Vegetable waste (spinach, potato, and cauliflower) is a rich and natural source of nutrients, potentially good for supplying minerals, essential amino acids, and antioxidants to the birds. Relatively, its cost very low, easily to accessible, easily process & pose little risk of illness. The aim of present study was to evaluate the effect of vegetable waste (VW) as feed supplement on growth performance and hematology of broiler chicks. For this purpose, a total of 200 (4 days old) vaccinated chicks were acquired from a commercial hatchery Multan which was acclimated for three weeks (21 days) on basal starter feed after that 25-day-old chicks with uniform body weight were allocated according to a CRD (completely randomized design) into four dietary treatments with three replicates of each contained 15 chicks in 12 pens. In dietary treatments, chicks were feed with basal feed (BF) and supplemented feed with vegetable waste (VW) of spinach, potato, and cauliflower. For this purpose, the dietary treatments included control treatment ( T 1 ) (100% BF+0% VW) and other dietary treatments ( T 2 ) (75% BF+25% VW), ( T 3 ) (50% BF+50% VW), and ( T 4 ) (25% BF+75% VW). The body weight, feed intake, food conversion ratio (FCR), and mortality were checked on weekly and daily basis. For hematology analysis, after the 1st experimental week (25-day-old chicks) and the last 5th experimental week (56-day-old chicks), the samples of blood were gathered from the wing’s veins of two birds from each treatment in random way. At the end of five weeks (35 days), birds with uniform average body weight were selected per treatment with three replicates (2 bird/replicate) and then were manually slaughtered according to the Halal method to analyze the weight of internal body organs of broilers by physical and statistical analysis (ANOVA). There was no significant effect ( P > 0.05 ) on feed intake and FCR among all the dietary treatments. But in average, body weight and BWG were higher in treatment ( T 2 ) ( P < 0.01 ) than all other dietary treatments ( T 3 ) and ( T 4 ) and control treatment ( T 1 ). The blood constituents in this study showed that broilers in control treatment ( T 1 ) and other dietary treatments ( T 2 ), ( T 3 ), and ( T 4 ) fed on different doses were significantly ( P < 0.01 ) different from each other. The week 5 ( W 5 ) shows higher values of blood constituents ( P < 0.01 ) than week 1 ( W 1 ). The carcass yield of the chicks fed on different doses showed that they were significantly different ( P < 0.01 ) among the dietary treatments. The VW inclusion 0%, 25%, 50%, and 75% had positive effect on blood constituents and carcass yield of the broiler chicks; they were significantly ( P < 0.01 ) different among the treatments.

n experiment was carried out to determine the effects of adding potato chips by-product (PBP) to Golden Montazh chick's diets (starter and finisher) on productive performance, carcass characteristics, and economic evaluation. Five levels of PBP representing 0.0 (control), 2.5, 5.0, 7.5 and 10.0% were used during starter (0-6 weeks) and finisher (7-10 weeks) in five dietary treatments (T1-5). 225 one day old unsexed of Golden Montazh chicks were divided equally into 5 dietary treatments in 3 replicates of 15 chicks each. All birds are kept under the same condition. Feed and water were supplemented ad-libitum. Three birds from each treatment were randomly chosen at the conclusion of the experiment, slaughtered, and their carcasses were measured, and their meat samples were taken. Results revealed no significant differences between treatments in live body weight, body weight gain, feed consumption, or feed conversion ratio.The percentages of carcass and total edible parts (TEP) were increase significantly when chicks fed diets containing 7.5% PBP compare with control (T1); however, the percentages of liver, gizzard, heart, or total giblets hadn't affected by different treatments. Chemical composition of meat (protein, ether extract, and ash) as percentages on dry matter basic showed that ash% hadn't affected by different treatments, on the other hand, ether extract % increase significantly in all treated groups compare with control and the opposite was recorded in crude protein%. The results of economical evaluation showed that potato chips by-product could be included at 2.5 and 5% in chicks' diets to support and enhance economic efficiency.Conclusion: From the present results it could be stated that adding potato chips by-product at inclusion rate of 5% to Golden Montazh diets as a replacement of yellow corn, would have a positive effect on economic efficiency without any adverse effect on productive performance or carcass traits.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
