1. Equine Nutrition Feed Quality and Feed Analysis

2. Feed Quality Quality of feed affects its value for animal nutrition. Quality factors include –palatability –nutrient content. Improper harvesting or handling will reduce quality.

3. Harvesting Hay for Quality Quality of hay is affected by harvesting and handling methods. Hay with more stem & fewer leaves is of lower quality. –the leaves contain the most nutrients and are the easiest to digest.

4. Harvesting Hay for Quality Legume (leafy) hays will shatter easier than grass hays. Moisture content must be reduced. Factors affecting moisture content include –humidity and movement of air, –fineness of forage –how compact the bale is.

5. Moisture content must be reduced without spoiling or loosing nutrition value. Factors affecting moisture content include –humidity and movement of air, –fineness of forage –how compact the bale is.

8. Harvesting Quality Hay Loss of quality during harvesting: –Shattering When forages get too dry, leaves tend to shatter. –Leaching Forage that is rained on while curing will suffer loss of quality by leaching –Bleaching Bleaching occurs when the forage has cured to long in extremely hot temperatures.

9. Producing Quality Silage When high moisture crops are stored under anaerobic, without air, conditions, a fermentation process occurs that produces silage. Crops may be stored is vertical or horizontal silos. Vertical silos require less land, less spoilage and require less labor for unloading.

55. Example… A bred mare requires a 13% protein ration. You have available- 1-Corn with 9% protein 2- cotton seed meal with 40 % protein Find the number of pounds of corn and CSM needed to make a 100lb ration. F. Balance a ration

56. Your turn… F. Balance a ration A 1400-pound Mare in the second trimester of pregnancy needs 8% protein. She is given grass hay (6% protein) and soybean meal (49.6% protein) Calculate how many pounds of each feed is required to mix a 100 pound ration of feed 8% CP feed

57. Bell work… F. Balance a ration A 1400-pound cow in the second trimester of pregnancy needs 8% protein. She is given grass hay (6% protein) and soybean meal (49.6% protein) Calculate how many pounds of each feed is required to mix a 100 pound ration of feed 8% CP feed

58. Nutrition Assn Checkoff F. Balance a ration Nutrition Wordsearch_____/5 Pearson Square Practice wkst_____/20 Feed Label 101 Packet_____/20 Unit 7: Feed Additives:_____/20

59. Pearson Square A 1400-pound gelding used for work needs 6.9% protein. He is given 23.3 lbs of feed most of which is grass hay at 5.5% protein. How many pounds of soybean meal (49.6% protein) should the gelding be given to make sure he receives 6.9% protein?

60. Sample Problem Formulate 600 lbs of a 26% CP ration using CSM (54% CP) and Barley (8% CP).

61. What’s Being Asked? You have 2 different feeds on hand, each containing a certain amount of protein. But for your purposes, neither will suffice. You need to mix them to make a new feed of a specific amount protein. And you need to make 600 lbs of the new feed.

62. Solving…..using a Pearson Square These types of problems are easy….but you have to use the Pearson Square. –1 st set up the square (this will be the same every time:

63. 2 nd, label the square: Feed #1 goes here Feed #2 goes here Feed #1 also goes here Feed #2 also goes here With its %CP The %CP you want goes here

64. This is what it should look like: CSM 54% Barley 8% 26% CSM Barley

65. 3 rd, some simple subtraction…one feed at a time. Subtract going diagonally: #1. CSM (54) – 26 = 28% Barley: CSM 54% 26% Barley 8% CSM 28 parts Barley

66. 4 th, do the same calculation for the second feed. Subtract on the other diagonal: Barley (8%) – 26 = -18 % CSM. But just use the absolute value….ignore the negative sign: CSM 54% Barley 8% 18 parts CSM 28 parts Barley 26%

67. 5 th, add up total parts CSM and Barley for the new feed: CSM 54% Barley 8% CSM 18% Barley 28% + 46 total (18 + 28 = 46) 26%

68. Wait….What’s going on? We just calculated what percent of our new ration will be CSM and Barley: of the total amount of new feed, it will be 28 parts Barley and 18 parts CSM. Now we have to determine how many pounds of each this correlates to. Once we know that, we can mix our feeds together.

69. So from the square, we know that in our final feed we need: –28 parts Barley –18 parts CSM We also know from the problem that we need 600 lbs of the new feed. –This is the easy part!

70. Just convert parts to %: Remember the formula for percentage: –Part/whole x 100 = %part Barley: –28 parts / 46 total parts x 100 = 60.87% CSM: –18 parts / 46 total parts x 100 = 39.13 %

71. Then convert % to lbs: Now we know what % of final feed will be barley and CSM, and from the problem, we know we want 600 total lbs of feed. We just need to figure out how many lbs of each this means! –Barley: 600 lb x.6087 = 365.22 lbs! –CSM: 600 lb x.3913 = 234.78 lbs! –This is your answer! You need to mix 365.22 lbs barley and 234.78 lbs CSM to make your mix!

72. Bell Quiz: 1.List all 6 essential nutrients that an animal should have 2.Name 3 factors that effect an animal’s nutrition needs 3.What is the definition of a roughage? Give an example. 4.What is the definition of a concentrate? Give an example.

73. Bell Quiz: 1.What is the definition of “free feeding?” 2.What is the definition of “scheduled feeding?” 3.Name a pro and a con for each method of feeding 4.Compare and contrast roughages and concentrates

74. List each species of animal you have ever owned and tell me what you feed it and how much it gets daily Bell Quiz:

75. Let’s Check the Answer Barley: we determined 365.22 lbs needed; and from the problem we know that our barley is 8% CP; –365.22 x 0.08 = 29.22 lb CP CSM: we determined 234.78 lbs needed; from the problem we know CSM is 54% CP; –234.78 x 0.54 = 126.78 These two answers should add to give the percent CP we were looking for: –29.22 + 126.78 = 156 –156 lb CP / 600 total lb feed x 100 = 26% CP

76. Ready for another one? A zelephant is on a feed that requires a ration containing 55% TDN. The TDN of two feeds, alfalfa hay and corn, are 89% and 22%, respectively. Determine the amounts of each feed necessary (in units/300 lbs) to meet the TDN requirement of the zelephant.

77. Answer Alfalfa Hay 89% Corn 22% 33 parts Alfalfa Hay 34 parts Corn 55% 67 total parts Alfalfa: 33 parts / 67 total x 100 = 49.25%; 300 lbs x.4925 =147.75 lbs Corn: 34 parts / 67 total x 100 = 50.75%; 300 lbs x.5075 = 152.25 lbs Check the answer: alfalfa: 147.75lbs x.89 TDN = 131.49 lb TDN corn: 152.25 lbs x.22 TDN = 33.49 lb TDN 131.49 + 33.49 = 164.98 total TDN / 300 lb feed x 100 = 55% TDN
