Calves can be preconditioned using a wide variety of supplemental feed ingredients. However, feed ingredient selection is not the only factor to consider during a preconditioning process. Increasing the protein supply to stressed, preconditioning beef steers led to greater growth performance, and increased immune response to vaccination during a 42-day preconditioning period. Producers should not reduce the frequency of concentrate supplementation during the entire preconditioning period as it might lead to poorer vaccine response and average daily gain (consequently, less calf value at sale). However, a gradual reduction of frequency of supplementation is a supplementation strategy that can overcome these negative effects on growth and immunity, and allows producers to save on feeding and labor costs without producing lighter calves that have weaker immune responses.

Abstract Feed enzymes may ameliorate reduced nutrient and energy digestibility in nursery pigs. The objective was to test effects of super-dosing phytase and fiber-degrading enzymes on digestibility of DM, GE, CP, AA, and Ca. We tested supplementing a super dose (added 1,500 FYT/kg) of phytase (Ronozyme Hi-Phos) with or without carbohydrase cocktail that contained 85 FXU β-xylanase/kg, 587 U/g endo-1,4-β-glucanase, 513 U/g endo-1,3(4)-β-glucanase, 15,000 U/g hemicellulases, and 3,000 U/g pectinases in corn-soybean meal diets in a 2 × 2 factorial arrangement. Diets included 68% corn, 17% SBM, and a basal level of 500 FTU/kg of phytase, and were formulated to contain 2.50 Mcal/kg NE and 5.10 gSID Lys/Mcal NE. Eight ileal-cannulated nursery pigs (initial BW 10 kg) were fed 4 diets at 3.0 × maintenance DE (110 kcal per kg of BW0.75) for four 9-day periods in a double 4 × 4 Latin square. Apparent hindgut fermentation (AHF) was calculated as apparent total tract digestibility (ATTD) minus apparent ileal digestibility (AID). Interactions between super-dosing phytase and carbohydrase cocktail were observed. Supplementing either carbohydrase cocktail or super dose phytase, but not their combination, increased (P < 0.05) diet AID of DM, GE, CP, and most AA by 4–5%-units. Supplementing super dose phytase increased (P < 0.05) AID of P by 16%-units and ATTD of P by 10%-units. Supplementing super dose phytase or carbohydrase cocktail did not affect AID of Ca and ATTD of GE, CP, and Ca, and diet DE value. Supplementing carbohydrase cocktail without super dose phytase decreased (P < 0.05) diet AHF of DM, GE, and CP. In conclusion, dietary inclusion of super dose phytase or carbohydrase cocktail increased ileal digestibility of nutrients in nursery pigs, and thereby reduced protein entering the large intestine. Additive or synergistic effects of carbohydrase cocktail and super dose phytase were not detected.

Plasma Magnesium

Prepasture feeding of low quality hay versus hay and grain had no subsequent effect on rumen fluid ammonia, blood urea, or plasma calcium, glucose and lactic acid concentration in steers turned out on lush pasture. Steers previously fed hay and grain had lower plasma magnesium levels on the first day on unsupplemented pasture than those fed hay prior to pasture. Supplemental feed on pasture partly alleviated the depression in plasma magnesium on the first day on pasture. Feeding supplemental hay with pasture tended to lower rumen fluid ammonia, blood urea and plasma lactic acid compared with feeding no supplement during the initial days on pasture, indicating the desirability of hay feeding during this time. A hay and grain supplement with pasture had a similar effect to the hay supplement on rumen-fluid ammonia, and plasma lactic acid, but a lesser effect on blood urea concentration. Neither supplemental hay nor hay plus grain affected plasma calcium or glucose levels. All steers showed an increase in rumen fluid ammonia, blood urea and plasma lactic acid on the first day and a decrease in plasma calcium and magnesium on the second day on pasture. Blood urea, plasma magnesium and plasma calcium concentrations had not returned to prepasture levels by 21 days on pasture.

Enzymes have been successfully used to improve the nutritional value of cereal based feeds for pigs and poultry since the early eighties. Their benefits derive from improved digestion of nutrients following the destruction of anti-nutritional compounds such as β-glucans and arabinoxylans and the augmentation of the animal's existing enzyme arsenal where this may be sub-optimal. In the ruminant sphere fibrolytic enzymes have been used as aids to silage preservation for almost as long. Their action here is to enhance natural sugar levels by the breakdown of structural carbohydrates - an action which can concurrently render the fibre more amenable to digestion by rumen microbes.
