The effect of replacing fish meal (FM) with graded level of poultry visceral offal meal (PVOM) in five growers pullets’ diets were investigated in a 4 - weeks study using 200 Isa brown  pullets from 14 to 18 weeks of age. There were four replicate per test diet, with 10 birds per replicate. Diet A (control) contained 4% FM as the sole source of dietary animal protein. PVOM was included in diets B,C,D and E at the levels of 1.81,2.37,3.55 and 4.73% of the diets to supply 25, 50, 75 and 100% of animal protein supplied by 4% FM in the control diet A respectively. All the test diets were isocaloric (11.8MJ ME/kg) and isonitrogenous (16% CP). There was no significant effect (p>0.05) of replacing dietary FM with PVOM (on an equal protein basis) on the performance parameters measured. Birds fed on diets A,B,C,D and E had similar (p>0.05) mean daily weight gains of 14.16, 13.66, 14.65, 13.35 and 13.84g/b d respectively. The mean daily feed consumption values were 73.61, 73.27,73.88, 72.10 and 71.76g/b d for the birds on diets A,B,C,D and E respectively while similar mean feed conversion ratios of 5.21, 5.45,5.04, 5.42 and 5.21were also recorded for the birds on diet A,B,C,D and E respectively. It is concluded that PVOM could replace FM completely on an equal protein basics in grower pullets diets. Cost of feed per unit of weight gain was lower on the PVOM-based diet than on the FM-based diet.

A completely randomized design (CRD) was used with a total of 160 day-old commercial broiler chicks which were randomly assigned to four treatment groups with five replicates into 20 pens and brooded. Feed and water were provided ad libitum. From day old chick to 21 day, the broiler chicks were fed Diet 1 (5% fish meal and 25% soybean meal, 1: 5), Diet 2 (3% fish meal and 30% soybean meal, 1: 10) was served as control diet, Diet 3 (2% fish meal and 30% soybean meal, 1: 15) and Diet 4 (1.5% fish meal and 30% soybean meal, 1: 20). From day 22 onwards, the broiler chicks were fed finisher diet, Diet 1 (5% fish meal and 25% soybean meal, 1: 5), Diet 2 (2.6% fish meal and 26% soybean meal, 1: 10, serve as control diet, Diet 3 (1.8% fish meal and 27% soybean meal, 1: 15) and Diet 4 (1.3% fish meal and 26% soybean meal, 1: 20). Weekly performances and mortality are measured. By feeding FS5 diet (5% fish meal and 25% soybean meal), the heavier body weight, increased feed consumption and feed conversion ratio of broiler chicks was observed when compared to that of other treatment groups. Conclusively, it is obvious that the ratio of dietary fish meal to soybean meal 1: 5 (FS5) improved body weight but the lower feed efficiency of this diet should be considered in economical point of view.

An experiment was conducted to evaluate the replacement value of poultry visceral offal meal (PVOM) substituting for fish meal (FM) on an equal protein basis in the diets of unsexed Ross-strain broiler chickens from day-old to 8 weeks of age. One hundred and fifty birds were allotted in groups of 10 into 15 equidimensional floor pens with floor space of 0.189m2 per bird. There were three replicates per treatment diet, with 10 birds per pen serving as a replicate. Five treatment diets, each for the starter and finisher phases of 5 and 3-week duration respectively were fed ad libitum. Diet A (control) contained 8% FM which was gradually replaced with PVOM at 2,3,4,6,6,90 and 9.20% in diets B, C, D and E respectively for both phases. All the diets were isocaloric (ca 12MJ   ME/kg) for both phases and isonitrogenous with 23 and 20% dietary crude protein contents for the starter and finisher diets respectively. Feed intake and feed conversion rations (FCR) were similar (P >0.05) on all diets in support of complete substitution. However , weight gain for 8 weeks on the control diet was better (P <0.05) than those on FM/PVOM- and PVOM-diets whose weight gains were similar (P < 0.05). The mean feed intake values of 4.031, 3.936, 3.760, 3.870 and 3.715 kg/bird were obtained for birds receiving diets A,B,C,D and E respectively while the equivalent FCRs were 2.326, 2.352, 2.233, 2.326 and 2.340. The mean weight gains for birds on diets A,B,C,D and E for 8weeks were 1.824, 1.688, 1.689, 1.676 and 1.590 kg/bird respectively. The dressed weight and weight of back, drumsticks, things and wings were similar (P >0.05) for all diets in favour of complete substitution of FM with PVOM. Mean dressing percentages were 58.24 to 69.07% . It is concluded that PVOM could replace FM completely in broiler diets.

