“…Monosodium l-glutamate is the principal source of the umami taste, which increases intensity and acceptability of inherent flavors of food. In a follow-up study, addition of monosodium l-glutamate to an associated commercial flavor in creep feed did not elicit any effect on creep feed intake or preweaning performance (Gatel and Guion, 1990). Results of the current study agree with those previous findings.…”

In Exp. 1, 50 sows and their litters were used to determine the effects of adding a feed flavor to the creep diet on the proportion of pigs consuming creep feed ("eaters") and preweaning performance. Sows were blocked according to parity and date of farrowing and allotted to 2 experimental treatments: 1) litters fed a creep diet with no flavor (negative control) or 2) negative control diet with the feed flavor (Luctarom) included at 1,500 mg/kg. Both creep diets contained 1.0% chromic oxide and were offered ad libitum from d 18 until weaning at d 21. Adding flavor to the creep diet did not (P > 0.41) affect weaning weights, total BW gain, ADG, total creep feed intake, daily creep feed intake, or the proportion of creep feed eaters in whole litters. In Exp. 2, 480 weanling pigs (6.58 ± 0.41 kg; 20 ± 2 d) from Exp. 1 were randomly selected by preweaning treatment group, blocked by initial BW, and allotted to 1 of 8 treatments in a randomized complete block design to determine the interactive effects of preweaning exposure to flavor (exposed vs. unexposed), nursery diet complexity (complex vs. simple), and flavor addition to nursery diets (with vs. without flavor). Each treatment had 10 replications (pens) with 6 pigs per pen. Diets with flavor were supplemented with the flavor at 1,500 mg/kg in phase 1 diets and 1,000 mg/kg in phase 2 diets. A tendency for a 3-way interaction for ADG from d 5 to 10 (P = 0.10), 10 to 28 (P = 0.09), and 0 to 28 (P = 0.06) was observed. Postweaning ADG of pigs exposed to flavor in creep feed and fed flavored complex diets in the nursery was greater than pigs in any other treatment combination. Increasing diet complexity improved (P < 0.01) ADG and ADFI during both postweaning phases. Adding flavor to creep feed had no effect on G:F (P > 0.34) and pig BW (P > 0.45) in both postweaning periods. Adding flavor to starter diets tended to improve ADFI (P = 0.06) during d 0 to 5. In conclusion, adding flavor to the creep feed did not affect litter creep feed intake, the proportion of piglets consuming creep feed, or preweaning performance when creep was provided for 3 d before weaning. Preweaning exposure to feed flavor improved postweaning ADG in pigs fed complex diets supplemented with the same flavor but did not influence performance of pigs fed simple diets.

“…A adição destes aditivos tem se mostrado de grande importância, principalmente em sistemas com desaleitamento precoce, os quais dependem do consumo de concentrado para serem eficientes e resultarem em bom desempenho. Para animais monogástricos como os suínos já está bem consolidada a eficiência do uso de glutamato e glutamina como palatabilizantes, aminoácidos que também apresentam potencial de melhora da saúde intestinal (WU et al, 1996;GATEL;GUION, 1990;BURRIN, 2001 2009). Em suínos, a inclusão de glutamato na dieta na fase de desmama, período crítico com relação à incidência de diarreia, proporciona aumento no consumo de ração e na taxa de crescimento corporal (GATEL; GUION, 1990).…”

“…Já o glutamato, principal constituinte da proteína da dieta (BURRIN; STOLL, 2009), é o aminoácido intracelular mais abundante, podendo ser utilizado na formação de outros aminoácidos responsáveis pela manutenção e integridade da mucosa intestinal.

Limiting amino acid for the performance of dairy calves: evaluation of optimal levels and feeding routeThe aim in this work was to evaluate the concentration of essential amino acids (Lysine and Methionine) considered in the literature as ideal, according to feeding route (milk replacer or starter concentrate), and its association with the supplementation of glutamate and glutamine to calves in two feeding systems: conventional or step-down. In the first study, the chemical composition was analyzed and in amino acids of main milk replacer marketed in Brazil. In the second and third studies, 45 Holstein calves were used, in randomized blocks distributed in treatments: 1) Control: without supplementation; 2) Supplementation with lysine and methionine to reach consumption of 17 and 5.3 g/d, respectively, with correction based on the analysis basis of the milk replacer, 3) Supplementation of lysine and methionine to reach consumption of 17 and 5.3 g/d, respectively, with correction based on the analysis basis of starter concentrate. The difference between the experiments was the feeding system applied to the calves: in the second study, the animals received 6 L/d of milk replacer; while in the third study, the animals were submitted to the step-down system (4L/d until the 2 nd week; 8L/d of the 3 nd to 6 th week; 4L/d of the 7 th to 8 th week). In the fourth study, the same experimental design was used to evaluate, in a conventional feeding system, treatments: 1) Control: without supplementation; 2) AminoGut 0.6%: milk replacer supplemented with Lysine and Methionine, to reach consumption 17 and 5.3g/d, respectively + 0.6% product containing 10% of glutamate and glutamine; 3) AminoGut 1%: milk replacer supplemented with Lysine and Methionine to reach consumption 17 and 5.3g/d + 0.6% product containing 10% of glutamate and glutamine. The animals were housed in individual hutches, with free access to water and starter concentrate. The consumption of starter concentrate and fecal scores of animals were monitored daily. Body growth was weighed and measured weekly. In weeks 2, 4, 6, 8 and 10, blood samples were collected to determine the metabolites as markers of protein status of animals (albumin, total protein, N-urea), energy status (glucose and BHBA), bone growth (alkaline phosphatase) and muscular growth (creatinine). The composition of amino acids of the milk replacer marketed in Brazil was lower than expected for diet that replaces the whole milk. In study 2 and 3, the supplementation of the milk replacer or starter concentrate with lysine and methionine resulted in no benefit on dairy calves performance or metabolism. In study 4 the supplementation of the milk replacer with lysine and methionine in association with glutamate and glutmine had no effect on performance, gut health nor metabolism of dairy calves.

L-Glutamate (Glu) has traditionally not been considered as a nutrient needed in diets for humans and other animals (including swine) due to the unsubstantiated assumption that animals can synthesize sufficient amounts of Glu to meet their needs. The lack of knowledge about Glu nutrition has contributed to suboptimal efficiency of global livestock production. Over the past 25 years, there has been growing interest in Glu metabolism in the pig, which is an agriculturally important species and also a useful model for studying human biology. Because of analytical advances in its analysis, Glu is now known to be a highly abundant free amino acid in milk and intracellular fluid, a major constituent of food and tissue proteins, and a key regulator of gene expression, cell signaling, and anti-oxidative reactions. Emerging evidence shows that dietary supplementation with 2% Glu maintains gut health and prevents intestinal dysfunction in weanling piglets, while enhancing their growth performance and survival. In addition, the inclusion of 2% Glu is required for dietary arginine to maximize the growth performance and feed efficiency in growing pigs, whereas dietary supplementation with 2% Glu reduces the loss of skeletal muscle mass in endotoxin-challenged pigs. Furthermore, supplementing 2% Glu to a corn- and soybean-meal-based diet promotes milk production by lactating sows. Thus, an adequate amount of dietary Glu as a quantitatively major nutrient is necessary to support maximum growth, development, and production performance of swine. These results also have important implications for improving the nutrition and health of humans and other animals.
