in this study, growth and survival of the caspian whitefish, rutilus frisii kutum, (mean weight 0.59±0.06g) have been estimated at different rearing salinities (0, 5 and 10‰) and temperatures (24 and 28˚c). maximum fish weight gain (493.65±14.07%) and specific growth rate (sgr) (2.74±0.15%), and minimum feed conversion ratio (fcr) (1.66±0.06) were obtained at salinity of 5‰ and temperature of 2...

This experiment was carried out to evaluate different levels of peppermint (Mentha piperita) plant powder usage on feed conversion ratio (FCR), body weight (BW), feed intake (FI), body temperature, carcass parts (breast and thigh) and internal organs (liver, heart, gizzard) weights in broiler chicken. A total of 192 broiler chicken were randomly divided into 4 experimental treatments with 4 rep...

The objective of this study was to assess the importance of strain and sex and their interaction effect on broiler chickens’ performance and susceptibility to ascites. Chicks from three strains (Ross 308, Cobb 500 and Arian, labeled as A, B and C respectively) were obtained from the same age breeder and sexed when one-day-old. Each crosses’ sex was assigned to four pens of 60 broilers each. Bod...

This study aims to determine the effects of local duck mating patterns (Tegal and Magelang) on production performance based feed consumption, conversion (FCR), egg (DDP). The research used 80 Magelang Tegal ducks. is an experimental with a completely randomized design (CRD). 4 treatments 5 replications. number ducks in each cross consisted (five) males 15 (fifteen) females. P1 crossed (MM), P2 ...

The objective of this paper was to derive economic weights for performance and survival traits of growing pigs including feed conversion ratio (FCR), daily feed intake (DFI), ADG, postweaning survival of the growing pig (SG), and carcass fat depth at the P2 site (CFD). An independent model was developed for each trait to derive economic values directly based on a typical Australian production s...

The effect of commercial selection on the growth, efficiency, and yield of broilers was studied using 2 University of Alberta Meat Control strains unselected since 1957 and 1978, and a commercial Ross 308 strain (2005). Mixed-sex chicks (n = 180 per strain) were placed into 4 replicate pens per strain, and grown on a current nutritional program to 56 d of age. Weekly front and side profile phot...

AIM The objective of this study was to investigate the dietary advantages of inclusion of unconventional nutrient source, i.e., Azolla in the basal diet of White Pekin broilers. MATERIALS AND METHODS All ducklings were randomly distributed into three treatment groups with three replicates each and each replicate having 12 ducklings and were reared in deep litter system. Groups were subjected ...

An experiment was conducted to evaluate the effects of hydroponics maize fodder on growth and nutrient digestibility weaned piglets from July 1st, 2017 August 11th, 2017, for six weeks. The consisted 75 days old, 15 crossbreed (Duroc x Nagpuri & Duroc) in a Completely Randomized Design with three treatments five replications. Treatment 1 (T1) contained 100% concentrate feed, 2 (T2) 90% feed...

the aim of this study was to evaluate the effects of three lighting programs on immune system and performance of broiler chickens. a total of 288 seven day-old male broiler chicks (ross-308) were randomly distributed between three treatments. each group was housed in the separated room with eight pen and 12-birds per pen. the management conditions were similar for all treatments throughout the ...
