Abstract Several beneficial effects have been observed in the gastrointestinal tract in response to the provision of short-chain fatty acids such as butyrate, including the improvement of gut barrier function, stimulation of epithelial cell proliferation and gastrointestinal homeostasis. By improving gut barrier integrity, it is possible that less energy would be spent mounting an immune response against infiltrating xenobiotic compounds, allowing for more energy to be partitioned towards productive activities, such as milk synthesis. Previous work has demonstrated that gluconic acid and its salts have a prebiotic effect in the lower gut in monogastric animals, where it acts as a substrate for butyrate synthesis, with new data suggesting a similar response in dairy cattle. The objective of this study was to evaluate the effects of supplementation of a fat-embedded calcium gluconate product on milk production in dairy cattle. Lactating heifers (n = 22) and cows (n = 53) were offered either a total mixed ration supplemented with 0.07% fat-embedded calcium gluconate or a negative control ration over the course of a full lactation. Milk production and dry matter intake were recorded daily, while milk composition was determined at regular intervals over the lactation. Cows receiving the supplement displayed significant (P ≤ 0.046) increases in milk and component yields, while consuming 1 kg DM/d more during lactation compared to control. Heifers receiving the supplement displayed decreased (P ≤ 0.044) yield of milk fat and fat-corrected milk, 0.09% increased milk protein content, and decreased feed efficiency. Overall, the results in multiparous animals are consistent with previous work examining calcium gluconate. Further work is needed to characterize the differential response in heifers.

Abstract Fat-embedded calcium gluconate fed as a dietary supplement has previously been shown to increase milk and component yields in lactating dairy cattle in controlled experimental settings. These responses are thought to be due to improvements in gut barrier function and health driven by increased butyrate supply from the fermentation of calcium gluconate in the hindgut. The objectives of the current study were to validate the effects of a fat-embedded calcium gluconate supplement offered during late gestation and early lactation on milk production and milk component yields in a commercial setting. From April to December 2019, 151 multiparous Holstein-Friesian dairy cows were assigned to one of four treatment sequences in a randomized complete block design within a 2 x 2 factorial design (negative control or supplement prepartum, and negative control or supplement postpartum). Outcomes pertaining to milk production, component yields and health parameters were recorded for the first 100 days of lactation. Yields of milk and all components increased (P ≤ 0.045) in response to postpartum supplementation, in agreement with previous studies. Milk protein content was 0.03% lower (P = 0.003) in animals receiving the supplement prepartum. Additionally, prepartum supplementation diminished the lactation performance response relative to animals receiving supplementation in the postpartum period only; lactation performance was partially ameliorated by subsequent postpartum supplementation. Overall, these results support previous work examining the lactation performance response to fat-embedded calcium gluconate supplementation in dairy cattle. Future controlled studies examining the effects of prepartum supplementation on subsequent lactation performance are warranted.

Background: Children are the precious gift from the Almightily Allah and breast milk is an ideal product given to the human being by nature to fulfill all requirements of the offspring until they are matured enough to take adult food. Objective: To assess the services provided for lactating mothers at lactation management centre in selected tertiary level hospitals. Materials and Methods: This cross sectional study was conducted among 100 Lactating mothers who were selected conveniently and were interviewed by pre-tested semi-structured questionnaire and an observational checklist. Collected data were processed and analyzed using SPSS (Statistical Packages for Social Science) software. Results: Lactation management centre (LMC) is supervised by a consultant and separate room is allotted in both out-patient and in-patient departments. Mothers came with lactation problems were more likely in the first month of the baby (73%) and feeling of not enough milk production was common (49%).Highly significant relationship was found between breast problems of lactating mother and age of child (p<0.001). About 84% respondents received practical demonstration on position and attachment of the baby during lactation. About 91% respondents got dietary advice for enough breast milk production, 75% got dietary advice regarding their child’s weaning food chart and69% got health education. Maximum mothers were informed about LMC by doctor & nurse (82%). Conclusion: Information about LMC services should be disseminated across the country. Lactating mothers should be familiarized with LMC and public awareness should be enhanced for effective management of breastfeeding problem to promote, protect and support the breastfeeding.

In a four year grazing trial with dairy cows the application of 5000 kg lime/ ha (applied in two applications of 2500 kg/ha in winter of the first two years) significantly increased annual pasture production in two of the four years and dairy production in one year. In three of the four years lime significantly increased pasture growth over summer/autumn with concurrent increases in milk production. In the last year of the trial lime had little effect on pasture growth but a relatively large increase in milkfat production resulted. A higher incidence of grass staggers was recorded on the limed farmlets in spring for each of the four years. In the second spring immediately following the second application of lime significant depressions in both pasture and plasma magnesium levels were recorded. By the third spring differences in plasma magnesium levels were negligible but small depressions in herbage magnesium resulting from lime continued to the end of the trial. Lime significantly raised soil pH, Ca and Mg levels but had no effect on either soil K or P. As pH levels of the unlimed paddocks were low (5.2-5.4) in each autumn and soil moisture levels were increased by liming, these factors may suggest possible causes for the seasonality of the pasture response to lime

