General Linear Model Procedure

This study was conducted to determine the relationship between plasma concentrations of thyroxine (T4), triiodothyronine (T3) and body weight in young Majaheem male camels. Eighteen camels aged 6 to 7 months were divided equally into three groups (Gl, G2 and G3). All groups were given concentrate pellets (187 g crude protein per kg) at the rate of 15 g/kg body weight daily. In addition, each group was given one of the following roughages: lucerne hay to Gl, rhodes grass hay to G2 and ammonia-treated wheat straw to G3. Roughages, salt and water were measured and given ad libitum. Every 2 weeks all camels were weighed and blood samples were collected. Data were statistically analysed using a general linear model procedure. There was a positive correlation between T4 concentration and body weight. T4 was higher in camels given either hay or straw compared with those given rhodes grass hay, while there were no differences among the three groups in T3 and in body weight.

1. Thirty Suffolk × Half bred lambs were slaughtered at the following ages: two twin lambs at birth and two singles and two twins at 1, 2, 3, 4, 6, 8 and 16 weeks of age.2. The following weights were recorded: live-weight immediately before slaughter; and carcass, head, skin, feet, alimentary tract, heart, liver, kidneys, lungs and trachea, and blood immediately afterwards.3. The alimentary tract was emptied and weighed in four separate parts; reticulo-rumen, omasum-abomasum, small intestine, large intestine.4. The volumes of the reticulo-rumen and the omasum-abomasum were measured by immersing in water and filling the organs with water to 2 cm. pressure.5. The in vitro digestive efficiency of rumen liquor from lambs of 1, 2, 3 and 4 weeks of age was assessed.6. Empty body weight was considered to be valuable in comparing animals of different ages or from different feeding regimes or at different times of the year because variations in gut ‘fill’ were eliminated.7. There were no differences between singles and twins in the relationship of the fresh weights of the parts of the body to empty body weight, except that development of the liver and the blood was rather slower for singles.8. Little evidence was found of a difference in rate of development of the alimentary tract between singles an d twins, although the log an d square root transformation suggested a possible difference in reticulo-rumen size in favour of twins, significant at the 5% level.

Reduced Activity

Spontaneous running activity during ad libitum feeding, fasting and refeeding was studied in inbred yellow mice. These studies suggest that the yellow gene per se is not associated with reduced activity and that inbred yellow mice have intact hypothalamic feeding centers. The relationship of these findings to obesity in yellow mice is discussed.

The Relationship

Objective was to define a mathematical model that better explain the relationship of the animals weight depending not only on the animals age but also on the animals morphometric measurements. 40 piglets, half Duroc-Large White blood, were used, 20 males and 20 females, from 3 to 35 days of age (lactation phase) initially weighing 1.518 ± 0.121 kg and from 36 to 66 days of age (calving phase) with a body weight of 7.010 ± 0.704 kg. The animals were weighed weekly on a digital balance. The relationship of animal weight, age and morphometric measurements of male and female piglets were performed using regression models: existing, linear and power. The models were evaluated according to nine criterialinear model was the most adequate to explain the weight of male pigs, while for female pigs was the power. The age of the pig, the shank and palette length, as well as the circumference of the shank jointly explain the weight of the male piglets. The weight of females is explained jointly by age, body length, thorax and hip circumference.

Coconut crab (Birgus latro) is a crustacean that has a large size until four kilograms. The study  aimed to analyze sex ratio and growth pattern including the relationship of thorax length - body weight, thorax width - body weight and cephalothorax length plus rostrum - body weight in Daeo (Morotai Island), Laigoma (South Halmahera District) and Fitako (North Halmahera District). The sex ratio was determined using χ2 test and the growth pattern was tested by the b value through t test. The results showed sex ratio of 1: 0.9 in Daeo (n = 581), 1: 0.6 in Laigoma (n = 24), and 1: 2 in Fitako (n = 31). The relationship of thorax length, thorax width and cephalothorax length plus rostrum with body weight were strongly correlated (R2> 70%). The growth pattern of coconut crab in Daeo was negative allometric, while in Laigoma and Fitako were negative allometric and isometric.

