A 49-d feeding trial, using 192 growingfinishing pigs (avg initial wt, 32 kg), was conducted to identify pigs of widely differing average daily gains (ADG) when fed 16% crude protein diets containing either 0, 7.5 or 15% corn cobs. There were linear decreases in both ADG (P<.01) and gain/feed (P<.001) with increasing levels of dietary corn cobs. Average daily feed intake increased linearly (P<....

The gut microbiota plays an important role in nutrient digestibility in animals. To examine changes in the pig gut microbiota across growth stages and its effects on nutrient digestion, the gut microbiota population in pigs at 28 days (before weaning), and 60, 90, and 150 days of age was assessed by 16S rDNA gene sequencing. The apparent digestibility of crude fiber (CF), neutral detergent fibe...

The objectives of this study were to evaluate the effects of dry matter (DM) content and three different storage systems on the quality of alfalfa ensiled on commercial farms. Alfalfa silage samples were collected from 21 bunker silos, 20 silos that limited oxygen infiltration, and 19 tower silos on 43 commercial dairy farms. Storage system and DM content were confounded because silages from bu...

The objective of this study was to evaluate the use calcium oxide (CaO) on nutritive profile, digestibility, and carbohydrate fractionation three sugarcane (Saccharum officinarum hybrids) genotypes: IAC-862480, SP-791011, CTC-3. Four CaO levels (0, 1.5, 3.0, 4.5% a fresh matter basis) were used in 3 × 4 factorial scheme, whose factors genotypes four oxide. chemical composition, fractionation, t...

Information on forage quality could help rangeland managers to select suitable grazing method to achieve higher animal performance without damage to vegetation. The aim of this study was to determine and compare the forage quality of S. yazdiana and S. tomentosa, which are the most important species of saline rangelands in Ardakan in Yazd province, Iran. These two species are grazed by goats an...

We compared prediction of in vivo dry matter (DMD) and neutral detergent fiber (aNDFD) digestibility by the following techniques: (1) Tilley and Terry two-stage in vitro (conventional in vitro or IVDMD), (2) DaisyII in vitro (DaisyII), and (3) filter bag in situ preceded by 48 h acid–pepsin treatment. In addition, we also evaluated the effects due to sample size (0.25 g versus 0.50 g) and Wiley...

Livestock obtain forage by grazing on rangeland. In California annual rangelands, residual dry matter is commonly used to determine proper levels. Rangeland biomass and quality can degrade dramatically during the dormant summer period. We examined 25 sites across an rainfall gradient (183–492 mm) over 3 contrasting yr (2015–2017) that varied from 57% 152% of average precipitation. Overall fract...

The effects of different additives, including lactic acid bacteria inoculants, acremonium cellulase and mixtures of lactic acid bacteria inoculants and acremonium cellulase on changes of nutritive components and in vitro digestibility of Ceratoides arborescens during ensiling were investigated. The silages of each treatment were prepared in plastic film bags, kept in an incubator at 30°C and ba...

Teosinte (Euchlaena mexicana) is one of the most popular summer growing cereal fodder, yet with comparatively low level chemical constituents. The quality this fodder can be improved through better by cultivation management including sowing dates and mixed cropping legume. main objective study was to determine forage as reflected major constituents pure stands teosinte binary mixtures commonly ...

Objective: The objective of this study was to determine the nutritional content palm kernel meal (PM) produced in state Chiapas, Mexico, as feed for ruminants. Design/Methodology/Approach: following were determined: dry matter (DM), total protein (TP), ethereal extract (EE), ash, neutral detergent fiber (NDF), acid (ADF), amino acids, long chain fatty acids (LCFA), minerals, polyphenols, and vi...
