| The objective of this study was to evaluate the flow of nitrogenous compounds, protein degradability, rumen degradation of total carbohydrate and organic matter and microbial efficiency in heifers subjected to diets containing corn silage, sugarcane or Tifton. For this purpose, the 2,6-diaminopimelic acid (DAPA) technique was adopted and analytical procedures for amino acids by HPLC were adapted. Six rumen-fistulated Holstein-Zebu heifers with 480 kg of initial BW and at 24 months of age kept in individual tie stalls were assigned to two 3 × 3 Latin squares. Omasal digesta dry matter and microbial dry matter flows were determined using the isolated, purified and enriched lignin (LIPE®) and DAPA markers, respectively. Isolated bacteria from rumen showed on... |

| The objective of this study was to evaluate the utilization of different sources of unsaturated long-chain fatty acids in diets for dairy cows during the transition period and early lactation on the milk fatty acid profile and composition of the protein fraction. Thirty-six Holstein cows were divided into three groups, fed the following diets: control (C); soybean oil (SO); and calcium salts of long-chain unsaturated fatty acids (CS). The milk samples utilized for analysis were obtained weekly from parturition to twelve weeks of lactation; each one of the samples originated from two daily milkings. Milk composition and total nitrogen, non-protein nitrogen and non-casein nitrogen levels were analyzed. The cows receiving the diet with calcium salts had lower... |

| Among tropical forages, corn silage is largely used by farmers trying to explore the maximum genetic potential from the animals. However, other tropical forages, such as elephant-grass (Pennisetum purpureum), are more productive and therefore cheaper to use than corn silage. Our objective was to compare the in situ degradability of elephant-grass with that from corn hybrids, all harvested at four stages of maturity. The experimental design followed a randomized block design with nested subplots. Two corn hybrids: AG5011, ZN8392 were harvested with 25, 30, 35, and 40% dry matter (DM) in the whole plant, and separated in stem + leaf sheath + leaf blade (stover), and cobs. Elephant-grass was harvested with 30, 40, 50 and 60 days after a leveling cut. Dried... |

| This study was developed to evaluate the ingestive behavior of beef cattle finished in feedlots with different concentrate levels in the diet. Sixteen bulls fed 22, 40, 59, or 79% of concentrate in the diet were assigned to a complete randomized design, with four replicates each. The supplied diets were isoproteic and the roughage used was corn silage. Data collection was carried out during the finishing period, with a total of six days. The time given to food intake, rumination, the number of bouts per meal and neutral detergent fiber rumination efficiency decreased linearly as the concentrate levels in the diet increased. Idle time increased linearly accordingly to the increment of concentrate in the diet. The animals have greater feed intake and... |

| Abstract Legume silage can increase the forage quality of the diets as well as supply it with nitrogen, calcium and phosphorus. The objective was to evaluate the intake, apparent digestibility, rumen fermentation and nitrogen efficiency in sheep fed a tropical legume silage with or without concentrate. Twelve crossbred sheep with an average initial body weight of 32.2 ± 1.26 kg, with six animals cannulated in the rumen were distributed into four 3 × 3 Latin squares. The treatments were 1) Stylosanthes silage without concentrate (StS), 2) Stylosanthes silage with concentrate (StS+C), and 3) corn silage with concentrate (CS+C). StS diet showed lowest intake, except for neutral detergent fiber (NDF). The diets StS+C and CS+C showed similar intake of dry... |

| Current trial evaluated yield, organic matter and mineral composition of the residual harvest of five maize hybrids at three cutting heights (15, 35 and 55 cm). The experimental design consisted of a randomized block split plot with three replications. Concentrations of N, P, K, Ca, MS, MM and MO in the samples were evaluated. No difference among hybrids occurred in stem diameter (22.4 mm), ear production (8.0 ton DM ha-1), grain harvest index (37.3%) and total forage yield (15.0 ton DM ha-1). Hybrid effect occurred for variables of mineral composition of harvest residues. With the exception of calcium, a rise in cutting height from 15 to 55 cm failed to increase the concentration of minerals in the residue. The amount of organic matter and mineral... |

| Animal performance is the most direct measure in the evaluation of feed quality. However, performance data are often insufficient to determine possible interactions that may take place in the ruminal environment. The purpose of the present trial was to evaluate the possible associative effects on the concentrations of volatile fatty acids (VFAs), ammoniacal nitrogen (N-NH3) and pH in the remaining liquid fraction from the dry matter (DM) digestion for exclusive roughages: sugarcane (SC), 60- (EG60) and 180-day elephantgrass (EG180), and corn silage (SIL), as well as for combined roughages: sugarcane+corn silage (SCSIL), sugarcane+60-day elephantgrass (SCEG60), sugarcane+180-day elephantgrass (SCEG180), corn silage+60-day elephantgrass (SILEG60), corn... |

| ABSTRACT Forty eight crossbred calves, 24 males and 24 females, with weight and age of 203.6±3.7kg and 11.8±1.0 months were allotted to the following treatments: MT- mineral salt ad libitum and sugar cane mixed with 10g kg-1 mixture of urea and ammonium sulfate in a 9:1 proportion; MA - sugar cane mixed with 16g kg-1 of a concentrate of urea (550g kg-1), ammonium sulfate (60g kg-1) and minerals (390g kg-1); SU - sugar cane mixed with 50g kg-1 of a concentrate of soybean meal (830g kg-1), urea (52g kg-1) and minerals (118g kg-1) and MC - corn silage mixed with 10g kg-1 of a concentrate of urea (500g kg-1), ammonium sulfate (50g kg-1) and minerals (450g kg-1). Minerals mixed with sugar cane (MA) resulted in greater weight gain (0.258 x 0.188kg d-1) for... |

| The objective was to evaluate the effect of the ratio of degradable intake protein (DIP) to non-structural carbohydrate (NSC) on the nitrogen flows to duodenum of steers by replacement alfalfa silage with corn silage. Six Holstein steers fitted with ruminal and duodenal cannulae were divided into two 3 x 3 Latin squares with 20d periods. In the first Latin squareï¼ the steers were fed three diets contained (dry matter basis): 1) 100% alfalfa silage (AS100)ï¼ 2) 80% alfalfa silageï¼ 20% corn silage (AS80)ï¼ or 3) 60% alfalfa silageï¼ 40% corn silage (AS60). In the another Latin squareï¼ the steers were fed three diets contained (dry matter basis): 1) 40% alfalfa silageï¼ 60% corn silage (AS40)ï¼ 2) 20% alfalfa silageï¼ 80% corn silage (AS20) or 100% corn... |

| The objective was to evaluate the effect of different proportion of alfalfa silage and corn silage on the nitrogen utilization and milk production of dairy cows. Eighteen lactating Holstein cows were divided into three treatment groups. The cows in the three treatment groups were fed mixture of alfalfa silage and corn silage，which were formulated (dry matter basis) at 1) 80:20 (AS80)，2) 60:40 (AS60) and 3) 40:60 (AS40) ratios，respectively. Grass hay and concentrate were fed also to adjust silage ratio (65% of total DM)，roughage ratio (70% of total DM) and CP contents (15%DM) of the diets among AS80，AS60 and AS40. The ratio of degradable intake protein (DIP) to non-fibrous carbohydrate (NFC) in AS80，AS60 and AS40 were 0.27，0.27 and 0.28，respectively. Milk... |
