Feather wastes represent potential alternative ingredients for animal feedstuffs which can ameliorate the protein shortage for food and feed. Previous attempts to provide information about the nutrient composition of feather meal are either too complicated for rural livestock farmers in developing countries or they provided incomplete information on chemical composition. Washed feathers were subjected to different processing techniques such as pre-soaking in distilled water, wood ash, 0.3M NaOH, a mixture of wood ash and 0.3M NaOH, incubated at 37?C and boiled at 150?C for 60 minutes. Treated feather meals were analysed for chemical composition and amino acid profile. The overall result showed that feather meal pre-soaked with wood ash for 24 hr boiled at 150oC for 60 minutes, those pre-soaked with 0.3M NaOH and wood ash incubated at 37?C for 24 hr boiled at 150?C for 60 minutes and raw feather meal pre-soaked in distilled water for 24 hr boiled at 150?C for 60 minutes gave better results. Wood ash and 0.3M NaOH and their mixture could enhance the nutritional value of feather meal.

Abstract The aim of this study was to evaluate the compositional and nutritional potential of methanolic extracts of various parts of Acacia leucophloea Roxb. concerning the chemical composition and antioxidant potential of which limited information is available. Compositional studies indicated carbohydrates as major components in both seed and pods. Despite differences in mineral content among the leaves, pods and seeds, calcium was found in the highest amount and zinc in the lowest. The amino acid profile indicated aspartic acid as the major amino acid and proline as the minor. Among protein fractions, globulin was present in higher amounts than other fractions. Linoleic acid was the major fatty acid detected in the oil from both pods and seeds, while g-tocopherol was the major component of the tocopherol observed from same oil. Moreover, significant antioxidant potential was observed from the extracts of all three parts investigated. The results obtained in this study clearly indicate that A. leucophloea has a sufficient potential for use as a natural antioxidant agent. Further phytochemical studies will be performed for specification of the biologically active principles.

Ace Inhibitory

Roe has a high protein content and a number of amino acids. The process of removing fat and hydrolyzate with enzymes leads to the breaking of the bonds, so that complex proteins are converted into short chain proteins or peptides and free amino acids. The peptide can act as bioactive and has an effect as antihypertensive, antibacterial, antioxidant and so on. This research was aimed at utilizing processed roes to make hydrolyzate which had previously viewed the chemical composition both fresh and defatted, and to determine the protein profile of the roes from hydrolyzate. The research data were analyzed descriptively,  and the average value and standard deviation were calculated. The results showed that skipjack roes have a fairly complete chemical composition, such as Proximate (protein, fat, moisture, ash, and carbohydrates), with values, respectively 19,19%, 0,67%, 76,32%, 2,51% and 1,31%. It was also found that the dominant amino acid composition of defatted skipjack mature roes is lysine, glutamate and leusine with values, respectively 12.65, 11.20 and 7.72 g/100 g protein and have activity as an angiotensin converting enzyme inhibitory. The ACE inhibitory activity of Skipjack roe hydrolysates of crude papain enzyme from immature and mature value, respectively 36.62% and 38.82%, while pure papain enzyme from immature and mature value respectively 42.63% and 47.54%. The protein profile of the immature roe hydrolyzate range from 10.88 to 125,80 kDA, while the mature roe hydrolysates range from 10.08 to 125,30 kDa.

Soybean is an important source of protein and amino acids for humans and livestock because of its well-balanced amino acid profile. This chapter outlines the strengths and weaknesses of soybean as a complete amino acid source as well as the relative importance of individual amino acids. Special attention is paid to the sulfur-containing amino acids, methionine and cysteine. Breeding and genetic engineering efforts are summarized to highlight previous accomplishments in amino acid improvement and potential avenues for future research. Agronomic properties and processing methods that affect amino acid levels in soybean food and feed are also explained. A brief introduction into current amino acid evaluation techniques is provided. By understanding the complexities of amino acids in soybean, protein quality for humans and livestock can be maximized.

Significant Difference

Waste generation at slaughter from ruminant has led to environmental concerns. Processing slaughter house waste will reduce the problem of disposal and possible utilisation in livestock feed. Subjecting Cattle hoof meal to different processing methods can help in enhancing its nutritive value. Cattle hoof were obtained from the slaughter house; raw hoof was subjected to processing methods by boiling; chemical treatment with 10 % soda ash + boiling; fermentation treatment in water + boiling; 10 % wood ash treatment in water + boiling; autoclave treatment and samples analysed for proximate composition, amino acid profile and mineral content analysis according to standard methods. The hoof proximal analysis ranged 9.30 ± 0.06 % – 12.39 ± 0.01 % moisture content; 0.34 ± 0.01 % – 2.50 ± 0.12 % ash; 0.31 ± 0.01 % – 1.47 ± 0.02 % crude fat; 0.19 ± 0.02 % – 12.71 ± 0.15 % crude fibre and 85.27 ± 0.20 % – 90.74 ± 0.26 % crude protein in all samples. The amino acids profile of the hoof showed significant difference among treated samples. Tryptophan an essential amino acid was below detectable limit in all processed samples and raw hoof. The essential and non-essential minerals content showed significant difference (P < 0.05) among treatments with highest (Mg, Fe, K) in wood ash; (Cu) in raw hoof; (Ca, Na, P, Mn, Zn) in autoclaved samples. This study, suggest that Cattle hoof has the potential of being exploited as a source of animal protein for feed formulation in animal nutrition. This research concludes that the different processing methods affect the nutritive profiles of treated samples hence supplementation of limiting amino acids envisaged.
