“…In relation to the feed intake variable (p> 0.05), the animals that received a micropelleted diet eventually consumed a smaller amount of the food, over the evaluation time. However, this result contradicts findings by Oliveira et al (2011), who concluded the opposite, with chickens fed with micropelleted feed had a higher food consumption, also in comparison with the meal.…”

The objective of this work was to evaluate the effects of two types of incubation and two types of feeding on the performance of chickens and intestinal development of chicks during the pre-starter phase (1 to 7 days of age). One-year-old male Ross® chicks were used. The experimental design was a randomized complete block design, in a 2x2 factorial design, with two types of feed processing (bran and micropelleted) and two types of incubation machines (single and multiple stage), totaling four treatments, with four treatment repetitions each. Twelve birds per experimental unit were used, totaling 192 animals. Performance evaluations were conducted, such as mean weight, weight gain, feed intake, feed conversion, bowel weight and size, and percentage of intestine in relation to live weight. Histomorphometric tests on the height of the villi and depth of the duodenal crypts were also performed. The two incubation machines did not influence any of the analyzed variables. Even though both had the same composition, the micropelleted feed resulted in positive gains for the performance variables: average weight, weight gain, feed intake, and feed conversion when compared to the meal, but was unable to significantly influence the morphometric measurements of the duodenum of chicks in the pre-starter phase.

“…The use of the same ingredient base (corn and soybean) for the formulation of the diet as well as the same line of the birds likely contributed to this result. Differences in yields of carcass and cuts are more common when different raw materials (Geron et al, 2015;Frank et al, 2016), lines (Api et al, 2017;Silva et al, 2017) and diet physical forms (Oliveira et al, 2011) are used.…”

This experiment was undertaken to compare the effects of using the Enzymmix F product with a Brazilian enzyme blend in diets with different nutritional levels. A total of 1,080 male broiler chicks were distributed into a randomized-block design with a 3 × 2 factorial arrangement consisting of three enzyme complexes (Enzyme Blend, Enzymmix F, and the combination of both) and two nutritional levels (regular and reduced). We evaluated the birds' performance in the periods of 1 to 21 and 1 to 42 days of age. The yields of carcass and cuts and intestinal integrity were evaluated at 45 days of age. During the analyzed periods, no significant difference was observed for the performance parameters considering the "enzyme" factor. However, the reduction in the nutritional level of the diet resulted in inferior performance in both periods. There was no statistical difference for the yields (%) of carcass and cuts. Enzymmix F provided the greatest villus height in the jejunum segment. The use of the Enzyme Blend in the nutritionally reduced diet led to a lower crypt depth. In conclusion, Enzymmix F increased the weight of wings (g) and the villus height in the jejunum.

“…O maior PC das aves que receberam dietas na forma expandida peletizada, está ligado às transformações químicas que o processo realiza no alimento, como o aumento na gelatinização do amido, proporcionando melhor aproveitamento dos nutrientes pelo animal. Resultado semelhante foi encontrado por Oliveira et al (2011) que constataram que frangos de corte alimentados com dietas expandidas peletizadas apresentam maior GP no período de 1 a 21 dias do que as aves alimentadas com dietas fareladas. O CO das aves alimentadas com 20% de FAP foi inferior ao das aves que receberam dieta convencional.…”

“…Aves alimentadas com dietas peletizadas apresentaram CO superior àquelas que foram alimentadas com dietas fareladas ou expandidas peletizadas. Esse resultado não corrobora com estudos realizados por Oliveira et al (2011), que avaliaram diferentes processamentos em dietas para frangos de corte, mostraram que as aves alimentadas com dietas expandidas peletizadas apresentaram maior consumo de ração no período inicial em comparação a aves alimentadas com dietas peletizadas. O fator processamento apresentou diferenças significativas na CA dos pintos no período avaliado (P<0,0001), onde as aves que consumiram dieta na forma expandida apresentaram melhor CA que as aves que receberam dietas na forma farelada ou peletizada.…”

RESUMO O objetivo neste estudo foi avaliar o desempenho zootécnico de frangos de corte de 1 a 7 dias de idade alimentados com a inclusão de 20% farelo de arroz parboilizado (FAP) na dieta com diferentes processamentos. O delineamento utilizado foi em esquema fatorial 2x3, dois tipos de dietas (uma a base de milho e a outra com a inclusão de 20% FAP) e três tipos de processamento: dietas farelada, peletizada e expandida peletizadas todas isonutritivas. As rações foram peletizadas a uma temperatura de 85°C e expandidas em uma faixa de temperatura de 110°C a 115°C. O estudo foi realizado em aviário experimental composto por 60 boxes experimentais. Cada unidade experimental foi composta por 58 pintos de corte machos da linhagem Cobb 500® de um dia de idade. Foram utilizados seis tratamentos com 10 repetições por tratamentos. Foram avaliadas as variáveis de desempenho aos 7 dias de idade. As médias quando apresentaram diferenças a nível de 5%, foram comparadas pelo teste de Tukey. As variáveis analisadas não apresentaram interação significativa (P<0,05) no período avaliado. Pintos de corte alimentados com a inclusão de 20% FAP na dieta apresentaram menor peso corporal, ganho de peso e consumo de dieta aos 7 dias de idade. O processo de expansão + peletização promove melhora no peso aos 7 dias de idade e no ganho de peso dos pintos até os 7 dias de idade.
