Meat Animal

<p><strong></strong>The production of meat for human consumption is one of the important items in the economy of a country. This activity has great socio economic importance as it serves as a basis for development, employment generation and sustainability of a country. The demand for animal protein is one of the most precious and necessary factors to maintain a proper biological development of human beings in active growth as well as being a source of growth and tissue regeneration. Consumption has increased because populations continue to grow and there is continuous migration to the cities, which makes the offer insufficient, and therefore it is necessary to accelerate, introduce technology and improve the meat production process. Industry also seeks a reduction in production costs by producers in this sector of the economy, leading to the use and incorporation of technology and cutting-edge knowledge to improve yield production of meat. Such knowledge comprises the scientific basis of the use of growth hormones and promoters (anabolic steroids and others) to accelerate and increase the production of meat. Although there has been an increase in production, residual substances can remain in the meat intended for human consumption which can lead to changes in the health of consumers.</p> <p><strong>Key words</strong>: growth promoter, meat, animal production</p><br />

Selective breeding and improved nutritional management over the past 20–30 years has resulted in dramatic improvements in growth efficiency for pigs and poultry, particularly lean tissue growth. However, this has been achieved using high-quality feed ingredients, such as wheat and soya that are also used for human consumption and more recently biofuels production. Ruminants on the other hand are less efficient, but are normally fed poorer quality ingredients that cannot be digested by human subjects, such as grass or silage. The challenges therefore are to: (i) maintain the current efficiency of growth of pigs and poultry, but using more ingredients not needed to feed the increasing human population or for the production of biofuels; (ii) improve the efficiency of growth in ruminants; (iii) at the same time produce animal products (meat, milk and eggs) of equal or improved quality. This review will describe the use of: (a) enzyme additives for animal feeds, to improve feed digestibility; (b) known growth promoting agents, such as growth hormone, β-agonists and anabolic steroids, currently banned in the European Union but used in other parts of the world; (c) recent transcriptomic studies into molecular mechanisms for improved growth efficiency via low residual feed intake. In doing so, the use of genetic manipulation in animals will also be discussed.

Boldenone (androsta-1,4-dien-17-ol-3-one), an androgenic anabolic steroid (AAS), is intensively used for growth promoting purposes in animals for meat production and as a performance enhancer in athletics. Its use is prohibited either in animals intended for human consumption or directly for humans, as most of the anabolic steroids are completely metabolized. The current method of detection, such as the mass spectrometry coupled with gas chromatography or liquid chromatography are sensitive, highly specific and are popular methods of detection. However, these have some intrinsic drawbacks such as the requirements of complicated and expensive instrumentation, time consuming and production of narrow detection limits. Boldenone and its metabolites in urine samples of animal matrices can be detected by means of electrochemical methods using tunable and chemically-modified screen-printed carbon electrodes (SPCEs).

This study was aimed at assessing marketing efficiency in the main sites of meat production of calf fattening fields in the private sector due to the importance of meat, especially red meat, which has essential nutrient for human body growth and high commodity prices depending on the measurement indicators used to suit the nature of the research conducted in calves fattening production fields in Gogjali region- Nineveh  (2018). The basic source data of the study is obtained from sources on the ongoing ground- marketing questionnaire of three levels, the producer, the wholesaler, the retailer and two fields groups of caste random sample. The first group included (100) fields with imported calves class. The second included (51) fields with local calves class. Whereas, according to the production and marketing costs indicator, the average of marketing efficiency (ME1 ) of marketed meat in both groups of claves fattening fields amounted (92.47, 93.39%) respectively for a kilogram which is a sign of high production costs and, according to the marketing margins indicator, the average of marketing efficiency (ME2 ) of marketed meat in both groups of claves fattening fields amounted (86.89,79.13 %) for per kg which is a sign of high marketing margins. Thus the study concluded a high value of marketing efficiency using the first scale with the fattening period time for both groups while marketing efficiency by using the second scale was characterized by the gradual decline in the imported fattening fields and a gradual rise in the local fattening fields.  The study recommends supporting production inputs (fodder, treatment), unifying markets and limiting the    importation of red meat importation  in order to obtain a good production and currency policy by which the production costs could be reduced to the minimum .

