Twenty-four 35-day-old lambs were distributed to a completely randomized design with 3 treatments to study the effects of number of feeding buckets per pen on performance, haematology and behaviour indicators. Treatments consisted of 8 (T1), 4 (T2) or 2 (T3) feeding buckets/pen (8 lambs/pen). During the experiment, concentrate was fed at 08:30 in individual feeders. Daily dry matter intake (DMI...

Average daily gain between birth and 30 d of age of 42,644 lambs of Swiss Black-Brown Mountain Sheep were used in this analysis. The influence of amount of pedigree information on computing time and on REML estimates of population parameters was investigated on a subset of 7,848 lambs. If all available pedigree information was used, 89.4% of the lambs had at least four complete generations of k...

Palm kernel cake (PKC) is a nutrient-rich by-product of oil mills that contained high concentration copper (Cu) among other minerals elements. The higher dietary Cu was reported to impair some physiological functions in breeds sheep due toxicity. Hence, this study aimed investigate the histopathological effects PKC based diet on vital organs Dorper lambs. Fifteen male lambs (8 month-old) were r...

an experiment was carried out to evaluate how interactions between forage to concentrate ratio and dietary crude protein level may alter nitrogen efficiency and ut-b expression in growing baluchi male lambs. four baluchi male lambs [30 ± 2 kg bw] were used in a 4 × 4 latin square design with 28-d periods and a 2 × 2 factorial arrangement of dietary treatments. the treatments fed forage: concent...

Abstract Feeding high-grain diets can result in reduced ruminal pH, inflammation of and other tissues, subacute acidosis. Vasoactive intestinal polypeptide (VIP), a gut hormone with anti-inflammatory functions, could have beneficial role ruminants fed high-concentrate diets. To determine the effects VIP injection on dry matter intake, average daily gain, gain:feed, wether lambs (n=16; BW=68.5 ±...

BACKGROUND We have previously shown that nasal pressure support ventilation (nPSV) can lead to an active inspiratory laryngeal narrowing in lambs. This, in turn, can limit lung ventilation and divert air into the digestive system, with potentially deleterious consequences. On the other hand, nasal high-frequency oscillatory ventilation (nHFOV) is particularly attractive in newborns, especially ...

INTRODUCTION Clinical application of arteriovenous (AV) extracorporeal membrane oxygenation (ECMO) requires assessment of cardiovascular ability to respond adequately to the presence of an AV shunt in the face of acute lung injury (ALI). This ability may be age dependent and vary with the experimental model. We studied cardiovascular stability in a lamb model of severe ALI, comparing convention...

Sixty-four intact lambs and twenty-four lambs fitted with a duodenal cannula were weaned at 6 weeks of age and grazed pure species swards of either lucerne (Medicago sativa), white clover ((Trifolium repens), ryegrass (Lolium perenne) or prairie grass (Bromus catharticus) for 6 weeks. Intake and duodenal digesta flow were estimated when lambs were 8 and 12 weeks of age. Lambs grazing the two le...

Weaned lambs, having a detectable level of maternal antibodies (1-2 units/ml) against C. perfringens type D, showed protective antitoxin levels lasting for 29 days after receiving a single parenteral dose of 200 units/kg hyperimmune serum. Lambs, having no maternal antibodies (less than 0,07 units/ml) to C. perfringens type D but receiving the same dose of hyperimmune serum, maintained protecti...

Clostridium perfringens is a gram-positive, anaerobic bacterium that causes a wide range of diseases in humans and animals. Th e purposes of this study were to determine, using the enzyme-linked immunosorbent assay (ELISA), the clostridial toxins in intestinal samples of lambs with suspected enterotoxemia; to conduct molecular typing of C. perfringens isolates; and to investigate the presence o...
