BUFFALO CALVES. Calves eventually serve as the productive unit of the herd and need to be protected, managed, and fed properly for their population to grow economically at an optimum rate. Underfeeding significantly reduces growth rates to 50% during the rearing phase which may cause delayed puberty. Castillo et al. (2023) studied the effects of hydroponic corn fodder on the growth performance of buffalo calves. Supplementing buffalo calves’ diets with hydroponic corn fodder could have a beneficial effect on their growth performance and economic viability. Overall, hydroponic corn production has a great potential as a sustainable source of fodder for ruminants to support the nutritional requirements. {Photograph courtesy of Mikee A.

This study investigated the nutritional and functional components of ‘saba’ banana peel (SBP) to determine its health-promoting potential for special food applications. SBP has undergone analyses measuring proximate composition, vitamin C, antioxidant activity, phytochemical content, estimated glycemic index (eGI), pancreatic lipase inhibition, and cholesterol micellar solubility inhibition. Data were processed using SPSS v20 and expressed as mean ± SD. Proximate analysis showed that SBP contained 83.83 ± 1.06% moisture, 6.74 ± 0.83% crude fat, 5.58 ± 0.24% crude protein, 9.97 ± 0.04% total ash, 9.91 ± 0.10% crude fiber, and 60.08% nitrogen-free extracts. Vitamin C content was found to be...

This study investigated the effects of hydroponic corn fodder on the growth performance of buffalo calves. Twelve Bulgarian Murrah buffalo calves were divided into two treatment groups: T1, fed with Napier grass and starter feed concentrates, and T2, fed with Napier grass, starter feed concentrates, and hydroponic corn fodder, replacing 50% of the starter feed concentrate. The study found no significant differences between the two groups' average total weight gain and average daily gain. However, the average daily feed intake was significantly higher in T2, possibly due to the tender and young nature of the hydroponic corn fodder. Dry matter and crude protein intake did not show any signi...

A region’s agricultural sector plays a strategic role in fulfilling its food needs with ideal nutrition. The potential of cereal commodities, specifically rice and corn, was identified based on the production level and competitiveness by district in Buleleng Regency, Indonesia. The regency’s potential to provide and support food security was also determined through a quantitative descriptive analysis of the Location Quotient (LQ), Shift Share Analysis (SSA), Localization Coefficients, and Levels of Food Availability by utilizing secondary data on cereal commodity production and population numbers over the course of 10 yr (2012–2021). Results showed that Sawan, Seririt, and Sukasada distri...

Received: August 15, 2020/ Revised: May 08, 2023/ Accepted: July 10, 2023 https://doi.org/10.62550/HQ065020

Surface runoff and soil erosion of the Upper Lagawe River Sub-watershed, Ifugao Province, Philippines were quantified using Geographic Information Systems (GIS)-based numerical simulation. PCRaster software was used as a framework for the model. Manning’s and Rose, and Freebairn’s Equations were utilized to compute surface runoff velocity and sediment mass. Analysis and comparison of the measured and predicted streamflow yielded a mean Nash and Sutcliffe Efficiency Index of 0.70, a mean percent bias of - 8.38%, and a mean root mean square error (RMSE) of 0.16. Based on the model, super typhoon Lando (international name: Koppu) generated an estimated surface runoff volume of 186000 m3 and ...

The Effect of AMF-Cacao Association on Varying Physicochemical, Nutrient, and Biological Soil Parameters in an Agroforest System

Received: October 18, 2021/ Revised: April 17, 2023/ Accepted: August 04, 2023 https://doi.org/10.62550/JN125021

The increasing interest in sustainable methods in agroforestry directs the attention of many to arbuscular mycorrhizal fungi (AMF) for their role in maintaining or improving overall plant health and nutrition of many plants including cacao (Theobroma cacao L.) trees. The effects of different treatments of AMF and other soil amendments applied singly or in combination on physicochemical properties, nutrient levels, spore count, and rhizosphere microbial counts, were investigated and compared across different sampling periods of varying climatological conditions in an agroforest system. Results showed that there was a significant effect on the N content using the different treatments. The t...
