Article Abstract
Background: Maize is an excellent fodder crop due to its high biomass, better palatability, succulency, and nutrition. Studies on morpho-physiological and biochemical characterization of fodder maize are limited. The present study aimed to explore the genetic variation in fodder maize landraces for various morpho-physiological traits and estimation of genetic relationship and population structure.
Methods And Results: The study on 47 fodder maize landraces revealed significant variation for all morpho-physiological traits except leaf-stem ratio. Plant height, stem girth, leaf-width and number of leaves showed positive correlation with green fodder yield. Morpho-physiological traits-based clustering grouped the landraces into three major clusters, whereas neighbour joining cluster and population structure analysis using 40 SSR markers revealed four and five major groups, respectively. Most landraces of Northern Himalaya-Kashmir and Ludhiana fall into a single group, whereas rest groups mainly had landraces from North-Eastern Himalaya. A total of 101 alleles were generated with mean polymorphic information content value of 0.36 and major allele frequency of 0.68. The pair wise genetic dissimilarity between genotypes ranged from 0.21 to 0.67. Mantel test revealed weak but significant correlation between morphological and molecular distance. Biochemical characterisation of superior landraces revealed significant variation for neutral detergent fibre, acid detergent fibre, cellulose and lignin content.
Conclusion: Interestingly, significant, and positive correlation of SPAD with lignin content can be explored to bypass the costly affair of invitro quality assessment for digestibility parameters. The study identified superior landraces and demonstrated the use of molecular markers in genetic diversity assessment and grouping of genotypes for fodder maize improvement.

This experiment evaluated the effects of replacing one-third of corn grain in a finishing diet with rye grain (RG) processed using one of three processing methods. Predominately Angus steers (n = 192, initial shrunk BW = 410 ± 20.9 kg) were blocked by source and pen location and assigned to one of four dietary treatments: dry-rolled corn (DRC), unprocessed RG (UNP), dry-rolled RG (DRR) and hammer-milled RG (HMR).

This experiment evaluated the effects of supplementing yeast culture ( ) on in situ ruminal degradability, rumen fermentation and microbiota responses of heifers consuming a forage-based diet. Twelve ruminally-cannulated Angus-influenced heifers were ranked by body weight ( 180 ± 4 kg) and assigned to 4 groups of 3 heifers each. Groups were enrolled in a replicated 3 × 3 Latin square design containing 3 periods of 21 d and 14-d washout intervals.

Two experiments were conducted to evaluate the effects of feeding dry-rolled hybrid rye grain (DRRG) as a replacement for dry-rolled corn (DRC) in beef cattle finishing diets. Two inclusion strategies for rye grain (RG) were evaluated: a total replacement of DRC for a limited time and a partial replacement during the entire feeding trial for Exp. 1 and 2, respectively.

The function of fermented and non fermented bamboo-derived feed additives in poultry nutrition is critically assessed in this review, with emphasis on the effects on growth performance, immunity, intestinal health, egg and meat quality. Fermented bamboo feeds have become a promising nutritional innovation in poultry production. The use of bamboo leaves and tender shoots in chicken feed is limited due to the presence of lignin and cellulose.

The objective of this study was to evaluate the effects of forage fiber and starch sources replacement with delactosed whey permeate (DLP) on lactation performance and total-tract nutrient digestibility of high-producing dairy cows. Ninety-six multiparous Holstein cows (88 ± 36 DIM) and dietary treatments were randomly assigned to 12 pens of 8 cows for an 8-wk treatment period, after a 2-wk covariate period. Treatments were diets fed without DLP (CON), 5% replacement of corn silage with DLP (LCS), and 5% replacement of high-moisture corn with DLP (LHMC).
