SUMMARY Citrus pulp can replace corn in feedlot diets in order to decrease metabolic problems by reducing formation of lactate ruminal. However, while eating, animals can easily select against pelleted citrus pulp due to the greater particle size of the pellet. Therefore, grinding citrus pulp pellet can be an alternative to decrease particle selectivity. This study was realized to evaluate the replacement of ground corn by pelleted citrus pulp and ground citrus pulp on animal performance, sorting index, and feeding behavior of Nellore heifers. Thirty-six Nellore heifers were randomly assigned to three treatments: control diet based on ground corn (GC), partial replacement of GC by ground citrus pulp (GCP), and partial replacement of GC by pelleted citrus pulp (PCP). . Heifers fed with the GC diet had higher final body weight (BW), average daily gain (ADG), and dry matter intake (DMI) compared with heifers fed with citrus pulp (P < 0.05). Ground citrus pulp increased DMI and fiber intake compared with the PCP group (P < 0.05). Heifers fed with PCP and GCP sorted for diet particles from 8 to 19 mm and selected particles with less than 1.18 mm (P < 0.05). Thus, the ground citrus pulp is better than pelleted citrus pulp due to higher feed intake and ADG, in consequence of lower selection index.

ABSTRACT: The objective in this trial was to determine the effects of partial replacement of ground corn by citrus pulp or soybean hulls on performance and carcass characteristics of feedlot goat kids. Twenty one Boer x Saanen kids (initial BW 15.8 ± 0.7kg), nine males and 12 females, were distributed in a complete randomized block design, according to sex and initial body weight. Treatments were set by replacing 50% of ground corn (DM basis) for citrus pulp or soybean hulls; whereas, forage concentrate ratio was of 10:90. Partial replacement of corn by citrus pulp or soybean hulls increased dry matter intake, average daily gain and final body weight, but feed efficiency was not affected. There was no difference between citrus pulp or soybean hulls. Inclusion of coproducts increased slaughter weight, hot and cold carcass weight and longissimus muscle area, with no difference between citrus pulp and soybean hulls. Subcutaneous fat thickness, hot and cold carcass yields, shrink after chilling and body wall thickness were not affected by treatments. Citrus pulp and soybean hulls can replace 50% of ground corn (DM basis) increasing dry matter intake and weight gain in goat kids enabling higher slaughter weight at earlier age.

Abstract An experiment was conducted to test the hypothesis that addition of Val, Ile, or Trp alone or in combination will reduce the negative effects of excess Leu in diets for growing pigs. A total of 288 growing pigs (28.6 ± 2.5 kg) were randomly assigned to 1 of 9 dietary treatments in a randomized complete block design. There were 2 barrows and 2 gilts in each pen and 8 replicate pens per treatment. A control diet based on corn and soybean meal and 8 diets based on corn and a high-protein corn product (48% crude protein) with 2 levels of crystalline L-Val (0 or 0.10%), L-Ile (0 or 0.10%), and L-Trp (0 or 0.05%) were formulated. The crystalline L-Val, L-Ile, and L-Trp increased standardized ileal digestible (SID) Val:Lys from 70 to 80%, SID Ile:Lys from 53 to 63%, and SID Trp:Lys from 18 to 23%, respectively. All diets were formulated to contain 1.00% SID Lys and the 8 diets containing corn protein contained 171% SID Leu:Lys. Individual pig weights were recorded at the beginning and at the conclusion of the 28-d experiment. Data were analyzed using the PROC MIXED of SAS with a pen as the experimental unit. Diet was the fixed effect and block and replicate within block were random effects. Results indicated that final body weight and average daily gain were not different between pigs fed the control diet and pigs fed the diet with Val and Trp addition, but greater (P &lt; 0.001) than for pigs fed the diet with Val addition, Ile addition, Trp addition, Val and Ile addition, Ile and Trp addition, or Val, Ile, and Trp addition (Table 1). In conclusion, addition of Val and Trp to diets with excess Leu may prevent negative effects of excess Leu in diets for growing pigs.

This experiment was conducted to evaluate the effects of corn or soybean hull incorporation into haylage-based diets on backgrounding calf performance and subsequent feedlot performance. Crossbred steers [n = 48, initial body weight (BW) = 303 ± 3.4 kg] were individually fed dietary treatments consisting of: (1) haylage [17.5% crude protein, dry matter (DM) basis; control], (2) haylage + 20% (DM basis) cracked corn, and (3) haylage + 20% (DM basis) soybean hulls during a 112-d backgrounding period. After the backgrounding period, all steers were adapted to a common high moisture corn-based finishing diet and fed until an ultrasound estimated backfat thickness of 7 mm was obtained. During the backgrounding period, steers fed cracked corn or soybean hulls had greater (P < 0.01) average daily gain, dry matter intake and gain:feed and lower (P = 0.05) plasma urea N as compared with controls. However, when finished on a common high-concentrate diet, steers previously fed cracked corn had greater (P < 0.08) average daily gain, final body weight, and longissimus muscle area than those fed soybean hulls, suggesting that source of supplemental energy during the backgrounding period may influence subsequent feedlot performance.

