Hominy feed (HF) has been evaluated in feedlot and dairy rations but not as a supplemental energy source for lactating beef cows. The objective of this study was to determine the effect level HF supplementation on intake, digestibility, ruminal fermentation characteristics, situ dry matter (DM) disappearance bermudagrass hay. Five ruminally cannulated cows (body weight (BW) = 596 kg, SE 13.9) w...

The objective of this study was to evaluate the effects of weaning age on dry matter intake (DMI), average daily gain (ADG), feed efficiency (FE), feed cost (FC) and benefit index (BI) of Holstein calves reared under organic farming system. Thirty two Holstein calves were divided into two treatments: early weaning (EW) vs. late weaning (LW). Calves in the both groups were provided with whole mi...

Thirty two multiparous Holstein cows were used in a randomized block design to investigate the effects of feeding diets included two different source of nonfiber carbohydrate during the transition period on dry matter intake (DMI), lactational performance, blood metabolites and parturitional characteristics. Cows received total mixed rations containing either macaroni wastes(MW) or steam-flaked...

Defined mixtures of two grass (orchardgrass, perennial ryegrass) and two legume (alfalfa, red clover) hays, harvested in two cuttings in 2 yr, were fed in digestibility, intake and mineral balance trials to wether lambs. Each mixture was fed in ad libitum amounts to six crossbred wether lambs weighing 35 to 45 kg. The effect of increasing proportion of legume in mixtures on dry matter digestibi...

A study was carried out to evaluate nutrient intake and digestibility by West African Dwarf (WAD) sheep fed graded levels of dietary pigeon pea seed meal (PSM). Four diets designated A, B, C and D were formulated to contain 0, 10, 20, and 30% levels of PSM, respectively. Four WAD rams aged between 15 and 17 months and weighing between 16 and 19 kg were used to conduct digestibility study in a 4...

Four West African Dwarf (WAD) grower bucks averaging 6 kg in weight and aged between 5-6 months of age were used in a digestive trial to determine the intake and digestibility of raw or processed pigeon pea seed meal based diets. The diets designated RPBD, SPBD, TPBD and BPBD were formulated from cassava peel, palm kernel cake, brewers dry grain, bone meal and common salt to contain 15% of raw,...

Two levels of grazing intensity were unposed on pasture durtng a spring-time pre-treatment period in two years at Massey University’s Dary Cattle Research Urut. The two grazing intensws were lax (L), 2000-2500 kg DMlha residual herbage mass (RHM) and intense (I) 1000-1500 kg DM/ha RHM. imposed for 2 grazmg rotations. Durmg this period, net herbage accumulation (NHA) on the L wards was approxima...

This experiment aimed to describe the effects of Oregano extract (OE) inclusion into the concentrate fed to dairy heifers on physiological parameters, feeding behavior, intake, and performance. Thirty-two Holstein heifers were randomly distributed into four treatments: C = control, without addition of OE; OE2.5 = 2.5 g; OE5.0 = 5.0 g and OE7.5 = 7.5 g of Oregano extract per heifer/day. Feeding ...

This research was designed to examine the effect of both physical form of the roughage (chaff or ground/pelleted) and or urea supplementation on intake, and digestion by sheep fed barley straw housed at high ambient temperature (40C). The experimental design was factorial 2 x 2 x 4. Sixteen Merino sheep, weighing 26.3 ± 2.1 (SE) kg were randomized into four groups (n=4). Each group was fed one ...

Achieving high dry matter intake (DMI) during early lactation is a major determinant of transition cow management success, as energy balance is tightly linked with reproductive performance (Butler and Smith, 1989) and aspects of health and immunity (LeBlanc, 2010). Although a common notion is that milk yield is the major driver of negative energy balance, several data summaries (reviewed by Gru...
