E-mail: ahmed.saleh1@agr.kfs.edu.eg Abstract: This study was conducted to examine the effects of a combined supplementation of Aspergillus awamori (AA) and Lactic acid bacteria (LAB) in feed on growth and egg quality. Hens (28 week old) were fed on a basal diet as control group; diets supplemented with 0.05%
Western diet and culture are responsible for the increase of global meat consumption, over the last few decades. This is why the global trend of moving “towards concentrated animal feeding operations is expected
Statistical analysis for the animal studies. Our selection of 10 animals per time point is based on the group variance observed in our preliminary studies employing diet models. For example, an n = 10 provides 95% power (alpha of 0.05) to detect differences in ALT values of at least 30 U/L between two means with a standard deviation of 10 (two-tailed t-test). For endpoints such as ALT values, caspase positive cells, etc., in different animal populations, parametric analysis will be performed. ANOVA will be employed given the presence of multiple groups, and a Bonferroni test will be used to correct for multiple comparisons. If the distribution of values is unsuitable for a parametric analysis, we will perform a Kruskal-Wallis test for nonparametric data. If the data show a strong trend towards significance (e.g., p < 0.1) with reproducible data except for a rare outlier, we can consider increasing the number of animals per group. The number added will be calculated using the mean and standard deviation (SD) from the existing data
The last forty-five years has seen a significant increase in world animal protein production. Since 1967 global production of poultry meat has increased by around 700%, eggs by 350%, pig meat by 290%, sheep and goat meat by 200%, beef and buffalo meat by 180% and milk by 180%. Livestock are increasingly important to the food security of millions of people. (Leyonhjelm 3)
We have all wondered where, and how the poultry that is in our grocery stores had gotten there at some point in time, whether if we eat meat or not. When we find out, we are not too ecstatic with the results. It is unbelievable what they do just in order to get profit from the many variations of chicken the companies produce. They treat the birds as if they are not a living, breathing animal sitting right in front of them. They have no sympathy, for this wonderful creation, and all that it has to offer us. The companies only care about the money, and will do anything to get it. Big chicken industries such as Tyson and Perdue, force farmers to raise their chickens in certain ways, and by doing this, the chickens are raised in unhealthy conditions, which puts consumers’ health at risk.
In a 2012 gallup poll, only 5% of the U.S. is vegetarian and 2% is vegan(Newport). As animal products continue to be consumed, chickens, have enlarged in size over the last couple of decades. An article written on The Washington Post by Roberto A Ferdman said that Americans are eating less red meat, but more white meat. He states,”the obsession with chicken—which has lasted more than 30 years already—shows no sign of stopping”.(Ferdman Para 1). Chickens are being modified to have more mass, more meat, and be bigger in size.
The meat industry today is not what it was nearly a century ago. While improvements are thought to have been made, an ever changing society has brought upon new problems that have been piled on to the previously existing ones. While these problems are not like those found in The Jungle, they do parallel how by exposing what is going on in the meat industry; new regulations would be the answer to the noted problems. The increased demand for meat has made it a rushed mutated production instead of a means to raise livestock for consumers. Taking into consideration the demand for cheap meat that will be used for in quick and high demanded products such as frozen and fast food, this demand of meat has greatly skyrocketed. Animals whose sole
For those who are excited to read about the voyage that leads to the dishes of one of the world deadliest animal that is an American alligator which weighs into several quintals after they are fully grown and again length up to an average of 11 to 13 feet. But apart from all these horrifying figures there are some interesting fact related to alligator meat which convinced Binoy Nazareth to travel all the way to Florida and the facts are as that 100 grams of alligator’s meat (3.2 0z) contain 232 calories, 0 mg cholesterol, 0 g saturated fat, and 4 g of fat and almost 46 g of protein. Moreover, the taste of the alligator’s meat is so much versatile that it can

All that was just listed was the source of authority that these authors have in their country. These authors or professors are well-prepared to write about this topic because they talk about the whole experiment. They inform the reader about what was done in the experiment and what came out of the experiment. This article came from Revista Veterinaria. The intended readers are possibly Buffalo breeders to see what is the best way to feed the calf and what milk is the most nutritious. Also people that are interested in this topic can read this article as well. There
The yolk of eggs contains a compound that kills bateria and reduces inflammation, which is called immunologists.
This trial illustrates that SCFP supplementation in milk (SmartCare) and calf starter (Original XPC) had a positive effect on the health of preweaning calves raised under normal commercial conditions when offered high volumes of milk. The health effects of SCFP stem from reduced FS. Saccharomyces cerevisiae fermentation products can be used to reduce diarrhea in calves grown under normal commercial
Abstract – Yogurt is a product of lactic acid and lactose. In order to produce yogurt, milk is pasteurized (at 45 degrees Celsius) and the inoculum is added followed by incubation. Over a period of 7 days, yoghurt fermentation was attempted using lactobacillus cultures. A liter of milk was supplied and plain yoghurt was used as a starter culture as it contains the necessary bacteria to ferment lactose and produce lactic acid. The milk was added to a flask: then boiled, cooled and inoculated. The milk was incubated for a week and all the while the milk was tested for changes in pH, density, mass and physical changes. The values obtained were then used to determine the growth kinetics of Lactobacillus bulgaricus.
Some benefits can also benefit the product itself. Like many other lactic acid bacteria lactobacillus plantarum229v releases lactic acid if in dairy based product lactic acid might bring a negative side effect of giving it a crude rancid taste and smell in juices with a sour taste like orange, black current, and mango these lactic acid give or enhance the taste. According to a 2006 study of comparison of both probiotic and non-probiotic juice, juices containing lactobacillus plantarum yields a higher mark with emphasis on them being more fragrant and tasteful. Another side effect of these lactic acid is that the lactobacillus plantarum uses the lactic acid to control competing microorganism this affects the product by giving it a longer shelf life without any excessive amount of sugar and or any other added preservative.it is also worth mentioning that by eliminating the need of any preservative production cost can be cut down significantly and the product can now avoid any problems based on the use of
Poultry plays very important role for mankind through food supply, income and employment generation, providing raw materials to some industries, facilitating research works etc. Family poultry makes up to 80 percent of poultry stocks in low-income food-deficit countries (Pym et al., 2006) where owners raise poultry in small numbers ranging from single birds up to a few hundred.
We are required to obtain certain amount of nutrients from food. Food can simply divide into 2 groups, macro-nutrients and micro-nutrients composition. Both of the groups mentioned do affect the metabolism rate. According to Hulbert and Else, dietary fatty acid will affect the metabolism rate and some of the polyunsaturated fatty acid will increase the metabolism rate (1999). Meanwhile, different kinds of animals have their own unique requirement for macro-nutrients, such as proteins, carbohydrates and fat. Moreover, most of the food intake is driven by achieving the required protein intake. Animals on a low protein diet will over eat carbohydrates and fat until the protein requirement has been satisfied. If this case
The main goal for many agricultural producers across the country is to annually improve the quality of their stock. For certain companies such as Cargill and JBS who are two of the largest protein distributors across the globe, an improvement for their stock could be reaching their end point faster. For other operations involved in the purebred or show aspect of the industry improving the quality could mean producing better structured animals who are larger framed.
