Providing bees with benign and sufficient protein feeds is the key to successful beekeeping. Protein feed significantly affects on certain functions of individuals and the vital activity and productivity of the bee colonies. So, as a result of increased consumption of protein feed during the first days of life the supply of proteins in the body significantly increases in young bees, hypopharyngeal glands and other organs become developed, which provides the ability to perform various tasks depending on age and living conditions. Older bees consume protein for tissue renewal with new cells and metabolic processes. Bees raised on low protein feeds become physiologically defective and do not live long. In conditions of protein starvation, brood rearing stops and bees throw larvae out of their cells. The article presents the results of studying the effect of using soy flour and its processed products in bee feeding on the essential amino acids content in their body. It was found that the use of soy peptone in bee feeding contributes to a greater accumulation of essential amino acids in the bees body in different periods of their development, in compared to soy milk, defatted soy flour and roasted soy flour which indicates a higher efficiency of its use as partial substitutes for protein feeds.

Pullets were brought into production on a low-protein corn, soybean meal diet to which various nutrients including essential amino acids, choline, corn oil and feathermeal were supplemented. Production commenced between 18 and 20 wk of age and up to at least 60% production, hens fed the low protein diets (10% CP) produced at least as many eggs and as great an egg mass as these given a 17% protein corn, soybean meal control diet. Pullets fed the corn, soybean meal test diets, peaked at around 80% as compared to slightly over 90% for the control. Egg production immediately fell for birds fed the test diets to around 70% for most of the test treatments. Body weight remained constant or fell after peak production for birds fed the test diets as compared to a normal increase for birds on the control diet. Egg size increased for the test diets at a rate which was comparable to that of the control birds. In a second experiment, with older hens, supplementation of the 10% protein test diet with methionine, lysine, arginine and tryptophan, resulted in intakes of these amino acids which met NRC minimum requirement levels. However, egg mass output was reduced approximately 11% compared to the 17% protein control diet. While intakes of several essential amino acids fell below requirement levels, the degree that valine was calculated to be deficient in both experiments corresponded closely with the reduction in egg mass output of hens fed the test as compared to the control diet. Key words: Lysine, methionine, egg weight, body weight, hens.

                                                                   AbstrakAsam amino adalah komponen terkecil yang menyusun protein. Sejumlah asam amino akan dihubungkan satu sama lain melalui perantara ikatan peptida untuk membentuk protein. Asam amino telah dibagi menjadi dua; yaitu asam amino esensial dan asam amino non-esensial. Asam amino esensial adalah asam amino yang tidak dapat disintesis oleh tubuh ikan; karena itu asam amino esensial harus ada dalam pakan. Lisin adalah salah satu dari sepuluh asam amino esensial, fungsi lisin adalah untuk pertumbuhan dan perbaikan jaringan tubuh. Penelitian ini bertujuan untuk mengetahui pengaruh lisin dalam pakan komersial terhadap retensi protein dan retensi energi ikan bawal air tawar. Metode yang digunakan adalah desain eksperimen rancangan acak lengkap. Perlakuan yang digunakan adalah kadar lisin yang berbeda, yaitu P0 (0%), P1 (0,6%), P2 (1,2%), P3 (2,4%), P4 (4,8%) dan perlakuan  diulang 4 kali. Parameter utama yang diamati adalah retensi protein dan retensi energi pada air tawar bawal. Parameter yang diukur didukung oleh parameter kualitas air. Analisis data menggunakan Analisis Varian (ANOVA) dan untuk menentukan perlakuan terbaik digunakan Duncan's multiple range test. Hasil penelitian menunjukkan perbedaan yang signifikan (p <0,05) dalam retensi protein dan energi adalah daging ikan bawal air tawar. Retensi protein dan retensi energi dalam pengobatan P1 (0,6% lisin), P2 (1,2% lisin), P3 (2,4% lisin) dan P4 (4,8% lisin) berbeda secara signifikan dengan perlakuan P0 (kontrol). Kualitas air selama 40 hari perlakuan ditetapkan pada suhu 27-300 C, pH 7,5-8,5, amonia 4 mg / l dan oksigen terlarut 4 mg / l.                                                                 AbstractAmino acids are the smallest components that compose proteins. A number of amino acids will be conducted to one another through the intermediary of peptide bonds to form proteins. Amino acids have divided into two; those are essential amino acids and non-essential amino acids. The essential amino acids are amino acids that can not be synthesized by the body of fish; therefore the essential amino acids must be in feed. Lysine is one of the ten essentials amino acids , the function of lysine are for the growth and repair body tissues. This research was aimed to determine the effect of lysine in commercial feed on protein retention and energy retention of freshwater Bawal.The method used is experiment with a completely randomized design as an experimental design. The treatment used is different lysine levels , namely P0 ( 0 % ) , P1 ( 0.6 % ) , P2 ( 1.2 % ) , P3 ( 2.4 % ) , P4 (4.8 % ) and treatment was repeated 4 times. The main parameters were observed protein retention and energy retention on Bawal fresh water. Parameters measured were supported by water quality parameters. Analysis of the data using Analysis of Varian ( ANOVA ) and to determine the best treatment used Duncan 's multiple range test. The results showed the significant differences ( p < 0.05 ) in protein retention and energy were freshwater pomfret fish meat. Retention of protein and energy retention in treatment P1 ( 0.6 % lysine ) , P2 ( 1.2 % lysine ) , P3 ( 2.4 % lysine ) and P4 ( 4.8 % lysine ) was significantly different with treatment P0 ( control ). The quality of water for 40 days treatment was set to temperature 27-300 C, pH 7.5-8.5, ammonia 4 mg/l and dissolved oxygen 4 mg/l.