Protein Sources

A study was carried out to compare the use of blood meal and fish meal as protein sources in single phase feeding of broiler chickens.  Three isonitrogenious and isocaloric diets containing between 20.5 to 21.1 % CP and 3440 to 3454 kcal/kg ME were formulated. The control diet contained none of the animal protein sources while the other two diets contained blood meal and fish meal at 6%, respectively. After six weeks of straight feeding, data were collected on feed intake, weight gain and feed conversion ratio was calculated. Carcass characteristics and cost benefit were also calculated. The results indicated that birds fed fish meal based diet  consumed more feed (p< 0.05) than those on control diet,  while intake of those on blood meal based diet  was an interphase between the control and fish meal based diet groups. The birds fed fish meal based diet also recorded higher (p< 0.05) daily weight gain than those on control and blood meal based diets. Feed conversion ratio was better in the group fed fish meal based diet than those fed the control diet, but similar (p> 0.05) to the group fed the blood meal based diet. The dressing percentage of the birds was similar (p>0.05) in the control and blood meal based diet groups, but they were higher (p<0.05) than the fish meal based diet group. The neck, back, drumstick and head were significantly (p<0.05) higher in the control group than in the groups containing animal protein. Cost benefit analysis showed that feed cost and cost per kg weight gain were higher (p< 0.05) in fish meal based diet group than in control and blood meal based diet groups. Revenue per bird and gross margin were higher (p< 0.05) in the blood meal based diet group than in the control diet and fish meal based diet groups. In conclusion, fast growing broiler chickens for eatery houses can be better reared with a single diet of 21 % CP and 3440 kcal/kg ME using blood meal as a protein source.   Keywords: , , , , , ,

Dietary Treatments

There are well documented complications associated with the continuous use of antibiotics in the poultry industry. Over the past few decades, probiotics have emerged as viable alternatives to antibiotics; however, most of these candidate probiotic microorganisms have not been fully evaluated for their effectiveness as potential probiotics for poultry. Recent evaluation of a metagenome of broiler chickens in our laboratory revealed a prevalence of Lactobacillus reuteri (L. reuteri) and Actinobacteria class of bacteria in their gastrointestinal tract. In this study Lactobacillus reuteri and Streptomyces coelicolor (S. coelicolor) were selected as probiotic bacteria, encapsulated, and added into broiler feed at a concentration of 100 mg/kg of feed. In an 8-week study, 240 one day-old chicks were randomly assigned to four dietary treatments. Three dietary treatments contained two probiotic bacteria in three different proportions (L. reuteri and S. coelicolor individually at 100 ppm, and mixture of L. reuteri and S. coelicolor at 50 ppm each). The fourth treatment had no probiotic bacteria and it functioned as the control diet. L. reuteri and S. coelicolor were added to the feed by using wheat middlings as a carrier at a concentration of 100 ppm (100 mg/kg). Chickens fed diets containing L. reuteri and S. coelicolor mixture showed 2% improvement in body weight gain, 7% decrease in feed consumption, and 6–7% decrease in feed conversion ratios. This research suggests that L. reuteri and S. coelicolor have the potential to constitute probiotics in chickens combined or separately, depending on the desired selection of performance index.

ABSTRACT: To evaluate inclusion levels and residual effects of diets containing yeast extract (YE) plus blood plasma (BP) on the performance of 36 to 60-days old piglets, 105 piglets were used (8.75±0.72kg), and they were distributed under a randomized block experimental design with five treatments (control - 2.0% BP; 1.0% BP plus 0.0, 1.0, 2.0, or 3.0% YE), seven repetitions, and three animals per experimental unit. Piglets were given experimental diets from 36 to 49 days of age. From 50 to 60 day of age, all piglets received the same diet. No effects from treatments (P>0.10) were observed on the performance variables from 36 to 49 day of age. From 50 to 60 day of age, an effect was observed from YE levels on the daily feed consumption (P<0.03), daily weight gain (p<0.01), and final weight (P<0.06), which increased quadratically up to 1.67, 1.67, and 1.55% YE levels, respectively. Piglets which were fed with the diet containing 1.0% BP + 2.0% YE were observed to have better feed conversion ratios (P<0.01) as compared to the control diet (2.0% BP). As it provides a better residual effect, the inclusion of 1.67% yeast extract may replace 50% of blood plasma in 36 to 49-days old piglet diets.

