Stunting children need food intake with higher protein and essential amino acids such as lysine and leucine than normal children. Red Beans (Phaseolus Vulgaris L.) and Green Beans (Phaseolus Radiatus L.) have protein content, respectively 22.07 ± 0.13% and 19.99 ± 0.07%, and are rich in essential amino acids lysine and leucine needed by a stunting child. The Development of food products with high protein concentrations (high protein food) such as isolates/protein concentrates is an important subject that must be done. This study aims to determine the technique of isolating red bean and green bean protein through extraction and deposition methods at isoelectric pH. The research method used is an experimental method with descriptive data analysis. Identification of isoelectric pH of red bean and green bean protein is done through electrophoretic mobility (cm2/Vs) testing on samples that have been conditioned at 3 different depositional pHs namely pH 3.00, 4.00, and 5.00. The results showed the isoelectric pH value of red bean and green bean protein, namely pH 4.56 and pH 4.81 respectively, where the pH had electrophoretic mobility values equal to zero. The process of isolating red bean and green bean protein produces protein powder with a protein content of 79.22 ± 0.06% and 80.69 ± 0.06%, respectively. Based on the weight yield, red bean and green bean protein concentrate powder had a yield of 14.88% and 16.75%, respectively.

AbstractIn female mammals, the cessation of ovarian functions is associated with significant metabolic alterations, weight gain, and increased susceptibility to a number of pathologies associated with ageing. The molecular mechanisms triggering these systemic events are unknown because most tissues are responsive to lowered circulating sex steroids. As it has been demonstrated that isoform alpha of the estrogen receptor (ERα) may be activated by both estrogens and amino acids, we test the metabolic effects of a diet enriched in specific amino acids in ovariectomized (OVX) mice. This diet is able to block the OVX-induced weight gain and fat deposition in the liver. The use of liver-specific ERα KO mice demonstrates that the hepatic ERα, through the control of liver lipid metabolism, has a key role in the systemic response to OVX. The study suggests that the liver ERα might be a valuable target for dietary treatments for the post-menopause.

High protein wheat was the sole cereal in 20 and 25 per cent crude protein broiler starter diets. On the. 25 per cent protein diet, performance was maximized without amino acid supplementation. Using high protein wheat in 20 per cent protein diets, growth rate was improved by l-lysine supplementation of 0.3 per cent. However, this growth rate was not at a maximum level. Some other dietary factor was necessary, and this did not appear to be essential amino acids, singly or in combination.

Total Protein Intake

The effect of altering the proportion of dietary protein supplied as essential amino acids (EAA) on the performance and carcass characteristics of young turkeys (to 3 wk of age) was investigated at three dietary protein levels (22, 26 and 30%) using semipurified diets. Four ratios of EAA to nonessential amino acids (NEAA) were employed (70:30, 60:40, 50:50 and 40:60) at each dietary protein level. Maxima in weight gain, percent and total carcass protein and feed intake were observed when EAA supplied 60% of total protein (i.e., the 60:40 ratio) at each protein level. The differences in weight gain and total carcass protein were largely attributed to differences in feed intake, since feed conversion efficiency was relatively unaffected by altering the EAA: NEAA ratio. More specifically, weight gain was shown to be limited by total protein intake. Since weight gain was maximized at the 60:40 ratio diets (in which all EAA are supplied at 128% of requirement) at least one of the EAA requirement values is incorrect.

Low Protein

The aim of the work was to assess the effects of three dietary protein regimes on pig performance and nitrogen (N) excretion, in particular, whether performance can be maintained in lean, fast growing pigs when protein levels are reduced to limit N excretion. Entire male pigs of a lean genotype (Pietrain × Large White × Landrace), 192 in total in four batches, were grown from 40 to 115 kg in pens with four pigs per pen. The diets were: (i) a high-protein control regime; (ii) a low-protein regime in which protein was reduced by ~2 percentage units in each growth stage, but with levels of five essential amino acids the same as in the control (LP1); (iii) an even lower protein regime in which levels of essential amino acids were not maintained beyond 60 kg (LP2). The LP2 regime was designed to promote intramuscular fat deposition rather than efficient growth. Excretion of N was reduced by 17% and 19% in LP1 and LP2, respectively, compared with the control. Average daily gain was lower and feed conversion ratio higher in LP2 than the other regimes, as expected. The control and LP1, which differed in protein but not essential amino acid levels, produced broadly similar results for performance, but pigs in LP1 had poorer feed conversion than control pigs, which could be due to slightly greater fat deposition. The results show the difficulty in maintaining consistently high levels of performance in fast-growing, lean pigs when dietary protein levels are reduced.

Excess Nitrogen

Male broilers were fed diets containing 14, 18 or 22% crude protein (CP) and 10.88, 12.13 or 13.39 MJ kg−1 metabolizable energy (ME) to 3 wk of age. For each level of CP and ME, three diets were formulated so that excess nitrogen arose mainly from nonessential amino acids (NEAA), essential amino acids (EAA) or both. The source of nitrogen excess had no effect on any of the parameters measured in birds fed the 18 and 22% CP diets. However, at 14% CP and over all energy levels, excess nitrogen in the form of EAA gave rise to superior results with regard to weight gain, feed conversion efficiency and carcass protein when compared to those diets where the excess nitrogen arose mainly from NEAA sources. Increasing dietary energy reduced the effect that source of nonessential nitrogen had on weight gain, feed conversion efficiency and carcass protein deposition at 14% CP.

Piglet Survival

Abstract Colostrum intake potentiates piglet survival by transfer of immune factors. Additionally, colostrum also contains nutritional and bioactive molecules which could promote piglet’s growth and development. The objective of this study was to determine the effect of colostrum intake amount during the first 24h on plasma insulin, glucose, protein, and amino acid (AA) concentrations. Two female piglets were selected from 8 litters (n = 16) at birth and fed 10% (COL10) or 20% (COL20) colostrum based on birth weight over 12 bottle feedings occurring every 2h. Colostrum was collected from multiple sows and mixed to create a homogeneous pool. At birth and 24h, blood sample were collected, plasma separated and used to measure insulin, glucose, total protein, and AA concentrations. Analysis of the variance (PROC MIXED, SAS v.9.4) was used to evaluate significant (P≤0.05) differences between colostrum dose and time (birth vs. 24h). Colostrum intake did not influence plasma insulin at 24h (P=0.54). Glucose was higher at 24h (P< 0.001), but did not differ between COL10 and COL20 piglets (P=0.74). Total protein was greater at 24h (P< 0.001) as well as in COL20 compared to COL10 (P=0.006). Non-essential AAs (Ala, Asn, Asp, Cys, Gly and Glu) were reduced at 24h compared to birth (P< 0.03), while essential AAs (His, Ile, Met, Phe, Trp and Val) were increased after 24h of colostrum feeding (P< 0.05). At 24h, COL20 piglets had greater Ile and Met (P< 0.03) and tended (P=0.08) to have greater Leu and Phe. In conclusion, colostrum intake increases glycemia as well as total circulating proteins, and the dose of colostrum is related with greater circulation of total protein and essential AAs.
