Roughages for Dairy Cows L. Smith,' W. Kelley,' and George E. Hawkins' Tracy sorghum produces good yields of forage and has created much interest as a silage crop for dairy cattle. Also, Johnsongrass, a commonly grown forage in the Black Belt area of Alabama is used extensively as a hay for dairy cows.
Small grain straw should not be used in rations for dairy cows. With the necessary supplementation, straw can be used to a limited extent in the feeding of replacement heifers.
Small grain straw is often upgraded by treating it in an oven or in a stack with ammonia. 39 The roughages and concentrates contain most of the minerals required by cattle and buffalo. Supplements are necessary where the quantities in the feed fall short of requirements.
40 A good mineral supplement should make up for the shortfall of minerals in feeds. Sixteen lactating Holstein x Red Sindhi cows were used in a 4 x 2 randomized block design to determine the effects, if any, of feeding four kinds of roughages supplemented with two levels of concentrates on cow's milk production and composition, body weight gain and physiological responses (body temperature, respiratory rate and pulse rate).Author: A.K.
Simanjuntak, J.R. Escano. Effective supplementary feeding of concentrates is critical to the success of all dairy farms. This book is a substantially revised edition of 'Feeding Concentrates: Supplements for Dairy Cows' DRDC It focuses on feeding concentrates to pasture fed cows to achieve high milk production per cow per hectare, and will assist farmers to decide which supplements give the best.
This book presents strategies for feeding energy and protein supplements to pasture-fed dairy cows and examines the potential economic benefits.
Effective supplementary feeding of concentrates is critical to the success of all dairy farms. This book is a substantially revised edition of 'Feeding Concentrates: Supplements for Dairy Cows' DRDC Dairy cows (and all other ruminants) have the capacity to convert roughages and other by- products from the human food industry, otherwise useless waste products, into valuable products like milk and meat.
It has been reported that local buffaloes and cows digest concentrates and good quality roughages, like berseem hay, equally well. With poor quality roughages like rice straw however, the buffalo excelled the cow in digesting DM and CF (El-Ashry ; Saied Mahmoud, personal communication).
Concentrates provide the essential extra energy and protein dairy cows need on top of forages to support modern production levels. Concentrates must be carefully selected to balance the specific nutrients provided by the forages available for the most efficient ruminant digestion, greatest cow productivity and most cost-effective herd performance.
P T C Johnson, Meadow Feeds. There is a great variety of concentrates suitable for feeding to dairy cattle, ranging from the individual ingredients which can be used on the farm to mix rations, to the ready-mixed commercial compound feeds.
Complete Rations for Dairy Cattle. Methods of Preparation and Roughage-to-Concentrate Ratios of Blended Rations with Corn Silage I ABSTRACT Treatment means for dry matter intake, milk production, fat-corrected milk, milk fat test and body weight gains did not differ significantly when rations containing comparable proportions of corn silage and concentrate mixture (30% roughage and 70%.
Concentrates are grain-type feeds, beet-pulp, waste bread, etc. Roughages are the standard feed for all cattle operations; concentrates are used for fattening up cattle for slaughter. concentrate feeding to the ﬁnal ﬁnishing period ( days for steers and heifers and up to days for bulls).
With ad-lib concentrates a high rate of gain (kg). Dairy Cattle Feeding and Nutrition was designed to provide information needed by those interested in the feeding and nutrition of dairy cattle.
It contains basic information for students in courses on feeds and feeding, dairy cattle production, and animal nutrition.
Practical considerations in feeding dairy cows Written by Maurice Rangoma. The objective of feeding dairy cows should be to attain a high level of milk production.
Roughages alone cannot provide all the required nutrients, especially in early lactation. Concentrates are therefore included to supplement roughages.
Up to 3kg DM/dry cow/day (15 kg fruit/cow/day) can be fed to dry stock but this needs to be reduced to 5kg fruit/cow/day if the fruit is ripe. milking cows have been fed up to kg DM/cow/day without obvious problems but only where cows have a high intake of pasture ( kg DM/cow/day).
In daily practice, dairy cattle may be exposed to complex mixtures of mycotoxins originating from pre- and postharvest contamination of roughages, silage and concentrates.
In particular silage has been identified as a source of different microbial toxins, which may impair animal health and productivity. Dairy cows fed equal amounts of concentrate (fixed daily rate: kg DM/cow) were compared to cows supplemented with concentrate according to their lactation stage as follows:, and Dr.
Mike Hutjens discusses concentrates and its role in dairy cattle rations. 6 – Feeding management of the milking herd 67 differences between basal roughages and supplement type or large amounts (say 5 kg DM/cow/day or more) of supplement are fed.

