Whole Grain Cereal

The suitability of feeding whole grain cereal (maize or sorghum) in diets was investigated in three individual-feeding trials conducted under simulated tropical conditions. In each trial rabbits were allocated to one of four diets (Table 1); complete pelleted diet based on maize (PM), whole maize plus pelleted concentrate supplement (WM), complete pelleted diet based on sorghum (PS) or whole sorghum plus pelleted concentrate supplement (WS). In Trial 1 whole maise and whole sorghum contained 84 and 103 g crude protein/kg dry matter (DM) respectively. In Trials 3 and 3 whole maize and whole sorghum contained 60 and 98 g crude protein/kg DM and 18.87 and 18.67 MJ gross energy/kg DM respectively.

Data from 33 feeding trials, conducted on lactating riverine buffaloes from different institutes across India, were subjected to multiple regression analysis to derive nutritional requirements for dry matter (DM), total digestible nutrients (TDN), crude protein (CP) and digestible crude protein (DCP) for maintenance, milk production and body weight gain. Maintenance requirements for DM, TDN, CP and DCP were 59.9, 35.3, 5.43 and 3.14 g/kgW0.75, respectively; corresponding requirements for producing 1 kg 6% FCM were 688, 406, 90.3 and 55.2 g and for 1 g gain in body weight were 3.37, 1.97, 0.327 and 0.23 g. Regression equations had high R2 values (0.61, 0.66, 0.84 and 0.68 for prediction of DM, TDN, CP and DCP, respectively) and the equations (F-value) as well as coefficients were highly significant (P<0.001). Regressed values were used to derive feeding standards. Derived values matched well with the actual intake versus performance of animals under diverse feeding conditions. New standards predicted requirements and intake of nutrients for different production levels better than existing feeding standards. Because they are based on a more thorough analysis of data, the new feeding standards will be appropriate for use widely in India.

This study investigated the effects of sorghum ensiled as whole grains with different dry matter concentrations on the apparent total tract digestibility (ATTD) of energy, crude nutrients and minerals in growing pigs. Whole grain sorghum batches with varying dry matter (DM) concentrations of 701 (S1), 738 (S2) and 809 g kg−1 (S3) due to different dates of harvest from the same arable plot, were stored in air-tight kegs (6 L) for 6 months to ensure complete fermentation. Subsequently, 9 crossbred barrows (34.6 ± 1.8 kg; (Duroc x Landrace) × Piétrain)) were used in a 3 × 3 Latin square feeding experiment. Diets were based on the respective sorghum grain silage and were supplemented with additional amino acids, minerals and vitamins to meet or exceed published feeding recommendations for growing pigs. The ATTD of gross energy, dry matter, organic matter, nitrogen-free extracts, and crude ash were higher in S1 compared to S3 treatments (p ≤ 0.05), while S2 was intermediate. Pigs fed S1 showed significantly higher ATTD of phosphorus (P) compared to all other groups while ATTD of calcium was unaffected irrespective of the feeding regime. In conclusion, growing pigs used whole grain sorghum fermented with a DM concentration of 701 g kg−1 (S1) most efficiently. In particular, the addition of inorganic P could have been reduced by 0.39 g kg−1 DM when using this silage compared to the variant with the highest DM value (809 g kg−1).

Abstract This study was conducted to determine the effect of pelleting on the digestibility of corn-soybean meal-based diet in growing pigs. Two trials with 6 pigs cannulated at the distal ileum were conducted. In each trial, pigs were assigned to each treatment following a crossover design. In each experiment, the same diet, composed of corn and soybean meal with 10% wheat from two different feed mills, was served in pellet or mash form. Pelleting allowed an increase in digestibility in one of the trials. Apparent ileal digestibility (AID) of dry matter (DM), crude protein (CP) and digestible energy (DE) were improved with pelleting by 8, 12 and 9% (P&lt; 0.01). The AID of amino acids (AA) was also improved (P&lt; 0.05). Apparent total tract digestibility (ATTD) was increased by pelleting in DM, CP and DE by 5, 7 and 6% respectively (P&lt; 0.01). The digestibility of the mash diet in experiment 1 was lower than in the pelleted diet in the experiment 1 and both diets in experiment 2 as shown by the interaction Pelleting X Trial which was significant for the AID and ATTD of DM, CP and DE (P&lt; 0.01). Therefore, in experiment 1, pelleting allows to improve the digestibility of diet to the same level as in experiment 2. The AID of CP was higher by 37% in the mash diet from the second experiment compared to the one in the first experiment. Even though the same ingredients were chosen in the two experiments, this shows the variability in digestibility existing between different feed mills and ingredient sources. This difference was not observed in pelleted diets. The results obtained in these two trials show that pelleting can reduce the variability of digestibility and then give a good digestibility of diets even if the ingredients are of different quality or sources.

