A field experiment was carried out at Experimental Farm, in Al -kalahyn, Al -Hajer village, Qeft, Qena governorate, Egypt during 2017/2018 and 2018/2019 seasons, to evaluate of three planting methods (Drilling, broadcasting and furrows) and three irrigation intervals (21 , 28 and 35 days) on productivity of three wheat cultivars ( Sids 12 -Misr 2 and Giza 168 ).The results showed that exposing wheat plants to drought stress by increasing irrigation intervals significantly decrease (1000-grain weight, grains spike weight, number of spikes/m 2 , grain yield (ardab/fed) (argab = 150 Kg, fed= feddan= 4200 2 m² = 0.420 hectares = 1.037 acres), straw yield (ton/fed) and protein %).Irrigation intervals showed highly significant difference in for all characters studies.The highest value resulted from application irrigation intervals at 21 day compare with the other irrigation intervals.Planting methods significantly affected by all a previous characters.The highest value for all studies characters resulted from using drilling method.There were highly significant differences among wheat cultivars for all characters under study.The wheat cultivar sids-12 gave of the highest values of all traits compared to the other wheat cultivars used in both seasons.
An experiment was conducted to assess the palatability and nutritive value of Alpine pasture of Kashmir Valley by indicator method in Corriedale sheep of about 34.80 kg average body weight. Average DM intake was 3.1% of the body weight. DCP and TDN content of the pasture grass were 13.45 and 68.84%, respectively. Crude fibre, calcium and phosphorus content in the pasture grass was 19.0, 0.70 and 0.42%, respectively. DCP, TDN, Ca and P intake were 145.0, 743.0, 7.55 and 4.53 g/d/animal, respectively. It was concluded that the nutrients provided by the pasture grass were sufficient to support a daily average gain of 100–150 g in the grazing sheep on that pasture.
A field study was conducted in nine villages, three each from Kupwara, Handwara and Karnah Tehsils of Kupwara district, to find out the nutritional value of feeds and fodders, existing feeding practices and nutritional status of dairy cattle. Data was collected from the fifteen farm families from each of the nine were randomly selected through a common questionnaire. All the farmers were found to add the basal diet(paddy straw, rice bran and wheat bran) with salt (NaCl)) and none of the farmers used a mineral supplement with the diet. The mean values of daily dry matter intake (DMI) for lactating cows was 19.61 and 43.93% above the estimated feed intake accordingto the feeding standards (FS) for Kupwara and Handwara tehsils The DMI of dry cows was 41.40 and 37.21% above the DMI stated in the FS requirements. According to the live body weight of heifers, the daily DMI was observed to be 22.90, 46.78 and 6.80% above DMI requirements in the Kupwara, Handwara and Karnah tehsils, respectively. The daily digestible crude protein (DCP) intake in case of lactating cows was 12.65 and 38.10% above their requirement for Kupwara and Handwara tehsils. The dry cows has a DCP intake that was 19.81 and 19.94% above FS requirements in Kupwara and Handwara tehsils. Heifer daily DCP intake was 10.24 and 80.16% below FS requirements in Kupwara and Karnah tehsils, respectively The daily intake of DCP for calves was 29.5, 29.6 and 78.4 % below FS requirements in the respective tehsils. The daily intake of total digestible nutrients (TDN) were above FS requirements by 36.70, 55.9 and 7.6% for lactating cows; 51.10, 48.49 and 11.65% for dry cows; 45.85, 60.0 and 18.54% for heifers; 2.70, 14.7 and 11.7% for calves in the respective tehsils. The milk urea nitrogen concentration of the lactating cows were 18.55±0.74, 21.29±1.31 and 16.87±1.41 mg/dl for the respective tehsils. It was concluded that most of the farmers rear non-descript indigenous cattle of low body weight potentially to a general trend of under feeding protein in calves and sometimes growing heifers, which limits milk production. The genetic potential of the dairy cattle, nutrient imbalance in the diet and farmer awareness of balanced diets are also a potential problem.
The study aimed to evaluate the feed intake and growth performance of the local Kashmir merino lambs grazing on the sub-alpine pastures of the Kashmir valley in 2 seasons (summer and autumn). Kashmir merino male weaner lambs (50), 25 in each season were selected for the experiment. A 10-day digestion trial in each season was conducted by the indirect indicator method with chromium oxide as external indicator. Apparent digestibility of nutrients was higher in summer than in autumn. Feed and nutrient intakes (DMI, DMI/kg, MEI and CPI) were higher in summer than in autumn. Average daily gain was slightly more in summer (41 g/day) than in autumn (30 g/day) and animals suffered serious liveweight loss in the last two fortnights of autumn. Results indicated that sub-alpine pastures of Kashmir valley did not provide sufficient nutrients to sustain healthy sheep production thus necessitating supplementation.
