An experiment was conducted on HF x Kankrej crossbred calves to study the effect of formulated milk replacer on nutrients intake, feed conversion efficiency, cost of feeding and disease incidence. Eighteen newly born calves of either sex were selected. The calves were fed colostrum up to 3 days and from 4th to 9th day whole milk at the rate of 12.5% of body weight. From 10th day the calves were randomly distributed in to three treatment group. The calves of T1 group received whole milk as per routine farm practice; T2 group was fed whole milk and commercial milk replacer as per manufacturer’s recommendation, whereas T3 group calves received formulated milk replacer @ 12.5 % of body weight with upper limit of 4 kg per day. The overall initial (day 10) and final (day 94) body weight of calves were 27.71±6.53 and 44.96±10.60 kg, respectively. Overall average dry matter intake (DMI) per day, as per cent body weight and per kg metabolic body weight (W0.75) was 0.52±0.02 kg, 1.45±0.03 kg and 35.34±0.78 g, respectively. The dry matter intake in T1 was significantly higher followed by T2 than T3. Overall intake of total digestible nutrients (TDN) on daily, per cent body weight and per kg W0.75 basis was 0.546±0.02 kg, 1.28±0.04 kg and 31.03±0.87 g, respectively. The DM intake for each kg gain was significantly lower in T3 (3.07 kg) and T1 (3.02) than T2 (4.79 kg) calves. The feed conversion efficiency (TDN intake kg/kg gain) was significantly superior in T3 (2.22) followed by T2 (4.23), whereas in T1 (2.95) it was intermediate. The feed cost and total rearing cost were lower (p less than 0.05) for farm formulated milk replacer (T3) than commercial milk replacer (T2) and was highest for milk feeding (T1) group. The feed cost and total rearing cost per unit gain in weight were also lower (p less than 0.05) for farm formulated milk replacer (T3) than other two groups. The disease incidences were intermediate in farm formulated milk replacer (T3). Thus, raising crossbred calves on farm formulated milk replacer can be a better option for economic gain of farmers, health of calves and (sparing) more milk for humans.

The efficacy of sodium laurel sulfate as a defaunating agent, as well as effect of defaunation on body confirmation changes, wool yield and fibre characteristics, were evaluated in growing lambs in a 90-day feeding experiment. Forty-five Malpura male weaner (90-day old) lambs were divided into three equal groups: defaunated, refaunated and faunated. The lambs of defaunated and refaunated groups were defaunated by oral administration of sodium laurel sulfate at the rate of 8 g/100 kg liveweight as a 10% aqueous solution. Six days after defaunation, all the lambs of the refaunated group were refaunated by inoculation of 100 mL rumen content per lamb drawn from a normal faunated sheep. All the experimental lambs were maintained under stall feeding on a complete feed containing 50 : 50 Pala (Ziziphus nummularia) leaf and concentrate. Treatments did not differ in intake of dry matter, digestible crude protein or digestible energy. Body height and paunch girth were greater (P < 0.01) in defaunated compared to refaunated and faunated lambs. With similar dry matter intake in the three experimental groups, liveweight gain, feed conversion efficiency and wool yield were higher (P < 0.01) in defaunated lambs. The wool fibre diameter and medullation percentage were higher (P < 0.01) in defaunated than refaunated and faunated lambs. It was concluded from the study that, with similar dry matter intake and plane of nutrition, the growth rate, feed conversion efficiency and wool yield were higher in defaunated lambs, as compared to refaunated and faunated lambs. Higher paunch girth in defaunated lambs resulted in a pot-bellied appearance of the animals.

This experiment examined the association between the level of sorghum midge resistance of a grain sorghum hybrid and its ultilisation by cattle. Twenty-five Hereford steers were placed in individual pens and fed a feedlot ration (80% grain) for 8 weeks containing 1 of the following grain sorghum hybrids: Pacific 810, DK55plus (susceptible to midge); Barrier (low resistance to midge); AQL39/QL36, DK470 (moderate resistance to midge). There was no significant (P>0.05) difference between the hybrids in dry matter intake, liveweight gain, feed conversion efficiency, apparent nitrogen digestibility, and digestibility of the dry matter. No tannins were detected in the grain of any of the hydrids. It was concluded that the development of grain sorghum hybrids resistant to sorghum midge will not affect the utilisation of the grain in steers.

