Abstract The energy requirements, feed intake, and performance of grazing animals vary daily due to changes in weather conditions, forage nutritive values, and plant and animal maturity throughout the grazing season. Hence, realistic simulations of daily animal performance can be made only by the models that can address these changes. Given the dearth of simple, user-friendly models of this kind, especially for pastures, we developed a daily gain model for large-frame stockers grazing bermudagrass [Cynodon dactylon (L.) Pers.], a widely-used warm-season perennial grass in the southern United States. For model development, we first assembled some of the classic works in forage-beef modeling in the last 50 years into the National Research Council (NRC, 1984) weight gain model. Then, we tested it using the average daily gain (ADG) data obtained from several locations in the southern United States. The evaluation results showed that the performance of the NRC model was poor as it consistently underpredicted ADG throughout the grazing season. To improve the predictive accuracy of the NRC model to make it perform under bermudagrass grazing conditions, we made an adjustment on the model by adding the daily departures of the modeled values from the data trendline. Subsequently, we tested the revised model against an independent set of ADG data obtained from eight research locations in the region involving about 4,800 animals, using 30 years (1991-2020) of daily weather data. The values of the various measures of fit used, namely the Willmott index of 0.92, the modeling efficiency of 0.75, the R 2 of 0.76, the root mean square error of 0.13 kg d -1, and the prediction error relative to the mean observed data of 24% demonstrated that the revised model mimicked the pattern of observed ADG data satisfactorily. Unlike the original model, the revised model predicted more closely the ADG value throughout the grazing season. The revised model may be useful to accurately reflect the impacts of daily weather conditions, forage nutritive values, seasonality, and plant and animal maturity on animal performance.

Abstract Cacao pod husk has been widely utilized as animal feed. The purpose of this study is to evaluate nutritive values and digestibility of fermented cacao pod husk with different concentration and incubation time. A completely randomized factorial design consisting two factors; lingzhi mushroom concentration (K1 = 7,5%; K2 = 15%) and incubation time (L1 = 15 d; L2 =30 d; L3 = 45 d) was employed in this study (n=3 replicates). Proximate analysis was performed to determine nutritive values of fermented cacao pod husk. Fermented samples were then subjected to an in vitro digestibility with rumen fluid and McDougall’s buffer mixture. The results of study reveal that cacao pod husk fermented with the concentration of 15% at 15d and 30 d significantly increased (P<0.05) crude protein content but not for other parameters. Dry and organic matter digestibility of cacao pod husk fermented with 7.5% of lingzhi mushroom at 45 d significantly improved (P<0.05) in vitro dry and organic matter of treatment. In conclusion, cacao pod husk fermented with different concentration and incubation time was able to improve the nutritive values and in vitro digestibility of cacao pod husk.

This study was conducted to determine the mean concentration of heavy metals such as lead (Pb), copper (Cu), zinc (Zn), chromium (Cr), manganese (Mn), nickel (Ni), selenium (Se), magnesium (Mg), and iron (Fe) in canned/packed fruits juices, collected from various stores in Lahore in a period of three months. These juices were categorized into four groups; local packed and canned and also imported packed and canned products. Every group consisted of ten samples. By using the di-acid digestion method, the collected samples were digested and analyzed under Atomic Absorption Spectrophotometer (AAS). The results indicated that the mean values of 7 out of 9 tested heavy metals including Pb, Mg, Ni, Fe, Cr, Se and Mn were above permissible limits (set by WHO) in all four understudy groups. Therefore, it was concluded that commercially available fruit juices are not all safe according to their heavy metals content for the human consumption despite their nutritive values.

Raw ingredients commonly used in the cat food manufacturing are derived fromvarious sources such as meat, meat by products, fish, poultry, vegetables, vegetables byproducts, cereals, fruits, and bones. Meat meal and meat bone meal are unpopular rawingredients since they are manufactured from carcasses and offal of cows, pigs, goats andsheep and may even contain deleterious and unhealthy ingredients. There is the possibility ofthe occurrence of ingredients containing non halal components. There are several types of catfood in the market which are graded based on their ingredients and nutritive values especiallythe protein content. The biological values of the popular protein sources used in cat foodmanufacturing were highlighted. The importance of carbohydrate content, which is mostlynot available on the packaging pack is emphasized and the method of calculation shown.

Background. A detailed study on the feed quantity and quality is required to document the available feeds and their nutritional values. Aim. The study was aimed to investigate and document the chemical composition and in vitro dry matter digestibility of major feed resources available in Tanqua-Abergelle district of central Tigray, northern Ethiopia. Methods. Ten different feed resources were evaluated for their nutritive values. Representative feed samples were collected and prepared following appropriate procedures. The samples were subjected to analysis of chemical composition and in vitro dry matter digestibility (IVDMD) using proper scientific procedures. Results. Wide variations were observed in nutritive values of the investigated feeds. The highest crude protein (CP) was measured in Atella (15.90%) followed by green grass (13.20%), mill waste (10.90%), groundnut straw (9.18%), and cowpea straw (8.11%) in descending order. Mill waste (11.84 MJ/kg DM) and Atella (11.81 MJ/kg DM) had the highest metabolizable energy (ME) followed by green grass (9.83 MJ/kg DM), groundnut straw (9.28 MJ/kg DM), Teff straw (8.56 MJ/kg DM), and cowpea straw (8.39 MJ/kg DM) in that order. The highest NDF was recorded in groundnut null (79.80%) and the lowest NDF in mill waste (35.00%) and Atella (40.60%). The highest IVDMD was seen in mill waste (81.43%) and Atella (81.21%) and the lowest in groundnut hull (39.95%). Conclusion. The nonconventional feeds have moderate protein and reduced fiber contents, and thus, they can be utilized as supplement for poor-quality feeds. These feeds need further investigation using animals to substantiate the current study.

Date palm fruit (Phoenix dactylifera L.) is commonly consumed around the world and has recently become an economical crop in Eastern Thailand, especially the Barhi cultivar that can be consumed as fresh fruit. To maintain genetic qualities, date palm is populated through cell culture. This leads to high production costs, while access to this technique is limited. Increasing date palm population by simple seed planting is currently of interest as an alternative for local farmers. Nevertheless, information on nutritive values, bioactive compounds, and health-promoting bioactivities of seed originating from date palm fruit is unavailable. Effects of different planting origins (cell culture origin (CO) and seed origin (SO)) of date palm fruits at the Khalal stage of Barhi cultivar were investigated for nutritive values, bioactive compounds, and in vitro health-promoting properties via key enzyme inhibitions against obesity (lipase), diabetes (α-amylase, α-glucosidase, and dipeptidyl peptidase-IV), Alzheimer’s disease (cholinesterases and β-secretase), and hypertension (angiotensin-converting enzyme). Waste seeds as a by-product from date palm production were also examined regarding these properties to increase seed marketing opportunities for future food applications and other health-related products. CO and SO exhibited insignificant differences in energy, fat, and carbohydrate contents. SO had higher protein, dietary fiber, vitamin A, vitamin E, and calcium contents than CO, while CO contained higher contents of fructose, glucose and maltose. Higher phenolic contents in SO led to greater enzyme inhibitory activities than CO. Interestingly, seeds of date palm fruits mostly contained higher nutritive values than the flesh. No carotenoids were detected in seeds but higher phenolic contents resulted in greater enzyme inhibitory activities than recorded for fruit flesh. Results suggest that appropriate planting of date palm can support the development of novel date palm fruit products, leading to expansion of economic opportunities and investment in date palm fruit agriculture.
