Performance, serum biochemical indices and crude protein utilisation by broiler chickens fed diets based on two varieties of cassava (Manihot esculenta Crantz) grits  I. Starter Phase

Effect of dietary inclusion of cassava grits (Manihot esculenta Crantz) from two cassava varieties TME 419 and TMS 01/1371 as replacement for maize on performance, serum biochemical indices and crude protein utilization of broiler chicks was investigated in a three-week trial with Abor Acre plus broiler chicks (n=210). In a completely randomized design, birds were allotted to seven treatments, each replicated thrice with 10 birds per replicate. Diet 1 comprised 50 % maize and 0 % cassava grits, diets 2, 3 and 4 had their respective maize content replaced at 25, 50 and 75 % with cassava grits from TMS 01/1371 while diets 5, 6 and 7 was replaced correspondingly with cassava grits from TME 419 at 25, 50 and 75 %, respectively for a duration of 21-day. Increased dietary cassava grits significantly lowered (P<0.05) weight gain and metabolizable crude protein of broiler chicks. Birds on diets 3, 4, 6 and 7 had similar weight gain, feed conversion ratio and metabolizable crude protein. Except for significantly increased (P<0.05) total protein and alkaline phosphatase due to interactions of cassava varieties and inclusion levels, effects of cassava varieties and inclusion levels on other serum indices were similar (P>0.05). Regression of metabolizable crude protein on graded cassava grit inclusion for both varieties were negative and significant (P<0.05) for TME 419 (R2 =0.355) and highly significant (P<0.01) for TMS 01/1371 (R2 =0.6639). Both graphs clearly depicted decreased metabolizable crude protein due to increased cassava grits in the diets. Increased dietary cassava grits of both varieties resulted in lowered metabolizable crude protein and serum indices with concomitant increased feed conversion ratio of broiler starter chicks.

Biochemical Indices

An experiment was conducted to determine the effect of nutritional supplement of comfrey symphytum leaves extract on the performance, haematological and serum biochemical indices of starter broilers. 200g of Comfrey symphytum leaves were squeezed in 1 litre of H2O with a juicer to produce Comfrey symphytum extract. The leaves extract was further mixed (diluted) in clean drinking water at the rate of 0ml/l of H2O, 25ml/l of H2O, 50ml/l of H20 and 75ml/l of H2O designated as T1, T3, T4 and T5. T2 was given conventional supplement (divertamin). Five groups of 30-day old chicks of Agritech breed were randomly assigned to one of the supplementary Comfrey symphytum leaves extract and the divertamin supplement for 28days. Each was subdivided into three replicates of 10 chicks each. The broiler chicks were fed normal broiler starter ration for all the groups. At the end of the 28days trial, performance indices result showed that mean final weight, mean weight changes, mean daily weight gain, mean daily feed intake and feed conversion ratio were not significantly affected (P>0.05). However, T4 (50ml per litre of H2O) and T5 (75ml/litre of H2O) gave better performance in terms of feed conversion ratio. The cost/kg of weight gain was cheaper at T4 and T5. All the haematological (Haemoglobin, packed cell volume, red blood cell and white blood cell) and serum biochemical indices (total protein, urea, creatinine, cholesterol and liver enzymes) did not show any significant treatment effect (P>0.05). It was concluded that Comfrey symphytum had no deleterious effect on starter broilers and its use as a nutritional supplement could improve performance at 50 - 75ml/l of H2O and reduce cost/kg of weight gain.

A total of 144 day-old Anak 2000 strain of broiler chicks were used in the study. A basal diet was formulated and supplemented at 0, 200, 400, 600 mg kg of MgSO4 to constitute four dietary treatments. The birds were randomly allotted to the four dietary treatment groups and replicated thrice (12 birds per replicate). The performance characteristics, rutrient digestion coefficients, Mg utilization coefficients and haematological and biochemical parameters of the birds were determined Feed conversion ratio, crude protein retention, Mg utilization and blood parameters were highest in birds fed diet containing 400mg kg MgSO4 There were significant (p<0.05) differences in the final body weight, weight gain, Feed Conversion Ratio (FCR), Protein Efficiency Ratio (PER) and crude protein retention Liver Mg content, Mg intake and excretion increased significantly in a dosage dependent manner. Nutrients digestibility increased significantly as Mg levels increased from 0 to 400mg though, digestibility coefficients of Mg were significantly (p>0.05) depressed across treatments. However, serum Mg, Mg digestibility coefficient and tissue Mg residue were similar across treatment groups. The results showed that inclusion of 400mg kg supplemental MgSO4 in practical broiler starter diets resulted in improved performance and nutrients digestibility of the birds.

