The Cost

The Brazilian rabbit farming is in growing expansion, however, the cost with feeding are high. To ensure economic viability in the rabbit sector, research has been developed related to the use of alternative foods and co-products, aiming to reduce diet related costs. Therefore, the objective of this literature review was to approach the use of co-products and alternative foods in the diet of rabbits, focusing on their effect on animal performance. The period of publication of articles estimated for the searches was between 2010 and 2022. The availability of co-products and alternative foods is wide, however, when choosing these, factors such as source, quality and chemical-bromatological composition and region must be taken into accout. These factors are related to possible deleterious effects that can lead to reduced animal performance. Once chosen, it is expected that the dietary inclusion of such foods will promote better intestinal health of the animals, and consequently greater weight gain, lower feed conversion and influence the cost of production of the diet. It is conclude that there is a diversity of ingredients available to be included in diets for rabbits. However, it is necessary to carry out continuous studies to efficiently determine the inclusion levels per phase, as well as the identification of anti-nutritional factors and negative effects present in certain foods.

A study was conducted to determine the chemical composition and the nutritive value of boiled Christmas bush (Alchornea cordifolia) for starter broiler chickens. Dried Christmas bush fruits (Capsules + seed) were boiled for 30 minutes, sundried and ground into meal. The meal was analyzed for proximate composition and anti-nutritional factors and incorporated into broiler starter diet at 0%, 15%, 20% and 25% respectively. A total of 120 day old Marshall Strain broiler chicks were divided into 12 pens each containing 10 birds. Three pens were randomly assigned to each experimental diet. The boiled dried and ground Christmas bush (Alchornea cordifolia) fruit contained 19.9% crude protein and 4.7 mg/100 phytic acids which is an improvement when compared with raw Christmas bush fruits. Increase in inclusion level of boiled Christmas bush fruit in the diet caused a progressive reduction (p < 0.05) in final weight gain and feed intake of the birds. Birds on 15 and 20% BCBF had similar (p>0.05) feed conversion ration ratio with birds on control diet. The cost of feed per Kg weight gain and mortality were not significantly (p>0.05) different for all the treatments. Apart from Haemoglobin and serum phosphate, all other serum biochemical indices checked were not statistically (p>0.05) different among the treatment groups. It was concluded that boiling of Christmas bush fruits decreased the anti-nutritional factors and improved the nutritive value of the fruit but could not improve the performance of broiler starter chickens.

The purpose of this study was to evaluate the performance, carcass, meat and economic viability characteristics of pigs fed Brazilian coproducts of corn ethanol production. A total of 40 finishing pigs were subjected to four levels of distillers dried grains with solubles (DDGS; 0, 100, 200, or 300 g kg-1) for 28 days, and body weight, daily feed intake, daily weight gain and feed conversion were measured. After slaughter, the carcass yield, fat thickness, loin eye area, the depth and perimeter of the loin eye, and the pH and temperature at 45 min and 24 h post-mortem, along with the drip loss and color of the Longissimus lumborum were evaluated. The economic viability of the diets was calculated. The inclusion of DDGS showed a quadratic effect on daily feed intake over 0-14 days. Pigs fed with 300 g kg-1 of DDGS showed worse feed conversion than those fed the control diet over 0-7, 0-14 and 0-21 days. The a* color parameter of the meat decreased linearly with increasing DDGS concentration but the other carcass and meat characteristics were not affected. Inclusion of 184.1 g kg-1 of DDGS showed the best economic viability, considering the cost of weight gain. DDGS may be included in pig diets up to 200 g kg-1 without affecting the performance or carcass and meat characteristics, while 300 g kg-1 compromises feed conversion.

