This study aims to quantify the phosphorus (P) concentration in the commercially adapted ten corn hybrids in South Dakota and to determine if selection can be carried out for these traits to develop useful inbred lines; to determine the effect of planting densities on P concentrations and dry matter (DM) yields. Results showed that hybrid were significantly differences for percent phosphorus. H...

This study examined the influence of re-growth periods on chemical composition, biomass production, nutritive value and digestion kinetics of Setaria sphacelata (SS) and Cenchrus ciliaris (CC) in ruminally cannulated buffalo bulls. Two re-growth intervals i.e. clipping every month (CI1) and clipping after every two months (CI2) were compared with the control (clipped after 4 months). Mean value...

The objective of this study was to assess the effect of substituting corn with soybean hulls on the ingestive behavior and nitrogen balance of Santa Ines lambs. A total of 25 lambs with an initial body weight of 20±2 kg at approximately six months of age, sheltered individually in stalls (1.10 m×1.0 m), considering an entirely casual experimental delineation. Soybean hulls were substituted for ...

Changes were found in the cell wall composition of lucerne after ensiling at three different dry matter (DM) contents. The amount of protein associated with cell walls was reduced during ensiling, regardless of inoculation level, by 4 M 8 %, whereas protein associated with the lignin residue was reduced to a lesser extent (< 40%). The effect of ensiling on individual sugars of the cell wall var...

Sixteen Holstein cows in midlactation were used in a 4 × 4 Latin square design to determine the effect of replacing alfalfa neutral detergent fiber (NDF), with NDF from a combination of whole linted cottonseed, dried distillers grains, and wheat middlings. The four diets were a basal control diet that was low in forage and fiber [(5.9 g of corn silage NDF and 6.1 g of alfalfa NDF/100 g of dry m...

To evaluate the effects of garlic on some blood metabolites in pre-partum dairy goats, the ration was supplemented with raw garlic at the doses of 0, 30, 50 and 70 g kg(-1) of Dry matter (DM) in eight pregnant Mahabadi breed goats (59 ± 1 kg initial live weight) in a replicated Latin square design during the last two months of pregnancy. Each experimental period lasted 14 days with the first 12...

To examine the effect of including oil in diets on early lactating productive performance parameters including; dry matter intake, milk production and components, body condition score, body weight and negative energy balance; twenty multiparous Holstein cows were randomly assigned to the experimental diets from 21 days before predicted calving time to 50 days in milk. Treatments including 1) co...

We conducted two experiments to evaluate the effects of corn supplementation, source of corn, and corn particle size on performance and nutrient utilization of lactating dairy cows. In experiment 1, treatments were 1) direct-cut grass-legume forage without supplement, 2) direct-cut forage plus 10 kg DM of ground dry shelled corn-based concentrate, and 3) direct-cut forage plus 10 kg DM of coars...

Purpose of the experiment was to evaluate effect lemon-seed essential oils on chemical composition and in vitro degradability alfalfa silage. Treatments were silage with no additive (control) or treated 60 ml/kg DM (C60), (C120) equal mixed them (M60). Whole plant ensiled for d triplicate laboratory scale tubes. Dry matter, organic crude protein, insoluble fiber acidic neutral detergent, water ...
