Change of skeletal dimensions during growth in sheep: the effect of nutrition

Abstract: S U M M A R YMeasurements of skeletal size were made at 2-3-month intervals on 30 Border Leicester x Merino castrate male (wether) sheep between 2 and 27 months of age. Fifteen sheep were fed ad libitum on a high-quality diet and the other 15 half the average amount consumed by the first group, age for age. The ad libitum group grew faster and were larger in all body dimensions on each occasion, except for leg length at 27 months which showed no statistical difference between groups. When the groups were compa… Show more

“…Before slaughtering, lambs were weighed again to obtain the weight at slaughter (WS) and fasting loss weight (FLW), then they were evaluated in the following morphological measurements: body length (distance in centimeters between neck base, joint and cervicothoracic tail base, first joint intercoccigea), height above (distance between the withers and distal forelimb), rump height (distance between the sacral tuberosity, on the rump, and the distal hind limb), heart girth (measured after the scapula), rump width (maximum width between the trochanters of the femurs) and chest width (distance between the sides of the scapular-humeral joint) (SEARLE; GRAHAM; DONNELLY, 1989;OSÓRIO, 1998;YÁÑEZ et al, 2004). Measurements were obtained with the lambs positioned on a flat and horizontal surface, by the same evaluator in order to minimize errors.…”

“…Animals were weighed on a digital scale suitable for small ruminants and the biometric measurements (body weight, thoracic circumference, anterior and posterior heights) were performed with the aid of tape measure, as suggested by Searle et al (1989).…”

“…No início do experimento, ao final da restrição e ao final da realimentação, foram registradas as seguintes medidas biométricas (Searle et al, 1989;Yáñez et al, 2004) das cordeiras: altura da cernelha (distância entre a região da cernelha e a extremidade distal do membro anterior) e altura do vazio subesternal (distância entre o solo e o esterno), obtidas com uso de uma régua ovimétrica; profundidade torácica (diferença entre a altura de cernelha e a altura do vazio), comprimento corporal (distância entre a articulação cérvico-torácica e a base da cauda na primeira articulação intercoccígea) e perímetro torácico (perímetro tomando-se como base o esterno e a cernelha), medidos com fita métrica; e largura da garupa (distância entre os trocânteres maiores dos fêmures) e do ombro (distância entre as faces laterais das articulações escápulo-umerais), determinada com o uso de um compasso. A condição corporal foi estimada de acordo com Russel et al (1969) e Ribeiro et al (2003) e consistiu na palpação da região dorsal da coluna vertebral, verificando-se a quantidade de gordura e músculo no ângulo formado pelos processos dorsais e transversos, atribuindo-se nota de 1 a 5 ± 0,5, em que 1 representa um animal caquético e 5 , um animal obeso.…”
