Desempenho e rendimento de carcaça de frangos de corte alimentados com mistura de aditivos fitogênicos na dieta

O objetivo deste trabalho foi avaliar o efeito de misturas de aditivos fitogênicos na dieta de frangos de corte, sobre seu desempenho zootécnico e rendimento de carcaça. Foram avaliados 660 pintos de sexo misto, entre 1 e 42 dias de idade, em delineamento inteiramente casualizado, com cinco tratamentos e seis repetições de 22 aves (11 machos e 11 fêmeas). Além do controle, foram avaliados tratamentos com antibiótico (10 ppm de virginiamicina) ou com misturas de aditivos fitogênicos: mistura A, 150 ppm de óleos essenciais de alecrim, cravo, gengibre e orégano; mistura B, 150 ppm de óleos essenciais de canela, sálvia, tomilho branco e óleo-resina de copaíba; e mistura A+B, 50% da mistura A e 50% da B. A mistura B proporcionou maior ganho de peso e melhor conversão alimentar das aves, no período de 36 a 42 dias de idade. No período total do experimento, o antibiótico e a mistura B proporcionaram maior ganho de peso das aves. O consumo de ração foi maior com o antibiótico do que com o controle. A mistura A+B e o tratamento controle proporcionaram maior rendimento de coxa+sobrecoxa e maior peso relativo do baço. As mistura B e A+B apresentam potencial como melhoradores de desempenho para frangos de corte

Use of Sunflower Meal with Enzyme Mixture Substituted for Soybean Meal in Broiler Diets [Etlik Piliç Karma Yemlerinde Soya Küspesi Yerine Bir Enzim Karişimi Ilave Ederek Ayçiçegi Küspesi Kullanimi]

The study was carried out to investigate the effects of sunflower meal with an enzyme mixture containing ?-amylase, ß-glucanase, cellulase, lipase and protease substituted for soybean meal in broiler diets on performance, intestinal weight, viscosity and pH, as well as the frequency of sticky droppings and abdominal fat. In the trial, a total of 960 one-day-old Avian broiler chicks were used. The trial lasted 6 weeks. A total of 12 experimental diets were supplied ad libitum. Dietary treatments consisted of 15%, 25%, 35% soybean meal, or sunflower meal or sunflower meal with the enzyme mixture (0.05% and 0.10%). Enzyme supplementation to diets improved live weight gain. Enzyme supplementation to diets decreased intestinal weight, the viscosity of the intestinal digesta and the frequency of sticky droppings, although enzyme supplementation to diets increased intestinal pH. Enzyme supplementation did not affect abdominal fat except for 25% AK + 0.10% enzyme

Influence of Various Dietary-Protein Levels on Carcass Composition In the Male Japanese-Quail (Coturnix-Coturnix-Japonica)

WOS: A1995RU01500009PubMed ID: 85900931. The present study was conducted to determine the effect of various dietary protein concentrations on the carcase composition of male Japanese quail. 2. Six diets varying in protein from 160 to 300 g/kg and containing approximately 11.72 MJ/kg ME were fed for 5 weeks and analysed for dry matter, protein, fat and ash. 3. Treatments affected carcase weight, dry matter, protein, ether extract and ash (P < 0.01). 4. The water content of the carcases decreased with increasing dietary protein concentrations, while the carcase protein content increased with higher dietary protein. The carcases with the highest fat content were obtained from quail receiving the low protein diet

Use of sunflower meal with enzyme mixture substituted for soybean meal in broiler diets

WOS: 000172885000014The study was carried out to investigate the effects of sunflower meal with an enzyme mixture containing alpha -amylase, beta -glucanase, cellulase, lipase and protease substituted for soybean meal in broiler diets on performance, intestinal weight, viscosity and pH, as well as the frequency of sticky droppings and abdominal fat. In the trial, a total of 960 one-day-old Avian broiler chicks were used. The trial lasted 6 weeks. A total of 12 experimental diets were supplied ad libitum. Dietary treatments consisted of 15%, 25%, 35% soybean meal, or sunflower meal or sunflower meal with the enzyme mixture (0.05% and 0.10%). Enzyme supplementation to diets improved live weight gain. Enzyme supplementation to diets decreased intestinal weight, the viscosity of the intestinal digesta and the frequency of sticky droppings, although enzyme supplementation to diets increased intestinal pH.

Effect of antibiotic, prebiotic and enzyme mixture supplementation on performance and nutrient utilization of broilers

WOS: 000220808900004To study the effect of supplementation of antibiotic, prebiotic and an enzyme mixture on growth and nutrient utilization, 48 day-old chicks were divided into 4 groups (6 males, 6 females) and fed on, a standard ration with either no supplementation (C) or supplementation with antibiotic (CA), prebiotic (CP) or enzyme mixture (CE). Nutrient utilization was not affected by supplementation but excreta, viscosity decreased on prebiotic and enzyme mixture supplementation. Compared to C and CA feed, efficiency improved in CP and CE