Feed Costs

This paper focuses on dairy herd performance in the United Kingdom and southern Australia, where feed costs have been estimated to comprise between 40 and 67% of the total costs of production. The efficiency of conversion of grazed pasture, home grown forages and purchased feeds into milk has a major bearing on farm profit. Feed conversion efficiency (FCE), defined as ‘kg milk of standardised composition with respect to protein and fat concentrations produced per kg feed dry matter consumed’, is a useful measure of the performance of a farm feeding system, but is seldom used by dairy farmers. It could also be defined as ‘g protein plus fat produced per kg feed dry matter consumed’, given that farmers are often paid for these components. The value of estimating FCE on an annual or shorter-term basis is discussed in relation to accepted principles of feed utilisation and dairy cow energy requirements. The implications of feed intake, conversion of ingested nutrients into absorbed nutrients and the subsequent utilisation of these nutrients for milk production or other purposes, as well as the effects of stage of lactation on FCE, are reviewed. Measuring FCE and identifying opportunities for improvement is relatively straightforward in housed feeding systems, but is more problematic under grazing. Hence, approaches and the key assumptions in estimating FCE in grazing situations, as well as possible limitations of these estimates, are discussed. Finally, a case study examining the potential impact of improved nutritional strategies on FCE and on margin over feed costs is presented. It is concluded that, to remain profitable, dairy farmers need to have a sound knowledge of cow nutrition, along with appropriate measures of FCE to monitor the performance of their milk production system. Such indicators of the biological performance of the farming system are most useful when used in conjunction with appropriate measures of economic performance.

A field study on early lactating crossbred cows (n=35) was conducted to evaluate the effect of feeding balanced rations on milk production, enteric methane emission, metabolites and feed conversion efficiency (FCE). In comparison to requirements, the dietary intake of protein and energy were higher by 25.0 and 12.7% whereas, calcium and phosphorus intake were lower by 30.0 and 27.0%, respectively. Balanced feeding improved daily 4% FCM yield by 0.7 kg/cow (P<0.05) and intestinal flow of microbial nitrogen (N) by 37.0% (P<0.01), whereas, reduced (P<0.01) feeding cost by 17.0% and enteric methane emission (g/d/cow and g/kg milk yield) by 14.6 and 18.1%, respectively. Level of IgG, IgA, IgM and uric acid content increased significantly, whereas BUN level reduced (P<0.01) from 18.2 to 15.0 mg/dl. FCE improved (P<0.01) from 0.8 to 1.0 and efficiency of microbial protein synthesis also improved (P<0.01) by 63.6% owing to feeding of balanced rations indicating better performance of cows. Present study indicates that feeding nutritionally balanced rations improved milk production, feed conversion efficiency and reduced methane emission in lactating cows under field conditions.

Effect Of Feeding

Twenty Yankasa rams, about 1.5 years and weighing between 20 and 25kg. were randomly alloted to four treatment groups of 5 animals each. The groups were used to study the effect of feeding concentrate and groundnut haulms in the ratio of 0:1 (A); 1:1 (B); 1:3 (C); 3:1 (D) on feedlot performance. All animals were fed at 4% of body weight in individual pens through the 86 day experimental period. Total dry matter intake was significantly (P<0.05) highest for Group D and lowest for Group A. It costs least to feed Group A animals but cost of feed per weight gain was least for Group D. Liveweight gain was highest for Group D, which utilized feed most efficiently.

The Mean

The production of biomass and antibacterial extracellular products by Lactobacillus casei subsp. casei CECT 4043 was followed in both batch and in realkalized fed-batch cultures. Enhanced concentrations of biomass and antibacterial extracellular products were obtained with the use of the latter fermentation technique in comparison with the batch mode. The culture obtained by fed-batch fermentation was mixed with skim milk and used to prepare a probiotic feed for weaned piglets. To test the effect of the potentially probiotic culture of L. casei on body weight gain, feed intake, feed conversion efficiency, and on fecal coliform counts of piglets, two groups of animals received either feed supplemented with the probiotic preparation or avilamycin for 28 days. The control group was fed nonsupplemented feed. At the end of the administration period (day 28), the groups receiving probiotic and avilamycin exhibited the highest average body weight gain values, although the mean feed intake and feed conversion efficiency values were not different among the groups (P &gt; 0.05). For the entire experimental period (42 days), the control group exhibited the lowest feed intake value, the probiotic group exhibited the highest feed conversion efficiency value, and the antibiotic group exhibited the highest body weight gain (P &lt; 0.05). Interestingly, no significant difference in body weight gain was observed between the probiotic and the control groups by day 42 (P &gt; 0.05). Fecal coliform values decreased (although not significantly) by day 28 in the three groups. However, the mean counts returned to pretreatment levels by day 42 in all groups.
