We have previously demonstrated that feeding chickens a diet containing high levels of the n-3 PUFA α-linolenic acid (ALA) significantly increases the content of the principal omega-3 long-chain polyunsaturated fatty acids, eicosapentaenoic acid and docosahexaenoic acid, in their meat and eggs. However, the effect of the diet on production characteristics of the birds has not been assessed. This study aimed to determine the effect of feeding male and female Cobb 500 broilers (n = 3840) a high ALA diet (containing 2.5% flaxseed oil) compared with a standard commercial Control diet (containing 2.5% tallow) on growth, feed conversion ratio and mortality until 6 weeks of age. As expected the dietary flaxseed oil significantly increased breast meat levels of omega-3 polyunsaturated fatty acids (~4-fold), with most eicosapentaenoic acid and docosahexaenoic acid being deposited in the phospholipid fraction. Both male and female birds fed the high ALA diet were significantly heavier at 6 weeks of age (77 g heavier in females, 87 g heavier in males). They also had a significantly (10%) lower feed conversion ratio, and a mortality rate that was not different from the Control diet across the 6-week feeding period. These findings indicate that a high ALA diet has the potential to enrich chicken breast meat with eicosapentaenoic acid and docosahexaenoic acid without loss of growth rate or feed efficiency, or increase in fat content of breast meat.

Deficit of conventional feed resources in meeting increased demand has led to hike in their prices culminating in soaring cost of livestock feed. This has necessitated the search for cheap and easily available alternatives. Pride of barbados seed which constitute a waste has potential of becoming a cheap and easily available feed resource. Performance and nutrient digestibility of dietary inclusion of raw pride of barbados seed meal was evaluated in an eight week feeding trial. Atotal of sixteen crossbred (Large White x Landrace) weaned pigs of eight weeks of age were weighed and allotted to four dietary treatments with four pigs each being a replicate in a completely randomized design. Diet 1 (control) was without raw pride of barbados seed meal while 5%, 10% and 15% of virgin raw pride of barbados were included in diets 2,3 and 4 respectively. Weekly weight gain, daily feed intake, feed conversion ratio and nutrient digestibility of raw pride of barbados seed meal was also determined. Results revealed a significant average final body weight of 16.75kg (diet 3) to 24.50kg (diet 4).The pigs fed 15% raw pride of barbados had the highest feed intake of 137.20kg in diet 4 while the lowest feed intake was obtained in pigs fed 10% (diet 3) inclusion level of raw pride of barbados. Pigs maintained on the control diet had the best feed conversion (7.60kg) while the pigs fed diet 3 had the lowest feed conversion ratio (8.93kg). Crude protein, ether extract and dry matter digestibility was highest at T4 (84.15%, 80.21% and 86.70%) respectively while the least values (68.71%, 65.75% and 71.10% was obtained in T2 and T3 respectively. This study concluded that 15% inclusion of raw pride of barbados in the diets of crossbred weaned pigs had no deleterious effect on performance and nutrient digestibility of pigs.

Abstract Appreciative dietary desires and fabrication of fish nourishment is vital to the progress, sustainability of aquaculture and for the advanced feed mill rehearsal. Organizing fish feed includes choosing the exact feed, using an acceptable feeding technique, work out the feed charge and ensuring the cost efficiency of fish farm. The purpose of our present study was to feed the fishes with four different feeds and assessment of growth performance by length weight relationships. The growth analysis was executed by measuring FCR and related indices in gift tilapia oreochromis niloticus. Four feed composition was selected without any chemical contamination. In the present study fishes were collected from the golden farm, Neyyattinkara, Thiruvananthapuram district, South India. Fishes were introduced into four different tanks of well oxygenated good quality water. In each experimental tank, 20 fishes were introduced. For each experimental container a specific feed was fixed from 4 different diets. Every day feed was given to the fishes. They were fed two times for the period of 3 months. They were maintained to assess their growth performance. Four types of feeds used for the present study were control diet, diet 1, diet 2 and diet 3. Length and weight were measured on every 15 days interval for growth estimation. Based on the length-weight data, growth analysis was carried out by calculating relative growth (RG), relative growth rate (RGR), specific growth rate (SGR), feed conversion ratio (FCR) and the Fulton’s condition factor. The results of mean length in diet3proved the highest length of 6.455±0.46cm and diet one contain lowest length of 5.03±0.68cm. Highest weight of 96.8 ± 0.37g was recorded in diet3 and lowest weight obtained for the control diet (3.645 ± 0.306 g). In growth analysis the relative growth of fish was estimated in diet 3 having high relative growth (11.91). Relative growth rate was elevated in diet 3(1.5597). The upper limit of specific growth rate was 1.9146% noticed in diet 3. The feed conversion ratio was maximum in diet 3 (58.06) and minimum in control diet (36). The highest k value in Fulton's condition factor was noticed in diet 3(88.32).All experimental results proved that live Azolla [D3] was a superior feed for the present trials.

