Dietary supplementation with glutamine or glutamic acid for weanling piglets PAB
Amorim,Alessandro Borges; Saleh,Mayra Anton Dib; Miassi,Gabriela de Mello; Berto,Dirlei Antonio.
Abstract: The objective of this work was to evaluate the effects of dietary glutamine and glutamic acid supplementation on carbon turnover (δ13C) in the muscles of piglets, on animal performance, and on feed economic feasibility. The diets consisted of: control (C), 1% glutamine (G), and 1% glutamic acid (GA). In experiment I, 111 piglets were used to assess carbon turnover in the Masseter, Psoas major, and Abdominal internal oblique muscles in terms of their isotopic composition and 13C substitution over time. In experiment II, 72 piglets were assigned randomly to blocks (eight replicates per treatment and three animals per experimental unit), in order to evaluate animal performance and feed economic feasibility. The GA diet promoted the best 13C...

The objective of this study was to evaluate the effect of diets supplemented with plasma and/or yeast extract on performance (daily weight gain [DWG], daily feed intake [DFI] and feed conversion [FC]) and intestinal morphology of piglets from 7 to 63 days of age. A total of 288 piglets aged 7 days and weighing 2.57±0.05 kg were studied. A randomized block design consisting of four experimental diets, six repetitions and 12 piglets per experimental unit was adopted. The pre-starter I (7 to 21 days), pre-starter II (22 to 35 days) and starter I (36 to 49 days) diets were supplemented as follows: control diet (CD): no plasma or yeast extract; plasma (PL) diet: addition of 6%, 4% and 2% plasma; yeast extract (YE) diet: addition of 6%, 4% and 2% yeast extract;...

Enzyme complex supplementation in different nutrient levels diets on pigs feces excretion and anaerobic digestion Scientia Agricola
Ruiz,Urbano dos Santos; Thomaz,Maria Cristina; Lucas Júnior,Jorge de; Pascoal,Leonardo Augusto Fonseca; Watanabe,Pedro Henrique; Amorim,Alessandro Borges; Xavier,Cristiane de Almeida Neves; Silva,Adriane Andrade.
ABSTRACT This research aimed to evaluate enzyme supplementation in diets with different nutritional levels for pigs in their feces excretion and anaerobic digestion. Fifty four gilts were placed on diets formulated to achieve 100 or 95 or 90 % of a pig's nutrient requirements, with the addition of an enzyme complex containing amylase, β-glucanase, cellulase, pectinase, xylanase, protease and phytase (diets 100E, 95E and 90E) or without the enzymes (diets 100, 95 and 90). The trial was divided into three periods (1, 1-2 and 1-3) based on the animal weight. The enzyme complex reduced (p < 0.05) excretions per period and per unit of weight gain (residue coefficients) of organic matter (OM) in Period 1, of N, Ca, Zn and Na in Period 1-2, and of Na...

Fiber sources in diets for newly weaned piglets R. Bras. Zootec.
Pascoal,Leonardo Augusto Fonseca; Thomaz,Maria Cristina; Watanabe,Pedro Henrique; Ruiz,Urbano dos Santos; Ezequiel,Jane Maria Bertocco; Amorim,Alessandro Borges; Daniel,Everton; Masson,Guido Carlos Iselda.
This experiment was carried out to evaluate the effects of purified cellulose, soybean hulls and citrus pulp in the diet of weaned piglets. A total of 72 piglets (36 castrated males and 36 females) weaned at 21 days of age (BW 6.45±0.66 kg) was distributed according to a randomized block design, for evaluation of performance, transit time, diarrhea incidence and blood parameters of piglets which received diets containing different sources of fiber. The experimental diets were: control diet - diet composed of corn, soybean meal and a source of lactose; control + 1.5% purified cellulose; control + 3% soybean hull and control + 9% citrus pulp. The inclusion of purified cellulose, soybean hulls and citrus pulp in diets of weaned piglets did not affect the...

