A co-operative nutrition project involving eight institutions across Canada was undertaken in order to test some of the swine feeding standards in the 1953 revision of "Nutrient Requirements for Swine". Four stations (University of British Columbia, University of Alberta, University of Manitoba, and the Experimental Farm, Nappan, N.S.) conducted swine feeding trials. Four rations were fed at each station: A—a centrally formulated barley ration based on the N.R.C. requirements for protein, Ca, P, vitamins A and D; B—a formula chosen by the co-operator; C—a ration based on the standards but employing barley plus oats as the basal grains, all ingredients being from local supplies; D—similar to ration C, but with barley plus wheat as the basal grains.All feeds were analysed for crude protein, crude fibre, ether extract, ash, energy, Ca, P, weight/quart, riboflavin, niacin, choline and pantothenic acid. Carcasses were graded according to commercial grades and scored in detail according to Canadian Advanced Registry standards.Approximately normal gains and feed efficiencies were obtained during the growing period (40–110 lb.) despite riboflavin, T.D.N. and pantothenic acid levels below the standards. Similar results occurred in the finishing period (110–200 lb.) but carcass quality proved to be unsatisfactory. It is suggested that the gains during the finishing period represented too much fattening in relation to skeletal and muscle development.

Breeding Groups

Sixty-four castrate male pigs from four breeding groups were individually fed from 50 pounds to market weight of 195 pounds. From 50 to 110 pounds, comparison was made between linear programmed, least cost rations meeting minimum nutrient requirements and those with a 15 per cent margin of safety for protein, lysine, methionine, calcium, phosphorus, riboflavin, pantothenic acid, vitamins B12, A and D. From 110 to 195 pounds, each group was subdivided to compare rations meeting minimum nutrient requirements with those containing 16 per cent protein and corresponding increases in lysine and methionine.Feed intake was not influenced by ration or breeding. Rate of gain, nitrogen digestibility, and efficiency of feed and digestible energy utilization were improved by the margin of safety in nutrients during the growing period and by the higher protein level in the finishing period. Pigs previously receiving the ration with a margin of safety gained more slowly on the 16 per cent protein finisher than those previously receiving the minimum standard ration. Carcass measurements were not significantly changed by ration although area of longissimus dorsi muscle and total R.O.P. score tended to be increased for pigs finished on the 16 per cent protein ration. Breeding groups varied in rate of gain, energy digestibility, efficiency of feed utilization and carcass measurements. For rate of gain during the growing period there was an interaction between ration and breeding group.

Glenn M. Samm is at the University of British Columbia reported (Angew. Chem. Int. Ed. 2012, 51, 10804) the photofluorodecarboxylation of aryloxyacids such as 1 using Selectfluor 2. Jean-François Paquin at the Université Laval found (Org. Lett. 2012, 14, 5428) that the halogenation of alcohols (e.g., 4 to 5) could be achieved with [Et2NSF2]BF4 (XtalFluor-E) in the presence of the appropriate tetraethylammonium halide. A method for the reductive bromination of carboxylic acid 6 to bromide 7 was developed (Org. Lett. 2012, 14, 4842) by Norio Sakai at the Tokyo University of Science. Professor Sakai also reported (Org. Lett. 2012, 14, 4366) a related method for the reductive coupling of acid 8 with octanethiol to produce thioether 9. The esterification of primary alcohols in water-containing solvent was achieved (Org. Lett. 2012, 14, 4910) by Michio Kurosu at the University of Tennessee Health Science Center using the reagent 11, such as in the conversion of alcohol 10 to produce 12 in high yield. Hosahudya N. Gopi discovered (Chem. Commun. 2012, 48, 7085) that the conversion of thioacid 13 to amide 14 was rapidly promoted by CuSO4. A ruthenium-catalyzed dehydrative amidation procedure using azides and alcohols, such as the reaction of 15 with phenylethanol to produce 16, was reported (Org. Lett. 2012, 14, 6028) by Soon Hyeok Hong at Seoul National University. An alternative oxidative amidation was developed (Tetrahedron Lett. 2012, 53, 6479) by Chengjian Zhu at Nanjing University and the Shanghai Institute of Organic Chemistry who utilized catalytic tetrabutylammonium iodide and disubstituted formamides to convert alcohols such as 17 to amides 18. A redox catalysis strategy was developed (Angew. Chem. Int. Ed. 2012, 51, 12036) by Brandon L. Ashfeld at Notre Dame for the triphenylphosphine-catalyzed Staudinger ligation of carboxylic acid 19 to furnish amide 20. For direct catalytic amidation of carboxylic acids and amines such as in the conversion of 21 to 23, Dennis G. Hall at the University of Alberta reported (J. Org. Chem. 2012, 77, 8386) that the boronic acid 22 was a highly effective catalyst that operated at room temperature.

