Effects of different proportions of dried cafeteria leftover inclusion in a concentrate mix on performance of growing pigs

Abstract

Article InformationAn experiment was conducted to evaluate the effect of inclusion of dried Cafeteria leftover (DCLO) at various levels in concentrate mix (CM) on feed intake, digestibility, average daily gain (ADG), feed conversion ratio (FCR), carcass characteristics, and economic benefits of weaned pigs at Haramaya university piggery. Twenty Yorkshire pigs with initial live weight of 19.89±0.297kg (mean±SE) were randomly assigned to four dietary treatments in a completely randomized block design each with five replicates. The experimental rations were sole CM (mixture of maize grain, wheat short, wheat bran, noug seed cake, soybean mill, vitamin premix and salt), replacement of the concentrate with DCLO at different proportions as (33%CM and 67% DCLO; 67% CM and 33% DCLO) and feeding with only sole DCLO. The mean feed intake ranged 1.6-1.82kg/day and ADG was 0.4-0.64kg/day. The least feed intake was for sole DCLO (P<0.05) and the highest for 67% CM:33%DCLO. The FCR (w/w) was lowest (P<0.05) for pigs fed 33% DCLO diet, and pigs fed 67% DCLO:33%CM achieved highest FCR. Crude protein digestibility did not differ between treatments, but DM, EE and CF digestibility increased with increasing level of DCLO in the diets. The mean carcass weight (43.7kg-57.02kg) was highest in 67% CM but lowest in sole DCLO. Back fat thickness (2.4cm-3.2cm (SEM=±0.03)) was lowest in sole CM but highest in sole DCLO. The highest and lowest (P<0.05) rib eye area (23.9 cm 2 -31.9cm 2 (SEM=±0.81)) were recorded for sole CM and sole DCLO, respectively. Cost of feed per kg weight gain was declined significantly (P<0.01) with increasing level of DCLO. Despite the lower production cost of sole DCLO groups, the pigs showed lower performance and this must have contributed to lowest net return of the groups. Thus, it is concluded that DCLO can replace the conventional concentrate mix up to 67% without adverse effect on pig performance.

Nutritional and Economical Evaluation of Inclusion of Hotels Leftover Food in Growing Lambs Rations

“…The highest (P<0.05) values were observed with animals fed ration contained 50% DLF (R3), followed that having 25% DLF (R2) compared with that of 0% DLF (R1, control ration). Amene et al (2016) showed that the digestibility of CP is not affected by the different levels of dried Cafeteria leftover that inclusion in the rations of growing pigs but the DM, CF and EE were increased with increasing levels of leftover in the dietary mix. While, Chae et al (2000) showed that the digestibility of CP and EE were increased with increasing the different levels of dried food waste in the diets of growing pigs.…”

“…Ration containing different levels of DCLO was economically feasible than that free from it respecting cost effective diet for pigs. Additionally, the economic return was more promising for pig fed 67% DCLO containing ration (Amene et al, 2016). Also, Hassanien et al (2020) reported that average daily cost, feed cost/ kg gain, daily profit (LE), relative daily profit and economic efficiency were improved by increasing DLF (20,40%) in crossbred cow calves' rations compared with control one (0%).…”

“…These results are in agreement with those recorded by Maeng et al(1997) who found that increasing substitution levels of fermented leftover foods in the diet for laying hens resulted in increasing feed intake. More recently, Amene et al (2016) found that daily feed intake in all treatments was consistently increased with increase in proportion of dried cafeteria leftover (DCLO) in the diet of growing pigs. The daily DMI was similar among the experimental treatments and likewise the amount of each DMI, TDN and DCPI per 1 kg gain was comparable among the dietary treatments (R1, R2 and R3).…”

“…The daily DMI was similar among the experimental treatments and likewise the amount of each DMI, TDN and DCPI per 1 kg gain was comparable among the dietary treatments (R1, R2 and R3). Amene et al (2016) showed that the final weight, total body weight gain (TBWG) and average daily gain (ADG) of the pigs were increased with increasing the levels of dried cafeteria leftover in their diet, and usually feed conversion ratio (FCR) was in reverse trend with ADG of the pigs. Hassanien et al (2020) showed that total body gain and average daily gain, TDN intake and DCP intake were significantly increased for crossbred cow calves fed ration contained 40% DLF compared to those fed control or 20% DLF.…”

Utilization of Leftover Food Collected from Hotels in Rations of Crossbred Cow Calves

“…Feeding value as TDN was higher significantly only with 40% DLF ration (R3) than that of control one (R1), however DCP value did not significant affected as increasing the level of DLF in rations. Amene et al (2016) showed that the digestibility of CP is not affected by the different levels of dried Cafeteria leftover that inclusion in the rations of growing pigs but the DM, CF and EE were improved with increasing levels of leftover in the dietary mix. While Chae et al (2000) showed that the digestibility of CP and EE were improved with increasing the different levels of dried food waste in the diets of growing pigs.…”