I am a 30-year-old sharemilker on my parent's 600 cow developing farm near Blackball on the western side of the Grey Valley. Earlier this year I competed in the National Young Farmer of the Year competition and finished a close third. So what is information? There are two types of information that I use. There is data gathered from my farm to help fine tune the running of the day to day operations on the farm And directional information This is the information that arrives in papers and directs the long-term direction and plans of the farm and farming businesses. Due to the variability in weather on the Coast there is a greater need to monitor and adjust the farming system compared to an area like Canterbury. This was shown last year (2001/02) when the farm was undergoing a rapid period of development and I was under time restraints from increasing the herd size, building a new shed as well as developing the farm. The results of the time pressure was that day to day information gathering was lower resulting in per cow production falling by 11% or around $182 per cow. So what information was lacking that caused this large drop in profit. • Pasture growth rates • Cow condition • Nitrogen requirements • Paddock performance • Milk production • Pre-mating heat detection As scientists and advisers I hear you say that it is the farmer's responsibility to gather and analyse this information. You have the bigger topics to research and discover, gene marking, improving pasture species, sexing of sperm and ideas that I have not even contemplated yet. This is indeed very valuable research. Where would farming be without the invention of electric fences, artificial breeding and nitrogen research? But my problem is to take a farm with below average production to the top 10% in production with the existing technology and farming principles. I have all the technical information I need at the end of a phone. I can and do ring my consultant, fertiliser rep, vet, neighbour and due to the size and openness of New Zealand science, at present if they do not know I can ring an expert in agronomy, nutrition, soils and receive the answer that I require. I hope that this openness remains as in a time of privatisation and cost cutting it is a true advantage. I feel that for myself the next leap in information is not in the growing of grass or production of milk but in the tools to collect, store and utilise that information. This being tied to a financial benefit to the farming business is the real reason that I farm. Think of the benefits of being able to read pasture cover on a motorbike instantly downloaded, overlaying cow intake with milk production, changes in cow weight, daily soil temperature and predicted nitrogen response. Telling me low producing cows and poor producing paddocks, any potential feed deficits or surpluses. This would be a powerful information tool to use. The majority of this information is already available but until the restraints of time and cost are removed from data gathering and storage, this will not happen.

The study was carried out on 19 ewes of local Awassi sheep and 12ewes local Arabi sheep in the Al-kafeel sheep station Karbala, to determine the effect of breed and some non-genetic factors such as (sex of the lamb, type of birth, age and weight of ewes at birth) on daily and total milk production and lactation period and some of milk components (fat, protein and lactose). The results showed that a significant effect (P <0.05) of the breed on milk production traits where Awassi sheep recorded the highest mean (0.91 kg , 101.63 kg , 104.86 day) compared to the Arabi sheep she was means (0.77 kg , 88.15 kg , 99.15 day) respectively. As well as in proportions of milk components with mean( 5.1 , 4.90 , 5.51) % respectively compared to the Arabi sheep (4.70 . 4.20 . 4.89) ewes with male lambs also exceeded superior ewes with female lambs in daily and total milk production and the lactation period the sex of the lamb did not affect the proportions of milk components the weight of the ewes had a significant effect (P <0.05) in milk production attributes with superior weight of ewes on lower ewes and did not affect the proportions of milk ingredients except for lactose. The type of birth and the age of the ewes did not have a significant effect in all the studied traits except for the superiority (P<0.05) of young ewes on age ewes in the fat percentage of milk.

The data on feeding dairy cows of an energy protein concentrate (EPC) are presented. EPC consists of grain of narrow-leaved lupine, flax, triticale, subjected to heat treatment on a press extruder. The effect of EPC on the change in milk production of cows was determined. The inclusion of extruded concentrate based on lupine grains in the diets of cows made it possible to obtain an increase in milk. Concentrate based on lupine, flax, triticale is equal in biological value to full-fat soy, and at a much lower cost.

Many mothers who give birth to Sectio Caesarea (SC) do not Initiate Early Breastfeeding (IMD), which fails exclusive breastfeeding. This study aimed to determine the effect of IMD management in postpartum SC mothers on nutritional status, speed of milk production, and quality of breast milk protein. Method: quantitative research with quasi approach experiment. The research design used was a pre-post-test control non-equivalent control group. A sampling of this study used the Consecutive method sampling with a sample of 20 mothers who gave birth by cesarean section (SC). Hypothesis testing uses the independent t-test and the Mann-Whitney test. The study results showed an influence on the management of IMD in postpartum SC mothers on the speed of ASI production (p-value=0.004) and nutritional status (p-value=0.028). There was no effect of IMD management on postpartum SC mothers on the quality of breast milk protein (p-value = 0.543). This study recommends that the hospital implement an IMD promotion program before the abdominal wall is closed as a form of intervention to increase milk production and maternal nutritional status