This article describes a new idea about using Bifidobacteriumsp isolates as an alternative to antibiotic growth promoters, based on the ability of Bifidobacteriumsp isolates, which have the potential as a probiotic in laying hens. This study aims to prove that Bifobacteriumsp could improve production performance, including feed conversion ratio, feed efficiency, and nutrient intake (feed intake, crude protein intake, crude fiber intake, lipid intake, and organic matter). A total of 150 laying hens at 25 weeks of age were divided into three groups (P0: control, P1: 0.1% antibiotic growth promoters, P1: 0.05% Bifidobacterium spp. probiotic) and fed on a basal diet containing 2750 kcal/kg metabolizable energy and 18% crude protein for four weeks. The different supplementation to the basal diets showed significant differences (p<0.05) on feed conversion ratio, feed efficiency, feed intake, crude protein intake, crude fiber intake, lipid intake, and organic matter intake among the treatments. However, feed intake, feed conversion ratio, crude protein intake, crude fiber intake, lipid intake, and organic matter intake were lowest in the group fed with 0.5% of Bifidobacterium spp. The highest feed efficiency was obtained from the groups fed with 0.5% of Bifidobacterium spp, compared with the control and supplemented antibiotics growth promoters group. 0.5% of Bifidobacterium spp. supplementation to the diet of laying hens is beneficial for increasing feed efficiency and improving feed conversion ratio. The practical and theoretical significance of the results is that Bifidobacterium spp. can be used to improve production performance in laying hens.

The performance and nutrient retention of broilers fed raw (RMD), toasted (TMD), boiled (BMD), soaked and boiled (SMD) or no (NMD) Mucuna cochinchinensis seed diets at both starter and finisher phases were assessed using 400 broiler chicks. The birds were fed a common proprietary feed (Top Feed) until 2 weeks of age, followed by a treatment diet for 3 weeks of the starter period, then 5 weeks on the finisher diet. At the starter phase, RMD significantly (P < 0.05) decreased liveweight, daily weight gain, protein efficiency ratio and encouraged poorer feed conversion ratio and higher cost per kilogram weight gain when compared with other diets. TMD decreased (P < 0.05) only the protein efficiency ratio. RMD also decreased (P < 0.05) retention of dry matter (DM), crude protein (CP), crude fibre (CF) and energy while TMD decreased (P < 0.05) retention of only DM, CP, and energy. At the finisher phase, RMD also significantly (P < 0.05) decreased daily weight gain, protein efficiency ratio and feed conversion ratio and increased cost per kg weight gain, while TMD decreased (P < 0.05) only the protein efficiency ratio and feed conversion ratio. RMD again decreased (P < 0.05) retention of DM, CP, CF and energy, while TMD, as in the starter phase, again decreased (P < 0.05) retention of DM, CP and energy. On a cumulative basis, RMD adversely affected (P < 0.05) all the parameters under investigation. TMD affected (P < 0.05) only the feed conversion ratio, protein efficiency ratio and cost per kg weight gain. Boiling Mucuna cochinchinensis, therefore, encourages significantly better performance of chicks, higher nutrient retention and lower cost per kg weight gain than toasting, whereas soaking before boiling does not add any advantage to boiling alone.

