Antibiotics at sub-therapeutic levels are often used as feed additives to increase the efficiency of conversion into milk and meat and/or prevent disease metabolic problems. Under realistic feeding conditions, ionophoric antibiotics such monensin have proven be most efficient manipulators rumen microbiota fermentation. Despite these desirable effects on animal performance, use in diets has become a public health concern because their potential role emergence antibiotic-resistant bacteria. In...

Background and Objectives: Supplementing diets of dairy animals with phytase xylanase can enhance phosphorus availability fiber degradation in the rumen positively affect animalʼs health productivity.In vitro vivo trials have been conducted to define optimal addition level lactating Baldi goatʼs rations investigate effects these enzymes on nutrients digestibility, blood chemistry, milk production composition.Materials Methods: In batch culture technique was used evaluate effect...

Background: Synchronization the rate of which dry matter and crude protein degraded at rumen significantly affects synthesis microbial thus efficiency feed utilization.During previous study a new software application "Lacto-sheep" had been developed to facilitate formulation least cost ration considered this important factor.So that synchronous is possible not difficult.This was carried out investigate advantages feeding as an alternative traditional on nutrients digestibility milk...

Microfiber fabrics are more efficiency in retaining fine-particles that increase the variation situ degradability. The aim of this was to examine performance bags made from different microfiber fabric for meeting required specification and their ruminal degradability compared with standard Ankom bags. Four were manufactured using polyester 1.04 denier, weft yarn counts (150 300), density (22 28 picks / inch), plain 1/1 textile structure. Physical mechanical properties measured before after...

Moringa seed cake is a protein-rich source that can be utilized as feed supplement or cheaper protein ingredient.This study aimed to: (1) assess the ruminal degradation features of machine-dehulled moringa (DMSC); and (2) examine effect supplementing lactating Damascus goats' diets with DMSC on milk production.Three cannulated rams (50.60± 3.05 kg, body weight) were used to degradability DM, NDF, ADF for using in sacco technique.Fifteen goats (averaging 45.4± 0.5 weight averaging yield...

oringa seed oil (MSO) was used as a feed additive to evaluate its potential manipulate rumen fermentation and productive performance in lactating Ossimi ewes.Cold extracted MSO supplemented at four different levels (1, 2, 3, 4%) diet using vitro batch culture system for optimizing best supplementation level sheep.Results of study revealed non-significant (P>0.05)effect on true dry matter degradability (TDMD) up 3% inclusion level, however, decrease TDMD observed by 4% compared control other...

This study assessed the impact of oral administration zinc oxide (ZnO) and selenium (Se) nanoparticles on milk production gene expression in Baladi goats. Twenty-two pregnant females, 30 days before parturition, were divided into five groups: Group 1 (n=4) served as control; Groups 2 3 (n=4 each) received 150 mg ZnO 0.3 Se microparticle (MP) forms, respectively; 4 5 (n=5 15 0.03 nanoparticle (NP) respectively. Milk yield, composition, related to analyzed. Results indicated a significant...

Cellulase as a fibrolytic enzyme is highly effective tool for agricultural waste treatments. Production of cellulase on medium wastes by Fusarium graminearum to be used in ruminant feeding was the main objective this study.Impact initial pH growth medium, different nitrogen sources and variety agriculture products carbon production have been studied. Electron microscope investigate impact resultant corn stover degradation, while batch culture technique levels produced commercial cellulases...

In situ bags made from microfiber fabrics have a greater surface area and filtration efficiency that retains the fine particles reduce variation in results. Also, it is more durable than traditional fabrics. This work aimed to study effect of filament denier on performance bags. Two polyester microfilaments with 0.4 0.7 deniers were used manufacturing four Physical mechanical properties manufactured measured before after incubation show samples. vitro trail was conducted estimate ruminal...

ates that have been discarded are rich and inexpensive source of energy represent a promising replacement for costly concentrates in livestock feeding.This research evaluated the impact increasing levels dates as substitute yellow corn grain on intake, nutrient digestibility, performance lactating Barki ewes.Twenty multiparous ewes (38.2 kg ± 1.18) were randomly divided into four groups (five per group).The feeding trial lasted 60 days, followed by digestion trials.Ewes fed diet concentrate...

his study evaluated the effects of partially substituting Berseem clover (BC) with Moringa Oleifera leaves on lactating Barki ewes' performance.Three cannulated rams (51.50±4.0kg, body weight) were used to evaluate ruminal degradation DM, NDF, and ADF for (ML) using in situ nylon bag method.The true dry matter digestibility, total gas production (ml/400 mg DM), fiber fractions degradability investigated vitro batch culture.A lactation trial was conducted fourteen multiparous ewes (averaging...

Moringa oleifer tree products are riches in various bioactive ingredients that have a good role dairy products. This work aimed to study the effect of adding different (oil, leave, and cake) ewe’s rations on milk composition as well chemical, sensory microbiological properties resultant yoghurt. Thirty-five lactating Barki ewes were randomly assigned into five groups. Each group was feed diet containing ratios type The first control (C) other four groups classed follow: Group (1): 2.5% seed...