Twenty-eight Saanen goat kids (16 non-castrated males and 12 females; 14.38±1.60 kg) were used to evaluate the performance and nutritional value of diets. Animals were randomly allotted into a 4x2 (diets x gender) factorial arrangement. Treatments consisted of four different total mixed diets composed of oat hay, soybean meal, mineral supplement, and/or oilseeds replacing ground corn (on dry matter basis), as follows: 1) control (without oilseeds), 2) diet containing 7.9% flaxseed, 3) diet with 7.3% sunflower, and 4) diet containing 8.0% canola. Dry matter intake was higher for animals receiving control diet. Gender did not influence dry matter and nutrient intake. Oilseeds did not affect the average daily gain (ADG) and feed conversion (FC). Flaxseed diet showed more days in feedlot. Males showed better means of ADG, FC and days in feedlot. Diets containing oilseeds had higher values for ether extract digestibility and lower total carbohydrates than the control diet. The energetic value of diets did not alter. The inclusion of flaxseed, sunflower or canola in diets of Saanen goat kids in place (8% on a DM basis) corn, does not improve the performance, however these oilseeds may be used without changing the nutritional value of diets.

Supplementing a control diet of ground alfalfa (CON) with monensin (MON), chlortetracycline (CTC) or tylosin (TYL) did not affect (P < 0.05) dry matter intake or average daily gain of market lambs. Feed efficiency with CTC was less than with the unsupplemented control (CON) (6.22 vs. 5.68) (P < 0.05). Mean digestibilities of dry matter, acid detergent fiber and neutral detergent fiber were lower (P < 0.05) with all antibiotic treatments than the CON diet. Relative to CON, nitrogen digestibility was increased with MON (66.3 vs. 70.9%) while that of energy was reduced with TYL (P < 0.05). Rumen ammonia and acetic, propionic and butyric acid concentrations were not influenced by any of the treatments. MON, CTC and TYL were not effective supplements for lambs fed alfalfa finishing diets. Key words: lamb, chlortetracycline, monensin, tylosin, alfalfa hay, digestibility

Ninety-six Yorkshire barrows and gilts were used in each of two experiments conducted in the spring-summer (exp. 1), and fall-winter (exp. 2) months, respectively, to evaluate 15% Tower rapeseed meal (RSM) as a partial replacement for soybean meal (SBM) on an isonitrogenous basis in corn-based diets for pigs from 23 to 91 kg body weight. At 91 kg, half the number of pigs in each dietary group were slaughtered. Then, three levels of protein (12, 14 and 16%) in both corn-SBM and corn-SBM-RSM diets were fed to the remaining pigs in each group up to a final body weight of 125 kg. The energy level in the RSM diets was not adjusted to equal that in the SBM diets. In the 23- to 91-kg gain period, average daily gain (ADG) (P < 0.01) and backfat (P < 0.05) were lower in the RSM-fed pigs compared to SBM-fed pigs only in exp. 2. From 91 to 125 kg body weight, ADG (P < 0.05), feed intake (P < 0.01) and backfat (P < 0.01) were lower for RSM-fed pigs only in exp. 2. The heavy weight pigs fed RSM diets had a lower (P < 0.01) dressing percentage than SBM fed pigs in exp. 1. Reduction of dietary protein from the 16% fed up to 91 kg body weight to either 14 or 12% in the 91- to 125-kg gain period did not affect performance.

Entire male (EM) pigs (152; ∼30 kg body weight) were used to examine immunocastration using Improvest and feeding ractopamine on growth performance, carcass and meat quality, and fatty acid composition. Timing for administering second dose of Improvest compared dosing at 4 and 8 wk pre-slaughter. A factorial arrangement evaluated two genotypes [Large Whites and Duroc crossbreds (Durocs)] by five management regimens (EM fed control diet, EM fed ractopamine, second dose Improvest 4 wk pre-slaughter, second dose Improvest 8 wk pre-slaughter, second dose Improvest 4 wk pre-slaughter plus ractopamine). Average daily gain and gain to feed (G:F) were generally greater (P ≤ 0.01) in Durocs. Immunocastration increased (P < 0.01) dry matter intake (DMI); feeding ractopamine decreased (P < 0.02) DMI and increased (P < 0.03) G:F. Immunocastration decreased (P < 0.04) carcass and lean yields; feeding ractopamine increased (P < 0.04) carcass weights, lean yield, muscling, and longissimus shear force while decreasing (P < 0.01) backfats. Immunocastration did not affect loin pH, color, drip loss, and shear force. Timing for second Improvest dose did not affect most growth performance, carcass, and meat quality traits except for greater (P < 0.02) backfats when administering dose 8 wk pre-slaughter. Effects of immunocastration and (or) feeding ractopamine were relatively consistent in both genotypes evaluated.

