Providing bees with benign and sufficient protein feeds is the key to successful beekeeping. Protein feed significantly affects on certain functions of individuals and the vital activity and productivity of the bee colonies. So, as a result of increased consumption of protein feed during the first days of life the supply of proteins in the body significantly increases in young bees, hypopharyngeal glands and other organs become developed, which provides the ability to perform various tasks depending on age and living conditions. Older bees consume protein for tissue renewal with new cells and

In the presented work, the issue of the use of protein feeds with biologically active additives to increase the nutritional value of artificial feeds is considered. This approach makes it possible to introduce various sources of protein, amino acids, vitamins into the bee feed, as well as enzymes to relieve the load on the bee's body for digesting substances, growth-stimulating drugs based on organic acids, etc. Experiments conducted in 2018 on feeding candi bees to the composition, which included isolated soy protein, apple cider vinegar, showed the following results.

Нoney bees (Apis mellifera L., 1758) perform a global plant pollination function. For normal development, bee colonies need to meet their nutritional needs. The study aims to determine the effectiveness of artificial bee feeding to increase their flight activity on pollinating fruit crops. To achieve this goal, a scheme for the use of artificial feeding was developed and the optimal set of feeds was selected as well as the influence of artificial feeding on an increase of colony strength and the flight activity of bees was investigated.

Intensively finished beef cattle have traditionally been fed rations based on rolled mineralised barley with a protein supplement such as soya bean or rapeseed meal. Since feed accounts for 75-85% of the variable costs of intensive beef production systems (MLC 1999) the use of alternative feeds that have a lower cost per unit of energy are worthy of investigation. The objective of this trial was to evaluate feeding pressed sugar beet pulp ensiled with dried maize distillers grains (Praize, Trident Feeds) on the performance of fast finishing continental cross weaned suckled bulls.

Feeding cost of animals is a major determinant of profitability in livestock production enterprises. Genetic selection to improve feed efficiency aims to reduce the cost of feeding in beef cattle production and thereby improve profitability.

Sugar intake is linked to developmental programming of obesity and diabetes. We hypothesized that supplementing ground beef in place of sugar during pregnancy would reduce fetal and offspring developmental programming. Gestating sows were fed 1 of 4 isocaloric supplements: control, ground beef, granulated sugar, or beef plus sugar. In the fetal study supplements were fed from d 40 to 110 of gestation and in the offspring study from d 40 until weaning. Gene expression differences in fetal liver and muscle were observed for IGF2 (P = 0.04), FBPase (P = 0.03), and IGF2R (P = 0.02). Differences we

The possibility of using the studied biopreparation in the feeding ration of trout as an active additive with an immunocorrecting effect has been proven. The use of a Chlorella suspension at a concentration of 10 ml / kg increases the survival and resistance of trout jewels, as well as the general strengthening of the immune background of the fish organism.

The fate of transgenic DNA (tDNA) and protein from feed derived from Genetically Modified organisms (GMOs) in animals has been a major issue since their commercialization in 1996. Several studies have investigated the risks of horizontal gene transfer (HGT) of tDNA and protein to bacteria or animal cells/tissues, but some of the reported data are controversial. Previous reports showed that tDNA fragments or proteins derived from GM plants could not be detected in tissues, fluids, or edible products from livestock. Other researchers have shown that there is a possibility of small fragments ente

Spinning process for the medium- and small-lot production of axisymmetric components has many advantages, such as smaller deformation force, simpler tool-and-die design, and lower investment in equipment, over conventional forming processes. It has been widely used in aerospace, energy and defense industry. This paper presents a 3-D elastoplastic finite element (FE) model for the simulation of the shear spinning process, in order to study deformation behaviour and design proper process parameters for the spinning process. The proposed model has the following characteristics: i) a shell element

Pastures are a major low cost source of feed in beef cattle. Their sustainable use and management affect to the economic performance of farms and to their conservation as a natural resource. Pastures are the subject of agronomic, zoos engineering and economic research, which report negative trends in their territorial scope, composition and productivity as a whole. In beef cattle breeding, the long-term goal is to use high-productivity pastures, which will increase the yield of meat from them, because poor pastures require feeding the cattle with other feed, which reduces profitability.

One of the major issues for the development of the livestock sector in Sri Lanka is the unavailability of quality animal feeds. Thus, this study was carried out to prepare value-added silages using fruit peels for feeding livestock. Silage has been prepared using pineapple (Ananas comosus) and papaya (Carica papaya) fruit peels obtained from a fruit processing factory in Sri Lanka. Ensiling was done either in fruit peels only or in different combinations of fruit peels and chopped Hybrid Napier (CO-3 Pennisetum perpureum × Pennisetum americarnum) grass.

The FAO has projected a doubling in world demand for seafood during the 21 ed from aquaculture of marine fish and shrimps fed primarily on fishmeal-based aquafeeds. However, current practices of high intensity monoculture of shrimp in coastal ponds and fish in offshore pens have been strongly criticized as being ecologically and socially unsustainable. This view derives from un- checked eutrophication of coastal marine ecosystems from fish farm effluents, and the destruction of coastal estuarine ecosystems by shrimp farm constructions, plus aquaculture’s reliance on wild-caught small fish - wh

Feed inputs represent the largest variable cost of producing meat and milk from ruminant animals. Thus, strategies that improve the efficiency of feed utilization are needed to improve the global competitiveness of Israeli and U.S. cattle industries, and mitigate their environmental impact through reductions in nutrient excretions and greenhouse gas emissions. Implementation of innovative technologies that will enhance genetic merit for feed efficiency is arguably one of the most cost-effective strategies to meet future demands for animal-protein foods in an environmentally sustainable manner.

The hypothalamic melanocortin system plays a central role in the regulation of food consumption and energy homeostasis in mammals. Accordingly, our working hypothesis in this project was that genetic editing of the mc4r gene, encoding Melanocortin Receptor 4 (MC4R), will enhance food consumption, feed efficiency and growth in fish. To test this hypothesis and to assess the utility of mc4r editing for the enhancement of feed efficiency and growth in fish, the following objectives were set: Test the effect of the mc4r-null allele on feeding behavior, growth, metabolism and survival in zebrafish.

Honey bee (Apis mellifera) colony losses pose a severe risk to the food chain. The IAPV (Israeli acute paralysis virus) was correlated with CCD, a particular case of colony collapse. Honey bees severely infected with IAPV show shivering wings that progress to paralysis and subsequent death. Bee viruses, including IAPV, are widely present in honey bee colonies but often there are no pathological symptoms. Infestation of the beehive with Varroa mites or exposure to stress factors leads to significant increase in viral titers and fatal infections. We hypothesized that the honey bee is regulating/

Many organizations and programs have begun to provide services and support to AIDS-orphaned children in East and southern Africa. Typical program components include the provision of school fees and supplies, supplementary feeding, home-visiting programs in which community members visit and assist affected children, and vocational training. However, few of these programs have been formally evaluated for impact. This paper reports on baseline findings from a study of two programs for AIDS-affected children and their families implemented by PLAN International in the Luwero and Tororo districts of
