<p>Simplified diets are based on maximum incorporation of fodder and/or by-products into animal feed, thus minimizing the formulation and the costs. This study aimed to evaluate the possibility of feeding fattening rabbits with a simplified diet composed of only two agro-industrial by-products inexpensive and locally available: brewer’s grain and wheat bran. At weaning (35 days), 68 rabbits were divided into two identical groups (mean weight = 833 g) and housed in individual cages until slaughter (77 days). Each of the two groups (B0 and SF) was fed <em>ad libitum</em> either a commercial pelleted feed (control), or a simplified pelleted  experimental diet "SF" containing 72% wheat bran and 27% brewer’s grain. The feed conversion was within the standards and similar in the two groups (3.55 on average). The growth rate and feed intake of B0 group were 12% higher (P &lt;0.001) than that of the SF group (35.2g <em>vs</em> 31.2 and 128.3 <em>vs </em>113 g/d). The cold carcass yield and the carcass weight were respectively higher (P &lt;0.001) by 4 units and by 9% in the control group. The carcass of SF group was less fatty (perirenal fat: -23%, inguinal fat: -41% and scapular fat:-14%). The economic efficiency was 40% better for SF diet with almost 50 Algerian Dinar more benefit (/kg of meat).</p><p> </p>

Two hundred and twenty five day old straight run broiler chicks were utilized in completely randomized design to test the effect of restricting feed intake of four groups of chicks to 92.5% 85.0%, 77.5% and 70.0% of the unrestricted (control) group in the starter phase and following adlibitum feeding for all groups in the finisher phase. The treatments were simply designated as A, B, C, D and E. The starter phase in which the restriction was carried out lasted 28 days and the finisher phase 42 days. Parameters evaluated during the starter and finisher phases included; growth rate, feed conversion ration and mortality rate. Results show gain in weight among all groups while the group fed diet B and the control had comparable weight gain at the starter phase. The percentage weight difference between the control and each of the other dietary groups was: 4.4%, 8.4%, 8.6% and 10.4% for the treatments B, C, D and E respectively. Feed gain ration improved as the level of restriction became stricter. Following ad-libitum feeding of all grops at the finisher phase, the feed restricted groups at the starter phase voraciously increased their feed intake, thus, producing comparable performance values with the unrestricted (control) group in weight gain in the 8th week of the study. Although birds in all groups averaged more than 2000g final live weight in 10weeks, significant differences exist between groups that were fed diets C, D, and E that were restricted at the starter phase, an indication that complete compensatory growth was not obtainable. Feed gain ration improved for restricted groups. Mortality rate did not show any trend attributable to levels of feed restriction. This study shows that broiler chicks fed restricted levels of balanced diet at the starter phase but later fed ad-libitum at the finisher phase could attain a finished weight of about 2000g or more at a market age of 10 weeks (70 days) with an improvement in feed gain ration.

Background and Aim: The rearing of quails can have a stronger attraction for the breeders if we lower the cost prices by introducing by-products in their feed formulas. The aim of this study was to evaluate the effects of the partial substitution of soybean meal by apricot kernel cake (AKC) in the diet of quails, applied either sequentially or during all phases of rearing, on their growth performances, carcass characteristics, and meat physicochemical composition. Materials and Methods: A total of 600 one-day-old quails (Coturnix coturnix japonica), with equal sex ratio and weighing on average 7±0.2 g, were randomly distributed in one control group and three experimental groups, the latter being designed according to the rate of application of AKC in either sequential or non-sequential mode in different rearing phases. Each group was divided into five replicates of 30 quails, randomly distributed according to either substitution rate of soybean meal by the AKC (0%, 10%, 20%, or 30%) or farming phase. Results: The average daily gain from the 1st to 45th days (average daily gain1–45d) was found to be the highest (4.24 g/d/subject, p=0.021) for the 30% AKC-supplemented feed lot in either starter or finish incorporation (DFTAA), having an optimum final live weight of 193.4 g (p=0.028), a lowest feed conversion ratio of 3.08 (p=0.001), and a daily feed intake of 860 g (p=0.01). Carcass yield was recorded the highest (74.4%, p=0.02) with an optimum meat protein level (30.6%, p=0.024) and the lowest fat content (2.26%, p=0.001) for the same group as well. Conclusion: The partial substitution of soybean meal by AKC in the quails' fattening feeding, during the finishing phase and for all rearing phases, led to a better growth performance, a better carcass yield, and an improved chemical composition of meat.

