This study examined growth responses, health status and carcass yield of broiler chickens from 22 to 42 days of age provided with proprietary finished feeds (4 brands; P, Q, R & S) exposed to two storage conditions (lit or dark room) for four weeks. Four hundred and eighty chicks (802.7±14.3 g), at 21-day-old, were randomly allocated to eight groups of 60 chicks each (6 replicates; 10 birds each). Broiler chickens were fed one of the eight resultant diets from storage exercise for 21 d. Results revealed that performance of finishing broiler chickens were influenced by both the main and interaction effects of feed brands and storage condition. Chickens fed feeds stored in dark room gained 5.39% heavier weight with better FCR (5.07%) and higher (P<0.001) crude fat (2.97%), protein (2.36%), fibre (2.43%) and ash (3.89%) digestibilities compared to birds fed feeds stored in lit room. Chickens fed with feed R had higher (P<0.05) PCV, RBC, total protein, albumin, and uric acid. Duodenal and ileal villus height (VH) and villus to crypt ratio (VCR) were higher in broilers fed feed R stored in dark room, whereas jejunal VH and VCR were higher in birds fed feed Q stored in dark room. Salmonella and lactobacillus counts were greater in birds fed feeds R and S stored in lit room, respectively. Higher (P=0.008) dressed yield was obtained in broilers fed feed S stored in lit room. The study revealed that exposure of similar or different finished feeds to varying storage conditions would impart broiler's performance differently.

Extracts from eleven different plant species such as jute (Corchorus capsularisL.), cheerota (Swertia chiraitaHam.), chatim (Alstonia scholarisL.), mander (Erythrina variegata), bael (Aegle marmelosL.), marigold (Tagetes erecta), onion (Allium cepa), garlic (Allium sativumL.), neem (Azadiracta indica), lime (Citrus aurantifolia), and turmeric (Curcuma longaL.) were tested for antibacterial activity against potato soft rot bacteria,E. carotovorasubsp.carotovora (Ecc)P-138, underin vitroand storage conditions. Previously,EccP-138 was identified as the most aggressive soft rot bacterium in Bangladeshi potatoes. Of the 11 different plant extracts, only extracts from dried jute leaves and cheerota significantly inhibited growth ofEccP-138in vitro. Finally, both plant extracts were tested to control the soft rot disease of potato tuber under storage conditions. In a 22-week storage condition, the treated potatoes were significantly more protected against the soft rot infection than those of untreated samples in terms of infection rate and weight loss. The jute leaf extracts showed more pronounced inhibitory effects onEcc-138 growth both inin vitroand storage experiments.

Potato microtubers plays important role in seed potato production technology as it has great advantage of storage, transport and mechanization due to their little size and reduced weight. Dormancy in potato microtubers is very important and storage conditions as well as size of microtubers influences the dormancy in microtubers. Increasing size of the micro-tuber resulted in significant increase in the viability and sprouting ability of microtubers with reduced durations of dormancy and weight loss at the end of storage. Small microtubers are more vulnerable to storage damage. The larger microtubers lost moisture content more slowly and retained firmness longer when stored at 40C. Development of dormancy during storage strongly affected by the storage condition especially the temperature regime, the presence of light and the relative humidity. The dormancy duration was linearly and inversely correlated with the length of storage. Storage containers and conditions are also important for microtuber storage. Endogenous hormones ABA, ethylene, cyokinin and gibberllic acid play a significant role in tuber dormancy regulation.Microtubers with thick diameter which have passed more times in dormancy and have better functionality than small microtubers with less time in dormancy. Growth regulators like gibberellic acid, thiourea, gibberllic acid + thiourea, randite and carbon disulphide plays significant role in dormancy breaking of microtubers.

