Toxic effects among fumonisins B (FB), deoxynivalenol (DON) and zearalenone (ZEN) administered alone and combined were investigated in 84-day-old ducks during force-feeding. 75 male ducks, divided into five groups of 15 animals, received daily during the meal a capsule containing the desired among of toxin. Treated animals received dietary levels of toxins equivalent to 20 mg FB1+FB2/kg (FB), 5 mg DON/kg (DON), 0.5 mg ZEN/kg (ZEN) and 20, 5 and 0.5 mg/kg of FB, DON and ZEN (FBDONZEN), respectively. Control birds received capsules with no toxin. After 12 days, a decrease in body weight gain accompanied by an increase in the feed conversion ratio was observed in ducks exposed to FBDONZEN, whereas there was no effect on performances in ducks exposed to FB, DON and ZEN separately. No difference among groups was observed in relative organ weight, biochemistry, histopathology and several variables used to measure oxidative damage and testicular function. A sphinganine to sphingosine ratio of 0.32, 1.19 and 1.04, was measured in liver in controls and in ducks exposed to FB and FBDONZEN, respectively. Concentrations of FB1 in liver were 13.34 and 15.4 ng/g in ducks exposed to FB and FBDONZEN, respectively. Together ZEN and its metabolites were measured after enzymatic hydrolysis of the conjugated forms. Mean concentrations of α-zearalenol in liver were 0.82 and 0.54 ng/g in ducks exposed to ZEN and FBDONZEN, respectively. β-zearalenol was 2.3-fold less abundant than α-zearalenol, whereas ZEN was only found in trace amounts. In conclusion, this study suggests that decreased performance may occur in ducks exposed to a combination of FB, DON and ZEN, but does not reveal any other interaction between mycotoxins in any of the other variables measured.

Abstract This study aimed to evaluate the effect of zinc supplementation in various diets on the performance and health status of IPB-D2 chickens. Subsequently, about 180 one-week-old IPB-D2 chickens were used in the study and were fed the treatment diets for 12 weeks. Also, this study employed a completely randomised factorial design with six treatments and three replications of ten birds each. These treatment diets included A1, which contained nutrients based on SNI (2013) without Zn supplementation, A2 which is a combination of A1 and 60 ppm of Zinc, B1 which contained nutrients 5% higher than SNI without Zn supplementation, B2 which is a combination of B1 and 60 ppm Zinc, C1 which contains nutrients 10% higher than SNI without Zn supplementation, and lastly, C2 which is a combination of C1 and 60 ppm of Zinc. Furthermore, the data were analysed using ANOVA, and the parameters observed were the body weight, body weight gain, feed consumption, feed conversion ratio, blood profile and the villi surface area of the jejunum. Consequently, the results showed that C2 significantly (P<0.05) increased the body weight and body weight gain when fed to the finisher and grower chickens, respectively. More so, when the finisher chickens were fed the 10% SNI diet, there was an increased body weight gain and also a significantly (P<0.05) decreased feed conversion ratio. Furthermore, the addition of 60 ppm zinc increased haemoglobin significantly (P<0.05), whereas C2 decreased leukocytes significantly (P<0.05) in chicken blood. However, the treatments had no effect on feed consumption in the villi surface area of the jejunum. Therefore, the study concluded that supplementing the IPB-D2 chickens with 60 ppm zinc in a 10% SNI diet resulted in the best performance and health status.

