The objectives of the experiment were:1.To assess the suitability of antigen-free soya protein concentrate (SPC) and whey products as major ingredients and the sole protein source in milk substitute diets for calves.2.To compare the effects of inclusion rates of 0, 350 and 700 g protein from SPC/kg dietary protein.3.To investigate the suitability of introducing these diets to calves at 2 or at 16 days of age.A fat-filled whey based milk substitute (diet WP1) was compared with similar diets in which SPC provided 350 g/kg protein (diet SK1J or 700 g/kg protein (diet SK2). Thirty-six Friesian bull calves were given one of these three diets reconstituted in water (1 powder:6 water w/w), offered at 38°C by bucket to appetite in two feeds daily, either at 2 days of age or after a 14-day period in which they were given a skim-based milk substitute (diet WP4).

Processed fruit products commonly contain very low protein due to the heat treatment during processing period. This article presents the researchresults concerning the increase of nutrition value of papaya jam fortified with soya protein concentrate. Papaya jam prepared with ratio 40:1, 40:2, 40:3, 40:4, and 40:5 (v/v) of papaya pulp and soya protein concentrate. The treatment of papaya jam and soya protein with the highest acceptability was then analyzed for the changes in chemical constituents and overall acceptability at monthly interval during three months of storage. The parameters that being analyzed were moisture content, total soluble solids (TSS), pH, total and reducing sugars, non-enzymatic browning, acidity, ascorbic acid, total carotenoid, total phenol, crude protein, and total plate count.  The results showed that fortified papaya jams prepared with papaya pulp and soy protein concentrate ratio at 40:1 had the highest acceptability. During storage time it revealed that moisture content, TSS, pH, total and reducing sugars, and non-enzymatic browning increased, while acidity, ascorbic acid, total carotenoids, phenols, total antioxidants and crude protein contents of jam decreased. Fortification of papaya jam with soya protein concentrate (40:1 v/v) increased crude protein content on average from 3.15% to 4.16%. Total plate count (TPC) indicated that no microbial contamination during 3 months storage period. It can be concluded that papaya jam fortified with soya protein concentrate remained acceptable during storage although the acceptability decreased over time.

Obese Zucker Rats

Casein-based diets containing a low (LDI) or high (HDI) dose of soya protein concentrate enriched with isoflavones were fed to obese Zucker rats for 6 weeks. HDI feeding, but not LDI feeding, reduced the fatty liver and decreased the plasma levels of alanine transaminase and aspartate transaminase. This was accompanied by increased activities of mitochondrial and peroxisomal β-oxidation, acetyl-CoA carboxylase, fatty acid synthase and glycerol-3-phosphate acyltransferase in liver and increased triacylglycerol level in plasma. The decreased fatty liver and the increased plasma triacylglycerol level appeared not to be caused by an increased secretion of VLDL, as HDI decreased the hepatic mRNA levels of apo B and arylacetamide deacetylase. However, the gene expression of VLDL receptor was markedly decreased in liver, but unchanged in epididymal white adipose tissue and skeletal muscle of rats fed HDI, indicating that the liver may be the key organ for the reduced clearance of triacylglycerol-rich lipoproteins from plasma after HDI feeding. The n−3/n−6, 20:4n-/8:2n−6 and (20:5n−3+22:6n−3)/18:3n−3 ratios were increased in liver triacylglycerol by HDI. The phospholipids in liver of rats fed HDI contained a low level of 20:4n−6 and a high level of 20:5n−3, favouring the production of anti-inflammatory eicosanoids. When obese Zucker rats were fed soya protein, this also resulted in reduced fatty liver, possibly through reduced clearance of VLDL by the liver. We conclude that the isoflavone-enriched soya concentrate as well as soya protein may be promising dietary supplements for treatment of non-alcoholic fatty liver.

