Effect of addition date molasses or/and ascorbic acid with/without feeding method in some productive performance of broiler chickens Ross 308

Abstract

This experiment was conducted determine the effect of dates molasses, ascorbic acid and feeding method on growth performance and carcass characteristics in broiler chickens. A total of 480 one day–old broilers Ross 308 were randomly allotted to 8 experimental groups in a complete randomized design. Basic treatments were divided initially at time of hatching, a- early feeding group which had a free access to water and diet from direct time of post hatching until 6 weeks, this group contained 240 chicks which distributed into 4 subgroups with 4 replicates/subgroups. The 1st subgroup was fed basal diet (control), the 2nd subgroup was fed basal diet plus 1000 ml of dates molasses/l of drinking water. The 3rd subgroup was fed basal diet plus 50 g of L-ascorbic acid/l of drinking water. The 4th subgroup was fed basal diet plus 1000 ml and 50 g of dates molasses and L-ascorbic acid, respectively / l of drinking water, b- late feeding group which had free access to water and diet after 12 hours from their reaching to farm until 6 weeks, this group was also contained 240 chicks which distributed into 4 subgroups and 4 replicates/subgroup with the same feed additives mentioned earlier.All the chickens were reared in the same environmental and management conditions. Growth performance (body weight, weight gain, feed intake, water consumption and feed conversion ratio) were determined on 3 and 6 weeks. Carcass traits (dressing percentage, breast, Thigh and femoral part, abdominal fat), factor of productive efficiency and mortality were assessed on 6 weeks. Growth performance was significantly (P<0.05) improved in the dates molasses and ascorbic acid in both early and late feeding treated broilers compared to the not supplemented control. Dates molasses in water increased the relative weight of dressing percentage, breast and abdominal fat as well as ascorbic acid increased the relative weight of thigh and femoral part. These data suggest that the dates molasses and ascorbic acid may improve growth performance in broiler chickens.

Effect of Trichoderma reesei Degraded Date Pits on Antioxidant Enzyme Activities and Biochemical Responses of Broiler Chickens

“…Furthermore, after COVID-19 outbreaks, shortage in global feed resources is apparent due to strong competition between animals and humans for grains and cereals; thus, improving the utilization of locally available resources is urgent in the present circumstances (1)(2)(3).…”

“…The increase in bioactive substances in DDP after treatment by T. reesei is of added value to agro-byproducts in view of improving the nutritive value as feedstuffs and extended their utilization as a growth promoter. Furthermore, after COVID-19 outbreaks, shortage in global feed resources is apparent due to strong competition between animals and humans for grains and cereals; thus, improving the utilization of locally available resources is urgent in the present circumstances ( 1 – 3 ).…”

“…Practical applications of agricultural wastes in poultry nutrition play an important role in replacing expensive ingredients and/or additives in their diet particularly after COVID-19 outbreaks in which an expected shortage of feed resources for animal nutrition may have occurred ( 1 – 3 ). Poultry are a valuable source of animal protein of high quality, and nutrition of poultry plays an essential role in controlling the balance of pro-oxidants and antioxidants and thus product quality and shelf life after harvest ( 4 ).…”

“…When subjected to degradation, enzymes secreted by T. reesei catalyze the degeneration of these substrates to simple sugars and enhance the degradation of plant cell walls. Degradation of date pits improves the chemical constituents and yields bioactive substances of added value for animal nutrition ( 1 – 3 ), and SSD is one of the reasonable methods to prepare degraded date pits (DDP) by using T. reesei .…”