SUMMARY1. A split-plot design was used to study apparent digestibility of dry matter, gross energy and nitrogen of a whole grain wheat diet and processed (hammermilled, rolled or hammermilled and then steam-pelleted) wheat diets by eight small (33·9 ± 0·1 kg) and eight large (70±1·7 kg) pigs. Metabolizable energy and nitrogen retention were also studied with the small pigs.2. The processed wheat diets were superior to the whole grain wheat diet in all the parameters measured.3. There were no significant differences between the performance of pigs given the differently processed wheat diets.4. Apparent digestibility of dietary components particularly in the whole wheat diet was significantly higher when diets were given to small pigs than when given to large pigs.

Feeding trials involving a total of 78 Holstein steers and utilizing barley diets were conducted to determine the effects of vitamin E and trace minerals, hay, diethylstilbestrol, and physical form of the barley on rate of gain, feed efficiency and carcass characteristics.In the first trial, a basal diet containing 13.2% crude protein was used. Inclusion of a vitamin E, manganese, zinc, copper and sulfur supplement, 10% hay, or urea in the pelleted diets, or implantation with 9 mg of diethylstilbestrol at the initial weight of 92 kg did not improve rate of gain or dressing percent (P < 0.05). The inclusion of 10% hay reduced feed efficiency (P < 0.05).In the second trial in which dry-rolled, steam-rolled, dry-rolled and pelleted, and steam-rolled and pelleted barley diets were fed, the dry-rolled diet gave slower gains than the diets containing steam-rolled barley or steam-rolled, pelleted barley (P < 0.05). Implanting steers fed the steam-rolled, pelleted diet with 24 mg of diethylstilbestrol at 240 kg liveweight increased rate of gain over other treatments (P < 0.05). Treatments did not affect feed efficiency. Dressing percent was increased in steers fed steam-rolled barley in comparison with those fed dry-rolled barley.

Abstract An experiment was conducted to test the hypothesis that Cu hydroxychloride improves nutrient digestibility and alters the concentration of microbial protein in the small intestine or large intestine by pigs fed a corn-soybean meal diet or a diet based on corn, soybean meal, and distillers dried grains with solubles (DDGS). Twenty-four barrows (33.3 ± 3.4 kg) that had a T-cannula installed in the distal ileum were allotted to a 2 × 2 factorial design with 2 levels of DDGS (0% or 45%) and 2 levels of supplemental Cu from Cu hydroxychloride (0 or 150 mg/kg). A 2-period switch back design with the 4 diets and 6 replicate pigs per diet in each period was used resulting in 12 replicate pigs per diet for the 2 periods. The initial 9 d of each period was considered an adaptation period to the experimental diets. For each period, feces were collected on days 10, 11, and 12, and ileal digesta were collected for 8 h on days 13 and 14. Results indicated that inclusion of 45% DDGS to diets reduced (P &lt; 0.05) the apparent ileal digestibility (AID) of AA and the AID and the apparent total tract digestibility (ATTD) of dry matter, gross energy, and crude protein. In contrast, inclusion of DDGS to diets increased (P &lt; 0.05) the AID and the ATTD of acid hydrolyzed ether extract and the concentration of microbial protein in the hindgut (P &lt; 0.05). However, the total concentration of volatile fatty acids (VFA) in ileal digesta and in feces from pigs fed the DDGS diets were not different from concentrations in pigs fed diets without DDGS. The AID and ATTD of dry matter, gross energy, and crude protein were not affected by dietary Cu concentrations, but the AID and ATTD of acid hydrolyzed ether extract were greater (P &lt; 0.05) in diets supplemented with Cu hydroxychloride compared with diets without Cu hydroxychloride. There was also a reduction (P &lt; 0.05) in the concentration of microbial protein and a tendency for a reduction (P &lt; 0.10) in the total concentration of VFA in feces when diets were supplemented with Cu hydroxychloride. In conclusion, supplementation of Cu hydroxychloride to diets improved AID and ATTD of acid hydrolyzed ether extract and reduced the concentration of microbial protein in the large intestine and this effect was observed in diets containing DDGS as well as in diets without DDGS.

