Preference Responses

The response of male geese, turkeys, Japanese quail and chickens to dietary levels of 0.5, 1, 2.5, 5, 10, 20 and 30% alfalfa meal was measured, using a two-choice feed preference test. At each alfalfa level, the birds were given a choice between the alfalfa-containing diet and an alfalfa-free diet. At levels of 10% or more alfalfa meal, all species showed a significant (P < 0.05) preference for the alfalfa-free diet. At a dietary level of 5% alfalfa meal, all species except chickens discriminated against the alfalfa-containing diet and preferred the alfalfa-free diet. Geese discriminated against the alfalfa-containing diet at 2.5% alfalfa, while no species showed discrimination at alfalfa levels of 0.5 and 1%. The birds did not discriminate between low- saponin and high- saponin alfalfa-containing diets, each compared at alfalfa levels of 1, 5, 10 and 20%. Quinine sulfate was included at levels of 0.01, 0.05 and 0.1% of the diet; discrimination against the quinine-containing diets was noted, indicating that poultry can detect substances in the diet perceived as bitter by humans.

Preference Tests

In two-choice feed preference tests, growing swine selected an alfalfa-free diet over diets containing alfalfa at alfalfa levels of 1% and higher. They selected diets containing low saponin alfalfa over the same dietary level of high saponin alfalfa, but rejected both in favor of an alfalfa-free diet. In a similar two-choice test, swine discriminated against quinine sulfate at all dietary levels above.05%.

Abstrak Penelitian mengenai korelasi genetik dan fenotipik bobot badan umur empat minggu dengan bobot telur telah dilaksanakan di Program Studi Peternakan Fakultas Pertanian Universitas Majalengka. Tujuan penelitian yaitu untuk mempelajari korelasi genetik dan fenotipik bobot badan umur empat minggu dengan bobot telur. Percobaan dilakukan pada 369 ekor puyuh betina yang merupakan keturunan pertama dari pejantan 60 ekor dan betina 120 ekor yang ditetaskan dalam 3 periode penetasan. Metode penelitian menggunakan hubungan saudara tiri sebapak (paternal halfsib correlatian) dengan pola (nested unequal subclass number). Parameter genetik yang diamati yaitu heritabilitas, korelasi genetik dan korelasi fenotipik bobot badan umur empat minggu bobot telur. Hasil penelitian menunjukan bahwa nilai heritabilitas bobot badan umur empat minggu dan bobot telur yaitu 0,563+0,226 dan 0,584+0,281 termasuk kategori tinggi. Nilai korelasi genetik dan fenotipik bobot badan umur empat minggu dengan bobot telur yaitu 0,824+0,187 dan 0,693+0,245. Hal demikian menunjukan bahwa seleksi untuk bobot telur dapat dilakukan pada bobot badan umur empat minggu Kata kunci : heritabilitas, korelasi genetik dan fenotipik, bobot badan dan bobot telur puyuh Abstract The research was conducted at animal husbandry studi program faculty of agricultural Majalengka University. The object of research were study about four-week body weight and eggs weight heritability’s, and than genetic and fenotipic correlation between four-week body weight and eggs weight. Material used were 369 female japanese quail from 60 sire and 120 dam from third periode of hacthery. The method which applied was experimental. The data were analyzed statistically using unequal subclass number design. The result of research estimated heritability obtained using faternal halfsib correlation were four-week body weight 0,563+0,226 was high category and eggs weight 0,584+0,281was high category. Genetic and fenotipic correlation between four-week body weight and eggs weight 0,824+0,187 dan 0,693+0,245. This result shows that selection of one trait will give advantage respon to another trait.

Alfalfa Hay

Alfalfa hay treated with a commercial preservative containing 80% propionic and 20% acetic acid was evaluated as a feed for horses. In a two-choice preference test, horses preferred untreated hay (P < 0.05). When yearlings were fed either treated or untreated hay for 1 mo, there was no difference in feed consumption or weight gain indicating that when given no choice, horses find hay treated with propionic and acetic acid acceptable.

In the first of three experiments, 60 prepuberal gilts (12–13 wk old) were fed diets containing 0.01 (control), 0.16, 0.36, 0.47, 1.28 and 2.21 mg zearalenone (ZEN) kg−1 feed for 63 d. Vulvovaginitis occurred in some gilts fed the control diet; there was a trend (P < 0.01) towards heavier uteruses as the dietary level of ZEN increased. Experiment 2 involved 16 gilts allocated in pairs in noncontiguous pens and fed diets containing 0.01 and 2.21 mg ZEN kg−1 feed for 42 d. No control gilt exhibited vulvovaginitis when separated from a treated gilt by an unoccupied pen while all eight of the treated gilts showed vulvovaginitis. Results suggested that estrogenic metabolites in the urine of gilts eating ZEN-contaminated feed might, if ingested, induce vulvovaginitis in other untreated gilts. Experiment 3 involved 40 gilts and four diets (0.01, 0.36, 0.47 and 1.28 mg ZEN kg−1 feed). The gilts were bred and were necropsied between days 52 and 55 of pregnancy. The incidence of vulvovaginitis differed (P < 0.01) among diets, tending to increase with higher ZEN levels. Fewer gilts fed the two higher levels of ZEN could be bred than those fed the lower ZEN levels. Serum progesterone concentrations ranged from 0.1 to 0.6 ng mL−1 for prepubertal gilts, and from 22 to 29 ng mL−1 during early pregnancy. Fetal mortality, while not significantly different, was numerically less for the control gilts than for those fed the ZEN-treated diets. Feed intake and weight gain were not affected significantly, by the inclusion of zearalenone in any of the experiments. The data indicated that zearalenone did not have serious effects on the reproductive efficiency of young gilts at levels below 0.5 mg kg−1 feed.