Abstract Hatchery-cultured cutthroat trout Oncorhynchus clarkii fed some commercially available rainbow trout feeds display slow growth and increased mortality. Feed characteristics such as buoyancy and texture alter feed acceptance in some fish species, but their effects have not been adequately addressed in cutthroat trout. Therefore, the objective of this study was to examine whether feed structure and behavior preferences explain the decreased hatchery performance of juvenile cutthroat trout. To achieve this, we conducted two feeding trials in which we fed Westslope cutthroat trout O. clarkii lewisi and Snake River finespotted cutthroat trout O. clarkii behnkei a single diet formulation manufactured to display four different characteristics (floating, sinking, semimoist pellets, or a flake feed) and compared consumption, weight gain, and survival. In the first feeding trial, we stocked Westslope cutthroat trout (initial weight 11.3 g ± 0.5 g) at 20 fish/tank. We used two different sizes of tanks, with four replicate small tanks (54-L) and two replicate large tanks (96-L) per feed type. Results of the first trial demonstrated a significant effect of feed type but not tank size on weight gain of Westslope cutthroat trout with no interaction. Westslope cutthroat trout fed the flake feed gained less weight than did fish fed any of the other feed types. Feed conversion ratio was affected by both feed type and tank size with no interaction. In a second feeding trial, Snake River cutthroat trout (initial weight 19.5 g ± 0.5 g) were stocked at 20 fish/tank in 96-L tanks with four replicate tanks per feed type. Results of the second trial demonstrated that Snake River cutthroat trout fed the flake feed grew less, had higher feed conversion ratio, elevated hepatosomatic index, and reduced muscle ratio compared with fish fed the other feeds. Results demonstrate that flake feeds are not adequate for cutthroat trout at this life stage. However, additional research is needed to address other culture-related limitations because only minor differences between fish fed other feed types were detected.

Two trials were conducted on floor pens to evaluate the performance of broilers fed with diets contained different carbohydrases enzyme programs at different ages. Trial 1- The body weight gain (BWG) was affected by the Negative Control (NC) treatment (P<0.05). However, when the birds were fed with the NC diet + Amilase (AMY)+Xilanase (XYL), the BWG improved and reached the same level as the Positive Control (PC). Trial 2- The birds received enzymes supplementation in the total phase and others only in the grower phase.The ME reduction by 120 kcal/kg increased the feed conversion ratio (FCR) (P<0.05) when compared to PC and none of the enzyme programs was able to recover the performance. It can be concluded that it is possible to supplement with AMY during the role period of broiler chicken life or use an enzymatic program with AMY or AMY+XYL only in the grower phase.

One of the widespread spices is garlic which consumed by people of different parts of the world but its valuable growth promoting effect is not sufficiently studied in poultry. Growth promoting effect of garlic in broiler chickens was studied together with its carcass characteristics and blood parameters. Broilers were grouped into four: A (1%), B (2%), C (positive control) and D (negative control).  Aqueous extract of garlic (1% and 2%) was prepared by extraction and were administered with drinking water. A group (1%) shows best performance with regards to body weight gain rather than B (2%), positive and negative control. At the end of experiment (35th day), in A group, the live body weight, dressed weight, feed conversion ratio, liver, gizzard, heart, spleen, and pancreas were 1833.2±2.1g (P<0.05), 1229.7±1.9g (P<0.05), 1.63(P<0.05), 47.13±0.4g, 26.15±0.7g, 9.71±1.8g, 2.21±0.2g, 2.27±0.1g respectively. The mean Total Erythrocyte Count (TEC), Haemoglobin concentration (Hb) and Packed Cell volume (PCV) were 2.9± 0.1million/cm3,7.5g ± 0.2g, and 25.8 ± 0.6%, respectively. It is recommended that 1% aqueous extraction of garlic shows better growth and improved carcass qualities in broilers.

An experiment was conducted from 18th October, 2006 to 18th January, 2007 at IAAS Livestock Farm, Rampur, Chitwan to determine the substitution effects of soybean meal with brewer's dried grain (BDG) on the performance, economics and meat traits of swine production. Starter, grower and finisher diets were formulated containing 18, 16, and 14% CP respectively with 3000 Kcal/kg ME and adequately supplemented with required vitamins, minerals and amino acids. The treatments were: diet without brewer's dried grain -T1 (control diet), diet substituted with 10% brewer's dried grain-T2, diet substituted with 20% brewer's dried grain-T3, diet substituted with 30% brewer's dried grain-T4 and diet substituted with 35% brewer's dried grain-T5. Twenty weaned piglets having 7.37 to 7.94 kg live weight were housed in individual pens. Five piglets were randomly assigned to the five treatments following a randomized complete block design (RCBD) considering each individual as a replication. Fortnightly live weight, daily feed consumption, income over feed and pig cost, and different meat traits of pigs were recorded. The effect of replacing formulated diets with various level of brewer's dried grains on body weight gain was significant (p<0.01) with higher level of substitution resulting lower live-weight at the end of each of starter, grower and finisher diet period. The average body weight of piglets substituted with 35%BDG (27.00kg) and 30%BDG (39.75kg) were significantly lower (p<0.01) compared to the weight of piglets receiving 0% (65.75kg), 10% (64.25kg) and 20% (60.25kg) BDG replaced diets at the end of 3 months experimental period. A significant reduction (P<0.01) in average daily feed consumption were also recorded with increasing level of BDG in the diet. Better feed conversion ratio (FCR) was observed in T2 at early period which at finisher stage T3 diet resulted significantly better FCR which was at par with T1 and T2 diet fed group. However, T5 diet resulted the poorest feed conversion ratio of 5.26, 4.92 and 5.87 for starter, grower and finisher respectively. There was reduction in feed cost with different levels of BDG substitution in diet of pig. Highest income (in per cent) over expenditure (109.01%) was found in T2 followed by T1, T3, and T4. Lowest income over expenditure (-8.2%) was found in T5. Highest dressing percent (71.87%) was recorded in T1 and lowest (70%) in T5 diet fed group. Inclusion of 10-20% BDG seems most acceptable level of substitution of SBM. However, this result needs to be verified under farmer's management condition before recommendation.Key words: Brewer's dried grains; Swine performanceDOI: 10.3126/njst.v10i0.2820 Nepal Journal of Science and Technology Volume 10, 2009 December Page: 29-35

