Performance and plasma amino acids of growing calves fed corn silage supplemented with ground soybeans, fishmeal and rumen-protected lysine. (1/4)
A 100-d growth study was conducted to evaluate performance and plasma amino acid (AA) responses of 96 crossbred beef calves (220 kg) with ad libitum access to corn silage and supplemented with ground soybeans (GSB) with or without added fishmeal (FM) and (or) rumen-protected lysine (Lys). Calves were allotted by breed, sex and weight to four treatments with three replicate pens of eight calves per pen. The treatments were: GSB, GSB + Lys, GSB + FM and GSB + FM + Lys. The isonitrogenous supplements were top-dressed on corn silage once daily at a level of 2.27 kg/hd, with FM providing one-half of the supplemental N in FM-containing supplements. The Lys-containing supplements provided a daily intake of 6.0 g/hd of rumen-protected Lys. Dry matter intake was similar (P less than .10) for all treatments. Overall ADG and feed efficiency of GSB calves averaged .83 kg/d and 7.39 kg feed/kg gain, respectively, and were 14% lower than the mean of calves fed supplements containing FM and(or) Lys. Lysine was not the principal factor limiting growth because the inclusion of Lys alone in the GSB-containing supplements did not improve (P greater than .10) ADG, feed efficiency or plasma AA concentrations. In contrast, FM supplementation increased (P less than .05) ADG, feed efficiency and plasma concentrations of total AA, total essential AA and total nonessential AA. The inclusion of Lys in the GSB + FM-containing supplement resulted in no further improvement (P greater than .10) in performance.(ABSTRACT TRUNCATED AT 250 WORDS) (+info)Availability of selenium in fish meal in comparison with soybean meal, corn gluten meal and selenomethionine relative to selenium in sodiumselenite for restoring glutathione peroxidase activity in selenium-depleted chicks. (2/4)
We assayed the availability of selenium in feeds and selenomethionine relative to selenium in sodium selenite for restoring blood serum glutathione peroxidase activity in selenium-depleted chicks. The contents of total selenium (determined by neutron activation analyses) were for eight samples of capelin fish meal, 1.34, two samples of mackerel fish meal, 6.17, one sample of solvent-extracted soybean meal, 0.42, and one sample of corn gluten meal, 0.54 ppm in dry matter. The availability of the selenium (relative to selenium in selenite=100%) in capelin fish meal was 48.0 (38.5--60.0), mackerel fish meal, 34.1 (32.3--35.8), soybean meal, 17.5, corn gluten meal, 25.7, and in selenomethionine, 78.3%. (+info)Effects of dietary proteins from a variety of sources on plasma lipids and lipoproteins of rats. (3/4)
Five experiments were conducted to study the effect of various protein sources on fasting blood lipids and lipoproteins in the rat. Plasma levels of total cholesterol, high density lipoprotein (HDL)-cholesterol and total triglyceride, as well as weight gain, food intake protein efficiency ratio and net protein utilization were measured over 28-day test periods with male Sprague-Dawley rats. The purified proteins studied included casein, egg albumin, lactalbumin, soy and alfalfa. Crude proteins studied included yeast, fish meal and blood meal. Diets low in methionine were supplemented with this amino acid to insure that all diets were nutritionally adequate. Although the plasma total cholesterol levels varied by 40-50% and HDL-cholesterol by 90% among the various diets, the changes were not associated with any particular dietary protein source or level. Plasma total triglyceride levels varied independently of the dietary source and level of protein. Plasma HDL-cholesterol accounted for approximately 70% of the plasma total cholesterol. Plasma HDL-cholesterol concentrations correlated positively (R = 0.72) with plasma total cholesterol and negatively (R = -0.34) with plasma triglyceride levels. These results clearly show that the pure and crude plant proteins did not have a hypocholesterolemic effect compared with pure and crude animal proteins in rats. Plasma HDL-cholesterol levels were the same in rats fed plant and animal proteins. (+info)A biological assay for determination of availability of selenium for restoring blood plasma gluthathione peroxidase activity in selenium-depleted chicks. (4/4)
