  • A survey of the mineral status of livestock in the Tibet

    cattle, horses and sheep from different environment and management systems. This assessment involved the collection of blood, milk, urine and dung samples from animals and samples of grazed pasture and feed supplements for stone analyses.

  • Mineral program for cows on wheat pasture Drovers

    Oct 15, 2012· Many Oklahoma cow calf producers will use wheat pasture as a major source of winter feed for beef cows. If wheat pasture is the predominant feed in the diet of mature beef cows, providing an appropriate "wheat pasture" mineral mix will be helpful in preventing grass tetany at, or after the calving season begins.

  • Minerals for Beef Cows Penn State Extension

    The most important source of minerals for beef cows comes from the pasture and forages they are grazing since these feeds contribute the highest percentage of the diet. These feeds are, in fact, good sources of most of the required minerals. The values in Table 1 are the requirements (NRC, 1986) of most major minerals for beef cows.

  • A Case Study of Behaviour and Performance of Confined or

    1. Introduction. Sixty percent of dairy producers in the United States house dry cows separately from lactating cows [] with the majority of operations housing dry cows in tie-stalls or stanchions (18.2%), freestalls (29.3%), pasture (11.3%), or dry-lots (29.2%) [].Though a large number of dairy operations use tie-stalls and stanchions for dry cows, they are more common in smaller dairies

  • Animals Free Full-Text Welfare Assessment on Pasture

    Outdoor and extensive farming systems allow animals to behave in a natural way and are often perceived as welfare friendly. Nonetheless, the natural environment poses multiple challenges to the welfare of animals, sometimes hampering their capacity to cope. Welfare assessment in outdoor and extensive systems has been rarely investigated, and little is known about the most appropriate indicators.

  • Assessment of pasture and plasma minerals of cows: A case

    Specific mineral supplementation should be supplied containing copper and zinc, as both pasture and blood plasma samples exhibited their deficiency. The present investigation suggests the requirement and provision of an appropriate specificity tailored mineral mixture to ruminants in this specific studied area.

  • A recent assessment of the elemental composition of New

    The minerals required for good plant growth were found at adequate concentrations in the majority of pastures. The exception was P; only 74% of pastures contained the recommended 3.5 mg P/kg DM. Results of the pasture survey were compared to the dietary intake requirements of cattle and sheep.

  • Effect of selected factors on mineral parameters in plasma

    of cattle according to nutrient requirements. Minerals were remained available for ad libitum consumption at a single location in each pasture and outside yard in free-choice mineral feeders. All cows received the same respective mineral supplement. Ad libitum access to water was maintained throughout the study.

  • Identification of Suitable Animal Welfare Assessment

    Farm animal welfare assessment protocols use different measures depending on production systems and the purpose of the assessment. There is no standardized validated animal welfare protocol for the assessment of beef cattle farms in New Zealand, despite the importance of beef exports to the country. The aim of this study was therefore to identify welfare measures that would be suitable for an

  • Assessment of magnesium intake according to requirement in

    1 INTRODUCTION. Magnesium (Mg) is an essential mineral (Leroy, 1926) with numerous cellular functions (Romani & Scarpa, 2000).The cytosolic concentration of the free ionized Mg ion is ~1 mmol/L (McGuigan, Kay, Elder, & Lüthi, 2007).However, due to the presence of anions such as phosphate in nucleic acids (Günther, 1981) or ATP 4− binding Mg (Gabriel & Günzel, 2007), the total

  • Use of Anionic Salts with Grazing Prepartum Dairy Cows

    Cows calved on pasture and were then integrated into the regular milking herd and fed a total mixed ration (TMR). Daily milk yield and weekly milk samples were collected through wk 14 of lactation. Prepartum and postpartum DMI, milk yield and composition, and plasma minerals


    Dairy cows with plasma concentrations of á-tocopherol less than 3 mg/liter were 9.4 times more likely to have clinical mastitis than cows with concentrations greater than 3 mg/liter. This shows the importance of maintaining an appropriate vitamin E status in the animal in

  • Lab Tests to assess reliably the Mineral Status of Cattle

    BLOOD is the standard tissue used internationally for accurate routine assessment of the mineral status of cattle & sheep. For milk to replace blood as the standard sample for this purpose, levels of the relevant minerals in blood & milk should correlate very highly; unfortunately, in most cases, the correlation for a given mineral are very poor.

  • Fast Assessment of Mineral Constituents in Grass by

    Brazil has the biggest cattle herd in the world, with more than 95% of the animals being grown in pastures. Certainly, the milk and meet quality will depend on the grass composition, which should be known (Martuscelo et al. 2009; Souza et al. 2007). For an adequate animal feed, inorganic nutrients or mineral compounds are required.

  • Experimental assessment of stone mineral density using

    Apr 14, 2016· The aim of this study was to assess the measurement of stone mineral density (BMD) by quantitative computed tomography (QCT), comparing the relationships of BMD between QCT and dual-energy X-ray absorptiometry (DXA) and between QCT and radiographic absorptiometry (RA) in the metacarpal stone of Holstein dairy cows (n=27).

    “Cows were scored as 1= calm, no movement to 5= violent and continuous struggling while in the working chute. Also, a pen score assessment was assigned as 1= unalarmed and unexcited to 5 = very excited and aggressive toward the technician. An exit velocity speed score was measured as the cows exited the working chute as 1= slowest and 5

  • Farm Health Online Animal Health and Welfare Knowledge

    The occurrence of lactation or grass tetany can occur in three sets of circumstances. Most common is the occurrence in lactating dairy cows after turnout onto lush, grass-dominant pasture following winter housing. Most cases occur during the first 2 weeks after the animals leave the housing.

  • Farm Health Online Animal Health and Welfare Knowledge

    In cows fed stored forages, relatively high supplemental levels of vitamin E (3000–4000 IU/day) are needed to prevent the drop in plasma-tocopherol concentrations around parturition. However, for cows with existing adequate intakes, increasing vitamin E intake above the current recommended levels is not associated with a reduction in disease

    The cows were enlisted in the study after their admittance at the clinic over a period of 7 months. The lactation status of the cows differed substantially between 6 and 234 days in milk (median 56 days), similarly milk yield also varied widely between 0 and 24 L/d (median 9.4 L/d). Body weight at admission varied between 670 and 810 kg.
