Experimental Diet

The physiological effects of Pekilo microfungus biomass (Paecilomyces varioti) grown in sulphite spent liquor solution was studied in pigs. Sixteen Finnish landrace gilts weighing about 22 kg were divided into two groups of eight animals each. The animals were fed a barley- and oat-based diet supplemented with vitamins and minerals. The soybean and fish meal mixture used as a protein supplement for the control group was replaced with Pekilo at a level of 13 % of the feed weight in the experimental diet used up till farrowing. The experimental diet used during lactation contained 15 % of Pekilo. The feed consumption and weight gain of the animals were recorded. The experiment lasted almost one year and included the growth, gestation and lactation periods of the sows. The weight gain of the piglets was observed. After weaning of the litter the sows were analysed for blood haemoglobin, haematocrit and white blood cell count, plasma glucose, serum bilirubin, ASAT, ALAT, urea, uric acid, allantoin, total protein and albumin/globulin ratio. The allantoin, uric acid and creatinine contents of a single urine sample were determined quantitatively, and the pH, glucose and protein contents semiquantitatively. The urine density was measured. There were no significant differences between the two groups with regard to weight gain, feed consumption, feed efficiency and reproductive performance. Serum urea and plasma glucose levels were significantly lower in the Pekilo-fed group than in the control group but were within the normal limits for swine. The serum allantoin level and the urine allantoin/creatinine ratio of the Pekilo group were significantly above the control group values. No differences were found between the two groups in the other blood and urine analyses. The use of Pekilo biomass as protein supplement in the diet of breeding sows was found to have no detrimental effects as assessed on the basis of weight gain, feed consumption, feed efficiency, reproductive performance and certain blood and urine parameters.

SUMMARYThe effects of Eimeria maxima or restricted pair-feeding on weight gain, plasma concentrations of protein, glucose, free fatty acids (FFA) and uric acid and liver glycogen were compared in immature fowl. Food intake/kg body weight and weight gain decreased during the acute phase of infection (days 5–7) while weight loss was prolonged for an extra day compared with pair-fed birds. During recovery, food intake/kg body weight of infected birds was greater than that of non-infected controls but there was no evidence for an increase in growth rate compared with controls when body weight was considered. Growth rate of pair-fed birds was greater than that of infected birds during recovery, indicating their better use of ingested food. Liver glycogen and plasma protein concentration were decreased during the acute phase of infection but the concentrations of plasma glucose, free fatty acid (FFA) and uric acid were not affected. In pair-fed birds liver glycogen was depleted, concentrations of plasma glucose and uric acid decreased and FFA increased, and these changes persisted for the remainder of the experiment. The findings are similar to those in birds whose food has been withheld and were probably due to the pattern of food intake imposed by the experimental protocol. It is concluded that the metabolic differences between infected and pair-fed birds are of doubtful significance.

This study was conducted under the Department of Physiology and Pharmacology to determine the effects of Neem and Nishyinda leaves supplementation on growth performance and GUT biosis in broilers. A total of 40 day old broiler chicks were divided into four groups A, B, C and D. Group A was considered as control, fed only with commercial broiler ration. Group B supplemented with formulation of 2 gm grinded Neem leaves, Group C with 2 gm grinded Nishyinda leaves and Group D with 1 gm grinded Neem leaves plus 1 gm grinded Nishyinda leaves per liter of water respectively. Observations were recorded for live body weight, weight gain, feed consumption, feed efficiency, hemato-biochemical parameters and GUT biosis specially the parasite of birds in six weeks. Body weights were increased significantly (p<0.05) in all treated groups in respect to the control and highest was recorded in combine Neem plus Nishyinda supplemented groups (Group D). No significant (p>0.05) differences were observed among the groups for PCV and TEC values. Hb content increased and ESR decreased significantly (p<0.05) with combine Neem plus Nishyinda supplemented group (Group D). The serum SGOT and SGPT levels were also decreased with the same kind of supplementation. In treatment group there was significantly decreased of parasitic eggs, but in case of control group no decrease of parasitic eggs. There was no significant pathological change in any internal organs of the broiler of treated groups. Best result was found in the group D. The present study reveals that combine supplementation of Neem plus Nishyinda gives better result over other groups in respect to body weight gain, feed conversion ratio, hemato-biochemical parameter and profitability without making any health hazard of the broilers.

