Supplementing Dairy Cows In Late Lactation With High Quality Silages, Todd A. White, Trevor L. Knight, M. G. Hyslop, Tom J. Fraser
IGC Proceedings (1997-2023)
Agriculture on the Canterbury Plains of New Zealand is a mixture of integrated cropping and pastoral enterprises. Cropping farmers often provide supplementary feed for dairy farmers by growing forages for high quality silage. Such silages can improve milk production by increasing dry matter (DM) intake and/or by alleviating deficiencies of either soluble carbohydrate or protein in pasture (Woodward et al., 2002). Legumes and/or cereals have potential to make large quantities of high quality silage (de Ruiter et al., 2002). This trial aimed to determine milk production and composition differences between three silages fed during late lactation.

Whole Crop Cereal Silage In Dairy Production, J. Wallsten, L. Ericson, K. Martinsson
IGC Proceedings (1997-2023)
Whole-crop cereal silages (WCCS) are used to some extent in Sweden, but knowledge about the use of this feed for high yielding dairy cows is scarce. The crop is often harvested at different stages of maturity, from heading to yellow ripeness, which gives forages that differ in chemical composition. The purpose of this trial was to compare intake and milk production of dairy cows fed a WCCS based on barley harvested at three different stages of maturity.

Effect Of Potato Pulp Silage Supplementation On Milk Production In Cows Grazing Temperate Pasture, Masaaki Hanada, Y. Aibibula, D. Okumura, Meiji Okamoto
IGC Proceedings (1997-2023)
In a dairy farming system based on pasture in Japan, maize grain is generally used as an energy source for milking cows, with almost all grain been imported. Potato-pulp is one of the agricultural by-products derived from the starch industry in the northern island of Japan. In our previous study (Aibibula et al., 2004), it was demonstrated that potato pulp could be preserved for a long time by ensiling without additives, and that the digestible energy value of potato pulp silage (13 MJ/kg DM) was almost the same as beet pulp. From these results, it is possible that some …

IGC Proceedings (1997-2023)
Supplementation is a very efficient approach for improving animal performance and gain/ha in grazing systems in tropical conditions. However, care needs to be taken to avoid substitution effects (Moore et al., 1999). Results may also depend on animal genetics and the availability and nutritional value of forage. This trial aimed to evaluate different levels of supplementation using steers from different genetic groups on palisade grass (Brachiaria brizantha cv. Marandú) pasture during the rainy season.

Suitability Of Selenate Containing Silage Additives For The Supply Of Beef Cattle, Harald Laser
IGC Proceedings (1997-2023)
Selenium concentrations in herbage are frequently insufficient (< 100 μg Se/kg dry matter (DM)) to meet the requirements of ruminants. Whereas increasing Se supply by feeding mineral mixtures is a reliable method to prevent Se deficiencies for dairy cows, adequate Se supplementation is more difficult to achieve in extensive systems (McDowell, 1996). A suitable measure could be the addition of Se to herbage before ensiling.

Effect Of Supplementation On Performance And Faecal Particle Size Distribution For Yearling Horses And Weaned Calves Grazing Coastal Bermudagrass, F. M. Rouquette Jr., K. N. Grigsby, D. K. Hansen, G. D. Potter, W. C. Ellis
IGC Proceedings (1997-2023)
Supplements are often fed, especially to horses, without realistic expectations of the magnitude of performance response nor knowledge of biological or economic efficiencies of supplementation. The objectives of this experiment were to compare performance of weaned calves vs yearling horses grazing 'Coastal' bermudagrass [Cynodon dactylon (L.) Pers] (COS) pastures with and without a protein-energy supplement, and to assess faecal particle size distribution for both calves and horses to document digesta dynamics.

West African Dwarf Goat Response To Supplementary Feeding In Cameroon, E. Tedonkeng Pamo, B. Boukila, F. Tendonkeng, J. R. Kana
IGC Proceedings (1997-2023)
The production of the West African Dwarf goat (WADG) in Cameroon is very low, because of lack of proper nutrition. Nitrogen content is generally very low and fibre content is high, both in the grass and the crop residues which form the basis of their diet particularly during the dry season. Supplementation of these roughages is a promising way of alleviating nutrient deficiencies. Different types of supplementary feeding have been advocated to boost goat production (Leng, 2003), of which supplementary feeding with leguminous tree leaves is of high merit. The present study was undertaken to evaluate the effects of supplementary …

New Advance In Forage Production And Dairy Industry In China, Zhiqiang Q. Li, J. G. Han
IGC Proceedings (1997-2023)
There were 6.9 million dairy cows in China in 2002 with milk yield of 13 million t. These values were 21.4 and 26.7% higher respectively than in 2001. Milk yield per cow was 1891 kg, 4.4 % higher than in the previous year, but still one third lower than the world average. Milk fat and protein contents were about 3.2 and 3.0 % respectively, a little below the world average. Milk consumption was 10.9 kg per person, much lower than the world average (97.6 kg) So, although great changes have taken place in dairy breeding, forage production and disease control, …

Productivity Of Sahiwal And Friesian-Sahiwal Crossbreds In Marginal Grasslands Of Kenya, W. B. Muhuyi, F. B. Lukibisi, S. N. Ole Sinkeet
IGC Proceedings (1997-2023)
Dual-purpose cattle can be used to exploit the production potential of semi-arid grasslands of Kenya for milk and meat production. Although the Sahiwal is adapted to these grasslands, its productivity is low. In order to increase milk and meat productivity, the Sahiwal has been crossed with the Friesian to produce Friesian-Sahiwal crossbreds (McDowell et al., 1996) adapted to the tropical environment. The objective of this study was to evaluate the productivity of Sahiwal and Friesian-Sahiwal crossbreds.