Food Consumed

The bioeconomics of feeding full-fat raw (RSB), toasted (TSB), cooked (CSB) soyabeans or defatted soyabean meal (SMB) to broiler chicks at starter and finisher phases was investigated using 240 Anak strain broiler chicks. At starter phase RSB diet significantly (P < 0.05) depressed average daily intake (ADI) only when compared with SMB diet. It also significantly (P <0.01) depressed daily weight gain (DWG): with values of RSB (20.1 gin), TSB (241 gm), CSB (24.0gm) and SMB (253 gm) as well as feed conversion ratio of RSB (3.03) TSB (2.63), CSB (2.49) and SMB (2.58). At finisher phase, the effects were not significant (P> .0.05) suggesting adaptation of the chick to RSB with time. SMB diet was almost twice as costly to produce as the other three diets. Cost of feed per unit of weight gained was highest (P < 0.05) with SMB diet followed by RSB diet while CSB and TSB diets were similar at starter phase. At finisher phase SMB diet still had significantly (P < 0.01) higher cost per kg weight gain than the RSB, TSB and CSB diets whose values were statistically the same. On gross margin, the use of SMB diet significantly (P < 0.01) resulted in the lowest values, followed by the RS B diet while the values of CSB and TSB diets remained similar and the highest at both phases. This underlines the importance of using cost of food consumed to obtain a unit of product as a basis for recommending feeds to farmers (alongside other nutritional factors).

The Cost

This study was designed to evaluate the effects of different Marshal breed broiler on hatching egg weights on hatching characteristics and post-hatch performances; and also to compare the cost of production of hatchlings to table size. A total of 900 hatching eggs (HE) from 40 weeks old parent stock were sorted, graded and purposively grouped on weight basis into small (<50g), medium (50-65g) and large (>65g) sizes (3 groups). Each group was allotted 300 eggs and replicated thrice, with each replicate having 100 eggs in a complete randomised design before incubation for 21 days. Candling of incubated eggs was done on day 18 on group basis and numbers of fertile eggs noted. The chicks were individually weighed and counted to determine hatchability, hatchling weight and cost of production. Thereafter, hatched chicks were allotted into the respective groups and replicated to determine the post-hatch performance. Each replicate has 45 chicks, intensively raised and were fed ad libitum with broiler starter mash for the first 4 weeks of life and broiler finisher mash from 4-8 weeks. Data generated include feed intake, final weight, mortality; weight gain, feed conversion ratio and unit cost of production of chicken were calculated. The data were analyzed by GLM of SAS and Duncan’s multiple-range test was used to separate significance of differences among treatment means at 5% significance level. The medium HE had the best fertility (93.00%), hatchability (95.67%) and cost of producing a chick (N 90.07) when compared with the small and large HEs. The large HE has the best results in terms of, final weight and weight gain, while medium HE has the best FCR, lowest mortality and least cost of production, which are significant at p< 0.05. It is therefore recommended poultry breeders and hatchery operators should consider the use of medium weight (50-65g) HEs in their operations, so as to cut down the production cost.

Considering the inherent attributes of cocoyam tuber meal (Xanthosoma Sagitifolium), its appropriate utilization for chicken diets may enhance performance of broiler chicken. This studywas therefore carried out to determine the nutritional evaluation of fermented cocoyam tuber meal as energy source in the diets of starter broilers production. The fermented cocoyam was used to replace maize at various levels to determine the best replacement would give optimal performance in starter broilers diets. One hundred and fifty 150 day old Agrited starter broilers were used for this experiment,. The proximate composition of fermented cocoyam tuber meal (FCYM) showed that it contained 19.5% moisture, 1.30% ash, 3.56% Crude protein, 5.30% crude fibre, 1.9% ether extract and 25.48% NFE. In the starter feeding trial, the fermented cocoyam was used to replace maize at levels of 25%, 50%, 75% and 100% respectively in the control diet. Each starter diet was fed to a group of 30 broilers chicks for four weeks using completely randomized design. Each treatment was divided into three replicates of 10 broiler chicks each. Parameters measured include initial body weight, final body weight, body weight gain, feed intake, feed conversion ratio and cost of production. In the starter feeding trial, the starter broilers on 25% FCYM compared favorably with those on the control diet (P>0.05) in terms of feed intake, feed conversion ratio and body weight gain and hence recorded the higher body weight gain. The cost per kg feed produced was N182.50 for the control diet and the lowest was diet 5 (100% FCYM) which was N82.74. The cost of production (cost/kg feed x feed conversion ratio) of starter broilers per kg body weight gain was lowest for diet 5 (100% FCYM) (N158.86), while the costliest was those on the control diet (N383.25). The results of the trial have shown that fermentation of cocoyam tuber meal for 4 days for formulating starter broiler diets was quite an effective method of processing because fermentation reduced the anti-nutrients content. It was concluded that fermented cocoyam tuber meal could be used in the diets of starter broilers up to 25% without affecting body weight gain, feed intake and feed conversion ratio as indicated in this study.

