Twenty-four lactating Holstein cows were used in an 8-wk completely randomized design trial to examine the effects of feeding whole cottonseed (WCS) with elevated concentrations of free fatty acids (FFA) in the oil on intake and performance. Treatments included WCS with normal concentrations of FFA (6.8%, control) and 2 sources of WCS with elevated FFA [HFFA1 (24.1%) or HFFA2 (22.3%)]. The 2 so...

Milk samples averaging 500 ml were collected weekly from 10 to 54 days postpartum from five lactating mares. Samples were obtained by hand milking after oxytocin administration and while the foal nursed. Dry matter, protein and gross energy were higher in samples obtained at 10 and 17 days postpartum than those obtained during the midlactation period of 24-54 days. Midlactation samples averaged...

21 Three levels of metabolizable protein supply (108, 98–95 and 85 g PDIE kg DM) (PDIE: protein digested in the small intestine when rumen-fermentable energy is limiting) in the diet and three levels of difference between rumen-degradable 21 energy and N (PDIE 2 PDIN 5 0, 10 and 20 g kg DM) (PDIN: protein digested in the small intestine when rumenfermentable nitrogen is limiting) were used in t...

The present study was carried out to evaluate the effect of prill fat and rumen protected choline supplementation on daily dry matter intake, body weight changes and economics in lactating Murrah buffaloes (n=18) divided into three equal groups (Control, T1 and T2). Buffaloes in all the three groups were fed similar basal diet as total mixed ration comprising of berseem green fodder, wheat stra...

Ten Holstein steers (141 kg) were used in two 5 X 5 Latin-square experiments conducted simultaneously to determine the effects of offering different levels and types of feeds with endo: phyte-infected rescue given ad libitum. In Exp. 1, steers wer e given ad libitum access to infected fescue hay in the afternoon; in the morning fescue was given ad lihitum (basal) or bermudagrass or clover hays ...

Wheat straw was fermented by Crinipellis sp. RCK-1, a lignin degrading fungus, under solid state fermentation conditions. The fungus degraded 18.38% lignin at the expense of 10.37% cellulose within 9 days. However, when wheat straw fermented for different duration was evaluated in vitro, the 5 day fungal fermented wheat straw called here "Biotech Feed" was found to possess 36.74% organic matter...

The goal of this study was to evaluate the effects of dosing unadapted lambs with tannin-tolerant bacteria to improve the digestibility of a high condensed tannin (CT) diet. During the initial phase (metabolism study), a diet containing 30% peanut skins was fed to two groups of Suffolk FinnDorset ram lambs that were about three months old and weighed an average of 24.2 1.4 kg. All animals recei...

Little is known about the effects of the high dose and types of manganese supplements on rumen environment at manganese intake level close above the limit of 150 mg/kg of dry feed matter. The effects of high dose of two manganese supplements (organic and inorganic) on rumen microbial ecosystem after four months of treatment of 18 lambs divided into three treatment groups were studied. We examin...

This study was conducted with the objective of evaluating the effect of concentrate supplementation, formulated with different ingredients (Mesquite pod meal, sorghum meal or wheat meal and mineral supplementation) on performance, intake and digestibility of nutrients in Santa Inês lambs grazing on urochloa grass during the dry season. Twentyfour uncastrated weaned Santa Inês sheep, with averag...