This study investigated the effects of a Laetiporus sulphureus-fermented wheat bran (LS) supplementation on the microbiota and digesta characteristics of broiler chickens. Two hundred and forty male broilers (Ross 308) were randomly allocated into three groups fed with a corn–soybean-based diet (control), and the control diet being replaced with 5% wheat bran (WB) and 5% LS, respectively. Each group had four replicates and 20 birds per pen. Metagenomics analysis results of the ileum microbiota showed that, at the family level, the 5% LS groups had over 40% higher Lactobacillaceae compared to the control group in a mean difference comparison. Heat maps showed that, at the phylum level, the population of Firmicutes was higher and Proteobacteria was lower in the ileum of 5% LS compared to the control group. Results of the stack column plots of the top ten OTUs at the family level showed that a 5% LS and 5% WB supplementation altered the broiler microbiota distribution by increasing the relative abundance of Lactobacillaceae. Cecal microbiota analysis showed that the 5% LS-supplemented group had approximately 5% and 3% higher Veillonellaceae and Lactobacillaceae, respectively. Stack column plots of the top ten OTUs indicated that the distribution of cecal bacteria in each group was not markedly different. Both the ileum and cecum digesta in the 5% LS supplementation group had a slight and not significant elevation on the total VFA, while the pH values and ammonia nitrogen were significantly lowered compared to the control and 5% WB groups (p < 0.05). In addition, the 5% LS supplementation group had a significantly higher lactic acid concentration in both the ileum and cecum compared to the control and 5% WB groups (p < 0.05). In conclusion, a 5% LS supplementation could potentially enhance the feed conversion ratio and European Broiler Index (EBI) of broilers by elevating the family Lactobacillaceae and suppressing the phylum Proteobacteria’s population, thus creating changed intestinal environments that may potentially favor the growth and health of the broilers.

Background: The use of agro-industrial by-products is an alternative to enhance the performance of animals. Objective: To improve feed intake, digestibility, and live bodyweight changes for Abergelle sheep fed different mixtures prepared using short milled wheat and sesame seed cake mixtures. Methods: The experiment was designed using yearling male rams and was divided into four blocks based on initial live weight and assigned to each dietary feed randomly. The diets were prepared at a level of 0, 120, 240, and 360 gram dry matter base/day for diet1, diet2, diet3, and diet4, respectively, with a proportion of 65:35 (short milled wheat: sesame seed cake) combinations. Digestibility trial was conducted for 7 consecutive days following the 90 days feeding stage. Results: Total dry matter and nutrient intake were significant (P<0.001) in the order of diet4> diet3> diet2 level of supplementation than the control group (diet1). Feed conversion efficiency and final bodyweight gain were significant (P<0.01) for the supplemented groups. Apparent digestibility of crude protein was observed highest in diet4 (81.32) and lowest in diet1 (61.55). Similarly, dry matter and organic matter digestibility were significantly higher in diet4 (74.47, 76.38) and lowest in diet1 (58.71, 60.42), respectively. In general, supplementation with different levels of sesame seed cake and short milled wheat improves the biological performance of Abergelle sheep. Conclusion: The growth performance of rams can be realized supplementing with diets prepared using short milled wheat and sesame seed cake mixtures.

<em>The study was conducted in Urban Community of Niamey at modern and semi-modern farms provided an overview use of agro-industrial by-products in animal feed. Among 57 farms only 17 farms, including 10 beef farms, 2 sheep farms and 5 poultry farms were systematically surveyed. All farm managers are men. 60 and 33% are respectively officials at the level of poultry farms and ruminant farms. Farmers make up 25%, all of which own beef farms. There is also a predominance of adults, 60% at poultry level and 58.33% at ruminant farms. We note the use of a variety of agro-industrial by-products in animal feeds, in this case by-products derived from vegetable processing (wheat bran, exfoliated cotton cake) and animal processing (fish and fish meal ...). There are also some concentrates for poultry feed. Agribusiness by-products are increasingly used in urban livestock production but their valorization needs to be improved.</em>

Placing a ban on the use of antibiotics as additives for animal feed, had raised the producing risk, because of possibility for occurrence of many diseases in rearing piglets. One of alternative solutions is the use of probiotics as supplements, directly or in piglets feed. Aim of this study was to investigate the effects probiotic Enterococcus faecium DSM 7134 on the rearing piglets in the period from weaning to fattening start. This experiment included 500 piglets, divided in 2 groups, 250 piglets in experiment group (5 cycles with 50 piglets each) and 250 piglets (5 cycles with 50 piglets) in control group. Difference between experimental and control groups were in the way of feeding, experiment group had Enterococcus faecium DSM 7134 supplement and control was without. Influence of these probiotics was observed on the parameters: feed conversion ratio, daily gain increase and mortality. Piglets in the experiment group with probiotic Enterococcus faecium DSM 7134 in the ration showed lower feed conversion, higher daily growth increase and lower percentage of mortality, during this experiment. The difference between control and experimental group, for all parameters values, were established as statisticaly very significant (p<0.01) effect of the probiotic Enterococcus faecium DSM 7134 on rearing piglets in the period from weaning to the beginning of fattening.

