The Effect of Iranian and Foreign Milk Substitutes on Performance, Blood Parameters, Characteristics Internal Carcass Organs Rumen Development Lambs at Weaning

The objective of this study was to assess the effects of milk replacer and rumen inert fat on growth, testicular development, puberty, semen production and sperm motion characteristics of ram lambs reared under intensive management in semi-arid climatic conditions. Seven-day-old male lambs of Malpura breed (n=20) were divided equally into two groups. Up to weaning, the lambs in G1 group (contro...

This study was conducted to investigate the effect of decreasing concentrations dietary neutral detergent fiber (NDF) at high rumen undegradable protein (RUP) on performance, digestibility, chewing activity, blood attributes, and carcass characteristics in 32 weaned male Afshari lambs (90 days age; 26 kg initial body weight; BW). Dietary metabolic energy (ME) increased from 10.6–11.5 11.8 MJ/kg...

OBJECTIVE The study examined the effect of condensed tannins (CT) containing Ficus infectoria and Psidium guajava leaf meal mixture (LMM) supplementation on nutrient metabolism, methane emission and performance of lambs. METHODS Twenty four lambs of ~6 months age (average body weight 10.1±0.60 kg) were randomly divided into 4 dietary treatments (CT-0, CT-1, CT-1.5, and CT-2 containing 0, 1.0,...

Background: In recent years, dietary fat supplementation has become a common practice and fat supplemented diets have had variable effects on animal performance and carcass characteristics. OBJECTIVES: This study was conducted to determine the effect of  increasing the levels of sesame oil on performance, rumen parameters and plasma lipid profile in finishing Chal lambs. METHODS: Eighteen male ...

this experiment was carried out to compare the effects of treated and untreated wheat straw with pleurotus florida on ewe feed intake, nutrient digestibility, and ewe body condition score (bcs) after parturition. thirty kermani ewes with an average weight of 48 ± 3.05 kg and about four years old were used in this experiment. synchronization of estrus in sheep has been achieved with the use of i...

introduction it has been estimated that pbp production based on fresh weight in iran is over 400,000 mt annually. pistachio by-products consist of 53.50% external hull (epicarp) with the remaining composed of leaves, mesocarp and kernel. the results of few studies showed feeding of low levels of pbp had no effects on sheep, dairy cow and goat performance. ensiled of pbp with peg, naoh and urea ...

I . Lambs fitted with cannulas in the abomasum, terminal ileum and caecum were used to study the digestion of starch and dry matter when rations with high starch content were given. Polyethylene glycol was used as an indigestible reference substance. 2. In Expt I reduction in level of feeding from an estimated ad lib. intake to 70% of this level reduced the amount of dietary starch escaping fer...

The study was composed of two parts. A one-factor design was adopted to investigate DMD, CPM, NDFD and ADFD of diet by total feces collection method in trial one. Twelve lambs were allotted randomly to 4 groups of 3 animals (replicates), which were fed with basal diet, basic diet plus 40 mg/kg urease inhibitor, urea diet, urea diet plus 40 mg/kg urease inhibitor. Experimental period consisted o...
