“…Abomasal size was highly correlated with BW. This supports the findings of earlier studies in cattle (Huber, 1969;Clausen, 1999). The correlation between abomasal volume and abomasal surface area was 0.79 (P , 0.001).…”

The relationship among parasitological parameters, abomasal size and body size measurements was investigated in lambs following an experimental infection with Haemonchus contortus. In total, 100 lambs from five different genotypes (German Merino (GM), Texel 3 GM, Suffolk 3 GM, German Blackhead Mutton 3 GM and Ile de France 3 GM) were experimentally infected with 5000 infective third stage larvae of H. contortus at the time of weaning at 12 weeks of age. Four and six weeks after infection, individual faecal samples were collected for estimation of faecal egg counts (FECs). Furthermore, wither height, shoulder width, heart girth, loin girth and body length were taken at 18 weeks of life. Lambs were slaughtered and necropsied 7 weeks post-infection, and worm counts, abomasal volume and surface area were determined. Positive correlations were found between different body size parameters, body weight and abomasal sizes. FEC and worm counts were not significantly correlated either with body size parameters or with abomasal size. The mean worm burden was higher in GM than in crossbred lambs. There was no significant difference in abomasal size between GM and crossbred lambs. The results suggest that the variations between animals in worm burden following an experimental infection with H. contortus (worm resistance) are not influenced by body size parameters or abomasal sizes. Therefore, other factors, including genetic-based differences in resistance, must cause these findings between and within breeds.

“…T h e neonatal calf and lamb readily utilize lactose, glucose and galactose, whereas maltose is utilized only slightly, and fructose, sucrose and starch not at all (Dollar & Porter, 1957;Walker, 1959;Huber, 1969;Siddons, Smith, Henschel, Hill & Porter, I 969). These findings correlate well with disaccharidase activities in the intestinal wall ; ,!I-galactosidase (EC 3.2.…”

“…Nas primeiras semanas de vida de um bezerro, os processos de digestão e metabolismo estão em estado de transição, os processos característicos de monogástricos é alterado para processos típicos de ruminantes (HUBER, 1969).…”

“…Quando o animal é um ruminante não-funcional, a energia é derivada da absorção de hexose proveniente de fontes lácteas, e quando ruminante funcional os ácidos graxos de cadeia curta (AGCC) oriundos da fermentação ruminal tornam-se a mais importante fonte de energia para o animal (HUBER, 1969). Assim, a nutrição pode ser considerada como um dos principais fatores para este processo de transição, o qual é amplamente influenciado pelo consumo de matéria seca e produtos de degradação no rúmen (ANDERSON et al, 1987).…”

“…Entretanto, quando estimulado pelo consumo de concentrado inicial, por volta da quarta semana de idade, o retículo-rúmen dos bezerros passa a ocupar aproximadamente 65% do trato digestório superior, e este valor tende a aumentar para 75% na 12ª semana de idade. Este processo continua até o reticulorúmen representar cerca de 87% do volume total de um ruminante adulto (HUBER, 1969;.…”