Abstract Two experiments were carried out to evaluate the nutritional composition and effect of different levels of inclusion of wafer-type biscuit waste (WW) in the diet of European quail on production performance, carcass yield and economic viability. In the metabolizability trial, WW showed 87.45% DM, 4,128.53 kcal/kg GE, 3,833.14 kcal/kg AME, 3,818.92 kcal/kg AMEn, 9.37% CP and 17% EE. The metabolizability coefficients of DM, GE, EE and CP were 93.20, 92.85, 93.01 and 47.16%, respectively. In the performance trial, feed intake decreased linearly (P<0.05) from 22 to 42 and from one to 42 days of age. Weight gain and feed conversion were not influenced (P>0.05) by WW inclusion. The WW inclusion levels did not influence (P>0.05) carcass yield. The diet with 20% inclusion of WW provided the best financial return. Wafer-type biscuit waste can be included up to the level of 20% in quail diets without compromising production performance, carcass yield or the economic viability of the activity.

The effects of replacing soybean meal with graded levels of fermented Senna obtusifolia seed meals (SOSM) on the growth performance of Clarias gariepinus were investigated. Five isonitrogenous (42% crude protein) and isocaloric (25.7% NFE) diets were formulated in which fermented replaced soybean meal (SBM) at 0% (SOSM0), 25% (SOSM25), 50% (SOSM50), 75% (SOSM75) and 100% (SOSM100) inclusion levels and a commercial feed (CmF) as the second control. Three hundred and sixty (360) fingerlings of (Clarias gariepinus) mean weight (2.85±0.01g) were stocked at (20) fish per tank volume in triplicate groups per treatment and fed 3% body weight twice a day of the experimental diets for 180 days. The feeding rate was adjusted after weighing. The water qualities were within range recommended for Clarias gariepinus. There were no significant differences (p> 0.05) in growth performance and nutrient utilization between the control groups and those fed the fermented SOSM diets at 25%. The commercial, 0% and 25% groups had the highest mean weight gain (279 to 280 g), significantly (P<0.05) superior to the groups that received the, 50%, 75% while the group that received 100% SOSM diet had the poorest mean weight gain (132.72g). Feed conversion ratios (FCR) of all treatments ranged from (1.75 to 2.18). These values increased slightly by increasing levels of fermented SOSM from 50 to 100%. The best FCR, 1.75± 0.02, recorded for fish fed 25% fermented SOSM indicated a superior level of utilization of the SOSM diet by the fish. There was no significant difference (P>0.05) in the protein intake among the group of fish fed 0 and 25%, but significant difference (P<0.05) occur in fish fed 50, 75 and 100% fermented SOSM respectively. Protein efficiency ratio (PER) exhibited significant differences (P<0.05) in all treatments except in the control diets that were not statistically different (P>0.05) from the fish fed the 25% fermented SOSM. The PER values increased among the experimental fish with respect to the quantity of total feed intake. There were no significant differences (P>0.05) in apparent net protein utilization (ANPU) among treatments CmF, 0% and 25%. The ANPU was highest in fish fed 0% fermented SOSM (91.6±0.04) while fish fed 75 and 100 % fermented SOSM in diets were 71.4±0.02 and 73.4±0.03 were the least. There was a significant (P<0.05) difference in the effect of the inclusion levels of fermented (SOSM) on final body carcass composition among treatments. This study showed that soybean meal can be substituted with fermented Senna obtusifolia seed meal up to 25% level in Clarias gariepinus diets without any negative effects on the growth and feed efficiency.