The objective of this study was to assess the carcass yield, organ weights, and gut morphology response to Vachellia tortilis inclusion in broilers. Unsexed 14-d-old Cobb500™ chicks were randomly assigned to six diets containing 0, 30, 60, 90, 120, and 150 g kg−1 dry matter of V. tortilis leaf meal. The slaughter weight (SW), dressed carcass weight (DCW), breast weight, thigh weight (TW), drumstick weight (DW), and internal organs were measured. Villus height (VH), crypt depth (CD), epithelial, submucosa, and muscularis thickness were taken. The apparent villus surface area (AVSA) and villus to crypt ratio were calculated. There was a linear decrease in SW and DCW (P < 0.05) with the increase of V. tortilis leaf meal. The SW and DCW decreased by 0.77 and 5.25 g for each g kg−1 increase in V. tortilis, respectively. The TW and DW showed no relationship with levels of V. tortilis leaf meal. The relative weight of gizzard, intestine, stomach, heart, and kidney increased linearly (P < 0.05) as levels of V. tortilis increased. The relative weight of the liver was not related to V. tortilis inclusion. The VH, AVSA, VH to CD ratio, as well as submucosa, muscularis, and epithelial thicknesses linearly increased as the V. tortilis inclusion level increased. There was no relationship between V. tortilis leaf meal inclusion and CD (P > 0.05). The increased morphological measurements suggest that leaf meal inclusion alters gut physiology and could influence the digestion and absorption of nutrients in broilers.

Wild pomegranate (Punica granatum L.) fruits were procured from Karsog area of Mandi district of Himachal Pradesh, India (1265 m above mean sea level). The arils extracted from the fruits were dehydrated in a solar tunnel (30-45°C) drier to prepare value added product Anardana. The developed product was packed in three different packaging materials viz. gunny bags, aluminium laminated pouches (ALP) and aluminium laminated pouches with vacuum (ALPV) and stored under ambient and refrigerated temperature for a period of 12 months so as to evaluate overall effect of storage period, storage condition and packaging material. After 12 months of storage period, higher retention of various quality characteristics like TSS, titratable acidity, ascorbic acid, total sugars, anthocyanins content, sensory characteristic scores with less increase in moisture content, NEB (non-enzymatic browning),HMF (hydroxymethyl furfural) and furfural content was observed in Anardana packed in ALPV followed by ALP and gunny bags. The changes in the quality characteristics of the Anardana were slower in refrigerated storage conditions as compared to ambient conditions.

Abstract Honey of stingless bee has a higher moisture content than bees. Long-term storage may cause fermentation processes to change the physicochemical properties and taste. Thus, the aim of this research was evaluation of the optimum storage condition on the quality of stingless bee honey. Stingless bee honey (Tetragonular larviceps) was contained in plastic bottle and kept at ambient temperature (30-35°C) and low temperature (4-8°C) for 0-45 days. Before and after storage honey were analyzed the physicochemical properties and sensory investigation for comparison of quality. The results showed that temperatures and storage times have affected on the reducing sugar content, pH, conductivity, color, moisture content with significant difference (p<0.05). While, temperatures and storage times have unaffected on the °Brix value (p>0.05). Additionally, the physicochemical properties of honey were according with previously quality report. The sensory investigation indicated that the smell natural flavor, consistency, taste and sourness were not significant difference (p>0.05). In contrast, the color and overall preference were significant difference (p<0.05). For honey quality, Thus, the honey might keep at 4-35°C for ≤45 day of this study.

Abstract Potential use of medium-chain fatty acids (MCFA), increased temperatures and exposure time may be implemented to mitigate biological hazards in premixes and feed ingredients. However, there are no data on how these strategies influence phytase stability. For Exp. 1, there were no four- and three-way interactions among premix type (PT), oil type (OT), storage condition (SC), and storage time (ST) for phytase stability (P &gt; 0.111). There were two-way interactions for PT × SC (P &lt; 0.001) and SC × ST (P &lt; 0.001). The OT did not affect phytase stability when premixes-containing phytase were added as either mineral oil (MO) or MCFA (P = 0.382). For Exp. 2, there was no interaction between PT and OT (P = 0.121). There were also no differences for phytase stability between vitamin premix (VP)- and vitamin trace mineral (VTM) premix-containing phytase were heated at 60 °C (P = 0.141) and between premixes-containing phytase were mixed with 1% MO added and 1% MCFA (P = 0.957). Therefore, the phytase was stable when mixed with both VP and VTM premix and stored at 22 °C with 28.4% relative humidity (RH). The phytase stability was dramatically decreased when the phytase was mixed with premixes and stored at 39.5 °C with 78.8% RH. Also, MCFA did not influence phytase degradation during storage up to 90 d and in the heat pulse process. The phytase activity was decreased by 20% after the premixes containing the phytase was heated at 60 °C for approximately 9.5 h. If both MCFA and heat pulse treatment have similar efficiency at neutralizing or reducing the target pathogen, the process of chemical treatment could become a more practical practice.