Considering the inherent attributes of processed African Yam bean meal (Sphenostylis stenocarpa), it's appropriate utilization for chicken diets may enhance performance of finisher broilers. The study was therefore carried out to determine the dietary substitution of soybean meal with processed African yam bean meal as protein source in the diets of finisher broilers. The Processed African yam bean meal was used to substitute soya bean meal at various levels to determine the best substitution that would give optimal performance in finisher broilers. The seeds of the African yam beans were soaked in water for 24 hours The soaked seeds were thereafter air dried for three days. The seeds were toasted for 35 minutes in a frying pan and milled using hammer mill. In the finisher feeding trial, the  substitutions were 20%, 40%, 60% and 80% processed African yam bean meal respectively. Each finisher diet was fed to a group of 30 broilers for 4 weeks using completely randomized design. Each treatment group was divided into 3 replicates of 10 broilers chicks each. The finisher broilerswere kept in pens in deep litter and given feed and water ad libitum. The parameters measured included initial body weight, final body weight, feed intake, body weight gain, feed conversion ratio, cost of production and carcass characteristics. The proximate composition of processed African yam bean meal showed that it contained 8.29% moisture, 91.71% Drymatter, 3.40% ash, 21.12% crude protein, 5% ether extract, 5.73% crude fiber and 56.4% nitrogen free extract. In the finisher feeding trial, the broiler group on 40% processed AYBM significantly (P<0.05) recorded higher body weight gain than the rest of the treatments possibly because of the proper substitution of soya bean meal with processed AYBM in their diets and it appeared that the finisher broilers could tolerate high levels of processed AYBM in their diets. The group on diet 2 (20% AYBM) and control diet recorded similar body weight gain (P>0.05) which were significantly (P<0.05) superior to the groups on diets 4 (60% AYBM) and 5(80% AYBM). The internal organs expressed as percent of the live weight were not affected by the treatments. Cost of production (cost/kg feed x feed conversion ratio) was lowest for diet 2 (N450.64) as against N480 for the control diet. The finisher broiler on diet 3 (40% AYBM) recorded the highest dressing out percentage of 78.78. The results of the trial have shown that processed African yam bean meal can be used to substitute soya bean mealin the diet up to 40% for optimum performance of the finisher broilers without affecting the body weight gain, feed intake, feed conversion ratio and carcass  characteristics as indicated in this study.

Increasing in ambient temperature inside the cage could lead to heat stress in broilers. This research was conducted to find out effects of heat stress on body weight gain, heterophile-lymphocite ratio and body temperature in chicken broiler. Twenty broilers aged 20 days (strain Cobb) were randomly divided into 2 groups. The first group was treated with no heat stress, the second one was caged in 33±1 0C temperature for 4 hours per day for 14 days. The results indicated that heat stress reduced body weight gain, increased body temperature, and changed behavior, but no effect on feed conversion ratio (FCR) and heterophile-lymphocyte ratio. It suggested that the heat stress caused detrimental effects on broiler chicken.