Abstract Our study, the spring cultivar of the yellow corn crop was adopted in the experimental land, the aim of which was to know the best materials used in managing the corn stalk borer insect. Environmentally friendly materials were used (ash - remnants of burnt materials, in addition to table salt). In addition to our use of effective and approved pesticides in the control of stem borer in a field experiment to see the effect of the materials used on insect infestation rates It also had an effect on the killing rate of corn stalk borer larvae achieved by spraying with the experimental materials, in addition to its effect on the height of infected plants compared to the control treatmen Field surveys were conducted to find out the extent of infection with this insect in the center of Kirkuk Governorate. The experiment was repeated for the fall season 2022, with field surveys conducted for the purpose of confirming the economic importance of the insect.t. The results indicated the spread of the corn stalk borer insect in all corn-growing areas, for which tables were prepared regarding the infection rate. In the autumn season 2021 in Kirkuk Governorate. The results indicated that there was a clear effect of the materials used in the treatments, with a relative superiority of the ash and table salt treatments over the pesticide treatments (Diazinon 10% granular and Aktara EC 25).
Studies in the past decade confirm that the growth of both gram-positive and gramnegative foodborne bacteria, yeast and mold can be inhibited by garlic, onion, cinnamon, cloves, thyme, sage, and other spices. Consumption of mycotoxin contaminated foods has been associated with several cases of human poisoning, or mycotoxicosis, sometimes resulting in death. This study concluded that: When the ration or the fish suffered from fungal infection the addition of black seed, garlic and onion will reduce the infection and improve fish health. In Post mortem lesions the fish suffered from mycotic infection showed severe degenerative changes in internal organs especially in the liver, heart and kidneys. The result cleared that, the blackseed is the best herbs that prevented and improve the aflatoxin effect followed by garlic and onion, respectively. The result also showed that level of RBCs and WBCs, differential leucocytic counts, phagocytosis process, serum protein, biochemical analysis of fish body, body weight and body weight gain improved with addition of blackseed, garlic and onion. The residue of aflatoxin in fish flesh decreased in the groups treated with blackseed, garlic and onion than the control or fish fed on the aflatoxin. The results also showed that, frequent supplementation of fish ration with black seed, garlic and onion can reduce the aflatoxin hazards in the fish. The results also concluded that, the higher economic efficiency measures (total return, total costs, net profit, total returns/total costs and net return to total costs) improved in the groups fed with blackseed, garlic, onion and all of them improved economic efficiency measures than the control groups and when all of them added to the fish treated with aflatoxin diet improved economic efficiency results than the group treated with aflatoxin only.
The study was designed to analyze the seasonal dynamics of the nutritive value of endemic plant species (Berberis lycium, Indigofera heterentha, Parrotiopsis jacquemontiana, Rosa macrophylla and Rosa webbiana) and composite pasture grasses in different age groups of sheep using double indicator method. Twenty Kashmir Merino sheep from the two age groups in each season of summer (June) and autumn (October) were selected and divided into Group I (about 4 months of age) and Group II (1–2 years of age) in a 2 × 2 factorial design. The metabolizable energy (ME) of plants and composite grasses range from 10.11 to 12.60 and 7.32 to 9.94 MJ/kg, respectively, across different seasons. The quality of plants and the composite grass samples, measured in terms of total digestible nutrients, ME, crude protein and fiber content deteriorated with the advancement of the season. Palatability, nutrient and mineral intake, D and relative feed quality values were better during the summer than the autumn season. ME intake in younger sheep (Group I) was deficient by 32.5% compared to maintenance requirements during the autumn season. It was found that adult sheep tend to optimize their energy requirements from pastures while younger sheep fail to do so.Abbreviations: ADF: Acid Detergent Fiber; ADL: Acid Detergent Lignin; Ca: Calcium; CP: Crude Protein; D value: Digestible organic matter in dry matter; DCP: Digestible Crude Protein; DMI: Dry Matter Intake; EE: Ether Extract; ME: Metabolizable Energy; NDF: Neutral Detergent Fiber; OM: Organic Matter; P: Phosphorus; RFI: Relative Feed Index; TDN: Total Digestible Nutrients
