Background: Extruded products like pasta have gained popularity in today’s world and these products are generally high in starch, but low in dietary fiber and micronutrient content. Emphasizing this, an attempt was made to develop nutritious pasta fortified with finger millet, legume, carrot, mushroom and cauliflower leaf powder. Methods: Many initial trials were conducted in the laboratory to standardize that to what extent carrot, cauliflower leaves and mushroom powder could be fortified along with finger millet, and soy flour/green gram flour in semolina for formulation of value added macaronis. The sensory evaluation of developed macaronis was done by a panel of ten semi-trained judges using a 9-point hedonic scale. Developed macaronis were analyzed for proximate composition, copper, iron, zinc and â-carotene. Result: Three types of macaronis were developed. All sensory characteristics of experimental macaronis were liked moderately. Experimental macaronis were found nutritionally superior in terms of protein, mineral, crude fiber, calcium, iron, and â-carotene content.

Background: This study aims to determine the effects of blanching on the physicochemical characteristics of kinnow peel powder (KPP) and its suitability for cupcake formulation. Methods: The kinnow peels (KPs) were divided into five groups according to different blanching times at 95±5°C: 0 minutes (control), 2 minutes (T1), 4 minutes (T2), 6 minutes (T3) and 8 minutes (T4). All the blanched and control KPPs were examined for functional properties and proximate and organoleptic attributes. Result: The findings revealed that an increased blanching time affected the functional properties of KPP and varied significantly at a 5% significance level. The titratable acidity was reduced, with T4 exhibiting the lowest value (1.03±0.010). However, with the increased blanching time, the pH, bulk density, water absorption index and oil absorption capacity were also increased and reported as 6.32, 7.05 g/cc, 4.98 gm/gm and 2.04 gm/gm, respectively. The maximum protein content was observed in T4 (7.11 gm/100 gm) and its minimum values were recorded in crude fat (1.07±0.010 gm/100 gm), crude fibre (7.15±0.030 gm/100 gm), total mineral (3.54±0.035 gm/100 gm) and carbohydrates (70.79±0.11 gm/100 gm). An increase in the blanching time positively impacted the organoleptic attributes and reduced the bitter taste of the KPP (T4), boosting the overall acceptability of KPP. Hence, T4 was selected in cupcake formulation at 0% (TCC0), 10% (TCC1), 20% (TCC2), 30% (TCC3) and 40% (TCC4). It was noted that TCC2 might be used for cupcake formulation at the industrial level.

Background: With the ban on the use of antibiotics as feed additives and growth promoters in animal nutrition, livestock scientists are now shifting their attention towards natural and safe products like organic acids, probiotics, prebiotics and herbal growth promoters. Plants containing essential compounds can be a cost-effective means of improving efficiency of nutrient utilization and growth performance of animals. The medicinal properties of garlic may have beneficial effects on nutrient utilization and health of animals. However, very few studies have been reported whereby garlic has been fed to ruminants. Therefore, the present study was designed to investigate the effect of dietary inclusion of garlic (Allium sativum) on feed intake, growth performance and feed conversion efficiency in goat kids. Methods: Twelve kids of similar age were randomly allotted to two equal groups (n=6) on basis of body weight. All animals were maintained on common feeding regime consisting of required concentrate mixture and roughage as per requirement given by ICAR (2013). Kids in experimental group were supplemented with garlic @ 250 mg per kg body weight whereas; the control group was remaining unsupplemented. The study was conducted for 90 days. Animals were weighed fortnightly in the morning before offering feed and water. The data on growth rate in terms of body weight, average daily gain, feed intake and feed conversion efficiency were analysed as per standard procedures. Result: The results indicated that overall mean body weight and average dry matter intake were statistically (P greater than 0.05) similar in both the groups. No significant difference was observed in feed conversion efficiency between the treatment groups. The average daily gain was statistically similar in both the groups, but numerically 5.31 per cent increased ADG was observed in garlic fed group. From the results it can be deduced that the garlic supplementation improves average daily gain by 5.31%. However, it has no effect on feed intake and feed conversion efficiency of goat kids.

