| contents | Early feeding to modify digestive enzyme activity in broiler chickens Milagro León T Gerardo Garrido G María Castañeda D Emma Rueda de A Veterinaria diet Feeding enzymes broiler chickens ( Source: Agrovoc ) Objective. To evaluate the effect on digestive enzyme activity in broiler chickens by providing food in the first 48 hrs. after birth. Materials and methods . After incubating 300 fertile eggs from Hubbard breeding and immediately after hatching, the chicks were randomly assigned to treatments: fasting (from hatching to 48 hrs.); Hydrated Balanced Food (HBF) from birth to 48 hrs.; commercial hydrating supplement (CHS) from birth to 48 hrs. The diets were provided ad libitum . After 48 hrs. a commercial diet was fed. At birth and at 48 and 72 hrs. of age 30 chicks/treatment were sacrificed to determine the enzyme activity of maltase, sucrase, alkaline phosphatase, phytase, a -amylase, trypsin and lipase in samples of duodenal or pancreatic homogenate. Results . The supply of HBF or CHS during the first 48 hrs. of life increased the activity of maltase, sucrase and phytase in the first 3 days of life, with values between 1.2 and up to 4-fold compared to the control (p<0.05). Chickens that fasted for the first 48 hrs. had higher activity of the pancreatic enzymes a -amylase, trypsin, and lipase at 72 hrs. of life (p<0.05). Conclusions. The food supply in the first 48 hrs. after hatching increases the duodenal enzyme activity in the intestinal brush border during the first 3 days of age in broiler chickens. 2014 artículo científico 0122-0268 https://www.redalyc.org/articulo.oa?id=69332509012 en http://www.redalyc.org/revista.oa?id=693 Revista MVZ Córdoba application/pdf Universidad de Córdoba Revista MVZ Córdoba (Colombia) Num.3 Vol.19 |
