Replacement heifers-Health program

Common disease causing agents are identified and a sample replacement heifer health program is presented. Written objectives are useful for evaluation of heifer rearing.; Dairy Day, 1986, Kansas State University, Manhattan, KS, 1986;

Effects of monensin and sodium propionate on net nutrient absorption in steers fed high-grain diets

Adding either monensin or sodium propionate alone or in combination to the diet of steers fed high-grain diets resulted in increased net absorption of glucose. Monensin reduced ammonia output and gut uptake of urea. We propose that increased propionate availability reduces the utilization of glucose by gut tissues. allowing more glucose to reach the portal system. These changes...

Influence of ionophore addition to high-grain diets on net nutrient absorption

Adding ionophores to a high grain diet increased glucose absorption and decreased the transport of urea back into the gut. These changes are consistent with the antibiotic effects of these compounds. Decreased microbial activity in the gut and shifts in the pattern of absorbed nutrients may help explain the improvements in feed efficiency seen with ionophore addition.

Influence of ionophore addition to a high-concentrate diet on net nutrient absorption in steers

Feeding the ionophores monensin and lasalocid In a high-concentrate diet resulted in gut tissues utilizing less glucose. Monensin caused less urea to be recycled. The new, experimental ionophore (lCI 139603) resulted in an increased net absorption of acetate. Thus, ionophores may differ in how they execute their effects on feed efficiency.

Feeding value of wheat and sorghum grain as indicated by absorbed nutrients

Steers fed diets based on dry-rolled wheat or sorghum grain alone or combined (50:50) showed no differences in net portal fluxes of glucose, L-lactate, ammonia, urea, or α-amino nitrogen. Portal blood flow was increased in steers fed the 50:50 diet. Total volatile fatty acid flux into the portal blood tended to be lower for steers fed the sorghum grain diet, which may partially...

Experimental induction and monitoring of liver abscesses in cattle with ultrasonography

We have demonstrated that ultrasonography can be used to visualize liver abscess in live cattle. We have also developed a nonsurgical method of catheterizing the bovine portal vein and experimentally inducing liver abscesses by inoculating the portal vein with Fusobacterium necrophorum bacteria.

Influence of supplemental grain type on forage utilization by beef steers consuming early summer bluestem

Supplementation of early summer bluestem with low levels of corn, wheat, or sorghum grain had no effect on forage intake, forage digestibility, or total dry matter digestibility in beef steers, compared with a regimen of no supplementation. Increased total dry matter intakes for the supplemented steers reflected supplement consumption.

Glucose, starch, and dextrin utilization in the small intestine of steers

Glucose infused into the abomasum of Holstein steers resulted in higher arterial glucose concentrations and increased net glucose absorption than either starch or dextrin infusions. Increasing infusion rates above 20 g/hr for both starch and dextrin resulted in no further increases in net glucose absorption. Even though the enzymatic starch and dextrin hydrolysis became saturated...

Glucose. starch, and dextrin utilization in the small intestine of steers

Holstein steers (775 lbs) were surgically fitted with abomasal and ileal cannulae, portal and mesenteric venous catheters, and an elevated carotid artery. These steers were used to study starch digestion in the small intestine. Glucose, corn starch, and corn dextrin were infused into the abomasum at various levels and ileal digesta samples were collected. Disappearance of...
