Estimates of a dairy cow milk production function

ABSTRACT This study aims to determine the effect of the addition of baking soda as a supplement of dairy cattle feed on blood sugar, lactose, and milk production. This study used the dairy cow FH lactation of the 2nd lactation period of 5th month lactation and 6th lactation of 12 with 2-3 years old. Dairy cow FH lactation has a weight of 389.17 ± 27 kg. The treatment used was the addition of baking soda with the level of 0.8% and 1.0%. This study used a ration consisting of soybean meal, corn, brand, meat bone meal, lactoplus and forage grass uganda feed. This study used a complete randomized design consisting of 3 replication and 4 treatments. The data obtained were analyzed using variance analysis and F test at 5% level. The results showed that the addition of baking soda as supplement had no significant effect on blood sugar, lactose, and milk (P> 0,05), but it can increase milk production without supplementation (T0). The conclusion of this research is that the addition of baking soda at the level of 0.8 and 1.0% has no significant effect on blood sugar, lactose, and cow milk production.

Tools And Techniques

In temperate regions of Europe where grass grows for most of the year, grazed pasture is the lowest cost feed for milk production. Grazed pasture can make a contribution to dairy cow feeding systems in other parts of Europe, but is less important. While there are many challenges to maintaining or increasing the proportion of grazed grass in dairy cow diets, there are also opportunities to increase its contribution. Grass use and quality can be challenging for several reasons, including the cow and sward interaction, and factors influencing dry matter intake. Adapting grazing management strategies can provide opportunities for incorporating grazing and perhaps increase grazing in dairy cow milk production systems. Pasture management tools and techniques offer the opportunity to increase herbage use at grazing. While there are many benefits of grazing including economic, environmental, animal welfare and social, there are also the challenges to maintaining grazed pasture in dairy cow diets. The objective of this paper is to present an overview of the challenges and opportunities for grazing in dairy milk production systems.

Abstract In the dairy cow, negative energy balance affects milk yield and composition as well as animal health. Studying the effects of negative energy balance on dairy cow milk production is thus essential. Feed restriction (FR) experiments attempting to reproduce negative energy balance by reducing the quantity or quality of the diet were conducted in order to better describe the animal physiology changes. The study of FR is also of interest since with climate change issues, cows may be increasingly faced with periods of drought leading to a shortage of forages. The aim of this article is to review the effects of FR during lactation in dairy cows to obtain a better understanding of metabolism changes and how it affects mammary gland activity and milk production and composition. A total of 41 papers studying FR in lactating cows were used to investigate physiological changes induced by these protocols. FR protocols affect the entire animal metabolism as indicated by changes in blood metabolites such as a decrease in glucose concentration and an increase in non-esterified fatty acid or β-hydroxybutyrate concentrations; hormonal regulations such as a decrease in insulin and insulin-like growth factor I or an increase in growth hormone concentrations. These variations indicated a mobilization of body reserve in most studies. FR also affects mammary gland activity through changes in gene expression and could affect mammary cell turnover through cell apoptosis, cell proliferation, and exfoliation of mammary epithelial cells into milk. Because of modifications of the mammary gland and general metabolism, FR decreases milk production and can affect milk composition with decreased lactose and protein concentrations and increased fat concentration. These effects, however, can vary widely depending on the type of restriction, its duration and intensity, or the stage of lactation in which it takes place. Finally, to avoid yield loss and metabolic disorders, it is important to identify reliable biomarkers to monitor energy balance.

Holstein Dairy Cow

Milking is the act of removing milk from the udder on purpose to get maximum milk production. A reasonable milking interval will affect the amount of milk production. This research aims to know the extent of the milking time interval affecting Friesian Holstein dairy cow milk production and the interval of milking time that produces the best production and quality of Friesian Holstein. The research method was an experiment using a completely rand randomized with four treatments, namely: treatments 1 was 16:8 hours time delivery interval (TDI) dairy cow; treatments 2: time delivery interval (TDI) 15:9 hours; treatment 3: delivery time interval (TDI) 14:10 hours; treatment 4: time delivery interval (TDI) 13:11 hours. The observed variables are milk production and milk quality. The data were analyzed using verbal if any effect of treatment was done Duncan's distance test. Based on the results and discussion, the milking time interval significantly impacts milk production and water content. Still, it has no significant effect on the density, protein content, and milk fat content, 13:11 hours milking interval time produces the most milk and water content.

ABSTRACT Increased demand of milk is higher along with the increasing number of population, but increased demand of milk is less offset by increased production of local dairy cow milk so that in fulfilling local milk need is still doing a lot of milk import. With the existing of milk demand, livestock farming development of dairy cows can be done in Jember Regency. One of dairy cow farming in Jember Regency is located in Kemuning Lor Village Arjasa District Jember Regency which is the independent farm. Partnership farm in Jember Regency is in Ajung Village Ajung District, Balung Lor Village Balung District and Rowotengah Village Sumberbaru District which are partnership farm with Galur Murni Cooperative. Both livestock businesses experience the same problem which is the lows of milk production so that causes the lows of income received by the farmer. Milk production can increase if the farmer can apply GDFP (Good Dairy Farming Practice) of good dairy cows. This research aimed to (1) find out GDFP implementation, (2) find out the income, and (3) find out cost use efficiency. This research showed that: (1) The level of GDFP implementation of partnership farm was higher than the level of GDFP implementation of the independent farm. (2) Both livestock businesses of partnership and independent farm in Jember Regency is mutual. The amount of income per tail of partnership dairy cows was IDR 8,895,762/year and the net income per tail of independent dairy cows was IDR 11,635,231/year, (3) The cost use efficiency on partnership and independent dairy farm businesses was all efficient. The efficiency value of the R/C ratio of partnership dairy farm business was 1.25 while the efficiency value of the R/C ratio of the independent dairy farm was 1.18.
