Phytate-phosphorus and phytase contents on the relative weight of organs, intestinal morphometry and performance of broilers.

ABSTRACT: In order to evaluate the efficiency of phytase in diets with low and high phytate phosphorus (PP) content, as a consequence of wheat bran inclusion, on the relative weight of organs, intestinal morphometry and performance, three hundred and eighty-four male Cobb500 broilers were housed in metabolic cages. Animals were assigned into four treatments in a 2x2 factorial scheme in a randomized block design with eight replicates of 12 birds each. From 11 days of age birds received experimental diets, which consisted of: Diet low in PP; Diet low in PP with phytase (500FTU kg-1); Diet with a high PP and Diet with a high PP with phytase (500FTU kg-1). At 22 and 32 days of age two birds were slaughtered in order to collect gizzard, heart, liver, cecum, cloacal bursa, and at 32 days, a portion of the duodenum, jejunum and ileum was collected for morphometric evaluation. From 22 to 32 days of age average feed intake, average weight gain, average body weight and feed conversion ratio were also evaluated. Data were subjected to analysis of variance, fixed effects of diet and phytase and interaction between factors as well as the random block effects were tested. There was no significant interaction for the variables studied, concluding that phytase in diets with low or high phytate phosphorus content did not change the relative weight of organs, intestinal morphometrics and performance; only isolated effects were observed. RESUMO: Para avaliar a eficiência da fitase em dietas com baixo e alto teor de fósforo fítico (PP), em função da inclusão ou não do farelo de trigo, sobre o peso relativo de órgãos, morfometria intestinal e desempenho, foram alojados 384 frangos de corte, machos da linhagem Cobb500, em gaiolas metabólicas. Os animais foram distribuídos em quatro tratamentos em um arranjo fatorial 2x2 em delineamento de blocos casualizados com oito repetições e 12 aves por unidade experimental (UE). A partir de 11 dias de idade as aves receberam as dietas experimentais, que consistiram em: Dieta com baixo teor de PP; Dieta com baixo teor de PP com fitase (500FTU kg-1); Dieta com alto teor de PP e Dieta com alto teor de PP com fitase (500FTU kg-1). Aos 22 e 32 dias de idade foram abatidas duas aves por UE para coletar a moela, coração, fígado, ceco, bolsa cloacal, e aos 32 dias foi coletada uma porção do duodeno, jejuno e íleo para avaliação da morfometria. No período de 22 a 32 dias de idade foram avaliados o consumo médio de ração, ganho de peso médio, peso médio corporal e a conversão alimentar. Os dados foram submetidos à análise de variância, onde foram testados os efeitos fixos de dieta e fitase e a interação entre os fatores, bem como o efeito aleatório de bloco. Não foi observada interação significativa para nenhuma das variáveis estudadas, concluindo-se que a fitase em dietas com baixo ou alto de PP não altera o peso relativo dos órgãos, a morfometria intestinal e o desempenho, apenas efeitos isolados foram observados.

Influence of Non-fibrous Carbohydrate and Degradable Intake protein and Ruminal Fermentation ,Nutrien Digestion and performance of Local Sheep

The objective of current study was to evaluate the impact dietary non-fibrous carbohydrate ( NFC) and ruminally degradable intake protein (DIP) concentration have on ruminal fermentation , nutrient digestion and performance of local sheep. The animal had a mean of  liveweight 19.80 ±1.55 kg. four diets ,arranged in a 2x2 factorial ,were formulated to contain either 40 or 50 % NFC and 50 or 60 % of dietary crude protein as DIP .dietary DM contained 25 % Indonesian field grass and 75 % concentrate. Solvent –extracted or formaldehyd  2 % -treated soybean meal were used to alter DIP and corn or soybean hulls to alter NFC level. Percentage of  energy and NDF digestion was similar ( p<0,01) as DIP level decreased in the diets. The soybean hulls was fermentable and total VFA concentration in the rumen increased ( p<0.01), but N-NH3 concentration was decreased ( p<0.01) as DIP level decreased in the diets. Daily live weight gain ( 146.29±25.84 g) and body composition ( fat, water , protein and mineral) was similar ( p<0.05) among diets. The preponderance ruminal fermentation ,nutrient digestion and performance of local sheeps did not be improved by sincronization of energy and nitrogen release but may more likely be limited by either energy or nitrogen alone.

As the base design was Randomized Completely Design with factorial design (2x3x3) that consisted of the first factor was sex (S) comprised : s1=male and s2=female. The second factor was feed from (P) comprised: p1=mush, p2=crumble and p3=Paste, whereas the third factor was slaughtering age (U) that comprised u1=six weeks and u2=eight weeks and u3=ten weeks. The investigated parameters were carcass weight, percentage of meat weight, meat weight of carcass. Result of the research obtained the lowest average of carcass weight for male entik aged 6.8 and 10 weeks respectively was 750.26 g, 1142.69 g, and the highest was 1024.93 g, 1336.08 g, and 760.40 g, 1098 g, 1180.26 g and the highest was 985.28 g, 1378.96 g and 1390.20 g. The lowest average parentage carcass for male entik respectively was 59.63%, 60.14%  and 61.76%; the highest was 57.17%, 61.02% and 67.86%. Whereas for the female  the lowest was 57.17%, 62.30%, and  61.02% and the highest was 68.99% ,67.59%, and 67.45 %. The average of meat carcass weight for the whole treatment was 733.99±158.23 g with range around 466.15 up to 956.42 g, and the highest average was reached by female entik aged eight weeks who was feeding by mash that was 916.95±39.36 g. The average of meat carcass weight was 64.57±1.35% with the range around 56.66 up to 73.60%. Result of  the analysis of variances showed that the interaction  factor between the sex, feed form ands slaughtering age affected no significantly (P>0.05) on the carcass weight, percentage of carcass weight, meat carcass weight and the percentage of carcass weight, meat carcass weight and the percentage of meat carcass weight and the percentage of meat carcass weight. Review for each treatment concludes that the sex factor highest effect just only for percentage of meat carcass weight (P<0.01), feed form factor had a high significant effect (P<0.01) on the carcass weight and the meat carcass weight, whereas the slaughtering age factor has a high significant effect linearly (P<0.05) on  the  percentage of carcass weight. This may concluded that the female entik  give the percentage of meat carcass weight more high then the male, feeding by mash form for entik which slaughtering eight weeks old increase the percentage of carcass weight and meat carcass weight.
