I had struggled with weight loss all my life, I have a prediabetes condition and stress eating. Pietrzykowska and featured in Your Weight Matters Magazine. Thus, inorganic sources of calcium, such as calcium carbonate or dicalcium phosphate, must be added to the rations of lactating dairy cows. Multiple family members can log in and view meal history, make payments and manage their accounts. Graduates from recognized institutions in Ontario with the same program learning outcomes as the Humber program may be eligible for admission into an advanced semester. Animals most likely to benefit from supplements selected for high RUP proportions are those with relatively high protein requirements and relatively low rates of feed intake. Additionally, the office staff is friendly and helpful.
The crude protein system considers only the total amount of dietary protein, or protein equivalent from nonprotein nitrogen sources. The crude protein system is relatively simple to use and has provided a traditional means of formulating dairy cow rations. Recommended Minimum Dietary Protein Concentrations for Dairy Cows at Various Levels of Production a provides general guidelines for the required crude protein concentration of diets for large- and small-breed dairy cattle at various levels of production.
It can be used for general evaluations of the protein adequacy of dairy diets. The metabolizable protein MP system is more complex than the crude protein system, and it was developed in recognition of the fact that not all crude protein provided to cows may be available for absorption as amino acids.
Calculation of dietary metabolizable protein concentrations generally requires specialized software. MP refers to amino acids absorbed from the small intestine and available for metabolism. MP in ruminants is derived from two sources: Protein escaping rumen degradation is referred to as rumen undegraded protein RUP , while protein that is broken down in the rumen is referred to as rumen degraded protein RDP.
Both sources are important and must be considered in diet evaluation and formulation. RUP passes unaltered through the rumen and forms a direct source of protein for intestinal digestion and amino acid absorption.
Nitrogen from RDP, in contrast, must be incorporated into newly synthesized microbial protein before it will provide amino acids available for intestinal absorption. The efficiency with which RDP is recovered as microbial protein depends on the growth rate of the rumen microbes, which in turn depends on the supply of fermentable energy sources in the rumen.
Thus, diets with sufficient RDP and relatively high energy concentrations will result in high yields of microbial protein, which will become available for intestinal digestion and absorption as MP. In general, specialized software, commercially available, is necessary to formulate dairy diets using the MP system. Even with such software, many variables must be estimated with uncertainty.
Therefore, calculations of MP supply must be recognized to be approximations. The relationship of dietary protein intake to metabolizable protein supply. The two branch points indicated by 1 and 2 constitute the major variables relating the dietary crude protein supply to the metabolizable protein supply.
The first branch point represents the proportion of protein that is degraded in the rumen. This branch point is influenced by inherent properties of the protein and the rate of ingesta passage through the rumen. The second branch point represents the proportion of nitrogen from degraded protein that is recaptured as microbial protein. This is influenced by the microbial growth rate, which depends on the supply of rumen available energy.
Nitrogen that is not recaptured as microbial protein is absorbed from the rumen as ammonia and converted to urea by the liver. Some urea is recycled back to the rumen, but a large portion is excreted in urine.
In general, feeds with high moisture and high protein concentrations, eg, legume silages, will have a high proportion of RDP. In contrast, feeds that have been processed and especially those that have undergone drying will have relatively high proportions of RUP. The proportions of RUP and RDP in diets and individual ingredients are not fixed but can vary somewhat depending on intake rate.
At high rates of feed intake, the rate of feed passage through the rumen is high; thus, there is less opportunity for rumen protein degradation than with the same feeds at lower intake rates. Therefore, on the same diet, RUP proportions are higher in animals with high rates of feed intake than in those with low rates of feed intake. Animals most likely to benefit from supplements selected for high RUP proportions are those with relatively high protein requirements and relatively low rates of feed intake.
Cows in very early lactation and young, rapidly growing heifers are the primary examples. Supplements formulated for high RUP proportions are commonly known as rumen bypass protein supplements; however, even with these types of supplements, some portion of the protein is degraded in the rumen.
Along with overall protein requirements, dairy cows, as all other animals, have specific amino acid requirements. However, evaluating dairy cow diets relative to amino acid requirements is more difficult than making similar evaluations of diets for monogastric animals.
This is because the amino acid supply for dairy cows and other ruminants is a combination of the amino acids provided by the microbial protein and the RUP. Microbial protein has an excellent amino acid profile, and diets with a large supply of microbial protein typically meet amino acid requirements if MP requirements are met.
In some cases, however, high-producing dairy cows may benefit from the selection of RUP sources with specific amino acid profiles, or from adding rumen-protected forms of specific amino acids. Software is available that estimates the amino acid supply for dairy cows on different diets.
