IN 1938 an investigation on the effects of different planes of nutrition of ewes upon the birth weight and growth of lambs was undertaken at the Animal Nutrition Institute of the School of Agriculture, Cambridge, by Dr Verges, with the result that two groups of ewes respectively of about 70 and 150 lb. live weight were obtained from the restricted and full diets given. Five of the 70 lb. animal...

The objective of the current study was to determine the effect of pre-slaughter stress, season and breed on the activity of plasma creatine kinase (CK) and the quality of mutton. One hundred and seventy-three (173) castrated sheep from Dormer (DM), South African Mutton Merino (SAMM), Dorper (DP) and Blackhead Persian (BP) sheep breeds were used in the study. The animals were grouped according t...

A TOTAL of 28 crossbred wethers were used in two experiments to determine the digestibilty of hydrogenated tallow-, saturated fatty acidsand soybean oil-supplemented diets. Digestibility values for individual fats were determined by subtracting from total dietary lipid and fecal output the dietary and fecal lipids measured with basal diets. In the first experiment addition of 3% flaked, hydroge...

The establishment of exotic invasive species, including plants, has been linked to the decline of some amphibian populations. Of particular concern with invasive plants, from an amphibian conservation perspective, is that they are disproportionately wetland or riparian species. Recent evidence suggests that Chinese tallow (Triadica sebifera), an exotic deciduous tree species, is expanding its r...

Five experiments were conducted to determine the effect of fat addition to dry-rolled corn (DRC) finishing diets on subacute acidosis. In Exp. 1, five ruminally fistulated steers (410 +/- 12 kg BW) were used in a 5 x 5 Latin square design. Treatments consisted of 0, 2, 4, 6, or 8% tallow added to a 50% fine-ground corn: 50% dry-rolled wheat basal challenge diet and dosed intraruminally as an ac...

A differential display was performed to analyze differential gene expression in the brain of mice in association with dietary high beef tallow. Consumption of a high beef tallow diet up-regulated the expression of zinc finger protein ZPR1 mRNA in the brain. Expression of ZPR1 mRNA in the cerebellum and hippocampus was elevated in response to the high beef tallow diet. The increased ZPR1 express...

The characteristic mutton odour, associated with the cooked meat of older sheep, can be problematic for some consumers who find the odour disagreeable. Branch chain fatty acids (BCFAs) are considered to be the main determinants of mutton odour. In this study, the aim was to identify the factors influencing the BCFA content of animals at abattoirs in Australia. Samples of subcutaneous fat from o...

We identify species–environment relationships to predict the occurrence of Chinese tallow (Triadica sebifera (L.) Small) on forestlands in the southern US, where it has emerged as the most pervading, stand-replacing, alien tree species. Tallow invasions are more likely to be observed on low and flat lands, areas adjacent to water and roadways, sites recently harvested or disturbed, younger stan...

Four trials were conducted with 1,480 pigs (initial wt: 23 kg in trial 1,29 kg in trial 2 and 49 kg in trial 3 and 4) to determine the effect of dietary fat on pig performance, nutrient separation in an automated feed distribution system, dust levels in swine buildings and integrity of the respiratory system of swine. Two modified-open-front (B-1 and B-2) and two environmentally regulated (E-1 ...

Effects of dietary fats consisting of different fatty acids on lipoprotein lipase activities in the interscapular brown adipose tissue, heart, and soleus muscle, and on body fat accumulation were studied in rats. Sprague-Dawley male rats were meal-fed an isoenergetic diet based on either beef tallow or safflower oil for 8 weeks. Lipoprotein lipase activities in the interscapular brown adipose t...
