Effect of dietary supplementation of herbs on production performance and body temperature in broiler chickens - A Comparative Research
The present investigation was to determine the influence of dietary supplementation of Chrysopogon zizanioides, Mentha piperita, and Ocimum tenuiflorum on broiler production performance, body temperature, and intestinal histo-morphology. A total number of 160-day-old male broiler chickens (Cobb 400 strain) were employed in this investigation. A randomized design with four treatments and four replicates (each with ten birds) comprised the experiment. The baseline diet was referred to as control (T1). The basal diet plus 1% O. tenuiflorum, basal diet plus 1% M. piperita leaf powder, and basal diet plus 1% C. zizanioides root powder were given to the treatment groups T2, T3, and T4. Body weight gain, feed intake, feed conversion ratio, body temperature, offal weight, dressing percentage, and intestinal histo-morphometry (villi height, apical villi width, and crypt depth) were observed. Results from this study demonstrated that C. zizanioides root powder administration could increase cumulative body weight gain (2144 vs 2024, 2037, 1813g/bird), villous height (519 vs 464, 495, 322 µm), apical villous width (48 vs 34, 48, 33 µm), and crypt depth compared to control and other treatments. Ocimum tenuiflorum leaf powder-fed treatment group produced outcomes comparable to those of the control while having slightly higher feed intake than the control and other treatments. However, when compared to the control, the treatment-fed M. piperita leaf powder reduced body weight, feed consumption, villous height, apical villous width, and crypt depth. It might be determined that using 1% supplementation of C. zizanioides root powder will influence the effective broiler production performance and have healthier guts.
Perceived problems by dairy farmers in the adoption of milk value addition, entrepreneur practices and experts’ suggestions
The study was conducted to identify the problems in the adoption of value-added milk products. The present study was carried out in the Cuddalore district of Tamil Nadu from November to December 2022. Primary data was collected from 50 dairy farmers randomly. Problem confrontation index was employed for problem analysis, entrepreneur practices were documented by case study and expert suggestions were prioritized using Mean Weighted Score. The findings indicate that the unavailability of cold storage facilities, lack of credit facilities for starting milk value-added products enterprises and lack of training facilities on the preparation of milk products were major problems in the adoption of milk value-added products. Further, the age of the respondents had a negative influence on problems in the adoption of value-added milk products. The study also revealed that preparation of seasonal demand products, availing own funds for starting enterprises, obtaining technical information from institutions, displaying their products at local shops and supplying quality own-farm products were practised by the entrepreneur. Experts suggested better government policies for the establishment of mini storage facilities at the block level, participation of hands-on training on preparation of value-added milk products and better government policies to ensure remunerative prices of value-added milk products to smallholder farmers as MSP to overcome primary problems.
Synergistic Effect of Cinnamon Oil and Coated Sodium Butyrate on Gut Microbiota, Intestinal Morphology and Immune Response In Commercial Broilers
A biological trial was carried out with 216-day-old Vencobb 400 broiler chicks distributed to six experimental groups with six replicates, each replicate containing six chicks. The experimental groups were fed with control ration (T1), ration with antibiotic oxytetracycline (OTC) at 50 mg/kg (T2), ration with cinnamon oil (CO) at 250 mg per kg and coated sodium butyrate (CSB) either at 0.09 (T3) or 0.18 (T4) per cent levels and ration with CO at 500 mg per kg and CSB either at 0.09 (T5) or 0.18 (T6) per cent levels, lipid encapsulated sodium butyrate was used for the study. The trial was carried out in a deep litter pen for 35 days. The ileal Escherichia coli (5.52-5.71×105 vs. 6.85×106 cfu/g), total bacterial count (8.31-8.53×108 vs. 9.12×109 cfu/g) and Clostridium perfringens (3.90×103-4.23×104 vs. 5.00×105 cfu/g) count were reduced (P<0.01) on the addition of CO and CSB at either low or high levels of antibiotic while the Lactobacillus sp. count in ileal content was not influenced due to supplementation CO and CSB levels attempted or by the antibiotic. The jejunum villi height (1536.78 vs.1287.16 µm) was significantly (P<0.01) increased with the addition of CO and CSB at the levels tried or antibiotic but villi crypt depth and villi height: crypt depth ratio was not influenced by all CO and CSB levels or by the antibiotic. The inclusion of CO and CSB at different levels or antibiotics did not influence the Haemagglutination Inhibition titre against RD.
Identification of high-performance Chickpea (Cicer arietinum L.) landraces for heat tolerance using multi-trait genotype-ideotype distance index (MGIDI)
Heat is one of the most detrimental stress affecting chickpea (Cicer arietinum L.) yields during the reproductive stages. Multi-trait genotype-ideotype distance index (MGIDI) conducted to assess the performance of chickpea genotypes under heat stress conditions indicated strong correlations between MGIDI values, highlighting the impact of environmental conditions on chickpea performance. Advanced multivariate techniques were utilised, including Principal Component Analysis (PCA) and Factor Analysis (FA), to streamline trait selection and genotype identification. FA effectively reduced the dimensionality of the measured traits, simplifying interpretation and decision-making for breeders. The MGIDI emerged as a superior index compared to Heat Susceptibility Indexes (HSI) for selecting genotypes with desirable genetic gain for traits. MGIDI's ability to account for multicollinearity addressed a common issue in breeding experiments with correlated data. Genotype rankings based on the Multivariate Stability Trait Index (MSTI) using MGIDI identified stable genotypes, especially under heat stress conditions. Specific genotypes, including IG5999, IG5875, IG5851, IG 5868, IG5993, and ILC5588, exhibited notable stability and desirable traits. These genotypes hold potential as parents for future crossbreeding programs, aiming to create ideotypes that combine diverse favourable traits.
Impact of pinching on yield and economics aspects of bottle gourd [Lagenaria siceraria (Mol.) Standl.]
A research experiment entitled “Impact of pinching on yield and economics aspects of bottle gourd [Lagenaria siceraria (Mol.) Standl.]” was conducted at Punjab Agricultural University - Vegetable Research Farm, Ludhiana and Regional Research Station, Abohar during kharif season, 2022. The experimental were laid out in randomized block design with three replications having nine pinching treatments at different nodes. Pinching treatment was given at main branch and lateral branches of bottle gourd vines in each plot according to the assigned treatments. The results revealed that pinched plants on main branch and lateral branches at 6th node remarkably significantly increased polar diameter of fruit (14.75 cm), equatorial diameter of fruit (13.76 cm), fruit weight (587.91 g), number of fruits per vine (7.23), early fruit yield per plot (14.17 kg), fruit yield (42.50 kg plot-1 and 566.7 q ha-1), harvest duration (68.03 days), overall B: C ratio (3.70:1) and least number of days to fruit harvest (61.97 days). Based on the outcomes presented above, it can be inferred that pinching on main branch and lateral branches at 6th node demonstrates superior results concerning the comprehensive yield aspects in bottle gourd.