The Effects Of A High Grass Input Feeding System Compared To High Concentrate Input Feeding System Offered To Spring Calving Dairy Cows In Early Lactation, E. Kennedy, M. O'Donovan, J. P. Murphy, F. P. O'Mara, L. Delaby
IGC Proceedings (1997-2023)
Grazed grass is the cheapest feed available on Irish dairy farms. The inclusion of grass in the diet of the spring-calving dairy cow in early lactation is recommended. Previous studies focused on introducing grazed herbage into the cows diet in early spring in conjunction with grass silage and concentrate, and compared this to cows fed indoors. The objective of this study was to compare the milk production and feed budget of two contrasting early lactation feeding regimes. One regime was based on a high herbage inclusion with a low concentrate level (HG), while the other was based on a high …
A Comparison Of A Full Time Grazing And A Partial Storage Feeding System, For Dairy Cows,

A Comparison Of A Full Time Grazing And A Partial Storage Feeding System, For Dairy Cows, C. P. Ferris, D. C. Patterson
IGC Proceedings (1997-2023)
Partial storage feeding has been adopted by a number of Northern Ireland dairy farmers in recent years. This is due in part to increasing cow numbers, and as such, insufficient pasture close to the milking parlour to permit full time grazing. Partial storage feeding may also have environmental benefits, as well as reducing labour requirements associated with 'droving' and pasture management. In view of this, a study was undertaken to examine animal performance with either a full-time grazing, or a partial storage feeding regime.

Effect Of A Summer Period At Pasture On The Performance Of Young Bulls Offered Concentrates Ad Libitum, R. J. Fallon, M. G. Keane
IGC Proceedings (1997-2023)
Holstein bull calves can produce a 250 kg carcass at 11 to 12 months of age on indoor feeding of ad libitum concentrates. An outdoor period at pasture would reduce housing costs. Two experiments were undertaken to determine the effect of an outdoor period at pasture on concentrate intake, liveweight gain and selected carcass traits of Holstein young bulls.

IGC Proceedings (1997-2023)
Suckler beef systems in Ireland are primarily based on grass. Suckler systems vary in intensity but many operate low input systems and participate in REPS (Rural Environmental Protection Scheme). As there is a considerable cost associated with second-cut silage this research compared a two-cut system with a simplified low input one-cut system.

Effect Of Time Spent On Pasture On Milk Production And Quality In Latxa Dairy Sheep, A. Garcia-Rodriguez, N. Mandaluniz, L. M. Oregui
IGC Proceedings (1997-2023)
Dairy sheep production systems in the Basque country are pasture based. Forage resources are managed by shepherds who match herbage, forage and supplement availability with production requirements. This is achieved through a part-time grazing system, where ewes spend 3 to 7 hours grazing. The aim of this study was to evaluate the effect of restricted access to pasture on milk production and quality.

Animal unit equivalents (AUEs), provide a means of summarising grazing capacity, calculating stocking rates and other stocking variables (Scarnecchia, 1990). Animal units (AU) are often defined in relation to the dominant animal type in an area In Iran there are 27 sheep breeds which are classified into three main body size classes, namely: small, medium and large. The objective of this experiment was to define animal units, animal and forage requirements for sheep grazing in Mozandaran grasslands.

IGC Proceedings (1997-2023)
The use of P fertilisers together with legume broadcasting is a low cost and high impact technology for improving native grassland (Risso et al., 2001). Its use is increasing in Uruguay, although not for mixed grazing, even though this management is a common practice on native grasslands. Good pasture response may occur under mixed grazing when it is adequately managed (Nolan & Connolly, 1989). The following trials characterise pasture response with such management, in Uruguayan conditions.

IGC Proceedings (1997-2023)
In cow-calf operations in Uruguay, mixed cattle and sheep grazing on rangelands is predominant, while fattening is a specialised process. Within certain limits of the lamb/steer ratio and stocking rate, a complementary grazing effect occurs under mixed grazing, improving net results (Nolan & Connolly, 1977; Risso et al., 2002). These trials characterise animal performance under such management.

Constraints On Dairy Cattle Production From Locally Available Forages In Bangladesh, M. A. S. Khan
IGC Proceedings (1997-2023)
The productivity of milk producing animals in Bangladesh is low because of low individual yield and poor fertility. The reasons for the low productivity are complex but, in order of priority, appear to be (a) the imbalanced nature of the nutrients that arise from the digestion of the forage resources, (b) the incidence of disease/parasitism, and (c) the often harsh climatic circumstances. Thus, the purpose of this study was to find out the practical constraints on dairy cattle production from locally available forages under small holding village conditions of Bangladesh.
