The Minister of Agriculture and Rural
Development, Chief Audu Ogbeh, has said cows raised in Nigeria are the
worst milk producers in the world.
He said an average cow in the country
produces less that one litre of milk per day compared to those from
other countries where a cow could produce 100 litres per day.
Ogbeh said this at the 79th anniversary of Ikoyi Club 1938 in Lagos on Thursday
According to the minister, an average
cow in Holland produces a minimum of 50 litres of milk per day, while in
the United States, milk production per cow can rise to over 100 litres.
He said moving cows from place to place
was a major problem affecting meat and milk production in Nigeria,
stressing that the earlier farmers started developing ranches for cows,
the better it would be for the cow market and its entire value chain.
“An average cow in the US drinks an
average of 100 litres of water per day; but in Nigeria, I doubt whether a
cow can get two litres of water per week,” Ogbeh added.
The minister also stated that the
country accounted for 67 per cent of the world’s yam production, adding
that there were more opportunities for Nigeria to grow its share of the
market, valued at $12bn, given the over 50 million hectares of land
lying fallow in the country.
To give the agricultural sector a major
boost, he said the Bank of Agriculture would soon be restructured so
that every local government in the country would have at least a
two-room branch.
Nigeria Natural Health Online's investigations found out that low milk production in cows could be as a result of several factors. In
most years, cooler fall temperatures result in dairy cows increasing in
milk production with cows getting bred back quicker than the warmer
months. Most of these responses are a result of some herds freshening
more cows in the fall, improvements in cow comfort, more time available
to maintain facilities, (where there is ranching) nutrition and reproductive programs, and feeding
programs re-formulated to reflect fall/harmatan/dry season stored feeds. Some
years, dairy cows may not respond as well as previous years with
production being lower than expected. Many different explanations exist
for dairy cows, especially early lactation cows, not milking as well.
Combinations of factors often contribute to the overall situation of
lower milk production and /or reproductive issues.
- Increased average days in milk: As dairy cows enter mid to later lactation, milk production naturally trails off with milk production peaking during early lactation. As the percentage of cows in mid to later lactation increases (increasing days in milk), milk production will be expected to be lower. This contributing factor to lower milk production might seem very obvious, but can provide a possible explanation or partial explanation which can easily be overlooked.
- Longer term effects of heat stress: With the average day time temperatures in the 90’s this past July and August for long periods of time and with hot nights, dairy cows were definitely under heat stress. Although fan, sprinklers, and other ways to accomplish heat abatement are important and need to be used to decrease the effects of heat stress, the heat and humidity still had a detrimental effect on feed intake and fertility. Often times, these detrimental effects on fertility and milk production are seen for 6 to 8 weeks after heat and humidity subside.
- Lower body condition of early lactation cows: In early lactation, dairy cows cannot consume adequate amounts of energy to meet the energy needs for milk production and maintenance of the cow herself. As a result, early lactation cows are said to be in negative energy balance and rely on body stores of fat or adipose tissue to support the additional amounts of energy needed to support milk production they cannot consume. If these stores are not present or are mobilized too quickly, cows often times will produce the amount of milk equal to the amount of energy they can consume. In other words, they will not milk as well as they could have or peak as high in milk production. Thin early lactation cows often are related to cows calving thinner than normal or metabolic disorders related to the transition back into the milking herd that result in cows going off feed and dropping in body condition quickly.
- More cows in the milk herd: Often-times cows are added to the milking string to improve cash flow without making accommodations for increased bunk space (hay, silage, and/or TMR) and/or resting space. Overcrowding at the feed bunk can decrease feed intake especially in fresh and early lactating cows resulting in lower milk production. Sometimes overcrowding with other contributing causes can result in lowered milk production even when it appears that no feeding and management practices have changed.
