“…The same response could apply to development of visceral organ development. These results agreed with those of previous researchers ( Al-Masri, 2006 ; Xavier et al, 2012 ) who observed similar growth of digestive organs in broiler chicks on diets based on animal or VP ingredients. It is generally known that visceral organs associated with digestive function develop most rapidly in the first 7 to 10 days of life ( Nitsan et al, 1991 ; Iji et al, 2001a , b ).…”

This study consisted of two experiments, conducted to assess the impact of phase at which vegetable protein (VP) diets are introduced to broiler chicks, and preference of birds for diets based on soybean or canola meal (CM). Two hundred and ten day-old Cobb 500 chicks were randomly distributed into five dietary groups in the main experiment. One group was fed on animal protein (AP) diet all through to 21 days of age; two other groups were started on AP diet for 7 days and then switched to diets containing soybean meal (AP-SBM) or AP-CM, while two other diets (SBM-AP and CM-AP) were started on one of the VP diets for 7 days and then switched to AP diet. A sub-experiment on thirty birds raised on a commercial diet to 7 days was used in a feed selection test to quantify the preference of birds for the diets containing mainly CM or SBM. Chicks were reared under similar care and management conditions and the diets were iso-caloric and iso-nitrogenous. Results of the main experiment showed that chicks on CM-AP diet ate more (p<0.05) than those on the other diets up to day 7. Body weight gain was highest (p<0.001) on the AP-SBM diet while birds on the CM-AP diet weighed the least at 7 d. Feed intake, body weight gain, feed conversion ratio, mortality, bone growth, visceral organ development, and activities of digestive enzymes were similar between the groups from hatch to 21 days of age. Results of the second sub-experiment showed that chicks preferred the CM-based diets to the SBM-based diets at 8 to 14 d (p<0.001) and 15 to 21 d (p<0.01) when given a choice. Overall, the birds were not affected by the nature of the starter diet although they tended to prefer the canola to soybean diets.

“…Observou-se decréscimo do ganho em peso das codornas à medida que houve aumento de inclusão dos níveis de FP nas dietas, segundo a equação: GP= 105,723 -1,3147FP (R 2 = 0,75). O que possivelmente se justifica pelo fato de que a proteína da FP apresenta em sua conformação estrutura terciária muito complexa comparada à proteína vegetal, e essa estrutura contém grande quantidade de aminoácidos sulfurosos ligados a pontes dissulfeto, que, por sua vez, possui baixa solubilidade e alta resistência à ação das enzimas proteolíticas, necessitando de hidrólise para ser metabolizada pelo animal, conforme relatado por Xavier et al (2012). Além disso, aves jovens não sintetizam enzimas suficientes, o que justifica, em partes, a redução na retenção do nitrogênio e, consequentemente, menor ganho em peso pela dificuldade em digerir a proteína (Aletor et al, 2000;Sklan, 2001;Noy e Sklan, 2002).…”

Objetivou-se avaliar a inclusão de farinha de penas (FP) em dietas reduzidas em proteína bruta (PB) e aminoácidos (AA) para codornas de corte. Foram utilizadas 240 codornas de corte machos nas fases de 8 a 21 dias e 8 a 35 dias de idade, distribuídas em delineamento inteiramente casualizado, em esquema fatorial 2 x 3 (duas dietas: controle positivo (CP) e controle negativo (CN) reduzida em PB e AA em relação ao CP x três níveis de inclusão de FP: 0, 5 e 10%), totalizando 6 tratamentos, com 4 repetições de 10 codornas por parcela. Houve interação (P<0,05) entre a inclusão de FP e as dietas para o consumo de ração na fase de 8 a 21 dias, bem como efeito da inclusão de FP e das dietas para o ganho em peso e conversão alimentar. No período de 8 a 35 dias não houve efeito (P>0,05) da interação entre os fatores, mas efeito (P<0,05) da inclusão da FP para o consumo de ração, e para a inclusão da FP e as dietas para ganho em peso e conversão alimentar. A utilização de FP, em qualquer nível utilizado não afetou (P>0,05) as variáveis de carcaça, exceto para o rendimento de coxa + sobrecoxa (P<0,05) que foi melhor com o CN. A FP pode ser utilizada em até 5% sem ocasionar danos ao desempenho das codornas. A dieta CN, com redução de PB e AA não apresenta uma boa estratégia para melhorar o desempenho das codornas.

“…There are studies suggesting that pre-starter feeds with different raw materials affect the development of the intestinal system (Longo et al, 2007;Lamot, 2017;Sousa et al, 2021). However, there are also studies that different types of pre-starter feeds with different raw material compositions have no effect on internal organ development (Bellaver et al, 2005;Laboisssiere, 2008;Ullah et al, 2012;Xavier et al, 2012). Healthy live and productivity of animals are associated with microbial development of the intestines as much as it is associated with digestive system development.…”

The purpose of the study is to determine the effects of pre-starter feed prepared using different sugar sources on the performance, carcass parameters, internal organs and intestinal development, microbial load in broilers. In total, 360 newly hatched chicks divided into 4 treatment groups with 5 replicates. 18 chicks with similar live weights (9 male, 9 female) were used for each replicate. Control or pre-starter feeds (containing %14 saccharose, %14 dextrose, or %7 saccharose+ %7 dextrose) were used for the feeding of the groups. For the feeding of the control group, standard chick starter feed was used for the first 5 days; for the treatment groups, the pre-starter feeds prepared were used. For the rest of the trial period, all groups were subjected to standard feeding. A significant difference was observed among groups with regards to live weight gain and feed conversion rate during the first four weeks of the study; however, this effect disappeared over the last week. In addition, it was determined that any differences observed with regards to carcass parameters other than hot and cold carcass weights, internal organ development aside from proventriculus, intestinal development and microbial load were not significant. It was concluded that the pre-starter feed prepared with saccharose and/or dextrose did not show the expected effect