Shaorong Yang and Huanfeng Jiang of the South China University of Technology assembled (Angew. Chem. Int. Ed. 2014, 53, 7219) the β-lactone 3 by the Pd-catalyzed addition of 2 to the alkyne 1. Jack R. Norton of Columbia University observed (J. Am. Chem. Soc. 2015, 137, 1036) that the vanadium-mediated reduc­tive cyclization of 4 proceeded by a free radical mechanism, leading to the cis 3,4-disubstituted tetrahydrofuran 5. The cyclization of 6 to 7 developed (J. Org. Chem. 2015, 80, 965) by Glenn M. Sammis of the University of British Columbia also involved H atom transfer. Amy R. Howell of the University of Connecticut devised (J. Org. Chem. 2015, 80, 5196) the ring expansion of the β-lactone 8 to the tet­rahydrofuran 9. Dmitri V. Filippov and Jeroen D. C. Codée of Leiden University showed (J. Org. Chem. 2015, 80, 4553) that the net reductive alkylation of the lac­tone 10 led to 11 with high diastereocontrol. A. Stephen K. Hashmi of the Ruprecht-Karls-Universität Heidelberg optimized (Chem. Eur. J. 2015, 21, 427) the gold-mediated rearrangement of the ester 12 to the lactone 13. This reaction apparently proceeded by the coupling of the metalated lac­tone with a propargylic carbocationic species. Benjamin List of the Max-Planck-Institut für Kohlenforschung developed (Angew. Chem. Int. Ed. 2015, 54, 7703) an organocatalyst that mediated the addition of 15 to 14, leading to 16 in high ee. Scott E. Denmark of the University of Illinois published (Nature Chem. 2015, 6, 1056) a detailed study of the enantioselective cyclization of 17 to 18. Shunichi Hashimoto of Hokkaido University established (Tetrahedron Lett. 2015, 56, 1397) that his catalyst was effective for the cycli­zation of 19 to 20. Debendra K. Mohapatra of the Indian Institute of Chemical Technology showed (J. Org. Chem. 2015, 80, 1365) that allyl trimethylsilane could trap the intermediate from the cyclization of 21, leading to 22 with high diastereocontrol. Young-Ger Suh of Seoul National University used (Chem. Commun. 2015, 51, 9026) a Pd catalyst to cyclize 23 to (−)-deguelin 24. John Montgomery of the University of Michigan showed (Org. Lett. 2015, 17, 1493) that the Ni-catalyzed reduc­tive cyclization of 25 to 26 proceeded with high diastereoselectivity.

Ninety-two sows and two hundred and sixteen pigs were employed in four gestation-lactation and three growing-finishing experiments to determine the adequacy of barley grown on the Grey Wooded soils of the Peace River region in northwestern Canada, as a source of riboflavin, pantothenic and nicotinic acid in swine rations. Vitamin B12 was assessed as a dietary essential in the all-plant rations. In the gestation-lactation experiments sow gains during gestation were greater in the B-vitamin supplemented lot and a trend toward heavier weaning weights of pigs was evident. Vitamin supplementation increased the level of vitamin B12 in sow’s milk collected 1 week post-partum and of both riboflavin and pantothenic acid collected 1 week and 6 weeks post-partum. Nicotinic acid content of sows’ milk was unaffected by supplementation. There was a highly significant decrease in riboflavin level in both control and supplemented lots between 1 and 6 weeks following parturition. The decrease was greatest in the unsupplemented lot.B-vitamin supplementation did not affect growing period gains or pig carcass quality in the growing-finishing experiments. However, certain significant growth responses were noted in the finishing period.The data indicate that the basal rations employed contained adequate riboflavin, pantothenic and nicotinic acid to support normal gestation, lactation and growth in Yorkshire swine.

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.
