A total of 45 lactating Holstein cows averaging 617 kg of BW were allotted at wk 20 of lactation to 9 groups of 5 cows blocked for similar DIM to determine the effects of feeding different concentrations of flax hulls (FH) on DMI, milk production, milk composition, and digestion. Cows within each block were assigned to one of the 5 isoenergetic TMR containing 0, 5, 10, 15 or 20% FH. The experim...

Ruminants can be safely anesthetized in a field setting. The higher level of analgesia provided by anesthesia eliminates the need for local anesthetic blockade, which can prove useful when a procedure is expected to produce a substantial level of pain or local anesthetic blockade is not feasible. Certain aspects of anesthesia place the patient at greater risk than chemical restraint techniques....

Feed additives are largely used in beef cattle diets to improve performance and reduce risks of nutritional disorder diseases like acidosis and timpanism. However, some countries tend to ban the use of ionophore in animal nutrition due to the risk of resistance of some microorganisms. Therefore, alternatives to non-antibiotic additives must be studied. The objective of this work was to investig...

An experiment was conducted to determine the effects of unsaturated fatty acids supplementation on growth performance and carcass characteristics of finishing lambs. Thirty-two finishing Afshari lambs (initial weigh 58 ± 5 kg and 8 mo age) were used in a completely randomized design with 4 treatments (slaughtered in time series) and 8 lambs/treatment for the final 30 d before slaughter. The sla...

The absorption of peptides by the ruminant gastrointestinal tract is an important physiological process. The breakdown of proteins by m e n microorganisms gives rise to peptides, and recent observations suggest that these peptides make a significant contribution to non-ammonia nitrogen flow to the small intestine, and are available for absorption [I]. In the intestine of non-ruminant species th...

BACKGROUND Adequate feeding is essential to realizing the potential of small ruminants to alleviate poverty among smallholder farmers. This study was conducted in two villages in the Ejura-Sekyedumase District of Ghana and was motivated by farmers' non-adoption of modern feed technologies, but more importantly by the need to understand the small ruminant feed system considering farmers' differe...

The question posed by the title of the paper is in essence a simple one: is it possible, from chemical and physical analysis of the diet, to predict the rate of growth of the ruminant animal? The beguiling simplicity of the question is soon dissipated in view of the ruminant mode of digestion and the transformation of the ingested nutrients to alternate forms for absorption and the subsequent s...