One hundred and eighty 7-week-old laying quail were fed various diets over a 12-week period. The diets included a control diet (without essential oil mixture (EOM) or antibiotics (ANTs)), a basal diet including EOM (24 mg/kg feed), and a basal diet including an ANT (avilamycin, 10 mg/kg feed). Each treatment comprised 4 replications with 4 cages (15 quail per cage), amounting to 60 quail per treatment group. Diets (in mash form) and water were provided forad libitumconsumption. EOM consisted of 6 different essential oils derived from the following herbs: oregano (Origanumsp.), laurel leaf (Laurus nobilisL.), sage leaf (Salvia trilobaL.), myrtle leaf (Myrtus communis), fennel seeds (Foeniculum vulgare), and citrus peel (Citrussp.). In comparison with the control diet, adding supplements such as EOM and ANTs to the basal diet increased egg production in quail (P<0.001). However, egg production was similar between EOM and ANT treatment groups. Moreover, there were no differences between the treatment groups with regard to egg weight. Feed intake was not affected by EOM or ANT supplementation, whereas feed conversion ratio was significantly improved by EOM and ANT supplementation. Thus, we concluded that EOM has beneficial effects as a dietary supplement on egg production and feed conversion ratio.

An experiment was conduted to evaluate the effectiveness level of corn substituted by Morinda citrifolia leaf meal in broiler ration. The use of Morinda citrifolia leaf meal substituted for corn in ration is expected to improve feed conversion in broiler chickens and produce chicken meat that safe for consumption and free of chemical antibiotics residues . Completely Randomized Design (CRD) was used to analyze data obtained from this research. One hundred and sixty chicleas (7 days aged) divided into 5 (five) treatments with 4 (four) replications and each replication consisted of 8 (eight) chicleas. Ration of treatments were a negative control diet (R0), 1% Morinda citrifolia leaf meal (R1), 2% Morinda citrifolia leaf meal (R2), 3% Morinda citrifolia leaf meal (R3) and commersial ration (R4). All treatments rations were added a natural feed additive that consist of 0,125% Curcuma and.0,075% Turmeric meal. Measured parameters were feed intake, weight gain, feed conversion ratio, mortality, percentages of carcas and abdominal fat. Results showed that feed consumption, weight gain, and feed conversion ratio were significantly (p <0.05) influenced by treatments. Mortality, percentage of carcas and abdominal fat were not significantly (p >0.05) influenced by ration treatments. Mortality rates in chickens using a ration of treatment was 0%, while using the control diet 0,78% (1 bird). The counclusion showed that the substitution of 1-2% Morinda citrifolia leaf meal in ration has better performance compared to the control diet, with improvement of feed conversion ratio was 7.57 and 9.2% respectively was more efficient than the control diets

A 56 –day study was conducted to determine the growth performance and nutrient utilization of broiler chickens fed with two varieties (white and yellow) of cassava grit based diets. A total of 240 one day- old unsexed Arbor acre broiler chicks were assigned to eighty dietary treatments in a 2 x 4 factorial arrangement using completely randomized design. Diets were formulated to include two varieties of cassava, TME 419 (white) and TMS 01 1368 (yellow) at four inclusion levels (0, 25, 50 and 75%). Each treatment consisted of 30 birds and three replicates of 10 birds each. Data was collected on growth performance and nutrient digestibility at the end of the starter (4th week) and finisher (8th week) phases. At the starter phase, birds fed 50% white cassava grits diet had the highest (P < 0.05) final weight and weight gain (730.00 and 693.67g/bird). At the finisher phase, birds fed 50% yellow cassava grits diet had the highest (P < 0.05) final weight and weight gain (2235.60 and 1454.00g/bird), respectively while the least final weight and weight gain values (2008.80 and 1267.80g/birds) were obtained in birds fed the control diet. At the starter phase, birds fed 75% white cassava grits diet had the best (P < 0.05) feed conversion ratio of 2.18, while birds fed 25% yellow cassava grits diet as well as those fed the control diet had the least (P < 0.05) feed conversion ratio of 2.62 and 2.51 respectively. Birds fed 50% yellow as well as those fed 75% yellow cassava grits diets had the highest dry matter and crude fibre digestibility at the starter and finisher phases, respectively. In conclusion the substitution of maize with white cassava grits up to 50% level improved growth performance at the starter phase. However, either white or yellow cassava can be substituted for maize up to 75 % at the finishing phase.

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.