Covid-19 is not just a virus which is risking human lives everyday, but it is a phenomenon which has inflicted major changes on the long-term global survival and economic strategies. The pandemic has brought about major diversions in the world order, which philosophers and scientists have predicted to occur once in a century’s time. Covid-19 has also affected the personal health, physical and psychological of all human beings. It has forced people to change their social behaviors significantly, which has had consequential effect on their mental health. One significant result of the pandemic is the increased consumption of alcohol and other psychoactive substances among people. As people are forced to lock themselves up inside their homes, some have resorted to exercising, biking, running, and meditation to maintain sanity, while others have boosted their addictive behavior by consuming more alcohol and drugs to make staying-indoors more entertaining. Nielsen has reported a 54% rise in the national consumption of alcohol on the week of March 21st 2020, as compared to the same in 2019. The online sales of alcohol have also risen enormously from 2019 to 2020. The study aims to address the problem of increased alcoholism and substance abuse during Covid-19 by understanding the causes of this rise. The method is based on analysis and comparison of available survey reports, to find out exactly what amount of human consumption has increased during the pandemic. From the findings we can conclude that alcoholism and substance abuse has risen significantly during Covid-19, and psychological distress, anxiety and depression can be some major causes for this abnormal social behavior. It can also be implied that this increased alcoholism is likely to affect the physical health, neural and social behavior, and the work life of many human beings through the pandemic.

Abstract. There are two types of Japanese quails, reared in Europe – dual-purpose and meat. The aim of the present study was to made an economic analysis of fattening quails from the dual-purpose and heavy production types. Three groups were formed – group 1 (dual-purpose), groups 2 and 3 (heavy type), reared in cages. After quails sexing on the 16th day of age, there were formed six subgroups: 1m, 1f, 2m, 2f, 3m and 3f. Fattening period lasted until 35 days of age. For revenues calculation produced meat and edible offal data per m2, were used. Costs calculation include consumed feed for the period, day-old quail, and other costs. The main production costs were associated with feed and day-old quails: from 80.3 and 82.6% of all costs in the studied groups. The anticipated revenues from produce in group 2 were 10 EUR/m2 higher than those in group 1, and for group 3 – 10.21 EUR/m2 higher than group А. The results indicate that meat type quails fattening is the most economically efficient in quail meat production. Producing quail edible offal is still not developed but could be beneficial for efficiency of quail fattening small farms.

ABSTRACT: This study evaluated the effect of the three inulin levels (0.1%, 0.2%, 0.4%) supplemented as a substitute for an antibiotic growth promoter (AGP, zinc bacitracin) and control in guinea pigs raised for human consumption. Fifty 14-day-old male guinea pigs were used. Productive parameters (weight gain, total dry matter intake, and feed conversion ratio (FCR)) and intestinal morphology of the duodenum, jejunum, and ileum at slaughter (70 days of age) were evaluated. An inverse relationship was observed between inulin levels and FCR (linear effect; P = 0.006). There was no statistically significant effect of the treatments on total dry matter intake and weight gain (P > 0.05). A linear effect of the inulin level on the villi’s length (VL), villi’s width (VW), and length/depth ratio (VL/DC) in the duodenum; VW in the jejunum; and VL in the ileum (P <0 .05) was reported. In conclusion, a linear effect of the increasing doses of inulin was found on the FCR and the morphological parameters of the duodenum’s integrity, and no differences in the effects of the inulin added to the diet and the treatment with AGP were found.