Glycerin levels while maintaining the electrolyte balance in finishing pig diets R. Bras. Zootec.
Leite,Rafaeli Gonçalves; Corassa,Anderson; Ton,Ana Paula Silva; Komiyama,Claudia Marie; Amorim,Alessandro Borges; Kiefer,Charles.
ABSTRACT The objective of this study was to evaluate performance and carcass and meat characteristics of finishing pigs fed diets with different levels of glycerin, while maintaining the electrolyte balance. Forty barrows with an initial weight of 97.76±13.44 kg were distributed, in a randomized block design, into four treatments with five replicates. Treatments consisted of diets containing 0, 5, 10, and 15% glycerin. Inclusions of salt and sodium bicarbonate were adjusted to balance the sodium content and maintain the same electrolyte balance of the diets as a function of glycerin inclusions. In vivo backfat thickness, daily feed intake, daily weight gain, and feed conversion were measured. After the animals were slaughtered, pH and temperature were...

Nutritional value of Brazilian distillers dried grains with solubles for pigs as determined by different methods R. Bras. Zootec.
Corassa,Anderson; Lautert,Iziz Paula Anhõn da Silva; Pina,Douglas dos Santos; Kiefer,Charles; Ton,Ana Paula Silva; Komiyama,Claudia Marie; Amorim,Alessandro Borges; Teixeira,Alexandre de Oliveira.
ABSTRACT The objective of this study was to determine the digestibility coefficient (DC) of nutrients and the digestible energy (DE), and metabolizable energy (ME) values of distillers dried grains with solubles (DDGS) produced in Brazil by different methods. Eight barrows with 23.3±4.1 kg were housed in metabolic cages in a randomized block design and fed diets containing 0, 200, 400, and 600 g kg–1 of corn DDGS. We determined the digestibility of dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), mineral matter (MM), neutral detergent fiber (NDF), and gross energy (GE) by the total collection (TC) and chromium oxide marker (Cr) methods. Distillers dried grains with solubles provided the respective DM, OM, CP, EE, MM, NDF, and...

Nutritional value of distillers dried grains with solubles from corn and sorghum and xylanase in diets for pigs R. Bras. Zootec.
Corassa,Anderson; Stuani,Jessika Lucia; Ton,Ana Paula Silva; Kiefer,Charles; Sbardella,Maicon; Brito,Claudson Oliveira; Amorim,Alessandro Borges; Gonçalves,Diésica Bianca Coelho.
ABSTRACT Two experiments were conducted to evaluate the digestibility and energy of distillers dried grains with solubles (DDGS) from corn and sorghum with or without xylanase enzyme in diets for pigs. The values of dry matter (DM), organic matter (OM), crude protein (CP), mineral matter (MM), ether extract (EE), neutral detergent fiber (NDF), gross (GE), digestible (DE), metabolizable energy (ME), and digestibility coefficients (DC) were determined. In the experiment 1, we used eight barrows of 26.15±3.45 kg with repeated measures in three periods of five days of collection. The treatments consisted of a reference diet (RD); RD with 200 g kg−1 corn DDGS or sorghum DDGS; and RD with 400 g kg−1 corn DDGS or sorghum DDGS. Corn DDGS showed higher values of...

Purified cellulose, soybean hulls and citrus pulp as a source of fiber for weaned piglets Scientia Agricola
Pascoal,Leonardo Augusto Fonseca; Thomaz,Maria Cristina; Watanabe,Pedro Henrique; Ruiz,Urbano dos Santos; Amorim,Alessandro Borges; Daniel,Everton; Silva,Susana Zaneti da.
Dietary fiber is an important component, which has a direct effect on intake, digestion, and absorption of nutrients; and also alters intestinal microbiota and morphology according to solubility. One digestibility trial and one performance experiment were performed to evaluate the effects of sources of fiber in diets for 21 day weaned piglets. The experimental diets used in both trials consisted of a control diet and diets with purified cellulose, soybean hulls or citrus pulp as a main source of dietary fiber. To evaluate the digestibility of nutrients (Assay 1), the total feces and urine collection method was used. The fiber sources did not affect nutrient digestibility, except for soluble fiber, which increased with the inclusion of citrus (Citrus...