Feeding the Dairy Cow Key fact Energy, not protein or minerals, is the most limiting nutrient in dairy production systems. If animals are not milking as well as expected, or milk protein is low or cows are losing excessive condition, energy is the ﬁrst nutrient to check.

By-product Roughage Feedstuffs for Dairy Cattle 2 substitute for 10 to 20% of the other roughages in the ration. COARSE GROUND CORN COBS Coarse ground corn cobs are similar to cottonseed hulls in feeding value but slightly less palatable.
They are used primarily as a roughage extender in rations rather than as a major roughage source. Concentrates in rations for dairy cows increase the energy density of the ingested dry matter, but also the supply of protein (nitrogen) and further nutrients like minerals and vitamins.
Furthermore there is a differentiation between concentrates like cereals (own production) and those from the feed industry (ingredients like rapeseed meal or compound feeds for supplementation of dairy cow. The better the quality of the roughages, the better the concentrate must be to effect an improvement in the overall nutrient intake of the cow.
A simple example: In the "Blue Book" Feeding and Management of Dairy Cattle in Natal (Bredon & Stewart, ), an attempt was made to take into account all the factors affecting a cow's feed. Concentrates (grains) usually account for % of the energy obtained from feed in cattle, 85% in pigs and % in sheep and goats.
Starch content in grains is approximately 45% in cereals and up to 72% in maize grain. 4- TYPES Dairy Cows Rations: Rations fed to dairy cows which are grouped according to cow's weight and daily milk yield. Non-dairy cattle rations: Dry pregnant cows ration.

All you need to know about feeding your cow for maximum productivity Friday August 7 Sarah Mwangi feeds her dairy cows on Ma on her farm in Ngong, Nairobi.
Whether a dairy is milking cows or 1, cows, herd replacement expenses represent a significant cost of doing business. Along with that, a first-calf heifer spends her first lactation paying for herself – not making you any money. The cost of replacements is typically second only to milk cow.
When cattle are fed such roughages produced on low-calcium soils, or when finishing cattle are fed high-grain diets with limited nonlegume roughage, a calcium deficiency may develop. Because lactating beef cows do not produce nearly the amount of milk that dairy cattle do. CATTLE CARE & HANDLING GUIDELINES 9 Cows • It is desirable for cows to have a BCS of at least 4 before the calving season.
• During the calving season, cows should be checked regularly for calving difficulties. First-calf heifers may require more frequent observation and care. • Producers should consider contacting a veterinarian for.
Beef cows are cows raised to live with minimal management, and they (beef cows) can raise calves. On the other hand, dairy cows are raised to produce milk but not calves. Cattle are usually raised as livestock either for meat (beef or veal) or for milk, and for hides for making leather.
Most cows cannot maintain normal milk fat levels if concentrate intake from all sources (mixtures, top-feeding, etc.) exceeds percent of bodyweight daily on an air-dried basis. Whenever rations fed vary appreciably from the usual, it is more important than ever to test forages and obtain professional help with nutrition balancing.

Grazing crop residues is a source of roughages to feed cattle. Young cows and heifers are still growing and require more feed than mature animals. and reproduction of dairy cattle. Cat- tle cannot long survive and reproduce on a poor forage even though the tenebest quality of grain ration may be arefed at the same time.
The reason is that roughages contain minerals and vita- mins that dairy cattle need and weak,that concentrates normally do not supply. Harvested forages usually arc crops. expense to the dairyman. For dairy cattle to produce economically, at a high level, they must receive a well-balanced ration.
Roughages alone are inadequate to meet the nutritional needs of high-producing animals. Concentrates are needed to supplement the roughages. Dairy cattle should be fed individually whenever possible. Their. The aim of the present on-farm study was to analyse vitamin content in roughage at harvest and during storage and to analyze milk vitamin content when feeding the roughage to dairy cows.
Roughages.Typically, cattle tolerate hay that is dustier than what horses can handle. This livestock is even able to eat slightly moldy hay without any problems.
If you are feeding pregnant cows, pay attention to mold that does develop, as some varieties cause abortion. Young calves, dairy cows, and mature beef cattle require different qualities of hay.c.
