The experiment was conducted to evaluate losses and nutritive value of elephant grass silage containing increasing levels of cottonseed meal. The experimental design was completely randomized, with five treatments: 0, 7, 14, 21 and 28% inclusion of cottonseed meal, and four replications. The material was chopped and packed in PVC silos and stored for 80 days. The pH and dry matter (DM), crude p...

Ten lactating multiparous Holstein cows were used in a cross-over design with two dietary treatments and 28-d periods (with 14 d as an adaptation) to study the effect of restaurant fat on milk production and composition. Each cow was offered 14.7 kg DM /d of the basal concentrate diet based on barley and corn (crude protein = 17.7%, neutral detergent fiber = 23.5%, and acid detergent fiber = 5....

A comparison between heavily browsed and non-browsed Juniperus pinchotii trees revealed that, in contrast to the recent J. ashei study (Adams et al., 2013), the percentage of total volatile leaf oil yields were not significantly different (P > 0.05) between non-browsed trees (1.08%, DM-basis) and browsed trees (0.94%, DM basis). Only one terpene in the mg/g data, α-pinene, was significantly dif...

Hedychium gardnerianum (HG) and Pittospporum undulatum (PU) are invasive plants all over the world, being in the Azores supplied to cattle on periods of shortage food. As these plants produce secondary metabolites, including a diverse range of phytochemicals compounds, the aim of the present study is to identify how these metabolites can be related to animal’s reproductive performances. For suc...

This study investigated the chemical composition and ruminal degradability of corn stover in three maize-planting regions in Qiqihaer, Heilongjiang Province, China. The whole stover was separated into seven morphological fractions, i.e., leaf blade, leaf sheath, stem rind, stem pith, stem node, ear husk, and corn tassel. The assessment of nutritive value of corn stover and its fractions was per...

The objective of this study was to compare utilization of red clover (Trifolium pratense L.) and alfalfa (Medicago sativa L.) by lactating dairy cows. Red clover and alfalfa were harvested and conserved as silage at two maturities in 2 consecutive yr. Each year, diets containing experimental forages and supplemental grain were fed to 16 multiparous Holstein cows in early lactation in a replicat...

The study aimed to investigate the effects of different levels added sucrose on fermentation quality and microbial community kudzu (Pueraria lobata) silage. three supplementation utilized were 0, 0.5, 1.0%, was silaged for 15, 30, 60 days. Sucrose significantly decreased pH levels, acid detergent fiber, ammonia nitrogen content, relative abundance Pantoea in silages (p < 0.05). addition 1% s...

Elephant grass is a tropical forage plant widely distributed throughout Brazil. It was first exclusively used in the livestock sector as cattle feed. The grass is characterized by its high productivity and photosynthetic capacity and is considered as an alternative source of renewable energy. Here, we estimated the general combining ability of the parents and specific combining ability of the h...

Objective: This study carried out to monitor the status of nutritional management and measuring difference between present and desired feeding system in dairy cattle of rural conditions of Chaharmahal and Bakhtiari. Methods: 334 rural flocks consisting of 1442 dairy cows were selected from seven towns of this province. The experiment was lasted for in a year and using completely randomized desi...
