“…At 12 months, the body weight approached that reported for adult wild boars (Costa & Silva, 2006), however, lower than that described by Almeida et al (2006), also for this subspecies, which can be related to variations in the genetic profile of the animals, management and feeding, in each rearing facility.…”

“…The testicular weight observed at 12 months was lower than that described for sexually mature wild boars (Costa & Silva, 2006;Almeida et al, 2006) and adult domestic pigs (Godinho et al, 1979;Thomas & Raja, 1980;França et al . 1988;França et al 2000).…”

“…In most domestic species, the volumetric ratio of the albuginea and mediastinum is around 10% (França & Russell, 1998), which is close to the 9.4% reported for adult wild boars (Costa & Silva, 2006). Given the methodological difficulties mentioned above, the weight of the mediastinum was not taken.…”

“…Raising wild boars (Sus scrofa), collared peccaries (Tayassu tajacu) and white-lipped peccaries (Tayassu pecari) for commercial farming, besides being very profitable, can stop the illegal trade of meat, skin and other products (Costa & Silva, 2006). Despite the increasing demand and the productive potential of these species, few studies have been found in the literature about the basics of reproductive physiology and management of these animals.…”

“…Although the spermatogenesis in adult wild boars is well characterized (Almeida et al, 2006;Costa & Silva, 2006), there are no reports describing the testicular development from birth, and such knowledge can foster production, management and enhancement of reproductive efficiency, thereby reducing the cost of maintenance on farms.…”

RESUMO Biometria corporal e testicular de javalis do nascimento aos 12 meses de idadeObjetivou-se, com esta pesquisa, investigar o desenvolvimento testicular e corporal de javalis (Sus scrofa scrofa), do nascimento aos 12 meses de idade, avaliando-se, em cada faixa etária, o peso corporal, o desenvolvimento biométrico dos testículos e o índice gonadossomático (IGS). Utilizaram-se 52 javalis machos, provenientes de um criatório comercial, devidamente regulamentado pelo IBAMA. Os animais foram pesados e divididos em 13 grupos experimentais; os testículos foram coletados por orquiectomia unilateral e, em seguida, pesados em balança analítica e mensurados comprimento, largura e espessura. Os valores de peso corporal e as medidas testiculares foram crescentes, após o nascimento, sendo sua variação mais acelerada no primeiro mês e aos nove meses. Inicialmente, o padrão de crescimento testicular, do nascimento aos nove meses de idade, acompanhou o crescimento corporal e o índice gonadossomático variou de 0,07 a 0,09%. Em seguida, entre nove e 11 meses, o valor de crescimento testicular foi superior ao de crescimento corporal e o índice gonadossomático variou de 0,09 a 0,16%. Por fim, após os 11 meses de idade, os valores crescimento corporal e dos testículos voltaram a se comportar de forma semelhante. Conclui-se que o desenvolvimento do peso corporal, a biometria testicular e o IGS tiveram crescimento mais acelerado aos nove meses de idade.Palavras-chave: peso corporal, índice gonadossomático, desenvolvimento testicular, Sus scrofa scrofa. Received: 17/07/2009; Accepted: 27/12/2012 Corporal and testicular biometry in wild boar from birth to 12 months of ageThe aim of this tudy was to evaluate corporal and testicular development in wild boars (Sus scrofa scrofa) from birth to 12 months of age, evaluating body weight, biometric testicular parameters, and gonadosomatic index. Thirty-nine male wild boars from a commercial farm licensed by IBAMA were used in the study. The animals were weighed and assigned to 13 experimental groups. The testes were recovered through unilateral orchiectomy, weighed on an analytical balance and measured for length, width and thickness. Body weight and testicular measures increased with the age, up to 12 months, and were more accelerated in the first and ninth months. Initially the testicular growth pattern, between zero and nine months, followed the body growth, and the gonadosomatic index varied from 0.07 to 0.09%. Between 9 and 11 months, the testicular growth was superior to the body growth, and the gonadosomatic index varied from 0.09 to 0.16%. Finally, after 11 months of age, testicular and body growth had a similar behavior. In conclusion, body weight, testicular biometry, and gonadosomatic index development accelerated in the ninth month.