The present study was aimed to investigate the dietary effect of different levels of turmeric (Curcuma longa) powder on the performance of broiler during summer (June-July), 2013. Four experimental rations designated as T0, T1, T2 and T3 having 0%, 0.5%, 1.0% and 1.5% Turmeric (Curcuma longa) powder were fed to 120 broiler chicks (Ross 308), randomly distributed into 12 replicates, so as to have 3 replicates per treatment and 10 chicks per replicate. Average weight gain, feed consumption, feed efficiency, dressing yield and survivability were used as criteria of response to feeding turmeric powder. Organs weight including heart, liver and gizzard were also recorded. The mean body weight gain and average feed efficiency (feed gain-1) per broiler significantly increased (P<0.01) by turmeric supplemented feed compared to control feed. The average feed consumption and survivability of broiler chick non- significantly (P>0.05) improved due to by turmeric supplementation in the diets. Inclusion of turmeric powder caused slightly increased the carcass traits of broiler chicks i.e., average weight of liver, heart and gizzard but the differences were non-significant (P>0.05). A significant decrease (P<0.01) in abdominal fat pad and significant increase (P<0.05) in dressing yield was observed in chickens fed the turmeric supplemented diets. The results of the present study suggest that the use of turmeric (Curcuma longa) powder as feed additive at a level of 0.5% enhances the growth performances and carcass yield of broiler chicks.SAARC J.

Potential Interactions

The performance of growing pigs fed 2 mg kg−1 of one of several Fusarium graminearum metabolites (sambucinol, 15-acetyldeoxynivalenol, 3-acetyldeoxynivalenol, culmorin, dihydroxycalonectrin) with and without 6 mg kg−1 deoxynivalenol (DON) was examined in three preliminary studies. The only significant effects (P < 0.05) were seen in feed consumption, weight gain and feed efficiency due to the presence of DON in the diet. In addition, the appearance and degree of folding of the esophageal portion of the stomach were also different between pigs fed the DON-free and DON-contaminated diets, though the degree of significance varied between trials. Some small differences were seen in growth and feed consumption for certain metabolites, notably sambucinol and culmorin, with and without DON, but they were not significant (P > 0.05). The data indicate that, at the dietary concentrations used, the fungal metabolites tested in combination with DON do not interact with DON in growing pigs to any marked degree.

A study was conducted to compare feed intake and growth rate of young dairy calves receiving two levels of triticale (27.5 and 55% of a complete ration) with calves receiving barley diets supplemented with urea or soybean meal. Effect of pelleting the 55% triticale diet was also examined. Each experimental diet was fed to 10 dairy calves (five bulls and five heifers) from birth. Experimental diets were fed free choice throughout. Triticale (1967 crop) at both levels reduced weight gain and feed intake relative to the control diets; however, there was little effect on feed efficiency. Low levels of ergot contamination of the triticale may have played a role in feed intake depression. Pelleting the 55% triticale diet resulted in reduced feed intake, similar weight gain and increased feed efficiency. Rations containing urea resulted in reduced rumen levels of isobutyric acid.

With the worldwide demand for tropical penaeid prawn increasing in recent decades, more research on shrimp culture methods is needed to enhance efficiency and profitability for shrimp farmers. The objective of this study was to develop a technique to boost the productivity, feed efficiency, and profitability of the giant tiger prawn (Penaeus monodon). To accomplish this, a novel culture setup was established in which two benthic organisms, a filamentous green alga (Chaetomorpha sp.) and a microsnail (Stenothyra sp.), were propagated together with P. monodon post-larvae during an early culture stage and then offered to shrimp as supplementary live feeds in intensive aquaculture ponds. For the experiment, shrimp post-larvae (density: approximately 33 individuals m-2) were cultured in outdoor concrete ponds (9 × 9 × 1.2 m) under either control (fed only artificial feed, n = 3) or experimental (fed artificial feed and benthic organisms, n = 3) conditions until they reached marketable size (15 weeks). Apparent green algae consumption was 6.81 kg (8.4% green alga to total feed consumption), whereas microsnail consumption was 1.96 kg (2.4% microsnail to total feed consumption). Compared with the control group of giant tiger prawn, the experimental group showed significantly higher productivity (total number of shrimp produced: 118%; total shrimp production: 133%), feed efficiency (feed conversion ratio of artificial shrimp feed: 89%), and profitability (shrimp sales: 139%; balance between shrimp sales and costs: 146%), while labor and financial costs were kept minimal. These results can be explained by the enhanced growth of shrimp at the early stages of culture. The techniques developed in this study will help to advance the efficiency of intensive aquaculture operations for giant tiger prawn and also improve profitability for shrimp farmers.

