Abstract

Aim:This study aimed to assess the nutritional values of corn stover and king grass (Pennisetum purpupoides) in complete feed on the productivity of male Ongole steer calves.Materials and Methods:This study was conducted in two steps: Cattle adaptation and data collection. Cattle adaptation was carried out for 2 weeks, and the cattle were fed the experimental feed. The experimental feed was formulated into five combinations: R1 (50% king grass); R2(12.5% corn stover +7.5% king grass 50% concentrate); R3(25% corn stover+25% king grass); R4(37.5% corn stover+12.5% king grass); and R5(50% corn stover). All experimental feeds were added with 50% concentrate. Data were collected in five intervals, and each interval was of 4weeks. In every interval, weight gain and digestibility were measured every day, beginning from the 4thweek by collecting feces. Dry matter (DM), organic matter (OM), crude protein (CP) digestibility, neutral detergent fiber (NDF), acid detergent fiber (ADF), body weight gain, and feed conversion data were analyzed.Results:R4 and R5 treatment significantly increased (p<0.05) the feed nutritional value and weight gain of male Ongole steer calves. Interestingly, treatment with R4 had the maximum increase (p<0.05) on the digestibility value of each variable: DM, 68.85%; OM, 71.89%; CP, 73.90%; NDF, 59.10%; ADF, 55.35%; and weight gain, 0.61/gr/day.Conclusion:R4 treatment found to be the best nutritional value for improving the productivity of male Ongole steer calves.

Highlights

Corn stover consists of stalk, leaves, cob, and flower of corn left in the field after harvesting on the 45th-46th day after their plantation [1]
The evaluation of the digestibility value of Dry matter (DM), organic matter (OM), crude fiber (CF), cellulose, and hemicellulose of corn stover and king grass in complete feed on organochlorine (OC) cattle is presented in Table-3
The results showed that the DM digestibility (DMD) of feed comprising of corn stover and king grass in this study ranges from 65.95% to 68.85%

Summary

Introduction

Corn stover consists of stalk, leaves, cob, and flower of corn left in the field after harvesting on the 45th-46th day after their plantation [1]. Corn stover contains slightly more crude protein (CP) (12.06%), crude fiber (CF) (25.02%), and a net energy content of 2350 Kcal/kg [2]. Corn stover contains 91.94% dry matter (DM), 43.23% organic matter (OM), 94% lignin, 4.95% silica, 68.78% neutral detergent fiber (NDF), and 42.36% acid detergent fiber (ADF). The digestibility of DM and OM of corn stover, which ranges from 59.48% to 88.71%, is considerably higher when compared with other fodders [3]. Supplementation with by-products of local crops such as rice bran and legume leaves increases feed intake and digestibility. Corn stover without supplementation has been reported to increases cattle weight by 0.55 kg/cow/day, whereas supplementation with rice bran and legume leave increases it by 0.77 kg/cow/day [4,5]