The first limiting amino acids in typical dairy cow diets are lysine and methionine. With typical feedstuffs, if the MP requirement is met and the dietary lysine: The availability of high-quality water for ad lib consumption is critical. Insufficient water intake leads immediately to reduced feed intake and milk production. Water requirements of dairy cows are related to milk production, DMI, ration dry matter concentration, salt or sodium intake, and ambient temperature.
Various formulas have been devised to predict water requirements. Two formulas to estimate water consumption of lactating dairy cows are as follows:. Water consumed as part of the diet contributes to the total water requirements; thus, diets with higher moisture concentrations result in lower FWI. Providing adequate access to water is critical to encourage maximal water intake.
Water should be placed near feed sources and in milking parlor return alleys, because most water is consumed in association with feeding or after milking. For water troughs, a minimum of 5 cm of length per cow at a height of 90 cm is recommended. One water cup per 10 cows is recommended when cows are housed in groups and given water via drinking cups or fountains.
Many cows may drink simultaneously, especially right after milking, so trough volumes and drinking cup flow rates should be great enough that water availability is not limited during times of peak demand. Water troughs and drinking cups should be cleaned frequently and positioned to avoid fecal contamination.
Poor water quality may result in reduced water consumption, with resultant decreases in feed consumption and milk production. Several factors determine water quality. Total dissolved solids TDSs , also referred to as total soluble salts, is a major factor that refers to the total amount of inorganic solute in the water.
TDS is not equivalent to water hardness, which is a measure of the amount of calcium and magnesium in water. Water hardness has not been shown to affect dairy cow performance. Water may be refused when first offered to animals or cause temporary diarrhea. Animal performance may be less than optimum because water intake is not maximized. Pregnant or lactating animals should not drink such water.
May be offered with reasonable safety to animals when maximum performance is not required. These waters should not be offered to cattle. Other inorganic contaminants that affect water quality include nitrates, sulfates, and trace minerals. General recommendations for sulfate concentrations in drinking water are Concentrations of Potentially Toxic Nutrients and Contaminants in Drinking Water Generally Considered Safe for Cattle lists potential elemental contaminants of drinking water with upper-limit guidelines.
Calcium requirements of lactating dairy cows are high relative to other species or to nonlactating cows because of the high calcium concentration in milk.
Thus, inorganic sources of calcium, such as calcium carbonate or dicalcium phosphate, must be added to the rations of lactating dairy cows. For the first 6—8 wk of lactation, most dairy cows are in negative calcium balance, ie, calcium is mobilized from bone to meet the demand for milk production. This period of negative calcium balance does not appear to be detrimental so long as there is sufficient dietary calcium such that bone reserves can be replenished in later lactation.
The availability of dietary calcium for absorption varies with dietary source. Dietary calcium from inorganic sources is generally absorbed with greater efficiency than that from organic sources. Furthermore, cows in negative calcium balance absorb calcium more efficiently than cows in positive calcium balance.
When calculating calcium requirements, newer nutritional models take into account the variability in calcium availability from different sources.
This approach makes it difficult to generate general recommendations for total dietary calcium concentrations across various diets. Generally, diets with large portions of forage from legume sources will have minimum calcium concentration requirements in the range of 0. Two approaches are taken with respect to the calcium supply for dry cows, each with the objective of preventing milk fever, or parturient paresis see Parturient Paresis in Cows.
One approach is to place cows in a calcium-deficient state during the last 2—3 wk of gestation; the rationale is to stimulate parathyroid hormone secretion and skeletal calcium mobilization before calving. This makes calcium homeostatic mechanisms more responsive at the time of parturition, allowing cows to maintain serum calcium concentrations during lactation.
This approach requires diets with calcium concentrations near 0. Such diets are difficult to formulate with available feedstuffs while still meeting other nutritional requirements. Another approach is to feed an acidifying diet, usually referred to as a diet with a low or negative dietary cation-anion difference DCAD. The low-calcium diet approach is not additive with the DCAD approach to milk fever prevention. When low-DCAD diets are fed, total dietary calcium concentrations should be near 0.
Phosphorus nutrition for lactating dairy cows has dynamics similar to those of calcium. The efficiency of phosphorus absorption is affected by physiologic state and dietary source. As is the case with calcium, most dairy cows in early lactation are in negative phosphorus balance. Phosphorus mobilized from bone early in lactation is replaced during later lactation when feed intakes are higher.
Young animals and animals in negative phosphorus balance absorb phosphorus more efficiently than do older animals or animals in positive phosphorus balance. Phosphorus from inorganic sources is more available than that from organic feed sources.
Judiciously balancing diets to meet, but not exceed, phosphorus requirements is important for dairy cow performance and environmental stewardship. Excess phosphorus excreted in feces is one of the major pollutant risks associated with livestock production.