The experiment was conducted with the objective of to evaluate the comparative feeding value of improved forages as a replacement of concentrate mix with its economic benefits on feed intake, body weight gain and carcass parameters of Afar goats. Twenty-five yearling intact male Afar goats with initial mean body weight of 15.05±1.25 (mean ± SD) were used for the experiment in randomized complete block design. The experimental animals were grouped in to five blocks of five animals based on their initial body weight and each animal within each block was randomly assigned to one of the five treatment diets. Treatments were grazing (Ad libitum) + 100% concentrate mix (wheat bran and noug seed cake) (T1), grazing (Ad libitum) + 100 % mixed forage (Rhodes and cowpea) (T2), grazing (Ad libitum) + 50 % mixed forage (Rhodes and cowpea) + 50% concentrate mix (T3), grazing (Ad libitum) + 25 % mixed forage (Rhodes and cowpea) + 75% concentrate mix (T4), and grazing (Ad libitum) + 75 % mixed forage (Rhodes and cowpea) + 25% concentrate mix (T5). The experiment was consisted of feeding trial followed by carcass evaluation. The supplement given at the rate of 300gDM/head/day. Water and mineralized salt block were available free of choice. The concentrate mix was 2:1 (wheat bran and Noug seed cake. The CP content of the NSC (Noug seed cake), WB (wheat bran), cowpea and Rhodes grass were 31.3, 17.4, 16.9 and 8.6 %, respectively. Organic matter and basal intake were not significant difference (P>0.05) among the treatments, while intake of supplement was slightly higher (P<0.05) for T1, T4, T3, than T5 and T2 respectively. Average daily gain in was higher 110g/d (T4). Hot carcass weight was slightly higher (P<0.05) for T4 10.82 kg. The use of sole cowpea and Rhodes grass mix instead of concentrate mix was reduces feed cost and increase net return. Mixture of cowpea and Rhodes grass as sole supplement is relatively comparable to the supplementary value of concentrate mixture to improve Afar goat performance but forage mix was required higher (p<0.05) feed to bring the same weight to other concentrate contained treatment diets.

The importance of lameness in dairy cattle in UK in terms of its economic consequences and welfare considerations is well documented (Russel and others, 1982). While such epidemiological work has identified factors of importance in the aetiology of the various conditions associated with lameness it has been less successful in apportioning their relative importance, particularly for those conditions affecting the hoof. A series of experiments has been conducted at the West of Scotland College over the period 1983 to 1989 mainly investigating the relationship of nutrition and lameness. In one of these Manson and Leaver (1988) found a significant difference in the prevalence of lameness between two groups of cattle fed complete diets containing either 16.1 or 19.8% crude protein. They also found a significant increase in mean locomotion score (LS) and commented that further studies were needed to understand the dietary processes by which the hoof of the cow was predisposed to such problems.The objective of this experiment was to investigate the influence of the type of protein source in the concentrate upon the locomotion of the cows, the incidence and prevalence of lameness and finally on hoof hardness, shape, growth and wear.

A total of seventy-two weaner rabbits of eight weeks of age were used to assess the effects of replacing groundnut cake (GNC) with blood vegetable waste meal (BVWM) in the diets of rabbits. The BVWM was fed to replace dietary GNC at 0, 15, 30, and 45%, with GNC being 15% in the control diet. The four experimental diets were fed ad libitum for a period of eight weeks. BVWM was analyzed to contain a crude protein value of 62.35%. There were comparable feed intake values by rabbits on all the diets although the rabbits in the higher replacement levels of BVWM tended to have consumed more of the feed. There were significant increases (P<0.05) in body weight gain by rabbits as the BVWM level increased in the diet. Similarly, the feed to gain ratio improved and nitrogen digestibility increased (P<0.05) with higher levels of BVWM in the diet. This study shows that rabbits can tolerate the 45% BVWM replacement of groundnut cake effectively.
