“…This study agreed with the results of Tamir and Tsega [ 29 ] who used the dried level of SPLM (sweet potato meal) at 0, 50, 100, 150, and 200 g/kg level which showed that drumstick, breast meat, and thighs are not affected with the dietary supplements because that material did not contain any dangerous effect on the health status and performance of the broiler chickens. The giblets' weight and the slaughter weight of broilers decrease with the increase of the supplemented feed as 100 g/kg dried sweet potato meal had gave higher giblets weight than 150 g/kg and 200 g/kg dried sweet potato meal.…”

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.

“…Statistically similar results in the growth performance indices indicated that the utilization of unpeeled sweet potato meal as partial replacement for maize in broiler finisher diets up to 15% did not negatively affect the growth rates, as it stimulated similar growth responses in the finisher broiler chickens. This result was similar to the reports of Ayuk and Essien (2009) and Tamir and Tsega (2009) who observed no significant differences in the daily feed intake, weight gain, feed conversion ratio, and mortality rates of broiler chickens fed diets containing sweet potato as replacement for maize. Haemaological parameters are used to evaluate health status of animals and to assess the degree of environmental, nutritional and pathological stress (Afolabi et al, 2010).…”

This study evaluated effects of unpeeled sweet potato meal (USPM) on performance of finisher broiler chickens. A total of 180 one day-old broiler chicks were used for the experiment. Brooding operation was carried out for 2 weeks. Thereafter, the broiler chickens were managed for additional 2 weeks with provision of starter diet and water ad-libitum. At four weeks old, they were equalized for weight and distributed into three dietary treatments (control, 10% and 15% unpeeled sweet potato meal as partial replacement for maize) each replicated four times with 15 birds per replicate; laid out in a completely randomized design. The birds were managed intensively throughout the experimental period until they attained 7 weeks of age. Data collected were subjected to one-way analysis of variance. Results revealed that the inclusion of unpeeled sweet potato meal up to 15% in diets of finisher broiler chickens did not significantly affect the growth performance indices, haematological parameters, carcass traits and most of the serum metabolites except albumin which showed significant variation and ranged from 1.35 g/dl (15% USPM) to 1.90 g/dl (control). Least significant cost (N129.73) per kg feed was recorded in birds fed diet containing 15% USPM relative to highest cost (N136. 63) per kg feed observed in birds fed control diet. Conclusively, incorporation of unpeeled sweet potato meal up to 15% in diet of finisher broiler chickens reduced cost per kg of broiler finisher diet and had no detrimental implications on growth performance, haematological parameters, serum metabolites and carcass traits in chickens.

“…Also, Tamir and Tsega () studying broilers supplemented with different levels of dried sweet potato leaves concluded that its inclusion in levels of up to 1% in the dry matter can be considered the optimal level of supplementation when birds are sold on the basis of live weight. These authors also mention that if the birds are to be sold gutted, the inclusion of up to 1.5% of dry matter can be economically viable as it enabled higher carcass yield components.…”

“…Recent research has highlighted the importance of the use of agro‐industrial residues (Giordani Junior et al., ; Volpato et al., ), which are abundant in Brazil due to the country's intensive agricultural production. Researchers from different countries have studied the effect of sweet potato vines in animal nutrition (Tamir and Tsega, ; Nguyen et al., ; Lochmann et al., ) as a means of not only reducing the environmental impact of the production chain, but also lowering the final cost of the product.…”

SummaryConventional feedstuffs in Brazil are expensive, which has led to the search for less conventional cheaper and locally available feedstuffs. Thus, this study was carried out to determine the dietary effect of dry sweet potato vines (SPV) on the performance and some carcass characteristics of rabbits. A total of twenty-seven weaned White New Zealand rabbits (14 male and 13 female) 35 days old with an average initial weight of 755 g were allocated into three treatments. Nine rabbits were assigned to each treatment in a completely randomized design. Three diets were formulated to similar protein and energy levels: 0SPV -diet without inclusion of dry sweet potato vines; 10SPV -diet with 10% alfalfa hay replaced by dry sweet potato vines; and 15SPV -diet with 15% of alfalfa hay replaced by dry sweet potato vines. The experiment lasted for 49 days during which data for feed intake and body weight were recorded. The daily feed intake ranged from 73.17 to 78.02 g; daily weight gain from 22.32 to 23.17 g; feed conversion ratio (FCR) from 3.16 to 3.49 and final live weight ranged from 1839.44 to 1880.55 g. None of the evaluated performance parameters as well as carcass weight, heart weight and percentages of fat and protein in meat were significantly affected by any of the tested dietary treatments. However, the liver weight was statistically lower in animals fed the diets containing 10% of SPV, mainly due to lower glucose content. Glycogen within the tissue, did not differ significantly among treatments. It was therefore concluded that up to 15% of SPV can successfully be included in the diet of rabbits as a cheaper replacement for alfalfa hay without adversely affecting performance.