Black soldier fly larvae (BSFL; Hermetia illucens) are known as an alternative feed for livestock, but their lack of polyunsaturated fatty acids (such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)) makes it less valuable. To overcome these problems, BSFL substrate (chicken feed) was fortified with squid liver oil (SLO) at five different concentrations (0, 2.5, 5, 10, and 20%). The growth rate, feed conversion, and nutritional content of BSFL were evaluated at day 15 of rearing. Of the five concentrations, SLO 5% showed the highest growth increase (25.82-fold) among the other treatments (20.63-22.98-fold; P<0.05). The fortification of SLO 5% did not result in differences in survival and feed conversion of larvae compared to larvae fed the control substrate. By rearing BSFL in a substrate containing SLO 5%, the lipid content of the larvae was 32% higher than that of larvae fed the control substrate (P<0.05). The accumulation of lipids was faster in the substrate containing SLO 5% (33.20% for 8 days) than in the control substrate (24.36% for 15 days). The control group of BSFL contained no DHA or EPA, but after rearing on the SLO 5% fortified substrate, the larvae contained DHA at an average level of 2.99 g/100 g lipid and EPA was 2.68 g/100 g lipid. Harvested larvae from SLO 5% treatment was within safe levels of Pb, Cd, As, and Hg (840, 370, 860, and 26.7 μg/kg, respectively), under the EU threshold for animal feed. Based on our results, it concluded that BSFL enriched with PUFAs, DHA and EPA can be considered as important nutritional components of animal feed without excessive heavy metals accumulation by feeding SLO in an appropriate amount.

This study was conducted with Thai broiler chicken (KKU 1) to investigate the effect of citric acid by-products from rice (CABR) on growth performance and villi histology. A total of 192 broiler chicks were subject to three dietary treatments, including 0% CABR, 3% and 6% of dry matter. Body weight gains, feed intake, feed conversion ratio, survival rate, and production index (body weight gain, feed intake, feed conversion ratio, survival rates, and productive index, respectively) were considered for growth performance evaluation. Villi height (µm), crypt depth (µm), and villi: crypt ratio were recorded for the villi histological measurement. The performance did not show a significant effect when compared with the control group during at ages ranging from 1 to 56 days. Villi histology indicate a significant effect on villi height (µm), crypt depth (µm), and villi: crypt of broiler chicks compared with the control group. Also, the use of 3% CABR caused a reduction microbial contamination in chicken fecal matter. In conclusion, supplementation of CABR had no negative effects on growth performance of Thai broiler chicken (KKU 1). Also, the addition of 3% CABR to the feed might help reduce fecal microbial contamination and affect the villi histology of Thai broiler chickens (KKU 1).

Low levels of added mannanoligosaccharides (MOS) in the feed for juvenile rainbow trout significantly promote growth rate, food conversion and overall culture results. Three levels of added MOS: 0.05%, 0.10% and 0.15% were incorporated in commercial pelleted feed and fed three and later two times per day. The experiment started with juveniles of 48?2.1 grams and lasted 90 days. The best growth result was obtained with the smallest (0.05%) MOS level, if compared to the control group and 0.1% and 0.15% MOS supplemented feed. The growth was improvedby11.5% with 0.05% MOS. The best feed conversion ratio (FCR) of 1.29 was found with 0.05% MOS supplement compared to 1.54 in the control group. FCR in 0.1% and 0.15% MOS treatments was 1.46, also significantly better than in the control group. The experiment shows that 0.05% MOS in trout feed is not fully successful in total elimination of salmonella colonies from fish intestine. But this is achieved with 0.1% MOS after only 30 days of experiment. The results of experiment point that smaller levels of MOS, if compared to previous research, are beneficial for rainbow trout juvenile culture.

Effect of feed supplementation to does grazed on naturally grown grasses during pre-partum on growth, reproduction and lactation performances of does and growth of the kids were investigated. Fifteen two-toothed and non-pregnant does of about one and half year of age constituted the experimental animals which were randomly allocated in the three groups of 5 and offered A) grazing ad libitum + l00g Mashkalai + 100g Wheat bran, B) grazing ad libitum + 50g Mashkalai + 50g Wheat bran and C) grazing ad libitum. The dry matter intake (DMI) between supplemented groups of A and B were almost similar (90 and 89g/kg w0.75/d respectively) and 12% higher than the control group C (80g/ kg w0.75/d). This DMI represent 4.6, 4.5 and 4.1% of live weight for group A, B and C, respectively. Does in treated group A consumed 30 and 62% more CP than group B and control group C, respectively. Similarly, group B consumed about 25% more CP than group C. There was no effect of grazing and supplementation before the pre-partum period on milk yield between treated group (A and B) and control group C (Av. 157 ml and 156 ml/d, respectively), rearing rate and growth of the suckling kids. Present study suggests that provision of grazing and supplementary feeding increases nutrients intake of does but appear to have no influence on milk yield. Higher prolificacy of Black Bengal goat may not bring any benefit unless milk production is increased.http://dx.doi.org/10.3329/bjas.v41i1.11975