The objectives of this study were to understand how genotype, storage time, and storage conditions affect cooking time of beans and to indicate storage techniques that do not affect the cooking time. The grains were subjected to five different storage periods and six different storage conditions. The cooking time was estimated using the Mattson Cooker. The data were subjected to analysis of variance and a subsequent adjustment of simple linear regression for deployment of the interactions between the factors. Contrasts were used to determine the best levels of the factor storage condition. Genotype did not impact cooking time when the storage time and storage conditions were considered. Time and storage conditions affect the cooking time of beans in a dependent manner, but time of storage had the biggest influence. The best conditions for long-term storage of beans ensuring a smaller increase in cooking time is plastic storage at low temperatures. Thus, plastic freezer storage is a practical alternative for consumers.

The aim of our two-year study was to evaluate fruit decay and Monilinia fruit rot in three controlled atmospheres (CA), ultra-low oxygen (ULO) and traditional storage methods on apples for a duration of several months storage period. Four phytopathological treatments were studied under each storage condition: 1) 48 healthy fruit per unit, 2) 48 injured fruit per unit, 3) 47 healthy fruit and 1 brown rotted fruit per unit, and 4) 47 injured fruit and 1 brown rotted fruit per unit. Our results clearly demonstrated that fruit loss during storage is highly influenced by storage conditions and health status of the stored fruits. In the 2005 experiment, the lowest and largest fruit decay occurred under the ULO and traditional storage conditions, respectively (Table 1). The fruit decay was significantly different for the different storage methods. Fruit decay was fully suppressed in ULO storage except in the treatments of injured and injured + 1 brown rotted apple. Under CA and traditional storage conditions, when healthy fruit was stored, fruit decay was significantly lower compared with injured fruit including 1 brown rotted fruits. However, half of the fruit decay was caused by M. fructigena in CA store irrespective to phytopathogenic treatments. In 2006, results were not so consistent on cv. Idared but were not essentially different from the 2005 experiments.

Several studies revealed inconsistencies in recommended feed particle size for optimal growth and productive performance of rabbits. Information on the interaction effect of feed form and feed particle size on rabbit’s growth performance and gut morphology is thereby a growing concern. Hence, the growth response, carcass yield and intestinal villus morphology of thirty-six growing male rabbits of mixed breeds (Chinchilla × New Zealand White) weighing between 550-600g were determined using two feed forms (FF): pellets and crumbs of different particle sizes (PS): 1 and 2 mm. The rabbits were allotted on weight equalization basis to crumbs and pellets composed of 1 and 2 mm PS in a 2 × 2 factorial experimental layout and subjected to Completely Randomized Design. Nine (9) rabbits were assigned to each treatment made of three replicates of three rabbits each. The rabbits were maintained on concentrate diets ad libitum for 10 weeks. Two rabbits per replicate with representative mean live weight were selected for carcass evaluation at the 10th week and the remaining one was used for intestinal villus morphology. FF and PS significantly (P<0.05) influenced the cost/kg feed but did not influence the growth responses. Rabbits on 1mm PS feed had a higher (P<0.05) dressing percentage (65.61 %) than 2 mm. Also, rabbits fed crumbs containing 1 mm PS recorded the highest dressing percentage. Rabbits on 1mm PS feed had a higher (P<0.05) lamina propria depth (172.50 µm) and apical width (52.50 µm) of ileum. Significant (P<0.05) interaction effects were observed for lamina propria depth (LPD) and basal width with rabbits fed crumbs of 1 mm PS having the highest LPD. It was concluded that carcass yield of growing rabbits could be optimized by feeding pellets or crumbs of 1mm particle size.