This experiment studied the effect of phytase and processing (heat treatment, grind size) on performance and nutrient utilization of broilers fed diets from 1 to 21 d that included hardred spring (HRS) and durum wheat with three grind sizes (470, 560, 630 µm) with or without heat treatment (oven dry at 80°C for 15 h) before supplementation with phytase (Natuphos® 0 or 600 FTU kg-1). All 24 diets contained 0.5 g Avizyme 1302 kg-1 and were formulated (80% wheat, 20% basal diet) to supply nutrients necessary to meet the requirements of broiler chicks, except for a low level of nonphytate phosphorus (P, 2.7 g kg-1). The medium ground HRS-based diet produced significantly better feed conversion ratio (FCR) and body weights compared with the other two grind sizes. Heat treatment significantly improved feed conversion ratio and apparent metabolizable energy (AME), protein, and P digestibility of diets. It also significantly decreased feed intake, but produced no differences in 21 d body weight. Supplementation with phytase significantly improved AME, protein, and P digestibility of test diets. The AME of diets was influenced by wheat type, processing and grind size. Phytase increased N and P digestibility. Improvements in N and P digestibility by phytase and heat treatment were dependent on wheat type and grind size.The present results suggest an advantage of both phytase and xylanase in durum- and HRS-based diets. Heat processing destroyed endogenous phytase and xylanase in wheat-based diets, and increased the levels of soluble non-starch polysaccharides. Combined phytase, heat treatment, and grind size may synergistically improve N and P digestibility. Key words: Wheat source, grind size, heat treatment, phytase, digestibility, broiler

The effect of fermentation of cassava tuber followed by its gelatinization was evaluated as a method of processing cassava for use as source of energy in broiler diets. Peeled and unpeeled cassava tubers were separately fermented in water for 4 days, dried in the sun and then milled to produce fermented peeled and unpeeled cassava tuber meals, respectively. The dusty meals were then gelatinized by mixing with water in pots seated over fire at the rate of 1kg of cassava tuber meal to one litre of water and stirred until they gelatinized into fufu. The gelatinized pastes were then taken bit by bit and flattened on polythene sheets and dried in the sun. The resultant fermented and gelatinized peeled and unpeeled cassava tuber cakes were then milled to produce fermented and gelatinized unpeeled cassava tuber meal (UFGC), a brownish-looking non-dusty product and fermented and gelatinized peeled cassava tuber meal (PFGC), an ash-looking non-dusty product. Three broiler diets were made such that diet 1 (control) contained maize as source of energy, while in diets 2 and 3, the maize in the control diet was completed replaced with UFGC and PFGC, respectively, both in the starter and finisher diets. One hundred and twenty (120) broiler chicks were divided into 3 groups of 40 birds each and each group assigned to one of the diets, using completely randomized design, and fed for 4 weeks with the starter diets and finisher diets for another 4 weeks. At the starter phase, the UFGC diets gained significantly (P < 0.05) less weight and consequently had poorer feed conversion ratio. There were no significant differences in feed intake (P < 0.05). At the finisher phase, the group on UFGC gained significantly (P < 0.05) more body weight. The groups on cassava diet tended to consume less feed and so had better feed conversion ratio. There were no differences (P > 0.05) in dressed weights and weights of internal organs but the group on PFGC diet accumulated significantly (P < 0.05) more abdominal fat.

The Impact

This study was carried out to evaluate the impact of raw and cooked wild cocoyam (Caladium bicolor) on the performance of broiler chicks. Wild cocoyam corms were divided into two batches. One batch was ground raw and the other batch was cooked before grinding. Wild cocoyam meals so prepared were used to formulate 5 broiler starter diets at dietary inclusion levels of 0, 10 and 20% raw and cooked wild cocoyam respectively. 180 7-day-old Anak broiler chicks were randomly allotted to the five treatment diets in a Completely Randomized Design (CRD) and each group was further subdivided into three replicates of 12 birds. Measurements recorded included weight gain, feed intake, feed conversion and protein efficiency ratios and economics of production. Results shows significant (p<0.05) improvement in feed intake, weight gain, feed conversion ratio and PER of birds fed cooked wild cocoyam meals. Marked (p<0.05) reduction was however, obtained in feed intake and feed conversion ratio of birds fed raw wild cocoyam diets. There was no significant (p>0.05) difference between birds fed maize-based (control) and cooked wild cocoyam diets. Results of this experiment indicated that cooking improved the nutritive value of wild cocoyam since birds fed cooked wild cocoyam diets produced best results than those fed raw wild cocoyam meal and that starter broilers could tolerate up to 20% dietary inclusion level of cooked wild cocoyam without any deleterious effect. Economics of production showed that cooked wild cocoyam diets were more profitable as regards the cost of feed per kg weight gain (N) and thus cost savings (%).
