Improving milk production efficiency by using feed additives.

Farmers can achieve efficient milk production by investing in high quality genetics, but this can depend on the maintenance of high-quality rations. Evidence from trials and practical experience indicates that a reliable and cost-effective way of earning more profit from cows' milk is through optimizing feed with the right additives. This is important for farmers not only to ensure that milk production is profitable, but also to ensure optimal health and well-being for cows. Longer productive life in cows using ß-carotene; A longer productive life is associated with low culling rates and high fertility. Regular breeding can be helped by ß-carotene, a plant pigment that acts as a vitamin to support fertility in dairy cows. It accumulates in the ovaries and participates in the synthesis of the hormones oestrogen and progesterone, both of which are important for ovulation and for safeguarding the embryo. Trials conducted worldwide show that optimal dietary levels of Rovimix ß-carotene increase conception rates and lower the number of abortions. Pregnancy rates for first inseminations in a practical farm trial conducted in France increased by almost 40% in ß-carotene supplemented cows. Calving intervals were reduced by 27 days and milk yield increased by more than 400 kg per cow and lactation. The correct supplementation of ß-carotene in rations leads to an improvement in cows' fertility, health and welfare. Other recorded advantages include more regular ovulation, better foetal health and reduced incidence of retained placenta; as well as better calf health. Health issues such as mastitis can also lead to losing otherwise productive cows. Vitamin E is an important feed additive for the natural control of mastitis. Optimal levels of this vitamin (which cannot be synthesised by the cow) in pre-calving and immediate post-calving rations has been proven to increase immune system resistance to mastitis infection, reducing mammary infections at calving by up to 80%. Clinical and sub-clinical mastitis remain among the biggest drains on dairy profitability (Table 2). Supplementing rations with vitamin E, such as Rovimix E, has proved cost-effective and efficient in combating this serious problem. Correct amounts of vitamin E have also proved to decrease the duration of mastitis in infected cows by as much as 50%. There are also clear advantages gained from boosting dairy cow rations with biotin. Evidence suggests that getting the right additives to optimize feed can lead to increased animal health and well-being, production efficiency and increased income on the dairy farm. Longevity is key for efficient milk production and lifetime performance depends on healthy cows, which depends on their diet. source all about feed)

RESEARCH : VITAMIN D LINKED TO INCREASE FERTILITY IN ANIMALS.

RESEARCH : VITAMIN D LINKED TO INCREASE FERTILITY IN ANIMALS. High levels of vitamin D are linked to improved fertility and reproductive success. Science Daily reports that the study, carried out on a remote Hebridean island, adds to growing evidence that vitamin D - known as the sunshine vitamin - is associated with reproductive health. Experts hope that further studies will help to determine the relevance of the results for other mammals, including people. RESEARCH : VITAMIN D LINKED TO INCREASE FERTILITY IN ANIMALS. Scientists from the University of Edinburgh found that Soay sheep with higher levels of vitamin D in their blood at the end of the summer went on to have more lambs in the following spring. The study offers the first evidence that an animal's vitamin D status is associated with an evolutionary advantage. RESEARCH : VITAMIN D LINKED TO INCREASE FERTILITY IN ANIMALS. Dr Richard Mellanby, Head of Small Animal Medicine at the University's Royal (Dick) School of Veterinary Studies, who led the research, said: "Our study is the first to link vitamin D status and reproductive success in a wild animal population.

RESEARCH : SEAWEEDS AS ANIMAL FEED RESULTS IN EGGS AND BEEF OF BETTER QUALITY.

RESEARCH : SEAWEEDS AS ANIMAL FEED RESULTS IN EGGS AND BEEF OF BETTER QUALITY. Seaweeds can have a pre biotic effect in pig diets and improve egg quality in laying hens. However, high amounts of seaweed in the diet can have an opposite effect. The inclusion rate is therefore important. A report Published in Animal Feed Science and Technology termed : Seaweeds for livestock diets . The nutritive value of seaweeds for ruminants varies widely. It depends on the species, on the composition of the algae (protein, minerals, polysaccharides, phlorotannins) and also on the adaptation of the animal to this particular feed. RESEARCH : SEAWEEDS AS ANIMAL FEED RESULTS IN EGGS AND BEEF OF BETTER QUALITY. A study in the laboratory with rumen fluid from seaweed-fed sheep showed that organic matter digestibility of brown and red seaweeds was very high for brown algae L. digitata, S. latissima and Alaria esculenta species (94%, 97% and 81% respectively) and red algae P.palmata (81%), but was low for other brown seaweeds such as A. nodosum, Fucus serratus and Fucus vesiculosus (33%, 15% and 26% respectively. RESEARCH : SEAWEEDS AS ANIMAL FEED RESULTS IN EGGS AND BEEF OF BETTER QUALITY. In a comparison of brown algae M. pyrifera and Sargassum species, the in situ DM degradability of the former was found to be low (50%) but higher than that of the latter (29%). Crude protein of these seaweeds was found to be rumen-undegradable in situ, but the in vitro trypsic digestibility of their proteins was high, which could make brown algae a good source of protein for ruminants despite their low protein content. RESEARCH : SEAWEEDS AS ANIMAL FEED RESULTS IN EGGS AND BEEF OF BETTER QUALITY. The brown seaweed A. nodosum meal has been shown to increase growth performance in broilers. It didn't matter in which form it was included in the diet (boiled, raw or autoclaved). In another study with green seaweed Enteromorpha prolifera, it was shown that inclusion rate ranging from 2% to 4% provided the best nutrient availability and high apparent metabolisable energy in broilers. This may be attributed to a high level of amylase in the duodenum. It had a positive effect on feed intake, feed conversion ratio and average daily gain while reducing abdominal and subcutaneous fat thickness, thus improving breast meat. Brown seaweed Sargassum species from the Red Sea shore fed to laying hens during 20–30 weeks at 1–12% dietary level had no deleterious effect on body weight, egg weight, egg production, feed conversion ratio and egg quality. Sargassum dentifolium fed raw, boiled or autoclaved at levels of 3% or 6%, was beneficial to egg quality. Green seaweed E. prolifera included at 1–3% resulted in improved egg production and quality: it increased weight, shell thickness, and yolk colour and reduced cholesterol in yolk. It also resulted in a lower E. coli load in faeces, , suggesting better animal health.

SEAWEEDS A NEW OPTION AS ANIMAL FEED.

Seaweeds include brown algae (Phaeophyceae), red algae (Rhodophyceae) and green algae (Chlorophyceae). Seaweeds are valuable alternative feeds for livestock, mostly as sources of valuable nutrients, notably chelated micro-minerals, the availability of which is higher than that of inorganic ones. Brown algae are of lesser nutritional value than red and green algae, due to their lower protein content and higher mineral content; however brown algae contain a number of bioactive compounds. The use of algae as animal feed is promising, as they are sustainable, contain lots of protein and result in more omega 3 in eggs and milk. There is also evidence that they help young cattle grow better. A research in Netherland shows the benefits of algae in feed; Processing algae in animal feed is probably not the first thing that occurs to producers, but the green stuff seems highly appropriate for this purpose. Studies show that using algae as animal feed ensures better quality eggs, milk and possibly meat, and that it boosts growth in piglets, chickens and lambs, among others. "In addition, algae are rich in protein," says Wageningen UR algae expert Rommie van der Weide. "This makes them an interesting alternative to soy, which often has to be transported across long distances – from South America. Algae are produced in photo bioreactors and open ponds, making as much use as possible of the residue streams from a biogas plant. The algae grown here are used in animal feed, mineral licks and a feed supplement for horses. Source;all about feed.
