ESTIMATION OF CALCIUM REQUIREMENT OF GROWING YANKASA LAMBS BY FACTORIAL METHOD

Fifty-two Yankasa lambs of mixed sexes age, 6 to 8 months, were used in this study to determine calcium requirement. Varying levels of dietary calcium viz: 0.28, 0.42, 0.56, 0.70, 0.86, 0.99 and 1.15% were tested in a Completely randomized design. Phosphorus was kept constant at the level in the control ration. The criteria of adequacy employed included clinical observations, growth performance and mineral retention. No clinical abnormality was Observed among the groups throughout the experimental period. Although growth performance improved with increase in dietary calcium level, treatment effects among groups on 030, 0.86, 0.99 and 1.15% dietary levels were not significant (P > 0.05). Apparent dry matter digestibility and calcium retention improved with increase in dietary calcium. Mean calcium requirement for lambs was 305 mg/day/kg body weight. Comparisons with the findings of some temperate workers showed that while the endogenous calcium loss for lambs in this region was lower, their requirement for calcium Was higher than those in the temperate region

Calcium requirement of Japanese quail (Coturnix coturnix japonica) chicks in Plateau State, Nigeria

A 6-week feeding trial was carried out to investigate the optimal calcium level in the diet of quail chicks in Nigeria. Four isonitrogenous (25% crude protein) diets containing 0.5, 1.0,1.5 and 2.0% dietary calcium were employed in the trial which involved 480) day-old, uncensored quail chicks. The diets were also isocaloric (2750 kcal/kg M. E). Each dietary treatment was replicated three times. Responses measured included weight gain, feed consumption and feed conversion ratio. Feed intake was higher in diet A (P<0.05) in comparison to others. Diet D recorded lower feed intake (P<0.05) than Diets B and C. Weight gain was similar (P>0.05) for Diets A, B and C which were better than diet D (P>0.05). Feed conversion was better with Diets C And D (P<0.05) than with diets A and B. Diet A was poorer (P<0.05) than diet B in terms of feed conversion. Feed cost/gain ratio was lower (P<0.05) on Diet A than others. Percent bone ash was similar on the diets except Diet C. Results of this study indicated that dietary calcium levels of between 0.5 and 1% will support acceptable weight gain and % bone ash in the first 6 weeks of life.

Calcium Requirement in Relation to Milk Fever and its Economic Impact in Dairy Cattle

The goal of this research was to compile and consolidate the disparate data on calcium requirements in connection to milk fever and its economic impact in dairy cattle. The most frequent mineral-related metabolic condition affecting dairy cows at parturition is milk fever, which occurs most commonly in adult dairy cows two to three days following parturition .It is caused by a severe lack of metabolizable calcium ions in the circulation (hypocalcaemia), and its primarily affects high-producing and high-performing dairy cows that are nearing their maximal output capability. Milk yield, parity, cow breed, and a lack of awareness of basic dairy management and ration formulation are all variables that contribute to milk fever. It reduces milk yield and fertility, which leads to the culling of high-producing dairy cows from a herd. It also raises the expense of animal treatment and the danger of additional parturient disorders such retained placenta, ketosis, displaced abomasum, and environmental mastitis. Intravenous calcium salts, such as borogluconate, at a rate of 2g/100kg body weight, as well as oral calcium solutions, are two methods for treating milk fever in dairy cows. Cases of milk fever, on the other hand, can be minimized with good management, notably through the use of proper feeds and feeding systems .To summarize, management of milk fever is very important because it should be considered as a gateway disease that greatly reduce the chance for full productivity and reproduction of dairy cows. The key to prevention of milk fever is management of a close-up dry cow or management during late pregnancy .Therefore, milk fever management is economically most important, as a result, raising dairy farmers’ awareness of milk fever and optimal ration compositions for their dairy cows is a critical instrument in the fight against milk fever.

Nutritional and care problems in infants with lactose intolerance

Aim. The purpose of the paper was to learn about nursing and nutritional problems in children with lactose intolerance.Material and methods. The study included a group of 343 parents, 320 (93.3%) women and 23 (6.7%) men. A self-written questionnaire containing 27 questions was used for the study. The comparison of responses in the groups was performed using the chi-square test or the Fisher’s exact test where the expected low rates appeared in the tables. The analysis was performed in the R software, version 4.0.2.Results. The most common symptoms affecting the respondents’ children were: abdominal pain (77.3%), abdominal distension (73.5%), overflow in the abdomen (49%), and mucus-mixed stools (45.5%). The symptoms caused the child’s anxiety during sleep in 52.5%, problems with attaching to the breast in 30.3%, and buttocks burns in 23.9%. Statistical analysis confirmed a significant relationship between education and age and the source from which the respondents obtained information on lactose intolerance (p<0.05). Statistical analysis showed that the financial situation had no effect on calcium supplementation in breastfeeding women while on a lactose-free diet (p>0.05). It is worth noting, however, that only 10.5% of the respondents declared calcium supplementation while on a lactose-free diet.Conclusions. It is important to confirm the diagnosis with an examination, as an incorrect diagnosis may lead to a number of problems without obtaining the desired effect. In children with symptoms of lactose intolerance, meeting the daily calcium requirement is essential.

Mathematical model for the prediction of available phosphorus and calcium requirements for European quails of 16-36 days old

Were used 724 quails, with initial weight of 105.05±1.40g to determine the model requirements for European quails 16-36 days old. Were used 384 quails for the maintenance requirement experiment and 240 for the gain requirement experiment and the remaining 100 quails composed the birds of the comparative slaughter. Maintenance requirement: the treatments consisted of four levels of feed offerings (100, 75, 50 and 25% of consumption ad libitum) with four pens and four quails per pen for each climatic environment (18, 24 and 28ºC), being 192 quails for each nutrient under study. Gain requirement: the requirements of the studied nutrients for gain were determined from 240 quails, created and fed ad libitum, being 120 quails for each nutrient studied, that is, 30 quails were slaughtered at 21, 26, 31 and 36 days of age. The quails of the reference slaughter comprise the same as the experiment for determining the maintenance requirement. In conclusion. The prediction equations for estimating the requirements were: 1) Pr (mg/quail/day) = (27.029 + 1.5943 × T) × kg0.75 + 12.24 × WG, in which Pr is the phosphorus requirement, kg0.75 is metabolic weight (kg), WG is weight gain (g/quail/day). 2) Ca (mg/quail/day) = (158.93 - 5.187 × T) × kg0.75 + 23.66 × WG, in which Ca is the calcium requirement, kg0.75 is metabolic weight (kg), WG is weight gain (g/quail/day), T is temperature.