1. Five proteins, freeze-dried cod muscle, a white fish meal, a yeast-protein concentrate, a soya protein and a fish-protein concentrate (a solvent-extracted fish meal) were given separately, as single sources of protein in diets containing 500g crude protein/kg, to small plaice (Pleuronectes platessa) of mean initial weight 12–15g. Weight gain and net protein utilization (NPU) were examined.2. Even at these high protein intakes, significant differences in growth rate between fish given the different proteins were evident. These findings were reflected in different NPU values between the proteins. This position contrasts with that in the rat where proteins which differ markedly in NPU at low protein intakes have similar NPU values when given at high dietary levels.3. Coefficients of apparent digestibility measured on larger plaice (150–200g) were high for all the proteins used except soya-bean meal, which had a digestibility coefficient of 0.68.4. At high protein intakes there was no clear relationship between NPU values and essential amino acid content (as measured chemically) of the proteins tested.5. The preparation of protein concentrates from fatty fish by the use of detergents is described. One of the preparations obtained gave weight gains and NPU values similar to those obtained with commercially available feedstuff proteins.

ABSTRACT       The addition of atractant in feed is expected could improve snakehead respond,andincreasing its growth. The Aims of this study are to knowfeed respond, the feed intake, growth, feed efficiency, and survival rate of snakehead fry given by feed with different various of atractant.This research was conducted on Jun-July 2016 at Laboratorium Dasar Perikanan Program Study Budidaya Perairan, Agriculture Faculty, Sriwijaya University. This research was using completely randomized designed with four treatments and three replications, consist offeed without attractants (P0), feed with 2% fish meal addition (P1), feed with 2% squid meal addition (P2), and feed with 2% shrimp meal addition (P3). Fish maintained for 30 days and fed four times a day (at 07.00, 11.00, 14.00 and 17.00) are at satiation. Parameters of this research are feed respond, the feed intake, growth, feed efficiency and survival rate of snakehead fry. The result showed that given of atractant effect to feed intake and absolute growth of weight (Channa striata) fry, yet did not give effect to snakehead respond significantly, for absolute growth of length, feed efficency and survival rate.

Alfalfa Meal

Corn and soybean meal are the two main components in formula feed of farm animals, leading to a serious food competition between humans and livestock. An alternative may be to encourage the utilization of unconventional feedstuff in animal diet. In the current study, we evaluated the utilization of fermented alfalfa meal (FAM) in weaned pigs. Twenty weaned piglets (separately caged) were randomly divided into two groups. Pigs in the control group (CON) were fed corn-soybean meal diet, and part of corn and soya protein concentrate in the diet of another group was replaced by 8% FAM. After 40 days of feeding, the average feed intake of FAM pigs was increased (P > 0.05), and the villus height (VH) of jejunum and duodenum, crypt depth (CD), and VH/CD in FAM pigs was improved compared to the CON group (P < 0.05). The increase (P < 0.05) of goblet cells in the jejunum of FAM pigs was positively correlated with the expression of MUC-2 gene (R = 0.9150). The expression of genes related to immunity (IRAK4, NF-κB, and IL-10) and intestinal barrier (Occludin and MUC-2) in the jejunum, as well as the expression of ZO-1 and MUC-2 in the colon of these pigs, also showed increase (P < 0.05) compared to CON pigs, which was accompanied by the decrease (P < 0.05) of LPS concentration in the serum. The elevated proportion of CD3+ and CD8+ T-lymphocyte subsets in spleen (P < 0.05) confirmed the improvement of systemic immune function in FAM pigs. In addition, FAM pigs have a higher β-diversity of microbial community (P < 0.05) and promoted enrichment of probiotics such as Lactobacillus that positively was correlated with acetate concentration in the colon over CON pigs. In summary, partially replacement of expanded corn and soya protein concentrate with FAM (8%) may benefit the intestinal barrier and immune function of weaned pigs without affecting their growth. Our findings also provide evidence of the feasibility of FAM as a dietary component in pigs to reduce the consumption of grain.