A study was conducted for eight weeks to determine the effects of raw and cooked mucuna seed meal (MSM) based diets on the performance and haematological characteristics of cross-bred weaned rabbits. Three experimental diets were formulated to contain: 0% MSM (control diet A), X raw MSM (diet B) and 20% cooked MSM (diet C). Twelve cross-bred weaned rabbits with mean initial live-weight of about 550 g were randomly assigned to three dietary treatments. The experimental design was completely randomized arrangement. The feed intakes (115.12, 114.44, 116.15g/day) and weight gains (17.19, 12.72, 14.28g/day) for diets A, B and C respectively were similar (P>0.05) for the three treatments. Rabbits fed the control diet A had the best (P<0.05) feed conversion ratio (6.68). The packed cell volume (PCV), haemoglobin (HB), red blood cell (RBC) and white blood cell (WBC) values obtained for the three treatments were not statistically different (P>0.05) from one another. The HB, RBC, WBC values of rabbits fed on 20% cooked MSM based diet had comparable values to those on the control diet. Based on the weight gain and the haematology, 20% cooked mucuna seed meal can be included in the diet of weaned rabbits.

Abstract The present study aimed to investigate the influence of supplementing beetroot (Beta vulgaris rubra) powder and its aqueous extract on the productive performance of growing geese. A total of 180 one-day-old goslings chicks of Chinese white geese were randomly distributed among five treatment groups containing three replicates of 12 birds each. Five experimental diets were formulated as follows: Control diet without supplementation (T1). In the second and third treatments, the beetroot extract was supplemented at 15, and 30 (ml/l) in drinking water; 15, and 30 (g/kg) beetroot powder (T4, T5) in basal diet respectively. Results indicated significant (p≤0.05) improvement in average body weight and weight gain from the 2nd to 12th week and total weight gain in treatment T2 and T4, which achieved the highest values compared to the control. As for feed intake, the T3 in the 6th week, T1 in the 8th week, and T2 in the 10th week were consumed a greater amount of feed compared to the other treatments, while no significant differences appeared in the 2, 4, and 12 weeks of age and in the cumulative period. No significant differences in the feed conversion ratio at age 2, 10, and 12 weeks, while the T5 in the 4th week, T2 in the 6th week, and the T4 in the 8th week, and the cumulative period showed the better feed conversion ratio compared to the other treatments. In conclusion, the supplementation of beetroot extract at 15, 30 (ml/l) or beetroot powder at 15, 30 (g/kg) improved the productive performance of growing geese.

The effect of dietary treatments on growth performance, haematological and biochemical indices of finisher broilers as well as economics of broiler production were determined in this experiment. Four broiler finisher diets were formulated with different inclusion levels of fermented cassava flour/blood mixture code-named “cassablood”. The control diet (T1) contained 0% cassablood, while diets 2, 3 and 4 contained 20%, 25% and 30%  cassablood respectively. 120 four weeks old Anak broiler chicken were randomly allocated the 4 diets with 30 birds per treatment replicated 3 times with ten 10 broilers per replicate in a completely randomized design (CRD).Treatment effects on final body weight, final weight gain, feed intake and feed conversion ratio were significant (P<0.05). Birds fed cassabloodbased diets compared favourably with the control diet. 20% cassablood inclusion performed equally with the control diet in feed intake, body weight gain and feed conversion ratio. All dietary groups also showed no significant differences (P>0.05) in most haematological and serum biochemical indices of broilers except in cholesterol, glucose and triglyceride contents which differed (P<0.05) significantly Similarly, chicken on 20% and 25% inclusion levels produced significantly (P < 0.05) higher economic gains in terms of feed cost per kilogram of broiler among all the treatments. Therefore, 20 - 25% cassablood dietary inclusion level was recommended in broiler diet for production and profit maximization.

Treatment with Panax ginseng has been reported to elicit various biological effects in both animal and human models. Among the reported effects on animal are protein synthesis and growth promoting ability. For a better understanding, the current experiment was conducted to evaluate the effect of oral administration of P. ginseng extracts (PGEs) on growth performance parameters of growing New Zealand White (NZW) rabbits. A total of 48 NZW male and female rabbits, with the average age of two months were used for the experiment, conducted in a Randomized Complete Block Design (RCBD). The rabbits were organized into 3 groups of 16 rabbits each (8 males and 8 females), on weight equalization basis and randomly assigned to 3 treatments: T1, T2 and T3, containing PGEs at 0.0, 200.0 and 400.0 mg/ml, respectively. Final body weight and total body weight gain of the male rabbits on T2 and T3 were significantly (p < 0.05) higher than those of male rabbits on T1, while feed conversion ratio for the male rabbits recorded a higher (p < 0.05) value in T1 than in T2 and T3, which were similar (p < 0.05). Trunk length and breast girth of the male rabbits were significantly (p < 0.05) higher in T3 than in T1 and T2. Feed intake pattern was similar among the male rabbits, but different between males and females. Significant (p < 0.05) differences were not observed in all parameters measured among female rabbits, but all experimental rabbits followed the same pattern of body weight gain. Oral administration of Panax ginseng extracts at 200 and 400 mg/ml levels enhanced feed conversion ratio in male NZW rabbits, thereby increasing body weight gain, trunk length and breast girth, while feed intake patterns slightly differed between the male and female growing rabbits.