1. Free amino acid concentrations in the plasma have been compared with those in liver and quadriceps muscle, in rats fed on diets containing 209 (control) and 31 (low-protein) g protein/kg. The effects of the low-protein diet on diurnal variations in these values were also measured.2. In the plasma, the total amino acid concentration was significantly lower in animals given the low-protein diet, at all times of day except 12.00 hours. In the liver, and to a lesser extent the muscle, total amino acid concentration was maintained.3. In the control animals, diurnal variation in the concentrations of both essential and non-essential amino acids was very similar in plasma, liver and muscle. In animals given the low-protein diet, although the same diurnal pattern was maintained for non-essential amino acids, that occurring among the essential amino acids had virtually disappeared.4. In plasma, the mean 24 h concentration of essential amino acids decreased from 24· mmol/l in control animals to only 1·29 mmol/l in the low-protein-fed animals. Concentrations in muscle and liver were reduced by a similar proportion (from 8·6 to 5·56 μmol/g and from 8·67 to 5·05 μmol/g respectively). Conversely the concentrations of non-essential amino acids in animals given the low-protein diet were increased in plasma (from 1·53 to 2·00 mmol/l), muscle (from 12·5 to 14·3 μmol/g), and liver (from 16·8 to 20·5 μmol/g), muscle showing the lowest increase.5. With the exceptions of lysine, threonine, cystine and tyrosine, the concentrations of all other essential amino acids were reduced more in liver than in muscle. The relationship between this and the failure to maintain plasma albumin concentrations is discussed.

Effect Of Feeding

1. A study has been made of the effect of feeding growing rats for a long time on a low-protein, high-carbohydrate diet given at two different levels of energy. 2. When the proteins of the diet provided o or 5% of the calories the body-weight fell rapidly and fat accumulated in the liver. Addition of carbohydrate (glucose) to the diets increased the amount of fat in the liver. 3. It is suggested that a deficiency of protein retards the synthesis in the liver of lipoproteins required for removal of triglyceride from the liver. Additional carbohydrate diverts amino acids from the amino acid pool to tissues such as muscles, increasing the liver damage.

Protein Reduction

Abstract Feeding growing pigs with diets providing the required amount of essential and non-essential amino acids (AA) reduces energy expenditure and minimizes N excretion. Low protein diets can be obtained by supplementing feeds with crystalline AA. Numerous experiments have evaluated the ideal dietary AA concentration at different growth stages, but reducing dietary protein with the use of supplemental AA is limited by the inaccuracy of the principles used to estimate AA requirements. One of these principles states that growing animals need AA for maintenance and growth. Maintenance requirements are related to BW whereas the efficiency of AA utilization (e.g., 72% for Lys) and body protein AA composition are constant (e.g., 7% for Lys). These parameters are, however, affected by AA restriction, meal frequency, energy supply, genetics, etc. Even when controlling these factors, individual pigs respond differently to the same AA supply. Yet pigs are raised in groups and fed with a unique feed for long periods. Individual pigs within a given population differ in terms of BW, ADG, health status, etc., and consequently, differ in the amount of AA they need at a given time. Therefore, when feeding a group of pigs, the concept of maintenance and growth requirements may not be appropriate. In this situation, nutrient requirements should be seen as the optimal balance between the proportion of animals that needs to be overfed and underfed. Given that for most AA, underfed animals exhibit reduced performance, whereas overfed animals exhibit near-optimal performance, optimal growth is obtained when nutrients are provided to satisfy the requirements of the most demanding animals. There is therefore a trade-off between performance and dietary protein reduction. The inaccuracy of the principles used to estimate AA requirements, both for individual animals and populations, limits how far we can go reducing dietary protein with the use of supplemental AA.

Limiting Amino Acid

AbstractThe optimum pattern and limiting order of some essential amino acids for growing-furring blue foxes were assessed from nitrogen (N) retention responses. Total tract digestibility and N balance trials were carried out on 24 weaned blue fox males in an 8 ✕ 5 cyclic change-over experiment. Eight experimental diets were prepared by removing proportionately about 0·4 of each of the amino acids studied – methionine + cystine, lysine, threonine, tryptophan and histidine – successively from the amino acid control diet. The main source of protein in the amino acid control diet was casein and an amino acid mixture was added to bring the calculated crude protein (CP) content up to the level of 170 g/kg dry matter (DM). Low-protein (CP 95·7 g/kg DM) and high-protein (CP 166·6 g/kg DM) diets, the protein proportion of which was casein protein, served as negative and positive control diets, respectively. The reduction in N retention when one amino acid in turn was deleted from the amino acid control diet was calculated, and a regression analysis was made between N retention and relative amino acid intake. Data on the animals’ intake of each limiting amino acid and those on the amino acid control diet were used. The optimum amino acid pattern, expressed relative to lysine = 100, proved to be: methionine + cystine 77, threonine 64, histidine 55 and tryptophan 22. The first-limiting amino acids were methionine + cystine. Blue fox responses (N retention, weight gain) to deletion of methionine + cystine from the diet were very severe and exceeded those to deletion of any other amino acid. Moreover, removing methionine + cystine from the diet significantly impaired the apparent digestibility of organic matter, reducing it to a level even lower than that of the low-protein diet. After methionine + cystine, the next-limiting amino acid in casein-based diets was threonine, followed by histidine and tryptophan. The results show the importance of verifying the sufficiency of dietary methionine + cystine in the practical feeding of blue foxes.