The suitability of bacterial protein meal as a feed ingredient in silver fox diets was examined in an experiment comprising 72 juvenile silver foxes. Bacterial protein meal has a high content of tryptophan, which is the precursor for the neurotransmitter serotonin. The biological hypothesis on which this study was premised was that increased brain serotonin production reduces the fear response, which may lead to better welfare and performance through lower energy expenditure related to fear-induced defensive responses. The effect of substituting 15% fish meal with bacterial protein meal was measured by two behavioural tests, growth performance and fur quality, by comparison with a control diet and a diet supplemented with a high level of synthetic tryptophan. The welfare of the foxes fed the diet supplemented with synthetic tryptophan was considered to be improved, as they used shorter time to approach feed in the presence of a person; thus displayed less fear, than the other two groups after treatment. Weight gain of the foxes during 55 d did not differ among diets, and feed consumption was similar. Live grading of the foxes showed that the dietary treatments did not affect fur quality (P > 0.05). It is concluded that 15% bacterial protein meal can replace fish meal in dry silver fox diets and that a large supplement of tryptophan reduces fear of silver foxes kept in cages. Key words: Bacterial protein meal, tryptophan, serotonin, silver fox, welfare, performance

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

Experiment was carried out to determine performance of day old local fowls, fed supplemented plantain peels meal (PPM). The birds were arranged in completely randomized design having six birds per replicate and two treatments comprising one test diet and one control diet. At starter phase, all the parameters (body weight, body weight gain, feed intake and feed conversion ratio) measured were not significant (p>0.05). The birds on the test diet had average initial weight, 42.00g while that of the control had average weight, 43.75g and at 5 weeks of age average weights of 133.30g and 134.54g (p>0.05) ,respectively. At the finisher phase, all the parameters measured were not significant (p>0.5). The prices per kg of feed for the test and control diets were N93.05 and N95.05, respectively. Therefore, PPM inclusion fed at early stage of life of the birds enhanced performance at a lower cost.

It has been well established that animal protein performs better than plant protein in the growth and nutritive value of cultivable fish. By far the most suitable animal protein for incorporation into fish diets is fish meal. Fish meal is almost always made from marine fish, and can be based on the by-catches or a product of a specific fishery (De Silva and Anderson, 1995). Squilla species, a marine stomatopod generally called as mantis shrimp, is found in abundance along the Indian coast. The fine powder obtained from grinding the whole body of sun dried squilla species is known as squillameal, which has an excellent nutritive value. Taking this into consideration, it has been proposed to evaluate the suitability of incorporation of squilla meal as animal protein, in the traditional feed (rice bran and groundnut oil cake mixture) of Labeo rohita. For this purpose experiments have been conducted on the fingerlings (of an average weight of 5.33±0.13g) of L. rohita, for 90 days in the laboratory with 35% protein level traditional feed as control diet and 35%and 40% protein level feeds, formulated with squilla meal, as test diets. All the ingredients of these diets have been sieved, steam cooked after through mixing with water, pelletized with the help of a pellet mill and then dried in a hot air oven with blower at about 50o C. The dry pellets of these diets have been used to feed the experimental fingerlings of L. rohita to study the Absolute growth, Specific growth rate (S.G.R), Food conversion ratio (F.C.R), Protein efficiency ratio (P.E.R), and Apparent protein digestibility (A.P.D). The observations revealed that the performance of both the test diets formulated with squilla meal, is far superior to that of the control diet. However, from among the two formulated diets, the one with 35% of animal protein performed better in every respect. Proximate analyses of all the three diets and fish flesh have been carried out to evaluate the relative performance of the two animal protein incorporated artificial diets. The details are dealt in the present paper.

This study aims to determine the effect of fermented sago pulp in rations on performance (weight gain, feed consumption, feed conversion) and local sheep's income over feed cost (IOFC). This research was carried out in the community farms of Karang Rejo Village, Stabat District, Langkat Regency. This research started from March to June 2017. The design used was complete randomized design (RAL), with 4 treatment of 5 replications. Each replication consisted of 1 local sheep with an initial weight of 11.05 ± 0.56 kg. The treatment consisted of P1 (50% sago pulp without fermentation + forage), P2 (60% of sago pitch without fermentation + forage), P3 (50% fermented sago pulp + forage), and P4 (60% fermented sago pulp +). The observed variables were performance (body weight gain, feed consumption, feed conversion) and income over feed cost (IOFC). The results showed that the treatment of fermented sago pulp gave a very real effect (P <0.01) on daily weight gain. The mean of P1 = 33,05 g, P2 = 39,95 g, P3 = 46,57 g, P4 = 54,38g. The consumption of fermented sago pulp treatment has a real effect (P <0,01). With average P1 = 486,38 g, P2 = 548,68 g, P3 = 604,69 g, P4 = 671,11 gr. Against the conversion of fermented sago pulp fermentation treatment gave a real effect (P <0.05). With average P1 = 14.78, P2 = 13.90, P3 = 12.99, P4 = 12,49. IOFC the highest local sheep is Rp. 121.568 on treatment of P4 and IOFC lowest at treatment P1 equal to Rp.73.315. The conclusion of the research shows that the utilization of fermented sago pulp can increase body weight gain, feed consumption, local sheep feed conversion. P4 treatment economically has a better economic level than P1,P2 and P3.
