“…These table values are global averages of published values for nutrient contents from local as well as world-wide sources. Number of such databases are available from different organizations and countries; examples include WPSA (1986) , NRC (1994) , INRA (2002) , CVB (2016) , Evonik (2016) , FEDNA (2017) , Feedipedia (2017) and Rostagno et al.

“…For anyone perusing and comparing these databases, the inconsistency that exists among them will soon become clear. For example, AME values of 9.92, 9.71, 9.04, 9.80, 9.55 and 9.71 MJ/kg have been reported for soybean meal in NRC (1994) , INRA (2002) , CVB (2016) , Evonik (2016) , Rostagno et al.

Accurate knowledge of the actual nutritional value of individual feed ingredients and complete diets is critical for efficient and sustainable animal production. For this reason, feed evaluation has always been in the forefront of nutritional research. Feed evaluation for poultry involves several approaches that include chemical analysis, table values, prediction equations, near-infrared reflectance spectroscopy, in vivo data and in vitro digestion techniques. Among these, the use of animals (in vivo) is the most valuable to gain information on nutrient utilization and is more predictive of bird performance. However, in vivo methods are expensive, laborious and time-consuming. It is therefore important to establish in vitro methods that are reliable, rapid and practical to assess the nutritional quality of feed ingredients or complete diets. Accuracy of the technique is crucial, as poor prediction will have a negative impact on bird performance and, increase feed cost and environmental issues. In this review, the relevance and importance of feed evaluation in poultry nutrition will be highlighted and the various approaches to evaluate the feed value of feed ingredients or complete diets will be discussed. Trends in and practical limitations encountered in feed evaluation science, with emphasis on in vitro digestion techniques, will be discussed.

“…Apesar do consumo de ração das aves não ter apresentado diferença significativa, notou-se, um consumo de ração numericamente menor das aves alimentadas com a dieta controle, onde este grupo apresentou valores de consumo próximos aos recomendados por Rostagno, et al, (2017), em que o consumo de ração para codornas japonesas na fase de postura com peso médio de 190g é de 25.85g/ave/dia. O que nos leva a acreditar que promova uma melhoria na digestibilidade dos nutrientes acelerando o processo de digestão, promovendo consequentemente aumento no consumo, mas melhoria na produção de ovos.…”

The use of betaine associated or not with choline chloride 70% in Japanese quail diets in the laying phase was evaluated. 504 Japanese quails (Coturnix cortunix Japonica) were used from 104 to 208 days old, in a 3x2 + 1 factorial design, completely randomized design, seven treatments, nine replications, eight birds per experimental unit. Betaine was supplemented in 20% of the digestible methionine level of the control diet, in diets with reformulated betaine the level of enrichment was in the nutritional matrix of the product (100%) and with an extra recovery of 5% (105%). Choline chloride was fixed at 0.07%. Productive performance, egg quality, histometry, and the number of goblet cells from the duodenum and hepatic glycogen were analyzed. The use of betaine promoted greater weight of the eggs to the control, regardless of the mode of use, the use of choline promoted a superior result in the weight of the eggs. In egg quality, only shell percentage was influenced. The use of the reformulated betaine 100% of the matrix promoted greater height of the villi, and a lower villus: crypt ratio to the treatment with the reformulation enriched by 105%. Hepatic glycogen was not influenced. In goblet cells, the reformulation in an extra 105% of the matrix was superior to the matrix in 100%. The hill reduced villus height, improved villus: crypt ratio, and number of goblet cells. In conclusion, the reformulated betaine enriched in an additional 5% of its nutritional matrix replaces the use of choline chloride in the laying of Japanese quail diets.

“…The gilts were fed ad libitum twice a day (at 07:00 am and 1:00 pm) during the grower phase (130 days). After this period, the feed intake was adjusted according to [18]. The diets were based on corn and soybean feedstuffs and did not contain any oil as an ingredient (Table 1).…”

The concern with human health has increased the interest in producing foods enriched with polyunsaturated fatty acids (PUFA), directly or naturally by inclusion in the animals' diet. The positive effects such as antithrombotic, anti-inflammatory, and hypolipidemic have been observed in pigs and rats, used as human models for study. The present study evaluated the effect of cow's milk with different lipid profiles on performance, serum fatty acid profile, biochemical analysis, and a complete blood count of gilts used as a human model. At 34 days, thirty gilts were equally distributed in three treatments. Experimental treatments were milk from cows without the oil supplementation (C), milk from cows fed an enriched diet with linseed oil (n-3), and milk from cows fed an enriched diet with soybean oil (n-6). Milk supplementation was performed until the age of 190 days, provided once in the morning. The n-3 and n-6 milk reduced the concentration of myristic acid in the blood and increased the leukocytes. Milk enriched with n-3 compared to n-6 reduced stearic acid. In conclusion, milk with a better PUFA profile can reduce saturated fatty acids in the blood and alter the concentration of cells in the defense system
