This study examined the nutrient profiles, palatability, and intake of three blood sources (current blood, frozen blood, and freeze-dried blood) fed to vampire bats. The nutrient profiles were similar between the blood treatments and included dry matter, organic matter, protein, energy, and various minerals. Microbial plating analysis found some differences in aerobic plate counts between samples but similar levels of other bacteria. The bats consumed significantly more blood in the afternoon than morning, but had no preference between blood treatments. This suggests that various processed blood sources can support captive vampire bats without impacting their nutrition or consumption.

ABSTRACT- Some Lactobacillus species (L. acidophilus, L. casei and L. plantarum) were isolated from locally fermented products (ogi, fura de Nunu and wara) and their effect on microbial infections caused by some pathogenic bacteria (E.coli, K. pneumoniae, Pseudomonas aeruginosa and Staphyloccoccus aureus) isolated from urine and high vaginal swab samples were studied using standard micriobiological methods.Fifiteen (15) healthy guinea pigs used for the study were divided into three (3) groups of five (5) guinea pigs each and placed in three (3) different cages. The pigs were initially fed for two (2) weeks (acclimatization period) with conventional feeds before administering the treatment. Lactobacillus species were introduced into the guinea pigs in cage 2 after the acclimatization period. Subsequently, the guinea pigs in cages 1 and 2 were orally infected with all the clinical bacteria pathogens while the guinea pigs in cage 3 which served as control were left with no microbial treatment. Ten (10) days after treatment, the packed cell volume (PCV), haemoglobin concentration (HBC), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activity level were determined. Striking differences were observed from guinea pigs in the different cages. The effectiveness of Lactobacilli (probiotics) was evident when the guinea pigs in cages 1 and 2 were compared. The guinea pigs in cage 1 which were infected with pathogens but no probiotics had lower blood level (mean PCV= 24.8%) and inferior liver condition (mean ALT=58.18µl; mean AST=51.91µl). Higher blood level (Mean PCV=45%) and superior liver conditions (Mean ALT=9.51µl; mean AST=9.7µl) were obtained for guinea pigs in cage 2 which were infected with the same pathogens and fed with probiotics. The control (cage 3) had the highest PCV level and best liver conditions (mean PCV=46.6%, means ALT= 7.65µl; mean AST=11.83µl).Th .This might be attributed to the fact that they were not infected with pathogenic organisms. Lactobacillus species administered are promising probiotics against the tested bacterial pathogens.

Studies On The Effectiveness of Mixed Diet of Garden Egg, Groundnut And Garli...IOSR Journals
The use of medicinal plants as food supplements and in the treatment of specific diseases dates back to antiquity. Age old anecdotal reports from many cultures strongly suggests a role for diet of plant origin in preventive and therapeutic medicine. Anaemia remains a major public-health problem especially in developing countries. This study aimed at investigating the antianaemic potentials of combined diet of garlic (Allium sativum), garden egg (Solanum melongena) and groundnut (Arachis hypogaea).Twenty five wistar rats of both sexes weighing 160-200g were divided equally into five groups. Group 1 served as the non-anaemic control and fed with normal rat chow. Groups 2, 3, 4 and 5 were induced with anaemia by oral administration of phenylhydrazine (PHZ) given at 50mg/kgBW. Group 2 served as anaemic control, fed with normal rat chow; Group 3 were fed with 20g (75%ww) of garlic, garden egg and groundnut in the ratio of 1:1:1 with normal rat chow; Group 4 fed with 10g of garden egg (50%ww) in the ratio 1:1 with normal rat chow and Group 5 fed with 10g of ground, nut (50%ww) in the ratio 1:1 with normal rat chow. Animals were sacrificed at the end of fourteen days of dietary feeding using chloroform vapour with blood collected at the left ventricle to test for haematological parameters such as red blood cell (RBC) count, white blood cell (WBC) count, hemoglobin concentration (Hb) and packed cell volume (PCV). Results showed that RBC, WBC, Hb and PCV values increased in all the experimental as compared to anaemic control with a significant (P<0.05) in WBC values of groups 3 and 4 as compared to the anaemic control. This suggests a consumption of garlic, garden egg and groundnut will moderately improve anaemic condition.

THE EFFECT OF PROTEIN DIGESTION ON ZEBRAFISH METABOLIC RATE
INTRODUCTION
protein form one of the primary nutrients that are used in the body for cellular structures building (Acheson 525). the process of protein digestion involves the breakdown of food substances we eat into soluble solutions that can be absorbed in the bloodstream. protein is broken down to form amino-acids within the digestive systems and the amino acids are absorbed into the hepatic portal system. the proteins are the building blocks in the body and they include food substances such as eggs, meat, milk as well as beans and nuts among many other food products (Acheson 527). the digestion of proteins mainly begins in the stomach and continues in the small intestine (Acheson 530). digestion of proteins is facilitated by pepsin enzymes that promotes the digestion of the large proteins molecules into amino acids. the digestion of proteins in the body also includes the use of hydrochloric acid (Acheson 526). zebra-fish is preferred in research studies since it is cheap, have similar organs as human beings and produces a lot of offspring. zebra-fish also has a short life-span of about two years and are easy to take care of.
Therefore, the primary objective of this research paper is to evaluate the effects that protein provide on the fish metabolic rate especially after three to four hours.
STATEMENT OF THE PROBLEM
In most cases, protein digestion takes place in both the stomach and in the small intestine in the body of human beings. However, in Zebra fish, protein digestion involves the use of associated organs. the dietary ingredients, and nutrients as well as anti-nutritional remain important factors that affect Zebra fish growth and development. However, there lacks proper nutritional control due to the absence of standardized reference diet (Boyle et al.,2008). Moreover, according to epidemiological studies by Richard et al. (2015), prenatal conditions are important in the growth and development of Zebra fish. As a way of providing a standardized dietary framework, a need emerges for the provision of specific dietary and nutritional standard aimed at improving the growth and development of Zebra fish. Thus, this project aim to evaluate how the level of? protein in commercial fish foods affects the metabolic rate of Zebra fish (Danio rerio).
BACKGROUND
The consumption of proteins could have significant effects on body metabolism. proteins commonly require more calories for breakdown than carbohydrates and this could have significant effects on various metabolic aspects, including an increase in the metabolic rate of organisms (Williams et al., 2014). Due to the strong bond making the protein molecules, a lot of energy is required to break down the high protein that has been consumed. about 30% of the calories in proteins are burned in the process of digesting proteins(Acheson et al. 528). The heat generated in the process increases the general body heat output h ...