- Thinner cows at calving: Dairy cows are the most efficient and cost effective at putting on body condition or fat stores when they are milking versus when they are dry. Thus, our management programs are geared toward putting condition on cows in mid to later lactation, having them in the proper condition at dry off, and maintaining that condition during the dry period. Summer temperatures can decrease or stop the growth of pasture grasses and legumes, thus decreasing forage availability and sometimes dry cows lose weight or body condition if alternative forages are not provided. In addition, with higher grain costs, dry cows may not have been provided adequate amounts of grain to maintain body condition if forage quality was low. Dry cows that calve too thin will not have the energy reserves to milk well this next lactation, especially during early lactation.
- Rebalanced rations to reflect quality of forages currently being fed: The quality and thus nutrient content of forages change between crop year, cuttings, and type of forage. In addition, yearly differences exist in the digestibility of forages by the rumen bacteria. These changes in NDF digestibility can greatly affect the amount of energy cows and, more importantly, bacteria receive from the forages and other feeds consumed. A current forage analysis should be used to balance rations numerous times each year. Monthly ration balancing or review of rations being fed is recommended for the most economical and efficient use of forage resources. With the wide swings in commodity prices, this reevaluation becomes even more critical.
- Limited grain in corn silage: With this summer’s drought and high temperatures during corn pollination, corn silage may contain limited amounts of grain and the amount of corn silage available to be fed may be limiting. These changes in the quality and quantity of corn silage potentially decrease the amount of energy coming from these forages. To try and compensate for the decreases seen in grain content, more energy needs to be added to these rations in the form of ground corn grain or other byproducts, increasing the cost to feed the milking herd. At the same time, these alterations may alter the digestibility of starch and fiber fractions of the diet and the bacteria may not have the identical types and digestibility of energy sources compared to diets containing higher grain, corn silage diets. Bottom line, when the bacteria do not get adequate amounts of energy at specific times, they produce less end products cows can use to make milk and, as a result, milk production may be reduced. Sometimes, these diets need to be tweaked over time to get the best combination. Working with your nutritionist and fine tuning these diets over time is the best way to achieve the desired results. Blending last year’s corn silage with this year’s has helped cows adjust to the differences and bridge the gaps. This may offer one explanation of why some herds have been able to hold milk production similar to previous years.
- Changes in forages being fed: With reduced corn silage yields and multiple dry years, some dairy farmers have opted to include silage made from forage sorghum into diets for the milking herd. Granted these varieties most likely have higher digestibility than older varieties of forage sorghum, but they still contain less energy than higher-yielding, energy dense corn silage. Can they work well in rations for milking cows? Yes, but your nutritionist needs to make sure the bacteria have the nutrients they need (carbohydrates and nitrogen or amino acid source) at the correct time. Thus, old recipes for grain mixes may not always work and they may or may not support 70-80 lb herd averages.
- Problems when transitioning cows back into the milking herd: A smooth transition of cows back into the milking herd is critical to getting dairy cows to milk well in early lactation and rebred. Often-times, minimizing stress, caused by limited feed bunk space (recommend 36 inches per cow), cow comfort (provide effective heat abatement) and resting space, 3 weeks before calving through 3 weeks after calving, is the starting point. Diets need to contain adequate amounts of effective fiber or chew factor for proper rumen fill, minerals and vitamins to prevent subclinical (no visible signs but blood calcium is low) milk fever, and adequate but not excess amounts of energy and protein. Subclinical problems are often not detected and can cause issues in fresh cows that result in decreased feed intake before or after calving, rapid losses in body condition, and decreased milk production and reproductive performance.
- Other disease issues: Clinical cases of diseases, such as mastitis or metritis, can decrease milk production and reproductive efficiency. In addition, mycotoxins in feeds (forages as well as grains) also can decrease feed intake in herds and may affect performance. However, before dairy farmers blame mycotoxins for decreases seen in milk production and/or reproductive performance, other aspects of their feeding and management program should be examined and eliminated as potential causes first.
- In Nigeria, where ranching facility is not readily available to the vast majority of the cow owners, animal health expert say the country is still far behind in global cow milk production as most of the herdsmen who manage the cows in the country do not possess the professional knowledge needed to mentain a healthy dairy production.
