Three Stages

The choice of optimal stage of maturity at harvest for whole-crop wheat remains controversial. Problems of aerobic stability with crops harvested and ensiled at an early stage led to increased interest in harvesting at a later stage and preserving the crop with urea. However recent studies have shown low starch and fibre digestibility with such crops when fed to lactating dairy cows (Sutton et al.,1991). The purpose of the present work was to determine the effect of harvesting wheat at three stages of maturity on the in situ degradability of dry matter (DM), neutral detergent fibre (NDF) and starch.

Different Levels

A study of six months duration was conducted to assess the effect of paddy straw based complete rations containing different levels of NDF on digestibility coefficients of nutrients in lactating dairy cows, in two phases, viz., early and mid lactation. Three isonitrogenous and isocaloric complete rations, T1, T2 and T3 with 25, 30 and 35 per cent NDF, respectively were formulated as per ICAR (1998). Paddy straw was the sole source of roughage NDF, with the rest of NDF being met from non-forage sources, in all the three rations. Eighteen dairy cows yielding approximately 10 kg of milk per day were divided into three groups of six each, and allotted to the three experimental rations. There was no significant difference (P>0.05) in digestibility coefficients of nutrients such as dry matter, organic matter, crude protein, crude fibre, ether extract, nitrogen free extract, NDF and energy, among the dietary treatments, in both phases I and II. However, the digestibility coefficient of acid detergent fibre was significantly higher (P less than 0.05) in T2 and T3 than T1, with T2 and T3 being similar (P>0.05), in both the phases. A thorough evaluation of the results obtained in the present study, reveal that the animals in all the three dietary treatments performed well, with the complete rations T3 with 35 per cent NDF and T2 with 30 per cent NDF showing better performance than T1 with 25 per cent NDF. Between T2 and T3 which were more or less comparable, the cows fed on the diet T3 had a higher digestibility for NDF, ADF and crude fibre, indicating that T3 was better than T2. These results suggest that complete rations with 25 to 35 per cent NDF, containing paddy straw as the sole source of roughage NDF, with the rest of NDF being met from non-forage sources, can be recommended for use among early and mid lactation dairy cows, with 35 per cent being the ideal NDF level.

Daily Milk

Context In Brazil, dairy cattle pasture-based systems use grass pasture as the main feed source, with little or no supplementation. However, it is necessary to invest in nutritional technologies that allow dairy cattle systems to produce milk with a high protein and energy content, and better total bacterial counts at low costs. Aims This study aimed to evaluate the effect of adding a common bean residue (CBR) to cattle diets on feed intake, digestibility and feeding behaviour of lactating dairy cows. Methods Eight lactating Holstein × Zebu crossbred cows, with an average bodyweight of 500 ± 30 kg (mean ± s.d.) and a mean daily milk yield of 13 ± 2 kg/cow were randomly assigned in a double 4 × 4 Latin square. The treatments consisted of four increasing levels of CBR (134, 240, 348 and 449 g/kg) in the concentrate. Key results The inclusion of CBR linearly decreased (P ≤ 0.034) the DM intake and neutral detergent fibre intake of pasture, sugarcane and the total diet. The inclusion of CBR did not affect (P ≥ 0.111) grazing, rumination or idle time. The feeding efficiency in kg DM/h and kg neutral detergent fibre corrected for ash and protein/h linearly decreased (P < 0.001), with an estimated decrease of 39.1 and 23.4 g/h respectively for every 10 g/kg of CBR added to the concentrate. The number of boluses per day and the time spent per ruminated bolus were not affected (P ≥ 0.086) by CBR inclusion. Conclusions The results obtained in this study indicate that the inclusion of up to 240 g/kg of CBR to the diets of lactating dairy cows with a mean daily milk yield of 13 kg, managed on pastures, is recommended. Implications The use of CBR, which has high availability in several countries, may be an alternative to supplying small ruminants.
