Assessment of the nutritive value of corn stover and king grass in complete feed on Ongole steer calves productivity

Abstract

<jats:p>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 4 weeks. In every interval, weight gain and digestibility were measured every day, beginning from the 4th week 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&lt;0.05) the feed nutritional value and weight gain of male Ongole steer calves. Interestingly, treatment with R4 had the maximum increase (p&lt;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.</jats:p>

Effects of Replacement of Wheat Straw with Corn Stover Based TMR on Growth Performance, Behavioural Characteristics, selected Blood Metabolites and Nutrient Digestibility in Beetal Bucks.

“…Kanyinji et al (2017) reported negative effects of inclusion of CS in the ration of goats. In agreement with the current ndings, Tuturoong et al (2020) reported an increased DM, OM, CP and NDF digestibility in the small ruminants fed CS based ration. The decreased nutrient digestibility by dietary inclusion of WS as crop residue may possibly be due to higher lignin contents than corn stover.…”

“…670. It could result that the feeding has not, in general, met the recommended feed needs, either quality or quantity, to push the weight growth so the addition of feed costs is needed to shorten the rearing time and increase the body weight [21]. The feed quality improvement will be beneficial for reducing the fattening time and yielding higher daily weight growth [22] so that the farmer's income increases.…”

“…One reason for livestock productivity being low is the scarcity of high-quality feed. Not only is feed limited by its nutritional value, but also by its sustainability [2], [3]. During the dry season, it will be more challenging to obtain feed because it will typically be abundant during the rainy season.…”
