The Effect Of Sericea Lespedeza (Lespedeza Cuneata) On Eimeria Spp. Infection In Broiler Chickens, Long Nghi Trinh
The Effect Of Sericea Lespedeza (Lespedeza Cuneata) On Eimeria Spp. Infection In Broiler Chickens, Long Nghi Trinh
LSU Master's Theses
Parasites cause considerable economic losses in all fields of agriculture. In the poultry industry, coccidia infections are of major significance costing billions of dollars every year. Research on condensed tannins (CT) has been shown to be effective against various parasites such as gastrointestinal nematodes and Eimeria spp. in small ruminants. This study tested the effects of the CT containing forage, sericea lespedeza (SL), on broiler chickens infected with live Eimeria spp. oocysts. In Study 1, 300 Ross 708 broiler chicks were divided into 6 groups (negative control, positive control w/BioCox, 0% SL, 5% SL, 10% SL, 15% SL). In Study …
Influence Of Feeding Anise Oil To Piglets And Broilers, Jose Wando Charal
Influence Of Feeding Anise Oil To Piglets And Broilers, Jose Wando Charal
LSU Doctoral Dissertations
The objectives of this research were to determine 1) the effect of anise oil (AO) in pigs after exposure and re-exposure by dietary additions to sow and nursery diets; and 2) the maximum level of AO that could be fed to broilers and its effect on in-vitro growth of Clostridium perfringens (ClP); 3) to determine the effect of AO and diet type on growth performance of broilers after a challenge with ClP; and 4) to determine the effect of AO fed to broilers under commercial conditions. The results indicated that exposing lactating pigs to AO through the sow diet had …
The Use Of Serum Uric Acid As An Indicator Of Amino Acid Utilization In Diets For Broilers, Amanda L. Donsbough
The Use Of Serum Uric Acid As An Indicator Of Amino Acid Utilization In Diets For Broilers, Amanda L. Donsbough
LSU Master's Theses
The purpose of this research was to determine if serum uric acid (SUA) could be used as an indicator of amino acid (AA) utilization in broilers and to determine the Lys requirement of broilers using SUA as a response variable. Treatments were replicated with at least 6 pens with at least 6 broilers per pen. Experiments (Exp.) were conducted from 0- to 14, 17, or 18- d posthatching in brooder batteries. Five experiments were conducted to determine if SUA and uric acid content of the excreta (UAE) could be used to determine AA adequacy of a diet. The results of …
Low Crude Protein, Amino Acid-Supplemented Diets, And The Glycine Requirement In Low Crude Protein Diets For Broilers, April Marie Waguespack
Low Crude Protein, Amino Acid-Supplemented Diets, And The Glycine Requirement In Low Crude Protein Diets For Broilers, April Marie Waguespack
LSU Master's Theses
The purpose of this research was to determine the optimal level of crystalline amino acid (AA) supplementation that supports maximum growth performance in broilers, and to determine the Gly requirement in broilers. Treatments were replicated with a minimum of 7 pens with 6 broilers per pen. Experiments (Exp.) were conducted from 0- to 18- days (d) post-hatching in brooder batteries. Three Exp. were conducted to determine the maximum level of L-Lys•HCl that could be supplemented to corn-soybean meal (C-SBM) diets without negatively affecting growth performance of broilers. The results of these Exp. indicate that broilers can achieve maximum growth performance …
The Effects Of Micronutrients On Pullets And Broilers, Danielle Armantine Lauzon
The Effects Of Micronutrients On Pullets And Broilers, Danielle Armantine Lauzon
LSU Master's Theses
Two experiments were conducted to determine the availability of various vitamin E (E) sources (absorbed to verxite or adsorbed to silica) in broilers. In Experiment 1, at 100 and 300 IU supplemental E, an average of 94 and 44% of E intake from verxite and silica, respectively, was excreted in the feces, but at 30 IU E, 49 and 45% of E intake was excreted in the feces. In Experiment 2 at 30 IU, 52 and 43% of E intake from verxite and silica was excreted (source, P < 0.02). Based on these results, E adsorbed to silica is more available. Two experiments were conducted to determine the relative bioavailability of organic versus inorganic sources of either Mn or Zn. In Experiment 1, Mn as MnSO4 or a Mn amino acid complex (Availa-Mn) were compared. In Experiment 2, ZnSO4 or a Zn amino acid complex (Availa-Zn) were compared. The results indicate that Availa-Mn is a more available source of Mn than MnSO4, but Availa-Zn is not as available as a source of Zn as ZnSO4. An experiment was conducted to determine the effects of organic sources of Zn, Mn, and Cu on White Leghorn pullet performance. Treatment diets consisted of a control diet with 66 ppm Zn as ZnSO4 or a combination of ZnSO4 and Availa-Zn, 66ppm Mn as MnSO4 or a combination of MnSO4 and Availa-Mn, and 10 ppm Cu as CuSO4 or a combination of CuSO4 and a Cu amino acid complex (Availa-Cu). Diets are inorganic sources (IO), organic Zn (OZ), organic Zn and Mn (OZM), or organic Zn, Mn, and Cu (OZMC). Addition of OZM increased (P < 0.08) intestinal tensile strength and increased (P < 0.06) grams of ash per bone compared with OZMC. Pullets fed OZ had a higher (P < 0.08) bone concentration of all minerals than pullets fed OZM. Total tibia Mn was decreased (P < 0.06) by OZMC, but total tibia Cu was increased (P < 0.08) by OZ addition over IO or OZM.
The Effect Of Dietary Phosphorus Level And Phytase Supplementation On Growth Performance, Bone Breaking Strength, And Phosphorus Excretion In Broilers, Syrena Powell
LSU Master's Theses
This research was conducted to determine the effects of feeding different P levels with and without phytase supplementation on broiler growth performance, bone breaking strength (BBS), and P excretion. An experiment with 4 trials was conducted with 7,840 Ross x Ross straight run broilers. For each trial, 1,960 broilers were allotted on d 0 to 4 treatments with 7 replications per treatment with 70 broilers per replication. The broilers were fed a 4 period feeding program consisting of starter (0 to 14 d), grower (14 to 32 d), finisher (32 to 41 d), and withdrawal (41 to 50 d) periods. …