The study evaluated the effect of a phytase supplement, produced by Aspergillus niger, on the performance of 72 growing-finishing pigs (28-101 kg). Chemical and physical parameters of the tibia and fibula bones were measured. The control diet (diet 1) was formulated to be adequate for pigs with respect to all nutrients, and diets 2 and 3 with respect to all other nutrients except total phosphorus (P). The P source of the control diet was dicalciumphosphate (dihydrate), while no inorganic P was added to diets 2 and 3. Diet 3 was supplemented with phytase, 720 U/kg feed. The average daily gain (ADG) and the feed conversion ratio (FCR) of the control pigs were significantly better than those of the groups without inorganic P. Phytase improved the ADG (p

Abstract The objective of this trial was to evaluate the effects of increasing levels of narasin in the diet of lactating ewes on dry matter intake (DMI) and average daily gain (ADG) of their lambs. Forty crossbred ewes Dorper x Santa Inês with their lambs were assigned to a randomized complete block design (10 blocks and 4 treatments). The treatments were defined by the inclusion of narasin to a base diet (16.8 ± 0.66 of CP) containing 50% of concentrate and 50% of Brachiaria brizanta hay, as follow: 0N - control diet; 13N - 13 mg of narasin/kg of DM; 20N - 20 mg of narasin/kg of DM; 27N - 27 mg of narasin/kg of DM. The experiment lasted from 14 to 70 days of lactation. From the second to the tenth week of age the lambs received initial concentrate (57.0% corn; 25.0% soybean meal; 1.5% limestone; 1.5% of mineral mix; 5.0% of sugarcane molasses and 10% of milk replacer; composition: DM=89.3%; CP = 21.1%; FDN = 8.9%; FDA=2.7%) (ad libitum) in a private feeder. All data were analyzed using the MIXED procedure of SAS. The lambs were weighed weekly after 5-hours fasting. The orts were quantified weekly to determine the DMI. There was no effect of the supply of narasin to the ewes on the DMI by the lambs (0N = 0.126; 13N = 0.088; 20N = 0.153; 27N = 0.145 kg/d; P &gt; 0.05). However, the supply of narasin decreased the ADG (0N = 269.3; 13N = 259.60; 20N = 264.02; 27 = 228.01 g; P &lt; 0.01) of lambs. In conclusion, the use of narasin for the ewes did not benefit lamb performance.

Pectin industry generates a citrus pulp residue compounded by peduncle, endocarp, juice vesicles, columella, seeds and tiny fractions of epicarp and mesocarp of citrus fruits, denominated Wet Citrus Pulp (WCP), which has not yet been tested as food for lamb’s nutrition. Thus, this study aimed to determine the effect of partial replacement of ground corn by WCP in high-concentrate diets on the performance and hepatic enzyme concentration of feedlot lambs. Forty-two male lambs (15 Santa Inês and 27 ½ Dorper × Santa Inês), with 24.7 ± 1.5 kg of BW and 60 ± 5 d of age was assigned to a randomized complete block design. Within blocks (n = 14), lambs were randomly assigned to 1 of 3 treatments: 0WCP (control) – diet containing 75.5% ground corn without WCP; 20WCP – diet containing 20% WCP in replacement of ground corn, and 40WCP – diet containing 40% WCP in replacement of ground corn. The experiment lasted 70 days, which was split in 3 experimental periods (14 days of diets’ adaptation and 2 sub-periods of 28 days each). Statistical analyses were performed using the MIXED procedure of the SAS. Orthogonal polynomials for diet response were determined by linear and quadratic effects. There was a quadratic effect for DM, CP, ash, ether extract and NFC intake The highest DM and CP intake was observed for lambs fed 20WCP, however, the control diet increased the ash, ether extract and NFC intake. The increased levels of WCP decreased the ADG and feed efficiency (FE) during the adaptation period, however, did not affect the ADG and FE on periods 1 and 2. Consequently, the increased levels of WCP inclusion decreased linearly the BW. There was no effect of WCP inclusion in diets on Gamma-Glutamyl Transferase (GGT) concentration. However, there was a linear increase for Aspartate Aminotransferase (AST) concentration during the adaptation period, but without difference in other periods. In conclusion, adding up to 40% of WCP in finishing diets for feedlot lambs decrease performance during adaptation period, compromising the final body weight, but without damages effects on liver enzymes.