Identification And Characterization

Natural insecticides now-a-days have a bright future because synthetic insectides are harmful to human beings. Among botanical pesticides, the rotenoids standout for their potency and effectiveness against many crop pests and are fifteen times more toxic than the nicotinic acid. Cajanus cajan primarily grown as a grain crop for human consumption (pulse, vegetable) and has not been analysed for it’s rotenoidal content. Chromatographic analysis showed the presence of four rotenoids namely elliptone, deguelin, rotenone and tephrosin, which were identified by co-tlc, melting point, GLC and IR spectral studies with that of the standard reference compounds. In the present investigation, rotenone (0.37 mg/gdw) was found in maximum quantity which was followed by deguelin (0.27 mg/gdw), tephrosin (0.21 mg/gdw) and elliptone (0.15 mg/gdw).

Important Criterion

The use of probiotics, as fodder supplement for chickens, could stimulate meat quality that is a very important criterion especially for human consumption markets. The study had in view the effects of powdery YEA-SACC 1026 probiotic on meat quality in chicken broilers. There were studied 75 meat chickens of Ross-308 hybrid grouped on three lots of 25 capita/lot during an experimental period of 42 days. In the mixed fodder of experimental lots was added powdery YEA-SACC 1026 probiotic in proportion of 0.1% in lot L1(E) and in proportion of 0.25% in lot L2(E). In the experiment end, were effected control slaughtering of 5 chickens per each lot, to establish the meat quality by trenching and meat chemical composition. After YEA-SACC 1026 probiotic administration, as fodder supplement, the chicken meat quality was improved by increasing the weight of superior quality meat in carcass. The obtained results confirm the favourable effects of probiotics on chicken meat production and its quality

Due to the current global health problem of antibiotic resistant recently announced by the World Health Organization, there is an urgent necessity of looking for new alternative antibacterial materials able to treat and impede multidrug-resistant infections which are cost-effective and non-toxic for human beings. In this regard, carbon nanofibers (CNFs) possess currently much lower cost than other carbon nanomaterials, such as graphene oxide, and exhibit excellent chemical, mechanical and electric properties. Furthermore, here, the first report on the antibacterial activity of CNFs was demonstrated. Thus, these nanomaterials, in pure form or incorporated in a minuscule amount into calcium alginate composite films to reduce production costs as much as possible, showed to be new weapons against a globally spreading multidrug-resistant pathogen, the methicillin-resistant Staphylococcus epidermidis (MRSE). This Gram-positive bacterium is becoming one of the most dangerous pathogens, due to its abundance on skin. In this study, these hollow filamentous materials, in direct contact with cells and loaded in the low-cost calcium alginate composite films, showed no cytotoxicity for human keratinocyte HaCaT cells, which render them very promising for biomedical applications. The CNFs used in this work were characterized by Raman spectroscopy and observed by high-resolution transmission electron with energy-disperse X-ray spectroscopy.

Atmospheric Water

Worldwide, the shortage of fresh water has increased exponentially due to population growth and contamination of available water, especially in water tables that provide water for general consumption. One of the main pollutants of water is arsenic (As), present in the environment and in most mining/metallurgical processes, which is a major health risk, especially as a carcinogen. In the region of Matehuala, San Luis Potosi (SLP), Mexico, a highly productive mining area, arsenic concentrations of 138.1 mg/kg have been found in soils—6.2 times higher than what is allowed in domestic soils, while in water it is reported up to 158 mg/L, exceeding permissible limits for human consumption. In addition to As pollution, the region suffers from water shortage both in the city and in rural communities. Therefore, it is necessary to explore new technologies to provide the population with fresh water. This paper presents a feasibility study on the use of an atmospheric water generator (AWG) to capture fresh water in the region of Matehuala, SLP. The region was found to have the necessary environmental conditions to use AWGs, with an annual average relative humidity (RH) of approximately 60%. Using a mathematical model of a dehumidifier, water harvesting can be evaluated under the region’s prevailing climatic conditions. The month with lowest harvest was found to be January, with 0.89 to 3.6 L/day, while the month with largest harvest was August at 3.9 to 18 L/day and water production costs of 0.0093 and $ 0.038 USD/L, respectively. The study concludes that the use of AWGs would help alleviate water shortages, thus benefiting marginalized people or communities, preserving ecosystems and the environment.
