano devido ao baixo incremento calórico produzido.
