Background: Fat supplementation in ruminants ration often adversely affect dry matter intake (DMI), rumen fermentation and nutrients digestion. Basal diet ingredients is an undeniable determinant of ruminants responses including performance, chewing behaviour and nutrient digestibility to fat supplementation. Objective: Current study was conducted to evaluate the effect of Fish oil (FO) supplem...

Eliminating toxins from the hay begins in the field. However, toxic weeds frequently end up in hay and forage and pose a serious risk to livestock. The effects of poisonous plants on animals depend on the amount ingested and the individual weed present in hay. Many indications for poisoning exist. Obvious cases involve sudden onset of disease in a number of animals. Finding of common feed or en...

Alfalfa is the most productive and highest quality forage species. Over one million acres of alfalfa have been harvested each year in Montana since 1960. Yield and forage quality of alfalfa vary widely across environments and operations. Currently there is much interest in targeting specialized hay markets. Most Montana producers can consistently produce alfalfa that is of fair to good quality....

The objectives of this study were to measure particle size and evaluate the effect of increasing alfalfa hay particle size on production characteristics in lactating Holstein dairy cows. Ninety multiparous Holstein cows in early to mid-lactation were randomly assigned in a complete randomized design for a 30-day period. Animals were offered one of the three diets, which were identical in energy...

The present study was mainly conducted to determine whether dietary leucine supplementation could attenuate the decrease of the mucin production in the jejunal mucosa of weaned pigs infected by porcine rotavirus (PRV). A total of 24 crossbred barrows weaned at 21 d of age were assigned randomly to 1 of 2 diets supplemented with 1.00% L-leucine or 0.68% L-alanine (isonitrogenous control) for 17 ...

The in vivo digestibility, the rates of fermentation and passage and the rumen fermentation pattern were compared in ̃ Granadina goats and Segurena wethers fed alfalfa hay (AH), alfalfa hay/sugar beet pulp, 4:1 (AH/SB) and alfalfa hay/sugar beet pulp /oat grain, 3:1:1 (AH/SB/OG) at approximately maintenance level. The animals were at stall and no selectivity was practised. The nylon bag techniqu...

this experiment was conducted to evaluate the effect of camelthorn (alhagi sp.) as a foraghe in the diet of balouchi sheep (during the last two months of gestation and two months of lactation) where 72 ewes in a completely randomized design with three treatments (diets) and four replications were used. experimental diets were : 1) wheat straw 50%, alfalfa hay 30% and barley grain 20%, as contro...

Two trials were conducted to investigate the effects of disodium fumarate (DSF; 0.00, 8.00, 10.00 and 12.00 mM) and thyme essential oil (TEO; 0.00, 100.00, 200.00, 300.00 and 400.00 µL L-1) solely and simultaneously (10.00 mM DSF along with 100.00, 200.00, 300.00 and 400 µL L-1 TEO) on in vitro ruminal fermentation of a 50:50 alfalfa hay to concentrate diet. The D...

To evaluate the protein quality and postgut N utilization of full-bloom timothy hay, oat-supplemented timothy-hay diets, and alfalfa hay harvested at different maturities, apparent whole tract N digestibility, urinary N excretion, and serum AA profiles were determined in light to moderately exercised Arabian horses. Six Arabian geldings (16.0 ± 0.3 yr; 467 ± 11 kg of BW) were randomly allocated...
