The feed restriction program is on of the main techniques in growth curve manipulation for increasing production efficiency in broiler chicken. Quantities and qualitative feed restriction are procedures that can be used to manipulate the feeding strategies of poultry in order to decrease growth and metabolic rate to some extent and so alleviate the incidence of some metabolic diseases such as a...

This study was conducted to compare growth performance, carcass characteristics and meat quality of 4 breeds of local chicken. A total of 480 1-d-old chicks were distributed to 16 pens, with 4 treatments of breed, 4 replicates and 30 chicks per pen. Three Korean local breeds of white-mini broiler, Hanhyup-3-ho, and Woorimatdag, and a breed of silky fowl were raised under identical rearing and f...

This research aimed to increase functional value of broiler-chicken meat containing high antioxidant and low cholesterol through substitution of soybean meal (SBM) with Indigofera zollingeriana top leaf meal (ILM). The experiment used 160 day old broiler chicken (Cobb strain). The experimental chicken were provided dietary treatments when they were 15-days old (initial body weight of 460.5±1.56...

This experiment was conducted to assess the effect of chicken genotype on the growth performance, feed intake and feed conversion efficiency of the progenies resulting from purebred (Giriraja (Gr) X Giriraja (Gr)), straight (Gr male X Alpha female), reciprocal (Alpha male X Gr female) and Alpha male X White Leghorn (WL) female crosses. Data obtained on body weight, body length, breast girth, ke...

The effect of Aspergillus niger hydrolysis on cassava peel meal based diet on the growth performance and nutrient retention of broiler chickens was studied. Delignified cassava peel was used as the carbon source in a composed medium under a pH of 5.0, concentration 3% and 35C to grow Aspergillus niger for five days. The culture filtrate obtained was then used to hydrolyze delignified cassava pe...

Little is known about broiler chicken ranging behaviour. Previous studies have monitored ranging behaviour at flock level but whether individual ranging behaviour varies within a flock is unknown. Using Radio Frequency Identification technology, we tracked 1200 individual ROSS 308 broiler chickens across four mixed sex flocks in two seasons on one commercial farm. Ranging behaviour was tracked ...

background: according to literature, there are differences among different species of animals in respect to absorption of d-xylose. objectives: in two experiments, the differences that might exist in absorptive capacity of small intestine for d-xylose, in different types of chicken were tested. methods: in experiment one, 2 groups of nine adult layer type males (48 weeks) and females (58 weeks)...

Global competition for high standard feed-food resources between man and livestock, such as industrial broilers, is a concerning problem. In addition, the low productivity of scavenger chickens in developing countries leaves much to be desired. Changing the ingredients, and therefore, the nutrient composition of feed intake by commercial fed as well as scavenger chickens seems like an obvious s...