Background: Rice bran is the most valuable by-product of the rice milling operation. The FFA level rises immediately after milling and bran oil becomes hazardous for consumption owing to its lower pH, rancid flavor and soapy taste. Methods: A continuous-type infrared rice bran stabilizer was designed and process parameters such as moisture content, thickness, power density and treatment time were optimized for their impact on FFA content of bran, capacity and energy demand of the stabilizer using response surface methodologies. Under constant power density and moisture content, it has been confirmed that the capacity decreases with infrared exposure time. Result: The capacity was minimum (6.7 kg/h) at 0.5 cm thickness and 5 min exposer times, whereas it was maximum (40.2 kg/h) at 1 cm bed thickness and 3 min exposer time. The energy demand rose as the power density and time of exposure increased while the bed thickness and moisture content remained constant, whereas the FFA lowered nonlinearly as the power density and exposure time increased. FFA content was shown to be low at lower bed thickness and moisture content and to increase slowly as thickness and moisture content increased to 0.8 cm and 15% (w.b), respectively. However, when bed thickness and moisture level increase further, FFA content raised dramatically.

Background: The present study evaluated the bread bakery waste (BaW) containing ration on growth and nutrient utilization of meat quail. Methods: Three hundred straight run, day old quail chicks of same hatch were randomly divided into five treatment groups, namely T0 (maize-soya based basal ration, containing no BaW), T1 (5% maize in quail ration was replaced with BaW), T2 (containing 10% BaW as maize replacement), T3 (15% BaW as maize replacement) and T4 (20% BaW as maize substitute). All the diets formulated were isocaloric and isonitrogenous. Experimental trial lasts for 42 days. Different growth traits viz., feed intake (FI), body weight (BW), body weight gain (BWG), feed conversion ratio (FCR) and protein efficiency ratio (PER) was measured weekly. A metabolism trial of 4 days was carried out after 28 days of feeding trial and economics was also calculated. Result: Results revealed no adverse effect of replacing maize flakes with BaW up to 20% on different growth traits viz. weekly FI, BW, BWG, FCR and PER. The metabolizability of nutrients also remained statistically similar irrespective of different dietary treatments. But, Cost benefit ratio was better in T0 and T1 followed by T2 and T3 and was least in T4. It may be concluded that maize flakes can be safely replaced by BaW up to 15% in quail ration in an economical manner.

Some chemicals have been utilized as a feed additive and growth stimulator to boost poultry performance in recent decades. Cereals have been one of the most extensively utilized feed in the rearing period of broiler chickens but due to their highly price it can present an economic consequence and some limitations of their use, alternatives such as orange byproducts have been recommended. In the second point there is a large utilization of growth stimulants during the rearing period of broilers, but due to the adverse consequences of antibiotic resistance and the limitations of their use, alternatives such as probiotics, prebiotics, plant essential oils, essences and by-products have been recommended. Orange waste can be found in abundance in some parts of the world. Aldehydes, esters, terpenes, alcohols, ketones, carotenoids, nobiletin, pectin and bioflavonoids such as hesperidin and naringenin are among the volatile substances found in orange waste. The practical applications of orange by-products and pomace in chicken feeding are presented in this review paper. This review presented the effects of orange waste and by-products on chicken performance and carcass components.

Background: Dates are high nutritional value fruits. They are the basis of many traditional products and compose several oases by-products. Among these products, date paste represents a form of conservation widely practiced in Algeria to valorize common date’s surplus production for commercial purposes. Methods: First, microbiological analysis was carried out to isolate lactic acid bacteria (LAB) from date’s paste and microbial contaminants from both date fruit by-products according to standard microbiological methods before investigating the technological characteristics attributed to the isolated LAB. Second, the antimicrobial effect was evaluated through three different techniques. Result: Nine microbial contaminants were isolated from date paste and date extract, while eight LAB strains were isolated from date paste, which belong to the Streptococci and Leuconostoc strains. The SLM1 strain revealed a good acidifying power going up to 5.13 g/L of lactic acid within 6 hours of incubation compared to the other LAB strains. A moderate to strong antibacterial effect ranging up to a 20 mm zone of inhibition was revealed against bacterial contaminants. In decreasing order, the antifungal effect was significant against Penicillium sp, Aspergillus niger and A. flavus. The isolated lactic strains of streptococci could be good candidates for food preservation by extending the shelf life of foods and improving their nutraceutical and hygienic quality.