Methionine Supplementation

The purpose of this experiment was to know the effect of dl-methionine supplementation in feed on the body weight gain, feed consumption, and feed efficiency of broilers. The experiment was conducted at the Laboratory of Animal Husbandry Study Program, Agricultural Faculty, University of Timor, Kefamenanu from December 2019 to January 2020. The experiment used 80 fourteen-day broilers. The method used in this research was an experimental method with a completely randomized design (CRD) consisting of 4 treatments and 4 replications. The treatments given were: T0 (control feed), T1 (T0 + 0.30% dl-methionine), T2 (T0 + 0.50% dl-methionine), and T3 (T0 + 0.70% dl-methionine). The variables observed were body weight gain, feed consumption, and feed efficiency. The results of the experiment showed that the treatment significantly affected the body weight gain, feed consumption, and feed efficiency of broilers (P<0.05). It was concluded that commercial feed supplemented with dl-methionine by 0.70% increased the growth performance of broilers.

The reaction of the organism of broiler ducklings to the introduction of the probiotic additive "Lactobifadol" into the organism when reared up to 7 weeks of age was investigated. A positive effect was achieved to increase the live weight of the experimental poultry by 5.0 % (p <0.5), the average feed consumption per 1 kg of live weight gain in the group of broiler ducklings fed with Lactobifadol feed was 4.7 % less when compared to intact poultry. The dynamics of feed consumption per 1 kg of live weight gain in the first three weeks of rearing was descending, and from 4 weeks of age until the end of rearing, fodder consumption increased significantly. For 6 weeks of growing, the average consumption of compound feed per head per day in the control group of broiler ducklings was 157.5 g, in the experimental group – 158.5 g per 1 bird/day. The inclusion of "Lactobifadol" in the diet to a certain extent stimulates the processes of erythrocytopoiesis, providing, within the physiological norm, an increase in the level of hemoglobin and the number of leukocytes.

An experiment was conducted, with objective to determine the feed consumption, final live weight, weight gain, feed efficiency and economy in broiler chicken fed with locally available low protein based diets (20 percent CP in starter and 18 percent CP in finisher) supplemented with methionine, lysine and homeopathic medicine alfalfa. For this hundred fifty day-old birds of commercial broiler (Vencobb) were randomly assigned to five dietary treatments(10 chicks/treatment) and replicated three times in CRD with treatments composition of low protein based diets (LPB)  (T0), LPB+ 100g/100 met + 300g/100  lysine (T1), LPB + 200g/100 met +300g/100lysine (T2), LPB + Alfalfa 5ml/100 chicks 2 day in week with drinking water (T3) and LPB + Alfalfa 5ml/100 chicks 3 day in week with drinking water (T4). Synthetic methionine and lysine was used for supplementation of deficient amino acid. Same condition was applied in finisher diets of broiler chicken. The result showed that chicks fed with LPB in both starter and finisher diet had significantly (P<0.05) lower feed intake, final live weight , total weight gain, feed efficiency and income over feed and chicks cost (IOFCC) with compromising chicks fed with LPB with addition of methionine and lysine each and also homeopathic medicine alfalfa in starter and finisher period. Highest feed intake, final live weight, weight gain, feed efficiency was obtained with treatment (T1) followed by treatment (T2). However, positive growth response and better health status of chicks was also observed from supplementation of homeopathic medicine alfalfa with LPB and non-significant difference on Income Over Feed and Chicks Cost was obtained with treatment (T1). So, it was concluded that with supplemental methionine, lysine and alfalfa, the CP level of broiler chicks could be reduced up to 20 percent in starter and 18 percent in finisher diets without adverse effect on feed intake, final live weight, weight gain, feed efficiency and Income overfeed and chicks cost, provided under locally based feed ingredients.Int.

The post-molting performance of 360 female Japanese quails was assessed using five molting methods including feed restriction along with supplementation of dietary levels of aluminum sulfate (AlSO4) and zinc oxide (ZnO) with two concentrations of 0.15% and 0.3%. None of the parameters studied were positively influenced by a single molting method. Body weight gain and feed efficiency were positively affected by higher concentration of ZnO while feed consumption was positively influenced by higher concentration of AlSO4. Similarly high feed efficiency was attributed to higher concentrations of both ZnO and AlSO4. On other hand body weight gain and feed efficiency were negatively influenced by 0.15% ZnO while egg production was worst by 0.15% AlSO4. As each of the molting method had different influence on the tested parameters and none of them could apply individually with perspective of better performance therefore the combinational use of molting methods is recommended according to the focused parameter
