Effect Of Feeding

Abstract A 2 × 2 factorial digestion study using seven ruminally cannulated steers evaluated the effect of feeding diets containing 70% (dry matter-basis) high-moisture (HMC) or dry corn (DC), processed with either a hammer mill or Automatic Ag Roller Mill (Pender, NE), on nutrient digestion. Feeding HMC decreased the amount of excreted dry matter (DM) and organic matter (OM; P ≤ 0.01) regardless of mill type, but there was a tendency (P ≤ 0.13) for an interaction between corn type and mill type for DM and OM digestibility. There was no difference between either milling treatments fed as HMC (P ≥ 0.69), but the hammer mill DC diet was more digestible than the roller mill DC (P = 0.05). There was no effect on NDF digestibility, but there was a tendency for an interaction between grain type and processing method for ADF digestibility, with the roller mill DC diet having the lowest (P = 0.02) ADF digestibility and no differences (P ≥ 0.15) among the other treatments. As expected, HMC based diets had greater (P < 0.01) starch digestibility compared to DC, but milling method had no effect (P = 0.56). High moisture corn diets had greater (P = 0.01) DE intake (Mcal/kg), and hammer mill DC tended to be greater (P = 0.07) than roller mill DC. There tended (P = 0.07) to be an interaction for minimum pH, with roller mill HMC and hammer mill DC having the lowest average pH, but not different from hammer mill HMC (P ≥ 0.32). There were no differences (P = 0.56) in average pH, but HMC diets had greater variance (P = 0.04) and greater area under pH 5.6 (P = 0.05) compared to DC based diets. Feeding cattle HMC compared to DC increases nutrient digestibility but milling process had little impact.

This experiment studied the effect of grind mill type [hammer (HM) or attrition (AM)], grind size (5.6 mm 4.8 mm, and 2.4 mm) and wheat type [Durum or Hard Red Spring (HRS)] on the performance, energy retention (AME), and the gut development of broilers fed these diets with or without 1.2 g water-1 g dry feed added. Twenty-four dietary treatments (2 grind types × 3 grind sizes × 2 wheat types × wet or dry feeding) were each fed to four cages of six male broilers from 1 to 17 d of age. Wet diets were prepared daily. Feeding diets with water increased 17 d body weight and feed intake of broilers compared with feeding the diets dry. Body weight and feed intake of broilers fed the HM diets were greater than those of broilers fed diets containing wheat processed by AM. Feed intake and FCR with HRS-based diets were higher than those for Durum-based diets. The AME for Durum was higher than for HRS and the ME efficiency (kcal g-1 BW) was greater, indicating a lower efficiency. The AME intake of HM ground wheat was higher than for that for wheat ground with the AM. The type of grinding, the wheat type, and the addition of water all affected the length and weight of the digestive system, likely through their effects on the rate of water absorption and passage through the gut. Particle size did not affect any measurement. Hammer milling produced a uniform particle size and less fines and may be better suited for processing wheat in broiler diets.