This study was undertaken to develop an assay for the determination of biological availability of selenium. In a preliminary experiment, commercial male, White Leghorn chicks had significantly reduced glutathione peroxidase activity in blood plasma after 7 days of depletion on a selenium-deficient (0.04 ppm of Se) diet. Selenium-depleted chicks fed graded levels of selenium (0.02--0.10 ppm in steps of 0.02 ppm) for 9 days had glutathione peroxidase activity in blood plasma which was linearly, highly correlated with dietary selenium content. In three subsequent experiments, chicks were fed a selenium-deficient diet for 7 days and were then distributed into groups of five chicks each. The standard diets, which contained 0.02, 0.04, 0.06, 0.08 and 0.10 ppm of selenium added as NaHSeO3, and the test diets, which contained three levels of each test substance and provided selenium supplements within the standard range, were each fed to three groups of chicks for 9 days. The dose parameter was selenium, in the standard groups added as NaHSeO3 and in the test groups provided by the selenium present in the test substance. The response parameter was blood plasma glutathione peroxidase activity. Statistical analyses of the results utilizing four fish meals as test substances revealed that the assay complied with the requirements for statistical and fundamental validity. (+info)I'm sorry for any confusion, but "Fish Flour" is not a recognized term in medical terminology. It is possible that you may be referring to "fish meal," which is a product made from ground-up fish and is used as a protein source in animal feeds. However, it is not typically used in human food or medicine. If you have any concerns about the use of this substance or any other unusual substances in human health, I would recommend consulting with a healthcare professional for accurate information.
I believe there may be a misunderstanding in your question. The term "fishes" is not typically used in a medical context. "Fish" or "fishes" refers to any aquatic organism belonging to the taxonomic class Actinopterygii (bony fish), Chondrichthyes (sharks and rays), or Agnatha (jawless fish).
However, if you are referring to a condition related to fish or consuming fish, there is a medical issue called scombroid fish poisoning. It's a foodborne illness caused by eating spoiled or improperly stored fish from the Scombridae family, which includes tuna, mackerel, and bonito, among others. The bacteria present in these fish can produce histamine, which can cause symptoms like skin flushing, headache, diarrhea, and itchy rash. But again, this is not related to the term "fishes" itself but rather a condition associated with consuming certain types of fish.
"Fish diseases" is a broad term that refers to various health conditions and infections affecting fish populations in aquaculture, ornamental fish tanks, or wild aquatic environments. These diseases can be caused by bacteria, viruses, fungi, parasites, or environmental factors such as water quality, temperature, and stress.
Some common examples of fish diseases include:
1. Bacterial diseases: Examples include furunculosis (caused by Aeromonas salmonicida), columnaris disease (caused by Flavobacterium columnare), and enteric septicemia of catfish (caused by Edwardsiella ictaluri).
2. Viral diseases: Examples include infectious pancreatic necrosis virus (IPNV) in salmonids, viral hemorrhagic septicemia virus (VHSV), and koi herpesvirus (KHV).
3. Fungal diseases: Examples include saprolegniasis (caused by Saprolegnia spp.) and cotton wool disease (caused by Aphanomyces spp.).
4. Parasitic diseases: Examples include ichthyophthirius multifiliis (Ich), costia, trichodina, and various worm infestations such as anchor worms (Lernaea spp.) and tapeworms (Diphyllobothrium spp.).
5. Environmental diseases: These are caused by poor water quality, temperature stress, or other environmental factors that weaken the fish's immune system and make them more susceptible to infections. Examples include osmoregulatory disorders, ammonia toxicity, and low dissolved oxygen levels.
It is essential to diagnose and treat fish diseases promptly to prevent their spread among fish populations and maintain healthy aquatic ecosystems. Preventative measures such as proper sanitation, water quality management, biosecurity practices, and vaccination can help reduce the risk of fish diseases in both farmed and ornamental fish settings.
Fish oils are a type of fat or lipid derived from the tissues of oily fish. They are a rich source of omega-3 fatty acids, specifically eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These fatty acids have been associated with various health benefits such as reducing inflammation, decreasing the risk of heart disease, improving brain function, and promoting eye health. Fish oils can be consumed through diet or taken as a dietary supplement in the form of capsules or liquid. It is important to note that while fish oils have potential health benefits, they should not replace a balanced diet and medical advice should be sought before starting any supplementation.
