Evaluation of a rendered poultry mortality–soybean meal product as a supplemental protein source for pig diets123

The solid-state fermentation by effective microorganisms (containing photosynthetic bacteria, lactic acid bacteria, nitrogen-fixing bacteria, yeast and Bacillus sp.) improved the nutritive values of palm kernel meal (PKM). Increased crude protein (20.79%), nitrogen-free extract (40.07%) and gross energy (19.58%) were observed in fermented PKM (FPKM) relative to raw PKM while crude lipid (15.65%), crude fiber (36.45%) and ash (29.54%) were decreased. Replacement of soybean meal (SBM) with FPKM as a protein source was investigated for its effects in sex-reversed red tilapia (Oreochromis niloticus × O. mossambicus). The two-month-old fish (14.85 ± 0.28 g initial weight) were fed fish meal-SBM-based diets with replacement by FPKM at 25% (25FPKM), 50% (50FPKM), 75% (75FPKM) and 100% (100FPKM), while an FPKM-free diet (0FPKM) was used as a control. The five treatments, comprising triplicate cement ponds and forty fish each, were conducted in a recirculating system over 12 weeks. At the end of the feeding trial, fish fed the 50FPKM diet were superior in growth performance, while the feed utilization parameters were similar across all five treatments. Physiological adaptation of the protein-digesting (pepsin and trypsin) and lipid-digesting (lipase) enzymes was detected at all protein replacement levels (except for 25FPKM), as well as of the enzyme for cellulose digestion (cellulase), but not of the carbohydrate-digesting enzymes (amylase). Protein synthesis capacity in flesh was improved in fish fed the 50FPKM diet, while the quality of the main flesh proteins, actin and myosin, showed no significant differences across the five treatments. No differences in carcass composition and no negative effects on hematological parameters or liver histoarchitecture at the 50% replacement level of SBM by FPKM also support this alternative. Findings from the current study indicate the low-cost FPKM-containing diet for tilapia in comparison with control diet.

Castor Cake

This study aimed to evaluate the influence of the substitution of soybean meal (SM) by detoxified castor cake (DCC) by two alkaline products on intake, performance and on the growth curve of goat’s kids. 24 were used, Saanen goats (n=12) and Anglo Nubian (n=12), with initial body weight of 16.2±0.67 kg, initial age of 3 months and confined during the growth phase. The treatments consisted of three diets: a standard diet formulated with a traditional protein source, the soybean meal (SM); and test diets, which consisted of a protein source alternative, differing detoxification processes, on the basis of calcium hydroxide (Ca(OH)2) or sodium hydroxide (NaOH). The animals were distributed in a completely randomized design, in factorial 3 x 2 (diet SM, Ca(OH)2 DCC and NaOH DCC x Saanen and Anglo Nubian) totaling six sessions with four replicates each. The experimental period lasted 270 days. The non-linear models used were the Gompertz and Logistic. There was no effect (P < 0.05) of diets on the intake of nutrients, but there was no effect (P > 0.05) of breeds and interaction between both factors. The intake of DM during the phase of growth was greater for the goats fed with SM. There was no effect (P>0.05) of diets nor of the breeds in the ADG. Feed conversion was influenced (P < 0.05) by the diets, in which the goats fed diets with DCC presented better feed conversion. It has been observed that both models had good adjustments, with values numerically superior to 90%, however, the logistic model showed higher R2 and, at the same time, asymptotic index (AI). Despite the ADG be equal, the breeds presented absolute growth rate (AGR) vary over time, where the Saanen goats reached the peak first (181 days), with AGR of 0.14 kg day-1. However, even the goats Anglo Nubian reaching the highest peak late, the AGR was higher, around 0.16 kg day-1 higher than the Saanen. Both castor cake has the potential to replace the SM on a diet of goat’s kids during the growth phase. The mathematical model of Logistics estimates more accurately the growth of Saanen goats and Anglo Nubian, being that the rate of absolute growth is greatest in goats Anglo Nubian.

The study was conducted in the poultry field in the Animal Production Department/ College of Agriculture and Forestry/ University of Mosul, for the period from 18/ 2/ 2020 until 13/ 4/ 2020. The experiment aimed to study the effect of replacement different levels of sesame meal (SSM) as a protein source to replace soybean meal (SBM) on the productive performance and reproductive of laying quail, 360 quail birds (240 females and 120 males) were used, at the age of 49 days, distributed randomly into five treatments, each treatment with eight replicates, ( 9 birds in each replicate 6 females and 3 males). The treatments were as follows: the first was the control (0% SSM), the second, third, fourth, and the fifth replaced SSM by SBM with level (25, 50, 75 and 100%) respectively, feed and water was ad libitum during the trial period of 8 weeks. The results of the statistical analysis showed there is a significant statistical difference at a level (P≤0.05) in the fifth treatment (100% SSM) as compared to control and other treatments in total egg number, average egg weight, total egg mass, Hen day egg production percentage (% HD), feed intake, feed conversion ratio, fertility, and hatching percentage of total eggs, average weight of hatched chicks, and a significant increase in the embryo mortality. The results also showed a significant decrease at a level (P≤0.05) in the feed intake for the fourth treatment (75% SSM) compared to the control, while no significant differences were observed for the other treatments in all the studied traits. The results of this study showed the possibility of using sesame meal as a protein source at (75%) to replace soybean meal in laying quail bird diets.

AbstractTwo trials, one with 36 twin-suckling Chios ewes and the other with 32 twin-suckling Damascus goats, were conducted to study the effect of protein source (fish meal v. soya-bean meal) on the pre-weaning milk yield of the dams, and the growth performance of their offspring. The control (C) concentrate mixture was similar in both trials, using soya-bean meal (SBM) (195 kg/t) as a source of supplemental protein. In the experimental diet (FME) of the ewe trial, SBM was replaced completely by fish meal (FM) whereas in the goat trial (FMG) 83 kg of SBM were replaced by 50 kg FM. Dry matter (DM) and crude protein (CP) degradation of the three isonitrogenous mixtures were measured using nylon bags incubated in the rumens (2, 6, 16, 24 and 32 h) of three Damascus goats. There were no significant differences between mixtures for DM and CP effective degradability at 005 per h outflow rate. At 0·08 per h outflow rate however, lower degradability values were obtained with the FME than with the C diet. There were differences in the effective CP degradability of SBM and FM used in the ewe trial, but the FM used in the goat trial was of higher CP degradability and similar to that of SBM. Ewes on FM produced more milk than those on the control diet (C 3·44 v. FME 3·84 kg/day), whereas milk yield of goats was similar in the two treatments (C 3·87 v. FMG 3·82 kg/day). There were no differences between treatments for ewe milk fat (C 44 v. FME 43 g/kg) or protein concentration (C 54 v. FME 53 g/kg). Goats on fish meal (FMG) produced milk of higher protein (C 37 v. FMG 40 g/kg), but of similar fat (C 42 v. FMG 43 g/kg) concentration to those on the SBM (C) diet. With the exception of the better conversion (milk: gain ratio) efficiency (C 5·17 v. FME 4·44) of male lambs sucking ewes on the FM diet, no other differences were observed in the performance of lambs or kids. Lambs consumed less milk than kids (lambs: males 4·69, females 5·13; kids: males 6·63, females 6·98) per unit of weight gain.
