Twenty eight Ossimi male lambs, with an average live body weight 4.75 kg and 7 days age were randomly assigned to two feeding groups each of 14 animals to study the effect of pre-weaning diet on lamb's rumen development. Both the two groups suckled their dams until being weaned at 12 weeks of age (natural weaning). The first group depended completely on dam's milk as a solely available feed (co...

The objective of this study was to investigate the effects of diets containing different levels of milk thistle (0, 100 and 200 g/kg dry matter) and grains (barley and corn) with different rumen degradation rates on rumen bacteria and whole rumen microorganisms (WRM) of Khuzestan buffalo. The gas production (GP) technique, two steps digestion and specific bacteria culture medium methods were us...

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...

A survey of the components of the rumen ciliate population in a series of adult sheep, raised in the Faculty of Agriculture, University of Alexandria, has shown that a mixture of Entodinium, Isotricha, Ophryoscolex, Diplodinium, and Polyplastron species was found in the rumen contents of Egyptian sheep; no Epidinium and a negligible number of Dasytricha ruminantium were also observed. The micro...

The effects of initial live weight (LW; 18 and 30 kg), maturity (40 and 65% mature LW) and genotype on dry matter intake (DMI), LW gain (LWG), organic matter digestibility (OMD), rumen outflow rate of solid phase and urinary allantoin-N excretion were examined in 14 and 21 female lambs from the local breed Churra da Terra Quente (CH) and Ile-de-France (IF), respectively. LW at 40 and 65% maturi...

Two lamb trials were conducted to determine the effects of particle length (PL; 2.5 vs 10 cm) and sodium hydroxide (NaOH) treatment (0 vs 4%) of wheat straw on dry matter (DM) intake and site and extent of DM and neutral detergent fiber (NDF) digestion. Lambs in the first trial were fed ad libitum once daily. Lambs in the second trail were fed four t imes/d at 6-h intervals and were sacrificed ...

BACKGROUND The nature and amount of dietary medicinal plants are known to influence rumen fermentation and nutrient digestibility in ruminants. Nonetheless, changes in nutrient digestibility and rumen metabolism in response to dietary Andrographis paniculata (AP) in goats are unknown. This study examined the effects of dietary supplementation of leaves and whole plant of AP on nutrient digestib...

We used 28 crossbred wether lambs to determine the effects of dietary forage:concentrate ratio and metabolizable energy intake on visceral organ growth and oxidative capacity of gut tissues in lambs. Lambs were assigned randomly to a factorial arrangement of dietary treatments consisting of pelleted diets containing either 75% orchardgrass or 75% concentrate fed once daily at either .099 or .18...

This study aimed to analyze the economic feasibility of replacing soybean meal by sunflower cake in the diet of lambs. Twenty-eight non-castrated crossbred Suffolk lambs aged four months, with 21 kg average body weight ± 9 kg were used. These animals were distributed by weight category into 3 treatments (10, 20 and 30% dry matter (DM) addition of sunflower cake in replacing soybean meal) and co...

Negative interactions of the acidity and S content of dried distillers grains with solubles (DDGS) have not been quantified. The objectives of this study were to determine the effects of dietary S, dietary acidity, and their interactions on growth, feed efficiency, ruminal H2S concentration, and apparent nutrient digestibility in lambs fed DDGS-based diets. To neutralize acidity, the DDGS was u...