Effect Of Feeding

An experiment was conducted to evaluate the comparative effect of feeding sundried sweet potato and its whole meal to weaner rabbits. The proximate analysis conducted revealed that sundried sweet potato meal and whole sundried sweet potato meal samples were rather low in protein contents as compared to maize. Twenty seven Weaner rabbits averaging 0.35kg were randomly allotted to 3 treatment groups in a completely randomized design. Each treatment group was replicated 3 times. Sundried Sweet potato meal and its whole meal replaced maize at 20% inclusion level. Treatments 1, 2, and 3 contained the control, sundried sweet potato meal (SSPM) and whole sundried sweet potato meal (WSSPM) respectively at 20% levels of inclusion. The weaner rabbits were fed ad-libitum throughout the experimental period. Significant differences (p<0.05) were observed for growth performance of the rabbits in average daily weight gain, average daily feed intake and feed conversion ratio in the weaner rabbits using sundried sweet potato and its whole meal. The values of mean daily weight gain ranged from 16.33g in treatment 2 (SSPM) to 18.47g in treatment 1 (control). Treatment 3 (WSSPM) gave a higher value that is comparable (p>0.05) to that of the control diet but better (p<0.05) than that of treatment 3 (SSPM). The values of average daily feed intake also ranged from 43g in treatment 2 (SSPM) to 50g in treatment 1 (control). WSSPM was consumed more than (p<0.05) than the SSPM which however influenced the cost of total feed consumed. Moreover, the values of feed conversion ratio (FCR) ranged from 2.54 in treatment 3 (WSSPM) to 2.70 in treatment 1 (control). Significant differences (p<0.05) were also observed in bio-economics of production of weaner rabbits using the test diets. The cost per kg feed, cost of total feed consumed per rabbit, cost per kg weight gain and revenue of the rabbits fed the test diets were significantly lower than the control diet however, the cost per kg weight gain was lower (p<0.05) for treatment 3 (WSSPM). For gross margin, WSSPM value was significantly higher (p<0.05) than SSPM value and the control diet. It was concluded that whole sundried sweet potato meal can be a good feed ingredient in rabbit diet.

This study aimed to evaluate the effect of three herbage allowances (5, 10, and 15 kg dry matter [DM] 100-1 of body weight [BW]) for Brachiaria brizantha cv. Marandu pastures in a continuous grazing system on the morphological and nutritional characteristics of forage, animal performance, and economic viability in Nellore heifers. The total experimental area was 60 ha, divided into 12 paddocks of 5 ha each, with 4 paddocks per treatment. The experimental animals were Nellore heifers (260 in total), with average BW of 301.16 ± 9.12 kg, receiving 0.4 % BW in multiple supplements. We evaluated the production, structural characteristics, and nutritional value of the forage, productive performance, carcass characteristics, and economic viability of each allowance. There were significant effects for the production, st uctural characteristics, and nutritional value of the forage treatment. The proportions of leaves were 42.40, 38.20, and 30.88 % and the leaf:stem ratios were 1.22, 1.03, and 0.83 for the 5, 10, and 15 kg DM 100-1 BW herbage allowances, respectively. The average daily weight gain (mean 0.42, 0.75, and 0.63 kg daily-1) and stocking rate (3.35, 1.87, and 1.26 animal unit ha-1) had a significant effect for the 5, 10, and 15 kg DM 100-1 BW forage allowance, respectively. The herbage allowances were evaluated as being economically viable with a profit margin of 10.37, 23.65, and 14.43 % for the 5, 10, and 15 kg DM 100-1 BW allowances, respectively. The greatest pasture response was found in the 5 kg DM 100-1 BW allowance and was related to better nutritional values and morphological characteristics of the pasture and greater stoking rate and weight gain per area. The herbage allowance of 10 kg DM 100-1 BW be applied to obtain higher animal performance and better economic viability of heifers in B. brizantha cv. Marandu pastures in a continuous grazing method that are receiving protein-energy supplementation.

The objective of this work was to evaluate the performance of heifers fed sugarcane silages produced with and without additives. Thirty-two Holstein heifers were randomly assigned, in a block design, to evaluate rations (46% silage; 54% concentrate; 12% crude protein) containing silages treated with (fresh basis) urea (0.5%), sodium benzoate (0.1%) or Lactobacillus buchneri (3.64x10(5) cfu g-1 ). Inoculation with L. buchneri improved daily gain (1.24 vs. 0.94 kg day-1 ), and the addition of benzoate resulted in better feed conversion (7.6 vs. 9.4 kg of dry matter per kg of live weight), in relation to the untreated silage (control). Treatments did not affect dry matter intake (mean of 2.19% of live weight). Rations containing silages treated with benzoate or L. buchneri showed lower cost per kg of weight gain. Treatment with urea did not improve animal performance, but the cost per kg of weight gain was lower than that of the control ration.
