Abstract:

Global meat consumption per capita is expected to increase ~40% from 2019 to 2050. Over 30% of the total cropland worldwide is currently being used to produce either livestock and poultry feed or silage to meet the demand. One solution to reduce cropland use for animal feed is to increase the production of alternative protein sources. The primary protein sources for animal nutrition, including soybeans, peas and fish meal, are of increasing demand and are subsequently becoming more expensive, making their long-term use unsustainable.

Abstract Current nutritional strategies of livestock industry are focused on evaluating the effects of terrestrial sources rich in natural bioactive compounds that can be used in farm animal feed and the subsequent implications on the quality of resulting animal products. In this context, the present study aimed to characterize from a nutritional point of view some natural plants used as phyto-additives in poultry nutrition: oregano, mint, basil, sage, fenugreek, thyme, turmeric, cumin and rosemary. The results of this study on plants nutritional evaluation showed a varied proximate analysis.

Abstract The consumption of poultry meat and eggs is expected to increase considerably in the nearest future, which creates the demand for new poultry feed ingredients in order to support sustainable intensive production. Moreover, the constant improvement of the genetic potential of poultry has resulted in an increased nutrient density in poultry feeds, which limits the possibility to include low quality feed ingredients. Therefore, the feed industry needs new sources of highly digestible protein with a desirable amino acid composition to substitute other valuable but limited protein sources

Abstract:

AbstractThe excretion of large amounts of P in effluent from intensive pig and poultry units is indicative of the poor availability of phytate-bound P in plant-derived feed ingredients. This environmental problem prompted the development and acceptance of microbial phytase feed enzymes for single-stomached animals. Their introduction led to an increasing recognition that phytate may have adverse effects on protein utilisation in addition to P. Consequently, the nutritional relevance of protein–phytate interactions for pigs and poultry is considered in the present review. Since the current unde

Abstract:

A study was conducted to investigate the variability in chemical and nutritive composition of wheat screenings, bakery by-products and wheat mill run used by the feed industry in Canada. On average, and in comparison to wheat (as-fed basis), the wheat screenings (16 samples) contained less starch (457 vs. 560 g kg-1; P < 0.0001), less available energy (TMEn) (13.19 vs. 13.76 MJ kg-1; P < 0.05), similar amounts of sugars (19 vs. 12 g kg-1; P > 0.05), phytate phosphorus (2.4 vs. 3.0 g kg-1; P > 0.05), and higher levels of protein (151 vs. 126 g kg-1; P < 0.0001), fat (66 vs. 12 g

Abstract:

Broiler chickens grow rapidly, and their nutrient requirements change daily. However, broilers are fed three to five diet phases, meaning nutrients are under or oversupplied throughout production. Increasing diet phases improves production efficiency as there is less time in the production cycle that nutrients are in under or over-supply. Nevertheless, the process of administering four or more diets is costly and often impractical. New technologies are now available to blend feed to match the daily nutrient requirements of broilers. Thus, the aim of this review is to evaluate previous studies

Abstract:

The increase of animal and poultry production can be achieved by the effective use of fodder, including vegetable feed. However, it is known that the vegetable feed can contain anti-nutrients (phytic acid or its salts). They reduce the nutrient availability in the diet. That is why, the research aim is the description of the phytate influence on the body and the definition of the right feed phytases for fodder production. Phosphorus is responsible for the energy supply to the body for metabolic processes. It plays a significant role in the metabolism of proteins, fats and carbohydrates. It tak

The consumption of traditional foods such as fish and dates have declined, while that of processed foods, fat, eggs, meat, poultry and milk products have risen. The daily per capita intake of animal protein and fat have increased at the expense of carbohydrates. Some factors responsible for this change are increasing income and literacy, food price fluctuations, food subsidy policy, the influence of immigrant food habits, influence of mass media and the changing stru

The provision of dietary energy will influence the intake of all other nutrients. Broilers exhibit an outstanding ability to control their energy intake by adjusting their feed intake as diet energy concentration changes. There is still considerable debate on the accuracy, precision and usefulness of different procedures used for determining ME values of diets and ingredients.

In vitro analyses may be applied to dry- (DMD) and organic-matter (OMD) digestibility and crude protein (CP) degradability (DG) and may involve ‘live’ cultures such as rumen fluid or gastric juices or ‘dead’ extracts containing enzymes.