Background: Milking behaviour of milch cows has notable impacts on their production efficiency. The present investigation is designed to explore the relationship of temperament while milking with other milking behavioural features, milk yield and udder health in crossbred Jersey cows. Methods: The study was done on crossbred Jersey cows (N=94) kept at ICAR-National Dairy Research Institute, Eastern Regional Station, Kalyani, West Bengal. The cows’ temperament score (TS) was judged on 5 points scale (1-docile, 5-aggressive). Calmer cows (TS-1 and 2) covered relatively higher (75.24%) proportions and no observation had shown for TS-5. Result: The temperament score was positively associated (P less than 0.01) with stepping/milking (0.72), flight speed (0.43) and exit score (0.33), while it was negatively associated (P less than 0.01) with milk yield (-0.64), milking duration (-0.61) and milk flow rate (-0.65). It was concluded from the above study that milking behavioural features are directly correlated with each other and production parameters. Dairy animals of calmer temperament were significantly high-yielders. The temperament of dairy animals did not significantly impact udder health as assessed through MCMT and somatic cell counts in milk.

Background: Saum is a very important traditional food item of the Mizo society in Mizoram, North East India; but there is scanty scientific study and reports on Saum. The present study has been conducted to study and compare the prevalence of E. coli in Saum from three different storage places such as storage/keeping Saum under the sun (24-38°C) during hot part of the day, inside the refrigerator (3-4°C) and near the cooking fire (30-50°C) at home. Methods: The study was conducted from May, 2022 to November, 2022. A total of 105 Saum samples were collected from three different storage places comprising of 35 samples from each storage places and then analysed for the presence of foodborne pathogen E. coli and it’s virulence genes (stx1, stx2, elt, est genes) by conventional method and PCR. All the E. coli isolates were subjected to 12 different antibiotics for antimicrobial resistance pattern by disc diffusion method. Result: The overall prevalence of E. coli from 105 samples was 7.62% (8/105) comprising of 5.71% (2/35) from the storage place under the sun, 2.86% (1/35) from the refrigerator and 14.29% (5/35) near the cooking fire and no presence of virulence genes of E. coli was detected in the present study. The antimicrobial resistance pattern of all the 8 E. coli isolates showed the highest resistance to Cefazolin (100%) followed by Imipenem (37.5%). The present work will be a complementary contribution among Mizo society to know the best and safest storage places of Saum in regards to public health point of view.

Background: Algeria’s dairy sector is experiencing various obstacles, such as a high frequency of diseases in dairy farms, particularly mastitis. Nonetheless, there has been a scarcity of research on mastitis occurrence, notably in Algeria’s Western area. As a result, the purpose of this study was to investigate the prevalence of mastitis and its associated risk factors in Algeria’s northwest area. Methods: The study included 130 dairy cows from 17 farms. The California mastitis test (CMT) and visual inspection were used to determine the prevalence of subclinical and clinical mastitis. Result: The total cow-level prevalence was 68.50% (89/130), with clinical cases accounting for 3.10% (4/130) and subclinical cases accounting for 65.40% (85/130). The quarter-level prevalence of mastitis was 35.19% (183/520), with 3.08% (16/520) clinical cases and 32.11% (167/520) subclinical cases. The study found that parity, lactation stage and age were all significant intrinsic risk factors for mastitis (P less than 0.05). Additionally, cow cleanliness level, cleaning solution, wiping udder after washing and dry cow treatment were significant extrinsic risk factors linked with mastitis (P less than 0.05). Given the high prevalence of mastitis in this region, regular screening and treatment are crucial to minimize the risk of mastitis and enhance cow health.