IntroductionIntroduction
Vampire Bats have been stereotyped centuries ago. People have been scared and frightened about these
misunderstood creatures, especially when it came to their diet. The Common Vampire Bat’s, Desmodus rotundus, diet is
blood taken from other mammals. Vampire Bats, in the wild, usually inject their two incisors into a larger animal and
consume that animal’s blood by lapping rather than sucking. They have an anticoagulant in their saliva that prevents blood
clots while feeding. Vampire Bats will drink about 40 millimeters (8 teaspoons) of blood a night, which corresponds to about
132% of its body weight (Richarz, 1993). However, captive vampire bats, like the ones at the Henry Doorly Zoo, digest blood
that came from local meat packing facilities. When blood is processed, the amount of dangerous bacteria is may be high as
a result of mishandling. Chaverri (2006) identified thirty different bacteria species in the stomach and intestines of wild
vampire bats. In theory, this may affect the young juvenile vampire bat’s life span. Unfortunately, there isn’t much existing
data regarding to the microbial profiles, preferences, and the nutrition of blood to captive vampire bats.
In order to determine if the captive bats would consume blood processed differently, we fed twelve common vampire
bats blood that was either Freeze-Dried, after being collected from live cattle, frozen after being collected from live cattle or
blood that was collected from slaughtered cattle from local meat packing facility. These blood treatments were all compared
and contrasted between nutrient profiles, palatability, and their intake among the vampire bats. All three blood treatments
were analyzed on dry matter, organic matter, protein and energy at Henry Doorly Zoo nutrition lab. The microbial plates
and minerals were all analyzed from the local Midwest Laboratory.
ObjectivesObjectives
• Determine the nutrient profiles
of the blood treatments
•Determine the Palatability and
intake of the blood treatments
•Determine the bacteria amount
of the blood treatments
Methods and MaterialsMethods and Materials
This study was done at the Henry Doorly Zoo in the nutrition laboratory analyzing data for three different blood treatments. The Vampire Bats were cared for, monitored and
fed by the Henry Doorly Zoo Jungle keeper staff with the supervision of the principal investigator.
• The study was a complete block design consisting of a six 5-day blocks for a total of 30 days
• Two diets were fed out randomly among four ice trays. (One type of blood treatment was in two ice trays, while the other blood treatment was in the other two ice trays)
• The amount of blood fed daily, was split into half. Half of the blood would be fed in the morning, and the other half would be fed in the afternoon.
• The ice trays were rotated and randomized so that the diets weren’t fed in the same location
• There was an evaporation tray that determined any evaporative loss based on light, temperature, and humidity of the exhibit.
Intake of blood from each tray was determined and recorded by accurate weighing of blood offered and refused daily
• The Dry Matter percentage for all of the blood treatments were achieved by the Freeze-Dried percentage 19.4%
• Crucible contained wet samples that were placed into the muffle furnace at 500°C for 24 hours. The organic matter was combusted so that the ash could be weighed back.
• Organic Material’s percentage in the sample could be calculated after the ashing procedure.
• The LECO FP-528 was a machine that determined the percentage of nitrogen in a sample.
• The percentage of protein was calculated by multiplying the percentage of nitrogen by a factor of 6.25.
• Data was entered in a statistical software program called SAS (SAS Institute) in which the data was analyzed using the GLM (General Linear Models) procedure of SAS (SAS
Institute).
• Microbial plating and minerals were all analyzed at the Midwest laboratory located in Omaha, NE.

This data table shows the average blood
consumed per period, the average p-value, the
minimum p-value, and the maximum p-value
when comparing all possible period combinations.
The average p-value was 0.8399. the minimum
p-value was 0.01204, which was associated with
the period 2 vs. 6 combination. Although
numerically the consumption was lower during
period 6 compared with period 2, this difference
did not reach statistical significance of having a p-
value less than 0.05. Based on the statistics,
I conclude that the bats did consume similar
amounts of blood during each of the treatments
regardless of the blood offered to them.

Before my study, there wasn’t much knowledge or research
about the nutritional value of blood fed to Desmodus rotundus and
microbial profiles. My results have shown that captive vampire bats do
not have a preference between the blood treatments: Current Blood,
Frozen Blood, and Freeze – Dried Blood. This is beneficial because zoos
all over the world can now have the chance to house vampire bats in their
domain. There aren’t many zoos that can house vampire bats because
theythey don’t have a meat packing facility near them. Frozen Blood and
Freeze – Dried Blood are more beneficial then the Current Blood for a
variety of reasons. Freeze Dried and Frozen Blood both have the same
nutritional value as the Current Blood.
