Effect of birth weight of piglets on growth rate and rearing performance up to 8 weeks of age. The aim of the experiment was to determine the effect of the birth weight of piglets on their rearing results up to 56 days of age, as expressed by growth rate and survival. Observations were made on 277 crossbred piglets from 22 litters of F1 sows (Polish Landrace ´Polish Large White) derived from crossbred boars (Duroc ´Pietrain), which were kept and fed the same way. Piglets were reared with mothers for 5 weeks and observed for 8 weeks. At 1, 7, 21 and 56 day of age, piglets were individually weighed. The body weight on day 1 of age served as a basis for dividing the piglets into groups I, II, III and IV (≤1.2; 1.21-1.39; 1.40-1.59; and ≥1.60 kg body weight, respectively). Coefficients of correlation were estimated between body weight on day 1 of age and at 7, 21 and 56 days of age, and daily gains. The mean body weight of the piglets on days 7, 21 and 56 differed between groups I, II, III and IV (P ≤0.01) and depended on the birth weight (r=+0.773, r=+0.567, r=+0.504). In the subsequent rearing periods, daily gains in groups I-IV increased and the differences between the groups showed similar relationships. Differences between groups II and III were small (P>0.05), and those between groups I and IV considerable and highly significant. With the increasing mean body weight at birth, piglet survival increased and was higher in group IV vs I by 13.64 percentage points. The birth weight ≥ 1.60 kg ensured the best growth rate and survival of the piglets.

This study was conducted to evaluate the predictions of dry matter intake (DMI), average daily gain (ADG), and faecal nitrogen (N) excretion by the Cornell Net Carbohydrate and Protein System Version 6.1.26 (CNCPSv6) in China. A total of 71 bulls from two imported breeds, Limousin and Simmental, and three local breeds: Luxi, Jinnan and Qinchuan were selected in China. Data required by the CNCPSv6 model were collected, and model predictions were generated for animals of each breed. The regression equation between observed and predicted DMI for these cattle was: YOBS = 0.93XCNCPS + 0.48 (R2 = 0.94; P < 0.001), with an intercept not different from zero and a slope not different from unity. The proportion of deviation points lying within the range –0.4 to 0.4 kg · d–1 was 90.1%. The regression equation between observed and predicted ADG was: YOBS = 1.07XCNCPS – 0.05 (R2 = 0.92; P < 0.001), with an intercept not different from zero and a slope not different from unity. About 78.9% of points fell within the range –0.1 to 0.1 kg/d for these cattle. Model-predicted faecal N excretion for the cattle breeds was close to the observed values. The regression equation between observed and predicted faecal N excretion was: YOBS = 1.04XCNCPS – 1.48 (R2 = 0.94; P < 0.001), with an intercept not different from zero and a slope not different from unity. About 73.3% of the points fell within −4 and 4 g per day. These results show that the CNCPSv6 model using actual feed fractions can give good predictions of DMI, ADG and faecal N excretion with different beef cattle breeds in China.

Целью соответствующего опыта было сравнение результатов откорма свиней с использованием кормосмеси составленной из ячменя с примесью мясной и костной муки или казеина (класса II или III) как источников белка. Количество белковых прибавок отвечало польскому стандарту кормления сельскохозяйственных животных. Опыт охватывал 224 помесных свиней держимых в станках (7 голов на станок). Не наблюдались существенные различия в средних привесах и в использовании кормов между опытными группами. Результаты убойного выхода 36 свиней (по 12 голов в группе) не показывали существенных различий между группами. Результаты опыта позволили констатировать, что казеин II-го и III-го класса и мясная н костная мука отеoественного производства характеризуются сравнительно хорошими кормовыми достоинствами как белковые прибавки в ячменю в рационах для растущих поросят.

The study was aimed to determine an effect of various feed mixes on finishing White Improved billies reared until 6 months of age. The experiment was carried out in three replications. The study focused on the following sets of traits: body weight gain, feed consumption per weight gain, carcass and half-carcass measurements, slaughter performance and carcass tissue composition. The experiment has shown that farm-made balanced diets, which have a slightly lower level of protein but are richer in fibre, can be successfully used in feeding finishing White Improved billies. Namely, animals fed on this diet, although showing some performance parameters slightly reduced, achieved their slaughter value and meat quality similar to those fed on commercial CJ feed.

W żywieniu owiec zastosowano formę chronioną białka łatwo hydrolizującego (rdzeń kazeinowy osłonięty natłuszczoną etylocelulozą) oraz węglowodany o ograniczonej podatności na fermentację w przed żołądkach (ziarno kukurydzy). Jeden z zestawów eksperymentalnych zawierał również dodatek siarczanu sodu. Analiza chemiczna treści żwacza i dwunastnicy tryczków z przetoką umożliwiła ustalenie kierunku oraz zakresu metabolizmu składników pokarmowych dawek. W drugiej fazie badań dokonano oceny wykorzystania energii oraz białka zmodyfikowanej diety przez obserwacje wzrostu i produkcyjności wełnistej młodych maciorek merynosa polskiego. Ustalono, że zastosowanie osłony dla części białka dawki wpłynęło na ograniczenie jego strat, o czym świadczy obniżenie koncentracji amoniaku w płynnej treści żwacza oraz wzrost ilości azotu ogólnego i nieamonowego w dwunastnicy. Udział siarczanu sodu przyczynił się do zwolnienia tempa fermentacji i pogłębienia jej propionowego charakteru, w stosunku do zaobserwowanego w dietach z kukurydzą. Zastąpienie 1/3 białka ogólnego dawki formą chronioną w 40% przed degradacją mikrobiologiczną, a części węglowodanów łatwo fermentujących - ziarnem kukurydzy, przy równoczesnym zastosowaniu siarczanu sodu w żywieniu maciorek rosnących (VI-XI miesiąca życia) spowodowało: 10-procentowy wzrost wydajności wełny czystej, przy mniejszym jednostkowym zużyciu energii netto (o 9,l%, białka ogólnego (o 8,5%) i suchej masy (о 11,3%) 22,7% efektywniejsze wykorzystanie energii metabolicznej na tworzenie wełny niż u owiec żywionych tradycyjnie. Stwierdzono też, że przy podobnym zużyciu energii (netto i metabolicznej), białka ogólnego i suchej masy na jednostką przyrostu masy ciała, znacznie lepsze było fizjologiczne wykorzystanie energii metabolicznej w grupie doświadczalnej niż kontrolnej (współczynnik produkcyjny wyższy o 8,5%).