Feeding Trials

In pen feeding trials with eight Merino wethers, digestion coefficients were estimated for rations of cereal chaff-wheat grain-oat grain mixture, and wheat grain and oat grain fed separately at two levels of intake. Digestion coefficients for wheat and oat grain fed at 675 g/day in a double crossover experiment were dry matter 89.4, 80.8 per cent, organic matter 90.1, 82.6 per cent, protein 82.3, 77.6 per cent, ether extract 84.1, 90.9 per cent, crude fibre 33.2, 59.9 per cent, nitrogen free extractives 93.2, 85.8 per cent, energy 88.1, 81.0 per cent, total digestible nutrients 91.6, 87.1 per cent, and starch equivalents 90.7, 85.7. When these grains were fed at 785 g/day there was about 10 per cent improvement in crude fibre digestibility for both grains and 1-2 per cent improvement for other estimations with oats but not with wheat. The gross energy content of the wheat and oat grains when fed at 675 g/day was 4407 and 4700 calories/g dry matter. The digestible energy of the wheat in calories/g dry matter and organic matter was 3869 � 30, 3933 � 30 and for oats 3791 � 59, 3910 � 61. When fed at 785 g/day these values for wheat were 3850 � 50,3911 � 51 and for oats 3796 � 34, 3913 � 51. A highly significant relationship was found between energy and dry matter digestibility which for wheat diets was Y = 1.074x 7.840. r = 0.993 (P<0.001), and for oats and the mixed diet of cereal chaff-oat grain-wheat grain, Y = 0.983x + 1.550. r = 0.996 (P<0.001) where Y = energy and X = dry matter digestibility and r = the coefficient of correlation. Because of the similar digestible energy content of, and the body weight gains of sheep on, these two grains it was concluded that under the present conditions these grains were equivalent weight for weight.

Basal Ration

Kids six months old and of mean liveweight 22 kg were offered a basal ration of barley and lupins (crude protein 15 .4%) supplemented with three levels of chopped hay (0, 13% of total intake and ad libitum). Supplementation of the basal ration with 13% hay increased total dry matter intake from 479 to 753 g/d (P< 0.001) and liveweight gain from 10 to 54 g/d (P<0 .01). Non-significant increases in total food intake and liveweight gains were achieved by supplementing with ad libitum hay; kids fed ad libitum hay actually consumed 26.9% of their diet as hay. They were then offered various mixtures of barley, oats and lupins with 13% chopped hay at near ad libitum feeding. Differences in intake or growth were not significant at P= 0.05 with kids growing at 74, 65 and 101 g/d for those fed barley, oats and lupins respectively. Results indicate that highest food intake was obtained when 13% chopped hay was added to whole barley grain rations.

Feeding Trials

SUMMARYReindeer calves(Rangifer tarandus tarandus) were used in parallel feeding trials with two different qualities of round-bale timothy silage in September 1992 (summer) and April 1993 (winter) in northern Norway, to determine the effect of season on their food intake and ability to utilize silage of different fibre contents. The silages were prepared from first-cut (FC) and regrowth (RG) timothy. The FC silage contained (on a dry matter (DM) basis) 12·3% crude protein, 30·4% cellulose and 6·2% water soluble carbohydrates (WSC), whereas the RG silage contained 14·3% crude protein, 18·7% cellulose and 30·0% WSC. For each trial, six male calves were taken directly from a natural range and divided into two groups of three animals. One group was offered FC silage and one RG silagead libitum, for 46 days. Mean daily DM food intake (g/kg liveweight) was not significantly different in summer compared to winter(P> 0·05), but significantly higher in the animals fed RG silage compared to the animals fed FC silage (P< 0·0001). The apparent digestibility coefficient of DM was high for both silages both in summer and winter, ranging from 74·4 to 86·6%. However, the digestibility in winter was significantly higher than in summer(P< 0·002) and the digestibility of RG silage was higher than that of the FC silage (P< 0·009). The ruminal VFA concentration was significantly higher in winter than in summer (P< 0·03) and in the animals fed RG silage (range 55·3–104·9 mM) compared to the animals fed FC silage (range 35·2–61·7 mM) (P< 0·002). In spite of the high digestibility of both the FC and RG silages, the nitrogen balance was significantly higher in the animals in winter compared to summer(P< 0·0001) and in the animals fed RG silage compared to the animals fed FC silage(P< 0·0001). Thus, utilization of grass silage in reindeer appears to be influenced both by season and by plant quality.
